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.
