mo funciona un LED y caracteri
sticas Un LED es un diodo emisor de luz que en su interior contiene un material semiconductor que al aplicarle una pequena corriente ele
ctrica produce luz. La luz emitida por este dispositivo es de un determinado color que no pro- duce calor. A diferencia de los emisores convencionales, el led no presenta aumento de temperatura. El color que adquiere la luz emitida por este dispositivo dependera
 de los materiales utilizados en su fabricacio
n. En realidad el material semiconductor caracteriza la luz, que puede ser ultravioleta o infrarroja e incluye todas las gamas de colores visibles al ojo humano. La luz, por tanto, no es generada por el calentamiento de un filamento (prin- cipio de las la
mparas incandescentes y halo
genas) sino por un una corriente entre los polos del dispositivo, llamada electroluminiscencia. Lente pla
stica Plastic lens LED Features of a LED and how it works A LED is a light-emitting diode which has a semiconductor material inside. When a small electric current is applied to this semiconductor, it produces light. The light emitted by this device is a particular colour which does not produce heat. Unlike conventional light emitters, a LED does not cause an increase in temperature. The colour of the light emitted by this device will depend on the manufac- turing materials. The semiconductor material determines the light colour, which can be ultraviolet, infrared or any colour within the range of lights visible to the human eye. Hence, light here is not generated by heating a filament (which is the princi- ple of incandescent and halogen lamps) but by a current travelling between the poles of the device, which is known as  electroluminescence .
