Definitions

  • the invention relates to a light emitter, such as a headlamp, a signal emitter, a lighting fixture or the like, with an essentially flat, translucent emitter element, in the peripheral edges of which a plurality of light elements are embedded, the edges being provided with a reflective layer.
  • the front of the radiator element is designed as a radiation surface and the back is completely provided with a reflective layer.
  • the defect of an individual acts due to the large number of light-emitting elements, which are preferably designed as light-emitting diodes LED only insignificantly, so that no safety problems arise and an immediate replacement is not necessary.
  • a very large number of light-emitting diodes can be arranged on the peripheral edges, so that, in particular when using modern high-performance diodes, such a large amount of light can be generated that use as headlights. Taillight or the like is possible.
  • the front side is provided with a reflective layer in the area on the edge which has the lighting elements.
  • the light can only reach the central region of the emitter element in order to be emitted to the front from there.
  • the front side and / or the edges and / or the rear side of the emitter element advantageously have a shape that bundles the light.
  • the front is preferably convex, and / or the rear is conically shaped inwards, and / or the edges have an essentially concave cross section.
  • the front, the edges and / or the back of the emitter element are provided with elevations or depressions that focus the light.
  • the choice of means depends not least on whether the light should be emitted essentially in parallel or in a desired cone.
  • the individual measures can have an additive or additional effect.
  • the shape of the emitter element also specifies the directional characteristic of the light, which means that the reflective layer or the reflective coating on the back replaces a separate directional reflector and a separate radiation optics.
  • the reflective layer is evaporated, glued on or applied galvanically in a simple and inexpensive manner.
  • the reflective layer can also expediently be connected to a heat sink.
  • the emitter element can be designed as a plastic body in the form of a motor vehicle rear light, in which brake light, reversing light and / or turn signal functions are also included.
  • Different light-emitting diodes can be used to generate either red, yellow or white light, depending on which function is currently required.
  • the radiator element as a motor vehicle headlight, for. B. trained as parking lights, so of course only the white color or, for example, only the yellow color is required for French vehicles.
  • An expedient embodiment also includes training as a construction site warning light, the light-emitting diodes being operated in pulsed mode at increased output. In pulsed operation, the LEDs can be operated at up to ten times the current strength.
  • a headlamp consists essentially of a translucent radiating element 10, which is made as a round plate made of glass or transparent plastic material such as acrylic glass. The material can also contain fluorescent particles. While the rear 11 of the radiator element is flat, the front 12 is convex in the manner of a converging lens. In the peripheral edge 13 of the radiator element 10, twelve light-emitting diodes 14 are inserted at regular intervals into corresponding insertion openings. This number is of course arbitrary and depends on the desired amount of light to be achieved. In the case of a headlight, the arrangement can be considerably denser than, for example, in the case of a rear light of a motor vehicle.
  • the rear side 11, the edge 13 and a strip-shaped region 15 of the front side 12 covering the light-emitting diodes 14 to the front are provided with an inwardly reflecting layer 16.
  • This layer can be vapor-deposited, glued on or applied galvanically, so that the corresponding surfaces are mirrored in such a way that all the light is reflected on it and is reflected back into the interior.
  • the emitted light is bundled.
  • the shape of the front can vary, e.g. depending on the desired beam angle.
  • the rear side 17 of a radiator element 18 is formed in a cone inwards, with the circular cross section of the radiator element 18 essentially creating a circular cone with immersed side surfaces in the horizontal plane.
  • the light-emitting diodes 14 are arranged distributed over the circumference, in each case at the focal point of the reflector which is parabolic or elliptical in cross section and formed by the rear side 17. As shown schematically by light arrows, an essentially parallel light emission can be achieved in this way.
  • the emitter element 18 not only specifies the shape of the reflector, but is also a light guide element and holder for the light-emitting diodes 14.
  • the rear side 17 is provided with annular heat sinks 19 which fit into the conical indentation the back 17 are fitted.
  • annular heat sinks 19 can be used instead of ring-shaped heat sinks, which may possibly protrude beyond the conical indentation. Since light-emitting diodes have a very high luminous efficiency and relatively little heating, such heat sinks 19 are only required if the light-emitting diodes are arranged very densely and if the light-emitting diodes are very powerful.
  • Combinations of the two exemplary embodiments with regard to the shape of the front and rear of the emitter element are also possible, alternative shapes of the cross-sectional shape also being possible, depending on the manner in which the light is to be focused. With rectangular or oval light emitters and with light emitters with a different horizontal cross-sectional shape, variations in the shape of the front and back may be necessary.
  • the edge regions can also have a shape that differs from the exemplary embodiments in order to support the bundling of light and, for example, can have a concave cross section in order to support the light radiation into the center of the emitter element.
  • such light sources can also be used for other signal or lighting functions, for example for motor vehicle rear light combinations, that is to say combinations of rear light, brake light, reversing light and / or turn signals. These can be carried out separately, but can also be integrated in a light emitter. Different colored light emitting diodes are used to generate the different light colors required for this. Red LEDs are used for the rear light and brake light function and yellow LEDs for the turn signal function. A different number of light-emitting diodes can be activated to generate different brightnesses for the brake light and the rear light.
  • red, green and blue light-emitting diodes can be switched on at the same time, the light colors of which then add up to white light. If white LEDs are available, you can of course also use them directly. Furthermore, it is also possible to use other lighting elements that have comparable properties.
  • Light emitters with different colored light-emitting diodes can also be used to illuminate objects in advertising, in the show business, in the entertainment industry or the like. be used. Different lighting effects can be created with a single headlight.
  • the light-emitting diodes can also be used for special applications in pulse mode, for example for construction site lighting.
  • yellow light-emitting diodes are preferably used, it being possible to use up to twenty times the current intensity in the pulse mode in order to generate light flashes. Due to the low power consumption of light emitting diodes very small energy storage devices can be used on construction sites.
