Description

Die Erfindung betrifft eine Rasterblende für Beleuchtungseinrichtungen, die aus einer Wabenrasterscheibe besteht, gemäß dem Oberbegriff des Anspruches 1.The invention relates to a grid aperture for illumination devices, which consists of a honeycomb grid plate, according to the preamble of claim 1.

Bekannt sind diverse Rasterblenden, die in einem bemessenem Abstand zur Leuchtquelle, insbesondere Langfeldleuchten direkt am Leuchtkörpergehäuse angebracht sind.Various grid screens are known, which are mounted at a measured distance from the light source, in particular linear lamps directly on the lamp housing.

Aus der EP 0 819 232 B1 ist ein Vorsatz für freistrahlende Miniaturreflektoren bekannt, bei dem ein Auflageelement mit Lichtlenkbauteilen, beispielsweise Rippen, auf dem Reflektorrand angeordnet ist und über Klemmelemente unterhalb des Reflektorrandes formschlüssig befestigt wird. Dieser Vorsatz ist für genormte Beleuchtungseinrichtungen mit Steg und anti-blend Kappen nur geeignet, wenn der untere Reflektorrand zugänglich und nicht verbaut ist. Für größere Beleuchtungseinheiten ist diese Lösung nicht geeignet.From the EP 0 819 232 B1 is a header for free-radiating miniature reflectors known in which a support element with light-guiding components, such as ribs, is arranged on the reflector edge and is positively secured by clamping elements below the edge of the reflector. This attachment is only suitable for standardized lighting equipment with bar and anti-glare caps if the lower edge of the reflector is accessible and not installed. For larger lighting units, this solution is not suitable.

Für eine Beleuchtungseinrichtung mit Steg und anti-blend Kappe ist eine Befestigungsklemme nach DE 203 06 703 U1 bekannt, die mittels Klammern einen blattartigen Körper an dem Steg befestigt. Der blattartige Körper hat in seiner Mitte eine Befestigung für Filterscheiben vorgesehen. Nachteilig bei dieser Ausführung ist die formschlüssige und damit nicht ausreichend feste Verbindung des blattartigen Körpers mit dem Steg der Beleuchtungseinrichtung. Der Abstand des befestigten Filters zu der Lichtquelle und der anti-blend Kappe ist derart, dass unterhalb der anti-blend Kappe seitlich austretendes Licht den Betrachter blenden kann. Diesen Nachteil hat zugleich die bekannte Ausführung nach EP 1 156 269 B1 .For a lighting device with bar and anti-glare cap is a mounting clamp to DE 203 06 703 U1 known, which attaches a sheet-like body to the web by means of brackets. The sheet-like body has provided in its center a fixture for filter discs. A disadvantage of this design is the positive and thus not sufficiently strong connection of the sheet-like body with the web of the lighting device. The distance of the attached filter to the light source and the anti-glare cap is such that laterally exiting light below the anti-glare cap can blind the viewer. This disadvantage has at the same time the known design EP 1 156 269 B1 ,

