Voyager Missions Facts
NASA's Voyager program was part of a mission to explore the solar system beyond our comfort zone.
Two spacecraft – Voyager 1 and Voyager 2 – were launched several decades ago, and their combined data has provided us with some of the most exciting insights into space exploration yet!
It is these two probes that have enabled us to identify countless new planets, moons, comets, gas giants, and more. Uncovering unprecedented information about our universe on a regular basis.
The Voyager probes represent both a scientific and technological accomplishment in terms of world-leading exploration techniques as well as something inspiring for humans in terms of leaving the safety of our home planet to explore distant worlds.
As such, we can only imagine what secrets are out there waiting for humanity's curiosity and ingenuity to uncover them through the wonders that comprise the Voyager program.

Overview of Key Points Of Planetary Exploration
The Voyager Mission to Explore Interstellar Space (VIM)
Voyager 1 and 2 are NASA spacecraft.
They launched in 1977 to study the outer solar system.
They have visited Jupiter, Saturn, Uranus, and Neptune.
Voyager 1 is the farthest human-made object from Earth.
Both Voyagers carry a record of Earth sounds, images, and messages.
They are still sending back data and could operate until 2025.
Launch: NASA's Voyager 1 and Voyager 2 took off from Cape Canaveral during the summer of 1977.
Mission: The goal was to make the most of a 175-year planetary line-up, reducing their travel time.
Objectives: Their studies focused on Jupiter and Saturn, including the rings of Saturn.
Deployment: On August 20 and September 5, respectively, they were ready for takeoff.
Jupiter: On March 5, 1979, Voyager 1 made its journey to Jupiter.
Saturn: Voyager 2 arrived at Saturn on July 9, 1979, while Voyager 1 followed on November 12, 1980.
Uranus & Neptune: The programmed mission was fulfilled, but through remote-control reprogramming, they were also able to reach Uranus (Voyager 2 on January 24, 1986) and Neptune (Voyager 1 on August 25, 1989).
Success: After 5 years in space, both spacecraft achieved their goals – an astonishing feat!
Heading out into the unknown, two incredible Voyagers took on an interstellar mission in 1977. It was a journey through time and space to explore strange new worlds no human had seen before.
Twelve years later, the twin spacecraft had reached 40 and 31 Astronomical Units (AU) from the Sun – that's 11 billion miles! But they were just getting started.
In 2012, Voyager 1 became the first human-made object to enter interstellar space. And in 2018, its companion Voyager 2, followed suit. By 2025 they'll be even further out – at 13.8 billion and 11.4 billion miles, respectively!
Not only have these adventurers captured stunning images of our Solar System, but each carries a unique message too! Carefully selected by scientist Carl Sagan and linguists from all over the world, this golden disc holds greetings from humanity in 55 languages plus music and video.
Voyager 1 was like no other. In 2012, it became the first spacecraft to cross beyond the heliosphere and enter interstellar space. Since then, it has been flying longer than any other spacecraft in history.
It's also a record breaker, outstripping its twin Voyager 2 all the way to Jupiter, Saturn, and even beyond. Along the way, it discovered five new moons and even an amazing new ring around Saturn.
And 44 years later (in 2021), Voyager 1 is still going strong in the constellation of Ophiuchus, at a whopping 154 AU (23 billion km) and counting! It's an incredible testament to human technology and has truly broken boundaries.
From uncovering unknown celestial giants to flying into uncharted galactic realms – we can owe so much of what we know to this intrepid explorer. Even after all these decades, Voyager 1 continues its journey of discovery with enthusiasm and unwavering determination.
Mariners 11 and 12 was the original design behind Voyager 1 and 2. Launching on August 20, 1977, these vessels got just 473 seconds of audio plays at Jupiter during their closest approach at 400,785 miles (645,000 km) away.
This close pass showed us a wide range of objects: Callisto, Ganymede, Europa, Io, Iapetus, and Amalthea moons.
The images that started arriving in 1981 gave us a clear view of what Saturn held in store; ring spokes & kinks, A-ring and F-ring, as well as many smaller bodies like Hyperion, Enceladus, or Tethys, could be seen for the first time. Not even dreaming about Helene Telesto and Calypso yet, which were discovered later on!
During its 4.5-year voyage, Voyager 2 reached Uranus and its newly discovered moons, the first human-made object to do so.
On August 25, 1989, Voyager 2 flew past Neptune from about 2,980 miles (4,800 kilometers).
There are three main features in the planet's clouds – Scooter, the Great Dark Spot, and the Lesser Dark Spot.
After such discoveries, 12 years later, time ran out, and NASA renamed the project to Voyager Interstellar Mission (VIM).
VIM will carry on sending messages back to Earth until their power runs out —with it concluding Voyagers' eternal travels into space. An incredible insight for many generations to come!

Kachemak Bay is a 40-mi-long (64 km) arm of Cook Inlet in the U.S. state of Alaska, located on the southwest side of the Kenai Peninsula. The communities of Homer, Halibut Cove, Seldovia, Nanwalek, Port Graham, and Kachemak City are on the bay as well as three Old Believer settlements in the Fox River area, Voznesenka, Kachemak Selo, and Razdolna.
One interpretation of the word "Kachemak" is "Smokey Bay" which supposedly is from an Aleut word describing the smoldering coal seams that used to fill the bay with smoke.
Kachemak Bay is home to Alaska's only state wilderness park, Kachemak Bay State Park. Kachemak Bay State park was the first state park in Alaska. There is no road access to most of the park; visitors must arrive by airplane or boat.
Kachemak Bay is also home to the Kachemak Bay National Estuarine Research Reserve, the largest reserve in the National Estuarine Research Reserve System. It is a very active site of research and education. The bay hosts a remarkably high level of biological activity, due in part to water circulation patterns which keep shellfish larvae and nutrients in the bay. While surface waters push nutrients out into the bay, ocean currents push them back into the bay, creating a very fertile environment. Both fish and shellfish are abundant in the bay, year-round. Waterfowl and shorebirds occupy the bay during all but the winter season, while waterbirds and marine mammals including otters, seals, porpoise, and whales remain in the bay all year. The bay provides winter homes for 90% of the seabird and waterfowl populations of Lower Cook Inlet. Land mammals are frequently seen during the warmer seasons. Moose, coyote, and bears are frequently seen.
The tides at Kachemak Bay are extreme, with an average vertical difference (also called mean range) of over fifteen feet (15.53 ft, 4.73m), and recorded extremes of over thirty-one feet (31.72 ft, 9.67m) as measured at the Seldovia Tide Station. The highest tide on record is over twenty-five feet (25.25 ft, 7.7m) above MLLW and occurred on November 15, 1966. The lowest tide on record is almost minus six and a half feet (-6.47 ft, -1.97m) from MLLW and occurred on April 27, 2002.

