Abstract
An improved sealing means is provided for a sealed prefocused light source mount for a parabolic aluminized reflector (PAR) lamp and, in particular, to improved leak-proof sealing means for an all-plastic lamp or a lamp comprising a plastic reflector. The improved mount construction 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.
