Definitions
- the invention relates to a vehicle lamp according to the features of the preamble of claim 1.
- a vehicle lamp with a housing and a lens that closes the housing is known.
- the vehicle lamp has at least one lamp chamber, which is arranged in the corner region of the motor vehicle in such a way that the light distribution generated occurs both to the vehicle's longitudinal axis and to the vehicle side.
- a light source and a Fresnel lens collecting the light from the light source are arranged in the luminaire chamber, which is arranged adjacent to the light disk in at least a partial area of the lens and extends essentially over the entire luminaire chamber.
- the Fresnel lens has at least one curved partial surface.
- Fresnel lenses used either have very simple geometries that do not guarantee the desired light distribution, or the Fresnel lenses have very complex, complicated, difficult-to-construct geometries, the construction and manufacture of which are very cost-intensive.
- the invention has for its object to provide a vehicle lamp which, by means of a Fresnel lens as the light-collecting means, achieves the best possible light distribution and light illumination extending into the side area of the vehicle and at the same time is simple and inexpensive to construct and manufacture.
- the object is achieved by the features of claim 1.
- the fact that the center of the concentrically arranged P ⁇ smen ⁇ nge is arranged in a first curved partial surface results in the advantage of the best possible use of the light rays emitted by the light source, which this center directly in the focal point of the lens stands opposite, for use for the essential light distribution area in the main light emitting device.
- the arrangement of a second partial area which extends into the side area of the lamp chamber results in the simple possibility of designing the light distribution for the side illumination in the best possible way.
- each partial surface can be constructed inexpensively as a simple geometric structure and tools can be created for simple and inexpensive manufacture, which are independent of one another Have surface areas to be processed with simple structuring.
- the concentric prism rings continue in alignment beyond the dividing line in the respective other partial area, thereby avoiding that, despite the combination of individual areas with different geometries, the lens is illuminated inconsistently.
- the configuration of the first partial surface as a spherical surface proves to be particularly advantageous, since the associated tool can be designed as a symmetrical rotating part
- the second and third partial surfaces are formed as essentially straight surface elements. If the third partial surface is designed as a conical surface, the tool used for the production can also be produced in a simple form as a turned part If the second partial surface is chosen as a slightly curved surface of free geometry, the surface of the tool for producing the Fresnel disk can be produced in this section in a simple form as a milled part.
- the free end section of the third partial surface can be adapted as best as possible to the profile of the vehicle lamp in the side region and thus to the profile of the vehicle body. In today's vehicle bodies, this area often has a curvature in all directions.
- the subdivision of the first partial surface into spherical surfaces having different radii results in the advantage that the Fresnel lens in the region of the strongest curvature of the Fresnel lens can be adapted as best as possible to the desired light distribution and the course of the lens.
- a particularly uniform illumination results if the concentric prism rings continue in alignment in all partial areas.
- FIG. 2 shows a horizontal section through a Fresnel lens according to FIG. 1,
- FIG. 3 shows a front view of a Fresnel lens according to FIG. 2
- Figure 1 shows a vehicle lamp for installation in the corner area of a motor vehicle.
- This vehicle lamp can, as in the embodiment shown here, be a rear lamp, or as a z.
- the vehicle lamp has a housing (G) which is closed by a lens (L). At least one lamp chamber (K) is arranged in the corner area of the vehicle in the housing (G).
- the lamp chamber (K) receives a light source (Q), which is inserted into the housing (G), for example via a socket (S).
- the lamp chamber (K) shown here has a Fresnel lens (F) as a light-collecting means, which extends essentially over the entire lamp chamber (K) and is arranged in at least one partial area adjacent to the lens (L).
- the Fresnel lens (F) is at the embodiment shown here divided into three partial surfaces (T1, T2, T 3) in order to enable the best possible illumination of the lens (L) in all surface areas while being as easy to manufacture as possible.
- the central partial surface (T1) is designed as a curved spherical surface and has the center of the concentrically arranged prism rings (P), not shown here, which continue in alignment in all partial surfaces (T1, T2, T 3) of the Fresenl lens (F).
- the light source (Q) with its light-emitting incandescent filament is arranged in the focal point of the Fresnel lens (F).
- the partial area (T2) adjoining the first partial area (T1) in the lateral area of the vehicle lamp extends in the area of the vertical dividing line (TL 1, 2) continuously into the geometric shape of the first partial surface (T1) via Furthermore, the second partial surface (T2) in the region of its free end is optimally adapted to the surface profile of the housing wall of the housing (G) and / or the surface profile of the lens (L) in this area .
- the second partial surface (T2) is used as a prism ring (P) or scattering elements supporting surface formed free geometry
- the generating tool can be designed as a milling part, for example
- the second partial surface can also be designed essentially in a straight line and the generating tool can be designed as a turned part.
- the first partial surface (T1) can extend as far as the housing (G) towards the center of the vehicle. In the exemplary embodiment shown here, however, the first partial surface (T1) merges continuously into a third partial surface (T3) in the region of the dividing line (TL 1, 3).
- the third partial surface (T3) of the Fresnel lens (F) can be designed as a substantially rectilinear surface or, as in the exemplary embodiment shown here, have a conical surface, so that the best possible adaptation and the best possible transition of the first partial surface (T1) in Area of the dividing line (TL1, 3) in the third partial area (T3) is guaranteed, since both areas in the area of the dividing line (TL 1, 3) have the same radius.
- FIG. 2 illustrates the structure of the Fresnel lens (F) shown here by way of example, with three partial areas (T1, T2, T 3) which continuously merge into one another at the dividing lines (TL1, 2 and TL 1, 3).
- the center of the concentrically arranged primer rings (P) and the associated focal point (B) of the Fresnel lens (F) can also be seen from FIG. Figure 2 also illustrates that the Fresnel lens (F) spans an angle of approximately 90 °. In other versions, the angle spanned by the Fresnel lens (F) in the horizontal section can be between 80 ° and 120 °. Furthermore, it can be seen from FIG.
- the prism rings (P) which can be designed as total reflection prisms and / or refractive prisms, have different designs in different areas of the Fresnel lens (F), which are adapted to the light distribution function to be achieved in each case.
- the ring prisms (P) around the center up to the free end section of the third partial surface (T3) are essentially designed as total reflection p ⁇ ms that block the light from here Deflect light source, not shown, in the main light emission direction.
- the prism rings (P) emit the light from the light source, not shown, in an emission direction between 0 ° and 45 °.
- the primer rings (P) on the second partial surface (T2) serve only for side illumination.
- Figure 3 shows the Fresnel disk (F) in a front view.
- the prism rings (P) arranged concentrically around the center (Z) and their continuous continuation beyond the individual partial areas can be seen.
- refractive prisms can also be used instead of total reflection prisms in the area indicated by the broken line, which extends around the center.
- the Fresnel lens (F) is preferably made in one piece from plastic.