Baselworld 2019 is just two days away and before the beginning of this massive tradeshow, Design Limited Edition offers you what will be the most anticipated modern watches design trends during this year's edition.
This spectacular show that runs from March 21st through 26th this year, is an annual gathering of new high-end watches by luxury brands, and the 2019 edition is nearly here. Perfect for someone with a luxury lifestyle, Baselworld 2019 is also a good time to be a watch lover, particularly if you like to discover and explore new watch design trends. Take a look at all the Baselworld 2019 design trends and get amazed by stunning timepieces with an exclusive design.
Watch materials like bronze, titanium, carbon, and ceramic will continue to be a popular way for watchmakers to stand out. Other exotic, high-tech materials we couldn't previously even imagine like IWC's Ceratanium, Panerai's Carbotech, or Girard-Perregaux's carbon glass are examples of resources developed for watchmaking that we can also expect to see in this tradeshow.
While green is not quite the new blue, as you can see in this Mont Blanc watch model, a number of gorgeous recent examples have been well received, and some more can perhaps be expected. Other dial colours, as well, like red and "salmon" will be welcome. A. Lange & Sohne will provide craftsmanship masterpieces in this design trend, as we also can see. As many watchmakers learned from experience with blue dials, success with different colours very much depends on the execution of tone and texture.
We all appreciate a genuinely novel and contemporary design watch, but no one can afford to ignore the enthusiasm for vintage re-releases and generally retro-inspired design. During Baselword 2019, the "vintage" trend will be stronger. Some luxury brands have revived watches from eras past and have become truer to the originals, and that includes using smaller case sizes. Beside this, faux-aged effects have also expanded beyond yellow lume to things like speckled dials and even banged-up-looking cases.
Technology is now part of the watch landscape. Luxury brands like Apple are already producing smartwatches with a contemporary design and will be releasing new versions that make last year's obsolete. Further, it wouldn't be surprising to see more brands enter the game. During the Baselworld 2019, we can see new smartwatches that will continue to improve upon battery life, display, ergonomics, and also your luxury lifestyle.
There will be Haute Horlogerie pieces on offer. However, some luxury brands, as Tudor or Seiko, will provide the basic entry-level models in steel, often reviving vintage references, is one-way brands will achieve this.
Stay with us to find out more about the exquisite craftsmanship of Haute Horlogerie and to follow Baselworld 2019.

Exclusive: Matt Mowers Attacks Democrats for Attempting to Cancel New Hampshire Motto 'Live Free or Die'

Former congressional candidate Matt Mowers on Friday attacked New Hampshire Democrats for attempting to cancel the state's motto, "Live Free or Die."
"Following @ChrisPappasNH's lead, the Liberals are once again trying to cancel Live Free or Die. Live Free or Die isn't just a slogan on a license plate — it's our way of life in the Granite State. We won't let them cancel New Hampshire," Mowers wrote about Rep. Chris Pappas (D-NH) and the Democrat Party.
Following @ChrisPappasNH's lead, the Liberals are once again trying to cancel Live Free or Die.
Live Free or Die isn't just a slogan on a license plate — it's our way of life in the Granite State.
We won't let them cancel New Hampshire. #NHpolitics #NH01 pic.twitter.com/wfkwcgndKd
— Matt Mowers (@mowers) August 6, 2021
"As Liberals across America continue their crusade to cancel the American spirit, it comes as no surprise that they have once again turned their sights on our state's great motto," Mowers told Breitbart News. "This isn't something new. When Chris Pappas was a State Rep. long ago, he pushed to cancel Live Free or Die while at the same time calling Granite Staters brainwashed for fighting against an income tax. Pappas didn't represent New Hampshire then, and he sure doesn't now."
But New Hampshire state Rep. Steve Woodcock (D) defended cancel culture by suggesting the motto is triggering and that he is concerned school children will "cut" their "arms" because "they are in pain" due to the motto:
"If I am seeing students in middle school and high school who had their arms cut all the way up from razor blades because they are in pain, and I put on the front door of every building 'Live Free or Die,' I'm concerned about the trigger that sends that these adolescents, as they come in every day."
"I'm a retired school principal and I've seen the mental health issues our young people face," Woodcock said. "I've seen the cutting, the self-mutilation. It scares me that you have people whose frontal lobes haven't developed and they walk into a school building and it says 'Live Free or Die,' it can be triggering for suicide or rash actions."
To defend the motto, state Republicans have introduced a bill to give local school boards the ability to determine what is best for their children, blocking the state government from tyrannical overreach. House Bill 69 states the following:
No power or authority of the state of New Hampshire, or any political subdivision thereof, shall in any way restrict, or be construed to restrict, the authority of any school or school district to display the national motto, "In God We Trust," or the state motto, "Live Free or Die," in any school building.
Republican strategist Patrick Griffin called the cancelation "comical."
"The Democrats demonstrated their preferred state motto would be: 'Live Taxed, Regulated and Oppressed by the Government, or Die.' That'd look pretty snappy on a license plate," Griffin stated. "These people are so out of touch, so tone-deaf, that they demonstrate again their ability to alienate members of their own party and independents will run from them."

La rivière de la Guinaudée est un cours d'eau qui coule à Haïti dans le département de Grand'Anse et l'arrondissement de Jérémie. Elle rejoint le golfe de la Gonâve à environ cinq kilomètres à l'Est de la ville de Jérémie.

Géographie
La rivière de la Guinaudée prend sa source dans les contreforts du massif de la Hotte à l'ouest de la péninsule de Tiburon. Le cours d'eau se dirige vers le nord et se jette dans le golfe de la Gonâve entre les bouches de deux larges fleuves Grande-Anse à l'Ouest et Voldrogue à l'Est qui l'enserrent depuis sa source.

Son lit est étroit, mais ses crues sont importantes. Un nouveau pont enjambe la rivière de la Guinaudée à la hauteur du Vieux-Bourg pour permettre à la route nationale N°7 de franchir ce cours d'eau après avoir franchi ceux de la Voldrogue et de Grande-Anse.

