Definitions
- the present invention relates to a headlight for a motor vehicle according to the preamble of claim 1.
- Such a headlight must, among other things, meet the lighting requirements of the respective approval area, such as ECE or CCC or SAE.
- the photometry to be fulfilled also shows what are known as OS values (overhead sign values). These are measuring points that lie above the light-dark boundary of the light distribution.
- a headlight of the type mentioned is known from DE 102016 109 132 A1.
- the headlight described therein comprises a plurality of first light sources designed as light-emitting diodes for a high beam and for a low beam.
- the headlight also includes primary optics consisting of two light guides, into which the light emitted by the light-emitting diodes is coupled.
- the headlight also includes secondary optics designed as a projection lens, which can project the light emanating from the primary optics into the exterior of the motor vehicle.
- the light distribution generated by the headlight has a horizontal light-dark boundary and light components arranged above this light-dark boundary to implement an OS function (overhead sign function).
- a prismatic step is formed on a first of the light guides of the primary optics, through which light exiting from the second of the light guides can enter the first light guide. This portion of the light that has entered the first light guide from the second light guide is deflected upwards by the secondary optics, so that it reaches an area above the light-dark boundary of the low beam.
- the disadvantage here is that additional geometries on the primary optics or on the projection lens mean increased production costs and lead to ner increased susceptibility to errors.
- the increased susceptibility to errors can be caused, for example, with regard to the functionality by deviations in shape or with regard to the optical quality by air inclusions or streaks or flow lines or the like.
- headlight is known from DE 102009020593 A1.
- secondary optics designed as a plano-convex projection lens are provided, which have more than one hundred discretely distributed projections on their convex surface, which are used to implement an OS function.
- geometries added to the projection lens usually have the major disadvantage that they are visible when looking at the headlight and thus have a negative effect on the external appearance of the headlight.
- headlight is known from EP 2730836 A1.
- a metallic screen is provided between a primary lens and a secondary lens.
- the panel has reflective surfaces that are used to implement an OS function.
- the panel is an additional component that results in increased production, assembly and adjustment costs.
- the problem on which the present invention is based is the creation of a headlight of the type mentioned at the outset, which can be produced more cost-effectively and/or enables OS values to be generated using simple means.
- the headlight is set up so that a portion of the light emanating from the primary optics is reflected back from the secondary optics to the primary optics, that this reflected back portion of the light from of the primary optics is reflected in the direction of the secondary optics and, after passing through the secondary optics, is deflected into an area above the cut-off line to implement the OS function.
- the manufacturing effort can be reduced, for example, by dispensing with additional mold inserts for introducing the additional geometries into the primary optics or the secondary optics. Furthermore, errors caused by the additional geometries, such as air inclusions or streaks, can be avoided. Another component such as a reflecting panel or the like is also not required. As a result, the OS values can be generated without changing a specified design of the headlight.
- Another advantage lies in the use of the light reflected back by the secondary optics to generate the OS values. If not used consciously, this reflected light would propagate in the headlight as disturbing scattered light and possibly lead to undesirable effects such as light spots in the light distribution or glare or the like.
- the primary optics can have a surface facing the secondary optics, which is set up to reflect the portion of the light reflected back by the secondary optics in the direction of the secondary optics.
- the surface of the primary optics facing the secondary optics can be aligned in such a way that the normal to the surface when the headlight is installed in the motor vehicle encloses an angle equal to 0° or not equal to 0° with the horizontal.
- the surface of the primary optics facing the secondary optics can be aligned in such a way that the propagation direction of the portion of the light reflected by the surface in the direction of the secondary optics is inclined upwards and/or downwards relative to the horizontal when the headlight is installed in the motor vehicle. For example, by tilting it downwards Part of the light are deflected upwards in a projection by the secondary optics, so that it reaches an area above the cut-off line.
- the surface of the primary optics facing the secondary optics is provided with a reflective coating.
- the degree of reflection of the surface of the primary optics facing the secondary optics can be increased, so that a larger part of the light reflected back can be used to generate the OS values.
- the surface of the primary optics facing the secondary optics can be concavely or convexly curved.
- the back-reflected light can be shaped and reflected again in the direction of the secondary optics in such a way that the shaped and reflected light can be used to generate the desired OS values.
- the surface of the primary optics facing the secondary optics is part of the at least one light exit surface of the primary optics or corresponds to the at least one light exit surface.
- the surface of the primary optics facing the secondary optics is not part of the at least one light exit surface of the primary optics and/or does not correspond to the at least one light exit surface.
- the surface of the primary optics facing the secondary optics can be formed, for example, on a base, in particular a base plate of the primary optics.
- the secondary optics prefferably have a light entry surface for the light emanating from the at least one light exit surface of the primary optics and a light exit surface for the light entering through the light entry surface.
- the light entry surface of the secondary optics can be set up to to reflect the portion of the light emanating from the primary optics back to the primary optics.
- the secondary optics can thus contribute to the realization of the OS function without geometric modification.
- the at least one light source can be in the form of a light-emitting diode or laser diode, in particular with a plurality of light-emitting diodes and/or laser diodes serving as light sources being provided.
- the primary optics can have a plurality of light entry surfaces, with each of the light entry surfaces being assigned at least one of the light sources in such a way that the light emanating from the light source enters the assigned light entry surface.

- the headlight shown comprises a plurality of light sources 1 which emit light 2 when the headlight is in operation.

- the primary optics 3 also has a base plate 7 on which the collimation optics 4 are arranged.
- the headlight also includes a secondary optics 8, which is designed as a single lens in the illustrated embodiment.
- the lens can be designed as a plano-convex lens, for example. It is definitely possible to provide more complicated secondary optics, for example one consisting of several components.
