Definitions

  • the invention relates to a lighting device for attachment to a building wall.
  • the lighting device of the type considered here is intended to be attached to a building wall.
  • the building wall can be a floor, ceiling or side wall of a room, a building or a piece of furniture, as well as a wall of an outside area of a building.
  • the lighting device according to the invention can in particular serve as a ceiling cladding, for example in elevators or showers, as a shower partition or also as a kitchen cladding or for furnishing living spaces.
  • Lighting devices of the aforementioned type are known, for example from JP2002063804 A , the US 2014/036494 A1 , the US 2014/055995 A1 , the DE 102013211206 A1 , the EP 2722454 A1 and the US 2013/141906 A1 .
  • they are used to design the room or to illuminate the respective room.
  • By designing the lighting devices by selecting different types of LEDs it is possible to achieve different design effects within the rooms. This is usually caused by the fact that different types of LEDs are used. For example, the different selection of LEDs or the combination of different LEDs can cause a change in the luminous colors and thus in the appearance.
  • the object of the present invention is to create a lighting device for attachment to a building wall, with which various optical effects can be achieved due to its design, for example an optical enlargement of the room, and at the same time requires little technical effort.
  • the object is achieved by a lighting device according to claim 1.
  • a lighting device for attachment to a building wall which brings about an optical enlargement of the respective room with little technical effort.
  • This is brought about by the fact that the LED, due to its strip-like design and its attachment to the frame of the device, illuminates the structured surface of the reflector film over a large area.
  • the structure of the surface creates an effect that simulates, for example, a dome-like or pointed roof-shaped design. This gives the viewer the impression that, in the case the attachment of the lighting device to the ceiling, a higher room height than the actual room height is suggested.
  • the lighting device is attached to vertical walls, an optical enlargement of the depth of the room is simulated. In this way, the feeling of space when looking at the lighting device is improved, so that small spaces appear larger. This reduces the risk of claustrophobic conditions.
  • the use of a film for the reflector also results in an extremely low overall height of the lighting device. Because of the comparatively low technical complexity, the costs for the lighting device are low.
  • the reflective surface is formed by an aluminum foil.
  • an aluminum foil offers the advantage of very simple assembly.
  • the aluminum foil can easily be produced in a wide variety of dimensions, so that the reflective surface can be easily adapted to the base of the building wall.
  • the reflective surface is glued to the rear wall of the lighting device. Gluing the reflective surface offers a very simple and therefore inexpensive and quick installation option.
  • the LEDs are arranged on frame profiles that are connected to the mounting frame. This type of assembly also enables very simple assembly of the LED.
  • the frame profiles offer the advantage of laying the cabling required for the electrification invisibly between the mounting frame and the frame profiles.
  • Selected lighting device for attachment to a building wall has a square base.
  • the lighting device has the shape of a trapezoid.
  • the lighting device comprises a mounting frame 1, which in the exemplary embodiment according to Figure 1 has a square education. Other shapes, for example rectangular, trapezoidal or triangular, etc. are also possible.
  • the size and shape of the mounting frame 1 depends on the respective installation conditions in which the lighting device is to be installed.
  • the mounting frame 1 is overlapped in some areas by a frame 2, which in the exemplary embodiment is made from an aluminum profile. Other materials for the frame 2 can also be used.
  • the mounting frame 1 has a rear wall 3.
  • the frame 2 On its (view) side facing away from the rear wall 3, the frame 2 is provided with a transparent pane 4.
  • the pane can be made of ESG or VSG glass. It can also be made of polymethyl methacrylate (PMMA), which is also known as acrylic glass. It is a synthetic, transparent and thermoplastic plastic that, while being light, has optical properties that are comparable to normal glass.
  • PMMA polymethyl methacrylate
  • More than one LED is arranged in the mounting frame 1 and is designed in the manner of a bar 5.
  • the LEDs can also be used as strips (not according to the invention).
  • the LEDs preferably have a height of approximately 10 mm.
  • LED strips 5 on two sides of the mounting frame 1 LED strips 5 arranged;
  • LEDs can also be provided on all sides (not according to the invention).
  • the LEDs can be RGB LEDs, for example, in which colored light can also be produced by appropriate control of the individual light-emitting diodes and with which smooth color transitions are possible are.
  • the LED strips 5 are fastened to frame profiles 6 which, in the exemplary embodiment, are connected to the mounting frame 1 by screws 8.
  • the attachment can also take place by gluing, clamping or the like.
  • the electrification required for the operation of the lighting device is not visible between the frame profiles 6 and the mounting frame 1.
  • the cabling is led out of the lighting device through a hole - not shown - in the rear wall 3 of the lighting device and connected to the electrical installation of the respective building.
  • the lighting device can either be actuated by a conventional light switch or also be provided with a receiving module in order to carry out the actuation with the aid of a remote control.
  • a transformer is provided which converts the mains voltage of the respective building installation to the voltage necessary for the operation of the lighting device according to the invention.
  • the reflector foil is an aluminum foil.
  • the reflector foil has a low material thickness; In practice, a material thickness of 0.55 mm has proven to be particularly suitable.
  • the reflective surface 7 is glued from the inside onto the rear wall 3 of the mounting frame 1.
  • a clamping device if necessary, screwing to the rear wall 3 is also possible.
  • the reflective surface 7 embodied as a reflector film has a structured surface at least on its side facing the pane.
  • the structure of the surface can vary depending on the desired optical effect be designed.
  • the structure is rib-shaped. Ribs extend over the entire film and are aligned parallel to one another. In this case, the ribs are aligned parallel to two sides of the surface 7.
  • the distance between the ribs is the same over the entire reflective surface 7.
  • the spacing between the ribs can vary. There is also the possibility of aligning the ribs parallel, but diagonally to the reflective surface 7. It is also possible to break through the ribs.
  • the structure can also be aligned in an arc or also in a circle.
  • the structure can also be designed in the manner of a master carre design known from window technology.
  • the differently designed structures of the reflective surface 7 make it possible to achieve different lighting effects.
  • a wide variety of optical effects for example dome-like designs or pointed roof-like designs, can be produced.
  • the design of the LED in the form of strips and their attachment to the frame of the device ensures that the structured surface of the reflector film arranged on the rear wall of the mounting frame is illuminated over a large area. This is ensured by the greater height of the LEDs compared to the foil.
  • the light beams emitted by the LEDs are reflected by the structured surface of the reflector film.
  • the surface structure selected in each case enables various optical effects to be achieved, for example a dome-like or pointed roof-shaped design. But wave-shaped, circular, oval or other designs can also be implemented.
  • the invention offers the possibility of changing the visual design of a room through the lighting.
  • an optical increase in the respective room can be brought about, which leads to an improved feeling of space, especially in elevators.
  • the use of the film for the reflector also results in a very low overall height of the lighting device according to the invention.
  • the lighting device is therefore also for the Suitable for retrofitting on building walls, for example for retrofitting on the ceilings of existing elevators.
  • the use of foil makes it possible to cut it to the desired size of the lighting device. This enables the lighting device according to the invention to be produced very inexpensively.
  • the lighting device also offers the possibility of influencing the room design by using different colored LEDs. There are hardly any limits to the type of variations.
