Definitions

  • the invention relates to a lighting device for a motor vehicle.
  • arrays of multiple light sources are increasingly being used, which generate a predetermined light distribution in the far field of the motor vehicle. Due to the technical structure of such arrays, the individual light sources can not be placed arbitrarily close to each other. In particular, requirements with regard to the cooling of the individual light sources should be taken into account, especially if the light sources are semiconductor diodes. There are therefore edges around the light sources, which cause unwanted brightness fluctuations or dimming in the light distribution generated by the lighting device.
  • each light source of the array with an optical attachment to thereby close gaps between the light sources by optical magnification of the light sources.
  • image the individual light sources in a blurred manner, so that dark edge zones in the light distribution generated by the lighting device are blurred and thereby brightened.
  • attachment optics has the disadvantage that due to the very short focal lengths of the lenses used for this purpose, the illumination device is sensitive to tolerances, so that their adjustment is associated with high costs and high costs. In addition, due to the large number of transition regions between the individual attachment optics, high losses and disruptive side effects occur.
  • the aforementioned blurred image of individual light sources can only partially reduce brightness variations in the generated light distribution, and further destroys large gradients in light distribution that are desirable for particular light patterns.

In addition, a disturbing crosstalk between individual light sources is avoided, as is the case with front optics. This is because the secondary optics are shared by all light sources. Due to the relatively large secondary optics, high efficiency can be achieved with few losses. Furthermore, the individual light sources of the array no longer have to be packed tightly together, which simplifies the cooling of these light sources and reduces the technical complexity in the production of the array. Furthermore, a process-intensive assembly of many individual primary optics becomes superfluous.

  • a combination of homogenization and color mixing is used, for example, to produce homogeneously luminous, color-tunable light surfaces.
