Definitions
- the present invention relates to a cover which is intended for use on a lamp housing.
- the invention relates to a cover for use in a so-called. Slotlight light, so an elongated light.
- Luminaires of this type are already known and are realized for example in the form of recessed lights.
- the central element is an elongate or elongated luminaire housing, which is arranged sunk in the mounting hole of a wall or ceiling.
- the aim in these cases is to design the luminaire in such a way that, apart from a translucent cover covering the installation opening, no or as few as possible elements of the luminaire are visible. In this way, quasi-luminous elongated lines of light are created.
- the present invention is based on the object to provide a cover for a luminaire housing available, which on the one hand brings a degree of flexibility and on the other hand meets the optical requirements usually placed on lamp covers.
- the cover consists of silicone, wherein the silicone material glass balls are mixed.
- these glass beads or beads can predominantly have a diameter of about 0.01 mm to 0.50 mm.
- the balls have a diameter of about 0.02 mm.
- covers for luminaires can be obtained by this special combination of materials, which on the one hand have a sufficiently high degree of flexibility and on the other hand satisfy the optical requirements satisfactorily.
- a cover in the case of a slotlight such a cover is sufficiently flexible to adapt to curvatures of the lamp housing.
- the admixture of the glass bead material of the cover gives a sufficiently good degree of transmission while at the same time providing a good resolution of the lamp image. That is, for a viewer of the lamp, the individual light sources arranged therein are no longer recognizable, despite all the cover lets enough light through and accordingly a good efficiency for the lamp is achieved.
- the silicone material may additionally be admixed with white pigments, wherein the pigments may in particular be chalk.
- the pigments may in particular be chalk.
- titanium oxide or zinc oxide could also be added.
- the cover according to the invention may have at its edge regions means for attachment to the lamp housing. This may in particular be two clamping webs arranged on opposite sides.
- the present invention also relates to a luminaire with a luminaire housing whose light exit opening is closed by a corresponding cover.
- the housing may in particular form an elongate channel for receiving one or more light sources, which is closed by the cover.
- the channel may be curved at least over part of its length.
- FIG. 1 shows a detail of an elongated, so-called slotlight 1, in which the cover 2 according to the invention is to be used.
- An essential part of the lamp 1 is a specially designed housing 10, which forms an elongate channel 11 for receiving lamp units.
- These lamp units 20 are arranged by means of special suspension elements 25 in the channel 11, as the sectional view of FIG. 2 shows. Since the length of the housing 10 exceeds the length of a single lamp 21 or lamp unit 20, the lamps 21 are slightly overlapping at their end portions to prevent the occurrence of dark spots.
- the open underside of the channel 11 forms a light exit opening and is covered with an elongate, transparent light emission plate or cover 2.
- This is preferably designed such that the interior of the channel 11 and the lamp units 20 arranged therein are not or almost not recognizable.
- the individual lamp units 20 are arranged substantially continuously in the channel 11, the impression of an elongate continuous luminous line arises.
- LED modules with LEDs arranged behind one another could also be used as light sources instead of the illustrated fluorescent lamps.
- FIG. 1 illustrated lamp 1 is now, however, that the housing 10 can follow curved paths. This is achieved by a special embodiment of the housing 10, which, however, is not the subject of the present invention. In contrast to classic lights, which could extend only along a straight line, so now there is the possibility to integrate the light in curved walls or ceilings and even more complex structures.
- the solution to this problem is to use for the realization of the cover 2 a special combination of materials, which consists of silicone, the glass beads or glass beads are mixed. It has been found that the use of silicone as the base material for the cover provides the desired flexibility. At the same time, by adding the glass spheres, the effect is achieved that the cover as a whole receives a sufficiently good degree of transmittance. That is, sufficient light is transmitted through the cover 2, which is important for achieving a satisfactory efficiency of the luminaire 1.
- the glass beads added to the silicone material preferably have a diameter of about 0.01 mm to 0.50 mm, more preferably the diameter is about 0.02 mm.
- the silicone material may also be admixed with additives which further influence the optical properties of the cover.
- white pigments in the form of chalk, titanium oxide or zinc oxide can be mixed, by which the scattering of the light and thus the resolution of the lamp image is improved. In spite of sufficient transmission, despite sufficient transmission, it is prevented that the lamps 21 arranged in the channel 11 are individually recognizable.
- the attachment of the cover 2 to the housing 10 can, as shown, take place by means of two lateral (clamping) webs 3, which are inserted into corresponding recesses in the underside of the housing 10. These webs may also have a toothing, so that a reliable attitude is guaranteed. Other measures for fixing the cover 2 to the lamp housing 10 would be conceivable.
