Abstract

The invention relates to a lamp comprising a tubular gas discharge lamp (1) provided with at least one concave reflector (2) which, when viewed from the area to be illuminated, is arranged next to the lamp (1), and provided with at least one at least partially transparent diffuser (3) which, also when viewed from the area to be illuminated, is arranged next to the lamp (1), however, in front of the reflector (2). The diffuser (3) and the reflector (2) delimit, next to the lamp (1), at least one light entry surface and converge at their end located at a distance from the lamp (1). They converge such that they form at least one light chamber (4), whereby the ratio between the width (a) of a light chamber and the height (b) of the light entry surface is equal to at least 4: 1. In addition, means can be provided in order to obtain a uniform luminance over the width of the reflector.

Description

  • Die vorliegende Erfindung betrifft eine Deckeinleuchte nach dem Oberbegriff des Anspruchs 1. The present invention relates to a Deckeinleuchte according to the preamble of claim 1.
  • Eine Deckeinleuchte dieser Art, wie sie beispielsweise in der DE 44 43 916 A1 beschrieben ist, ist in Fig. 5 dargestellt. A Deckeinleuchte of this type, as described for example in DE 44 43 916 A1 is shown in Fig. 5. Dabei ist unterhalb einer länglichen Gasentladungslampe 21 ein aus Seitenreflektoren und Querlamellen bestehender Rasterreflektor 26 angeordnet, mit dessen Hilfe der größte Teil des von der Lampe 21 abgegebenen Lichts gerichtet und blendfrei nach unten abgestrahlt wird. Here below an elongate gas discharge lamp 21, an existing of side reflectors and transverse lamellae grid reflector 26 is disposed, is directed by means of which most of the light emitted by the lamp 21 and glare-free downward. Die Verwendung eines derartigen Rasterreflektors 26 ist beispielsweise bei Leuchten in Büros mit mehreren Bildschirmarbeitsplätzen von Vorteil, da das nach unten abgestrahlte Licht bis zu einem gewissen Grad querentblendet ist und daher auf den Bildschirmen keine Reflexionen verursachen kann. The use of such a grid reflector 26 is, for example, in lighting in offices with several workstations advantageous because the radiated light is down to a certain degree of lateral glare and can therefore cause no reflections on the screens.
  • Die in Fig. 5 dargestellte Leuchte weist ferner einen konkav gekrümmten Außenreflektor 22 auf, auf den das von der Lampe 21 seitlich bzw. nach oben abgestrahlte Licht fällt. The luminaire shown in Fig. 5 further comprises a concavely curved outer reflector 22, to which the light emitted from the lamp 21 laterally or upward light falls. Auf diese Weise wird der die Lampe 21 und den Rasterreflektor 26 umgebende Bereich zusätzlich erhellt, was zum einen ermöglicht, auf einfache Weise zu erkennen, ob die Leuchte tatsächlich eingeschaltet ist oder nicht, andererseits aber auch von einem Betrachter als wesentlich angenehmer empfunden wird, als das Licht einer reinen Rasterleuchte, bei der das gesamte Licht lediglich nach unten abgestrahlt wird, so daß der Deckenbereich selbst dunkel erscheint. In this way, the lamp 21 and the grating reflector is additionally illuminated 26 surrounding area, which allows for one to easily detect whether the light is actually on or not, but on the other hand is also perceived by an observer as significantly more pleasant than the light of a pure grid light in which all light is emitted only downward, so that the ceiling area itself appears dark.
