Abstract (en)
[origin: EP1191278A2] The lamp light source (3) is located a the focal point of a reflector (4). The surface of the reflector is provided with prisms (10) which have the effect of defocusing the theoretical focal point by an amount (x). In consequence the prism surfaces direct a dispersed and reduced proportion of the light flux towards the cover glass (2). The glass has back reflection elements (5) and transmission points (8).