- the cover according to the invention can of course also be used in luminaire housings extending along a straight line or in large-area housings.
- the particular advantages that result from the use of the inventive combination of materials, however, are used in particular in housings in which a certain curvature of the cover is desired.

Abstract
Description
Die vorliegende Erfindung betrifft eine Abdeckung, die zur Verwendung an einem Leuchtengehäuse vorgesehen ist. Insbesondere betrifft die Erfindung eine Abdeckung zur Verwendung bei einer sog. Slotlight-Leuchte, also einer länglichen Leuchte.The present invention relates to a cover which is intended for use on a lamp housing. In particular, the invention relates to a cover for use in a so-called. Slotlight light, so an elongated light.
Leuchten dieser Art sind bereits bekannt und werden beispielsweise in Form von Einbauleuchten realisiert. Zentrales Element ist ein längliches bzw. langgestrecktes Leuchtengehäuse, welches in der Einbauöffnung einer Wand oder Decke versenkt angeordnet wird. Aus gestalterischen Gründen wird in diesen Fällen angestrebt, die Leuchte derart auszugestalten, dass außer einer die Einbauöffnung überdeckenden lichtdurchlässigen Abdeckung keine oder möglichst wenige Elemente der Leuchte sichtbar sind. Auf diese Weise werden quasi leuchtende längliche Lichtlinien geschaffen.Luminaires of this type are already known and are realized for example in the form of recessed lights. The central element is an elongate or elongated luminaire housing, which is arranged sunk in the mounting hole of a wall or ceiling. For design reasons, the aim in these cases is to design the luminaire in such a way that, apart from a translucent cover covering the installation opening, no or as few as possible elements of the luminaire are visible. In this way, quasi-luminous elongated lines of light are created.
In der modernen Architektur werden häufiger Räume realisiert, welche keine geraden Wand- oder Deckenflächen aufweisen, sondern gewölbt ausgebildet sind. Auch hier ist man bestrebt, die Beleuchtung der Räume durch die zuvor genannten Lichtlinien zu realisieren. Hierfür wurden spezielle Gehäusekonstruktionen geschaffen, welche es erlauben, dass sich das Gehäuse, das üblicherweise einen nach unten bzw. zum Raum hin geöffneten, U-förmigen Kanal bildet, an die gekrümmte Wand- oder Deckenfläche anpasst. Es ergibt sich nunmehr allerdings das Problem, dass sich auch die transparente Abdeckung an die gekrümmte Struktur anpassen muss. Waren bislang eher starre Abdeckungen bekannt, so können diese nun nicht mehr verwendet werden, da sie nicht mehr in der Lage sind, die entsprechenden Krümmungen des Leuchtengehäuses nachzuvollziehen. Auf der anderen Seite müssen die Abdeckungen auch bestimmte optische Eigenschaften aufweisen, durch welche ein Einblick in das Innere des Kanals verhindert ist und gleichzeitig auch das Licht der oftmals hintereinander angeordneten einzelnen Lampen derart gestreut wird, dass die Lampen nicht mehr individuell wahrnehmbar sind.In modern architecture rooms are more often realized, which have no straight wall or ceiling surfaces, but are curved. Again, one strives to realize the lighting of the rooms by the aforementioned light lines. For this purpose, special housing constructions have been created, which allow the housing, which usually forms a U-shaped channel which opens downwards or towards the room, to adapt to the curved wall or ceiling surface. However, the problem now arises that the transparent cover must also adapt to the curved structure. Goods were previously known rather rigid covers, they can not be used now because they are no longer able to understand the corresponding curvatures of the lamp housing. On the other hand, the covers must also have certain optical properties, by which an insight into the interior of the channel is prevented and at the same time the light of the often successively arranged individual lamps is scattered so that the lamps are no longer individually perceptible.
Letztendlich liegt also der vorliegenden Erfindung die Aufgabe zu Grunde, eine Abdeckung für ein Leuchtengehäuse zur Verfügung zu stellen, welche einerseits eine gewisse Flexibilität mit sich bringt und andererseits die üblicherweise an Leuchtenabdeckungen gestellten optischen Anforderungen erfüllt.Ultimately, therefore, the present invention is based on the object to provide a cover for a luminaire housing available, which on the one hand brings a degree of flexibility and on the other hand meets the optical requirements usually placed on lamp covers.
Die Aufgabe wird durch eine Abdeckung für ein Leuchtengehäuse mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der abhängigen Ansprüche.The object is achieved by a cover for a lamp housing with the features of claim 1. Advantageous developments of the invention are the subject of the dependent claims.
