发明名称 LAMP REFLECTOR
摘要 A lamp assembly has a reflector body formed of an injection moulded, low profile, thermoset polyester moulding composition with an integral sleeve having a stop internally of the body. A tubular bulbholder has an external flange engaging against the stop and carries a bulb. The reflector body has upper and lower paraboloidal portions of different focal length joined together by a step facing the lower paraboloidal portion. The step decreases in width inwardly from the periphery of the reflector body. The lower paraboloidal portion has a greater focal length than the upper paraboloidal portion which projects forwardly away from the rear of the reflector body to a greater extent than the lower paraboloidal portion. A mounting flange around the reflector body has a planar surface against which a lens element engages. The mounting flange is disposed between shield and the rear of the reflector body.
