Definitions
- the present invention relates to a luminaire for room lighting and a method for producing such a luminaire.
- Lights are known in a variety of embodiments and sizes. Frequently, luminaires are each optimized for a specific lighting task, so that different luminaires must be used for different lighting tasks. The use of several or different luminaires increases the space required and the effort associated with the luminaires, which can be undesirable. It is the object underlying the invention to provide a lamp which can be used for different lighting tasks, wherein the lamp should also be designed to be particularly compact.
- a lamp for room lighting which has a first and a second plate, which each consist of an opaque material.
- a translucent material is at least partially disposed between the first plate and the second plate.
- one or more light sources are arranged between the first and the second plate, which 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 largest extent of the first or second plate in one spatial direction.
- the luminaire according to the invention is based on the finding that the arrangement of the luminous means between the first and the second plate and the use of the translucent material between the plates makes it possible to use the luminous means both through the first plate (ie upwards, for example ), as well as through the second plate (that is, for example, down), as well as through the translucent material through (ie in the lateral direction) to emit.
- the luminaire according to the invention can be performed by the luminaire according to the invention, for example the direct room lighting with a light radiation downwards or the indirect room lighting with a light radiation upwards.
- the light exiting laterally from the translucent material it is also possible, for example, to fulfill a guiding / guiding function which makes it possible, in relatively dark spaces, to control the shape of the luminaire, e.g. to show the course of a path or a corridor.
- the luminaire according to the invention makes it possible to emit light - steered or controllable - in three different directions.
- the lamp is very compact or flat, since the distance of the first and second plate in comparison to the other dimensions of the lamp can be very low.
- the first and the second plate may run parallel to each other and / or congruent.
- the first plate can be set back, at least in places, with respect to the edge regions of the second plate so that only the second plate is visible from a person standing below the second plate. This can create the impression of an extremely thin luminaire.
- the first and / or the second plate can also define a flat surface. For example, if the first and the second plate congruent and each formed as an elongated rectangle, the size of the extension of the first and second plate in the longitudinal direction define the length of the lamp and the width of the first and second plate determine the width of the lamp ,
- the low height compared to the length or the width of the luminaire results in a very flat and thus compact luminaire which nonetheless offers many different possibilities for room lighting offers.
- the first and / or the second plate may 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, more preferably at least five hundred times, smaller than the largest extent of the first or second plate in one spatial direction (each larger the two plates is used). If, for example, the first and second plates have a rectangular contour with a length of 300 cm and a width of 10 cm, the distance between the plates may be less than 3 cm, preferably less than 1 cm, particularly preferably less than 0.6 cm.
- the lamp can thus be designed to be particularly thin in order to realize a small footprint, which is particularly advantageous at low room heights.
- the luminaire may also have, for example, round, circular, arcuate, 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, to which a part-annular section connects (which for example encloses an angle of 90 °).
- a second rectangular section can then adjoin the partially annular section.
- Such a lamp can be used as example for the uniform illumination of a corridor with a curve of 90 °.
- the contours mentioned may be both internal and external contours of the luminaire.
- the translucent material connects the first and the second plate.
- the translucent material is preferably attached to at least 30%, more preferably at least 50%, particularly preferably 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 against each other in their position and thus ensure the mechanical stability of the lamp.
- the translucent material at least partially extends to an edge of at least one of the plates, preferably to the edge of both plates. More preferably, the translucent material forms together with the edges of the first and second plate, at least partially, continuous edge of the lamp. More specifically, an edge of the first and second plates may form a common plane with the edge of the translucent material.
- the length of the lamp or the luminaire contour is at least 15 times, preferably 30 times, particularly preferably 45 times, as large as the width thereof.
- 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 uniform illumination of corridors and 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 forms at least one closed space between the first and second plates.
- the enclosed space is not filled with the translucent material, wherein the boundary of the closed space is 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 (ie electrical drivers), a control electronics, connecting lines for the lighting means, a control interface or the control electronics and so on ,
- the translucent material may be, for example, polymethyl methacrylate (PMMA), polycarbonate (PC) or another translucent plastic.
- PMMA polymethyl methacrylate
- PC polycarbonate
- the translucent material can also be a neutral, diffuse or white-colored material.
- other colors of translucent material e.g., red, blue, or green are possible to produce a laterally outgoing light colored independently of the color of the illuminant.
- the lighting means comprise a first group of lighting means, which, in particular exclusively, emits light through recesses of the first panel.
- the bulbs of the first In this way, groups of light can emit light upwards, for example in the direction of a ceiling (so-called "uplights").
