ABSTRACT:
A projector light source which facilitates molding of a reflector for obtaining a complicated reflecting surface and provides an improved cooling efficiency, which is characterized by molding the reflector of the light source using heat resistant plastic mixed with a high heat conductive material, whereby a molding accuracy is drastically improved compared to a heat resistant glass reflector, and a highly efficient light source is implemented by increasing a degree of design freedom using a high-order non-spherical reflecting surface. Furthermore, heat conductivity is increased by the use of a high heat conductive material for the reflector and heat dissipation to an outside is facilitated.
