Abstract
A lighting arrangement for use in automotive front lighting and a method of producing such an arrangement are described. At least one LED lighting elementis provided for emitting light. A collimatoris provided for forming an emission pattern of the emitted light, which is subsequently projected by a secondary optic arrangement. The collimatorcomprises a cutoff reflector surfacewith a front edgeand a back edge. The back edgeis located adjacent to the LED lighting element. The front edge is spaced from the back edgein a depth direction X, A. The front edgeis arranged as a shielding edge for forming a light/dark cutoff in the emission pattern. First and second lateral reflector surfacesare arranged opposite to each other adjacent to the LED lighting element. The front edgeof the cutoff reflector surfaceis arranged within a focal area of the secondary optic arrangement. For providing a beam pattern well suited for automotive front lighting, the first and second lateral reflector surfacesextend further into the depth direction A, X than the cutoff reflector surface
