Description

Die Erfindung betrifft eine Leuchte, insbesondere eine Leuchte für Beleuchtungszwecke im Außenbereich oder Innenbereich, z.B. eine Einbau- oder Anbauleuchte, welche ein Leuchtengehäuse und eine transparente Abdeckung zum Verschließen des Gehäuses aufweist.The invention relates to a luminaire, in particular a luminaire for outdoor or indoor lighting, e.g. a recessed or surface-mounted luminaire, which has a luminaire housing and a transparent cover for closing the housing.

Leuchten der eingangs genannten Art werden für verschiedene Anwendungszwecke vorgesehen und in größerer Stückzahl hergestellt. Abhängig von dem Einsatzzweck der Leuchte sind unterschiedliche Zusatzfunktionen, wie Lichtsensoren oder Bewegungsmelder zum Steuern der Leuchte oder Notlichtsysteme zum Anzeigen eines Fluchtweges etc. wünschenswert. Der Nachteil derartiger Leuchten besteht darin, dass sie jeweils nur für einen Einsatzzweck vorgesehen werden können bzw. die Produktion für einen bestimmten Einsatzzweck der Leuchte geändert werden muss.Lights of the type mentioned are intended for various applications and manufactured in larger quantities. Depending on the intended use of the luminaire, various additional functions, such as light sensors or motion detectors for controlling the luminaire or emergency lighting systems for indicating an escape route, etc., are desirable. The disadvantage of such lights is that they can be provided in each case only for one purpose or production must be changed for a particular purpose of the lamp.

Die Druckschrift WO 2010/116200 A1 offenbart eine Lampe mit einem Lampengehäuse und einer Lampenabdeckung. Ein passiver Infrarotsensor ist an einem Ende einer Röhre an der Lampenabdeckung montiert. Auf diese Weise wird der passive Infrarotsensor bis zu einer zusätzlichen Abdeckung einer Leuchte nach vorne geführt, während die Lampe an einer Position hinter der Abdeckung bleibt.The publication WO 2010/116200 A1 discloses a lamp having a lamp housing and a lamp cover. A passive infrared sensor is mounted on one end of a tube on the lamp cover. In this way, the passive infrared sensor is led forward to an additional cover of a lamp, while the lamp remains in a position behind the cover.

Die Druckschrift CN 2014 20982 Y offenbart eine LED-Leuchte gemäß dem Oberbegriff des Anspruchs 1, bei der ein Sensor auf dem Boden des Gehäuses montiert ist und sich durch eine Abdeckung erstreckt.The publication CN 2014 20982 Y discloses an LED lamp according to the preamble of claim 1, wherein a sensor is mounted on the bottom of the housing and extends through a cover.

Die Druckschrift CN 202144953 U offenbart eine Lampe mit einer Abdeckung, in welcher in einer runden Öffnung ein Linsenelement integriert ist. Unterhalb des Linsenelements ist ein optischer Sensor angeordnet.The publication CN 202144953 U discloses a lamp with a cover in which a lens element is integrated in a round opening. Below the lens element, an optical sensor is arranged.

Aufgabe der vorliegenden Erfindung ist es, eine Leuchte der eingangs genannten Art bereitzustellen, welche kostengünstig für eine Vielzahl von Einsatzzwecken modifiziert werden kann.Object of the present invention is to provide a luminaire of the type mentioned, which can be inexpensively modified for a variety of uses.

Die Aufgabe wird gelöst durch eine Leuchte, insbesondere eine Leuchte für Beleuchtungszwecke, die als Innenleuchte oder als Außenleuchte ausgebildet sein kann, z.B. eine Wannenleuchte, Einbau- oder Anbauleuchte, Pendelleuchte, Stehleuchte, Decken- oder Wandleuchte, nach Anspruch 1.The object is achieved by a lamp, in particular a lamp for lighting purposes, which can be designed as an interior light or as an outdoor lamp, e.g. a trough luminaire, recessed or surface-mounted luminaire, pendant luminaire, floor lamp, ceiling or wall luminaire, according to claim 1.

