Abstract

1424360 Lamps ROTAFLEX (GREAT BRITAIN) Ltd 11 May 1973 [22 May 1972] 23943/72 Heading F4R A spotlight comprises a parabolic reflector 1, a lamp holder 3 extending transversely of the reflector and supporting a bulb L, and a further reflector 12 disposed in front of the bulb and having a reflective rear surface for reflecting light from the bulb on to the reflector 1. The lamp holder is rotatable about its axis by means of a thumbscrew 8 slidable in a slot (9) in a cover member 4 secured to the reflector 1, the rotation enabling rough focussing of a general service filament lamp bulb. The reflecter 12 may have a part spherical rear surface 13 and be held to the reflector 1 by a thumbscrew 14 clamped to cover member 4.
