Description

Die Erfindung betrifft eine Notleuchte zum Verbau in einer Wand, Decke oder ähnlichem, bei der Leuchtmittel zur Anzeige des Ladezustandes von, in der Leuchte befindlichen Batterien oder Akkumulatoren vorgesehen ist, wobei die Batterien oder Akkumulatoren in der Lage sind Lichtquellen zur Beleuchtung einer Anzeigevorrichtung im Falle eines Stromausfalls mit Strom zu versorgen.The invention relates to an emergency luminaire for installation in a wall, ceiling or the like, is provided in the lighting means for displaying the state of charge of, located in the luminaire batteries or accumulators, the batteries or accumulators are capable of light sources for illuminating a display device in the case to power a power failure.

Eine Notleuchte weist zumeist auf einen Flucht- bzw. Rettungsweg hin und wird daher auch als Hinweis- Fluchtwegs- oder Rettungszeichenleuchte bezeichnet. Bei diesen Notleuchten ist ein be- bzw. hinterleuchtetes Piktogramm vorgesehen, welches eine entsprechende Information vermitteln soll. Herkömmlicherweise findet die Hinterleuchtung eines Piktogramms, welches sich an einer lichtdurchlässigen Abdeckung eines Leuchtengehäuses befindet, mittels einer im Inneren des Leuchtengehäuses angeordneten Lampe oder Leuchtstoffröhre statt.An emergency light usually points to an escape or rescue route and is therefore also referred to as a notice escape route or escape sign light. In these emergency lights a backlit or backlit pictogram is provided, which should convey appropriate information. Conventionally, the backlighting of a pictogram, which is located on a translucent cover of a lamp housing, takes place by means of a lamp housing arranged inside the lamp or fluorescent tube.

Durch den Einzug der LED (Lichtemittierende Diode) in den Beleuchtungssektor ergeben sich vielfach neue Gestaltungsmöglichkeiten für Leuchten. Beispielsweise ist die Verwendung von LEDs, die Licht kantenseitig in eine Lichtleiterplatte einkoppeln, wobei dieses an einer Flachseite des Lichtleiters wiederausgekoppelt wird, inzwischen weit verbreitet und kommt in den verschiedensten Beleuchtungssituationen zum Einsatz, auch zur Hinterleuchtung von Piktogrammen, wie beispielsweise in der DE 20 2009 001 048 U1 beschieben.The introduction of the LED (light-emitting diode) into the lighting sector often results in new design options for luminaires. For example, the use of LEDs, the light edge coupled into a light guide plate, this being decoupled on a flat side of the light guide, now widely used and is used in a variety of lighting situations, including the backlighting of pictograms, such as in the DE 20 2009 001 048 U1 beschieben.

Eine Anwendung einer solchen Anzeigevorrichtung mit Lichtleiter ist beispielsweise als Display einer Notleuchte, die zum Verbau in einer Wand, Decke oder ähnlichem vorgesehen ist. Bei solchen Leuchten ist ein wannenartig ausgeführtes Leuchtengehäuse, zur Aufnahme von Steuerungs- und Versorgungsmitteln für die Lichtquellen, vorgesehen, welches in eine Vertiefung in einer Wand oder Decke eingelassen wird und im Wesentlichen bündig mit diesem abschließt. Auch kann an dem Leuchtengehäuse eine Gehäuserahmen vorgesehen sein, welcher über den Umfang der Gehäusewanne hinausragt, um so ein Hineinrutschen des Leuchtengehäuses in die Vertiefung zu vermeiden.An application of such a display device with light guide, for example, as a display of an emergency light, which is intended to be installed in a wall, ceiling or the like. In such Lights is a trough-like designed light housing, for receiving control and supply means for the light sources, provided, which is embedded in a recess in a wall or ceiling and substantially flush with this. Also, a housing frame may be provided on the lamp housing, which protrudes beyond the circumference of the housing pan, so as to prevent slipping in of the lamp housing into the recess.

Die Anzeigevorrichtung, also das mit Hilfe eines Lichtleiters hinterleuchtete Piktogramm, ist bei einer solchen zum Einbau vorgesehenen Ausführung einer Notleuchte üblicherweise vorne an dem Leuchtengehäuse befestigt und überdeckt dieses vollständig, so dass das Gehäuse für den Betrachter nicht mehr sichtbar ist.The display device, that is the backlit by means of a light guide pictogram, is usually attached to the front of the luminaire housing in such an intended for installation execution of an emergency light and covers it completely, so that the housing is no longer visible to the viewer.