Nach DE 295 01 521 U1 ist eine Beleuchtungseinrichtung bekannt, bei der bereits eine Vorrichtung zur Befestigung der Filterscheibe direkt am Rand des Reflektors angeordnet ist. Das umlaufende Bauteil besteht aus nichtelastischem jedoch flexiblem Material und ist formschlüssig mit dem Rand des Reflektors verbunden. Dieses Bauteil umschließt die Filterscheibe und distanziert die Scheibe von der Lichtquelle. Nachteilig bei dieser Ausführung des Halte- und Abstandringes ist die formschlüssige Befestigung unterhalb des Reflektorringes durch Reflektorhaltekrallen. Entsprechend der Ausbildung des unteren Randes des Reflektorringes müssen jeweils die Reflektorkrallen angepasst werden. Bei den meisten bekannten Leuchten ist der untere Randbereich durch weitere Konstruktionselemente verbaut und für Reflektorkrallen nicht mehr zugänglich. Grundsätzlich stellt sich der Nachteil heraus, dass bei Reflektorlampen mit nicht oder nur ansatzweise ausgebildeten bzw. verdeckten unteren Rändern die Reflektorkrallen nur schwerlich dem Reflektorring angepasst werden können. Außerdem ist bei der Befestigung mit Krallen eine lockere Befestigung nicht auszuschließen und bei stärkerer Krafteinwirkung sogar ein Abheben des Reflektorringes nicht ausgeschlossen. Diese bekannte Haltevorrichtung ist zwar geeignet für die Aufnahme von Wabenrasterscheiben, hat aber den Nachteil, dass sie nicht anwendbar ist für genormte Beleuchtungseinrichtungen mit über den Reflektorrand ragendem Steg und anti-blend Kappe, da die Kappe und der Steg bei diesen Einrichtungen über den Rand des Reflektors hinausragen.To DE 295 01 521 U1 a lighting device is known in which already a device for fixing the filter disc directly on Edge of the reflector is arranged. The peripheral component is made of non-elastic but flexible material and is positively connected to the edge of the reflector. This component encloses the filter disk and distances the disk from the light source. A disadvantage of this embodiment of the holding and spacer ring is the positive fastening below the reflector ring by reflector holding claws. According to the design of the lower edge of the reflector ring, the reflector claws must be adapted in each case. In most known lights, the lower edge area is installed by other construction elements and no longer accessible for reflector claws. Basically, the disadvantage arises that in reflector lamps with not or only partially formed or hidden lower edges, the reflector claws can be difficult to adjust the reflector ring. In addition, a loose attachment can not be excluded in the attachment with claws and not even excluded a lifting of the reflector ring with stronger force. Although this known holding device is suitable for receiving honeycomb louvres, but has the disadvantage that it is not applicable to standardized lighting devices with ragendem over the edge of the reflector ridge and anti-glare cap, since the cap and the web at these facilities on the edge of the Protrude reflector.

Die aufgesetzten Blenden der bekannten Beleuchtungseinrichtungen haben konstruktiv bedingt den Nachteil, dass ein relativ großer Abstand zum Leuchtkörper hin besteht und dadurch bedingt, seitliche Abstrahlungen nicht vermieden werden. Diese seitlichen Abstrahlungen wurden auch mit den bekannten Lösungen für Beleuchtungseinrichtungen mit genormten Stegen und anti-blend Kappen nicht beseitigt. Die unterhalb der zentral angeordneten Kappe seitlich austretenden Strahlen können ungehindert unterhalb der Blenden austreten.The patch panels of the known lighting devices have the disadvantage that a relatively large distance from the luminous body is due to the design and therefore, lateral emissions are not avoided. These lateral radiations were not eliminated even with the known solutions for lighting devices with standardized bars and anti-blend caps. The rays emerging laterally below the centrally arranged cap can exit unhindered below the baffles.

Aufgabe der Erfindung ist es, eine sichere Aufnahme der Wabenrasterscheibe und eine Befestigung der Rasterblende für eine Vielzahl von genormten Beleuchtungseinrichtungen zu schaffen, die mit dem Rand der Reflektorlampe kraftschlüssig verbunden ist, eine Wabenscheibe zugleich formschlüssig hält und die Rasterblende dabei so ausgebildet ist, dass eine Anordnung der Wabenrasterscheibe trotz hoch liegendem Steg möglich ist und somit störende seitliche Abstrahlungen gemindert bzw. ganz vermieden werden.The object of the invention is to provide a secure recording of the honeycomb grid and attachment of the grid aperture for a variety of standardized lighting devices, which is non-positively connected to the edge of the reflector lamp, a honeycomb disc also holds form-fitting and the grid aperture is designed so that a Arrangement of the honeycomb grid plate despite high-lying web is possible and thus annoying lateral emissions are reduced or avoided altogether.

