Description
Die Erfindung betrifft eine Einbauleuchte nach dem Oberbegriff des Anspruchs 1. Solche Leuchten können mittels bekannter Nivellierungsvorrichtung in eine Decke oder dergleichen eingebaut werden. Beispielsweise ist eine derartige Nivellierungseinrichtung in der europäischen Patentanmeldung
Leuchten der eingangs genannten Art bestehen aus einem Leuchtengehäuse, welches zur Aufnahme wenigstens eines Leuchtmittels, von Betriebs- und Steuergeräten und lichtleitender oder lichtlenkender Komponenten geeignet ist. Solche Leuchtengehäuse weisen Lichtaustrittsfenster auf, um den Lichtaustritt zu ermöglichen. Lichtlenkende und/oder lichtleitende Komponenten, wie Leuchtenraster und Mikrooptiken sorgen für die angestrebte Lichtverteilung und dienen beispielsweise der Entblendung. Es ist bereits bekannt, derartige Leuchten mittels einer lichtdurchlässigen Abdeckung zu verschließen, um beispielsweise die Verschmutzung des Leuchteninneren, insbesondere der Lichtlenkenden bzw. Lichtleitenden Komponenten zu verhindern.
Insbesondere sind derartige Leuchten aus der
Weil die Verschmutzung von Leuchten getrieben durch gesetzliche bzw. normative Vorgaben, wie beispielsweise die Berücksichtigung eines Verschmutzungsfaktors bei der Auslegung von Beleuchtungsanlagen ein immer wichtigeres Thema wird, beseht ein Bedarf nach verbesserten, kostengünstigen Verschlusseinrichtungen für Abdeckungen, weil geschlossene Leuchten hinsichtlich des Verschmutzungsfaktors Vorteile haben.Luminaires of the type mentioned above consist of a luminaire housing, which is suitable for receiving at least one light source of operating and control devices and light-conducting or light-directing components. Such luminaire housings have light exit windows to allow the light to exit. Light-directing and / or light-conducting components, such as light grids and micro-optics ensure the desired light distribution and are used, for example, to glare. It is already known to close such lights by means of a translucent cover, for example, to prevent the pollution of the lamp interior, in particular the light-directing or light-conducting components.
In particular, such lights are from the
Because the pollution of lights driven by legal or normative requirements, such as Considering a pollution factor in the design of lighting systems is an increasingly important issue, there is a need for improved, cost-effective closure devices for covers, because closed lights have advantages in terms of pollution factor.
Es ist Aufgabe der Erfindung, eine Einbauleuchte gemäß Oberbegriff des Anspruchs 1 derart weiterzubilden, dass mittels einer Abdeckung auf einfache Art und Weise verschlossen werden kann.It is an object of the invention to develop a recessed light according to the preamble of claim 1 such that can be closed by means of a cover in a simple manner.
Die Aufgabe wird gelöst mit den kennzeichnenden Merkmalen des Anspruchs 1. Hierbei besteht die Abdeckung aus einem Rahmen und einem lichtdurchlässigen Element, insbesondere einer Glasplatte. Der Rahmen fasst das lichtdurchlässige Element ein. Am Rahmen sind Verschlusselemente angebracht, die mit Verschlussöffnungen im umlaufenden Rand des Leuchtengehäuses zusammenwirken, um die Abdeckung lösbar am Leuchtengehäuse zu befestigen.The object is achieved with the characterizing features of claim 1. Here, the cover consists of a frame and a translucent element, in particular a glass plate. The frame captures the translucent element. On the frame closure elements are mounted, which cooperate with shutter openings in the peripheral edge of the lamp housing to releasably secure the cover to the lamp housing.
