Abstract

An optical system (5,6) is located in the lamp chamber (3) above the lamp shade (2). Light radiates into the shade through an entry opening (2a) at its top. At the low edge of the lamp shade, there is an inwardly-projecting, diffusely-reflective flange (9). This reflects some of the light leaving, back into the lamp shade.

Description

Die vorliegende Erfindung betrifft eine Innenleuchte, insbesondere zur Beleuchtung von Warenpräsentationsflächen, mit einem transparenten Leuchtenschirm und einem optischen System mit einem Leuchtmittel.The present invention relates to an interior lamp, especially for lighting goods presentation areas, with a transparent lampshade and a optical system with a lamp.

Warenpräsentationsflächen wie beispielsweise Kühltheken, Obstschütten, Verkaufsregale etc. werden in der Regel künstlich beleuchtet. Ziel ist es dabei, die Oberflächen möglichst gleichmäßig auszuleuchten. Zu diesem Zweck werden beispielsweise Innenleuchten der eingangs genannten Art mit transparenten Leuchtenschirmen eingesetzt. Diese herkömmlichen Innenleuchten haben den Nachteil, daß von ihnen eine Blendwirkung ausgeht, da das Leuchtmittel von außen als besonders helle Stelle oder Fläche sichtbar ist. Des weiteren besitzen die Innenleuchten nur eine geringe Lichtlenkung mit der Folge, daß lediglich ein kleiner Teil des Lampenlichtstroms tatsächlich die zu beleuchtende Nutzfläche trifft. Des weiteren werden in solchen Innenleuchten häufig stehende Leuchtmittel und rotatiossymmetrische Reflektoren eingesetzt, die jeweils eine kreisrunde leuchtende Fläche erzeugen. Dies bringt den Nachteil mit sich, daß in der Kreismitte hohe Spitzenbeleuchtungsstärken erzielt werden mit der Folge, daß die Waren verblassen und ausbleichen können, und außerdem bei breiten Lichtverteilungen ein großer Teil des kreisrunden Lichtkegels nicht auf die Verkaufsmöbel, sondern in den Kunden- und Bedienungsraum fällt. Im Ergebnis ergibt sich ein schlechter Nutzbeleuchtungswirkungsgrad.Goods presentation areas such as refrigerated counters, Fruit chests, shelves etc. are usually artificially lit. The aim is to create the surfaces Illuminate as evenly as possible. For this purpose for example interior lights of the aforementioned Type used with transparent lampshades. This conventional interior lights have the disadvantage that they run out of glare because the illuminant from visible on the outside as a particularly bright spot or surface is. Furthermore, the interior lights have only a small one Light control with the result that only a small one Part of the lamp luminous flux actually is the one to be illuminated Usable space meets. Furthermore, in such Interior lights frequently standing lamps and rotationally symmetrical Reflectors used, each one create a circular, luminous surface. This brings the The disadvantage is that high peak illuminance levels in the center of the circle can be achieved with the result that the Goods can fade and fade, and also at wide light distributions a large part of the circular Cone of light not on the sales furniture, but in the Customer and service room falls. The result is poor useful lighting efficiency.

Alternativ werden deshalb auch Leuchten mit einem liegenden Leuchtmittel eingesetzt, die ovale leuchtende Flächen erzeugen. Zur Beleuchtung von länglichen Präsentationsflächen stellen diese Leuchten mit einem liegenden Leuchtmittel zwar eine Verbesserung dar, jedoch wird der Leuchtenschirm nach wie vor ungleichmäßig ausgeleuchtet.As an alternative, luminaires with a horizontal are therefore also used Illuminants used, the oval luminous surfaces produce. For lighting elongated presentation areas put these lights with a lying Illuminants are an improvement, but the Luminaire shade still illuminated unevenly.

Aufgabe der Erfindung ist es daher, eine Innenleuchte der eingangs genannten Art so auszubilden, daß der Leuchtenschirm gleichmäßig ausgeleuchtet wird und insbesondere Blendwirkungen vermieden werden.The object of the invention is therefore to provide an interior light type mentioned so that the lampshade is evenly illuminated and in particular Glare can be avoided.

