Definitions

  • the present invention relates to a luminaire for room lighting and a method for producing such a luminaire.
  • Luminaires are known in a variety of designs and sizes. Luminaires are often optimized for a specific lighting task, so that different luminaires have to be used for different lighting tasks. By using several or different lights, the space requirement and the effort associated with the lights are increased, which can be undesirable.
  • the WO 2005/091254 A2 relates to a neon sign, which can be designed, for example, as a so-called edge front radiator.
  • the DE 20 2010 011 964 U1 relates to a wall shelf with an integrated LED strip.
  • a surface light is known which emits light upwards and downwards.
  • the WO 2004/051028 A1 relates to an illuminated tile that radiates upwards. Further lighting devices are from the KR 2015 0049093 A , the US 2014/211462 A1 , the US 2013/107519 A1 and the KR 2012 0132002 A known.
  • the object on which the invention is based is to specify a lamp which can be used for different lighting tasks, the lamp also being designed to be particularly compact.
  • a luminaire for room lighting which has a first and a second plate, each made of an opaque material.
  • a translucent material is arranged between the first plate and the second plate, at least in some areas.
  • one or more illuminants are arranged between the first and the second plate, which illuminants emit light through one or more recesses in the first and / or the second plate.
  • the distance between the first plate and the second plate is at least ten times smaller than the greatest extent of the first or second plate in one spatial direction.
  • the luminaire according to the invention is based on the knowledge that the arrangement of the illuminants between the first and the second plate and the use of the translucent material between the plates creates the possibility of using the illuminants to light both through the first plate (i.e. upwards, for example ), as well as through the second plate (that is, for example, downwards), as well as through the translucent material (that is, in the lateral direction).
  • the lamp according to the invention for example direct room lighting with light radiation downwards or indirect room lighting with light radiation upwards.
  • the light emerging from the side of the translucent material can also perform a guiding / guiding function, for example, which allows the shape of the luminaire to display the course of a path or a corridor in relatively dark rooms.
  • the luminaire according to the invention thus creates the possibility of emitting light - directed or controllable - in three different directions.
  • the lamp is very compact or flat, since the distance between the first and second plate can be very small compared to the other dimensions of the lamp.
  • first and the second plate can run parallel to one another and / or be congruent.
  • first plate can be set back at least in some areas with respect to the edge areas of the second plate, so that only the second plate is visible to a person standing below the second plate. This creates the impression of an extremely thin lamp.
  • the first and / or the second plate can also define a flat surface.
  • the size of the extension of the first or second plate in the longitudinal direction can define the length of the lamp and the width of the first or second plate can determine the width of the lamp .
  • the low height compared to the length or the width of the lamp results in a very flat and therefore compact lamp that nonetheless offers many different options for room lighting.
  • the first and / or the second plate can preferably be a metal plate, for example a steel plate, preferably an aluminum plate, for example with a maximum thickness of up to 5 mm, preferably of up to 1.5 mm or 0 , 5 mm.
  • the distance between the first plate and the second plate is at least one hundred times, preferably at least three hundred times, particularly preferably at least five hundred times, smaller than the largest expansion of the first or second plate in one spatial direction (the larger of the two plates being used in each case).
  • the distance between the plates can be less than 3 cm, preferably less than 1 cm, particularly preferably less than 0.6 cm being.
  • the luminaire can thus be designed to be particularly thin in order to achieve a small footprint, which is particularly advantageous in the case of low room heights.
  • the lamp can also have, for example, round, circular, arched, polygonal and / or elliptical contours.
  • Different contours can also be combined in one luminaire, for example in that the luminaire has a first rectangular section, which is adjoined by a partially annular section (which includes an angle of 90 °, for example). A second rectangular section can then in turn adjoin the partially annular section.
  • a lamp can be used, for example, to uniformly illuminate a corridor with a curve of 90 °.
  • the contours mentioned can be both inner and outer contours of the lamp.
  • the translucent material connects the first and the second plate.