The remaining Brooklyn Nets schedule appears just as daunting as the recent road stretch. However, there are some winnable games on tap.
After Thursday's disappointing 123-110 loss to the Philadelphia 76ers, Brooklyn Nets center Ed Davis shared his sentiments about his team.
Brooklyn is certainly cutting it close when it comes to missing the playoffs. The Nets have lost five out of their last seven games; barely riding the tightrope of contention. Brooklyn sits half a game ahead of eighth-place Miami and one game atop of ninth-place Orlando.
That's not to say that this disappointing stretch was completely unexpected. Thursday's game in Philadelphia was the grand finale to a road-trip that had spelled doom from the start. Brooklyn was the underdog in each of its last seven games. Not to mention, three of Brooklyn's opponents rank within the top-seven in net rating over the course of the last month: Utah, LA (Clippers), and Portland. (The Nets, meanwhile, sit at spot number 18).
Glancing ahead at Brooklyn's remaining schedule, it doesn't appear that things will get any easier. Although the Nets enjoy the luxury of a three-game homestand next week, Brooklyn hosts a trio of teams with a combined .678 winning percentage: Toronto, Milwaukee, and Boston.
From there, the Nets head back on the road for a brutal back-to-back against the aforementioned Bucks and the grinding Indiana Pacers, both on the road. Yikes.
Brooklyn's season comes to a close at home in a potential play-in game for the eighth-seed against the Miami Heat. Although it's tough to project the importance of this game, there's a very good chance that both teams could be fighting for their playoff lives.
In order to make the playoffs, Brooklyn needs to pull off at least one upset during the next two weeks. Based on how the team has looked lately against above .500 teams, that seems like a tall order.
Fortunately, there's a silver lining to this story.
In three of Brooklyn's final six games, its opponent will be on the wrong side of a back-to-back. Yes, finally. The scheduling gods are smiling upon the upstart team from Brooklyn!
The first of these three games occurs this Saturday, as Brooklyn hosts the up-and-down Boston Celtics. Both Boston and Brooklyn have had seasons mired in highs and lows.
The comparison between these two squads should probably end here. In Brooklyn's case, yo-yoing through the schedule can be attributed to the young team outperforming its expectations (and to some degree, talent).
The Celtics, on the other hand, don't have a viable excuse for their middling performance. For a team that was expected to win the Eastern Conference, the 2018-2019 season has been vastly disappointing.
On Friday, Boston hosted the Indiana Pacers in an exciting matchup that was likely a first-round series. The Pacers, owners of the league's third-best defense, made the Celtics work for everything. Even though Boston came out on top, the grueling nature of jostling with Myles Turner and the rest of Indiana's swarming defense will certainly take a toll on the body of 32-year-old Al Horford—the heart and soul of the Celtics' defense and, arguably, the off-court leader of this young team—among others.
Playing a potentially worn down Celtics team the very next night is a major advantage for Brooklyn. The 2019 Boston Celtics can be described in many words. Resilliant isn't one of them. According to TeamRankings.com, in 13 games, Boston is 5-8 in games with no rest period; the 18th-best back-to-back record out of all 30 teams. Opportunity for the upset is certainly lurking.
The second team facing Brooklyn in the second game of a back-to-back is the Milwaukee Bucks. On Sunday, March 31, the Bucks head to Atlanta to play a promising Hawks team. What makes this game so interesting is its start time: Milwaukee and Atlanta tip off at 12:30 p.m. ET. This means that the Bucks could be up painstakingly early in order to get in the necessary shootarounds and workouts.
Brooklyn has its third crack at Milwaukee the very next day. Their previous meetups didn't exactly go well for the Nets. But this Bucks team is in a much different state. Its star, Giannis Antetokounmpo, recently turned his ankle during Thursday's game against the LA Clippers. With the MVP race between the Greek Freak and James Harden heating up by the hour, it's doubtful that Giannis sits the April Fool's Day game out. Still, though, there's a chance that he's playing at 90 percent.
The Bucks will also be without a few role players. Although the team has recovered nicely with Malcolm Brogdon on the mend, they will still miss his presence. Nikola Mirotic will also almost certainly be held out of Monday's game. A shortened rotation could pose a major problem for the Bucks considering the grueling nature of its schedule.
The final team that faces Brooklyn on a back-to-back is its playoff rival—the Miami Heat. As mentioned before, this meetup could be an elimination game for the ages; the winner makes the playoffs while the loser secures a low-upside, late-lottery pick in a top-heavy draft.
Fortunately for the Nets, the Heat will be forced to play the red-hot Philadelphia 76ers on Tuesday, April 9. Then, on April 10, Miami heads to Brooklyn in a high-stakes season finale. The Nets should have the leg up.
Brooklyn's mettle will be assuredly tested in the final six games. If the Nets are the playoff team we think they are, they'll need to feast on all three of their potentially fatigued opponents.

SCAVENGER HUNT POST
Today, I am hosting Brianna Shrum, author of Never, Never for the YA Scavenger Hunt, and fans are in for a VERY special treat!!
Brianna's Bio: I'm a YA author living in Colorado with my high-school-sweetheart-turned husband and two little boys. I love all things villainous, magical, and strange, and when I'm not writing, am usually buried in someone else's words in a book. You can usually find me drinking chai and reading by my Harry Potter Christmas tree, which I will probably never take down.