  • Bei derartigen Lampen ist es in der Regel erwünscht, daß der die Lampe umgebende Bereich in einer gleichmäßigen Helligkeitsdichte erscheint. In such lamps, it is usually desired that the region surrounding the lamp appears in a uniform brightness density. Dieses Problem wird beispielsweise auch in der DE 4 336 023 A1 behandelt. This problem is addressed, for example, in DE 4336023 A1. In der Regel weist daher der Außenreflektor einer derartigen Leuchte eine bestimmte und zuvor genau berechnete Krümmung auf, die das von der Lampe seitlich abgegebene Licht in einer derartigen Weise reflektiert, daß der Außenreflektor gleichmäßig hell erscheint. As a rule, therefore, the outer reflector of such a lamp in a certain and previously precisely calculated curvature that reflects the laterally emitted from the lamp in such a manner that the outer reflector appears uniformly bright. Dies hat allerdings dann meistens zur Folge, daß der Außenreflektor aufgrund dieser vorgegebenen Krümmung eine relativ große Höhe und geringe Breite aufweist, so daß die Leuchte insgesamt sehr hoch ist. This has, however, it is usually the consequence that the outer reflector due to this predetermined curvature has a relatively large height and small width, so that the light is very high as a whole. Würde hingegen der Außenreflektor 22 flacher gestaltet werden, so hätte dies zur Folge, daß die Leuchtdichte in der Lampe 21 naheliegenden Bereichen des Außenreflektors 22 höher ist als am Rand des Reflektors. Conversely, if the external reflector are designed 22 flat, then this would mean that the luminance in the lamp 21 proximate regions of the outer reflector 22 is higher than at the edge of the reflector. Bei der in Fig. 14 dargestellten Leuchte wird eine gleichmäßige Verteilung der Helligkeitsdichte zusätzlich dadurch unterstützt, daß unterhalb des . In the illustrated in Fig. 14 lamp a uniform distribution of brightness density is additionally supported by the fact that below the. Außenreflektors 22 eine durchscheinende (opale) Scheibe 23 angeordnet ist. is disposed outside the reflector 22 is a translucent (opal) disc 23rd Insgesamt weist jedoch auch diese Leuchte eine relativ große Höhe auf. Overall, however, also has this light on a relatively large height.
  • Es ist Aufgabe der vorliegenden Erfindung, eine Deckeneinbauleuchte 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 ceiling light, which has a significantly lower height than known luminaires and with regard to their shape provides more design options.
  • Diese Aufgabe wird durch eine Deckeneinbauleuchte, welche die Merkmale des Anspruchs 1 aufweist, gelöst. This object is achieved by a ceiling light, comprising the features of claim 1.
  • Die erfindungemäße Deckenleuchte hat mit der bekannten Leuchte nach Fig. 5 folgende gemeinsame Merkmale: eine rohrförmige Gasentladungslampe, mindestens einen - von dem zu beleuchtenden Bereich aus gesehen - neben der Lampe angeordneten konkav gekrümmten Reflektor, mindestens einen - ebenfalls von dem zu beleuchtenden Bereich aus gesehen - neben der Lampe aber vor dem Reflektor angeordneten zumindest teillichtdurchlässigen Diffusor sowie ein - von dem zu beleuchtenden Bereich aus gesehen - vor der Lampe angeordneten Lichtverteiler-Element, wobei der Diffusor und der Reflektor an ihrem von der Lampe entfernten Ende derart zusammenlaufen, dass sie mindestens eine Lichtkammer einschließen, und wobei der Reflektor nächst der Lampe mindestens eine Lichteintrittsfläche begrenzt. The erfindungemäße ceiling light has with the known lamp of FIG 5, the following common characteristics: a tubular gas discharge lamp, at least one - as seen from the region to be illuminated from - neighboring the lamp arranged concavely curved reflector, at least one - as seen also from the region to be illuminated from. - neighboring the lamp but before the reflector arranged at least partially light permeable diffusor and a - seen from the region to be illuminated from - arranged in front of the lamp light distributor element, the diffuser and the reflector at its end remote from the lamp end converge in such a way that it comprises at least include a light chamber, and wherein the reflector next to the lamp defining at least one light entry surface. Erfindungsgemäß wird die Lichteintrittsfläche außerdem von dem Diffusor begrenzt und das Verhältnis zwischen der Breite einer Lichtkammer und der Höhe der Lichteintrittsfläche beträgt mindestens 4:1, wobei unter der Höhe der Lichteintrittsfläche der in diesem Bereich vorliegende Abstand zwischen dem Reflektor und dem Diffusor verstanden wird. According to the invention the light entry surface is further bounded by the diffusor and the ratio between the width of a light chamber and the height of the light entry surface is at least 4: 1, being understood to mean the height of the light input surface of the present in this area the distance between the reflector and the diffuser. Ein weiteres Erfindungsmerkmal ist, dass die einzelnen Bauteile der Leuchte innerhalb eines kastenförmigen Gehäuses angeordnet sind. Another feature of the invention that the individual components of the luminaire are arranged within a box-shaped housing. Diese Maßnahmen haben zur Folge, dass die Leuchte insgesamt wesentlich flacher gestaltet werden kann und außerdem die Möglichkeit besteht, den Leuchten ein völlig neues Aussehen zu geben. These measures have the result that the lamp can be designed overall significantly flatter and it is also possible to give the lights a whole 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. In the event that the largest distance between the reflector and the diffusor is greater than the height of the light entry surface, preferably the ratio of the width of a light chamber to this greatest distance at least 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. 1 and 5: 1 More preferably, the ratio of the width of a light chamber to the height of the light entry surface or the largest distance between the reflector and the diffusor is between 4.
