ABSTRACT:
To prevent direct radiation from a halogen incandescent lamp-reflector un while permitting easy removal of the unit by grasping a holding element (8) for a radiation-preventing cap (6'), the holding element is made in the form of a flat sheet-metal strip (8) spanning the rim of the reflector (5). The flat sheet-metal element has a black surface finish and is secured to the reflector, for example by projecting flaps (10) engaging through slits (13) formed in the reflector, and twisted to secure the strip in position. The cap, likewise,is formed with slits (11, 11') engaged by projections (9, 12) and likewise held in position by twisting a central one (12) of the projections, the other projections preventing rotation of the cap with respect to the holding strip. The arrangement permits ready placement or exchange of the lamp from a fitting by grasping the holding strip, without thereby causing change in the optical characteristics of the halogen incandescent bulb (4)-reflector (5) combination.
