Why Does an LED Emit Light?

Here we need some theory. An LED is an electronic semiconductor component that emits light when charged with an electric current. In this process, light is not produced by heating a coil, as in the conventional incandescent bulb, but by electronic reactions inside the semiconductor. However, the light issued by the LED only comes from a narrow range of the entire spectrum, i.e., only a small section of the theoretically available light radiation is actually produced.

LED technology is now bright enough to enable LED lighting in the entertainment industry. Lighting solutions for film studios, theatres, stage lights, disco lighting and theme parks like colored spotlights, flood lighting, color changing lighting, wall wash lighting, cove lighting and column lighting are all deployed. All areas have the challenge that controllable dynamic colors are needed to make a real difference. LEDs are the perfect solution for these applications. They combine color capabilities with safety, long life, and enable more innovative and smaller light solutions.
