Definitions

  • the present invention relates to a luminaire with a grid, which has openings provided for the emission of light.
  • rod-shaped light sources such as fluorescent tubes.
  • the use of fluorescent lamps ensures a high light output with a relatively low energy consumption.
  • such a grid lamp consists of an elongated lamp housing, which has lamp holders for holding and electrical connection of at least one elongate lamp in its end regions.
  • the housing which also usually also an operating device for the lamp - for example, an electronic ballast - receives, has in its lower part further holding elements, with the aid of a luminous grid seen in the emission can be arranged and fixed in front of the lamp.
  • the grid is usually a one-piece element, which is snapped onto the underside of the lamp housing or on the fastening or holding means provided there.
  • Gas discharge lamps in particular the fluorescent lamps mainly used for normal room lighting are available in different lengths.
  • luminaires of the same type in each of which a lamp of different lengths can be used, it is necessary to provide luminaire housing and luminaire grid in the corresponding lengths, the production of these elements in different lengths, however, associated with an increased cost is.
  • the grid is formed by a plurality of individual modules, which are assembled into an elongated luminaire grid. Due to the number of modules used, the length of the entire grid can also be influenced in a simple manner.
  • the present invention is therefore based on the object of specifying a cost-effective alternative to the production of luminaires of the type described above. At the same time, however, the luminaires should look appealing and have a very high-quality effect.
  • the luminaire according to the invention has means for holding and for electrically connecting a tubular lamp and a plurality of grid modules arranged in front of the lamp, viewed in the emission direction, which have respective passage openings provided for the emission of light.
  • the grid modules are arranged one behind the other to form an elongated luminaire grid and held together by holding elements, wherein according to the invention the holding elements are formed by profile elements which can be snapped onto the grid modules in the form of connecting profiles.
  • the solution according to the invention provides for a luminaire grid to be formed from a plurality of individual grid modules which, taken on their own, are relatively short and are arranged or assembled together to form the grid of suitable length.
  • This makes it possible to provide only a single raster module of a given length available, which is assembled with several similar modules to light grids in the desired lengths.
  • grid modules with a length of 300 mm can be provided, which are assembled to the usual lengths of 600, 1200 and 1500 mm.
  • the costs can thereby be considerably reduced because only a single tool is required for the raster modules, which are preferably produced by plastic injection molding. The considerable cost of tools in further lengths can be saved by the present invention.
  • the holding together of the various grid modules to a single luminaire grid is carried out according to the invention by means of laterally alsschnappbarer profile elements.
  • profile elements can be very slim and are stabilized in conjunction with the grid modules, so that the overall result is a very stable arrangement.
  • the profile elements can even replace the usually required luminaire housing, whereby further costs can be saved.
  • the assembly of a plurality of modules into a single luminaire grid via the lateral snap-fastening of the profile elements can take place much more easily and quickly.
  • the luminaire can also be used for indirect lighting, ie a part of the light emitted by the lamp is emitted against the main light emission direction to the top, for example, to lighten the ceiling.
  • the use of only laterally aufschnappbaren profile elements even particularly advantageous because in contrast to a conventional luminaire housing, which is usually designed in section U-shaped, no partial holes must be stamped or milled into the housing bottom, which the allow indirect light emission.
  • the supply and removal of electrical lines is simplified by the use of only laterally disposed profile elements.
  • the individual grid modules assembled to form the luminaire grid preferably consist - as already mentioned - of plastic. This has the consequence that the individual modules can expand and contract slightly as a result of the temperature differences that occur. This could create a narrow gap between the grid modules, can escape through the light, which affects the visual appearance of the lamp.
  • the grid modules according to the invention are compressed by provided at the longitudinal ends of the luminaire grid frontal springs, by elastic bands or the like in the longitudinal direction. This ensures that the individual raster modules still abut each other even after temperature fluctuations and no unwanted light emission takes place.