Auch sind bei Notleuchten so genannte Statusanzeigen vorgesehen, nämlich Leuchtmittel die Auskunft über den Ladezustand der, in dem Leuchtengehäuse angeordneten, Batterien oder Akkumulatoren geben, welche im Falle eines Stromausfalls die Lichtquellen der Anzeigevorrichtung weiterhin mit Strom versorgen. Leuchtmittel dieser Art sind meist im Gehäuse einer Notleuchte angebracht, so dass sie sicher und störunanfällig mit den Batterien oder Akkumulatoren in Verbindung stehen. Eine derartige Status-LED ist beispielsweise in der DE 101 23 006 A1 gezeigt, wobei die LED hier in an der Stirnseite eines Profilteils angeordnet ist, der die eigentliche Anzeigevorrichtung der Leuchte trägt. Eine vergleichbare Lösung ist auch aus der US 6,294,983 B1 bekannt.Also, so-called status indicators are provided in emergency lights, namely bulbs provide information about the state of charge of, arranged in the lamp housing, batteries or accumulators, which continue to supply the light sources of the display device in case of power failure, the power. Lamps of this type are usually mounted in the housing of an emergency light, so that they are safe and trouble-free with the batteries or accumulators in combination. Such a status LED is for example in the DE 101 23 006 A1 shown, wherein the LED is arranged here in on the front side of a profile part, which carries the actual display device of the lamp. A comparable solution is also from the US 6,294,983 B1 known.

Ist nun die Leuchte so ausgeführt, dass das Leuchtengehäuse in einer Wand oder Decke versenkt und mit einer Anzeigevorrichtung überdeckt wird, ist dieses Leuchtengehäuse und folglich auch ein Leuchtmittel zur Ladezustandsanzeige, welches sich innerhalb des Leuchtengehäuses befindet, oder Licht, welches von einem solchen Leuchtmittel abgegeben wird, für einen Betrachter nicht sichtbar.Now, if the lamp is designed so that the luminaire housing is sunk in a wall or ceiling and covered with a display device, this luminaire housing and consequently also a bulb for charging status indicator, which is located within the lamp housing, or light, which emitted from such a bulb becomes invisible to a viewer.

Der vorliegenden Erfindung liegt daher die Aufgabe zu Grunde, eine Ausführung einer Notleuchte mit oben beschriebenem Aufbau vorzuschlagen, bei welcher ein, von einem Leuchtmittel zur Ladezustandsanzeige abgegebenes Licht für einen Betrachter sichtbar ist.The present invention is therefore based on the object to propose an embodiment of an emergency light with the above-described structure, in which a, emitted by a light source for state of charge display light is visible to a viewer.

Die Aufgabe wird durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der abhängigen Ansprüche. Hierbei ist in dem Leuchtengehäuse eine Lichtaustrittsöffnung vorgesehen und ein zur Ladezustandsanzeige vorgesehenes Leuchtmittel der Lichtaustrittsöffnung so zugeordnet, dass das von dem Leuchtmittel abgestrahlte Licht außerhalb des Leuchtengehäuses sichtbar ist.The object is solved by the characterizing features of claim 1. Advantageous developments of the invention are the subject of the dependent claims. In this case, a light exit opening is provided in the luminaire housing, and a light means provided for charging state indication is assigned to the light exit opening such that the light emitted by the illuminant is visible outside the luminaire housing.

Erfindungsgemäß wird also eine Notleuchte zum Verbau in einer Wand vorgeschlagen, welche aufweist:

  • eine Anzeigevorrichtung, wobei die Anzeigevorrichtung eine Lichtleiterplatte und dieser zugeordnete Lichtquellen aufweist,
  • ein wannenförmiges Leuchtengehäuse zur Aufnahme von Mitteln zur Versorgung und zum Betreiben der Lichtquellen der Anzeigevorrichtung, wobei das Leuchtengehäuse zum Einbau in einer Vertiefung in einer Wand vorgesehen ist und einen Gehäuserahmen aufweist, und wobei die Anzeigevorrichtung den Gehäuserahmen vollständig überdeckt und derart an dem Leuchtengehäuse oder dem Gehäuserahmen befestigt ist, dass im eingebauten Zustand der Notleuchte zwischen der Anzeigevorrichtung und der Wand ein Spalt besteht,
  • ein Leuchtmittel zur Anzeige des Ladezustandes von in dem Leuchtengehäuse befindlichen Batterien oder Akkumulatoren, die zur Versorgung der Lichtquellen der Anzeigevorrichtung im Notfall geeignet sind,
wobei das Leuchtmittel innerhalb des Leuchtengehäuses angeordnet ist, und wobei in dem Gehäuserahmen eine Lichtaustrittsöffnung vorgesehen ist und das Leuchtmittel der Lichtaustrittsöffnung so zugeordnet ist, dass das von dem Leuchtmittel abgestrahlte Licht die Lichtaustrittsöffnung durchtritt und auf der Wand einen Leuchtkegel projektiert, so dass es außerhalb des Leuchtengehäuses sichtbar istAccording to the invention, therefore, an emergency luminaire for installation in a wall is proposed, which comprises:
  • a display device, the display device having a light guide plate and associated light sources,
  • a trough-shaped luminaire housing for receiving means for supplying and operating the light sources of the display device, wherein the luminaire housing is provided for installation in a recess in a wall and has a housing frame, and wherein the display device completely covers the housing frame and so on the luminaire housing or the Housing frame is fixed, that in the installed state of the emergency light between the display device and the wall is a gap,
  • a luminous means for displaying the state of charge of batteries or accumulators located in the luminaire housing, which are suitable for supplying the light sources of the display device in an emergency,
wherein the lighting means is disposed within the lamp housing, and wherein in the housing frame, a light exit opening is provided and the lighting means of the light exit opening so it is associated with the light emitted by the illuminant passing through the light exit opening and projecting a luminous cone on the wall, so that it is visible outside the luminaire housing

Der Gehäuserahmen ragt über den Querschnitt des Leuchtengehäuses hinaus und liegt im eingebauten Zustand auf der Wand auf. So ist sichergestellt, dass die Lichtaustrittsöffnung außerhalb der Einbauvertiefung liegt und Licht, welches von dem Leuchtmittel abgegeben wird und durch die Lichtaustrittsöffnung tritt, außerhalb des Leuchtengehäuses auch in eingebautem Zustand jedenfalls sichtbar ist.The housing frame protrudes beyond the cross section of the luminaire housing and is in the installed state on the wall. This ensures that the light exit opening lies outside the installation recess and that light which is emitted by the luminous means and passes through the light exit opening is in any case visible outside the luminaire housing, even when installed.

Im eingebauten Zustand besteht zwischen der Anzeigevorrichtung und der Wand, in welcher die Notleuchte verbaut ist, also ein Abstand von vorzugsweise einem bis mehreren Millimetern. Die Anzeigevorrichtung liegt damit nicht auf der Wand auf, sondern zwischen Wand und Anzeigevorrichtung bildet sich ein Spalt. So ist sichergestellt, dass das vom Leuchtmittel ausgesendete Licht nicht von der Anzeigevorrichtung blockiert wird, und damit für einen Betrachter unsichtbar ist. Der Abstand von der Anzeigevorrichtung zur Wand ist optimalerweise eher gering, insbesondere im Vergleich zur Tiefe der Anzeigevorrichtung, um so den Aufbau der Notleuchte stabil und sicher zu belassen.When installed, there is between the display device and the wall in which the emergency light is installed, so a distance of preferably one to several millimeters. The display device is thus not on the wall, but between wall and display device forms a gap. This ensures that the light emitted by the light source is not blocked by the display device and thus is invisible to a viewer. The distance from the display device to the wall is optimally rather small, in particular compared to the depth of the display device so as to leave the structure of the emergency light stable and secure.

Ist das Leuchtmittel als LED ausgebildet, ist eine besonders kompakte Anordnung möglich. Wenn diese LED weiterhin in der Lage ist farbiges und besonders bevorzugt grünes Licht abzugeben, so ist die Projektion dieses Lichts auf einer, üblicherweise weißen Wand, besonders deutlich erkennbar.If the light source is designed as an LED, a particularly compact arrangement is possible. If this LED is furthermore able to emit colored and particularly preferred green light, then the projection of this light on a, usually white wall, is particularly clearly recognizable.

Dadurch, dass das Leuchtmittel beabstandet von der Lichtaustrittsöffnung angeordnet ist, ist die Störanfälligkeit des Leuchtmittels durch äußere Einflüsse deutlich verringert. Wird das Leuchtmittel weiterhin mittels einer Haltevorrichtung in dem Leuchtengehäuse positioniert, ist die Montage des Leuchtmittels innerhalb des Leuchtengehäuses deutlich vereinfacht. Zur weiteren Vereinfachung der Montage des Leuchtmittels in dem Leuchtengehäuse kann an der Haltevorrichtung eine Positionierungsnoppe vorgesehen sein, die dazu vorgesehen ist, mit einem entsprechenden Gegenelement in dem Leuchtengehäuse zu korrespondieren und somit eine präzise Ausrichtung der Haltevorrichtung und des Leuchtmittels zu ermöglichen.Due to the fact that the luminous means is arranged at a distance from the light exit opening, the susceptibility of the luminous means to interference is markedly reduced by external influences. If the lamp is further positioned by means of a holding device in the luminaire housing, the mounting of the Bulb clearly simplified within the lamp housing. To further simplify the mounting of the luminous means in the luminaire housing, a positioning nub may be provided on the holding device, which is intended to correspond to a corresponding counter element in the luminaire housing and thus to enable precise alignment of the holding device and the luminous means.