Diese Aufgabe ist erfindungsgemäß dadurch gelöst, daß das optische System in einem oberhalb des Leuchtenschirms vorgesehenen Leuchtmittelraum positioniert ist und durch eine Lichteintrittsöffnung an der Oberseite des Leuchtenschirms in diesen Licht abstrahlt, und daß am unteren Rand des Leuchtenschirms ein nach innen ragender, diffus reflektierender Steg vorgesehen ist, der zumindest einen Teil des austretenden Lichts in den Leuchtenschirm zurückreflektiert. This object is achieved in that the optical system in one above the lampshade provided illuminant space is positioned and by a light entry opening at the top of the lampshade shines in this light, and that at the bottom Edge of the lampshade an inwardly protruding, diffuse reflective web is provided, the at least one Part of the emerging light is reflected back into the lampshade.

Bei den bekannten Innenleuchten bestand in bereits beschriebener Weise das Problem, daß sich das Leuchtmittel für einen Betrachter durch den transparenten Schirm als helle Fläche deutlich abgezeichnet hat. Dies wird nun erfindungsgemäß vermieden, indem das Leuchtmittel außerhalb des Lampenschirms in dem Leuchtmittelraum untergebracht ist, mit der Folge, daß eine gleichmäßige Ausleuchtung des Lampenschirms erreicht wird.In the known interior lights existed in the already described Wise the problem that the lamp for a viewer through the transparent screen as has clearly highlighted the bright area. This is now according to the invention avoided by placing the bulb outside of the lampshade housed in the lamp room is, with the result that a uniform illumination of the lampshade is reached.

Dieser Effekt wird noch dadurch verstärkt, daß an dem Steg, welcher an der Lichtaustrittsöffnung des Lampenschirms vorgesehen ist, ein Teil des austretenden Lichtes in den Lampenschirm zurückgeworfen wird, dieser also zusätzlich erhellt wird.This effect is reinforced by the fact that the Web, which at the light outlet opening of the lampshade is provided, part of the emerging light is thrown back into the lampshade, this additionally is illuminated.

Gemäß einer weiteren Ausführungsform der Erfindung besteht der Leuchtenschirm aus lichtdurchlässigem Material, beispielsweise einem Acrylmaterial, das aufgrund seiner Oberflächenstruktur totalreflektienrende Eigenschaften aufweist. Durch diese Oberflächenstruktur wird eine gleichmäßige Ausleuchtung des Lampenschirmes noch unterstützt.According to a further embodiment of the invention the lampshade made of translucent material, For example, an acrylic material that due to its Surface structure totally reflective properties having. This surface structure creates a uniform illumination of the lampshade still supported.

Um die gleichmäßige Ausleuchtung des Leuchtenschirms zu optimieren, kann dieser weiterhin derart ausgebildet und in einem Leuchtmittelraum angebracht sein, daß ein Teil des von dem optischen System abgestrahlten Lichts direkt in das Material des Leuchtenschirms eintritt. To ensure even illumination of the lampshade optimize, this can continue to be trained and be installed in a lamp room that part of the light emitted by the optical system directly enters the material of the lampshade.

Gemäß einer weiteren Ausführungsform ist vorgesehen, daß das Leuchtmittel eine Hochdruck-Entladungslampe in liegender Brennlage ist. Durch den Einsatz solcher Hochdruck-Entladungslampen ist die konzentrierte Erzeugung von hohen Lichtströmen und damit ein hoher Leistungsumsatz auf kleinem Raum möglich. Außerdem erlaubt es der Einsatz solcher Leuchtmittel in liegender Brennlage gegebenenfalls in Kombination mit entsprechenden Reflektoren, die beispielsweise eine batwing-Lichtstärkeverteilung erzeugen, längliche Flächen gleichmäßig auszuleuchten, so daß die Anzahl von Leuchten, die für eine Ausleuchtung einer langgestreckten Präsentationsfläche erforderlich ist, gering gehalten werden kann.According to a further embodiment it is provided that the illuminant is a high-pressure discharge lamp in a lying position Burning position is. By using such high-pressure discharge lamps is the concentrated generation of high luminous flux and thus a high power conversion possible in a small space. It also allows Use of such lamps in the burning position if necessary in combination with appropriate reflectors, which, for example, create a batwing light distribution, Illuminate elongated surfaces evenly, so that the number of lights that are used for illumination an elongated presentation area is required is, can be kept low.

