Description

Lighting module, vehicle lamp and motor vehicle
Technical Field
The present utility model relates to a lighting module, a vehicle lamp comprising such a lighting module, and a motor vehicle employing such a vehicle lamp.
Background
Automotive vehicle lamps typically include a lighting module, such as a tail lamp, with a fog light module mounted therein. Fog lamp modules typically include optical elements such as light sources, collimators, and heat sinks. One type of heat sink is injection molded from a thermally conductive plastic and includes a plurality of fins that can be assembled to the light source to dissipate heat from the light source. The heat conducting surface of such an injection molded heat sink (i.e., the surface in contact with the heat radiating surface of the light source) is generally not sufficiently flat and therefore cannot be closely adhered to the heat radiating surface of the light source. In order to improve the heat conduction efficiency between the heat sink and the light source, a heat-conducting glue needs to be coated between the contact surfaces of the heat sink and the light source. In addition, the existing fog lamp module generally exposes the radiating fins outside the shell of the automobile lamp so as to improve the radiating efficiency, and therefore, an additional waterproof rubber ring is required to ensure the tightness of the automobile lamp.
It is therefore desirable to design a lighting device that is simpler and less costly to construct, while meeting the heat dissipation requirements of the lighting device, such as a fog lamp module.