- the lamps of the first group can provide indirect room lighting.
- the lighting means comprise a second group of lighting means which, in particular exclusively, emits light through recesses of the second plate.
- the light sources of the second plate can thus emit light downwards (so-called “downlights") in order to provide direct room and / or object illumination.
- the lighting means comprise a third group of lighting means, which, in particular exclusively, emits light through the translucent material.
- the bulbs of the third group can emit light away from the side of the lamp. Due to the very thin design of the lamp, the exit surface of the light, that is, the visible from the outside surface of the translucent material, relatively narrow, so that the impression of a luminous edge (a "light edge") results.
- the light edge can serve, for example, in emergency situations as visualization of an escape route to be followed and the like.
- the light edge is suitable for this purpose due to its elongated shape following the contour of the luminaire.
- one or two groups of illuminants is / is present, which emits both light through the first plate and / or the second plate and / or through the translucent material.
- the lighting means of the first and / or second and / or third group are attached to the first plate.

- the first plate can be used as a heat sink for electrical drivers for controlling the light sources.
- the electrical drivers are preferably current regulators.
- the lighting means of the third group may 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 an extension direction of the first and / or second plate.
- efficient lateral lighting can be achieved.
- the light sources of the third group attached to the translucent material are preferably arranged so that light emitted by the light sources first penetrates an air gap (for example 0.5 to 2 cm) before it penetrates into the translucent material. In this way, detection of individual bulbs from outside the light can be prevented.
- the lighting means of the first group are chip-on-board LEDs (COB LEDs), wherein a light-emitting surface of the COB LEDs is preferably arranged in recesses of the first panel.
- COB LEDs can have a flat light-emitting surface, in which a plurality of individual LEDs are arranged, which in turn are covered, for example, by a phosphor material.
- the level The light-emitting surface may preferably correspond to at least 80% or 90% of the area of the recess in the first plate. Due to the arrangement of the light-emitting surface in a recess of the first plate, the emission 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 may preferably lie in a common plane.
- the COB LEDs can act as Lambertian radiators, wherein advantageously no color change of the emitted light occurs in the edge regions of the emission angle. In this way, a homogeneous illumination of the environment can be done, in particular, a (indirect) illumination without color fringe can be realized reali.
- secondary optics eg reflectors
- the adapter boards can be used, which are arranged between a board of the COB LEDs and the first Plat te.
- the adapter boards can provide power to the COB LEDs since the electrical pads of the COB LEDs are often located 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 may be particularly thin (for example with a thickness of 50 to 300 pm), a contacting of the COB LEDs can nevertheless be realized.
- the light sources of the second group are LEDs which each comprise a secondary optic, preferably a reflector, the secondary optic preferably each connecting to a recess of the second plate.
- the secondary optics can in particular be made of the translucent material.
- the LEDs of the second group may thus have their light-emitting surface closer to the first than to the second plate, the distance between the light-emitting surface and the second Plate can be bridged by the reflector. This offers the advantage that due to the recessed light-emitting surface of the LEDs of the second group and due to the reflector, dazzling of persons can be reduced. This is particularly important for the bulbs of the second group, since the second group provides the direct room lighting.
- the LEDs of the second group can in turn sit on carrier boards in order to be better contacted with electrical connection lines can.
- the LEDs of the first and / or second and / or third group are independently controllable from one another.
- the individual LEDs of a group can each be controlled individually.

- FIGS. 2a and 2b show the luminaire 10 described above, each in a perspective view from above. It will be appreciated that the electrically conductive suspensions 34 and the apertures (i.e., the light emitting surfaces 36) for the uplight LEDs 16 are mounted on top of the fixture 12.
- Fig. 3a shows a shelf 40 in a perspective view.
- the shelf 40 includes a rear wall 42, wherein in the rear wall 42, two parallel slots 44 are arranged. In each of the slots 44, a lamp 10 is inserted, so that the lamp 10 serves as a shelf.
- the uplight LEDs 16 and the downlight LEDs 18 can illuminate objects arranged on the shelves in a simple manner.
- the shelf 40 is shown in a side sectional view.
- contacts 46 are attached to the lamp, which fix the lamp 10 in the rear wall 42.
- an energy transfer to the lamp 10 can also take place.
- the downlight LED 18 shown in Fig. 3c can be operated.
- a plurality of downlight LEDs 18 or a downwardly radiating light band can also be arranged in the light 10.
- the light band can be provided for example by uniformly arranged additional LEDs 20, which radiate through a recess in the first or second plate 12, 30.