Die Erfindung ist für alle Reflektorlampen mit vereinheitlichter Randausbildung, wie z.B. die Aluminium-Reflektorlampe 111 mm, besonders geeignet. Einziges Maß für die Anpassung ist der Durchmesser des oberen Reflektorrandes.The invention is applicable to all reflector lamps with unified edge formation, such as e.g. the aluminum reflector lamp 111 mm, particularly suitable. The only measure of the adjustment is the diameter of the upper reflector edge.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruches gelöst, d.h., dass die Wabenrasterscheibe der Rasterblende mit einer ausgestanzten Öffnung versehen ist und die Rasterblendenbefestigung aus Federbügeln besteht, die jeweils mit einer Seite am umlaufenden Bauteil beidseitig fest verbunden sind und mit den zur Mitte gerichteten gekröpften Bügelenden durch die ausgestanzte mittlere Öffnung der Wabenrasterscheibe hindurchgreifen und unter den Steg der Beleuchtungseinrichtung haken und die Rasterblende auf den Rand der Reflektorlampe andrückt, wobei die beidseitigen schlüssellochähnlichen Aussparungen über den Steg hinweggestülpt angeordnet sind, so dass die tiefgelegene Wabenrasterscheibe das unterhalb der Kappe austretende seitliche Streulicht absorbiert.This object is achieved by the features of claim, that is, the honeycomb grid plate of the grid is provided with a punched opening and the Rasterblendenbefestigung consists of spring clips, which are firmly connected on both sides with one side on the rotating component and with the centered cranked Tongue ends pass through the punched-out central opening of the honeycomb grid and hook under the bridge of the illumination device and presses the grid aperture on the edge of the reflector lamp, the two-sided keyhole-like recesses are arranged weggedülpt over the web, so that the low-lying honeycomb grid emerging from below the cap side scattered light absorbed.

Nach Fig.1 besteht die bekannte Beleuchtungseinheit aus einer Reflektorlampe 1 mit am Reflektor 13 fest angeordnetem Steg 3 . Am Steg 3 ist zentral eine anti-blend Kappe 2 befestigt. In die Kappe 2 ragt der obere Teil der Leuchtquelle 14 hinein. Der äußere obere Rand 7 der Reflektorlampe 1 ist wie auch der Steg 3, die Kappe 2 mit den konstruktiven Abmaßen und Zuordnungen genormt. Der obere Rand 7 der Reflektorlampe 1 bildet einen ringförmigen, stufenförmigen Absatz, der auch bei Einbau der Reflektorlampe 1 aus dem Gebilde herausragt.According to FIG. 1, the known illumination unit consists of a reflector lamp 1 with a web 3 fixedly arranged on the reflector 13. At the bridge 3, an anti-glare cap 2 is attached centrally. In the cap 2, the upper part of the light source 14 protrudes. The outer upper edge 7 of the reflector lamp 1 is standardized as well as the web 3, the cap 2 with the structural dimensions and assignments. The upper edge 7 of the reflector lamp 1 forms an annular stepped step which protrudes from the structure even when the reflector lamp 1 is installed.

Die Rasterblende nach Fig.2, 3 und 4 besteht aus einem umlaufenden Bauteil 4 mit oberen und unteren Scheibenhaltern 6. Die Scheibenhalter 6 distanzieren im abgewinkelten Zustand eine dazwischen eingelegte Wabenrasterscheibe 5. An der Peripherie des Bauteiles 4 sind Federbügel 10 zur Rasterblendenbefestigung vorgesehen. Die Federbügel 10 sind an dem umlaufenden Bauteil 4 fest angebracht und zur Mitte hin als Bügelenden 11 gekröpft und um 90 ° verdreht ausgebildet. Die feste Anordnung der Federbügel 10 an dem Bauteil 4 erfolgt vorteilhafter Weise durch Punktschweißung. Dazu werden die Enden der Federbügel 10 zu einer in der Zeichnung nicht dargestellten Öse geformt. In die Wabenrasterscheibe 5 ist eine mittige Öffnung 9 ausgestanzt, die seitliche schlüssellochartige Aussparungen 8 aufweist. Die Rasterblende ist im montierten Zustand als eine in sich kompakte Einrichtung ausgebildet.The screen plate according to Fig.2, 3 and 4 consists of a peripheral component 4 with upper and lower disc holders 6. The disc holder 6 in the angled state a spaced inbetween honeycomb screen disc 5. At the periphery of the component 4 spring clip 10 are provided for raster aperture attachment. The spring clip 10 are fixedly attached to the rotating component 4 and cranked toward the center as strap ends 11 and formed rotated by 90 °. The fixed arrangement of the spring clip 10 on the component 4 is advantageously carried out by spot welding. For this purpose, the ends of the spring clip 10 are formed into an eyelet, not shown in the drawing. In the honeycomb grid disk 5, a central opening 9 is punched out, the side keyhole-like recesses 8 has. The grid aperture is formed in the assembled state as a self-compact device.