Die erfindungsgemäße Anordnung der Öffnung in der transparenten Abdeckung weist zahlreiche Vorteile auf, weil die transparente Abdeckung unabhängig von dem Einbauort der Leuchte immer in Richtung zu dem zu beleuchtenden Raumabschnitt ausgerichtet sein wird. Dadurch ist gewährleistet, dass der in der Öffnung angebrachte Sensor auch den interessierenden Raumabschnitt überwacht. Von besonderem Vorteil ist ferner, dass die Öffnung die Aufnahme wechselbarer elektrischer Einsätze erlaubt. Dadurch lassen sich Leuchten aus der gleichen Produktionsserie mit verhältnismäßig geringem Aufwand individuell für einen Einsatzzweck herrichten. Sofern kein elektronischer Einsatz gewünscht ist, kann die Öffnung mit einem Deckel oder einem transparenten Einsatz, der bevorzugt die Oberflächenstruktur der transparent Abdeckung fortsetzt, geschlossen werden.The arrangement according to the invention of the opening in the transparent cover has numerous advantages, because the transparent cover will always be oriented in the direction of the room section to be illuminated regardless of the installation location of the luminaire. This ensures that the sensor mounted in the opening also monitors the space of interest. Of particular advantage is further that the opening allows the inclusion of removable electrical inserts. This allows lights from the make the same production series with relatively little effort individually for a purpose. If no electronic use is desired, the opening can be closed with a lid or a transparent insert, which preferably continues the surface structure of the transparent cover.

Als wechselbare Einsätze sind insbesondere Bewegungsmelder, Helligkeitssensoren, Infrarotsensoren, Radarsensor, jeweils zur Steuerung der Leuchte oder einer ganzen Gruppe von Leuchten vorgesehen oder zur Überwachung eines Verkehrsraums. Ferner sind wechselbare Einsätze in Form eines Notlichts, insbesondere mit einem oder mehreren LEDs oder OLEDs als Leuchtmittel, bevorzugt. Das Notlicht kann insbesondere mit einer Optik ausgestattet sein, die eine längliche Lichtverteilung auf der zu beleuchtenden Fläche erzeugt, um z.B. einen Fluchtweg anzuzeigen, oder als Antipanikbeleuchtung.Motion detectors, brightness sensors, infrared sensors, radar sensors, in each case for controlling the luminaire or a whole group of luminaires, or for monitoring a traffic space are provided as interchangeable inserts. Furthermore, changeable inserts in the form of an emergency light, in particular with one or more LEDs or OLEDs as lighting means, are preferred. In particular, the emergency light may be provided with optics which produce an elongate light distribution on the surface to be illuminated, e.g. to indicate an escape route, or as anti-panic lighting.

Gemäß einer bevorzugten Ausführungsform ist an einem Rand der Abdeckung, welcher im montierten Zustand der Leuchte von dem Leuchtengehäuse verdeckt ist, wenigstens eine Einrichtung zum Befestigen der elektrischen Leitung integriert. Dadurch kann die elektrische Zuleitung zu dem wechselbaren elektrischen Einsatz innerhalb des Gehäuses geschützt verlegt werden, so dass die Leitung von außen durch die transparente Abdeckung nicht oder kaum sichtbar ist.According to a preferred embodiment, at least one device for fixing the electrical line is integrated on an edge of the cover, which is covered by the lamp housing in the mounted state of the lamp. As a result, the electrical supply line to the replaceable electrical insert can be laid protected within the housing, so that the line from the outside through the transparent cover is not or hardly visible.

Gemäß einer bevorzugten Ausführungsform ist die Einrichtung zur Aufnahme der elektrischen Leitung als Zugentlastung ausgebildet. Dies hat insbesondere den Vorteil, dass auf den wechselbaren elektrischen Einsatz über die elektrische Anschlussleitung keine Kraft ausgeübt wird, wenn die transparente Abdeckung zur Reinigungs- oder Wartungsarbeiten von der Leuchte abgenommen wird.According to a preferred embodiment, the device for receiving the electrical line is designed as a strain relief. This has the particular advantage that no force is exerted on the replaceable electrical insert via the electrical connection line when the transparent cover for cleaning or maintenance of the light is removed.

