ABSTRACT:
A lamp assembly, particularly intended for use on a motor vehicle, comprises a reflector which receives a light bulb, and a first lens element which overlies the reflector and which has formed on one surface thereof a multiplicity of individual lenses. A baffle is secured to the opposite surface of the first lens element, and includes a multiplicity of light-transmitting portions each of which is disposed on the optical axis of a respective one of the individual lenses and whose extent is limited to that necessary to transmit substantially the whole of a pencil of light rays which is focussed by the respective individual lens. The remainder of the baffle is light-obstructing. A second lens element overlies the first lens element and the baffle, and also includes a multiplicity of individual lenses which are in no particular registration with the individual lenses of the first lens element. The first lens element can be shaped suitably for the securement thereto of the baffle, which is advantageously made from planar material, whereas the second lens element can be shaped according to the desired external configuration of the lamps assembly.
