ABSTRACT:
An encapsulated lamp assembly for use under submerged conditions and in environments where the lamp may be subjected to extreme temperature variations and corrosive conditions, which includes a bulb and base unit with single or multiple filaments and leads cooperating with the filament busses. The leads are typically soldered to the busses, and the entire unit is sprayed, brushed or dipped in a silicone composition to provide a thin film of protective silicone material on the outside and on the junction between the leads and the busses. A rubber boot is positioned on the leads to insure a thick coating on the lead-bus junctions, and the lamp assembly can be fitted to any conventional bracket mechanism.
