Description

Die vorliegende Erfindung betrifft eine Deckeinleuchte nach dem Oberbegriff des Anspruchs 1.The present invention relates to a deck light 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. 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. 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.A Deckeinleuchte this kind, as described for example in DE 44 43 916 A1, is shown in Fig. 5. In this case, below an elongated gas discharge lamp 21, 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.

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. 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.The lamp shown in Fig. 5 further comprises a concave curved outer reflector 22, on which the light emitted from the lamp 21 laterally or upwards falls. In this way, 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.

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 DE 4 336 023 A1 behandelt. 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. 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. 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. Bei der in Fig. 14 dargestellten Leuchte wird eine gleichmäßige Verteilung der Helligkeitsdichte zusätzlich dadurch unterstützt, daß unterhalb des . Außenreflektors 22 eine durchscheinende (opale) Scheibe 23 angeordnet ist. Insgesamt weist jedoch auch diese Leuchte eine relativ große Höhe auf.In such lamps, it is usually desirable that the area surrounding the lamp appear in a uniform brightness density. This problem is also treated, for example, in DE 4 336 023 A1. In general, therefore, 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. However, this usually has the consequence that the outer reflector due to this predetermined curvature has a relatively high height and small width, so that the lamp is very high overall. If, on the other hand, 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. In the luminaire shown in FIG. 14, 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.

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 much lower height than the known lights and offers more design options in terms of their shape.

Diese Aufgabe wird durch eine Deckeneinbauleuchte, welche die Merkmale des Anspruchs 1 aufweist, gelöst.This object is achieved by a recessed ceiling luminaire, which has 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. 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. Ein weiteres Erfindungsmerkmal ist, dass die einzelnen Bauteile der Leuchte innerhalb eines kastenförmigen Gehäuses angeordnet sind. 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.The erfindungemäße ceiling light has the following common features with the known lamp according to Fig. 5: 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 - In addition to the lamp but in front of the reflector arranged at least partially translucent diffuser and - seen from the area to be illuminated - arranged in front of the lamp light distribution element, wherein the diffuser and the reflector at their end remote from the lamp converge so that they at least include a light chamber, and wherein the reflector next to the lamp limits at least one light entry surface. According to the invention, the light entry surface is also delimited by the diffuser and 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 be the distance between the reflector and the diffuser present in this region. Another feature of the invention is that the individual components of the lamp are arranged within a box-shaped housing. As a result of these measures, the luminaire as a whole can be made substantially flatter and, in addition, it is possible to give the luminaires a completely new appearance.

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.

Eine nach der DE 297 10 475 U bekannte Deckenleuchte weist kein Gehäuse auf. Ein Lichteintritt in ebenfalls vorgesehene Lichtkammern erfolgt über Spalte im Rasterreflektor.A according to 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.

Nach der US 5,530,628 ist eine Schrankleuchte bekannt, die Licht blendfrei schräg nach hinten abstrahlen soll. Sie weist ebenfalls eine flache Lichtkammer auf, deren Lichteinstrahlfläche von einem Reflektor und einem Diffusor begrenzt ist.After the US 5,530,628 a cabinet lamp is known to emit light glare-free at an angle to the rear. It also has a flat light chamber whose Lichteinstrahlfläche is bounded by a reflector and a diffuser.

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 Lichtverteiter-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-transmitting 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 can also be provided that within the light entry surfaces optical elements are arranged, which cause a change in color of the light has become on the reflector, so that the area surrounding the lamp appears in a slightly different color.

Die erfindungsgemäße Leuchte kann dabei in mehreren verschiedenen Leuchtenarten Verwendung finden.The luminaire according to the invention can be used in several different types of luminaires.

Im folgenden soll die Erfindung anhand der beiliegenden Zeichnung näher erläutert werden. Es zeigen:

In the following the invention will be explained in more detail with reference to the accompanying drawings. Show it:

a first embodiment of a ceiling luminaire according to the invention;
Fig. 2-4
Further embodiments of the ceiling recessed luminaire according to the invention; and
Fig. 5
a 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. 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. 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. Alternativ zu dem Rasters 6 kann auch ein Lochblech, welches z.B. mit Folien hinterlegt ist, oder ein anderes optisches Element - beispielsweise ein Diffusor oder eine Prismenswktur - verwendet werden.In the ceiling luminaire shown in Fig. 1, 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. As an alternative to the grid 6, 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.

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 Lichteintrittsflärchen 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 gas discharge lamp 1 is further spanned by a concave reflector 2 whose side wings are arranged substantially adjacent to the lamp 1. In front of this reflector 2 and thus also laterally of 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 Lichteintrittsflärchen for these light chambers 4 are limited 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.

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 grid 6 and the reflector 2, so that the light overall very flat and visually can be designed attractively. 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. 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. Dabei sind die Diffusoren 5 vorzugsweise zusammen mit dem Diffusor 3 einstückig ausgebildet. Ferner kann der Reflektor 2 an seiner Innenseite diffus reflektierend sein.To achieve a uniform luminance over the entire width of the reflector 2 is further provided in the light shown in Fig. 1 that 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 evenly bright, despite the low height of the lamp. In this case, the diffusers 5 are preferably formed integrally with the diffuser 3. Furthermore, the reflector 2 may be diffusely reflecting on its inside.

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 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.

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 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. Wiederum liegt das Größenverhältnis vorzugsweise zwischen 4:1 und 5:1.The luminaire shown in FIG. 2 again is a recessed ceiling luminaire whose reflector 2 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. In this case, preferably not only the ratio between the width (a) of the light chambers 4 to the height (b) of the light entrance surfaces but even 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. 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. 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. 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. Selbstverständlich können auch andere steuerbare Lichtquellen zum Einsatz kommen. Darüber hinaus kann die Bildung der weiteren Lichtkammern 13 durch den zusätzlichen Reflektor 12 auch bei den anderen Leuchtentypen und Leuchtenformen erfolgen.Finally, FIGS. 3 and 4 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. 3 being the luminaire shape in FIG. 2 and the shape of the luminaire in FIG. 4 being the luminaire shape of FIG 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. In these 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. In addition, the formation of the further light chambers 13 by the additional reflector 12 also in the other types of luminaires and luminaire shapes.

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. 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.
