Abstract

1444597 Lamps DUCELLIER & CIE 24 Oct 1973 [26 Oct 1972] 49499/73 Heading F4R A lamp, in particular a vehicle fog lamp, comprises a light source 2, a ribbed lens 3 and a reflector 4, the reflector being in the form of two paraboloid sections 5, 6 having respective axes 5a, 6a which are mutually inclined and which intersect at the centre of the light source, and the two inclined light beams produced by the reflector being transformed by the lens into a single spread beam of uniform intensity.
