ABSTRACT:
Improved mechanical stop means are provided for a sealed prefocused light source mount for a parabolic aluminized reflector (PAR) lamp and, in particular, to improved mechanical stop means for an all-plastic PAR lamp or a PAR lamp comprising a plastic reflector. The particular mount construction employed utilizes a plastic block having mating parts which define a cavity from which lead wires extend and which is filled with an elastomeric polymer providing both a leak-proof seal around the lead wires as well as a more reliable barrier to moisture leakage through the mount assembly. An exterior surface of said plastic block limits insertion of the assembled lamp unit into a conventional plug-in receptacle used to supply electrical power to the lamp.
