Definitions

  • the invention relates to a luminaire for large-area lighting of walls or ceilings in rooms and of external facades in buildings according to the preamble of claim 1.
  • the lighting principle of the so-called wallwasher is rarely used for the illumination of rooms, actually only when art is to be illuminated.
  • the principle of the Wallwashers is that the wall (or the ceiling) is irradiated in large areas over a large area.
  • Such lights basically have a housing in which at least one lamp is arranged.
  • the disadvantage of these lights is that a large-scale lighting of walls or ceilings in rooms and outdoor facades in buildings with great variability is not possible.
  • the invention has for its object to provide a luminaire for large, variable illumination of walls or ceilings in rooms and external facades of buildings.
  • a lamp is created by means of which large-scale lighting of walls or ceilings in rooms and outdoor facades can be realized in buildings with a large variability.
  • the basic principle of the luminaire according to the invention consists in a kind of light line, d. H. a housing in the form of an elongated strip, which is only a few inches wide and high. This bar extends over a great length.
  • the housing can be mounted on the ceiling, as a ceiling structure or as a recessed ceiling version. Due to the use of LEDs, the luminaire stands out due to its high efficiency and low energy consumption for snow-white brightening of walls and ceilings, but also in all other variable light colors.
  • the walls can be illuminated in all the colors of the rainbow.
  • a lens disk which closes the housing on the front side, a targeted light emission of the LEDs is possible.
  • the lens disk always has the same cross-sectional shape over the length of the housing.
  • the luminaire according to the invention with its minimal dimensions and low energy input, creates an optimal, uniform illumination of the wall surface over the entire height of the room in great variability.
  • a colorful design of the walls is possible, from light pastel shades to bold colors across the entire spectrum of the rainbow.
  • the luminaire according to the invention can also be used for the night effect of buildings with little energy and light.
  • the housing is designed according to claim 3 as a one-piece profile. It is preferably an aluminum profile.
  • the housing on the outside cooling fins In order to better dissipate the heat generated by the LEDs, according to the embodiment in claim 4, the housing on the outside cooling fins.
  • the LEDs are arranged on a common board in the housing.
  • This primary lens is rotationally symmetrical and may, for example, substantially as a ball portion, in particular substantially be formed hemispherical.
  • the actual LED can he einshunt still have their own, integrated, upstream small lens.
  • the above-described primary lens or primary optics has nothing to do with this small lens.
  • the primary lens or primary optics forms the optical system together with the lens disk located in front of it.
  • a further preferred embodiment proposes according to claim 7. It states that the board is arranged in the region of one of the two inner longitudinal edges of the housing, so that the LEDs are aligned obliquely within the housing and radiate their light obliquely out of the housing.
  • a further preferred embodiment proposes claim 8 and relates to the special design of the lens or the lens disk.
  • the special design of the lens or the lens disk With the oblique arrangement of the LEDs on one side of the housing and the special design of the front lens disc ensures that the illuminated wall or ceiling is illuminated substantially uniformly over its entire surface.
  • the beam angle of the lamp can be varied.
  • This lens may be a kind of quasi-Fresnel lens.
  • the luminaire has a housing 1 in the form of a one-piece aluminum U-profile.
  • the housing 1 has in this case on the outside in the longitudinal direction extending cooling fins 2.
  • the housing 1 and the cooling fins 2 form a cooling profile.
  • FIGS. 2 and 3 show only short sections of the housing 1.
  • the housings 1 are usually much longer or a plurality of housings 1 are joined together in abutment, so that the entire housing extends substantially over the entire length of a wall.
  • the housing 1 In the interior of the housing 1 is a parallel to the inner longitudinal edge of the U-profile extending obliquely placed board 3. On this board 3, a plurality of LEDs 4 are arranged in series, so that they emit obliquely from the housing 1.
  • the open side of the housing 1 is closed by a lens 5 in the form of a lens plate.
  • this lens plate is inserted from the front side into the housing 1 in corresponding grooves.
  • the lens 5 has a special profiling in cross section. In the area of the LEDs 4, the lens 5 is convexly curved in cross-section towards the outside. This convex curvature then turns into a slight concave curvature on the other side. The interior of the housing 1 final side of the lens plate is flat compared.
  • a converging lens 7 is arranged in front of each LED 4. This is rotationally symmetrical in the form of a hemisphere and defines together with the lens 5 located in front (secondary lens), the optical system.
  • the LEDs 4 are preferably differently colored LEDs, which can be controlled by a corresponding electronics.
  • the light emitted by the LEDs 4 light is thrown by the converging lens 7 and by the plate-shaped lens 5 directed onto a wall 6.
  • the optical system is designed such that the wall 6 is illuminated over its entire height.
  • the lights with their housings 1 are executable in flexible lengths. As a result, a simple adaptation to the particular application is possible.