Erfindungsgemäß wird vorgeschlagen, dass die Abdeckung aus Silikon besteht, wobei dem Silikonmaterial Glaskugeln beigemischt sind. Insbesondere können diese Glaskugeln bzw. -perlen überwiegend einen Durchmesser von etwa 0,01mm bis 0,50 mm aufweisen. Bevorzugt weisen die Kugeln einen Durchmesser von etwa 0,02 mm auf.According to the invention it is proposed that the cover consists of silicone, wherein the silicone material glass balls are mixed. In particular, these glass beads or beads can predominantly have a diameter of about 0.01 mm to 0.50 mm. Preferably, the balls have a diameter of about 0.02 mm.
Es hat sich gezeigt, dass durch diese spezielle Materialkombination Abdeckungen für Leuchten erhalten werden können, welche einerseits eine hinreichend hohe Flexibilität aufweisen und andererseits die optischen Anforderungen in zufriedenstellender Weise erfüllen. Insbesondere im Falle einer Slotlight-Leuchte ist eine derartige Abdeckung ausreichend flexibel, um sich auch Krümmungen des Leuchtengehäuses anzupassen. Gleichzeitig verleiht allerdings die Beimischung des Glasperlenmaterials der Abdeckung einen ausreichend guten Transmissionsgrad bei gleichzeitiger guter Auflösung des Lampenbilds. D.h., für einen Betrachter der Leuchte sind die darin angeordneten einzelnen Lichtquellen nicht mehr erkennbar, wobei trotz allem die Abdeckung ausreichend Licht durchlässt und dementsprechend eine gute Effizienz für die Leuchte erzielt wird.It has been found that covers for luminaires can be obtained by this special combination of materials, which on the one hand have a sufficiently high degree of flexibility and on the other hand satisfy the optical requirements satisfactorily. In particular, in the case of a slotlight such a cover is sufficiently flexible to adapt to curvatures of the lamp housing. At the same time, however, the admixture of the glass bead material of the cover gives a sufficiently good degree of transmission while at the same time providing a good resolution of the lamp image. That is, for a viewer of the lamp, the individual light sources arranged therein are no longer recognizable, despite all the cover lets enough light through and accordingly a good efficiency for the lamp is achieved.
Gemäß einer vorteilhaften Weiterbildung der Erfindung können dem Silikonmaterial zusätzlich weiße Pigmente beigemischt sein, wobei es sich bei den Pigmenten insbesondere um Kreide handeln kann. Alternativ hierzu könnte auch Titanoxid oder Zinkoxid beigemischt werden.According to an advantageous development of the invention, the silicone material may additionally be admixed with white pigments, wherein the pigments may in particular be chalk. Alternatively, titanium oxide or zinc oxide could also be added.
Ferner kann die erfindungsgemäße Abdeckung an ihren Randbereichen Mittel zur Befestigung an dem Leuchtengehäuse aufweisen. Es kann sich hierbei insbesondere um zwei an einander gegenüberliegenden Seiten angeordnete Klemmstege handeln.Furthermore, the cover according to the invention may have at its edge regions means for attachment to the lamp housing. This may in particular be two clamping webs arranged on opposite sides.
Erfindungsgemäß betrifft die vorliegende Erfindung auch eine Leuchte mit einem Leuchtengehäuse, dessen Lichtaustrittsöffnung durch eine entsprechende Abdeckung verschlossen ist. Dabei kann das Gehäuse insbesondere einen länglichen Kanal zur Aufnahme einer oder mehrerer Lichtquellen bilden, der durch die Abdeckung verschlossen ist. Insbesondere kann der Kanal zumindest über einen Teil seiner Länge hinweg gekrümmt sein.According to the invention, the present invention also relates to a luminaire with a luminaire housing whose light exit opening is closed by a corresponding cover. In this case, the housing may in particular form an elongate channel for receiving one or more light sources, which is closed by the cover. In particular, the channel may be curved at least over part of its length.
Nachfolgend soll die Erfindung anhand der beiliegenden Zeichnung näher erläutert werden. Es zeigen:

FIG. 1 in section.
