Problems solved by technology

This increases the flow resistance due to wall friction and thus requires a larger and heavier cooling device to achieve the intended cooling

Embodiment Construction

[0034] exist figure 1 A headlight 10 is shown in detail in , which has a headlight housing 12 , a lamp module 14 arranged in the headlight housing 12 and a visor 18 that allows light 16 to pass through. The light rays 16 are generated by semiconductor light sources, for example heat sources 20 to be cooled.

[0035] The light ray 16 generated by the semiconductor light source 20 is focused by the optical element 22 and optionally additionally influenced in order to obtain the desired light distribution in front of the headlight 10 . In the illustrated embodiment, the optical element 22 is a reflector. Alternatively or in addition, shuttering structures and / or lenses can be used as optical elements in order to implement reflective or projection systems and / or to generate different light distributions. The different light distributions differ, for example, in whether they have a defined light-dark boundary, and possibly also in how such a light-dark boundary is formed.

Abstract

The headlight has a cooling device (50) comprising a thermal cooling element coupled with a heat source (20). A blower generates cooling airflow (40). The cooling element and a blower housing form one-piece structural cooling element-blower housing-units (52). The blower is formed as a radial blower or a diagonal blower with a blower wheel (60) that is rotatable in the blower housing. The cooling element-blower housing-units are formed as stators. The heat source is arranged on an outer wall of the cooling element-blower housing-units.

Description

technical field [0001] The invention relates to a headlight for a motor vehicle. Such a headlight has a heat source to be cooled and a cooling device with a cooling body thermally coupled to the heat source and a fan with a fan housing which generates an air flow that cools the cooling body. Background technique [0002] Such headlights are supplied by the applicant as LED headlights (LED=Light Emitting Diode) for the Audi R8 and are therefore known on the market. In this headlamp, the LED configuration is the heat source. [0003] At present, semiconductor light sources are more and more widely used in lighting devices of motor vehicles. Since the application was temporarily limited to signal lights such as brake lights and turn signals, semiconductor light sources are now also used in headlight functions, ie for lighting the automotive environment. [0004] Unlike halogen or gas discharge lamps, LEDs emit cold light. The radiation itself therefore does not contain a th...
