Light emitting diode (LED) became popular rapidly by the appearance of blue LED. Three color (R, G, B) emitting LEDs are utilized for the image display system by the development of multi color emitting LED. White LEDs became to commercial base by combining blue or UV light sources for excitation and materials for fluorescence. White LEDs are prevailing for general lighting applications. A single tip with the power of 5W became line up for commercial market owing to the research for high intensity LEDs. As a result, LEDs are replacing the market of conventional incandescent lighting and even head lights of the automobile. In this study, we aim to fabricate the white and R, G, B lighting system using high brightness LEDs for the lighting of holograms instead of a conventional halogen lamp.
