Definitions

  • the present invention relates to a luminaire according to the preamble of claim 1.
  • FIG. 14 A luminaire of this type, as described for example in DE 44 43 916 A1, is shown in FIG. 14.
  • a raster reflector 26 consisting of side reflectors and transverse slats is arranged, with the aid of which most of the light emitted by the lamp 21 is directed and emitted downwards without glare.
  • the use of such a raster reflector 26 is advantageous, for example, in luminaires in offices with multiple VDU workstations, since the downwardly radiated light is to some degree cross-faded and therefore can not cause reflections on the screens.
  • the lamp shown in Fig. 14 further comprises a concave curved outer reflector 22, on which the light emitted from the lamp 21 laterally or upwardly falls.
  • the area surrounding the lamp 21 and the raster reflector 26 is additionally illuminated, which, on the one hand, makes it possible to detect in a simple manner whether the luminaire is actually switched on or not, but on the other hand is perceived as much more pleasant by a viewer than the light of a pure grid lamp, in which the entire light is emitted only downwards, so that the ceiling area itself appears dark.
  • the luminaire according to the invention has a tubular gas discharge lamp, at least one concave curved reflector arranged next to the lamp as well as at least one - likewise viewed from the area to be illuminated - next to the lamp but arranged in front of the reflector at least partially transparent diffuser.
  • the diffuser and the reflector define next to the lamp at least one light entrance surface and converge at their end remote from the lamp such that they include at least one light chamber.
  • the ratio between the width of a light chamber and the height of the light entry surface is at least 4: 1; wherein the height of the light entry surface is understood to mean the distance between the reflector and the diffuser present in this region. This measure has the consequence that the lamp can be designed significantly flatter overall and also gives the opportunity to give the lights a completely new look.
  • the ratio of the width of a light chamber to this largest distance is at least 4: 1.
  • the ratio of the width of a light chamber to the height of the light entry surface or to the largest distance between the reflector and the diffuser is between 4: 1 and 5: 1.
  • the light entry surfaces for the light chamber or light chambers are also formed by diffusers.
  • the light entry surfaces are formed such that a higher proportion of the light emitted by the lamp into a light chamber is directed to more remote areas of the reflector.
  • the above-mentioned and the light entry surfaces forming diffusers may have a different light transmission, or it is possible in the light entry surfaces optical elements - such as prismatic structures or The like - to install, which direct the light in the desired manner on the reflector.
  • the surface of the reflector is also diffusely reflective, but it may also be designed such that areas located farther from the lamp have a higher reflectance than areas near the lamp, which also aids in equalizing the luminance.
  • Another measure may be that also the diffuser arranged in front of the reflector has a light transmittance dependent on the distance to the lamp.
  • a light distribution element e.g. a grid consisting of side reflectors and cross blades can be arranged.
  • Other optical elements would be conceivable, which cause a more interesting appearance of the entire lamp, such as a teillicht fashion emergees perforated plate or the like.
  • the lamp can also consist in that the reflector arranged laterally from the lamp is itself part-leak-permeable. It is then possible to arrange further light sources behind this partial translucent reflector which can be used to achieve special lighting effects. On the other hand, in this case, a lying above the light ceiling area can be brightened.
  • the reflector is part-permeable to light
  • another refinement can also be to arrange another reflector behind the reflector, so that in each case a further light chamber is formed behind the light chambers.
  • additional light sources within these further light chambers, which can be controllable for example in their color and brightness.
  • This may be, for example, controllable light-emitting diodes (LEDs).
  • LEDs controllable light-emitting diodes
  • the formation of this additional light chamber or light chambers can also be carried out independently of the above delivered size ratio for a light chamber and is the subject of claim 18.
  • optical elements are arranged within the light entry surfaces, which are a color change of the light which has become on the reflector cause the area surrounding the lamp to appear in a slightly different color.
  • the luminaire according to the invention can be used in several different types of luminaires.
