ABSTRACT:
An improved plastic reflector member for a parabolic aluminized reflector (PAR) lamp is disclosed and, in particular, the use of said improved plastic reflector member for an all plastic PAR lamp or a PAR lamp which uses said improved reflector member. Said improved plastic reflector member utilizes a variable thickness wall member to form the parabolic shaped cavity wherein the wall thickness of its planar walls is sufficiently greater in the rim sealing region than in the adjoining wall region of said parabolic cavity to avoid mechanical and heat distortion.
