Definitions

  • the invention relates to a light module for a headlamp of a motor vehicle, comprising a light source that emits light, and at least one optical element that converts a portion of the light into a bright area of a low beam light distribution generated by the headlamp in its apron a light-dark boundary is limited, which is generated as an image of the current of the light generated by the light source spatially limiting edge.
  • a light module is here assumed to be known per se.
  • So-called projection light modules are known from the prior art, in which one or more primary optics depict one or more light sources on a focal surface. This results in the focal surface of a first light distribution, which is imaged by a secondary optics in a second, lying in the run-up of the motor vehicle light distribution.
  • the cut-off line is created by the edge of an aperture. If the edge lies in the focal surface of the secondary optics, it is imaged by this as a sharp cut-off in the second light distribution. Because the secondary optics images the first light distribution generated in the focal plane upside down and laterally reversed, light that passes through the focal surface above an optical axis of the secondary optics is imaged below the optical axis.
  • the second light distribution is a rule-compliant low beam light distribution.
  • the diaphragm is designed as a horizontal surface in the light module, which has a reflective surface.
  • Light which would normally be shadowed by a vertically arranged aperture hits the reflective surface and is reflected upwards by it.
  • the reflected light passes through the focal plane above an optical axis and is therefore imaged by the secondary optics into the brighter area below the cut-off line.
  • the light reflected from the aperture surface increases the efficiency of the light module.
  • This area also called overhead area, serves, for example, to illuminate traffic signs arranged above the roadway.
  • a conformal overhead light distribution must be such that it has sufficient light intensity in a limited angular range above the cut-off line, while avoiding dazzling oncoming traffic.
  • projection light modules are designed for vertically very narrow light distributions or, for reasons of efficiency, have a first light distribution, which is formed mainly by beams which originate directly from the light source and have few or no reflected components.
  • the object of the invention is to specify a light module of the type mentioned above, with which a rule-conforming overhead light distribution can be represented.
  • the invention differs from the prior art known at the outset as known per se in that a further part of the light is deflected at a first reflection surface into an overhead beam path and lies as overhead light in an area beyond the cut-off line less brightly illuminated area of the second light distribution is converted, in which a rule-compliant dipped beam local has to achieve predetermined brightness values, wherein in the overhead beam path at least a second deflection of the overhead light takes place on a second reflection surface.
  • the first of the two deflections separates the overhead light from the remaining light that produces the low beam distribution.
  • the second deflection allows an individual influencing of the separated light with the aim of generating a rule-compliant overhead lighting.
  • the embodiments described below relate to projection light systems, in which a primary optics initially generates a light module-internal first light distribution, which is projected by an imaging optical system in the apron of the headlight.
  • the invention can also be easily transferred to direct imaging systems in which e.g. a light exit surface of a semiconductor light source is projected by projection.
  • a preferred embodiment is characterized in that the light module has at least a primary optic, an imaging optic and a diaphragm, the primary optics collecting light emitted by the light source and producing therefrom a first light distribution which lies in a focal plane of the imaging optic, the imaging optics thereto is configured to image the first light distribution in a lying in a run of the light module second light distribution, and wherein the aperture has the optically effective edge and wherein the edge lies in the focal surface and limits the first light distribution and thus as a light-dark boundary in the second light distribution is imaged, and wherein the aperture has a recess which through the first Reflection surface and the second reflection surface is limited, wherein designed as a first reflection surface boundary surface of the recess of the light source and the second reflection surface, so that it deflects light incident thereon from the light source to the second reflection surface and wherein the configured as a second reflection surface boundary surface of the recess the first reflection surface and the secondary optics faces and directs incident light from the first reflection surface forth on the
  • the above-mentioned disadvantages of failure to meet the requirements for the overhead illumination intensity in a diaphragm with a recess provided for generating the overhead lighting are avoided. This is achieved by the double deflection, which allows a targeted directional influence of the light used to generate the overhead light. It is also preferred that the diaphragm is a one-piece cohesively connected plastic injection-molded part, which is demoldable without undercut. This is a particularly cost effective alternative.
  • the panel has a sheet metal part forming the front panel edge, which is encapsulated in plastic or connected to a plastic part, wherein the opening is arranged in the plastic part.
  • the diaphragm is made of metal. This is also a thermally highly resilient design. In this case it is not necessarily it is necessary to mirror or coat the reflective surfaces, but it is sufficient to mold more or less polished tool surfaces. This saves the cost of additional operations such as coating or polishing the reflective surfaces.