Ein wesentlicher Gedanke der Erfindung ist es, den umlaufenden Rand einer Einbauleuchte derart auszugestalten, dass im Bereich dieses Randes genügend Raum vorhanden ist, um Gegenelemente für einen Verschluss, also im konkreten Fall Verschlussöffnungen, unterbringen zu können. Ist der Rahmen der Abdeckung nun so ausgebildet, dass dieser auch den umlaufenden Rand des Leuchtengehäuses überdeckt, ist eine Möglichkeit geschaffen, um Verschlusselements und Verschlussöffnungen beim Zusammenbau ineinander greifen zu lassen.An essential idea of the invention is to configure the peripheral edge of a recessed luminaire in such a way that sufficient space is available in the region of this edge in order to be able to accommodate counter-elements for a closure, ie in this specific case shutter openings. If the frame of the cover is now designed such that it also covers the peripheral edge of the luminaire housing, a possibility is created for the closure element and closure openings to engage in one another during assembly.
Erfindungsgemäß ist das Verschlusselement als Haltefeder ausgebildet, welche einen Basisabschnitt und zwei Federschenkel aufweist. Die Federschenkel der Haltefeder haben vorzugsweise im Bereich der freien Enden erste, zueinander geneigte Abschnitte und anschließend an diese Abschnitte zweite Abschnitte, die divergent auseinander laufen. Ferner kann die Haltefeder in Stirnansicht im Wesentlichen U-förmig ausgestaltet sein, wobei sich dem Basisabschnitt Federschenkel anschließen, die zumindest in einem Teilabschnitt parallel zueinander ausgerichtet sind. Die zuvor beschriebenen Ausführungsformen der Haltefeder ermöglichen es, dass die Haltefeder in die Verschlussöffnung werkzeuglos eingeclipst werden kann. Es ist damit möglich, die Abdeckung einfach gegen das Leuchtengehäuse zu drücken und durch Überdrücken der Haltefedern zu schließen. Die Federschenkel gleiten beim Gegeneinanderdrücken von Abdeckung und Leuchtengehäuse, geführt durch die geneigten Abschnitte dieser entlang der Verschlussöffnung und werden dadurch so lange gegeneinander gedrückt, bis der an der Verschlussöffnung entlang gleitende Abschnitt übergeht in einen divergenten Abschnitt, mit der Folge dass, die Federwirkung der Haltefeder nun die Federschenkel voneinander weg drückt, wodurch diese die Verschlussöffnung hintergreifen.According to the invention the closure element is designed as a retaining spring, which has a base portion and two spring legs. The spring legs of the retaining spring preferably have in the region of the free ends first, mutually inclined portions and then to these sections second portions which divergently divergent. Furthermore, the retaining spring in front view may be configured substantially U-shaped, wherein the Base section connecting spring leg, which are aligned parallel to each other at least in a section. The embodiments of the retaining spring described above make it possible for the retaining spring to be clipped into the closure opening without tools. It is thus possible to simply press the cover against the lamp housing and close by overpressure of the retaining springs. The spring legs slide when pressed against each other of the cover and the lamp housing, guided by the inclined portions of these along the closure opening and are thereby pressed against each other until the sliding along the closure opening portion merges into a divergent section, with the result that, the spring action of the retaining spring now presses the spring legs away from each other, whereby they engage behind the closure opening.
Um die Abdeckung zu verschließen, ist es daher notwendig, dass im zusammengebauten Zustand von Leuchtengehäuse und Abdeckung die Federschenkel der Haltefeder in die Verschlussöffnungen soweit eingreifen, bis diese mit ihren divergent auseinander laufenden Abschnitten die Verschlussöffnung hintergreifen.In order to close the cover, it is therefore necessary that in the assembled state of the lamp housing and cover, the spring legs of the retaining spring engage in the closure openings until they engage behind the closure opening with their divergent sections running apart.