  • Eine nach der DE 297 10 475 U bekannte Deckenleuchte weist kein Gehäuse auf. A according to DE 297 10 475 U known ceiling lamp has no housing. Ein Lichteintritt in ebenfalls vorgesehene Lichtkammern erfolgt über Spalte im Rasterreflektor. A light entering also provided light chambers via column in the grid reflector.
  • Nach der US 5,530,628 ist eine Schrankleuchte bekannt, die Licht blendfrei schräg nach hinten abstrahlen soll. According to US 5,530,628 a luminaire is known cabinet, which is to glare emit light obliquely to the rear. Sie weist ebenfalls eine flache Lichtkammer auf, deren Lichteinstrahlfläche von einem Reflektor und einem Diffusor begrenzt ist. It also has a flat light chamber, the light irradiation is limited by a reflector and a diffuser.
  • Zum Erzielen einer gleichmäßigen Leuchtdichte über den Reflektorquerschnitt können mehrere zusätzliche Mittel an der Leuchte vorgesehen sein. To achieve a uniform light density over the reflector cross-section more additional means may be provided on the luminaire. Vorzugsweise werden zB die Lichteintrittsflächen für die Lichtkammer bzw. Lichtkammern ebenfalls durch Diffusoren gebildet. Preferably, for example, the light entry surfaces of the light chamber or the light chambers are also constituted by diffusers.
  • Das Lichtverteiter-Element kann zB ein aus Seitenreflektoren und Querlamellen bestehendes Raster sein. The Lichtverteiter element can be composed of side reflectors and cross louvre example. Auch andere optische Elemente wären denkbar, die ein interessanteres Aussehen der gesamten Leuchte bewirken, beispielsweise ein teillichtdurchlässiges Lochblech oder dergleichen. Other optical elements are conceivable, which bring about a more interesting appearance of the overall luminaire, for example a partially translucent perforated plate or the like.
  • Weiterbildungen der Leuchte können auch darin bestehen, daß der seitlich von der Lampe angeordnete Reflektor selbst teillichtdurchlässig ist. Further developments of the lamp can also consist in that the laterally disposed from the lamp reflector itself is partially light permeable. Es besteht dann die Möglichkeit, hinter diesem teillichtdurchlässigen Reflektor weitere Lichtquellen anzuordnen, die zum Erzielen besonderer Beleuchtungseffekte verwendet werden können. There is then the possibility of arranging additional light sources behind the partially light permeable reflector that 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. If the reflector is partially light permeable, so a different training may also be to arrange a further reflector behind the reflector, so that in each case one further light chamber is formed behind the light chambers. Es besteht dann die Möglichkeit, innerhalb dieser weiteren Lichtkammern zusätzliche Lichtquellen anzubringen, die beispielsweise in ihrer Farbe und Helligkeit steuerbar sein können. It is then possible to install additional light sources within these further light chambers, which can be controllable in their color and brightness, for example. Hierbei kann es sich beispielsweise um steuerbare lichtemittierende Dioden (LED's) handeln. This may, for example, controllable light-emitting diodes (LED's) act. Dadurch können nochmals eine Vielzahl unterschiedlicher Beleuchtungseffekte erzielt werden. Thus, a variety of lighting effects can be achieved again.
  • 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, may also be provided to obtain a further new lighting effect that optical elements are arranged within the light entry surfaces, which cause a change in color of the now on the reflector light, so that the region surrounding the lamp appears in a slightly different color.
  • Die erfindungsgemäße Leuchte kann dabei in mehreren verschiedenen Leuchtenarten Verwendung finden. The inventive light can thereby be found in several different types of luminaire used.
  • Im folgenden soll die Erfindung anhand der beiliegenden Zeichnung näher erläutert werden. In the following the invention with reference to the accompanying drawings is to be explained in more detail. Es zeigen: Show it:

    eine aus dem Stand der Technik bekannte Leuchte. a well-known from the prior art lamp.