  • the translucent material is preferably attached to at least 30%, more preferably to at least 50%, particularly preferably to at least 80%, in particular 100%, of the surface of the first and / or second plate.
  • the translucent material can hold the first and the second plate in their position relative to one another and thus ensure the mechanical stability of the lamp.
  • the translucent material extends at least in regions up to an edge of at least one of the plates, preferably up to Edge of both panels. More preferably, the translucent material, together with the edges of the first and second plates, forms a continuous edge of the lamp, at least in some areas. More precisely, an edge of the first and second plate can form a common plane with the edge of the translucent material.
  • the length of the lamp or the lamp contour is at least 15 times, preferably 30 times, particularly preferably 45 times, as great as their width.
  • the luminaire has a width between 20 and 200 mm, preferably between 30 and 100 mm, particularly preferably between 60 and 80 mm.
  • Such a lamp is particularly suitable for evenly illuminating corridors and for guidance by means of light.
  • the thickness of the translucent material is at least 3 times, preferably at least 8 times, particularly preferably at least 12 times greater than the thickness of the first and / or second plate. In this way, a particularly large lateral light outlet can be created.
  • the translucent material also preferably forms at least one closed space between the first and the second plate.
  • the closed space is not filled with the translucent material, the delimitation of the closed space being formed in particular by the first plate, the second plate and / or by the translucent material.
  • the lighting means for example, the lighting means, circuit boards for the lighting means, power supply units for operating the lighting means (i.e. electrical drivers), control electronics, connection lines for the lighting means, a user interface or the control electronics and so on can be arranged.
  • the translucent material can be, for example, polymethyl methacrylate (PMMA), polycarbonate (PC) or another translucent plastic Act.
  • PMMA polymethyl methacrylate
  • PC polycarbonate
  • the translucent material can also be a neutral, diffuse or white colored material.
  • other colors of the translucent material for example red, blue or green are also possible in order to generate a light emerging from the side that is colored independently of the color of the illuminant.
  • the lighting means comprise a first group of lighting means which exclusively emits light through cutouts in the first plate.
  • the lighting means of the first group thus emit light upwards, for example in the direction of a ceiling (so-called “uplights”). This enables the lamps in the first group to provide indirect room lighting.
  • the lighting means comprise a second group of lighting means which exclusively emits light through cutouts in the second plate.
  • the lighting means of the second plate thus emit light downwards (so-called “downlights”) in order to ensure direct room and / or object lighting.
  • the lighting means comprise a third group of lighting means which exclusively emits light through the translucent material.
  • the lighting means of the third group emit light to the side away from the lamp. Due to the very thin design of the luminaire, the exit surface of the light, i.e. the surface of the translucent material visible from the outside, is relatively narrow, giving the impression of a luminous edge (a "light edge").
  • the light edge can be used, for example, in emergency situations as a visualization of an escape route to be followed and the like. The light edge is suitable for this because of its elongated shape following the contour of the lamp.
  • the lighting means of the first and / or second and / or third group are attached to the first plate.
  • all of the lighting means used in the lamp can be mechanically attached to the first plate. This can simplify the manufacture of the lamp, since the second plate can be manufactured independently of the lighting means.
  • the light sources can be light emitting diodes (LEDs).
  • the first plate By attaching the lighting means to the first plate, the first plate can be in a thermally conductive connection with the lighting means.
  • the first plate can thus serve as a heat sink for the illuminants.
  • the first plate can also be used as a heat sink for electrical drivers to control the illuminants.
  • the electrical drivers are preferably current regulators.
  • the lighting means of the third group can be attached to the translucent material in such a way that a main direction of the light exit from the lighting means is aligned parallel to a direction of extent of the first and / or second plate. Efficient side lighting can be achieved in this way.
  • the lighting means of the third group fastened to the translucent material are preferably arranged in such a way that what is emitted by the lighting means Light first penetrates an air gap (e.g. 0.5 to 2 cm) before it penetrates the translucent material. In this way it is possible to prevent individual light sources from being recognized from outside the luminaire.
