LED FRONT LIGHTING ARRANGEMENT

摘要

A lighting arrangement for use in automotive front lighting and a method of producing such an arrangement are described. At least one LED lighting element (40) is provided for emitting light. A collimator (10) is provided for forming an emission pattern of the emitted light, which is subsequently projected by a secondary optic arrangement (42). The collimator (10) comprises a cutoff reflector surface (18) with a front edge (30) and a back edge (32). The back edge (32) is located adjacent to the LED lighting element (40). The front edge is spaced from the back edge (32) in a depth direction X, A. The front edge (30) is arranged as a shielding edge for forming a light/dark cutoff in the emission pattern. First and second lateral reflector surfaces (26a, 26b) are arranged opposite to each other adjacent to the LED lighting element (40). The front edge (30) of the cutoff reflector surface (18) is arranged within a focal area of the secondary optic arrangement (42). For providing a beam pattern well suited for automotive front lighting, the first and second lateral reflector surfaces (26a, 26b) extend further into the depth direction A, X than the cutoff reflector surface (18).
