Abstract

1527274 Lamps FA HOFFMEISTERLEUCHTEN KG 30 June 1976 [18 July 1975] 27342/76 Heading F4R A lamp comprises a parabolic main reflector 1 having a central opening 1e to receive the neck of a bulb 3 and a hemispherical auxiliary reflector 4 removably mounted in front of the bulb to reflect a proportion of the light back on to the main reflector, the auxiliary reflector having a central opening 4a in front of the bulb. Light emerging directly through the opening 4a is controlled by a parabolic reflective screen 4b integral with the auxiliary reflector and confocal with the main reflector. The reflector 4 is carried by a lever 6 pivoted at 8 to a circular band 5 mounted inside a cylindrical extension 1c of the main reflector, and can be pivoted downwardly against the action of a spring 7 to enable the bulb to be inserted or removed. The bulb or the auxiliary reflector may be axially adjustable to vary the shape of the light beam. In a modification the reflector 4 is mounted in the centre of a lattice or grating supported by the extension 1c. [GB1527274A]