  • Bei der in Fig. 1 dargestellten Deckeneinbauleuchte sind die einzelnen Bauteile der Leuchte innerhalb eines kastenförmigen Behälters 8 angeordnet, der beim Montieren der Leuchte in der Decke des zu beleuchtenden Raumes versenkt wird. In the illustrated in Fig. 1 downlight, the individual components of the luminaire are arranged within a box-shaped container 8, which is recessed in mounting the lamp in the ceiling of the room to be illuminated. Als Lichtquelle dient eine stabförmige Gasentladungslampe 1, unter der ein aus Seitenreflektoren und Querlamellen bestehendes Raster 6 angeordnet ist, über den ein Großteil des von der Lampe 1 abgegebenen Lichts nach unten abgestrahlt wird. a rod-shaped gas discharge lamp 1 under which a consisting of side reflectors and transverse lamellae louver 6 is arranged, via which a large part of the light emitted by the lamp 1 is radiated downward serves as a light source. Dabei können die konkreten Formen dieses Rasters 6 so gewählt werden, daß das nach unten abgestrahlte Licht bis zu einem gewissen Grad querentblendet wird, so daß die Leuchte insbesondere zur Beleuchtung von Räumen mit Bildschirmarbeitsplätzen geeignet ist. In this case, the concrete forms of this grid 6 can be chosen so that the emitted light is down to a certain degree of lateral glare, so that the lamp in particular for lighting rooms with workstations is suitable. Alternativ zu dem Rasters 6 kann auch ein Lochblech, welches zB mit Folien hinterlegt ist, oder ein anderes optisches Element - beispielsweise ein Diffusor oder eine Prismenswktur - verwendet werden. Alternatively to the grid 6 may also be a perforated plate, which for example is deposited with films, or other optical element - be used - for example a diffuser or a Prismenswktur.
  • Die stabförmige Gasentladungslampe 1 wird ferner von einem konkav gekrümmten Reflektor 2 überspannt, dessen Seitenflügel im wesentlichen neben der Lampe 1 angeordnet sind. The rod-shaped gas discharge lamp 1 is further covered by a concave reflector 2 whose side wings are arranged substantially next to the lamp. 1 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. Before this reflector 2, and thus also a diffuser 3 is laterally from the lamp 1 is further arranged, which includes two light chambers 4 together with the reflector 2 by the diffuser 3 and the reflector 2 together both run at its end remote from the lamp 1 end. Dabei werden die Lichteintrittsflärchen für diese Lichtkammern 4 von der Oberkante des Rasters 6 und dem Reflektor 2 begrenzt. The Lichteintrittsflärchen for these light chambers 4 from the upper edge of the grid 6 and the reflector 2 are limited. 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. Since the front of the reflector 2 arranged diffuser 3 extends up to the side wall of the grid 6, it is avoided that the lamp 1 can be viewed directly seen from the side and thereby caused glare.
  • 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. 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, so the distance between the upper edge of the grid 6 and the reflector 2, so that the lamp can be designed generally very flat and visually appealing , Vorzugsweise liegt das Größenverhältnis zwischen 4:1 und 5:1. Preferably, the size ratio is between 4: 1 and 5: 1.
  • Zum Erzielen einer gleichmäßigen Leuchtdichte über die gesamte Breite des Reflektors 2 ist bei der in Fig. 1 dargestellten Leuchte ferner vorgesehen, daß die beiden Lichteintrittsflächen durch Diffusoren 5 gebildet werden, die das auf den Reflektor 2 geworfene Licht gleichmäßiger verteilen. To achieve a uniform light density over the entire width of the reflector 2 in the illustrated in Fig. 1 lamp is further provided that the two light entry surfaces are formed by diffusers 5, which distribute the reflected on the reflector 2 light more evenly. Zusammen mit dem vor dem Reflektor 2 angeordneten Diffusor 3 wird somit bewirkt, daß der die Lampe 1 und das Raster 6 umgebende Bereich der Leuchte gleichmäBig hell erscheint, trotz der nur geringen Höhe der Leuchte. Together with the front of the reflector 2 arranged diffuser 3 is thus causes the lamp 1 and the screen 6 surrounds the region of the light gleichmäBig appears bright in spite of the only small amount of light. Dabei sind die Diffusoren 5 vorzugsweise zusammen mit dem Diffusor 3 einstückig ausgebildet. The diffusers 5 are preferably integrally formed together with the diffuser. 3 Ferner kann der Reflektor 2 an seiner Innenseite diffus reflektierend sein. Further, the reflector 2 may be diffusely reflective on its inner side.
