  • the invention relates to a luminaire according to the preamble of claim 1.
  • a lamp meets e.g. in a motor vehicle depending on the design of various tasks or functions, such as in a design as a headlight a lightens the road function, or in a configuration as a signal light a signal function, such as to the direction indicator or display a braking action, or ensuring visibility of the motor vehicle by day and / or night.
  • lights are on the vehicle's bow, on the vehicle flanks and / or on the side mirrors and rear lights arranged flashing lights, for example, ambient lighting, marker lights, brake lights, fog lamps, reversing lights, and typically high set third brake lights, so-called Central, High-Mounted Braking lights, daytime running lights, headlamps and fog lights used as turning or cornering lights, as well as combinations thereof.
  • a luminaire for example for a motor vehicle, essentially consists of a housing, a reflector arranged therein, a light source typically arranged in front of the reflector, and a transparent cover protecting the reflector and the luminaire against the effects of weathering, also referred to as a light disc, which together with the housing enclosing a reflector and the light receiving space.
  • the housing or the space can be subdivided into a plurality of chambers, each with its own light sources, reflectors and optionally light disks, each of which chamber can fulfill another of the functions described above.
  • illuminants come e.g. in motor vehicles, for example, incandescent lamps, gas discharge lamps and increasingly also individually or in groups arranged light-emitting diodes (LEDs) are used.
  • LEDs light-emitting diodes
  • the lamp consists of a housing, as well as a lamp arranged in front of a reflector, which is arranged behind a lens.
  • the luminaire has optics disks laminating the switched-on illuminant at least in the area in front of the illuminant and / or a reflector opening of the reflector.
  • the switched-on illuminant is no longer recognizable from the outside as a bright spot of light.
  • a punctiform illumination image is present in the region of the reflector opening.
  • the lamp consists of a housing, as well as a lamp arranged in front of a reflector, which is arranged behind a lens. So that the luminaire has a desired color impression under virtually every viewing angle, which is as homogeneous as possible, and thus the luminaire is inexpensive to produce, an optical disc having a coloring is arranged directly on the housing at least in sections behind the luminous pane.
  • the lamp consists of a housing, as well as arranged in front of a reflector, designed as a light bulb, which is arranged behind a lens. So that the lamp in a simple, inexpensive way without affecting their lighting function has a modern, flawless appearance, is between the light panel and the bulb at least one optical disc with Lens elements arranged in the beam path of the light bulb. This ensures that the light gives the impression as if a variety of LEDs are used.
  • the lamp consists of a housing, as well as a plurality arranged in front of a reflector, designed as incandescent bulbs, which are arranged behind a common or a divided into different areas lens. So that the corresponding areas of the lens are not too different in color from neighboring areas, at least the areas of the lens which form a tail light or a boundary light are provided with triples reflecting extraneous light and are acted upon by the light reflected by a plurality of reflectors , Pre set of an optical disk, which is occupied by line-shaped, adjacent cylindrical lenses. This ensures that the entire directed by the reflectors light of several incandescent lamps radiates through these lens sections in the range of their light passages.
  • optical disks are used to obtain a homogeneous viewing image of a luminaire.
  • the invention has for its object to develop a luminaire with a spatial effect of the luminous surface.
  • optical disk has a spatial effect, e.g. generated in a tail light.
  • the arrangement of spherical elements between the reflector and the lens creates a three-dimensional appearance both in the illuminated, as well as in the unlit condition.
  • each individual ball element or ball produces a bright point of light. This point of light moves with the change of viewing direction and is still visible compared to conventional roll or cushion optics even if the luminaire is viewed laterally at a shallow angle.
  • the ball elements can be integrated into the optical disk in various ways.
  • the optical disk preferably comprises a plate, which connects the ball elements together.
  • the ball elements may be arranged on the plate interconnecting the ball elements, or the centers of the ball elements may lie in the plane formed by the plate.
  • the optical disk may also comprise a grid whose nodes are designed as ball elements.
  • the grid is flat, wherein adjacent, designed as ball elements node in the plane formed by the grid are interconnected by webs.
  • the webs extend at right angles to each other, or that the webs form a hexagonal honeycomb structure in a viewing direction perpendicular to the plane formed by the grid.
  • the optical disc may comprise a space grid whose nodes are designed as ball elements.
  • adjacent nodes configured as ball elements can be connected to one another by webs.
  • the webs may extend at right angles to each other, so that the space grid has a cubic spatial structure, or they may intersect each other so that the space grid has a hexagonal geometric space structure.
  • the luminous means preferably comprises at least one incandescent lamp and / or at least one LED and / or at least one gas discharge lamp.
  • the luminaire or the housing can be subdivided into a plurality of chambers, each with its own light sources, reflectors, optical disks, and, if appropriate, light disks, of which each chamber fulfills the same or different functions.
  • the in the Fig. 1 . 2 and 3 Illustrated, for example, designed as taillights for motor vehicles lights according to the invention each consist of a housing, not shown, a reflector 01, arranged in front of the reflector 01 bulbs 02, a lens 03 and one in the beam path between the bulb 02 and the reflector 01 and the lens 03 arranged optical disk 04.