Die Vorschaltgeräte, die beim Einsatz solcher Hochdruck-Entladungslampen erforderlich sind, können beispielsweise in einem benachbart von dem Leuchtmittelraum und insbesondere oberhalb von diesem vorgesehenen Betriebsgeräteraum vorgesehen sein, der von dem Leuchtmittelraum thermisch isoliert ist, so daß die Vorschaltgeräte durch die im Betrieb auftretende Wärmeentwicklung durch das Leuchtmittel nicht beeinträchtigt werden. Beispielsweise können zwischen dem Leuchtmittelraum und dem Betriebsgeräteraum Hitzeschilder vorgesehen sein.The ballasts used when using such high-pressure discharge lamps may be required, for example in an adjacent to the lamp room and in particular above this intended equipment room be provided by the lamp room is thermally insulated so that the ballasts through the heat generated during operation by the Illuminants are not affected. For example can between the lamp room and the equipment room Heat shields may be provided.

Im übrigen kann der Steg am unteren Rand des Leuchtenschirms teilweise lichtdurchlässig sein und das durchgelassene Licht diffus streuen. Beispielsweise kann der Steg wie auch der Lampenschirm aus einem Acrylmaterial bestehen. Otherwise, the web at the bottom of the lampshade partially translucent and the let through Diffuse light. For example, the Bridge as well as the lampshade made of an acrylic material consist.

Schließlich kann der Steg selektiv reflektierend sein, um bestimmte Farbanteile herauszufiltern. In gleicher Weise kann der Lichteintrittsöffnung des Leuchtenschirms ein Filter vorgeschaltet sein, der bestimmte Farbanteile aus dem vom Leuchtmittel abgestrahlten Licht ausfiltert, um die Komplementärfarben zu betonen.Finally, the web can be selectively reflective to filter out certain color components. In the same way the light entry opening of the lampshade Filters upstream of the certain color components filters out the light emitted by the illuminant in order to to emphasize the complementary colors.

Hinsichtlich weiterer vorteilhafter Ausgestaltungen der Erfindung wird auf die Unteransprüche sowie die nachfolgende Beschreibung eines Ausführungsbeispiels unter Bezugnahme auf die beiliegende Zeichnung verwiesen.With regard to further advantageous embodiments of the Invention is based on the dependent claims as well as the following Description of an embodiment with reference refer to the attached drawing.

Die Innenleuchte 1, welche insbesondere zur Ausleuchtug von langgestreckten Flächen wie beispielsweise Tiefkühltruhen, Obstschütten, Verkaufsregalen etc. eingesetzt werden kann, umfaßt einen runden Leuchtenschirm 2 aus einem transparenten Acrylmaterial, der an seiner Oberseite eine kleinere Lichteintrittsöffnung 2a und an seiner Unterseite eine größere Lichtauchstrittsöffnung 2b aufweist. Unter dem Leuchtmittelraum 3 ist mit einem Ansatz 3a der Leuchtschirm 2 angebracht, wobei das Licht durch die Lichteintrittsöffnung 2a in den Leuchtschim eintritt. In dem Leuchtmittelraum 3 ist ein Kastenreflektor 6 üblicher Bauart gehalten, der an seine zur Lichteintrittsöffnung 2a des Leuchtenschirms 2 weisenden Unterseite offen ist. Innerhalb des Reflektors 6 ist in liegender Brennlage eine Hochdruck-Entladungslampe 5 angeordnet, die in eine entsprechende Lampenfassung 4 eingesteckt ist. Die Hochdruck-Entladungslampe 5 kann beispielsweise als Metallhalogendampflampe oder als Natriumhochdrucklampe mit verbesserter Farbwiedergabe ausgebildet sein.In the drawing, the only figure shows an interior lamp according to the present invention in schematic Cross-sectional view. The interior lamp 1, which in particular for illuminating elongated areas such as Freezers, fruit boxes, shelves etc. can be used, includes a round lampshade 2 made of a transparent acrylic material that adheres to a smaller light entry opening 2a on its upper side and a larger light entry opening on its underside 2b. Under the lamp room 3 is with attached a projection 3a of the screen 2, which Light through the light entry opening 2a into the luminous chim entry. In the illuminant room 3 there is a box reflector 6 usual design held to its for Light entrance opening 2a of the lampshade 2 pointing Bottom is open. Inside the reflector 6 is in a high-pressure discharge lamp 5, which is inserted into a corresponding lamp holder 4 is. The high-pressure discharge lamp 5 can for example as a metal halide lamp or as a high pressure sodium lamp trained with improved color rendering his.

