In 1802, Humphry Davy invented the first electric light. He experimented with electricity and invented an electric battery. When he connected wires to his battery and a piece of carbon, the carbon glowed, producing light. His invention was known as the Electric Arc lamp. And while it produced light, it didn’t produce it for long and was much too bright for practical use.

Over the next seven decades, other inventors also created “light bulbs” but no designs emerged for commercial application. More notably, in 1840, British scientist Warren de la Rue enclosed a coiled platinum filament in a vacuum tube and passed an electric current through it. The design was based on the concept that the high melting point of platinum would allow it to operate at high temperatures and that the evacuated chamber would contain fewer gas molecules to react with the platinum, improving its longevity. Although an efficient design, the cost of the platinum made it impractical for commercial production.

In 1850 an English physicist named Joseph Wilson Swan created a “light bulb” by enclosing carbonized paper filaments in an evacuated glass bulb. And by 1860 he had a working prototype, but the lack of a good vacuum and an adequate supply of electricity resulted in a bulb whose lifetime was much too short to be considered an effective producer of light. However, in the 1870’s better vacuum pumps became available and Swan continued experiments on light bulbs. In 1878, Swan developed a longer lasting light bulb using a treated cotton thread that also removed the problem of early bulb blackening

Summarize the text as it relates to the design of the light bulb.

1802 main, hamphri davy ne pehali electric lite kaa avishkaar kiya.unhone bijli ke saath prayog kiya or ek electric bydaree kaa avishkaar kiya.jab vah taron ko apni bydaree or carbon ke ek tukade se jodta he, to carbon chamakate hue, prakaash kaa utpaadan karata he.unke avishkaar ko electric arq lamp ke rup main janaa jaataa tha.or jab yah prakaash kaa utpaadan karata tha, to yah lambey samay tak iskaa utpaadan nahin karata tha or vyaavhaarik upyog ke liye bahut ujjwal tha.

agle saat dashakon main, anya avishkaarakon ne "lite balb" bhi banaaya, lekin vanijyik anuprayog ke liye koi dizine nahin ubhara.adhik vishesh rup se, 1840 main, british vaigyanik warren de laa rue ne ek vaikum tub main ek kundalit platinum philament ko sanlagn kiya or iske madhyam se ek vidyut pravaah paarit kiya.dizin is avadharana par aadhaarit tha ki platinum kaa ucch pighalane bindu ise ucch taapmaana par sanchalit karne kii anumati degaa or khaali kiye gaye kaksh main platinum ke saath pratikriya karne ke liye kam gas anu honge, jo isaki dderghaayu main sudhaar karegaa.haalanki ek kushal dizin, platinum kii laagat ne ise vanijyik utpaadan ke liye avyavhaarik bana diya.

1850 main joseph wilson swaan ke naam se ek angreji bhautik vigyaani ne ek khaali kaanch ke balb main carbonated paper philaments ko gherkar ek "lite balb" banaaya.or 1860 tak unke paas ek kaamkaaji prototip tha, lekin ek achche vaikum kii kami or bijli kii paryaapt aapurti ke parinamswaroop ek balb tha jiskaa jeevankaal bahut kam tha jise prakaash kaa ek prabhavi nirmaataa mana jaataa tha.haalanki, 1870 main behatar vaikum pump uplabdh ho gaye or swaan ne prakaash balbon par prayog jari rakhaa.1878 main, swaan ne ek upachaarit sooti dhaage kaa upyog karke ek lanbaa sthaayee prakaash balb viksit kiya, jisane shuruaati balb bluekaning kii samasya ko bhi hataa diya

paath ko saranshit karen kyonki yah prakaash balb ke dizin se sambandhit he.

pehali electric lite kaa avishkaar 1802 main hamphri davy dwaara kiya gaya tha.uske baad, saat dashakon se adhik samay tak vanijyik anuprayog ke liye koi dizin feet nahin tha, haalanki anya avishkaarakon ne prakaash balb banaae.1940 main, haalanki, british vaigyanik warren de laa rue ne ek vaikum tub main sanlagn coild platinum philament kaa upyog karke ek prakaash balb viksit kiya.platinum kii ucch laagat ne is dizin ko vanijyik utpaadan ke liye avyavhaarik bana diya.1850 main, joseph wilson swaan ne carbonated paper philaments kaa upyog karke ek balb banaaya, lekin vaikum kii kami or paryaapt bijli kii aapurti ne apane jeevankaal ko chota kar diya.haalanki, 1870 ke dashak main ek behatar vaikum kii uplabdhta ne swaan ko ek lambey samay tak chalane vaale balb ko viksit karne main sakasham banaaya, saath hi saath upachaarit sooti dhaage kaa upyog karke shuruaati balb bluekaning kii samasya ko hal kiya.
