Abstract
The disclosure relates to an optical element for a lighting device, the optical element comprising a body capable of conducting light, wherein the body comprises: a light incoupling surface; a light outcoupling surface; and side faces situated opposite to each other and extending from the light incoupling surface to the light outcoupling surface; wherein at least one of the side faces has an aspherical shape at least in sections. The at least one side face having the aspherical shape is capable of focussing light originating from a first point on the light incoupling surface to a second point on the light outcoupling surface by internal reflection at least in the sections. The optical element may serve in the lighting device as a precollimator with configurable intensity distribution of the precollimated light. The shape of the optical element may be easily determined for various dimensions of the optical element. The disclosure further relates to a lighting device and a method for production of a lighting device.
