LEDs have long since become ubiquitous in their role as humble status indicators for domestic and industrial appliances. A conventional LED emits close to monochromatic light, and the number of possible colors is limited. Many approaches exist that transform this narrow spectrum into one recognizable as white light. Since there are only three types of color-sensitive receptors or cones in the human eye, one can generate white light by the generation of light with two or three distinct colors. One can show that the most efficient white light source consists of two monochromatic sources emitting at complementary wavelengths. For two 100% efficient monochromatic sources emitting at 448 nm and 569 nm, the maximum theoretical luminous efficacy to produce white light is 400 lumens per Watt of optical power. So this has led to the research work of photon recycling semiconductor light emitting diode-PRS-LED