James Hook is a child who only wants to grow up.
When he meets Peter Pan, a boy who loves to pretend and is intent on never becoming a man, James decides he could try being a child - at least briefly. James joins Peter Pan on a holiday to Neverland, a place of adventure created by children's dreams, but Neverland is not for the faint of heart. Soon James finds himself longing for home, determined that he is destined to be a man. But Peter refuses to take him back, leaving James trapped in a world just beyond the one he loves. A world where children are to never grow up.
But grow up he does.
And thus begins the epic adventure of a Lost Boy and a Pirate. This story isn't about Peter Pan; it's about the boy whose life he stole. It's about a man in a world that hates men. It's about the feared Captain James Hook and his passionate quest to kill the Pan, an impossible feat in a magical land where everyone loves Peter Pan.
Except one.
Today's exclusive content is a brand new Never, Never bonus scene!!! Enjoy...
"I want to show you something," said Tiger Lily.
James raised an eyebrow and threaded his fingers through hers. "Oh?"
"I'd considered keeping it entirely to myself, but you've worn me down. I've never…never shown this place to anyone."
"Anyone?" he said, but when he said "anyone," what he really meant was "Peter."
Her fingers tightened minutely around his for a moment as they made their way through the darkest part of the forest. This was the place that had always frightened him most as a child—where the trees banded so close together that you couldn't make out the sky. Even Peter had steered clear, though he'd threatened to wallop anyone who'd brought it up.
But Tiger Lily wasn't afraid of anything.
She pushed ahead and James followed, holding his hook close to his side so it wouldn't get caught in the bramble.
"There," Tiger Lily said, and she ducked into a little indent in the earth, surrounded by shimmering leaves. James followed, trying to ignore the hairs raising on the back of his neck at being swallowed by the dark. And when he pushed through, he found himself in a much larger space than he'd expected—an entire room in the earth, vines and grass and fingerlike branches that spread out overtop them. It was surprisingly warm in here, given the damp, and when he wriggled in a bit further, breaking through the wall of branches, he drew in a sharp breath.
"Told you," she whispered, and she grabbed for his fingers again.
"The fairies," he breathed. They were everywhere. He and Tiger Lily were hidden, staring at them from the shadows as they flew around, dancing and spinning and laughing. The air was washed with the sound of tinkling bells, and lit with little houses, staircases and room that glowed gold and thin as thread.
"How did you find this place?" James said, suddenly feeling the sort of wonder that only came to the young.
"By not being afraid," Tiger Lily whispered , lips brushing against his ear. His fingers curled in the black soil beneath them and she said, "One can wander into a good many secrets if one chooses not to be afraid." Her breath on his ear and neck sent a spray of goose bumps over his skin.
"Oh is that the way of it?" James turned his face quickly, so that his mouth met hers. She smiled into his lips and he ran his fingers through her hair, hook over the back of her neck.
"So this is your secret?" he said, voice low.
"I wish I had one with which to repay you," he said.
Tiger Lily cocked her head and raised an eyebrow. "Oh no, I absolutely expect one in return. Fair's fair, James Hook."
"I have none to show you. But I can tell you," he said.
"I don't believe you, pirate," said Tiger Lily. "But I accept your offer."
James ran his fingers down her back while the fairies played and flitted like the stars around them. "If I were to show you a secret, it would be London. Where the stars stand still in the sky. The fog is cold and tastes like nothing but the rain, and it wraps around your ankles," he said, sliding his hook and fingers up her bare calves. "There's a clock in the middle of the city, so large that when it chimes, you can feel it in your chest." His hand slipped up to her hip, and then his fingers were brushing her collarbone.
"I doubt it feels like this," she said, glancing down at his hand.
"Oh, of course it does. I'm no scoundrel. I'm only telling you a secret."
Tiger Lily ran her teeth over her lip and said, "You, James, are a scoundrel to your very bones."
He tipped up one corner of his mouth and leaned over her. "Are you fed up with me then? You don't wish to hear of the breeze that kisses your eyelids, or the salt of the sea on the wind that touches your tongue, or—"
"You fool pirate," she said, and she grabbed his shirt by the laces and kissed him, fingers knit in his hair, back pressed against the leaves. He braced himself on the ground, chest pressing into hers, and skated his teeth over her jaw, up to her ear. "Do you wish to hear more of London?"

THE GREAT HUNT Release Week!!


I have been informed of a child with a type of lymphoma that due to his chemotherapy treatment will require blood transfusions over the course of the next 5-6 months. The preference is to have blood donated from known people. He is A+ and a patient at Long Island Jewish Schnieder's Hospital in New Hyde Park, New York. Anyone able to help with this lifesaving and extremely important mitzvah should contact: ritacarp@yahoo.com. If you can pray for him, his name is: Yitchak Itzik Ben Raizel.
However, can this be the true answer? Even if Yosef was the biggest, strongest human being that ever walked the face of the earth, which he wasn't still, how could he stand up to the likes of Eisav and his descendants, who tended to be the biggest and strongest human beings who ever walked the face of the earth?
Furthermore, the picture the Torah paints of Yosef is not so reassuring either. He is called a "lad," not usually too complimentary of a term in the Torah, and a shepherd to boot, not usually the most aggressive and strongest of people either. If ever there was a David-and-Goliath scenario, it is this: Yosef against the Eisav dynasty!
Rashi, it seems, was also bothered by this question, and therefore he brought a posuk from Ovadiah to explain to us what we need to understand. The posuk says, in essence, who cares how big the field is and how large the stocks of wheat are? One small flame can bring the whole thing down in a matter of hours, and undo in minutes what may have taken years to build up. That is the power of fire and the weakness of straw.
In other words, our question was predicated on the assumption that Yosef was the straw and that Eisav and his descendants were the flame. How can a piece of straw stand up to a single flame, let alone an entire arson brigade? Comes along the prophet Ovadiah who says that we have it backwards: Eisav is the weak and vulnerable straw, and Yosef and his descendants are the powerful flame that cannot be extinguished.
What is the source of Yosef's fire?
In fact, we are not really interested in whether or not Yosef was a financial success, or the most popular person in Egypt: .
After all, Eisav has, and continues to produce most of the highly successful business people and most stunning men and women. However, that is b'derech teva - through "natural" means, a function usually of "mazel," often hard work (though not always), genetic processes, and perhaps grooming. Yosef's success, indeed his very existence, was completely a function of obvious Divine Providence - of supernatural means.
One could argue that Eisav's success is better. After all, the rabbis teach us that "according to the effort is the reward," and Yosef seemed to achieve his successes effortlessly while Eisav and his descendants have had to work hard to carve out lives for themselves. However, one would be arguing wrongly, because that is not what the rabbis had in mind by "effort."
In fact, of the six sefiros that govern history - Chesed, Gevurah, Tifferes, Netzach, Hod, and Yesod - and which correspond to our main ancestors (in order): Avraham, Yitzchak, Ya'akov, Moshe, and Aharon, it is Yesod that corresponds to Yosef HaTzaddik. This itself is extremely telling of the source of Yosef's strength and ability.
For, the trait of Yesod is that it acts as the main exit to reveal on the outside what was previously hidden on the inside. In the sefiros, it is the place where the light of Ain Sof (G-d) makes its way from sefirah to sefirah down to this world for our benefit, and is finally revealed in the world.
The gematria of "tov" (tes-vav-bais) is seventeen - the age of Yosef at the beginning of this week'sparshah.
If you think it is easy to fashion oneself into a vessel holy enough to receive and transmit the light of G-d, even to a level as spiritually low as the one upon which the Egyptians lived, and remain spiritually intact, think again. Yosef may have been born into the job, but when on his own he used his spiritual assets to improve upon that which he was Divinely given, drawing down the Heavenly light on his own, forcing it, if you will, to join with him which resulted in all that he touched turning into gold.
In hindsight, it is clear that Yosef ended up in jail as a stepping stone to become second-in-command of Egypt. Certainly, there are other more pleasant ways to promote a person in life. However, Divine Providence chose this route for Yosef for reasons that may be known only to Heaven.
On the other hand, the fact that Yosef was able to succeed and remain spiritually unscathed even in the lowest part of the lowly Egypt, was a tremendous comment about Yosef's spiritual stature. Furthermore, he did not lose his ability to reveal the unknown even while he was there, evident by his ability to correctly interpret the dreams of Paroah's servants who "happened" to be in prison at the same time he was there.
This, perhaps, is the basis of Yosef's ability to play such an important role in the Final Redemption of the Jewish people, when they seem to be at their spiritual lowest. If the first Moshiach to come - Moshiach ben Yosef - is a spiritual heir to his illustrious ancestor, then a major part of his success will be his ability to reveal the hidden ONLY FOR THE SAKE OF HEAVEN, (many can do it for their own gain and glory), to act as a pure and successful channel for the Light of G-d.
In Chapter 38, Rav Shmuel Vital reveals that the Arizal told his father that he (the Arizal) had only been sent into the world to teach him (R' Chaim) Sod (Kabbalah). It would be Rav Chaim Vital's role to "filter" what he received from the mouth of his master and make it accessible to those from the rest of Klal Yisroel whose understanding would permit them entry into this most holy realm of Torah.
Son of Truth! That is Moshiach ben Yosef, someone from whom the unadulterated truth will flow like a stream of clear, refreshing, life-giving water. He will be a person so pure, so devoted to the will of G-d, that the Light of G-d will be drawn to him like metal filings to a magnet, and all that he does will be successful. His truth will be like fire that will burn up the straw - the lie - of Eisav.
If so, why must he die in the process of bringing redemption (Succah 53a), only to be revived again by Moshiach ben Dovid, the final Moshiach?
It is a good question, and one that will have to wait until next week to be answered, b'ezras Hashem, as we further discuss the traits of Yosef HaTzaddik and his role in redemption.
The Torah is called the Original Light of creation of "good," implying that it was an accurate fulfillment of the Divine intention when creating the world. This is what "good" always means: the results have fulfilled the intention. Thus, evil is by its very nature that which violates the intention of the Creator, at least as far as we are told by the Torah and by those who uphold It.
Adam's violation of the commandment to not eat from the Tree of Knowledge of Good and Evil was such a violation, and as such, a contravention of the very concept embodied by the Supernal Light - a light alluded to by the number "thirty-six," and one that we will see later, has deep Kabbalistic significance.
A word that is really not a word, for you will never find it again in Tanach. You will find the same four letters and even in the same order, but they will have different vowel sounds and therefore, a completely different pronunciation, as in "Eichah."
No, here the word is "Aiyekah?" and though translated as, "Where are you?" it is really, instead, as Rebi Shimon ben Pazzi said: it is a gematria of the number thirty-six. But why? Why would G-d come to Adam with a number instead of a real question, to which Adam could provide a real answer?
"How have you acted in a way that reveals the Hidden Light that shone for thirty-six hours, and which embodies all that thirty-six stands for?"
It was a tough question to answer. However, in it is an important clue that indicates that, as much as the Original Light of creation was hidden in the first week of creation, it is still possible to reveal it through our actions, or conversely, keep it hidden. If so, then at least we can understand why there can be an allusion to this spectacular light a millennia later in the Ner Shel Chanukah, the Chanukah Lights, a holiday that celebrates a victory that occurred in the THIRTY-SIX century from creation.


