Definitions
- the present invention relates to a ceiling lamp according to the preamble of claim 1.
- a ceiling lamp of this kind as for example in the DE 44 43 916 A1 is described in is Fig. 3 shown.
- 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.
- Fig. 3 also has a concave outer reflector 22, on which the light emitted from the lamp 21 laterally or upwards 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 outer reflector of such a luminaire on a certain and previously calculated precisely curvature, which reflects the light emitted by the lamp side in such a manner that the outer reflector appears uniformly bright.
- this usually has the consequence that the outer reflector has a relatively high height and small width due to this predetermined curvature, so that the lamp is very high overall.
- the outer reflector 22 were made flatter, this would mean that the luminance in the lamp 21 nearer to the outer reflector 22 is higher than at the edge of the reflector.
- a uniform distribution of the brightness density is additionally supported by the fact that below the outer reflector 22, a translucent (opal) disc 23 is arranged. Overall, however, this luminaire has a relatively high height.
- the ceiling lamp according to the invention has with the known lamp after Fig. 3 the following common features: a tubular gas discharge lamp, at least one - viewed from the area to be illuminated - arranged next to the lamp concave reflector, at least one - also seen from the area to be illuminated - next to the lamp but in front of the reflector arranged at least partially translucent diffuser and a light distribution element arranged in front of the lamp, viewed from the area to be illuminated, the diffuser and the reflector converging at their end remote from the lamp so as to enclose at least one light chamber, and the reflector closest to the lamp at least limited a light entrance surface.
- the light entry surface is delimited by the diffuser, and the largest distance between the reflector and the diffuser is greater than the height of the light entry surface, and the ratio of the width of a light chamber to the largest distance between the reflector and the diffuser 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 greatest distance between the reflector and the diffuser is between 4: 1 and 5: 1.
- One after the DE 297 10 475 U known ceiling lamp has no housing.
- a light entry into also provided light chambers via column in the raster reflector.
- US 5,530,628 is a cabinet lamp known to emit light glare-free at an angle to the rear. It also has a flat light chamber whose Lichteinstrahl requirements is bounded by a reflector and a diffuser.
- the light entry surfaces for the light chamber or light chambers are also formed by diffusers.
- the light distribution element may be, e.g. a grid consisting of side reflectors and cross blades.
- Other optical elements would be conceivable, which cause a more interesting appearance of the entire lamp, such as a teillichtyer 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.
- 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. It is then possible to install 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). This can be achieved again a variety of different lighting effects.
- LEDs controllable light-emitting diodes
- optical elements are arranged within the light entry surfaces, which effect a color change of the light which has become on the reflector, so that the area surrounding the lamp appears in a slightly different color.
- the luminaire according to the invention can be used in several different types of luminaires.
- FIG. 1 Ceiling downlight shown, the individual components of the lamp within a box-shaped container 8 are arranged, 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.
- the grid 6 it is also possible to use a perforated plate, which is deposited, for example, with foils, or another optical element-for example a diffuser or a prismatic structure.
- 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 light overall very flat and visually can be designed attractively.
- 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 has a shape such that the largest distance (c) between the reflector 2 and the diffuser 3 is greater than the height (b) of the light entry surfaces.
- the ratio between the width (a) of the light chambers 4 to the height (b) of the light entry surfaces and the ratio of the width (a) of the light chambers 4 to this largest distance (c) is at least 4: 1, so that a flat design is ensured.
- FIG. 2 shows a development of the lamp according to the invention, which is particularly suitable for recessed ceiling lights, the shape of the in Fig. 2 illustrated luminaire of the luminaire form in Fig. 1 equivalent.
- 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.
- These 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 luminaire according to the invention can thus be configured in a multiplicity of different forms of appearance. 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.

Es ist Aufgabe der vorliegenden Erfindung, eine Leuchte anzugeben, die eine deutlich geringere Höhe als die bekannten Leuchten aufweist und hinsichtlich ihrer Form mehr Gestaltungsmöglichkeiten bietet.It is an object of the present invention to provide a lamp that has a significantly lower height than the known lights and offers more design options in terms of their shape.
Diese Aufgabe wird durch eine Leuchte, welche die Merkmale des Anspruches 1 aufweist, gelöst.This object is achieved by a luminaire having the features of
Die erfindungsgemäße Deckenleuchte hat mit der bekannten Leuchte nach
Gemäß einer bevorzugten Ausführungsform liegt das Verhältnis der Breite einer Lichtkammer zur Höhe der Lichteintrittsfläche bzw. zum größten Abstand zwischen dem Reflektor und dem Diffusor zwischen 4:1 und 5:1.According to a preferred embodiment, the ratio of the width of a light chamber to the height of the light entry surface or to the greatest distance between the reflector and the diffuser is between 4: 1 and 5: 1.

