Definitions
- the invention relates to a projection device for a motor vehicle headlight, wherein the projection device is arranged for imaging light of at least one projection device associated light source in an area in front of a motor vehicle in Porm at least one light distribution, wherein the projection device has an entrance optics, which are preferably arranged in an array having exit optics, which are preferably arranged in an array, wherein each micro entrance optics is assigned exactly one micro exit optics, wherein the micro entrance optics are configured and / or the micro entrance optics and the micro exit optics are arranged in such a way that substantially all of the light emerging from a micro-entrance optics enters only into the associated micro-exit optics, and wherein the light preformed by the micro-entry optics from the micro-exit optics in a range before the motor vehicle is shown as at least one light distribution, wherein between the entrance optics and the exit optics at least one translucent carrier is arranged, wherein the at least one carrier has at least a first diaphragm device, wherein the first di
- the invention relates to a microprojection light module for a motor vehicle headlight, comprising at least one projection device according to the invention, a vehicle headlight, in particular
- Motor vehicle headlight comprising at least one microprojection light module according to the invention and a vehicle, in particular a motor vehicle, with at least one vehicle headlight according to the invention.
- the invention relates to a method for producing a fiction, contemporary projection device for a motor vehicle headlight. Furthermore, the invention relates to a method for producing a fiction, contemporary projection device for a motor vehicle headlight.
- the heat input into the projection device has a significant influence on their optical behavior.
- heat input of a light source as well as by light absorption within the respective optics or diaphragm device they can be heated so far that the projection device causes aberrations.
- optics and optionally provided diaphragm devices may have different thermal expansion coefficients due to material differences and expand differently. This problem is even more pronounced when transparent elements such as the entrance optics and the exit optics as well as absorbing elements such as optionally provided aperture devices reach different temperature levels when heat is applied.
- the opaque coating consists of at least two superimposed sublayers, namely a reflective metallic first sub-layer and a substantially consisting of black light-absorbing paint second sub-layer, wherein the first sub-layer between the Entry optics and the second sub-layer is arranged.
- the actual heat input into the diaphragm device depends in practice on the luminous flux as well as the light distribution to be formed. For example, in the case of a low-beam light distribution, approximately 40% of the light irradiated through the entrance optics is shadowed by means of the diaphragm device. Reflection on the first part layer thus significantly reduces the heat input into the diaphragm device. This reflected light also causes no disturbing stray light.
- a downstream black second sub-layer achieves a further effect which leads to the reduction of aberrations.
- a metallic first sub-layer without a successor layer would have the consequence that in the diaphragm device fed back scattered light is reflected back to the front over the reflective layer. This would result in unwanted crosstalk in a downstream optics.
- the light-absorbing second sub-layer of this feedback scattered light can be absorbed and thus crosstalk can be avoided. Since the scattered light represents only a small proportion of the total luminous flux, the heat input thereby introduced into the diaphragm device is negligible.
- the metallized layer also increases the opacity of the diaphragm device.
- a second beam stop can be provided, which can be provided to eliminate optical errors.
- a substantially opaque coating is meant a coating applied thereto Coating incident light is reduced at least to an extent so that no passage of light is visible to the human eye.
- micro-entrance optics being designed in this 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 with "conventional" optics As a result, the overall depth of the projection device can be significantly reduced in comparison with conventional optics.
- 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 for example, 200 to 400 micro-optical systems may suffice or be favorable, although this is not intended to describe a limiting value up or down but merely an exemplary number.
- micro-optics thus also allows design options that are not available in a conventional optics.
- Individual micro-optics can have different focal lengths, whereby additional degrees of freedom in the design of the light distribution can be obtained.
- Some micro-optics can be designed as astigmatic lenses, so that the incident luminous flux is influenced differently, for example, in the horizontal and vertical directions.
- individual micro-optics for example, can contribute to changing the maximum value of the irradiance in a light distribution, other micro-optics can in turn be used to control the horizontal extent of the light distribution.
- Such a projection device or light module is also scalable, that is, multiple identical or similarly constructed light modules can be made into a larger overall system, e.g. be assembled to a vehicle headlight.
- the lens has typical diameters between 60 mm and 90 mm.
- the individual micro-optics systems have typical dimensions of approximately 2 mm ⁇ 2 mm (in V and H) and a depth (in Z, see, eg, FIG. 1) of approximately 6 mm-10 mm, so that a significantly lower depth of a module according to the invention compared to conventional modules results.
- the projection device according to the invention has 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 projection module is that the exact positioning of the light source (s) with respect to the projection device is eliminated. Exact positioning is only of secondary importance insofar as the at least one light source may possibly illuminate an entire array of micro-entrance optics, all of which produce substantially the same light image. In other words, this means nothing else than that the "actual" light source is formed by the real light source (s) and the array of micro-entry optics, this "actual” light source then illuminating the micro-exit optics and, where appropriate, the associated apertures. 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 punctiform light sources such as light-emitting diodes whose light is collimated by collimators such as Compound Parabolic Concentrators (CPC) or TIR (Total Internal Reflection) lenses.
- CPC Compound Parabolic Concentrators
- TIR Total Internal Reflection
- the projection device according to the invention can be set up to produce a wide variety of light distributions.

- LEDs can be used as the light source in the invention, wherein the radiated light cone of the LED can be directed substantially parallel by means of collimator optics.
