Abstract
A reflector for light source of a projector, comprises a cup-shaped part that is formed by forging or casting from aluminum metal or alloy or the like metal, inner face of the cup-shaped part being mirror finished by ultra-precise cutting technique or by grinding with buff or diamond powder as not to have grooves or distortion; and a barrel portion disposed at center of the cup-shaped part and configured to receive an electric-discharge lamp. Omitted thereby is a coating of silicone-based resin that is a must for a reflector formed by metal spinning technique as to cover up the grooves and distortion. Thus, good heat conductivity of the aluminum metal or the like is not hampered, as to achieve a reflector for high-luminance lamp with high power consumption.