Zum Erzielen einer gleichmäßigen Leuchtdichte über den Reflektorquerschnitt können mehrere zusätzliche Mittel an der Leuchte vorgesehen sein. Vorzugsweise werden z.B. die Lichteintrittsflächen für die Lichtkammer bzw. Lichtkammern ebenfalls durch Diffusoren gebildet.To achieve a uniform luminance over the reflector cross section several additional means may be provided on the lamp. Preferably, for example, the light entry surfaces for the light chamber or light chambers are also formed by diffusers.
Das Lichtverteiler-Element kann, z.B. ein aus Seitenreflektoren und Querlamellen bestehendes Raster sein. Auch andere optische Elemente wären denkbar, die ein interessanteres Aussehen der gesamten Leuchte bewirken, beispielsweise ein teillichtdurchlässiges Lochblech oder dergleichen.The light distribution element may be, e.g. a grid consisting of side reflectors and cross blades. Other optical elements would be conceivable, which cause a more interesting appearance of the entire lamp, such as a teillichtdurchlässiges perforated plate or the like.
Weiterbildungen der Leuchte können auch darin bestehen, daß der seitlich von der Lampe angeordnete Reflektor selbst teillichtdurchlässig ist. Es besteht dann die Möglichkeit, hinter diesem teillichtdurchlässigen Reflektor weitere Lichtquellen anzuordnen, die zum Erzielen besonderer Beleuchtungseffekte verwendet werden können.Further developments of 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.
Ist der Reflektor teillichtdurchlässig, so kann eine andere Weiterbildung auch darin bestehen, hinter dem Reflektor einen weiteren Reflektor anzuordnen, so daß hinter den Lichtkammern jeweils eine weitere Lichtkammer gebildet wird. Es besteht dann die Möglichkeit, innerhalb dieser weiteren Lichtkammern zusätzliche Lichtquellen anzubringen, die beispielsweise in ihrer Farbe und Helligkeit steuerbar sein können. Hierbei kann es sich beispielsweise um steuerbare lichtemittierende Dioden (LED's) handeln. Dadurch können nochmals eine Vielzahl unterschiedlicher Beleuchtungseffekte erzielt werden.If 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. It is then possible to install 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). This can be achieved again a variety of different lighting effects.
Schließlich kann zum Erzielen eines weiteren neuen Beleuchtungseffekts auch vorgesehen sein, daß innerhalb der Lichteintrittsflächen optische Elemente angeordnet sind, die eine farbliche Veränderung des auf den Reflektor gewordenen Lichts bewirken, so daß der die Lampe umgebende Bereich in einer etwas anderen Farbe erscheint.Finally, to achieve a further new lighting effect, it may also be provided that optical elements are arranged within the light entry surfaces, which effect a color change of the light which has become on the reflector, so that the area surrounding the lamp appears in a slightly different color.

Bei der in
Die stabförmige Gasentladungslampe 1 wird ferner von einem konkav gekrümmten Reflektor 2 überspannt, dessen Seitenflügel im wesentlichen neben der Lampe 1 angeordnet sind. Vor diesem Reflektor 2 und somit ebenfalls seitlich von der Lampe 1 ist ferner ein Diffusor 3 angeordnet, der gemeinsam mit dem Reflektor 2 zwei Lichtkammern 4 einschließt, indem der Diffusor 3 und der Reflektor 2 beide an ihrem von der Lampe 1 entfernten Ende zusammenlaufen. Dabei werden die Lichteintrittsflächen für diese Lichtkammern 4 von der Oberkante des Rasters 6 und dem Reflektor 2 begrenzt. Da der vor dem Reflektor 2 angeordnete Diffusor 3 sich bis zu der Seitenwand des Rasters 6 erstreckt, wird vermieden, daß die Lampe 1 seitlich gesehen direkt betrachtet werden kann und somit Blendeffekte entstehen.The rod-shaped
Die Breite (a) der Lichtkammern 4 ist erfindungsgemäß mindestens viermal so groß wie die Höhe (b) der Lichteintrittsflächen, also dem Abstand zwischen der Oberkante des Rasters 6 und dem Reflektor 2, so daß die Leuchte insgesamt sehr flach und optisch ansprechend gestaltet werden kann. Vorzugsweise liegt das Größenverhältnis zwischen 4:1 und 5:1.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

Die erfindungsgemäße Leuchte kann somit in einer Vielzahl von unterschiedlichen Erscheinungsformen ausgestaltet sein. Da die Höhe der Lichtkammern 4 sehr gering ist, besteht ferner die Möglichkeit, insgesamt sehr flache und optisch ansprechende Leuchten zu bilden und ihnen neue Formen mit einem ansprechenden Design zu geben. Durch die weiteren vorgeschlagenen Maßnahmen kann allerdings trotz der sehr flachen Bauform erreicht werden, daß über die gesamte Breite des Reflektors 2 eine im wesentlichen gleichmäßige Leuchtdichte erzielt wird, so daß auch sehr ansprechende Beleuchtungseffekte erzielt werden können.The luminaire according to the invention can thus be configured in a multiplicity of different forms of appearance. 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.