Gemäß einer bevorzugten Ausführungsform ist die Öffnung rechteckig ausgebildet. Die Rechteckform weist den Vorteil auf, dass gegenüberliegende Ränder der Öffnung zum Befestigen, insbesondere zum Festklemmen oder Einrasten, eines elektrischen Einsatzes genutzt werden können. Ferner ist im Vergleich zu einer runden Öffnung die räumliche Ausrichtung des wechselbaren elektrischen Einsatzes definiert. Dies ist insbesondere für Notlichter, welche eine definierte längliche Lichtverteilung erzeugen sollen, von Vorteil. Bevorzugte Größen für die Öffnung besitzen eine Länge zwischen 40 mm und 70 mm, insbesondere zwischen 50 mm und 60 mm, und eine Breite zwischen 10 mm und 30 mm, insbesondere zwischen 15 mm und 25 mm.According to a preferred embodiment, the opening is rectangular. The rectangular shape has the advantage that opposite edges of the opening for fastening, in particular for clamping or snapping, an electrical insert can be used. Furthermore, in comparison to a round opening, the spatial orientation of the exchangeable electrical insert is defined. This is particularly advantageous for emergency lights, which should produce a defined elongated light distribution. Preferred sizes for the opening have a length between 40 mm and 70 mm, in particular between 50 mm and 60 mm, and a width between 10 mm and 30 mm, in particular between 15 mm and 25 mm.

Kleinere Öffnungen wären zwar für Mikrosensoren möglich, sind jedoch aufgrund der Einschränkung, dass keine Notlichter oder dgl. gesetzt werden können, weniger bevorzugt.While smaller openings would be possible for microsensors, they are less preferred due to the limitation that emergency lights or the like can not be set.

Gemäß einer bevorzugten Ausführungsform ist die transparente Abdeckung aus einem Kunststoff gebildet. Kunststoff hat im Unterschied zum Glas den Vorteil, dass sich die Öffnung zur Aufnahme des wechselbaren elektrischen Einsatzes leichter ausbilden lässt. Insbesondere rechteckige Öffnungen sind in einer Glasabdeckung kaum zu realisieren, ohne dass eine erhebliche Bruchgefahr gegeben ist.According to a preferred embodiment, the transparent cover is formed from a plastic. In contrast to the glass, plastic has the advantage that the opening for receiving the exchangeable electrical insert can be formed more easily. In particular, rectangular openings are difficult to realize in a glass cover, without a significant risk of breakage is given.

Gemäß einer bevorzugten Ausführungsform ist zwischen der transparenten Abdeckung und dem Gehäuse eine flexible Montagehilfe befestigt, welche ein Abhängen der transparenten Abdeckung an dem Gehäuse im demontierten Zustand ermöglicht. Wenn zu Reinigungs- oder Wartungsarbeiten die transparente Abdeckung von dem Gehäuse abgenommen wird, kann diese an der flexiblen Montagehilfe frei im Raum aufgehängt werden. Diese Ausführungsform ist in Verbindung mit wechselbaren elektrischen Einsätzen besonders bevorzugt, weil beim Abnehmen der transparenten Abdeckung die Gefahr besteht, dass elektrische Zuleitungen zu dem wechselbaren elektrischen Einsatz abgerissen werden.According to a preferred embodiment, a flexible mounting aid is attached between the transparent cover and the housing, which allows a suspension of the transparent cover to the housing in the disassembled state. If the transparent cover is removed from the housing for cleaning or maintenance work, it can be hung freely on the flexible mounting aid in the room. This embodiment is particularly preferred in connection with interchangeable electrical inserts, because when removing the transparent cover there is the risk that electrical leads are torn off to the exchangeable electrical insert.

Gemäß einer bevorzugten Ausführungsform ist im montierten Zustand der Abdeckung die Montagehilfe entlang eines vom Gehäuse verdeckten Randes der Abdeckung eingefaltet. Die Montagehilfe bleibt dauerhaft zwischen der Abdeckung und dem Gehäuse befestigt. Ferner ist bei dieser Ausführungsform die Montagehilfe im montierten Zustand der Abdeckung von außen nicht sichtbar.According to a preferred embodiment, the mounting aid is folded along a concealed edge of the cover in the assembled state of the cover. The mounting aid remains permanently attached between the cover and the housing. Furthermore, in this embodiment, the mounting aid in the assembled state of the cover from the outside is not visible.

