Definitions
- the present invention relates to a luminaire according to the preamble of claim 1.
- a lamp of this kind as for example in the DE 44 43 916 A1 is described in is Fig. 14 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. 14 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 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.
- 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 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 lightening 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 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 light is the in Fig. 1
- 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 light shown is also a recessed luminaire, which is suspended in this case in two suspended ceiling elements 10, which are arranged laterally of the lamp.
- the two light entry surfaces for the Lichtkammem 4 are formed by a prism structure 11, which causes the output from the lamp 1 light beams S3 are directed on passing through this prism structure 11 on the lamp 1 more remote areas of the reflector 2. This measure also serves to achieve a more uniform luminance over the reflector cross section.
- the turn-trained partially transparent reflector 2 is spaced from the underside of this ceiling element 10. Unlike the in Fig. 1 illustrated embodiment, however, no further light sources are now 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 above the light, resulting in a further visually appealing lighting effect.
- FIGS. 5 and 6 An additional brightening of the lying above the lamp ceiling area is also in the in the FIGS. 5 and 6 achieved embodiments shown, which is a ceiling mounted luminaire ( Fig. 5 ) and a pendant lamp ( Fig. 6 ), which in its further construction of the Fig. 4 match the light shown.
- 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.
- Fig. 7 illustrated light is also designed as a ceiling 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 in Fig. 7 shown lamp 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 with the laterally extending side wings is designed as a pendant light, again the reflector 2 is formed partially permeable to achieve a brightening of the ceiling area.
- the reflector 2 now 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 size ratio is preferably between 4: 1 and 5: 1.
- FIGS. 12 and 13 show a development of the lamp according to the invention, which is particularly suitable for recessed ceiling lights, the shape of the in Fig. 12 illustrated luminaire of the luminaire form in Fig. 11 and the shape of the light in Fig. 13 the luminaire shape of the FIGS. 1 to 6 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.
- 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.

Abstract
Description
Die vorliegende Erfindung betrifft eine Leuchte nach dem Oberbegriff des Anspruchs 1.The present invention relates to a luminaire according to the preamble of
Eine Leuchte dieser Art, wie sie beispielsweise in der
Die in
Bei derartigen Lampen ist es in der Regel erwünscht, daß der die Lampe umgebende Bereich in einer gleichmäßigen Helligkeitsdichte erscheint. Dieses Problem wird beispielsweise auch in der
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 Leuchte weist eine rohrförmige Gasentladunglampe auf, mindestens einen - von dem zu beleuchtenden Bereich aus gesehen - neben der Lampe angeordneten konkav gekrümmten Reflektor sowie mindestens einen - ebenfalls von dem zu beleuchtenden Bereich aus gesehen - neben der Lampe aber vor dem Reflektor angeordneten zumindest teillichtdurchlässigen Diffusor. Der Diffusor und der Reflektor begrenzen nächst der Lampe mindestens eine Lichteintrittsfläche und laufen an ihrem von der Lampe entfernten Ende derart zusammen, daß sie mindestens eine Lichtkammer einschließen. Erfindungsgemäß beträgt das Verhältnis zwischen der Breite einer Lichtkammer und der Höhe der Lichteintrittsfläche mindestens 4:1, wobei unter der Höhe der Lichteintrittsfläche der in diesem Bereich vorliegende Abstand zwischen dem Reflektor und dem Diffusor verstanden wird. Diese Maßnahme hat zur Folge, daß die Leuchte insgesamt wesentlich flacher gestaltet werden kann und außerdem die Möglichkeit besteht, den Leuchten ein völlig neues Aussehen zu geben.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. According to the invention, 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.
Für den Fall, daß der größte Abstand zwischen dem Reflektor und dem Diffusor größer als die Höhe der Lichteintrittsfläche ist, beträgt vorzugsweise das Verhältnis der Breite einer Lichtkammer zu diesem größten Abstand mindestens 4:1. Besonders bevorzugt 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.In the event that the largest distance between the reflector and the diffuser is greater than the height of the light entry surface, preferably the ratio of the width of a light chamber to this largest distance is at least 4: 1. Particularly preferably, 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.
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. Eine andere Möglichkeit besteht darin, daß die Lichteintrittsflächen derart ausgebildet sind, daß ein höherer Anteil des von der Lampe in eine Lichtkammer abgegebenen Lichts auf entfernter liegende Bereiche des Reflektors gelenkt wird. Zu diesem Zweck können beispielsweise die zuvor erwähnten und die Lichteintrittsflächen bildenden Diffusoren eine unterschiedliche Lichtdurchlässigkeit aufweisen, oder es besteht die Möglichkeit, in den Lichteintrittsflächen optische Elemente - beispielsweise Prismenstrukturen oder dergleichen - anzubringen, welche das Licht in der gewünschten Weise auf den Reflektor lenken. Vorzugsweise ist die Oberfläche des Reflektors ebenfalls diffus reflektierend, sie kann aber auch derart ausgestaltet sein, daß von der Lampe entfernter liegende Bereiche einen höheren Reflexionsgrad aufweisen als der Lampe naheliegende Bereiche, was ebenfalls eine Vergleichmäßigung der Leuchtdichte unterstützt. Eine weitere Maßnahme kann darin bestehen, daß auch der vor dem Reflektor angeordnete Diffusor eine von der Entfernung zu der Lampe abhängige Lichtdurchlässigkeit aufweist.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. Another possibility is that 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. For this purpose, for example, 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. Preferably, 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.
Um das von der Lampe nach unten abgestrahlte Licht für eine effektive Beleuchtung verwenden zu können, kann unterhalb der Lampe ein Lichtverteiler-Element, z.B. ein aus Seitenreflektoren und Querlamellen bestehendes Raster angeordnet sein. Auch andere optische Elemente wären denkbar, die ein interessanteres Aussehen der gesamten Leuchte bewirken, beispielsweise ein teillichtdurchlässiges Lochblech oder dergleichen.In order to use the light radiated downwards by the lamp for effective illumination, 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 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. Andererseits kann in diesem Fall auch ein oberhalb der Leuchte liegender Deckenbereich aufgehellt werden.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. On the other hand, in this case, a lying above the light ceiling area can be brightened.
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. Die Bildung dieser zusätzlichen Lichtkammer bzw. Lichtkammern kann allerdings auch unabhängig von dem oben abgegebenen Größenverhältnis für eine Lichtkammer erfolgen und ist Gegenstand des Anspruchs 18.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. However, 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.
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, in order to achieve a further new lighting effect it can also be provided that 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.

