Definitions

  • the invention relates to a light module such as can be used in particular in motor vehicle headlights.
  • a light module is understood to mean the actual light-emitting unit of a headlamp which emits the desired light distribution.
  • this should have certain, generally legally prescribed, characteristic intensity profiles.
  • dimmed light distributions dipped beam, fog light
  • high beam light distributions are to be generated.
  • So-called partial high beam distributions are also desired, in which certain areas of the emitted light distribution are specifically darkened.
  • the desired beam light distribution therefore usually has a certain structure of light and dark areas (e.g. a light-dark border or a masked area), which should be achieved as precisely and reproducibly as possible.
  • the known light modules usually include a light source for emitting light, primary optics for shaping a desired intermediate light distribution from the light from the light source, as well as secondary optics which are set up to project the intermediate light distribution generated by the primary optics as an emitted light distribution into the area in front of the light module.
  • Light modules are known which have a lens device which is set up to shape a desired light distribution.
  • the arrangement of the primary optics relative to the light source has an influence on the portion of the light from the light source that is captured by the primary optics and therefore determines the efficiency of the light module.
  • the arrangement of the secondary optics relative to the primary optics and / or the light source influences whether the desired light-dark transitions are reproduced with sufficient contrast.
  • lenses or other transparent optical elements are usually made of a light-refractive material. Such materials mostly have dispersion properties, ie they show a dependence of the refractive index on the wavelength of the light. As a rule, there is stronger refraction for light in the blue wavelength spectrum than for light in the red wavelength spectrum. When using lenses in light modules, this can lead to the emission of light distribution showing undesirable color effects.
  • the mentioned structures of the emitted light distribution from light and dark areas (for example light-dark border of the low beam, masked areas of the partial high beam) can show colored edges or color fringes.
  • This dispersion effect is particularly noticeable in lens devices which are used for projection or for imaging (for example through primary optics generated) intermediate light distribution serve as emission light distribution in the area in front of the light module, ie with a lens device acting as a secondary optics.
  • the lens devices mentioned for example secondary optics
  • the lens device is mostly held in a lens holder which is fixed in the light module by screwing, clamping or reshaping the lens holder.
  • One problem then is that loosening the fastening can be problematic or that after loosening the fastening, renewed fastening is only possible with less positional accuracy (e.g. because screw sockets or threads are expanded by repeated screwing in and unscrewing).
  • plastic parts are to be used, since these are softer than metals and e.g. Deformations can occur in threads or screw sockets. Nevertheless, the use of plastic parts is increasingly desirable, since such components can be produced comparatively easily and inexpensively (e.g. by injection molding). In addition, plastic parts can be designed as design parts, which is particularly desirable for lens devices and lens holders that are visible from outside the light module.
  • the invention is based on the object at a Light module to enable a precisely positionable and at the same time easily detachable fastening of the lens device relative to other optical components. This should be particularly advantageous in the case of plastic parts.
  • a light module in particular for motor vehicle headlights, which is set up to emit light with an emitted light distribution in a main emission direction of the light module.
  • the light module has a lens device, for example a collecting lens, for shaping a desired light distribution.
  • This light distribution can be the final emission light distribution of the light module or an intermediate light distribution.
  • the lens device is guided into a desired position on the light module with precise positioning by means of a positioning device and is fastened there by means of a fastening device.
  • the guidance is positionally accurate insofar as the spatial position of the lens device relative to other components of the light module can be precisely determined with respect to all three spatial directions.
  • the fastening device serves to connect the lens device to one or more other components of the light module in the position specified by the positioning device.
  • the positioning device has at least one dowel pin and an associated dowel socket, the dowel pin engaging in the dowel socket for positioning the lens device.
  • the fastening device has at least one fastening projection which is designed differently from the dowel pin, an associated fastening recess which is from the dowel socket is designed differently, as well as an associated fastening means. To fasten the lens device, the fastening projection engages in the fastening recess and is fixed with the fastening means.
  • the positioning device serves to enable an axial adjustment of the lens device in the light module.
  • the dowel pin extends along a guide direction and can be displaced without play along this guide direction in the dowel bush. This enables a precise setting of the distance between the lens device and other optically functional components of the light module. However, a lateral positioning inaccuracy is avoided.
  • the guide is backlash-free insofar as a desired quality of fit is achieved, for example that the parts can be moved relative to one another without noticeable play, as is customary for gearwheels or clutches. A fit is also conceivable such that parts can just barely be moved against one another by hand, as is usual for guides on machine tools or adjusting rings.
  • the guide direction is selected to be essentially parallel to the main emission direction of the light module, so that no lateral positioning inaccuracy is caused by the axial displacement of the lens device.
  • the fastening projection is preferably also designed like a pin.
  • the fastening recess can be designed in the manner of a socket.
  • the invention is based on the idea of achieving a functional separation between positioning and fastening.
  • the positioning device is shaped with high precision.
  • the alignment pin essentially engages here backlash-free into the fitting socket.
  • Dowel pin and dowel bush have a highly precise fit, preferably in such a way that the parts can just about be moved against one another by hand. In the case of the fastening device, however, lower demands can be placed on the fit.
  • the decisive factor here is that a fastening is possible, which in particular is also designed to be detachable. Even if the fastening device loses its accuracy of fit as a result of multiple loosening and re-fastening (for example, by widening threads), the positioning device ensures the exact positioning.
  • the configuration according to the invention allows a precisely fitting arrangement, especially when essential components of the light module are made of plastic. This is often desirable because it enables the parts to be manufactured particularly cheaply and to be designed as a design part.
