Definitions

  • the invention relates to a motor vehicle lamp according to the features of the preamble of claim 1.
  • a rear fog lamp for motor vehicles which has a reflector for focusing the light emerging from a light source, an optical disc being connected downstream in the beam path.
  • the optical disk has optically effective elements which are arranged adjacent to one another in rows.
  • a predetermined number of optically active elements is designed as lenses that scatter the incident light.
  • the other optically active elements are designed as prisms which have sawtooth-shaped cross sections in both a horizontal and a vertical plane in order to produce a uniform light distribution.
  • the prisms ensure that the uneven light distribution generated by the honeycomb-shaped, rectangular lenses, which has very high light intensities in a central region and light intensities that decrease sharply towards the edge, is compensated for, so that a maximum permitted light intensity in the central region is not is exceeded.
  • honeycomb-like, rectangular lenses which can be convex or concave, can only illuminate a given base area very unevenly and with emphasis on the center, so that this light distribution generated by the lenses determines the deflection angle for the vertically and horizontally acting prisms .
  • the outer optical disk In the motor vehicle lamp used here, which is designed as a rear fog lamp, the outer optical disk has a red color which corresponds to the color of the light emitted. If the outer lens is to be of a different color than that of the light emitted, the use of an additional color filter is required. With the light distribution that can be generated here, there is the disadvantage that, due to the reduction in light intensity by using the color filter to about half the previously achievable light intensity, the prescribed and / or required light intensities cannot be met or achieved in a predetermined light distribution range without that the optical disk is enlarged or the nominal power of the light source is increased.
  • the lamp known from DE-A-31 15 024 has the same combination of features as the lamp known from DE-A-17 55 770. This has the same disadvantages listed above.
  • a motor vehicle lamp which has a light source and has an optical disc connected in the beam path.
  • the light collection and light distribution takes place here exclusively through the optically acting elements of the optics disc.
  • the optically active elements are arranged here in rows adjacent to each other. All optically active elements are designed here as prisms, which act vertically and / or horizontally, so that the light emitted by the light source is directed by each prism in a predetermined direction. Any desired light distribution can be generated by such a configuration of the optical disk.
  • the disadvantage here is that the construction of such a lens is very complex and costly and that the tools for producing such a lens are expensive and subject to high wear during production. It proves to be particularly disadvantageous that if a reflector is not used to concentrate the light from the light source, only low light intensities can be achieved for a given light distribution, so that, for. B. the use of such a motor vehicle lamp as a rear fog lamp is not possible. This applies in particular if the light emitted by the motor vehicle lamp is to have a different color than the color of the outer optical pane, since in such a case an additional color filter is required which reduces the achievable light intensity by about half.
  • a motor vehicle lamp in which the color of the light emitted differs from the color of the outer cover plate.
  • This motor vehicle lamp has a light source and an optical disc, which is colorless.
  • a color filter is arranged between the light source and the optical disk.
  • the color filter is designed here, for example, like a dome or dome, so that it partially surrounds the light source.
  • the optical disk has prisms on the outer surface, which are used to collect the light emerging from the light source.
  • a colorless or color-neutral cover lens that carries a scattering optic creates the external appearance of the motor vehicle lamp.
  • the color filter has a collecting optic that is matched to the collecting optics of the optical disk.
  • No. 3,514,589 shows a lamp in which the color of the emitted light also differs from the color of the outer cover plate.
  • the use of a grating injected into a clear optical disk for coloring the optical disk not only results in the disadvantage of cost-intensive production, but the luminous flux which can be achieved is reduced. This is particularly the case if the light rays reflected back from the grating repeatedly shine through the filter arranged between the optical disk and the light source.
  • the invention has for its object to provide a motor vehicle lamp, the use of the smallest possible, the light distribution determining the outer optic disc, which is colored in a color that differs from the color of the emitted light, and when using a light source a normal nominal power ensures that a predetermined light distribution, in which the light is widely scattered horizontally and vertically only slightly and has a gain in a medium range, is achieved with the highest possible luminous intensity specified within limits.
