How an LED Light Bulb Works - Ideas & Advice Lamps Plus

A light-emitting diode (LED) is a semiconductor device that emits light when current flows through it. Electrons in the semiconductor recombine with electron holes, releasing energy in the form of photons. The color of the light (corresponding to the energy of the photons) is determined by the energy required for electrons to cross the band gap of the semiconductor. White light is obtained by using multiple semiconductors or a layer of light-emitting phosphor on the semiconductor devi… Web4 de mai. de 2024 · LED lights are easy to dispose of, unlike CFLs.
