  • the invention relates to a vehicle headlight, in particular motor vehicle headlight, comprising at least one microprojection light module according to the invention.
  • the document is from the prior art AT 514967 B1 become known, which shows a projection device of the type mentioned. It shows a projection device having a number of micro-entry optics and micro-exit optics, with aperture devices being arranged between the micro-entry and exit optics.
  • a projection device having a number of micro-entry optics and micro-exit optics, with aperture devices being arranged between the micro-entry and exit optics.
  • aperture devices being arranged between the micro-entry and exit optics.
  • the local intensity correspondingly low.
  • shading elements have been provided for this purpose in the projection lens, for example, so that illuminance is lower at these points.
  • the previous measures for darkening individual areas of the light distribution include manipulation of the projection lens or the lighting device by means of a shading element.
  • shading element darkens the shaded area strongly and a consistently uniform brightness transition to non-darkened areas could not be realized with such a shading element.
  • the area shaded in the light image was previously clearly visible to the naked eye as a local minimum of the intensity of the light distribution and thus adversely affected the overall impression of the light distribution.
  • An optically effective diaphragm edge is understood to mean a diaphragm edge which engages in the image of the light distribution for limiting the same.
  • the wording "essentially all the light emerging" means that it is intended to irradiate at least the majority of the total luminous flux that emerges from a micro-entry optic only in the associated micro-exit optics. In particular, it should be sought, no luminous flux in the adjacent micro-exit optics to radiate in a way that thereby no adverse optical effects, such as stray light, which can lead to glare, etc., result.
  • micro-entrance optics being designed in such a way and / or the micro-entry optics and the micro-exit optics being arranged relative to one another
  • additional measures such as apertures (see below) may be provided either exclusively or preferably in addition to their actual function, they still have the function that the entire luminous flux is directed precisely to the associated micro-exit optics.
  • both the focal lengths and the dimensions of the micro-optics per se are significantly lower than in a "conventional" optics.
  • the center thickness can be reduced compared to a conventional optics.
  • the overall depth of the projection device compared to a conventional optics can be significantly reduced.
  • the luminous flux can be increased or scaled, wherein an upper limit with regard to the number of micro-optics systems is limited primarily by the respectively available production methods.
  • a low beam function e.g. 200 to 400 micro-optics systems suffice or be favorable, this being neither a limiting value to describe above or below but only an exemplary number.
  • Such a light module is also scalable, ie, it is possible to combine a plurality of identical or similarly constructed light modules to form a larger overall system, for example to a vehicle headlight.
  • the lens In a conventional projection system with a projection lens, the lens has typical diameters between 60 mm and 90 mm.
  • the individual micro-optics systems In a module according to the invention, the individual micro-optics systems have typical dimensions of approximately 2 mm ⁇ 2 mm (in V and H) and a depth (in Z, see, for example, FIG FIG. 2 ) of about 6mm - 10 mm, so that in the Z direction results in a much smaller depth of a module according to the invention compared to conventional modules.
  • the light module according to the invention or the projection device can have a small overall depth and are basically freely formable, i. it is e.g. it is possible to design a first light module for generating a first partial light distribution separately from a second light module for a second partial light distribution and to make it relatively free, i. arranged vertically and / or horizontally and / or offset in depth to each other, so that design specifications can be realized easier.
  • a further advantage of a light module or a projection device according to the invention is that the exact positioning of the light source (s) with respect to the projection device is dispensed with. Precise positioning is less critical in that the distance of the illumination unit to the microlens array does not have to be exact. Now, however, since the micro-entry and micro-exit optics are already optimally matched to one another, since they form a quasi-system, an inaccurate positioning of the real light source (s) is less significant.
  • the real light sources are, for example, approximately point-like light sources such as e.g. Light-emitting diodes whose light is collimated by collimators such as Compound Parabolic Concentrators (CPC) or TIR (Total Inner Reflection) lenses.

  • the shaded area could comprise a horizontal and vertical angle of (1 ° or 2 °) to 5 ° and could be circular, for example.
  • the size of at least one shading element of a diaphragm device of the second variant deviates from the size of at least one shading element of a further diaphragm device of the second variant.
  • size is understood to mean the surface over which the respective shading element extends. Either the form can be scaled. Alternatively, it is also possible for the shapes of the shading elements to diverge, i. represent different geometric figures.
  • individual shading elements of the diaphragm device of the second variant are provided for limiting the luminous intensity of the light distribution in the segment 10 of the low-beam light distribution.

In bad weather this can be much higher than in Class C. If you place consciously behind a collimator only segment 10 lines, the affected collimator can be switched on in bad weather, but a collimator without segment 10 lines in the associated systems are switched off. This preserves the total luminous flux, but the segment 10 line is reduced in the overall light distribution. Exactly the opposite can be done with the 50L measuring point.