Gemäß einer bevorzugten Ausführungsform weist die Abdeckung, insbesondere an einem nach innen versetzten Rand, Haken auf, welche mit flexiblen Rastelementen, die an dem Gehäuse vorgesehen sind, zum Verschließen der Leuchte zusammenwirken. Beispielsweise kann an der Abdeckung ein starrer Haken mit einer Anlaufschräge und einer zurückspringenden Kante vorgesehen sein. Zum Montieren der Abdeckung wird durch die Anlaufschräge des Hakens ein flexibles Rastelement, welches mit dem Gehäuse verbunden ist, ausgelenkt. In der Montageposition rastet das flexible Rastelement hinter der zurückspringenden Kante ein und sichert damit die Abdeckung an dem Leuchtengehäuse.According to a preferred embodiment, the cover, in particular on an inwardly offset edge, hooks, which cooperate with flexible latching elements, which are provided on the housing, for closing the lamp. For example, may be provided on the cover a rigid hook with a run-on slope and a recessed edge. To mount the cover, a flexible locking element, which is connected to the housing, deflected by the run-on slope of the hook. In the Mounting position engages the flexible locking element behind the recessed edge and thus secures the cover to the lamp housing.

Der wechselbare elektrische Einsatz gemäß der vorliegenden Erfindung weist Rastmittel auf, welche an zwei gegenüberliegenden Rändern der Öffnung verrastet sind. Beispielsweise können die Rastmittel an den zwei Schmalseiten einer rechteckförmigen Öffnung in der Abdeckung verrastet sein.

Die Leuchten weisen ein Gehäuse 2 auf, welches nach unten mit einer transparenten oder wenigstens teilweise transparenten Abdeckung 4 geschlossen ist. Innerhalb der Abdeckung 4 ist ein elektrischer Einsatz 6 vorgesehen, welcher wie nachfolgend beschrieben wird, auswechselbar ist.The Figures 1 and 2 show two embodiments of the lamp according to the invention, wherein the embodiment according to FIG. 1 as ceiling recessed luminaire and the embodiment according to FIG. 2 is designed as a floor lamp. The luminaires have a housing 2, which is closed at the bottom with a transparent or at least partially transparent cover 4. Within the cover 4, an electrical insert 6 is provided, which is as described below, interchangeable.

Figur 3 zeigt einen Ausschnitt der transparenten Abdeckung 4 der Figur 1. In der Fläche der Abdeckung 4, welche die Lichtaustrittsöffnung der Leuchte verschließt, ist eine rechteckige Öffnung 8 enthalten. Diese Öffnung 8 dient zur Aufnahme des wechselbaren elektrischen Einsatzes 6. FIG. 3 shows a section of the transparent cover 4 of FIG. 1 , In the surface of the cover 4, which closes the light exit opening of the lamp, a rectangular opening 8 is included. This opening 8 is used to hold the removable electrical insert. 6

Ein beispielhafter Einsatz 6 ist in Figur 6 dargestellt. Der Einsatz 6 weist eine etwa rechteckige Grundplatte auf, die sich im montierten Zustand in die Außenseite der transparenten Platte integriert. Auf der Rückseite sind jeweils zwei an den gegenüberliegenden Schmalseiten des Rechtecks Federelemente 10 vorgesehen, welche zum Verrasten des wechselbaren Einsatzes 8 auf der Rückseite (d.h. der dem Leuchtmittel zugewandten Seite) der Abdeckung 4 dienen. Die Rastelemente 10 weisen ein etwa U-förmiges Profil auf, wobei ein Schenkel des U mit dem wechselbaren Einsatz verbunden ist und der andere Schenkel des U frei beweglich ist, so dass er nach dem Einführen des wechselbaren Einsatzes 6 in die Öffnung 8 auf der Rückseite der Abdeckung 4 einrasten kann. In alternativen Ausführungsformen kann auch ein elastisches Rastelement an der Abdeckung vorgesehen sein, in welches der Einsatz einrastet.An exemplary insert 6 is in FIG. 6 shown. The insert 6 has an approximately rectangular base plate, which integrates in the mounted state in the outside of the transparent plate. On the back of each two on the opposite narrow sides of the rectangle spring elements 10 are provided, which serve for locking the interchangeable insert 8 on the back (ie the side facing the light source) of the cover 4. The locking elements 10 have an approximately U-shaped profile, one leg of the U is connected to the removable insert and the other leg of the U is free to move, so that he after insertion of the removable insert 6 in the opening 8 on the back the cover 4 can engage. In alternative embodiments, an elastic locking element may be provided on the cover into which the insert engages.