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

Im dargestellten Beispiel ist der Reflektor 2 ferner teillichtdurchlässig ausgebildet, wobei hinter diesem Reflektor 2 zwei weitere stabförmige Lampen 7 angeordnet sind. Diese sind zum Erzielen des gewünschten Beleuchtungseffekts - effektive Abstrahlung eines Großteils des von der Lampe 1 abgegebenen Lichts über das Raster 6 nach unten sowie gleichmäßige Aufhellung des die Lampe 1 umgebenden Bereiches - zunächst nicht notwendig, allerdings können mit ihrer Hilfe zusätzliche und neue Beleuchtungseffekte erfüllt werden. Die beiden Leuchten 7 können beispielsweise unabhängig von der Leuchte 1 auf eine bestimmte Helligkeit eingestellt werden, so daß hierdurch die Möglichkeit gegeben ist, den neben der Lampe 1 angeordneten Bereich unabhängig von der Helligkeit der Lampe 1 aufzuhellen.In the example shown, the

Auch die beiden Seitenflügel des vor dem Reflektor 2 angeordneten Diffusors 3 erstrecken sich bis zur Decke, so daß insgesamt gesehen ein kontinuierlicher Übergang von der Leuchte zu der Decke erzielt wird. Auch hier werden zwischen der Oberkante des unter der Lampe 1 angeordneten Rasterreflektors 6 und dem Reflektor 2 Lichteintrittsflächen für die Lichtkammern 4 gebildet, die wiederum durch zwei Diffusoren 5 gebildet werden. Wie im ersten Ausführungsbeispiel ist der Reflektor 2 wiederum teillichtdurchlässig ausgebildet und es sind zum Erzielen weiterer Beleuchtungseffekte oberhalb dieses Reflektors 2 zwei weitere Lampen 7 angeordnet.The two side wings of the front of the

Die erfindungsgemäße Leuchte kann somit in einer Vielzahl von unterschiedlichen Erscheinungsformen ausgestaltet sein; z.B. als Einbau-, Anbauleuchte und Pendelleuchte, aber auch als Stehleuchte. Im Rahmen dieser Ausführungsformen können die zuvor beschriebenen unterschiedlichen Reflektoren, Diffusoren, Lampen- bzw. Leuchtmittelanordnungen, Farbfilter, Raster, Lochbleche und Prismenstrukturen in beliebiger Weise kombiniert werden. 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 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. In the context of these embodiments, the different reflectors, diffusers, lamp arrangements, color filters, grids, perforated sheets and prism structures described above can be combined in any desired manner.
