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… Web11 de fev. de 2013 · Green 3mm, Red 5mm and White 10mm LEDs. 5mm LEDs can be so bright, they are often used as illumination (lighting something up, like a flashlight, we'll talk about this next).; 3mm LEDs are not as bright but are smaller, and are good for indication (like an LED that tells you something is on).They're not as good for illumination because …