  • the aperture has a recess formed by punching or cutting, wherein the recess results as a result of a continuous separation of the diaphragm material on three sides of the recess and over a fourth side of the recess downwardly deflecting the resulting tongue a surface of the bent tongue forms the second reflecting surface.
  • the invention can be implemented easily and inexpensively.
  • the first reflection surface and / or the second reflection surface in their vertical extension is in each case a flat surface.
  • This embodiment has the advantage that the shape (divergence) of the reflected beam is not changed. Instead, only the direction of the light and / or its distance to the optical axis is changed.
  • reflecting surfaces arranged perpendicularly to the optical axis ensure a parallel displacement of the reflected light.
  • the parallel shifted light occurs as a result of the parallel displacement and the greater distance from the optical axis to more curved areas of the imaging optics and experiences there correspondingly a greater deflection.
  • the light can be targeted to areas of the secondary optics, which cause a change in direction required for the desired overhead lighting.
  • a further advantageous embodiment provides that the first reflection surface and / or the second reflection surface is convexly curved in its vertical extension.
  • the convex curvature of the reflection surfaces causes a bundle of rays to expand vertically during the reflection. This results in a vertically wide first light distribution in the focal surface, which is imaged by the secondary optics in a vertically wide second light distribution.
  • the irradiated amount of light is distributed over a larger area, the illuminance of this area decreases.
  • the first reflection surface and / or the second reflection surface is concavely curved in its vertical extent.
  • the concave curvature of the reflection surfaces leads to a bundle of rays being vertically focused during the reflection. This results in a vertically narrow first light distribution in the focal surface, which is imaged by the secondary optics in a vertically narrow second light distribution. In this way, a narrower in the vertical direction angle range is illuminated than with flat reflecting surfaces.
  • the amount of light irradiated is distributed to a smaller area, the illuminance of this area increases.
  • first reflection surface and / or the second reflection surface are convexly curved in their horizontal extension.
  • the convex curvature of the Reflection surfaces cause a bundle of rays to expand horizontally during reflection. This results in a horizontally wide first light distribution in the focal surface, which is imaged by the secondary optics in a horizontally wide second light distribution.
  • the irradiated amount of light is distributed over a larger area, the illuminance of this area decreases.
  • the first reflection surface and / or the second reflection surface are concavely curved in their horizontal extent.
  • the concave curvature of the reflection surfaces causes a bundle of rays to be horizontally focused during the reflection. This results in a horizontally narrow first light distribution in the focal plane, which is imaged by the secondary optics in a horizontally narrow second light distribution. In this way, an angle range smaller in the horizontal direction is illuminated than with flat reflecting surfaces.
  • the amount of light irradiated is distributed to a smaller area, the illuminance of this area increases.
  • the invention permits in each case an adjustment of the intensity and the position of the overhead light distribution by a specific definition of the Geometry of the two reflection surfaces, because this geometry determines the direction and divergence (opening angle) of each reflected light beam.
  • the first reflection surface and / or the second reflection surface are tilted against the focal surface.
  • one or both reflection surfaces are inclined relative to the focal surface so that the light reflected twice at them passes through the focal surface at the same location as the light passing directly through the recess. Because the light reflected twice at the inclined reflection surfaces passes through the imaging optics at a location closer to the optical axis, imaging optics with a smaller vertical extent can be used, as long as the other beam paths allow. Smaller imaging optics, are cheaper to produce and lead to a reduction in the sizes of the light modules. In addition, they contribute to a reduction in fuel consumption due to their lower weight.
  • the two reflection surfaces can also be arranged independently of a recess in the diaphragm.
  • the imaging optics has a special zone, similar to a progressive or two-strength spectacles, by which the light reflected at the two reflection surfaces light is deflected into a rule-compliant overhead area.
  • An embodiment with reflection surfaces that are separate from the diaphragm can also be combined with a diaphragm that has no recess.
  • All of the above-mentioned variants of the arrangement and shape of the reflection surfaces can also be used to guide part of the light to generate the rule-conforming overhead light distribution past the imaging optics.

  • the light source 12 is a semiconductor light source or an array of semiconductor light sources.
  • Semiconductor light sources in particular light-emitting diodes, are generally half-space radiators and thus differ from incandescent lamps and gas-discharge lamps, which can be considered approximately as isotropically emitting light sources 12. For this reason, another light-collecting element 16 is used as the light source 12 for the semiconductor light source design.

