Patent ID: 8436394

Claim:
A luminescence diode chip comprising: a semiconductor layer sequence having an active layer that generates electromagnetic radiation, and a first electrical connection layer which touches and makes electrically conductive contact with the semiconductor layer sequence with a plurality of contact areas, wherein 1) an inhomogeneous current density distribution is set in the semiconductor layer sequence in a targeted manner by an inhomogeneous distribution of an area density of the contact areas along a main plane of extent of the semiconductor layer sequence such that a first region of a main coupling-out area of the semiconductor layer sequence or of the luminescence diode chip has an irradiance or illuminance at least three times as high as that of at least one second region of the main coupling-out area of the semiconductor layer sequence or of the luminescence diode chip; and 2) a radiation cone emitted by the luminescence diode chip has a radiance distribution corresponding to a radiance distribution for a low-beam light of a motor vehicle.
