How do leds emit light

In this issue we will cover how LEDs emit light. When a suitable voltage is applied to the leads, electrons are able to recombine with electron holes within the device, releasing energy in the form of photons. But, even better, there are LEDs (light-emitting diodes) that are just as bright as bulbs, last virtually forever, and use hardly any energy at all.

In light emitting diodes (LEDs light is produced by a solid state process called). Unlimited potential, the LED can surely be hailed as the light source of the future.