  • the reflection surface is concavely curved, for example in its horizontal extension, the beam reflected on it is focused in the horizontal.
  • the bundle of rays reflected on them is focused or widened in the vertical direction.
  • Reflective surfaces 36, 38 curved around the vertical produce an expansion or focusing of the overhead light distribution in the horizontal.
  • the reflection surfaces 36 and or 38 are curved around the horizontal, the overhead light distribution is widened or focused in the vertical direction.
  • the Fig. 6 shows a schematic representation of the light source 12 arranged thereon with primary optics 16, and the diaphragm 18 with the recess 34, and the secondary optics 22.
  • the diaphragm edge 20 is also here in the light source side focal surface 40 of the imaging optics 22.
  • the second reflection surface 38 is arranged tilted relative to the first reflection surface 36.
  • the first reflective surface 36 is parallel to the focal surface 40, while the second reflective surface 38 is not parallel to the focal surface 40.
  • the lower end of the second reflection surface 38 in the figure is closer to the focal surface 40 than the upper end of the second reflection surface 38 closer to the horizontal mirror surface of the diaphragm.
  • the dual-reflected beam 44 passes with smaller distance to the optical axis 24 through the imaging optics 22 than the beam 47.
  • the vertical width of the second light distribution 26 with respect to Use of aperture 20 with recesses 34 without reflective surfaces 36 and 38 not changed. This shows that by tilting the reflective surfaces 36 and / or 38, it is possible to use imaging optics 22 of lesser vertical extent to obtain a second light distribution 26 having a width such as recesses 34 without first reflective surfaces 36 and second reflective surfaces 38 would come.
  • the tilt of the second reflection surface 38 is shown about a first axis which is perpendicular to the optical axis 24 and points in the plane of the drawing. It is also conceivable tilting of the reflection surface about a second axis, which is neither parallel nor antiparallel to the first axis and the optical axis.
  • FIGS. 3 to 6 show embodiments in which the first reflection surface 36 and the second reflection surface 38 are each inclined in pairs planar, concave, convex or relative to the focal surface 40.
  • the reflective surfaces 36 or 38 conceivable that serve to produce a rule-conforming overhead light distribution.
  • the overhead light 46 consists of a direct and a reflected portion.
  • this also means that the two partial light bundles must have similar opening angles and leave the opening in approximately the same direction. The fulfillment of these conditions is required so that the two light beams can overlap to a light distribution.
  • the two mirror surfaces are designed straight so that the reflected light beam fulfills the conditions for the superposition of the two bundles.
  • FIGS. 7 and 8 show experimentally determined second light distributions 26 for a diaphragm 18, which has a recess 34. It concerns the Fig. 7 a diaphragm 18, as known from the prior art, and the Fig. 8 relates to an embodiment with a diaphragm 18, which has a recess 34, a first reflection surface 36 and a second reflection surface 38, wherein the first reflection surface 36 and the second reflection surface 38 are arranged substantially parallel to the light source side focal surface 40 of the imaging optics 22.
  • Fig. 7 shows a light distribution, which has with a known light module with a mirror aperture with single recess
  • the Fig. 8 shows a shifted by double reflection and deformed light distribution, as was generated with an embodiment of a light module according to the invention, which only by the execution of the mirror aperture with the two additionally distinguishes reflective surfaces 36 and 38 from the known light module.
  • FIGS. 7 and 8 are on the abscissa each indicate the horizontal angle of the light distribution 26.
  • the ordinate axes represent the vertical angles.
  • the HV intersection lies in an extension of the optical axis 24 in front of the headlight.
  • Measurement points 50 lying above the horizon, at which the overhead light distribution must assume legally prescribed illumination intensities, are in the FIGS. 7 and 8 marked by crosses.
  • the cut-off point 28 is clearly visible, which according to the legal requirements must be about 1 ° below the horizontal (0 ° line in the diagram).
  • the closed curves are each Isolux lines, ie lines of the same illuminance, whereby the illuminance increases from line to line from outside to inside.
  • FIG. 7 It will be seen that the aperture 18 with the recess 34 without additional reflecting surfaces 36 and 38 is not sufficient to meet the legal requirements. This is reflected in the fact that in the upper measuring points 50 the legally required illuminance levels are not reached, or in that the total overhead light distribution 52 is too close to the cut-off line 28. Such overhead lighting serves its purpose of illuminating Road signs arranged above the road are not sufficient.
  • FIG. 8 shows an overhead light distribution 52 with sufficient illuminance levels in the legally prescribed measuring points 50th
