Definitions

  • the invention relates to a lens of a vehicle light having a plurality of light functions, with a first area, which represents the flashing light function, which has a yellow color, with a second area, which is arranged adjacent to the flashing light function, which represents the reversing light function, and which is crystal-clear, the yellow color of the first Area continues in the form of strips in the second crystal-clear area, so that crystal-clear strips alternate with yellow strips in the second area and the yellow strips consist of the same transparent yellow material as the first area of the lens.
  • a vehicle lamp which is sold under the order number 2 NR 006 682 by the company Hella KG Hueck & Co in Lippstadt, DE, several Has light functions.
  • the lens has a first area that represents the flashing light function and has a yellow color. Adjacent to the first area, the lens has a second area, which contains the reversing light function and is made crystal clear. The yellow color of the first area continues in stripes in the second clear area, so that crystal-clear stripes alternate with yellow stripes in the second area.
  • the strip-shaped area is bordered by a yellow-colored area which is ineffective in terms of lighting technology.
  • the yellow stripes are produced in that Direction of light seen from the back of the lens, opaque yellow stripes can be applied. Due to the opacity, the yellow stripes in the area of the reversing light function not only have a different color than the transparent yellow-colored material of the neighboring flashing light function, but also appear matt due to the lack of transparency and thus prevent a uniform appearance of the vehicle lamp.
  • the lens is divided into individual lenses; In addition, the vehicle lamp is constructed in two parts, the first part being arranged in the corner region of the vehicle and the second part being arranged in the movable trunk lid.
  • Lenses for producing the reversing light function are, for example, from French Offenlegungsschriften with publication numbers 25 97 191 A1 and 26 07 081 A1, such as also known from the Italian utility model with the publication number 199 466.
  • either optical elements are used to prevent the colored stripes from radiating through and / or the colored stripes are covered at the rear by opaque means. All of these measures are cost-intensive and do not lead to the desired transparency of the colored strips.
  • the invention has for its object to provide a lens for a reversing light function, which is simple and inexpensive to produce, alternate with the clear and yellow stripes, the yellow stripes have a high transparency and color purity and the color location of the reversing light function is not inadmissibly shifted to the color yellow becomes.
  • the object is achieved in that, seen in the direction of light, the outer surface of the lens is made crystal clear in the entire second area representing the reversing light function, that the yellow stripes are injected from behind into the crystal-clear second area, that the yellow stripes are seen in the direction of light have on their front a light-deflecting prism optics and that the light rays passing through the yellow stripes intersect the light rays passing through the crystal-clear stripes.
  • the outer surface of the lens is made crystal clear in the entire second area, which represents the reversing light function, and that the yellow stripes are injected from behind into the clear second area, because it is thus simple and inexpensive to manufacture Lens is guaranteed.
  • the yellow stripes seen in the direction of light have a light-deflecting prism optics on their front and that the light rays passing through the yellow stripes, which cut through the crystal clear stripes, because this creates an easy-to-manufacture and therefore inexpensive lens design, through which the reversing light function meets the legal requirements perfectly, but the lens for a uniform appearance of the vehicle lamp has yellow, light-penetrated light , has transparent stripes, the light passing through the yellow stripes being deflected into angular areas that lie outside the areas required and to be measured for the light distribution of the reversing light function.
  • the essential warning function of the reversing light in addition to the desired illumination function, is ensured without the risk of confusion with the information and warning function of the adjacent flashing light.
  • the prism optics are optically ineffective retroreflector optics, whereby an inventive deflection of the light rays passing through the yellow stripes is achieved in a simple and inexpensive manner, for example using retroreflector triplets.
  • the ineffective reflector optics continues in the first region in the form of a strip, which enhances the uniform appearance of the lens of the vehicle lamp. This is particularly true if the reflector optics are found in other light functions of the vehicle lamp.
  • the fact that the light entry surfaces of the prism optics are matted has the advantage that the light deflected by the prism optics is additionally scattered, thereby reducing the appearance of a yellow effect outside the light distribution for the reversing light function.
  • the light entry surfaces of the crystal-clear strips are the light horizontally and / or vertically scattering lenses, whereby besides a desired structuring in the area of the crystal-clear strips, an optimal light distribution of the reversing light function is achieved.
  • the fact that the light rays incident on the lens have a pre-direction required for the generation of the reversing light function results in the advantage that the lens can be constructed as simply as possible and, if structuring in the crystal-clear strips is undesirable, on optical means in the crystal-clear strips can be dispensed with.
