Abstract
The invention concerns a lamp having a reflector, a glass lid and a filament which is supported by supply wires. The supply wires pass from the interior of the lamp to the outside through the connecting area between the reflector and the glass lid. The reflector is thus almost 100 percent effective because there is no space required for a material collection marking a passage of supply wires or a socket for receiving a bulb. The light performance of the lamp is thus an optimum.

A lamp for use in an enclosed room, said lamp comprising:
- a reflector having a peripheral rim, an interior reflector surface and an exterior reflector surface;
- a glass lid having a peripheral flange extending over said reflector peripheral rim;
- a filament supported by at least two supply leads;
- said reflector peripheral rim and said glass lid peripheral flange being sealingly interconnected by a sealant along a fixing seam to thereby define an interior region of said lamp;
- each said supply lead being guided from a position adjacent said reflector exterior surface through a peripheral connection point between said reflector rim and said glass lid flange into said lamp interior region;
- and
- wherein said two supply leads are positioned parallel and juxtaposed to one another and secured in a clip-like formation over said reflector rim, said clip-like formation including said parallel, juxtaposed leads being held by an electrically insulated connecting element adjacent said reflector exterior surface, extending over said reflector rim, and along said reflector interior surface.