  • a reflector and / or a lens is provided for bundling the light emerging from a light source, because the light from the light source is thus used as well as possible, thereby making it possible for the light source to have a customary nominal power.
  • the optical disc which is connected downstream in the beam path, has optically effective elements which are arranged adjacent to one another in rows, there is the advantage of a simple and inexpensive construction and manufacturability of the optical disc determining the light distribution.
  • a color filter is arranged in the beam path between the reflector and / or the lens for bundling the light and the optical disk and / or the beam path between the light source and the reflector or the lens for bundling the light, because it is very different Shapes and arrangements of the color filter are possible and in particular the position of the color filter relative to the optical disk can be freely selected, since the light distribution is determined by the optical disk.
  • This also has the advantage that the motor vehicle lamp is simple and inexpensive to manufacture.
  • each lens is designed as a concave or convex scattering lens with two scattering radii, which scatters the incident light onto a base surface arranged at a predetermined distance from the motor vehicle lamp, the advantage results that Base area is illuminated as evenly as possible in all areas, because each of the lenses illuminates the base area evenly due to the design as a diffusing lens with two diffusing radii.
  • the vertical spreading radius is larger than the horizontal spreading radius of the spreading lenses, because thus is achieved that the incident light is scattered more in the horizontal direction than in the vertical direction, whereby a rectangular base is illuminated as evenly as possible.
  • the remaining number of elements is designed as prisms, each prism being designed as a horizontally and / or vertically acting prism, which directs the incident light onto a given partial area of the base area, because that the partial areas of the base area which are illuminated by the prisms have a higher light intensity than the partial areas of the base area which are not illuminated by the prisms, as a result of which a predetermined light distribution with a light intensity which is predetermined within limits, i. H. a minimum light intensity and a maximum light intensity is also achieved if a color filter is connected upstream of the optical disc in the beam path, which reduces the light intensity by about half. If the motor vehicle lamp z. B.
  • a rear fog lamp which requires a high light intensity in a cruciform area of the base, which is more pronounced in the horizontal direction than in the vertical direction, can be achieved by illuminating this cruciform area through the prisms, the desired light distribution with the predetermined light intensity will.
  • the optical disk is subdivided into a predetermined number of basic elements, that each basic element has the same predetermined sequence and number of prisms and lenses, and that each basic element generates an identical predetermined light distribution because the predetermined light distribution with the minimum light intensity and maximum permissible luminous intensity can be adhered to as precisely as possible, since the different luminous intensities and luminous fluxes can be achieved by the predefined configuration of the subject matter of the invention, in which each basic element generates the same predefined light distribution be balanced and averaged at different locations on the optical disk, which would not be the case if optically active elements which illuminate the same partial area in the base area were combined into groups at predetermined locations on the optical disk.
  • each basic element has an equal number of lenses and prisms results in the advantage that, on the one hand, uniform and strong illumination of the base area is achieved and, on the other hand, there are sufficient prisms to illuminate large partial areas of the base area with a higher light intensity.
  • every second optically active element is a lens and the lenses and the prisms form a checkerboard pattern, because it is thus achieved that only a small number of prisms or no prisms with their side faces adjoin each other directly, thereby avoiding that due to the different angles that the prisms have, many steep interfaces arise, which would lead to the fact that the tools for producing the optical disk are complex in construction and manufacture and cost-intensive and cause high tool wear would, since the interfaces between the prisms must be very clean, so as not to limit the optical effectiveness of the prisms.
  • the uniformity of the illumination of the partial areas is increased and, on the other hand, some of the partial areas have an increased light intensity compared to other partial areas, as a result of which predetermined areas of the base area can be particularly emphasized in the light distribution.
  • the color of the lens is gray or the vehicle color is adapted or the color of the neighboring lights corresponds, because z. B. can be achieved that a rear lamp of a motor vehicle, which consists of several individual lights, provides a uniform appearance, or that the appearance of the motor vehicle lamp is adapted to the appearance in the color of the vehicle, with the overall result that the formation of Phantom light is suppressed.
