A healthy vegetarian diet is high in plenty of nutrient-dense foods, such as fruits, vegetables, healthy fats and whole grains, and often low in saturated fat, cholesterol and sodium. However, nutritional deficiencies might still occur, and supplementation will be necessary.
LED stands for light emitting diode. LEDs are a solid state device and do not require heating of a filament to create light. Rather, electricity is passed through a chemical compound that is excited and generates light. LEDs are not bulbs or lamps in the true sense of the word and application.
An infrared LED is a tiny light emitting diode used to power devices such as remote controls. The wavelength transmitted by infrared light carries a signal that tells devices what to do (such as, with the remote, telling it to change the TV channel). Differences between Infrared & Visible Light LEDs.
