Definitions

  • the invention relates to a lamp for vehicles according to the preamble of Claim 1.
  • a lamp for vehicles that has a has light-scattering reflector with parallel projections.
  • One the reflector covering lens has a series of parallel elevations on the inside on, which are arranged perpendicular to the reflector projections.
  • the width of the contiguous surveys is much larger than that Distances of adjacent projections of the reflector, so that the lamp from provides a uniform and harmonious appearance on the outside.
  • DE 196 30 410 A1 relates to lights for vehicles, the shape the lamp is adapted to the aerodynamic shape of the vehicle body. In many cases, however, this requires an asymmetrical shape of the reflector, see above that a paraboloidal reflector cannot be used. It will proposed to provide the reflection surface as reflection levels that between adjacent and closed curves of paraboloids are arranged. To create a latticed appearance of the lamp the lens divided into lattice-shaped sections, each in one Fisheye lens is shaped.
  • Reflector must have a relatively complex structure in order Interaction with the lattice-shaped structure of the lens is an aesthetic one To create appearance.
  • the object of the present invention is therefore to provide a lamp of this type train that it can be adapted to the shape of a vehicle, wherein the reflector generates sufficient light intensity, and that in a simple way created an aesthetic appearance of the lamp from the outside becomes.
  • the invention has the features of Claim 1 on.
  • a reflector By combining a paraboloidal reflector section with a .Floor area reflector section, a reflector is easily formed, the paraboloid-shaped reflector section essential for generating the contributes the required light intensity and the open-space reflector section is shaped that the lamp in an arbitrarily shaped recess Vehicle body can be used. Further through training of parallel elevations on the open-space reflector section and / or the paraboloidal reflector section on the one hand and perpendicular to these standing parallel elevations on the lens on the other hand creates aesthetic effect of the lamp.
  • the elevations of the second reflector section and the lens as a convex Cylinder surfaces formed, which are easy to manufacture Reflector section can be applied.
  • the radius of the cylinder surfaces is determined in such a way that the cylindrical surfaces have a section with a cross section form an acute angle so that the entire cylinder surface for reflection of the the light source emitted light can contribute.
  • the surveys are the second Reflector section and the elevations of the lens to each adjacent elevations of the second reflector section or the lens spaced by the same amount so that the lamp is a matrix or has a grid-like appearance, so that a good aesthetic effect is achieved.
  • the reflector is an elongated one Reflector formed, the second reflector section in the longitudinal direction in is essentially flat and paraboloidal in the transverse direction. This allows an elongated luminaire with good light output in Longitudinal direction are created.
  • the lamp according to the invention also as part of a multi-chamber rear light be designed for motor vehicles, being a brake light and / or Direction indicator is used.
  • the lamp according to the invention is also as a tail lamp, especially a rear fog lamp or a rear tail lamp applicable.
  • a flashing light shown in FIGS. 1 and 2 has an elongated one Reflector (1), which is completed by a lens (2).
  • the Turn signal lamp has a front circumferential contact surface on which a corresponding edge of the lens (2) rests.
  • the contact area is oval-shaped and in a corresponding recess of the Bordered vehicle body, with long sides (5) of the reflector (1) in extend substantially in the horizontal direction.
  • a reflection area (6) which is a paraboloid-shaped first Reflector section (7) and a second reflector section (8).
  • a socket (9) is provided in which Incandescent lamp (10) is held.
  • the second reflector section (8) is an open area reflector section formed, being substantially flat in the horizontal direction and in is formed paraboloid in the vertical direction.
  • the second reflector section (8) forms in a horizontal direction to the optical axis of the incandescent lamp (10) an acute angle so that there is no shadow formation even in the outer area takes place, but the entire surface of the second reflector section (8) of the light bulb (10) is detected and illuminated.
  • the reflector surface of the second Reflector section (8) is formed by arranged side by side Elevations which are designed as convex cylindrical surfaces (11).
  • the Cylinder surfaces (11) each extend from the upper side (5) to opposite lower side (5).
  • the cylinder surfaces (11) are each symmetrical with respect to a longitudinal median plane (M) of the respective elevation educated.
  • the radii of the inner cylinder surfaces (11) are so large chosen that the reflection surface of the cylindrical surfaces (11) in cross section each form a sector with an acute angle.
  • the outer cylinder surfaces (11) each form a sector with an obtuse angle in cross section, so that in the outer region of the reflector section (8) less scatter is generated and thus a homogeneous light distribution is guaranteed.
  • the width of the contiguous Cylinder surface (11) is approximately 6 mm. The width of the cylinder surfaces (11) can alternatively be chosen larger or smaller.
  • the first reflector section (7) has parallel elevations (12), which are each extend as an arcuate cylindrical surface between the sides (5) and have such a distance from one another that the boundary lines of the Elevations (12) in the front view of the housing (1) the same distance have like the cylindrical surfaces (11) of the second reflector section (8).
  • the elevations (12) are preferably also cylindrical surfaces educated.
  • the reflector section (7) can also have a drop-shaped cross section. Important is that in cooperation with the shape of the reflector sections (7, 8) the drop shape is chosen so that no shadow formation from the Incandescent lamp (10) emitted light rays at the elevations.
  • the lens (2) has a series of parallel inward facing Elevations as cylindrical surfaces (13), the width and curvature of which correspond to the cylindrical surfaces (11) of the second reflector section (8).
  • the Cylinder surfaces (13) extend essentially perpendicular to the Cylinder surfaces (11) and the elevations (12) of the second reflector section or the first reflector section (7).
  • the individual grid elements have the same square shape.
  • the cylinder surfaces (11) or Elevations (12) extend in the horizontal direction, whereas the Cylinder surfaces (13) of the lens (2) run in the vertical direction.
  • the cylinder surfaces (11, 13) on the one hand and the elevations (12) on the other hand have such a different width that the lamp in Front view has a rectangular appearance.
  • the distance of the Cylinder surfaces (13) to adjacent cylinder surfaces (13) is, for example 8 mm, and the distance between the cylinder surfaces (11) to each other, for example 6 mm.
  • the reflector (1) Since the cylindrical surfaces (11, 12, 13) to produce the lattice-like structure can be arranged discontinuously to the adjacent cylinder surfaces (11, 12, 13) the reflector (1) has almost any shape. Alternatively, the Cylinder surfaces also extend concavely.
  • the reflector (1) is off made of a PC and ABS plastic material and has a reflective Coating on.
  • the lens (2) is made of a transparent Made of PMMA plastic material.