Oberhalb des Leuchtmittelraumes 3 ist ein Betriebsgeräteraum 7 vorgesehen, in welchem die Vorschaltgeräte für die Hochdruck-Entladungslampe 5 untergebracht sind. Der Leuchtmittelraum 3 und der Betriebsgeräteraum 7 sind thermisch gegeneinander isoliert. Hierzu sind zwischen den beiden Räumen 3, 7 zwei Hitzeschilder 8 vorgesehen.An operating device room is located above the lamp room 3 7 provided in which the ballasts for the high-pressure discharge lamp 5 are accommodated. The Illuminant room 3 and the equipment room 7 are thermally insulated from each other. For this purpose, between the two rooms 3, 7 two heat shields 8 are provided.

An der offenen Unterseite des Reflektors 6 ist in dem dargestellten Ausführungsbeispiel ein Filter 10 vorgesehen, welcher aus dem Licht vor dem Eintritt in den Lampenschirm 2 bestimmte Farbanteile herausfiltert. Alternativ oder zusätzlich kann auch die Oberfläche des Reflektors 6 selektiv reflektierend sein.On the open bottom of the reflector 6 is in the a filter 10 is provided, which from the light before entering the lampshade Filtered out 2 specific color components. alternative or additionally the surface of the reflector 6 be selective reflective.

Am unteren Rand des Leuchtenschirms 2 ist ein ringförmiger Steg 9 vorgesehen, der in die Lichtaustrittsöffnung 2b hineinragt und diese begrenzt. Dieser Steg 9 besteht aus einem teilweise reflektierenden und teilweise diffus streuenden Material, beispielsweise Acryl.At the bottom of the lampshade 2 is an annular Web 9 provided in the light exit opening 2b protrudes and limits them. This web 9 is made from a partially reflective and partially diffuse scattering material, such as acrylic.

Im Betrieb tritt das von der Hochdruck-Entladungslampe 5 erzeugte Licht gegebenenfalls nach Reflektion an dem Reflektor 6 durch die Lichteintrittsöffnung 2a in den Leuchtenschirm 2 ein, wobei bestimmte Farbanteile durch den Filter 10 ausgefiltert werden. Ein Teil des in den Leuchtenschirm 2 eintretenden Lichts trifft auf den Leuchtenschirm 2 und/oder den Steg 9, wo es entweder in den Leuchtenschirm 2 diffus zurückreflektiert wird oder diffus streuend austritt. Durch die auftretenden Reflektionen und die diffuse Lichtstreuung beim Austritt wird eine gleichmäßige Ausleuchtung des Leuchtenschirms 2 erreicht. Insbesondere wird durch die Unterbringung des Leuchtmittels 5 in dem Leuchtmittelraum 3 außerhalb des Leuchtenschirms 2 erreicht, daß das Leuchtmittel 5 selbst für einen Betrachter nicht unmittelbar sichtbar ist und sich insbesondere nicht als heller Fleck in dem Lampenschirm abzeichnet.In operation, this occurs from the high-pressure discharge lamp 5 generated light if necessary after reflection on the reflector 6 through the light entry opening 2a in the Lampshade 2 on, with certain color components the filter 10 are filtered out. Part of the in the Lampshade 2 entering light hits the Lampshade 2 and / or the bridge 9, where it is either in the lampshade 2 is reflected back diffusely or emerges diffusely scattering. Due to the reflections that occur and the diffuse light scatter at the exit uniform illumination of the lampshade 2 is achieved. In particular, the placement of the Illuminant 5 in the illuminant space 3 outside the Lampshade 2 achieves that the lamp 5 itself is not immediately visible to a viewer and especially not as a bright spot in the lampshade looming.
