Embodiment Construction

[0018] exist figure 1 1 denotes a circuit board which has three mutually identical groups A, B and C of contact pads 2 . as in figure 1 It can be clearly seen in the figure that the contact pads 2 of the respective groups A, B and C are equipped with LEDs 3 , wherein in group B for example a daylight function can be realized, in group A a low beam function can be realized and in group C The high beam function can be realized in the middle. Depending on the different configuration of the LEDs in the individual groups A, B and C and the associated different light functions, it is also necessary to use reflectors A', B' and C' matched to the specific light function. In order to eliminate confusion here as described above, fastening means A'', B'' and C'' for the reflectors A', B' and C' are now provided on the circuit board 1, said fastening means in which The geometry or arrangement corresponds to the geometry or arrangement of the fastening pins 4 of the reflectors A', B' an...

Abstract

The invention relates to a method for producing a lighting unit of a vehicle headlight, comprising the following steps: provision of a printed circuit board (1) comprising a plurality of groups (A, B, C) of contact pads (2) for contacting LEDs (3), population of contact pads (2) in the groups (A, B, C) with LEDs (3), wherein the contact pads (2) to be populated are selected according to a desired light function of the respective group (A, B, C), and provision of securing means (A″, B″, C″) for reflectors (A′, B′, C′) on the printed circuit board (1), wherein each securing means (A″, B″, C″) is specifically designed for a reflector (A′, B′, C′) that is adapted to the light function of the respective group (A, B, C).

Description

technical field [0001] The invention relates to a method for producing a lamp unit for a vehicle headlight and a lamp unit produced according to this method. Background technique [0002] Modern vehicle headlights not only provide various complex and efficient light functions, but are also increasingly integrated into the design of the corresponding vehicle and both with regard to the air resistance of the vehicle and also with regard to safety-related aspects, e.g. Pedestrian protection has been optimized. However, the desirable features and functions of modern vehicle headlights are accompanied by difficulties in the standardization of the corresponding components, so that achieving a greater number of components and thus economies of scale in costs becomes increasingly difficult. more and more difficult. This is particularly disadvantageous for vehicles in the middle to low price segment. Contents of the invention [0003] It is therefore the object of the present in...