The city of Pratt awarded Mary Harms with the Joe Wynn Volunteer of the Year award Monday at their regular meeting.
Mary Harms was presented the 2018 Joe Wynn Volunteer of the Year Award at Monday night's Pratt City Commission Meeting.
Harms was nominated for the award by Pratt Park Superintendent Mark Eckhoff for her dedication in keeping the Lemon Park Lights burning brightly during each Christmas season.
"Mary spends hours and hours on the Christmas lights," Eckhoff said.
Harms said her role in keeping the lights aglow each Christmas holiday is to check each string of lights, one-by-one, to make sure there are no burnt-out bulbs.
"There's a LOT of strings," Harms said.
The only way to do this is to plug in each and every string of lights and do a visual check that all the bulbs are lit.
To assure no bulb is left unchecked, Harms said she starts in late August and works two to three nights a week, staying at the task for about an hour and a half for each volunteer session.
Harms usually works alongside her sister Theresa Miller whose husband Ron Miller serves as volunteer overseer of Lemon Park Lights displays.
As the Christmas season approaches, Mary said she steps up her volunteer sessions to weekends as well.
"I'm honored to receive the award," Harms told city commissioners as she accepted her award Monday night.
Harms, who has worked in the rebate department of Stanion Wholesale Electric since 1997, will be memorialized with a plaque in her honor that will be placed in Lemon Park alongside plaques of previous recipients.
The award memorializes Joe Wynn who, among other things, is remembered for his association as one of the owner-managers of the historic Jett Store at 300 South Main where Sears is now located.

The invention relates in general to a backlight module and a liquid crystal display device, and more particularly, to a light emitting diode package, a light guide pipe, and a backlight module and a liquid crystal display device using the same.
2. Related Art
It has been known in the art that a liquid crystal display panel in a liquid crystal display device is not self-luminous, the liquid crystal display panel needs a backlight module to provide backlight in order to display images. A cold cathode fluorescent lamp or a hot cathode fluorescent lamp is generally used in a conventional backlight module as a light source.
However, cold and hot cathode fluorescent lamps include poisonous substances, such as mercury. It is not easy to recycle cold and hot cathode fluorescent lamps after long-time uses as the fluorescent lamps pollute the environment easily if not properly recycled. Furthermore, with the current upsurge in environmental protection consciousness and tendency to recycle all electronic products, backlight modules with fluorescent lamps are recognized as environment unfriendly and, therefore, applicability of the conventional fluorescent backlight modules and liquid crystal display devices using the same is lowered greatly.
There is a need for a backlight module and a liquid crystal display device using the same which do not suffer from the disadvantages of the conventional backlight modules and LCDs.
In an aspect, a light emitting diode package comprises a base; a body disposed on the base, wherein the body has a first surface with a first recess formed therein; and a plurality of first light emitting diode chips disposed in the first recess for providing the light emitting diode package with sidelight.
In a further aspect, a light guide pipe comprises a column having an external circumferential surface and an internal reflection surface; and a plurality of prism structures disposed between or on at least one of the external circumferential surface and the internal reflection surface for scattering light received by the light guide pipe.
In another aspect, a backlight module comprises a frame, a light guide pipe and a light emitting diode package. The frame comprises a base board and a side board, wherein the base board and the side board define a containing space. The light guide pipe comprises a column disposed in the containing space and over the base board, wherein the column has an external circumferential surface and an internal reflection surface. The light guide pipe further comprises a plurality of prism structures disposed between or on at least one of the external circumferential surface and the internal reflection surface for scattering light received by the light guide pipe. The light emitting diode package comprises a base disposed on the base board, and a body disposed on the base board and inserted into the column after penetrating the external circumferential surface and the internal reflection surface. The body has a first end surface and a second, opposite end surface. The first end surface and the second end surface have a first peripheral recess and a second peripheral recess, respectively. The first peripheral recess corresponds to the second peripheral recess. A plurality of first light emitting diode chips are disposed on a bottom of the first peripheral recess for emitting sidelight toward one end of the light guide pipe. A plurality of second light emitting diode chips are disposed on the bottom of the second peripheral recess for emitting sidelight toward the other end of the light guide pipe.
In yet another aspect, a liquid crystal display comprises the above described backlight module, a first polarizer disposed over the backlight module; a liquid crystal display (LCD) panel disposed over the first polarizer; and a second polarizer disposed over the liquid crystal display panel.

