Patent ID: 8870426

Claim:
An illumination unit for vehicle headlights, the illumination unit comprising: a light-emitting diode device, a housing and an assembly board on which components of an operating circuit for operating the light-emitting diode device are arranged, wherein the housing is made of plastic and a section of the housing is embodied as connector comprising electrical terminals which are electrically connected to metal pins serving as electrical contact pins and protruding through drilled holes in the assembly board, wherein the housing and the assembly board define an interior space, wherein the assembly board has at least one electrically conductive inner layer that is connected to a ground reference potential of the operating circuit and on its surface the assembly board has at least one electrical contact surface which is contacted with at least one electrically conductive inner layer by means of one of the metal pins passing through the electrical contact surface and the electrically conductive inner layer, and the housing has an electromagnetic shielding structure configured to provide electromagnetic shielding of the interior space, wherein the electromagnetic shielding structure comprises a metallization of the housing which connected to the at least one electrical contact surface.