Der wechselbare elektrische Einsatz 6 gemäß Figur 6 ist als Notlichtsystem ausgebildet. Er weist als Leuchtmittel eine LED auf, die mit einer refraktiven Optik 12 abgedeckt ist. Die Optik 12 sorgt für eine längliche Lichtverteilung, wie sie in den Figuren 7a und 7b dargestellt ist. In Figur 7a ist die Lichtverteilungskurve in einem horizontalen Schnitt durch die Leuchte in Polarkoordinaten dargestellt. Man erkennt eine symmetrische Lichtverteilung mit zwei Hauptmaxima bei einem Winkel von etwa ±60° gegenüber dem Lot durch die Leuchte. Die Lichtverteilung auf der zu beleuchtenden Fläche ist in Figur 7b dargestellt. Anhand der Höhenlinien, welche jeweils eine Linie konstanter Beleuchtungsstärke darstellen, ist zu erkennen, dass die Lichtverteilung längs verteilt ist. Die Lichtverteilung wird z.B. genutzt, um die Richtung eines Fluchtweges anzuzeigen und diesen zu beleuchten. Das Notlicht kann auch nur als Antipanikbeleuchtung dienen, z.B. mit einer runden oder rechteckigen Lichtverteilung, um den Raum mit einer für Notfälle ausreichenden Beleuchtungsstärke auszuleuchten.The replaceable electrical insert 6 according to FIG. 6 is designed as an emergency lighting system. It has an LED as a light source, which is covered with a refractive optics 12. The optic 12 provides an elongated light distribution, as in the FIGS. 7a and 7b is shown. In Figure 7a the light distribution curve is shown in a horizontal section through the luminaire in polar coordinates. One recognizes a symmetrical light distribution with two main maxima at an angle of about ± 60 ° with respect to the solder through the luminaire. The light distribution on the surface to be illuminated is in FIG. 7b shown. Based on the contour lines, which each represent a line of constant illuminance, it can be seen that the light distribution is distributed longitudinally. The light distribution is used, for example, to indicate the direction of an escape route and to illuminate it. The emergency light can also serve only as anti-panic lighting, eg with a round or rectangular light distribution, to illuminate the room with an illuminance sufficient for emergencies.

Weitere Ausführungsformen von wechselbaren elektrischen Einsätzen, die in den Figuren nicht dargestellt sind, umfassen Lichtstärkesensoren, um z. B. abhängig von der Umgebungshelligkeit ein automatisches Ein- und Ausschalten der Leuchte zu steuern. Weitere Beispiele sind Bewegungsmelder, die ebenfalls zum Steuern von einer oder mehreren Leuchten verwendet werden.Other embodiments of interchangeable electrical inserts, which are not shown in the figures, include luminous intensity sensors, for. B. depending on the ambient brightness to control automatic switching on and off the lamp. Other examples are motion detectors, which are also used to control one or more lights.

Bezug nehmend auf Figur 3 ist zu erkennen, dass die Öffnung 8 nahe des Randes der Abdeckung 4 angeordnet ist. Die elektrischen Zuleitungskabel für den wechselbaren elektrischen Einsatz 6 können von der Öffnung 8 direkt zum Rand gelegt werden und dort entlang des Randes auf der Innenseite der Abdeckung 4 verlegt werden. Dazu sind Befestigungselemente entlang des Randes der Abdeckung 4 vorgesehen. In der gezeigten Ausführungsform ist insbesondere eine Lasche 14 und eine Öse 16 dargestellt. Das Abschlusskabel kann zwischen der Lasche 14 und der Öse 16 geführt werden und mittels eines Kabelbinders an der Öse 16 befestigt werden. Bevorzugt ist, dass die Aufnahmemittel 14, 16 für die elektrische Zuleitung auch als Zugentlastung für die elektrische Zuleitung wirken, so dass bei Ausüben einer Kraft auf die elektrische Leitung, z.B. beim Abnehmen der transparenten Abdeckung 4 vom Gehäuse 2, die Kraft nicht auf den auswechselbaren elektrischen Einsatz 6 übertragen wird.Referring to FIG. 3 It can be seen that the opening 8 is arranged near the edge of the cover 4. The electrical supply cable for the removable electrical insert 6 can be placed directly from the opening 8 to the edge and laid there along the edge on the inside of the cover 4. For this purpose, fastening elements along the edge of the cover 4 are provided. In the embodiment shown, in particular a tab 14 and an eyelet 16 are shown. The termination cable can be passed between the tab 14 and the eyelet 16 and secured to the eyelet 16 by a cable tie. It is preferred that the receiving means 14, 16 for the electrical supply also act as a strain relief for the electrical supply, so that when exerting a force on the electrical line, eg when removing the transparent cover 4 from the housing 2, the force is not on the interchangeable electrical insert 6 is transmitted.

