Abstract

A cup-shaped reflector has a larger open end and a smaller open end. A diffuser glass closes off the larger open end. A lamp is comprised of a lamp bulb having a fused, squashed-flat rear portion hermetically sealing the interior of the bulb, with a plurality of lamp electrodes passing through the squashed-flat rear portion of the lamp bulb and embedded within the material of the squashed-flat rear portion of the lamp bulb. A plurality of lugs is provided, each connected to one of the lamp electrodes at the rear of the lamp, in electrically conductive engagement with the electrodes. A mounting arrangement mounts the lamp bulb on the reflector in the region of the smaller open end of the reflector with at least part of the lamp bulb projecting forwardly into the interior of the reflector.
