PROJECTION LIGHT SOURCE BY USING MULTI CHIP LIGHT EMITTING DIODE

摘要

PURPOSE: A projection light source by using a multi chip light emitting diode is provided to remove a cooling pan needed for eliminating the heat of very high temperature generated from a conventional lamp since the high pressure mercury lamp is in place of the conventional lamp by serving as an engine light source to be a rear projection display as a necessary element. CONSTITUTION: A projection light source by using a multi chip light emitting diode is characterized in that one chip is formed by arranging an arbitrary semiconductor utilized as any one of R, G and B light sources at a predetermined region at a specific pattern by emitting a light beam having a wavelength corresponding to the portion corresponding the difference of energy during the movement from a low level of the energy to a high level of the energy.
