Problems solved by technology
If the circuit carrier is thus assembled in a conventional manner with electronic components having at least two luminous surfaces, an optimal orientation of the components or of the luminous surfaces cannot be ensured
However, deviations in the orientation / position of the luminous surface can cause impermissible inaccuracies and aberrations in the light image of the motor vehicle headlight, especially when used in the motor vehicle headlight

Embodiment Construction
[0038] figure 1 A schematic diagram is shown of a fictitious (extracted from a data sheet) electronic component 1 on a fragment of a circuit carrier 2 which has been fitted with electronic components 1 (fictitious). In the present example, electronic component 1 has three luminous surfaces 3 a , 3 b and 3 c which can be actuated separately from one another. From this fictitious example, theoretical variables can be predetermined which can be compared with optically determined actual variables during the actual assembly process.
[0039]The individual positional descriptions refer to a Cartesian coordinate system consisting of an x-axis, a y-axis and a z-axis, wherein the x-axis and the y-axis are oriented parallel to the plane of the luminous area, and the z-axis protrudes into the page. The choice of the coordinate system and its location can be freely determined by a person skilled in the art, as long as an unambiguous determination of the location of the luminous areas 3a,...
