Abstract (en)

[origin: EP2275738A2] The element (32) has a cooling body (38) provided for delivering heat to environment, and a flange plate (36) for thermal coupling of a semiconductor light source and for fastening the element to a lighting device of a motor vehicle. A composite part is made from a cast part and an insertion part that is inserted into a casting mold during casting of the cast part, where the flange plate is provided as the cast part and the cooling body is provided as the insertion part. The cooling body is made from aluminum, copper or magnesium alloy. An independent claim is also included for a method for manufacturing a cooling element for a for semiconductor light source of a motor vehicle.
