Abstract (en)
The invention is directed to an automobile headlight comprising light sources (1), a primary optical element (2) for collimating light from the light sources (1), and a secondary optical element (3) for directing light collimated by the primary optical element (2). The primary optical element (2) comprises a body (4) comprising an exit surface (5) for letting light out of the element and comprising a collimating protrusion (6) for each light source (1). Each collimating protrusion (6) is connected to the body (4) and comprises a protrusion entry surface (7) for letting light from corresponding light source (1) in. The exit surface (5) is divided into segments (8), each corresponding to at least one collimating protrusion (6) divided into multiple subsegments. The subsegments are adapted to direct light rays passing through the corresponding collimating protrusion (6) towards the secondary optical element (3) and to decrease divergence of light rays exiting through the exit surface (5).