Die offene Unterseite des Kanals 11 bildet eine Lichtaustrittsöffnung und ist mit einer länglichen, transparenten Lichtemissionsplatte bzw. Abdeckung 2 abgedeckt. Diese ist vorzugsweise derart ausgestaltet, dass das Innere des Kanals 11 bzw. die darin angeordneten Lampeneinheiten 20 nicht oder nahezu nicht erkennbar sind. Werden also die einzelnen Lampeneinheiten 20 im Wesentlichen kontinuierlich in dem Kanal 11 angeordnet, so entsteht der Eindruck einer langgestreckten durchgehenden leuchtenden Linie. Anzumerken ist, dass anstelle der dargestellten Leuchtstofflampen selbstverständlich auch LED-Module mit hintereinander angeordneten LEDs als Lichtquellen zum Einsatz kommen könnten.The open underside of the
Bislang bestanden entsprechende Lichtemissionsplatten aus einem transparenten Kunststoff, beispielsweise Polykarbonat. Eine Besonderheit der in
Es ergibt sich nunmehr allerdings das Problem, dass eine starre Lichtemissionsplatte der gekrümmten Bahn des Leuchtengehäuses 10 nicht mehr folgen kann. Dementsprechend wird erfindungsgemäß eine neuartige Abdeckung vorgeschlagen, welche diese Möglichkeit bietet und gleichzeitig auch den optischen Anforderungen einer transparenten Lichtemissionsplatte entspricht.However, there is now the problem that a rigid light-emitting plate of the curved path of the
Die Lösung dieser Aufgabe besteht darin, zur Realisierung der Abdeckung 2 eine spezielle Materialkombination zu verwenden, welche aus Silikon besteht, dem Glasperlen bzw. Glaskugeln beigemischt sind. Es hat sich gezeigt, dass durch die Verwendung von Silikon als Grundmaterial für die Abdeckung die gewünschte Flexibilität erreicht wird. Gleichzeitig wird durch das Beimischen der Glaskugeln der Effekt erzielt, dass die Abdeckung insgesamt einen ausreichend guten Transmissionsgrad erhält. D.h., es wird ausreichend Licht durch die Abdeckung 2 durchgelassen, was zum Erzielen einer zufriedenstellenden Effizienz der Leuchte 1 wichtig ist.The solution to this problem is to use for the realization of the cover 2 a special combination of materials, which consists of silicone, the glass beads or glass beads are mixed. It has been found that the use of silicone as the base material for the cover provides the desired flexibility. At the same time, by adding the glass spheres, the effect is achieved that the cover as a whole receives a sufficiently good degree of transmittance. That is, sufficient light is transmitted through the
Die dem Silikonmaterial beigefügten Glasperlen weisen vorzugsweise einen Durchmesser von etwa 0,01mm bis 0,50mm auf, besonders bevorzugt beträgt der Durchmesser etwa 0,02mm. Ferner können dem Silikonmaterial zusätzlich auch noch Zusatzstoffe beigemischt werden, welche die optischen Eigenschaften der Abdeckung weiter beeinflussen. Insbesondere können weiße Pigmente in Form von Kreide, Titanoxid oder Zinkoxid beigemischt werden, durch welche die Streuung des Lichts und damit die Auflösung des Lampenbilds verbessert wird. Bei ausreichender Transmission ist also trotz allem verhindert, dass die in dem Kanal 11 angeordneten Lampen 21 einzeln erkennbar sind.The glass beads added to the silicone material preferably have a diameter of about 0.01 mm to 0.50 mm, more preferably the diameter is about 0.02 mm. In addition, the silicone material may also be admixed with additives which further influence the optical properties of the cover. In particular, white pigments in the form of chalk, titanium oxide or zinc oxide can be mixed, by which the scattering of the light and thus the resolution of the lamp image is improved. In spite of sufficient transmission, despite sufficient transmission, it is prevented that the
Die Befestigung der Abdeckung 2 an dem Gehäuse 10 kann- wie dargestellt- mittels zweier seitlicher (Klemm-)Stege 3 erfolgen, welche in entsprechende Ausnehmungen in der Unterseite des Gehäuses 10 eingeführt werden. Diese Stege können ferner auch eine Verzahnung aufweisen, sodass eine zuverlässige Haltung gewährleistet ist. Auch andere Maßnahmen zur Befestigung der Abdeckung 2 an dem Leuchtengehäuse 10 wären denkbar.The attachment of the
Abschließend ist ferner auch darauf hinzuweisen, dass die erfindungsgemäße Abdeckung selbstverständlich auch bei sich entlang einer Geraden erstreckenden Leuchtengehäusen oder bei großflächigen Gehäusen zum Einsatz kommen kann. Die besonderen Vorteile, die sich durch die Verwendung der erfinderischen Materialkombination ergeben, kommen allerdings insbesondere bei Gehäusen zum Einsatz, bei denen eine gewisse Krümmung der Abdeckung gewünscht ist.Finally, it should also be pointed out that the cover according to the invention can of course also be used in luminaire housings extending along a straight line or in large-area housings. The particular advantages that result from the use of the inventive combination of materials, however, are used in particular in housings in which a certain curvature of the cover is desired.