In einer Weiterbildung der Erfindung kann die Haltefeder Öffnungen zur Befestigung einer Abhängesicherung aufweisen. Diese Öffnungen befinden sich bevorzugt in dem Teilabschnitt der Federschenkel, wo diese parallel zueinander ausgerichtet sind. Die Abhängesicherung kann in bekannter Weise mit einer Spiralfeder realisiert sein. Diese ist mit ihrem einen Ende mit der Haltefeder und mit ihrem anderen Ende mit der Abdeckung verbunden, wobei die Abdeckung eine Freinehmung aufweist, um der Spiralfeder in zusammengebautem Zustand von Leuchtengehäuse und Abdeckung Raum zu geben. Somit kann die Abhängesicherung verhindern, dass eine Abdeckung, die sich vom Leuchtengehäuse gelöst unkontrolliert nach untern fallen kann. Wesentlich hierbei ist, dass durch die Freinehmung, die Spiralfeder zwischen Rahmen und umlaufenden Rand des Leuchtengehäuses untergebracht werden kann und somit in zusammengebauten Zustand von außen nicht sichtbar ist.In a development of the invention, the retaining spring can have openings for fastening a suspension guard. These openings are preferably in the section of the spring legs, where they are aligned parallel to each other. The suspension can be realized in a known manner with a coil spring. This is connected at one end to the retaining spring and at the other end to the cover, wherein the Cover has a clasp to give the coil spring in the assembled state of the lamp housing and cover space. Thus, the hanger can prevent a cover that can fall from the luminaire housing solved uncontrolled fall down. It is essential here that can be accommodated by the Freinehmung, the coil spring between the frame and the peripheral edge of the lamp housing and thus is not visible in the assembled state from the outside.
In vorteilhafter Weise können bei einer erfindungsgemäßen Einbauleuchte Vorkehrungen getroffen werden, damit die Abdeckung beim Zusammenbau nicht beschädigt wird. Hierzu kann beispielsweise vorgesehen sein, dass die maximal mögliche Eindringtiefe der Haltefeder in die Verschlussöffnung der Abdeckung kleiner ist, als die Höhe des Kragens des umlaufenden Randes. Außerdem wäre es möglich die Federschenkel der Haltefeder schmaler auszubilden als deren Basisabschnitt, um die dadurch gebildeten Rücksprünge als Anschläge zu verwenden. Die Anschläge begrenzen im Zusammenspiel mit den Verschlussöffnungen die maximale Eindringtiefe.Advantageously, provision can be made in a recessed luminaire according to the invention, so that the cover is not damaged during assembly. For this purpose, for example, be provided that the maximum possible penetration depth of the retaining spring in the closure opening of the cover is smaller than the height of the collar of the peripheral edge. In addition, it would be possible to form the spring legs of the retaining spring narrower than the base portion to use the recesses formed as attacks. The stops limit the maximum penetration depth in interaction with the shutter openings.
Erfindungsgemäß kann das lichtdurchlässige Element der Abdeckung als Glasplatte ausgebildet sein, die mit dem Rahmen verklebt ist, wobei unter Glasplatte herkömmliche Glasplatten aber auch durchsichtige Kunststoffplatten zu verstehen sind.According to the invention, the light-transmissive element of the cover may be formed as a glass plate which is glued to the frame, wherein glass plate conventional glass plates but also transparent plastic plates are to be understood.
Als Leuchtmittel kann zumindest eine Leuchtstofflampe eingesetzt werden, wobei diese bevorzugt mittels Leuchtraster in bekannter Art und Weise entblendet ist. Alternativ sind auch als Leuchtmittel auch mehrere Leuchtdioden denkbar, die mittels einer Mikrooptik entblendet sind. Eine solche Mikrooptik könnte direkt in die Glasplatte eingearbeitet sein.As a lamp, at least one fluorescent lamp can be used, which is preferably blinding by means of light grid in a known manner. Alternatively, as a light source also several Light-emitting diodes conceivable that are blended by means of a micro-optics. Such a micro-optic could be incorporated directly into the glass plate.
Die Erfindung sowie weitere vorteilhafte Ausführungen werden anhand der beigefügten Zeichnungen näher erläutert.The invention and further advantageous embodiments will be explained in more detail with reference to the accompanying drawings.