DETAILED DESCRIPTION OF EMBODIMENTS
FIG. 1A is a front view of a light emitting diode package according to a first embodiment of the invention. FIG. 1B is a side view of the light emitting diode package in FIG. 1A. FIG. 1C is a three-dimensional view of a base and a body of the light emitting diode package in FIG. 1A. FIG. 1D is a front view of the light emitting diode package in FIG. 1A further including fluorescent powder and gel. FIG. 1E is a back view of the light emitting diode package in FIG. 1A further including the fluorescent powder and the gel.
As shown in FIGS. 1A˜1B, a light emitting diode package 10 includes a base 11, a body 12 and several first light emitting diode chips 13a. The body 12 is disposed on the base 11 and has a first end surface 12a. A first peripheral recess 12c is formed on the first end surface 12a. The first light emitting diode chips 13a are disposed on a bottom of the first peripheral recess 12c for providing the light emitting diode package 10 with single-direction sidelight, such as +y direction sidelight. The light emitting diode package 10 at least emits circular single-direction sidelight. Other light patterns are not excluded.
For example, the body 12 is a cylinder or a polygonal column. A cylindrical body is illustrated as an example in the present embodiment. Furthermore, the first light emitting diode chips 13a include white light emitting diode chips or a combination of red (R), green (G) and blue (B) light emitting diode chips. The first light emitting diode chips 13a are preferably arranged linearly in one row and in an order of RGB. Or, the first light emitting diode chips 13a are preferably arranged in two rows and relatively staggered in an order of RGB. Moreover, the body 12 includes a thermal conductive material, a reflection material or a ceramic material. The base 11 includes a heat sink material for dissipating heat generated by the light emitting diode package 10. Also, the base 11 and the body 12 are preferably formed integrally. Besides, a circuit board is preferably disposed on or inside the base 11. The circuit board electrically connects an anode and a cathode of each first light emitting diode chip 13a to power terminals or a converter. For example, the circuit board is a flexible circuit board or a printed circuit board.
As shown in FIG. 1C, the light emitting package 10 further includes a reflection material 14. The reflection material 14 is disposed on a wall of the first peripheral recess 12c. The reflection material 14 preferably includes high reflective metal or metal alloy, such as aluminum or silver or alloys thereof. Furthermore, as shown in FIG. 1D, the light emitting diode package 10 further includes a fluorescent coating, i.e., powder 15, and gel 16. The fluorescent powder 15 is coated on the first light emitting diode chips 13a. The gel 1 6 is filled in the first peripheral recess 12c and covers the first light emitting diode chips 13a and the fluorescent powder 16. For example, the first light emitting diode chips 13a include blue light emitting diode chips, and the fluorescent powder 15 includes yellow fluorescent powder. As a result, white light is generated when blue light emitted by the blue light emitting diode chips interacts with the yellow fluorescent powder. Therefore, the light emitting diode package 10 at least emits single-direction lateral white light.
Various combinations of the first light emitting diode chips 13a and the powder 15 are available. For example, blue light emitting diode chips can be combined with green fluorescent powder and red fluorescent powder. Alternatively, purple light emitting diode chips can be combined with green fluorescent powder and red fluorescent powder. Or, purple light emitting diode chips can be combined with red fluorescent powder, green fluorescent powder and blue fluorescent powder. Other combinations are not excluded depending on the desired color of the light emitting diode package 10. Furthermore, the gel 16 is preferably epoxy, poly(methyl methacrylate) (PMMA), polycarbonate (PC) or white gel, which does not affect light emission of the light emitting diode package 10.
As shown in FIG. 1 E, the body 12 further has a second end surface 12b opposite to the first end surface 12a. A second peripheral recess 12d corresponding to the first peripheral recess 12c is formed on the second end surface 12b. The light emitting diode package 10 further includes several second light emitting diode chips 13b. The second light emitting diode chips 13b are disposed in the second peripheral recess 12d. The second light emitting diode chips 13b provide the light emitting diode package 10 with single-direction sidelight, such as −y direction sidelight. Therefore, the light emitting diode package 10 emits two-direction sidelight. Another reflection material is preferably formed on a wall of the second peripheral recess 12d. Fluorescent powder is preferably coated on the second light emitting diode chips 13b. The second light emitting diode chips 13a and the fluorescent powder coated thereon are preferably covered by gel filled in the second peripheral recess 12d. Moreover, the second light emitting diode chips 13b include white light emitting diode chips or a combination of red (R), green (G) and blue (B) light emitting diode chips. Also, the second light emitting diode chips 13b are preferably arranged linearly in one row and in an order of RGB. Or, the second light emitting diode chips 13b are arranged in two rows and relatively staggered in an order of RGB. Other arrangements are not excluded depending on the desired color of the light emitting diode package 10. Moreover, an anode and a cathode of each second light emitting diode chip 13b are preferably electrically connected to power terminals or a converter through a circuit board on or inside the base 11.
FIG. 2A is a three-dimensional view of a light guide pipe according to a second embodiment of the invention. FIG. 2B is a cross-sectional view of the light guide pipe in FIG. 2A viewed along +x direction with yz plane as a cross-sectional plane. FIG. 2C is a magnified cross-sectional view of the light guide pipe in FIG. 2A viewed along +y direction with xz plane as a cross-sectional plane. As shown in FIGS. 2A˜2C, the light guide pipe 20a is for receiving light emitted by a light source from one end of the light guide pipe 20a and for scattering, by refraction, the received light. The light guide pipe 20a includes a column 21 and several prism structures 22a. The column 21 has an external circumferential surface 21a and an internal reflection surface 21b. The internal reflection 21b is arranged for reflecting light received by the light guide pipe 20a. The prism structures 22a can be disposed between the external circumferential surface 21a and the internal reflection surface 21b, or, as can be seen in FIG. 2C, on the external circumferential surface 21a, for scattering light received by the light guide pipe 20a. As a result, the guide pipe 20a scatters light through the external circumferential surface 21a. For example, the column 21a nd the prism structures 22a are formed integrally. Also, the column 21 is preferably a cylinder or a polygonal column. A cylindrical column is illustrated in the present embodiment as an example.
In the present embodiment, the prism structures 22a are disposed on the external circumferential surface 21a. The prism structures 22a include a pattern of dots. The pattern dots are preferably protrusions. For example, a light source is positioned at one end of the light guide pipe 20a. Although the pattern dots are of the same size in the present embodiment, the prism structures 22a are not limited thereto. As seen in y direction, the pattern dots are preferably smaller and less densely distributed when closer to the light source. Therefore, incident light reaches uniformly to an effective application range of the light guide pipe 20a. The pattern dots farther from the light source are preferably bigger and more densely distributed, so that a scattering area of the incident light is larger. Therefore, the refraction effect of the light guide pipe 20a on the incident light is optimized or enhanced. In the present embodiment, although the pattern dots are shown in FIG. 2C to be distributed uniformly on the circumferential surface 21a, the arrangement of the pattern dots on the circumferential surface 21a can be adjusted according to the practical situation. Therefore, the intensity of scattered light in a specific angle range is controllable. Furthermore, the pattern dots are preferably circular or polygonal. Circular prism structures 22a or pattern dots are illustrated as an example in the present embodiment. Also, the light guide pipe 20a in the present embodiment is preferably made of optical grade PMMA or optical grade PC. The light guide pipe 20a is preferably solid or hollow.