Zur Komplettierung mit der handelsüblichen Reflektorlampe 1 sind lediglich die Abmaße des Durchmessers des stufenförmigen Randes 7 bei der Ausbildung des Bauteiles 4 einzuhalten. Die Öffnung 9, die schlüssellochartigen Aussparungen 8 und die Federbügel 10 sind Durchmesser abhängige Maße und können für beliebige Durchmesser der Reflektorlampen 1 komplett vorgefertigt werden.For completion with the commercially available reflector lamp 1 are only the dimensions of the diameter of the stepped edge. 7 to comply with the training of the component 4. The opening 9, the keyhole-like recesses 8 and the spring clip 10 are diameter-dependent dimensions and can be completely prefabricated for any diameter of the reflector lamps 1.

Die dem Durchmesser der Reflektorlampe 1 angepasste Rasterblende wird auf den stufenförmigen Rand 7 der Reflektorlampe 1 aufgesetzt und befestigt, in der Art, dass die schlüssellochartigen Aussparungen 8 der Wabenrasterscheibe 5 jeweils über den Steg 3 gestülpt werden und der Steg 3 somit in die Wabenrasterscheibe 5 hineinreicht. Die in die ausgestanzte Öffnung 9 hineinragenden Federbügel 10 werden von Hand mit ihren gekröpften Bügelenden 11 unter den Steg 3 der Reflektorlampe 1 eingehakt. Damit ist die Montage der Rasterblende abgeschlossen. Die Rasterblende ist über die Federbügel 10 kraftschlüssig mit der Reflektorlampe 1 und die Wabenrasterscheibe 5 durch die oberen und unteren Scheibenhalter 6 formschlüssig mit dem Bauteil 4 verbunden.The diameter of the reflector lamp 1 adapted grid aperture is placed and fixed on the stepped edge 7 of the reflector lamp 1, in such a way that the keyhole-like recesses 8 of the honeycomb grid plate 5 are slipped over the web 3 and thus the web 3 extends into the honeycomb grid 5 , The projecting into the punched opening 9 spring clip 10 are hooked by hand with their bent temple ends 11 under the web 3 of the reflector lamp 1. This completes the assembly of the screen. The grid aperture is frictionally connected via the spring clip 10 with the reflector lamp 1 and the honeycomb grid plate 5 by the upper and lower disc holder 6 with the component 4.

Nach Fig.4 werden die unterhalb der Kappe 2 seitlich vorhandenen störenden Blendstrahlen 12 der Leuchtquelle 14 durch die Wabenrasterscheibe 5 absorbiert, während die reflektierten Nutzstrahlen 15 durch die Wabenrasterscheibe 5 hindurchgelassen werden.4, the laterally present below the cap 2 interfering glare rays 12 of the light source 14 are absorbed by the honeycomb screen 5, while the reflected useful rays 15 are passed through the honeycomb grid disk 5.

Vorteilhaft ist die Rasterblende dadurch, dass sie störende seitliche Blendung ausschließt, als kompakt vorgefertigtes Nachrüstteil ausgebildet und lieferbar ist, leicht montier- und demontierbar ist, kraftschlüssig mit der Reflektorlampe 1 verbunden ist, dass durch die überragenden Federbügel 10 zusätzlich eine Distanzierung zu Gegenständen erreicht wird und somit die Gefahr eines Überhitzens bei zu geringem Abstand verringert wird, nur ein Anschlussparameter ausreicht, um vorgefertigt auf die genormten Reflektorlampen 1 angebracht zu werden. Die kompakte Rasterblende ist durch die Verwendung weniger Bauteile vorteilhaft als leichte Einheit ausgebildet.Advantageously, the grid aperture is characterized in that it excludes annoying lateral glare, as compact prefabricated retrofit part is designed and deliverable, easy to assemble and disassemble, non-positively connected to the reflector lamp 1, that in addition a distancing to objects is achieved by the superior spring clip 10 and thus the risk of overheating at too small a distance is reduced, only one connection parameter is sufficient to prefabricated on the standard reflector lamps. 1 to be attached. The compact grid aperture is advantageously formed by the use of fewer components as a lightweight unit.
