LED stands for light emitting diode and is a solid-state semiconductor device. Only recently, LED’s of sufficient power have become available to make practical LED film lighting possible. LED’s are extremely efficient but are still limited in overall light output when compared to any of the other light sources.
LED’s are by nature monochromatic, producing only a single wavelength of light. So the challenge of LED lighting has been in creating a full spectrum white light. This can be done in two ways, either by combining the light of red, green and blue emitting LED’s, or with white LED’s whereby the visible white light is actually created by phosphors that are excited by an ultra-violet emitting LED.
