Abstract
PURPOSE: To form a reflector excellent in heat resistance, and having a narrow angle light distribution or a precise light distribution without applying secondary machining such as surface polishing or the like by forming of polyimide resin film of specified thickness. CONSTITUTION: The base body 1 of a reflector is molded, for example, into a quadric surface body of revolution with polyimide resin film of a thickness of 0.1 to 0.3 mm having surface smoothness. A flange part 2 and an annular rib 3 are integrally formed on the outside of the opening edge of the base body 1, an annular rib 4 is respectively formed on the periphery of the lamp insertion hole 7 of the base body 1 top part and plural ribs 6 are radially formed at predetermined intervals on the reflection face 5 of the base body 1. Since the infrared transmittance decreases if a film thickness exceeds 0.3 mm, it is not preferable. Thereby, the reflector can be formed with the lightweight film having good formability so as to have shape holding intensity and be superior in heat resistance.
