the invention relates to a novel projector which has an asymmetrical illumination characteristic , and a clear light - dark limit , and uses almost the entire radiation power outputted from the semiconductor light source . to this end , the projector consists of a field of individual semiconductor light sources which are provided with optical elements having a novel form . said optical elements have as flat a form as possible , such that the light admission inlet of the optical element has an elongated , essentially rectangular form . furthermore , the optical elements comprise a central region , perpendicular to the light admission surface , the projection of said central region into a two - dimensional plane corresponding to a cylindrical two - dimensional cartesian oval . according to the invention , in order to better use the light emitted from the semiconductor light source , the light emergence surface of the optical element , in the form of a cartesian oval , is combined with a parabolic reflector .
