Abstract (en)
The present invention relates to a lighting module for an automotive vehicle. The lighting module comprises a light source (10) for producing a light beam. Additionally, the lighting module includes a heat exchange system (100) for transferring heat away from the light source (10). The heat exchange system (100) is provided with a heat sink plate (11) and a plurality of heat transfer airfoils. The plurality of heat transfer airfoils forms two parts with. a plurality of non-anodized heat transfer airfoils (14) and a pair of anodized heat transfer airfoils (12). The airfoils are provided such that the pair of anodized heat transfer airfoils (12) is at peripheral portion encompassing the plurality of non-anodized airfoils (14) of the heat exchange system (100). The plurality of non-anodized airfoils (14) and pair of anodized heat transfer airfoils (12) are thermally connected to the heat sink plate (11) and transfer the heat away from the system.