  • Parts of the lens device for example a lens holder of the lens device, in particular a fastening projection and / or fastening recess and / or the fastening means are preferably formed from plastic.
  • a plastic suitable for the injection molding process is preferably used here, for example PMMA, polycarbonate, polyimide or the like.
  • the solution according to the invention enables multiple fastening and loosening of the lens device. Even if the fastening device loses precision due to deformation of the fitting parts (for example due to characteristic creeping processes of plastic material under pressure in threads), precise positioning is ensured by the positioning device.
  • the light module usually includes further components, as explained at the beginning of the known light modules.
  • a light source for emitting light is provided, the lens device being set up to shape the light emitted by the light source directly or indirectly (i.e. via a further optical device) into a desired light distribution, for example to focus or collimate it.
  • the light module can also have primary optics for forming a desired intermediate light distribution from the light from the light source.
  • secondary optics are then provided, which are set up to project or map the light distribution generated by the primary optics as an emitted light distribution into the area in front of the light module.
  • the lens device mentioned forms the secondary optics in particular.
  • the dowel pin and the fastening projection are preferably arranged directly or indirectly (i.e. via a further component, e.g. carrier) on the lens device.
  • the fitting socket and the fastening recess can then be arranged on another section of the light module, for example on a light source device, a carrier element or a primary optics device with respect to which the lens device is to be positioned and fastened.
  • the fitting socket can be arranged on the lens device and the associated dowel pin can be arranged on another component of the light module.
  • the fastening recess can be arranged on the lens device and the associated fastening projection can be arranged on another component of the light module.
  • the lens device has the alignment pin and the fastening recess, whereas the alignment socket and Fastening projection are provided on another component of the light module.
  • the fitting bushing can be designed as a sintered bushing.
  • the fitting bushing is made from a metallic sintered material. This sintered bush can for example be cast into a plastic component.
  • the dowel pin can be designed as a turned metal pin. This also improves the positional accuracy, since more precise fits can be achieved with metal parts than with plastic parts.
  • the rotated metal pin can for example be cast into a plastic part. For this purpose, after a first manufacturing step, this plastic part can have a pin recess into which the metal pin is cast in a second manufacturing step.
  • the fastening projection is preferably designed as a pin extending along a connecting direction.
  • this pin has a fixing slot which extends along the connection direction and into which the associated fastening means can engage.
  • the associated fastening means is designed in particular as a fixing screw which can be screwed into the fixing slot of the pin.
  • the fixing screw is preferably screwed into the fixing slot in a direction perpendicular to the connection direction in such a way that the pin-like fastening projection is fixed in the fastening recess.
  • the fastening recess is designed in particular in the manner of a socket in which the fastening projection can be displaced along the connecting direction mentioned, the fastening recess having a screw hole running perpendicular to the connection direction through which the fixing screw can be screwed into the fixing slot. Since the fixing slot extends along the connection direction, the fastening projection can be pushed into the fastening recess to a desired depth and can be fastened by screwing in the fixing screw.
  • the pin-like fastening projection is designed to be slotted in such a way that the pin spreads open by screwing the fixing screw into the fixing slot.
  • a form-fitting connection can be established in sections between the fastening projection and the fastening recess. This configuration is particularly advantageous in the case of plastic components, since with such materials typical deformations due to creep processes can occur in the material under force loading.
  • the lens device has a lens holder in which an optically effective lens element (for example, a converging lens) is held.
  • an optically effective lens element for example, a converging lens
  • Components of the fastening device and the positioning device are preferably arranged on the lens holder.
  • the dowel pin and / or the fastening projection is provided on the lens holder.
  • the fitting bushing and / or the fastening recess can also be arranged on the lens holder.
  • the light module can also have a holding frame, via which the lens device is fixed in the light module.
  • the section of the lens holder facing away from the lens element has a connecting section which can be joined to a corresponding connecting section of the holding frame.
  • Dowel pin, dowel socket or fastening projection and fastening recess are arranged on the connecting sections of the holding frame and lens holder.
  • the guide pin and the fastening projection preferably extend parallel to one another. To that extent said guiding direction and said connecting direction run essentially parallel. This enables an axial adjustment and positionally accurate axial fastening of the lens device.
  • the dowel pin engages in the dowel socket without fastening.
  • the positioning device and the fastening device are then functionally completely separated from one another. The positioning function is not impaired by multiple fastening and loosening of the fastening device.
  • Figure 1 shows a modular light module 10, which is made up of pre-assembled units.
  • the main components of the light module 10 are: a light source unit 12, a primary optics unit 14, a holding frame 16 and a secondary optics unit 18, which forms a lens device in the present sense.
  • These structural units are shown in accordance with Figure 1 Imaged lined up along an assembly direction 20 and for the final assembly of the light module 10 they are moved towards one another essentially along the assembly direction 20 and assembled.
  • the light source unit 12 comprises a printed circuit board 22, which forms a front side of the light source unit 12 facing the primary optics unit 14.
  • a plurality of semiconductor light sources 26 for emitting light are arranged grouped in the manner of a matrix.
  • electrical components of a control device are arranged on the printed circuit board 22, by means of which the individual semiconductor light sources can be controlled for light output.
  • the primary optics unit 14 has a primary optics element 32 which has a primary optics exit surface 36.
  • the primary optics element 32 also has a plurality of light entry surfaces (in Fig. 1 not shown), through which light can be coupled into the primary optics element 32.
  • the coupled light is in bundled or collimated by the primary optics element 32 and exits through the primary optics exit surface 36 and forms an intermediate light distribution there.