  • the holding together of the raster modules by the lateral profile elements according to the invention is preferably carried out with the aid of guide grooves and / or snap lugs, which allow a locking of the individual elements together.
  • the profile elements can have a greater height than the grid modules themselves, which above the luminaire grid is formed by a space enclosed by the profile elements or laterally covered space, which can be used for example for receiving lamp operating devices.
  • Another possibility is to form the lateral profile elements in cross-section U-shaped, which in addition to the luminaire grid a space is created in the corresponding lamp operating devices can be arranged.
  • the luminaire has two laterally juxtaposed light grids of the type described above, which are connected to one another via a connecting profile arranged therebetween. Overall, therefore, the possibility is created to produce a grid lamp in a very simple and inexpensive manner.
  • Another advantageous development of the present invention relates to the design of the individual raster modules.
  • these each have a longitudinally extending back reflector, which is intended to reflect a part of the light emitted by the lamp against the emission direction.
  • passage openings are arranged in the back reflector, which are intended to pass a part of the light emitted by the lamp in the emission direction.
  • pot reflectors can be connected to these openings.
  • the basic idea of this particular embodiment of the individual grid modules is to emit the light of a single tubular lamp via a plurality of light exit openings, followed by cup-shaped reflectors.
  • the impression of a series arrangement of individual halogen beams is achieved, whereby the lights are given a particularly high-quality appearance.
  • a variety of appealing lighting effects can be achieved.
  • a corresponding grid module is characterized by its simple structure, since the arrangement consisting of the back reflector and the pot reflectors can be formed in one piece, which - as already mentioned above - is achieved in that the grid modules are produced by injection molding.
  • the pot reflectors are connected to each other at their edge regions via a connecting plate arranged parallel to the lamp, wherein the connecting plate may also be integrally connected to the reflectors or the entire Räserermodul.
  • the connecting plate itself is designed to be transparent. Namely, when a part of the light emitted from the tubular lamp is directed into an area outside the pot reflectors, the structure thereof can be recognized by the transparent connecting plate.
  • the introduction of the light into the area outside the pot reflectors can be achieved, for example, by virtue of the fact that the back reflector is at least partially translucent. It is also possible to color the back reflector in its transparent areas, so that the connection plate appears in a changed color.
  • the pot reflectors can protrude with their light exit openings on the connection plate or ends flush with this.
  • the rear reflector is preferably designed such that it at least partially surrounds the lamp. In particular, it can be semicircular, as seen in cross-section.
  • Another advantage of the specially designed raster modules is also that part of the light emitted by the lamp is used for indirect illumination.
  • it could be provided to provide on the side opposite the pot reflectors side of the lamp, a Abblend- or filter plate over which a part of the output from the lamp Light is directed to the ceiling of the room to be illuminated.
  • the edge regions of this screening or filter plate can be designed to be reflective in order to allow the deflection of part of the light into the space surrounding the pot reflectors. Again, it is possible to make the translucent area of the screening or filter plate colored and thus to make the ceiling area appear above the lamp in a different color.
  • FIGS. 1 to 12 initially show basic options for designing a grid lamp. Furthermore, a particularly preferred embodiment of a raster module is described.
  • Lamp 1 shown in section consists essentially of a tubular elongated lamp 2, which is preferably a fluorescent lamp, as well as one of three grid modules 3 connected in series and arranged in the emission direction laterally or in front of the lamp 2 luminaire grid.
  • the luminaire grid or the raster modules 3 are each formed by a semi-circular semi-reflector 4 extending in the longitudinal direction of the lamp 2, from which several pot reflectors 6 with a circular light exit opening 7 extend in the emission direction.
  • the lamp 2 is arranged inside the semicircular longitudinal reflector 4.
  • the pot reflectors 6 adjoin passage openings of the back reflector 4, so that part of the light radiated by the lamp 2 is directed downward via these passage openings and the pot reflectors 6.