  • the individual components of the lamp are arranged within a box-shaped container 8, which is sunk when mounting the lamp in the ceiling of the room to be illuminated.
  • the light source used is a rod-type gas discharge lamp 1, under which a grid 6 consisting of side reflectors and transverse slats is arranged, via which a large part of the light emitted by the lamp 1 is emitted downwards.
  • the concrete shapes of this grid 6 can be chosen so that the downwardly radiated light is transversely dazzled to a certain extent, so that the lamp is particularly suitable for the illumination of rooms with VDU workstations.
  • a perforated plate which may be e.g. is deposited with foils, or another optical element - for example, a diffuser or a prismatic structure - are used.
  • the rod-shaped gas discharge lamp 1 is further spanned by a concave reflector 2 whose side wings are arranged substantially adjacent to the lamp 1.
  • a diffuser 3 is further arranged, which includes two light chambers 4 together with the reflector 2 by the diffuser 3 and the reflector 2 both converge at their remote from the lamp 1 end.
  • the light entry surfaces for these light chambers 4 are delimited by the upper edge of the grid 6 and the reflector 2. Since the diffuser 3 arranged in front of the reflector 2 extends up to the side wall of the grid 6, it is avoided that the lamp 1 can be viewed directly from the side, thus producing glare effects.
  • the width (a) of the light chambers 4 is according to the invention at least four times as large as the height (b) of the light entry surfaces, ie the distance between the upper edge of the grid 6 and the reflector 2, so that the lamp can be made very flat overall and visually appealing ,
  • the size ratio is between 4: 1 and 5: 1.
  • the two light entry surfaces are formed by diffusers 5, which distribute the light thrown onto the reflector 2 evenly. Together with the front of the reflector 2 arranged diffuser 3 is thus causes the lamp 1 and the grid 6 surrounding area of the lamp appears uniformly bright, despite the low height of the lamp.
  • the diffusers 5 are preferably formed integrally with the diffuser 3.
  • the reflector 2 may be diffusely reflecting on its inside.
  • the reflector 2 is further formed partially transparent, wherein behind this reflector 2 two further rod-shaped lamps 7 are arranged. These are for the achievement of the desired lighting effect - effective radiation of a large part of the light emitted by the lamp 1 on the grid 6 down and uniform brightening of the area surrounding the lamp 1 - initially not necessary, but with their help additional and new lighting effects can be met .
  • the two lights 7, for example, can be set independently of the light 1 to a certain brightness, so that in this way is given the opportunity to lighten the next to the lamp 1 arranged area regardless of the brightness of the lamp 1.
  • the luminaire shown in FIG. 2 is a recessed luminaire for a visible rail system.
  • the lamp is suspended in two laterally arranged by her and anchored in the ceiling rails 9.
  • this lamp is very similar to the recessed ceiling light shown in Fig. 1, but in this example, the reflector 2 is not teillicht trimeller.
  • the two light entry surfaces for the light chambers 4 are in turn formed by two diffusers 5, which, however, additionally have a light transparency which changes over the height of the diffuser 5.
  • the luminaire shown in FIG. 3 is likewise a recessed luminaire, which in this case is suspended in two suspended ceiling elements 10, which are arranged laterally of the luminaire.
  • the two light entry surfaces for the light chambers 4 are formed by a prism structure 11, which causes the light beams S 3 emitted by the lamp 1 to be directed, as they pass through this prism structure 11, to areas of the reflector 2 which are more remote from the lamp 1. This measure also serves to achieve a more uniform luminance over the reflector cross section.
  • the lamp shown in Fig. 4 is partially recessed in a suspended ceiling element 10, however, the turn-trained partially translucent reflector 2 is spaced from the bottom of this ceiling element 10. In contrast to the embodiment shown in FIG. 1, however, no further light sources are arranged behind the reflector 2.
  • the partial translucent reflector 2 is used in this example to additionally brighten a part of the light directed by the lamp 1 into the light chambers 4 also the area of the ceiling element 10 lying above the light, which results in a further visually appealing lighting effect.
