Definitions

  • the invention relates to a reflector luminaire with a plurality of light-emitting diodes arranged in a flat manner, each of which is arranged in the center of a reflection surface.
  • Light-emitting diodes with a wide beam angle which emit the light emitted by them over a wide area via associated reflectors. Such light-emitting diodes can be arranged in a large number in one area in order to form a correspondingly large illuminated field.
  • the light-emitting diodes are usually arranged in the center of a reflector housing, the light being emitted across the width of the reflector.
  • a reflector housing Such reflectors can be made of metal, but there are also plastic reflectors in round and square designs.
  • a row of several reflectors means that one does not reach an overall luminous area, but only a larger area, which is composed of individual, separate luminous areas.
  • a reflector luminaire of the type mentioned at the outset is known, in which the respective light box receiving the light-emitting diodes has a certain size in accordance with the intended use and, accordingly, can only accommodate a intended number of light-emitting diodes. To enlarge the lighting area, it is provided to arrange a corresponding number of lighting boxes next to one another.
  • the object of the invention is to provide a reflector lamp of the type mentioned, the size of which easily to the required dimensions is adaptable without creating an interrupted illuminated area.
  • a housing is provided for each light-emitting diode, the front of which forms the associated reflection surface, through which a major part of the light emitted by the associated light-emitting diode is emitted essentially perpendicularly, the housing being adapted to the object to be illuminated Number to a block consisting of one or more rows are arranged assembled in a frame which forms a circumferential, opposite to the reflecting surfaces a circumferential, raised against this reflecting surface, by the falling on it, emerging laterally from the light emitting diodes, not reflected by the reflecting surfaces essentially is radiated vertically.
  • the housings forming the front surface of the reflection surface formed in such a way that the reflective surfaces are kept so low that the light that emerges laterally from the light-emitting diodes is only partially reflected by the respective reflective surfaces, while a further part of this laterally emerging light propagates into the space above the adjacent reflective surfaces and partially strikes the reflection surfaces of the peripheral frame, from where it is then also radiated essentially perpendicular to the main plane of the radiating surface.
  • Square reflection surfaces are used, the surface of which is fully illuminated by the respective light-emitting diode.
  • Fig. 1 shows a reflector lamp in section.
  • Fig. 2 shows in perspective a reflector lamp partially assembled.
  • FIG. 3 shows sections of a further embodiment for a housing for light-emitting diodes.
  • the reflector lamp has cube-shaped housing 1 made of plastic, which have reflecting surfaces 2 on the front.
  • the reflection surfaces 2 are formed in the illustrated embodiment by a pyramid-shaped recess on the front of the housing 1, so that four identical, essentially triangular surfaces are formed, which are mirrored, for example, by metallization.
  • In the center of the reflection surface 2 there is a receiving opening 3 for a light-emitting diode 4, which extends in steps to the bottom of the housing 1, so that a light-emitting diode 4 can be used in such a way that its base part sits in the receiving opening 3, its light-emitting part accordingly the receptacle opening on the front and its connecting contacts 5 protrude from the housing 1 on the back.
  • the housings 1 have pins 6 on two side faces and pin receptacles 7 on the two other side faces, in each case on adjacent side faces.
  • the housing 1 can be assembled into single-row or multi-row blocks, the dimensions of such a block being readily adaptable to the particular intended use.
  • the reflection surfaces 2 can also be designed as small concave mirrors be.
  • the light-emitting diodes 4 can also be inserted from below into a correspondingly designed receiving opening 3 in the housing 1, as shown in FIG. 3.
  • the block formed from a plurality of housings 1 is surrounded by a frame 8 which consists of four miter-cut frame strips 9 which protrude from the radiating surface and form a circumferential raised reflection surface 10.
  • the frame 8 is also made of plastic, corresponding to the pin 6 of the housing 1 pin recesses 7a or corresponding to the pin recesses 7 of the housing 1 pin 6a, via which it is connected to the block formed from the housing 1, that is, that two adjacent to each other Frame strips 9 are provided with pins 6a and the other two with pin receptacles 7a in a grid corresponding to the pins 6 and pin receptacles 7 of the housing 1.
  • the pins 6, 6a and pin receptacles 7, 7a preferably have non-circular cross sections in order to create a connection that is secure against rotation.
  • the frame strips 9 are provided adjacent to the reflection surface 10 with a circumferential groove 11 for receiving a diffuser plate 12.
  • the reflecting surfaces 2 extend at a relatively flat angle, e.g. at about 45 ° with respect to the base of the housing 1 from the receiving opening 3 to the outside, while the reflection surface 10 of the frame strips 9 at a much steeper angle, e.g. about 60 ° to the base surface of the housing 1, the reflection surface 10 of the respective frame strip continuing the reflection surfaces 2 of the adjacent housing 1.
  • the latter also leads to a bundled light emission in the edge region, so that the diffuser plate 12 is illuminated homogeneously.
  • the reflector lamp is produced by first forming rows from the housings and forming a corresponding block by joining these rows, after which three correspondingly long frame strips 9 are inserted laterally onto the block, after which the diffuser plate 12 is inserted into the groove 11 and then the fourth frame bar 9 is plugged on.
  • the connecting contacts 5 of the light-emitting diodes 4 inserted into the receiving openings 3 are arranged in a grid in such a way that they are easy to put on the reflector lamp is made possible on a correspondingly prepared circuit board 13.
  • the housings 1 are expediently provided on the bottom with spacers 14, so that a degassing zone is formed between the reflector lamp and the printed circuit board 13.
  • Such a reflector lamp is particularly suitable for front panel installation, for which purpose a circumferential recess 15 can be provided on the frame 8, which receives the edge of a corresponding recess in a front panel 16, so that the reflector lamp is flush with the front panel 16 by fitting can be mounted from the outside or by inserting the reflector light from behind.
  • the individual elements form a modular system of uniform components for any shapes and sizes of rectangular reflector lights.
