A light emitting diode or LED - a semiconductor device, which is designed to convert electrical energy into light. The emitted light is within a narrow spectral range, the spectral characteristics of which depend on the chemical composition of the semiconductor used there in.
Lighting LED devices - very spread in the market of lighting equipment. Its represent a new generation of lighting which no longer belongs to the termal sources of lighting. Floodlights, lights, blinders, scanners, devices with full motion and others. New generation, radically different from the traditional lighting fixtures with halogen or metal halide lamps, has been actively included in use. Also, LED lights are more durable than their tube counterparts and have more compact dimensions. As emitter LED devices can serve one or more, and even a few tens of light-emitting diodes.