  • the pre-alignment is carried out by a reflector or an additional light disk.
  • the reflector can be designed as a step reflector or an open space reflector.
  • the additional light disk can be designed, for example, as a specially designed Fresnel lens.
  • the yellow stripes have a smaller width than the crystal-clear stripes, there is the advantage of a high luminous efficacy for the reversing light function.
  • the other light functions arranged adjacent yellow stripes have a yellow border, whereby the stripe-shaped reversing light function is embedded in a yellow-colored area and thus the uniform appearance of the lens of the vehicle lamp is increased.
  • the single figure shows a section of a lens according to the invention in section with a drawn beam path.
  • the lens shown in the figure is used in a vehicle lamp that has several functions, but at least the flashing light and reversing light functions. These two light functions are arranged adjacent to one another, the arrangement being able to take place both one above the other and next to one another.
  • the individual light functions can have individual light panes, but several or all light functions can also be covered by a single light pane which is made in one piece.
  • the vehicle lamp can be made in two parts.
  • a section through a lens which has a first region (B1), which represents a flashing light function and consists of a material that has a yellow color.
  • Adjacent to the first area (B1) is a second area (B2) representing the reversing light function, the outer surface (A) of which consists of a crystal-clear material over the entire area of the reversing light function.
  • This crystal-clear outer surface (A) is seen in the direction of light (L) and is provided with yellow stripes (GB) from behind, which continue from the adjacent first area (B1) of the flashing light function into area (B2) of the reversing light function.
  • the crystal-clear outer surface (A) is back-injected with yellow stripes (GB), that is to say the yellow stripes (GB) are injected into the crystal-clear second region (B2) from behind.
  • the yellow stripes (GB) consist of the same transparent yellow material as the first area (B1) of the lens, which represents the flashing light function. Between the yellow stripes (GB) there are crystal clear stripes (GK) which alternate with the yellow stripes (GB).
  • the yellow stripes (GB) In order to achieve a light deflection of the light rays (LS) shining through the yellow stripes (GB), which lies outside the light distribution that is prescribed for the reversing light function, the yellow stripes (GB), viewed in the light direction (L), have on their front side light-deflecting prism optics (P).
  • the light deflection of the prism optics (P) is designed in such a way that the light rays that radiate through the yellow stripes (GB) are deflected in such a way that they intersect the light rays (LS) passing through the crystal-clear stripes (GS), as a result of which they are outside the light distribution for the reversing light lie and a shift of the color location of the reversing light function to the color yellow in the range of the prescribed light distribution for the reversing light function is avoided.
  • the prism optics (P) can consist of a known, ineffective retroreflector optics, for example with retroreflector triples, whereby a fine structuring of the yellow stripes (GB) is achieved and a high transparency of the yellow stripes (GB) is ensured.
  • a strip-shaped continuation of the reflector optics in the first area (B1) increases the uniformity of the appearance of the lens of the vehicle lamp.
  • the light entry surfaces of the prism optics (P) are matted, as a result of which an additional, arbitrary scatter is achieved.
  • the light entry surfaces of the prism optics (P) can also be overlaid by lenses.
  • the yellow stripes (GB) can Different prism optics (P) are used, whereby both roof prisms and individual prisms with different pitches can be used.
  • the light entry surfaces of the crystal-clear strips (GK) are designed as the light rays (LS) horizontally and / or vertically scattering lenses (SL), the word "scattering” referring to the desired light distribution to be achieved.
  • the use of prism optics is necessary, or else it is necessary to pre-align the light rays (LS) that strike the lens.
  • the ratio of the widths of the yellow stripes (GB) to the crystal clear stripes (GK) can be changed depending on the desired visual appearance of the lens. It is advantageous if the crystal-clear stripes (GK) are wider than the yellow stripes (GB), which increases the light output for a given light exit area for the reversing light function. In other versions of the lens, the yellow stripes (GB) and the crystal-clear stripes (GK) can also be the same width. The yellow stripes (GB) can also be wider than the crystal-clear stripes (GK).
  • the yellow stripes which are arranged directly adjacent to other light functions, have a yellow border (R).
  • the reversing light function thus appears as a stripe-shaped window in a uniform yellow color Section.
  • chambers can be provided inside the vehicle lamp.