Vorteilhaft ist die Befestigung der Haltevorrichtung in dem Leuchtengehäuse mittels Verschraubung, Verschweißung oder Vernietung realisiert, um so eine Positionsänderung des Leuchtmittels relativ zu der Lichtaustrittsöffnung zu vermeiden.Advantageously, the attachment of the holding device is realized in the lamp housing by means of screwing, welding or riveting, so as to avoid a change in position of the illuminant relative to the light exit opening.

Weiterhin ist in einer Ausbildung der Notleuchte bevorzugt, dass das Leuchtengehäuse eine Montagerichtungsangabe aufweist, welche die vorgesehene Orientierung der Leuchte für den Einbau in eine Wand angibt. Die Lichtaustrittsöffnung ist entsprechend der Montagerichtungsangabe an der zum Boden orientierten Seite des Gehäuserahmens positioniert. Durch eine derartige Positionierung des Leuchtmittels kann die Sichtbarkeit des projektierten Leuchtkegels auch dann gewährleistet werden, wenn die Notleuchte über der Augenhöhe des Betrachters befindlich ist.Furthermore, in an embodiment of the emergency light, it is preferred that the luminaire housing has a mounting direction indication which indicates the intended orientation of the luminaire for installation in a wall. The light exit opening is positioned according to the assembly direction indication on the floor-oriented side of the housing frame. By such positioning of the light source, the visibility of the projected light cone can be ensured even if the emergency light is located above the eye level of the viewer.

Die Erfindung wird anhand eines Ausführungsbeispiels gemäß den Zeichnungen näher erläutert, wobei