Die Figuren 4 und 5 stellen jeweils den gleichen Ausschnitt eines Randbereichs der Abdeckung 4 dar. In Figur 5 ist ferner eine Montagehilfe 18 an der Abdeckung 4 dargestellt. Die Montagehilfe 18 ist aus einem flexiblen Kunststoff hergestellt und umfasst einen länglichen Schaft, der an seinen gegenüberliegenden Enden jeweils einen doppelhakenförmigen Vorsprung aufweist, der an einer Seite an der Abdeckung 4 in einer Öse 20 eingehakt werden kann und auf der gegenüberliegenden Seite am Gehäuse 2 in eine Öse (nicht dargestellt in den Figuren) eingehakt werden kann. Die Montagehilfe 18 dient dazu, die Abdeckung 4 im demontierten Zustand an dem Gehäuse frei hängend befestigen zu können, um z.B. Arbeiten an der Elektrik der Leuchte oder einen wechselbaren elektrischen Einsatz 6 vorzunehmen. Zum Montieren der Abdeckung 4 an dem Gehäuse 2 kann die Montagehilfe in der Leuchte verbleiben, weil sie sich entlang des Randes zwischen dem Gehäuse und der Abdeckung 4 einfaltet.The FIGS. 4 and 5 each represent the same section of an edge region of the cover 4. In FIG. 5 Furthermore, an assembly aid 18 is shown on the cover 4. The mounting aid 18 is made of a flexible plastic and comprises an elongated shaft which has at its opposite ends in each case a double hook-shaped projection which can be hooked on one side to the cover 4 in an eyelet 20 and on the opposite side of the housing 2 in an eyelet (not shown in the figures) can be hooked. The mounting aid 18 serves to be able to attach the cover 4 in the disassembled state to the housing freely suspended, for example, to perform work on the electrical system of the lamp or a removable electrical insert 6. For mounting the cover 4 to the housing 2, the mounting aid may remain in the lamp because it folds along the edge between the housing and the cover 4.

Ferner ist in den Figuren 4 und 5 ein Haken 22 am Rand der Abdeckung 4 dargestellt, der zum Befestigen der Abdeckung in dem Gehäuse dient. Der Haken weist eine Anlaufschräge in Richtung zum Gehäuse auf und einen zurückspringenden Rand. Der Haken 22 wirkt mit einem elastischen Rastelement (in den Figuren nicht dargestellt) an dem Gehäuse zusammen, welches durch die Anlaufschräge ausgelenkt wird und hinter der Kante einrastet.Furthermore, in the FIGS. 4 and 5 a hook 22 is shown at the edge of the cover 4, which serves to secure the cover in the housing. The hook has a run-up slope towards the housing and a recessed edge. The hook 22 cooperates with an elastic latching element (not shown in the figures) on the housing, which is deflected by the run-on slope and engages behind the edge.

Weitere Varianten der bevorzugten Ausführungsform sind im Rahmen der Erfindung, wie sie in den Ansprüchen definiert ist, möglich. Insbesondere eignet sich das Konzept einer Öffnung in der Abdeckung einer Leuchte für beliebige Ausführungsformen von Leuchten. Bevorzugt werden immer gleiche Öffnungen, z.B. die dargestellten rechteckigen Öffnungen, verwendet, um die gleichen wechselbaren elektrischen Einsätze für unterschiedliche Leuchten verwenden zu können.Further variants of the preferred embodiment are possible within the scope of the invention as defined in the claims. In particular, the concept of opening in the cover of a lamp for any embodiments of lights is suitable. Preferably, always the same openings, for example, the illustrated rectangular openings, used to use the same exchangeable electrical inserts for different lights can.