A manufacturing method of the internal reflection surface 21b will be briefly explained below. However, the invention is not limited thereto. For example, the column 21 further includes a through hole 21c, and the light guide pipe 20a further includes a reflection material 23. The reflection material 23 is formed, e.g., by coating, on an inner wall of the through hole 21c, so that the internal reflection surface 21a is formed in the column 21.
Refer to FIG. 2D, the internal reflection surface 21b in FIG. 2B formed by a reflection pipe in the column 21 is illustrated. For example, the light guide pipe 20a further includes a reflection pipe 24. The reflection pipe 24 is inserted into the through hole 21c along an axial (arrow) direction, so that the internal reflection surface 21b is formed by the outer reflective surface of the reflection pipe 24 in the column 21. The reflection pipe 24 is preferably inserted in a mold of the column 21 first. Then, the column 21 and the reflection pipe 24 are formed integrally by twice injection molding. Or, the reflection pipe 24 is preferably formed by rolling a pre-cut reflection sheet. After the column 21 is formed, e.g., by injection molding, the reflection pipe 24 and the column 21 are formed integrally and shaped.
When the light guide pipe 20a is hollow, one column, i.e., 24, is preferably inserted into another column, i.e., 21, to form the light guide pipe 20a by twice injection molding in a mold. Or, column 21c an be formed from a sheet by pressing. The prism structures 22a are formed on a surface of the sheet. Then, the sheet is rolled with the prism structures 22a facing outward to form the light guide pipe 20a. Furthermore, the prism structures 22a with the pattern dots are formed on the external circumferential surface 21a of the column 21 by injection molding, printing, pressing or ink rolling.
In the light guide pipe 20a of the present embodiment, the prism structures 22a are formed on the external circumferential surface 21a. As a result, the light guide pipe 20a can be used with a light source that emits light in a pattern corresponding to an annular area between the external circumferential surface 21a and the internal reflection surface 21b. For example, when the area between the external circumferential surface 21a and the internal reflection surface 21b of the light guide pipe 20a is coupled to the first peripheral recess 12c of the light emitting diode package 10 in the first embodiment, circular sidelight emitted by the light emitting diode package 10 enters the light guide pipe 20a through the area between the external circumferential surface 21a and the internal reflection surface 21b. Therefore, by the effects of the prism structures 22a, the internal reflection surface 21b and the light guiding material of the column 21, the light guide pipe 20a scatters the received light to the surrounding environment through the external circumferential surface 21a. Therefore, the light guide pipe 20a of the present embodiment converts circular light emitted by the light emitting diode package 10 of the first embodiment or by another light source to lamp-like light.
In FIG. 3, a cross-sectional view of a light guide pipe according to a third embodiment of the invention is illustrated. The difference between a light guide pipe 20b of the present embodiment and the light guide pipe 20a of the second embodiment lies in prism structures 22b. The same components use the same reference numbers and are not described again.
As shown in FIG. 3, although the prism structures 22b of the present embodiment and the prism structures 22a of the second embodiment all includes pattern dots, the pattern dots of the present embodiment are concave dots or cavities, rather than protrusions. A manufacturing method of the light guide pipe 20b in the present embodiment is substantially the same as that of the light guide pipe 20a in the second embodiment and is not described again. Besides, the distribution and manufacturing method of the prism structures 22b in the present embodiment are substantially the same as those in the second embodiment and are not described again. Furthermore, the pattern dots of the prism structures 22b are preferably circular or polygonal. Circular prism structures 22b are illustrated in the present embodiment as an example. Also, the light guide pipe 20b of the present embodiment is preferably made of optical grade PMMA or optical grade PC. Moreover, the light guide pipe 20b is preferably solid or hollow. The prism structures 22b and the column 21 are preferably formed integrally.
FIG. 4A is a three-dimensional view of a light guide pipe 20c according to a fourth embodiment of the invention. FIG. 4B is a cross-sectional view of the light guide pipe in FIG. 4A viewed along +x direction with yz plane as a cross-sectional plane. The difference among the light guide pipe 20c of the present embodiment, the light guide pipe 20a of the second embodiment and the light guide pipe 20b of the third embodiment lies in prism structures 22c. The same components use the same reference numbers and are not described again.
As shown in FIGS. 4A˜4B, the prism structures 22c of the present embodiment are preferably screw thread prisms. The screw thread prisms 22c include concave screw thread prisms which are formed as continuous or discontinuous helical recesses in the external circumferential surface 21a. Furthermore, each screw thread prism can be continuous or discontinuous. Continuous screw thread prisms are illustrated as an example in the present embodiment. When a light source is positioned at one end of the light guide pipe 20c, the light guide pipe 20c is arranged for receiving light emitted by the light source from that one end of the light guide pipe 20c and for scattering the received light. Although the screw thread prisms with a constant pitch are illustrated in the present embodiment, other arrangements of the prism structures 22c having the configuration of screw threads on the external circumferential surface 21a are not excluded. For example, as seen in y direction, the pitch of the prism structures 22c having the configuration of screw threads is preferably smaller when prism structures 22c are closer to the light source. Also, the prism structures 22c having the configuration of screw threads are less densely distributed when closer to the light source. As a result, incident light reaches to an effective range of the light guide pipe 20c. The pitch of the prism structures 22c is preferably larger when the prism structures 22c are farther from the light source. Also, the prism structures 22c are more densely distributed when the prism structures 22c are farther from the light source. Therefore, a scattering area of the incident light is larger to enhance or optimize the refraction effect of the light guide pipe 20c on the incident light. In the present embodiment, although the prism structures 22c having the configuration of screw thread are shown to be continuous on the external circumferential surface 21a, the prism structures 22c having the configuration of screw threads can be adjusted to be discontinuous according to the practical situation. Therefore, light intensity in a specific angle range is controllable.
Besides, the light guide pipe 20c of the present embodiment is preferably made of optical scale PMMA or optical scale PC. Furthermore, the light guide pipe 20c is preferably solid or hollow. The prism structures 22c and the column 21 are preferably formed integrally. The manufacturing method of the light guide pipe 20c in the present embodiment is substantially the same as that of the light guide pipe 20a in the second embodiment and is not described again.

