ABSTRACT:
The electric reflector lamp has a light source in an envelope with a seal. The seal has a projection against which a plate rests, the plate having a side which faces the light source. The seal is secured in the neck of a reflector body by means of cement which is present at a side of the plate which faces away from the light source. Thereby, an open passage to the beam-shaping portion of the reflector body exists allowing volatile substances released by the cement to escape when the reflector body is closed by means of a cover.