  • the pot reflectors 6 thus serve for direct illumination of the area below the lamp 1 and have a shape by which the light emitted by the lamp 2 down to a predetermined exit angle is limited. Since dazzling effects are avoided in this way, the luminaire 1 according to the invention can be used in particular for room lighting in office workplaces.
  • This operating device 11 may in particular be an electronic Ballast for operating a gas discharge lamp, in particular a fluorescent tube act on the representation of the versions for holding and electrical connection of the lamp 2 has been omitted for reasons of clarity.
  • the side boxes 10 serve the side boxes 10 as holding elements also to hold the successively arranged grid modules 3 to the luminaire grid.
  • the attachment of the two side boxes 10 to the grid modules 3 takes place in the illustrated example with the aid of side bars 9, which protrude from the outer sides of the rear reflector 4, and a parallel to these side bars 9 arranged connecting plate 8.
  • This connecting plate 8 connects the pot reflectors 6 at their edge regions , wherein the pot reflectors 6 project slightly with their light exit openings 7 with respect to the connecting plate 8.
  • the connecting plate 8 and the side bars 9 also serve to generate special lighting effects, as will also be explained later.
  • part of the light emitted by the lamp 2 is also directed upwards via the back reflector 4 and accordingly serves for indirect room lighting.
  • the lighting properties of the lamp 1 can be adapted to external conditions.
  • a raster module 3 with the back reflector 4 and the pot reflectors 6 is preferably formed by a single part, which is produced for example by injection molding.
  • the raster module 3 can be produced in the ideal case with a simply designed, slide-less mold, with more complex structures, the workpiece is removed by means of a sliding technique.
  • the connecting plate 8 is part of this one-piece plastic part, which in an enlarged view in the FIGS. 3 and 4 is shown.
  • the underside of the back reflector 4 has a plurality of openings 5, to which the pot reflectors connect 6, which in turn are connected in their end regions on the approximately 1 - 2 mm thick connecting plate 8.
  • the pot reflectors 6, which are provided with a reflection layer at least on their insides, preferably have a size corresponding to the usual halogen lamps of approximately 40 to 60 mm in diameter.
  • the inside of the pot reflectors 6 can be provided to make the inside of the pot reflectors 6 faceted.
  • the production of the individual facets takes place already during the production of the plastic part during the injection molding and is achieved by an appropriate design of the molds.
  • the application of the reflection layer is preferably carried out by vapor deposition of an aluminum coating in a high vacuum.
  • Particular lighting effects can be generated in the luminaire 1 with the preferred raster modules 3, characterized in that the different areas of the raster modules 3 are formed differently reflective or translucent. This will be explained below with reference to FIGS. 5 and 6 that have two variants of in FIG. 1 illustrated lamp 1 show are explained.

  • This brightening of the outer sides of the pot reflectors 6 is achieved in that the back reflector 4 is at least in its upper regions teillicht devisage so that a portion of the light emitted by the lamp 2 light can pass through the back reflector 4.
  • This light thus falls in a light chamber, which is bounded by the side wall of the rear reflector 4, the pot reflectors 6, the connecting plate 8 and additional reflectors 12 on both sides of the pot reflectors 6.
  • the light entering the light chamber can leave it via the connecting plate 8 again, so that the outside of the pot reflectors 6 can be seen.

  • Fig. 19 variant shown is to use a profile part 20, which has both sides arranged snap arms for latching with raster modules 3. This makes it possible to form on both sides of the central profile element 20 lighting grid and accordingly to realize two- or multi-lamp lights.
  • corresponding grooves are provided in the raster modules to receive corresponding covers. These grooves can also be provided to snap receiving elements - for example, bow-like spring elements - for mounting the lamp to a ceiling.
  • the luminaire according to the present invention is thus distinguished by its simple construction, which makes it possible to provide luminaires in different variants and lengths by means of slight changes to the individual components. At the same time optically extremely appealing lighting effects can be achieved and the lamp can be given a high-quality appearance.
