Definitions
- the invention relates to a headlight module for motor vehicles with at least one light source, which in the beam path at least one deflection mirror, a
- Subsequent micromirror array and a lens are arranged downstream, wherein the light emitted by the at least one light source is reflected via the deflection mirror on the controlled by a control micro-mirror array and the light image generated on this is projected via the lens as a light image in the traffic area.
- Headlamp modules of this type are known and described for example in DE 10 2014 219 799 AI or JP 2015138763 A.
- An object of the invention is to provide a headlamp module or a headlamp that meets this need.
- lens and mirror are integrally formed as a lens / mirror block, which has a lens area and a mirror area.
- Another advantage of the invention is the shortened tolerance chain due to the reduced number of individual components, whereby the
- the lens is subordinated at least one further optics.
- a further expedient embodiment is characterized in that a radiation diaphragm coating is applied to the surface of the lens / mirror block facing the at least one light source on a passage region surrounding the lens region.
- the at least one light source at least one laser diode / LED and one of these downstream focusing lens.
- the invention also includes a headlamp having at least one headlamp module as characterized above.
- FIG. 1 is a schematic perspective view of the arrangement of a light source, a deflection mirror, a micromirror array and a lens according to the prior art
- FIG. 2 shows the structure of a headlamp module according to the schematic diagram of FIG. 1, partially in section,
- 3 is a schematic perspective view of the arrangement of a light source, a deflection mirror, a micromirror array and a lens according to the invention
- 4 is a perspective view of an inventive design of mirror and lens as a lens / mirror block
- Fig. 5 seen in a perspective view obliquely from the front a
- Headlamp module with a lens / mirror block covered by an aperture
- FIG. 6 the headlight module of FIG. 5, but partially cut and
- Fig. 7 is a view similar to Fig. 6, a headlamp module according to the invention with another embodiment of the aperture.
- Headlight module 1 or a headlamp unit in also with respect to the beam path 15 greatly simplified representation.
- required parts such as a power supply, an electronic control, brackets, other optical elements, etc. are also omitted for simplicity in the drawing.
- a light source 2 which here consists of three laser diodes or LED chips LED1, LED2, LED3 with downstream focusing lenses LI, L2, L3 (see also Fig. 3), sends the light emitted by it via a deflection mirror 3 on the active Area of a
- Micro-mirror arrays 4 which are controlled intelligently, generate an image that is projected via a lens 5 as a light image in the traffic space generally located in front of a motor vehicle.
- Fig. 2 shows the basic structure shown in Fig. 1 in use in a conventional technical embodiment, wherein the same elements with the same
- the light source 2 which can consist of individual light sources, such as LED chips, also here in the direction of emission of the headlamp module in front mirror 3, the mirrored surface is concavely curved here again lying back and above the light source 2 the
- Micro-mirror array 4 In front of the micromirror array 4, the lens 5, located above the mirror 3, is arranged here as a biconvex glass body. Furthermore, one recognizes a main body 6 of the module 1, in which the micromirror array 4 and a circuit board 7 of FIG Light sources are stored and provides for the necessary stability of the arrangement and possibly also for cooling. For the mirror 3 is its own
- Mirror holder 8 is provided and the lens 5 is held in a corresponding version 9.
- Headlight module 1 shown, again like reference numerals for the same or similar parts are used. It is essential here that the lens and mirror are integrally formed as lenses / mirror block 10, which has a lens area 10-3 and a mirror area 10-5.
- the lens / mirror block 10 is made in one piece from glass.
- glass is used, this term used in the description and the claims being understood to mean a material which has the optical properties of a glass in the sense of classical optics but is not necessarily a glass in the physical sense must
- Lens material therefore does not have to be amorphous, it could also be crystalline or a plastic, it must be transparent in any case and have refractive properties.
- optical glass is preferred in the conventional sense because it best ensures high accuracy of the lens and heat resistance.
- the lens region 10-3 has a radiation diaphragm coating 12, which leaves only a circular passage region 13 for light, in order to avoid the false light that reduces the contrast.
- the jet diaphragm coating can consist of a visible light-absorbing material which is applied, for example, by means of a two-component injection molding technique or another coating process.
- the facing surface of the lens / mirror block 10 which may also be referred to as the inside, formed substantially concave, whereas the opposite surface or
- lighting requirements also different, e.g. plan, convex or concave. This depends in particular on further, possibly used in the module 1
- Optical elements from.
- Fig. 5 and 6 show the basic structure shown in Fig. 3 in application in a technical embodiment of a headlamp module 1 according to the invention, wherein like elements are provided with the same reference numerals as in the preceding figures and not necessarily described again for simplicity.
- the lens / mirror block 10 in which the entire rear side, with the exception of the passage region 13, is provided with a reflective coating 11, for example an Ag coating.
- the further upwardly extending mirror coating 11 thus serves as a radiation aperture coating.
- Fig. 5 is drawn so that you can see the back of the lens / mirror block 10 from the front.
- Lens / mirror block 10 all around, i. side and top and bottom, covering and
- the embodiment according to FIG. 7 differs from that according to FIGS. 5 and 6 in that the diaphragm 14 here also covers the mirror region 10-5 of the lens / mirror block 10 at the front, so that only the lens region 10-3 is not covered, which is necessary because of the light emission.
- the lens or lens area 10-3 may be either the front end of the lens or lens area 10-3
- Headlamps form or it can also be protected by a cover glass to the front.
- the lens can also be followed by an additional, optionally integrated in the cover glass optics and it can also be between the light source and
- Lens / mirror block be arranged more optical elements. Outside of the areas of the lens / mirror block 10 which are relevant for photometry, this design specification or mechanical requirements, for example with respect to the holder in the module, can be correspondingly freely designed.
