There is a revolution in the lighting market, and the catalyst is light-emitting diode technology better known as LED. LED is a semiconductor device that produces light. Essentially, it is a solar cell working in reverse. Instead of converting light into electricity, it converts electricity into light. Unlike conventional light sources: incandescent, halogen, fluorescent, compact, high-intensity, discharge, LED emits light in a narrow range of wavelengths such as red, green, or blue. For general illumination, various approaches (such as colour mixing) are applied to obtain white light.