  • Im dargestellten Beispiel ist der Reflektor 2 ferner teillichtdurchlässig ausgebildet, wobei hinter diesem Reflektor 2 zwei weitere stabförmige Lampen 7 angeordnet sind. In the illustrated example, the reflector 2 is further formed partially light permeable, with 2 two rod-shaped lamps 7 are arranged behind the reflector. 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. These are to achieve the desired lighting effect - effective radiation of a large part of light emitted from the lamp 1 light over the screen 6 to bottom, as well as uniform illumination of the lamp 1 surrounding area - initially not necessary, however, additional and new lighting effects can be met with its help , 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. The two lamps 7 can be adjusted independently of the lamp 1 to a given brightness, for instance, so that in this way the possibility is given to lighten the lamp 1 arranged next to the area regardless of the brightness of the lamp. 1
  • Bei der in Fig. 2 dargestellten Leuchte handelt es sich wiederum um eine Deckeneinbauleuchte, deren Reflektor 2 nun allerdings eine derartige Form aufweist, daß der größte Abstand (c) zwischen dem Reflektor 2 und dem Diffusor 3 größer ist als die Höhe (b) der Lichteintrittsflächen. In the illustrated in Fig. 2 light is again a ceiling light, the reflector 2 is now, however, has such a shape that the greatest spacing (c) between the reflector 2 and the diffuser 3 is greater than the height (b) of the light entry surfaces. In diesem Fall beträgt vorzugsweise nicht nur das Verhältnis zwischen der Breite (a) der Lichtkammern 4 zur Höhe (b) der Lichteintrittsflächen sondern sogar das Verhältnis der Breite (a) der Lichtkammern 4 zu diesem größten Abstand (c) mindestens 4:1, so daß eine flache Bauform sichergestellt ist. In this case, not only the relationship between the width (a) is preferably the light chambers 4 to the height (b) of the light entry surfaces but also the ratio of the width (a) of the light chambers 4 of this greatest distance (c) at least 4: 1, so that a compact design is ensured. Wiederum liegt das Größenverhältnis vorzugsweise zwischen 4:1 und 5:1. Again, the size ratio is preferably between 4: 1 and 5: 1.
  • Die Figuren 3 und 4 zeigen schließlich eine Weiterbildung der erfindungsgemäßen Leuchte, die sich insbesondere bei Deckeneinbauleuchten anbietet, wobei die Form der in Fig. 3 dargestellten Leuchte der Leuchtenform in Fig. 2 und die Form der Leuchte in Fig. 4 der Leuchtenform der Figur 1 entspricht. Figures 3 and 4, finally, show a further embodiment of the lamp according to the invention lends itself in particular in Ceiling recessed lighting, wherein the shape of the lamp of the luminaire shape in Fig illustrated in FIG. 3. 2, and the form of the lamp in Fig. 4 of the luminaires form the figure 1 equivalent. Die Weiterbildung besteht darin, daß hinter dem teillichtdurchlässig ausgestalteten Reflektor 2 eine weiterer konkaver Reflektor 12 angeordnet ist, der zusammen mit dem Reflektor 2 zwei weitere Lichtkammern 13 bildet, die jeweils hinter den ursprünglichen Lichtkammern 4 angeordnet sind. The development consists in that a further concave reflector 12 is arranged behind the partially light permeable reflector configured 2 which forms together with the reflector 2 two more light chambers 13 which are disposed respectively behind the original light chambers. 4 In diesen zusätzlichen Lichtkammern 13 sind weitere Lichtquellen angeordnet, hier in Form von Leiterplatinen mit mehreren in einer Reihe angeordneten LED's 14. Diese LED's 14 können bezüglich ihrer Farbe und Helligkeit steuerbar sein, wodurch eine Vielzahl unterschiedlicher Lichteffekte erzielt werden können. In these additional light chambers 13 more light sources are arranged, here in the form of printed circuit boards with several arranged in a series of LED's 14. The LED's 14 may be controlled with respect to their color and brightness, whereby a plurality of different light effects can be achieved. Selbstverständlich können auch andere steuerbare Lichtquellen zum Einsatz kommen. Of course, other controllable light sources can be used. Darüber hinaus kann die Bildung der weiteren Lichtkammern 13 durch den zusätzlichen Reflektor 12 auch bei den anderen Leuchtentypen und Leuchtenformen erfolgen. Moreover, the formation of the further light chambers 13 through the additional reflector 12 in the other types of luminaires and luminaire designs can take place.
  • Die erfindungsgemäße Leuchte kann somit in einer Vielzahl von unterschiedlichen Erscheinungsformen ausgestaltet sein. The lamp of the invention can thus be designed in a variety of different forms. 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. Since the height of the light chambers 4 is very low, there is also the possibility of forming very flat and visually appealing overall lighting and to give them new forms with a sophisticated design. 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. By the further proposed measures, however, can be achieved despite the very flat design, that a substantially uniform luminance is obtained over the entire width of the reflector 2, so that even very appealing lighting effects can be achieved.