  • Fig. 1 eine perspektivische Rückansicht einer erfindungsgemäßen Notleuchte zeigt. Dargestellt ist ein wannenförmiges Leuchtengehäuse 1 mit einem Gehäuserahmen 2, wobei die Öffnung des wannenförmigen Leuchtengehäuses 1 mittels einer Anzeigevorrichtung 3 verschlossen ist. Das Leuchtengehäuse 1 nimmt die zum Betreiben der Anzeigevorrichtung 3 nötigen elektronischen Bauteile auf und ist zum Einbau in eine entsprechende Vertiefung in einer Wand, Decke oder dergleichen vorgesehen. Das wannenförmige Leuchtengehäuse 1 weist weiterhin einen Gehäuserahmen 2 auf, der über den Querschnitt des Leuchtengehäuses 1 hinausragt, somit ein Verrutschen der Leuchte in die Vertiefung hinein verhindert und eine Auflagefläche für die Anzeigevorrichtung 3 bereitstellt. Hierbei ist weiterhin vorgesehen, dass der untere, dem Leuchtengehäuse 1 zugewandte Rand des Gehäuserahmens 2, in eingebautem Zustand bündig mit der Wand oder Decke abschließt und so ein Hineinrutschen des Leuchtengehäuses 1 in die Vertiefung verhindert. Die an dem Leuchtengehäuse 1 befestigte Anzeigevorrichtung 3, in Form einer Lichtleiterplattenbeleuchtung, überdeckt den Gehäuserahmen 2 vollständig, wodurch, in eingebautem Zustand nur die Anzeigevorrichtung der Notleuchte sichtbar ist, was optisch besonders ansprechend ist. Bei einer solchen Ausführungsform besteht das Problem, dass in oder am Leuchtengehäuse 1 vorgesehene Leuchtmittel 5, zur Anzeige des Ladezustandes von Batterien oder Akkumulatoren für einen Betrachter nicht mehr sichtbar sind. Daher ist im Gehäuserahmen 2 eine Lichtaustrittsöffnung 4 vorgesehen, der ein im Leuchtengehäuse 1 vorgesehenes Leuchtmittel 5 zugeordnet ist, wobei Licht, welches von dem Leuchtmittel 5 abgegeben wird durch die Lichtaustrittsöffnung 4 nach außen tritt.
  • Fig. 2 zeigt eine perspektivische Vorder- bzw. Innenansicht eines Leuchtengehäuses 1 einer erfindungsgemäßen Notleuchte, hier ohne Anzeigevorrichtung 3 dargestellt, wobei das Leuchtmittel 5 mit Hilfe einer Haltevorrichtung 6 beabstandet zu der Lichtaustrittsöffnung 4 positioniert ist. Dabei sitzt das Leuchtmittel 5 in einer Durchführungsöffnung der im Wesentlichen stufenförmigen ausgebildeten Haltevorrichtung 6, wobei sich die Durchführungsöffnung in einem ersten Abschnitt der Haltevorrichtung 6 befindet, die von einem zweiten Abschnitt, der zur Befestigung der Haltevorrichtung 6 an dem Leuchtengehäuse 1 ausgebildet ist, durch einen Verbindungsabschnitt beabstandet verbunden ist.
  • In Fig. 3 ist eine Vorderansicht eines erfindungsgemäßen Leuchtengehäuses.1, mit Lichtaustrittsöffnung 4, Leuchtmittel 5 und Haltevorrichtung 6 dargestellt. Weiterhin ist dargestellt, dass Licht, welches von dem Leuchtmittel 5 abgegeben wird, die Lichtaustrittsöffnung 4 durchtritt und dieses Licht, auf einer Wand oder einer Decke einen Leuchtkegel 8 projektiert. Üblicherweise ist an Einbauleuchten eine Montagerichtungsanzeige 9 vorgesehen, die angibt welche Orientierung die Leuchte in eingebautem Zustand haben soll. Zweckmäßigerweise ist die Lichtaustrittsöffnung 4 an der zum Boden orientierten Seite des Gehäuserahmens 2 angeordnet, also an der Seite, die sich bei ordnungsgemäßem Einbau, entsprechend der Vorgabe durch die Montagerichtungsangabe 9, unten befindet. So ist auch bei über Augenhöhe montierten Notleuchten gewährleistet, dass der Leuchtkegel 8 für einen Betrachter sichtbar ist.
The invention will be explained in more detail with reference to an embodiment according to the drawings, wherein
  • Fig. 1 shows a rear perspective view of an emergency light according to the invention. Shown is a trough-shaped luminaire housing 1 with a housing frame 2, wherein the opening of the trough-shaped luminaire housing 1 is closed by means of a display device 3. The luminaire housing 1 accommodates the electronic components required for operating the display device 3 and is provided for installation in a corresponding recess in a wall, ceiling or the like. The trough-shaped luminaire housing 1 furthermore has a housing frame 2, which projects beyond the cross section of the luminaire housing 1, thus preventing slippage of the luminaire into the recess and providing a bearing surface for the display device 3. In this case, it is further provided that the lower, the lamp housing 1 facing edge of the housing frame 2, in the installed state flush with the wall or ceiling and thus prevents slipping in of the lamp housing 1 in the recess. The attached to the lamp housing 1 display device 3, in the form of a light guide plate illumination, completely covers the housing frame 2, whereby, in the installed state, only the display device of the emergency light is visible, which is visually particularly appealing. In such an embodiment, there is the problem that provided in or on the lamp housing 1 bulbs 5, for displaying the state of charge of batteries or accumulators are no longer visible to a viewer. Therefore, a light exit opening 4 is provided in the housing frame 2, which is assigned a provided in the lamp housing 1 illuminant 5, wherein light which is emitted from the lamp 5 passes through the light exit opening 4 to the outside.
  • Fig. 2 shows a perspective front and interior view of a lamp housing 1 of an emergency light according to the invention, shown here without display device 3, wherein the lighting means 5 by means of a holding device 6 is positioned at a distance from the light exit opening 4. In this case, the lamp 5 is seated in a passage opening of the substantially stepped-shaped holding device 6, wherein the lead-through opening is located in a first portion of the holding device 6, which is formed by a second portion which is adapted to attach the holding device 6 to the lamp housing 1 by a Connecting portion is connected at a distance.
  • In Fig. 3 is a front view of a lamp housing according to the invention.1, with light exit opening 4, 5 and 5 holding device shown. Furthermore, it is shown that light which is emitted by the luminous means 5 passes through the light exit opening 4 and projects this light onto a luminous cone 8 on a wall or a ceiling. Usually, a mounting direction indicator 9 is provided on recessed lights, indicating which orientation the light should have in the installed state. Conveniently, the light exit opening 4 is arranged on the bottom-oriented side of the housing frame 2, ie on the side, which is in proper installation, according to the specification by the mounting direction indicator 9, below. So even when mounted above eye level emergency lights ensures that the light cone 8 is visible to a viewer.
