From power to light: How LED works

An incandescent lamp lights up because a filament is heated by electrical energy. An LED bulb lights up because electrical energy is directly converted into light energy. Therefore, LED bulbs don’t get nearly as hot as incandescent bulbs. LED means Light Emitting Diode. An LED is a semiconductor. In fact, a diode is the simplest form of a semiconductor.

Semiconductors are a special material that is contaminated so that one side is negatively charged and the other is positively charged. Or put another way: one side has an excess of electrons, while the other side has holes in which the extra electrons can fall. In the LED, the semiconductor is made of a special material - typically gallium arsenide - that releases particles called photons, when the electrons fall into a hole. When you power an LED, the electrons move, falling into the holes and emitting light. Depending on the production technology used and the semiconductor materials, LEDs can emit l