  • FIGS. 5 and 6 are a ceiling-mounted luminaire (FIG. 5) and a pendant luminaire (FIG. 6) Structure of the lamp shown in Fig. 4 correspond.
  • the reflector 2 is formed such that more distant from the lamp 1 areas have a higher reflectivity than the lamp 1 near-lying areas.
  • a further measure could also consist in that areas of the diffuser 3 which are more remote from the lamp 1 have a higher light transmission than the areas lying near the lamp 1.
  • the luminaire shown in Fig. 7 is also designed as a surface-mounted luminaire, but now has a different reflector shape.
  • the reflector 2 is no longer integrally formed in contrast to the previous embodiments, but consists of two laterally to the ceiling extending concave curved Wings.
  • the ratio according to the invention between the width (a) of the light chambers 4 and the height (b) of the light entry surfaces is also fulfilled here.
  • the two side wings of the front of the reflector 2 arranged diffuser 3 extend to the ceiling, so that overall seen a continuous transition from the lamp to the ceiling is achieved.
  • light entry surfaces for the light chambers 4, which in turn are formed by two diffusers 5, are formed between the upper edge of the raster reflector 6 arranged below the lamp 1 and the reflector 2.
  • the reflector 2 is again formed partially transparent and there are two further lamps 7 are arranged to achieve further lighting effects above this reflector.
  • the luminaire shown in FIG. 7 is again designed as a recessed luminaire for a visible rail system or for a suspended ceiling system.
  • the two diffusers 5 are additionally provided with color filters, so that the light directed into the light chambers 4 has a different color composition than the light emitted downwards via the raster reflector 6.
  • This has the consequence that the area surrounding the lamp 1 appears in a slightly different color, so that certain moods can be generated by the choice of a suitable color filter.
  • a very pleasant atmosphere can be created by giving the light directed onto the reflector 2 a slightly warmer color tone with the aid of, for example, a light yellowish or orange colored color filter.
  • Fig. 10 shows a further embodiment in which the previously illustrated lamp is designed with the laterally upwardly extending side wings as a pendant, again the reflector 2 is formed partially transparent, to achieve a brightening of the ceiling area.
  • the luminaire shown in FIG. 11 again is a recessed ceiling luminaire, the reflector 2 of which, however, now has a shape such that the greatest distance (c) between the reflector 2 and the diffuser 3 is greater than the height (b) of FIG light entry surfaces.
  • the size ratio is preferably between 4: 1 and 5: 1.
  • FIGS. 12 and 13 show a further development of the luminaire according to the invention, which is particularly suitable for recessed ceiling luminaires, the shape of the luminaire shown in FIG. 12 being the luminaire shape in FIG. 11 and the shape of the luminaire in FIG. 13 being the luminaire shape of FIGS to 6 corresponds.
  • the development consists in that a further concave reflector 12 is arranged behind the part 2 permeable reflector 2, which forms together with the reflector 2, two further light chambers 13, which are each arranged behind the original light chambers 4.
  • additional light chambers 13 further light sources are arranged, here in the form of printed circuit boards with a plurality of LEDs 14 arranged in a row.
  • LED's 14 can be controllable with respect to their color and brightness, whereby a variety of different lighting effects can be achieved. Of course, other controllable light sources can be used.
  • the formation of the further light chambers 13 by the additional reflector 12 also in the other types of luminaires and luminaire shapes.
  • the lamp according to the invention can thus be configured in a variety of different manifestations; e.g. as built-in, surface-mounted luminaire and pendant luminaire, but also as floor lamp.
  • the different reflectors, diffusers, lamp arrangements, color filters, grids, perforated sheets and prism structures described above can be combined in any desired manner. Since the height of the light chambers 4 is very low, it is also possible to form a total of very flat and visually appealing lights and give them new shapes with an attractive design. The further proposed measures, however, can be achieved despite the very flat design, that over the entire width of the reflector 2, a substantially uniform luminance is achieved, so that very attractive lighting effects can be achieved.