The manufacturing method of the light guide pipe 20e is illustrated briefly as follows. First, a sheet is formed by pressing. Prism structures or cavities 22e are formed on a surface of the sheet.

FIG. 9A illustrates a front view of a backlight module according to a ninth embodiment of the invention. FIG. 9B is a three-dimensional view of the backlight module of FIG. 9A which is a combination of a frame, a plurality of light emitting diode packages and a plurality of light guide pipes. FIG. 9C is a side view of a light emitting diode package and the corresponding light guide pipe of FIG. 9B on the frame. FIG. 9D is a partial magnified view of the light emitting diode package and the light guide pipe in FIG. 9C on the frame. FIG. 9E illustrates the frame in FIG. 9B.
As shown in FIGS. 9A˜9E, a backlight module 90 includes a frame 91, at least one light guide pipe and at least one light emitting diode package. For example, the backlight module 90 is a direct type backlight module. The light emitting diode package of the backlight module 90 is preferably the light emitting diode package 10 of the first embodiment. The light emitting diode package 10 emits single-direction or two-direction sidelight. The light guide pipe of the backlight module 90 is preferably any light guide pipe of the second to eighth embodiments. A number, e.g., six, of light guide pipes 20a are illustrated as an example in the present embodiment. Each light guide pipe 20a with five light emitting diode packages 10 is illustrated as an example. However, the present invention is not limited thereto and any number of light emitting diode packages and light guide pipes can be used depending on the application. The light emitting diode package 10 and the light guide pipe 20a are illustrated in the first embodiment and the second embodiment, and are not described again.
The frame 91 includes a base board 91a and a side board 91b. The base board 91a and the side board 91b define downwardly concave containing space 91c. The column 21 of each light guide pipe 20a is disposed in the containing space 91c and over the base board 91a. The base 11 of each light emitting diode package 10 is disposed on the base board 91a. As shown in FIGS. 9C˜9D, the body 12 of each light emitting diode package 10 penetrates the external circumferential surface 21a and the internal reflection surface 21b of the corresponding light guide pipe 20a, as shown by arrow in FIG. 9D, and then is inserted in the column 21. As a result, the first peripheral recesses 14 and the second peripheral recesses of the three middle light emitting diode packages 10 are coupled to the corresponding areas between the external circumferential surface 21a and the internal reflection surface 21b in the middle region of each light guide pipe 20a. The first peripheral recess 14 and the second peripheral recess of the two end light emitting diode packages 10 located at the ends of each light guide pipe 20a are coupled to the corresponding areas between the external circumferential surface 21a and the internal reflection surface 21b at the ends of the light guide pipe 20a. In each light guide pipe 20a, the middle three light emitting diode packages 10 emit two-direction sidelight to the light guide pipe 20a along the axial direction toward two ends of the light guide pipe 20a. The two end light emitting diode packages 10 emit at least single-direction sidelight to the light guide pipe 20a along the axial direction toward the other end of the light guide pipe 20a.
In the present embodiment, the light emitting diode packages 10 preferably penetrate the base board 91a and then are fastened to the base board 91a. For example, after penetrating the base board 91a, the light emitting diode packages 10 are fastened to the base board 91a by hooking, adhering, screwing, hinging, welding, wedging, riveting or socketing or the like. A screw hole of the base board 91a is preferably a blind hole instead of a through hole. As a result, dust is prevented from entering to the containing space 91c, and light leakage is decreased. As shown in FIG. 9E, the base board 91a has several through holes 91e. Each through hole 91e is arranged for enabling one or more light emitting diode packages to penetrate the base board 91a. As a result, the light emitting diode package 10 can be easily replaced from the back of the backlight module 90. Furthermore, the backlight module 90 includes a reflection film 97 or a reflection layer. The reflection film 97 is disposed on the base board 91a and the side board 91b for reflecting light. The reflection layer can be coated on the base board 91a and the side board 91b for reflecting light also. After penetrating the reflection film 97 or the reflection layer, each light emitting diode package 10 protrudes on the upper surface of the reflection film 97 or the reflection layer. Furthermore, the frame 91 further includes a top board 91d. The top board 91d connects to the base board 91a through the side board 91b. The backlight module 90 further includes a diffusion plate 98. The diffusion plate 98 is disposed on the top board 91d and covers a top opening of the containing space 91c for diffusing light. The backlight module 90 further includes an optical film set 99.

The backlight module 90 of the present embodiment shortens a light mixing distance between the light emitting diode package 10 and the diffusion plate 98 due to the use of the light source module assembled by the light emitting diode packages 10 and the light guide pipes 20a. As a result, the thickness of the backlight module 90 is decreased greatly, and the applicability of the backlight module 90 is increased.

In the present embodiment, after penetrating the base board 101a, each light emitting diode package 10 is fastened to the base board 101a. For example, after penetrating the base board 101a, the light emitting diode package 10 is fastened to the base board 101a by hooking, adhering, screwing, hinging, welding, wedging, riveting or socketing or the like. Screw holes of the base board 101a are preferably blind holes instead of through holes. As a result, dust is prevented from entering the containing space 101c, and light leakage is decreased. As shown in FIGS. 10C˜10D, several through holes 101e are formed on the base board 101a. Each through hole 101e is for enabling part of one or more light emitting diode packages 10 to penetrate the base board 101a. Therefore, the light emitting diode packages 10 can be easily replaced from the back of the backlight module 100 directly. Furthermore, the backlight module 100 includes a light guide plate 106 and a reflection film 107. The light guide plate 106 has a first surface 106a, a second surface 106b and a third surface 106c.

The reflection film 107 is disposed over the third surface 106c for reflection light, so that light entering the light guide plate 106 through the second surface 106b emits out through the first surface 106a. Several pattern dots 106d, such as protruding dots, are formed on the third surface 106c. When closer to the second surface 106b, the pattern dots are smaller and distributed more densely. When farther from the second surface 106b, the pattern dots are bigger and distributed less densely. The backlight module 100 further includes a diffusion plate 108. The diffusion plate 108 is disposed over the first surface 106a for diffusing light. The backlight module 100 further includes an optical film set 109.
