Abstract
To permit introduction of a halogen incandescent lamp into a reflector, in ealed relationship thereto, a plastic end portion (2c) of the base (2) of the lamp is secured to a metal sleeve, for example of steel, which is telescopically connected to an adjustment cap (2a) in which the bulb (1) is seated. After adjustment of the position of the bulb, so that the filaments will emit light in a predetermined pattern with respect to the base, the adjustment cap and the sleeve are welded together. The plastic portion includes a groove (9) in which a sealing ring (10) for example of silicone rubber is placed, the plastic element including therebeyond a positioning or seating flange (11). The plastic end portion, thus, can readily be assembled with a glass reflector, the sealing ring (10) providing for a moisture tight seal against, for example, a glass reflector.
