Embodiment Construction

[0030] According to the single view, a headlight 1 is shown, which is shown simplified with dashed lines, and which has a light module 2 . The lighting module has a housing 4 made of plastic, which is designed approximately socket-shaped or approximately hollow-cylindrical. A substantially circular circuit board 6 is inserted into the housing 4 . A plurality of relatively flat LEDs 10 and further electrical components 12 are arranged on the fixed side 8 of the circuit board 6 . For simplicity, only one LED and one electrical component are provided with reference numerals. The printed circuit board 6 is arranged on the front side of the housing 4 and extends approximately transversely to the longitudinal axis of the housing 4 . In this case, the fastening side 8 points in the direction of the housing opening 14 , through which the LED 10 can then emit light. A part of the bayonet closure 16 is formed radially outside the housing 4 at the level of the printed circuit board 6 ...

Abstract

A lighting module includes a housing, in which a circuit board having at least one lighting means is arranged. A heat sink is provided to dissipate heat from the circuit board. Besides a heat sink, anadditional circuit board is provided in the housing, which is fitted with electric components for the operation of the lighting module and is arranged at a distance from the circuit board. The invention also relates to a headlight equipped with the lighting module.

Description

technical field [0001] The invention relates to a lighting module having a housing in which a circuit board with at least one lighting means is arranged, wherein the housing has a housing opening through which the radiation from the at least one lighting means It can be emitted via the housing opening, in which a heat sink is provided for conducting heat away from the circuit board. Furthermore, the invention relates to a headlight having such a lighting module. Background technique [0002] In the current state of the art, headlights for vehicles are known, wherein standards can be provided for such headlights, namely, for example, International Electrotechnical Commission (IEC) standards. For example, a standard can be provided for "exchangeable light sources (XLS)". Such light sources can be used, for example, for additional lighting functions in vehicles, for example for fog light functions. For example, the standard can relate to anti-rotation protection and referenc...
