What is LED?
What is LED? A light-emitting diode (LED) is a semiconductor device that emits light when an electric current flows through it. When current passes through an LED, the electrons recombine with holes emitting light in the process. LEDs allow the current to flow in the forward direction and blocks the current in the reverse direction.
LED Light Bulb Energy Calculator: Watts and kWh
Input the wattage of your LED Light Bulb. If you are unsure enter the average wattage for a LED Light Bulb: 10. How many watts does a LED Light Bulb use? The average LED Light Bulb uses 10 watts. Your devices wattage may be different depending on the brand, size, or other factors.
Light-emitting diode physics
Light-emitting diodes (LEDs) produce light (or infrared radiation) by the recombination of electrons and electron holes in a semiconductor, a process called "electroluminescence".The wavelength of the light produced depends on the energy band gap of the semiconductors used. Since these materials have a high index of refraction, [note 1] design features of the devices such as …