  • the lighting means of the first group are preferably chip-on-board LEDs (COB LEDs), a light-emitting surface of the COB LEDs preferably being arranged in recesses in the first plate.
  • COB-LEDs can have a flat light-emitting surface in which a multiplicity of individual LEDs are arranged, which in turn are covered, for example, by a phosphor material.
  • the flat light-emitting surface can preferably correspond to at least 80% or 90% of the surface of the recess in the first plate. Due to the arrangement of the light-emitting surface in a recess in the first plate, the radiation angle of the COB-LEDs is preferably not limited by the first plate.
  • the outer surface of the first plate and the light-emitting surface of the COB-LEDs can preferably lie in a common plane.
  • the COB LEDs can act as Lambertian radiators, with advantageously no color change of the emitted light occurring in the edge regions of the emission angle.
  • the surroundings can be illuminated homogeneously, in particular (indirect) illumination without a color fringing being able to be implemented.
  • secondary optics e.g. reflectors
  • Adapter boards which are arranged between a board of the COB LEDs and the first board, can be used to fasten the COB LEDs to the first plate.
  • the adapter boards can enable the COB-LEDs to be supplied with power, since the electrical connection surfaces of the COB-LEDs are often arranged on the side of the light-emitting surface of the LEDs. These connection surfaces are then covered by the first plate.
  • the adapter boards which can be made particularly thin (e.g. with a thickness of 50 to 300 ⁇ m), the COB LEDs can still be contacted.
  • the lighting means of the second group are LEDs, each of which includes secondary optics, preferably a reflector, the secondary optics preferably each adjoining a recess in the second plate.
  • the secondary optics can in particular be made of the translucent material.
  • the LEDs of the second group can consequently have their light-emitting surface closer to the first than to the second plate, wherein the distance between the light-emitting surface and the second plate can be bridged by the reflector. This offers the advantage that because of the recessed light-emitting surface of the LEDs of the second group and because of the reflector, glare of people can be reduced. This is particularly important for the lamps in the second group, as the second group provides direct room lighting.
  • the LEDs of the second group can for their part sit on carrier boards so that electrical connection lines can be better contacted.
  • the LEDs of the first and / or second and / or third group can preferably be controlled independently of one another.
  • the individual LEDs in a group can each be individually controllable.
  • By individually controlling the LEDs in a group e.g. a status or a movement (running light) can be displayed.
  • the luminaire is designed to keep the overall luminous flux emitted by the luminaire constant, the luminous flux emitted by individual illuminants changing over time, in particular by at least 10%, preferably by at least 50%, particularly preferably by at least 90%. .
  • a changing photo e.g. which one at suspended assembly is projected onto the ceiling and which, for example, can have the appearance of passing clouds.
  • some light sources can temporarily emit less light, while other light sources temporarily emit more light. This can increase the ability of people to concentrate in the vicinity of the lamp.
  • the latest biodynamic research results have shown that an unconsciously perceived optical stimulus can increase the ability to concentrate through locally modulated light without this being perceived as annoying. Accordingly, the luminaire can be designed for spatial and temporal modulation of the emitted light.
  • the LEDs of the first and / or second and / or third group can each comprise colored and / or RGB LEDs and thus emit light in different colors.
  • the luminaire can be controlled in a contactless manner (for example by gestures) or by touching the plates.
  • the luminaire can include sensors in the top and bottom, for example.
  • the sensors can in particular be time-of-flight sensors.
  • the sensors can in particular include SPAD elements (Single Photon Avalanche Diodes) and / or radar sensors.
  • SPAD elements Single Photon Avalanche Diodes
  • a short swipe on the top or bottom of the lamp can switch the light source on or off on the top or bottom of the lamp. It is also possible to convert a distance measurement from a controlling hand directly into a dimming value that causes the light to change in brightness.
  • a recess can also be provided in the translucent material, which in particular extends in the longitudinal direction of the lamp.
  • a support structure can be inserted into this recess, for example a metal carrier in an H-shape. The support structure can help stiffen the luminaire.
  • Recesses for a suspension device can also be provided in the first plate.
