Description

Die Erfindung betrifft eine Beleuchtungsvorrichtung mit einem Gehäuse enthaltend einen Basiskörper, nach dem Oberbegriff des Patentanspruches 1.The invention relates to a lighting device with a housing containing a base body, according to the preamble of claim 1.

Aus der EP 1 852 648 A1 ist eine Beleuchtungsvorrichtung bekannt, die als eine LED-Röhre ausgebildet ist. Hierzu weist die Beleuchtungsvorrichtung ein röhrenförmiges Gehäuse auf. Das Gehäuse weist einen langgestrecken Basiskörper auf, der endseitig durch mit Kontaktierungsstiften versehenen Endkappen abgeschlossen ist. Innerhalb des Gehäuses ist eine Mehrzahl von LED-Lichtquellen auf einer gemeinsamen Leiterplatte angeordnet. Der Basiskörper weist einen lichtdurchlässigen Umfangsabschnitt auf, durch den das von den LED-Lichtquellen abgestrahlte Lichtbündel in einem vorgegebenen Umfangswinkelbereich quer zu einer Längsachse des Gehäuses abgestrahlt wird. Die bekannte Beleuchtungsvorrichtung wird als Ersatz für herkömmliche Leuchtstofflampen verwendet, wobei das Gehäuse unter Kontaktierung der Kontaktstifte in herkömmliche, für Leuchtstofflampen vorgesehene Fassungen eingesetzt wird. Aufgrund des begrenzten Umfangswinkelbereiches (Lichtkegel) des abgestrahlten Lichtbündels, kann das Licht immer nur in einem festgelegten Winkelbereich von beispielsweise 120° in einer Querebene des Gehäuses abgestrahlt werden. Es ist jedoch wünschenswert, den Umfangswinkelbereich bezogen auf eine Einbaulage der Beleuchtungsvorrichtung zu variieren, um eine gezielte Ausleuchtung eines Raumes herbeizuführen.From the EP 1 852 648 A1 For example, a lighting device is known which is designed as an LED tube. For this purpose, the lighting device has a tubular housing. The housing has an elongated base body which is closed at the end by end caps provided with contacting pins. Within the housing, a plurality of LED light sources is arranged on a common printed circuit board. The base body has a translucent peripheral portion, through which the light beam emitted by the LED light sources is radiated in a predetermined circumferential angle range transversely to a longitudinal axis of the housing. The known lighting device is used as a replacement for conventional fluorescent lamps, wherein the housing is used by contacting the contact pins in conventional, provided for fluorescent lamps sockets. by virtue of the limited circumferential angle range (light cone) of the emitted light beam, the light can be emitted only in a predetermined angular range, for example, 120 ° in a transverse plane of the housing. However, it is desirable to vary the circumferential angle range with respect to a mounting position of the lighting device in order to bring about a targeted illumination of a room.

Aus der WO 2011/121145 A1 ist eine Beleuchtungsvorrichtung mit einem LED-Lichtquellen enthaltenden Gehäuse und einer stirnseitig angeordneten Rasteinrichtung zur drehbaren Verstellung einer mit Kontaktstiften versehenen Endkappe relativ zu dem Gehäuse bekannt. Die Endkappe wirkt jedoch mit einem Rastring zusammen, der zum einen fest mit dem Gehäuse verbunden ist und der zum anderen innenseitig eine Verzahnung aufweist. Der Rastring weist an einer radialen Stirnseite eine Skalierung auf, so dass eine Drehwinkelverstellung angezeigt wird.From the WO 2011/121145 A1 is a lighting device with a housing containing LED light sources and a frontally arranged latching device for rotatably adjusting a contact pins provided with the end cap relative to the housing known. However, the end cap cooperates with a locking ring which is connected to a fixed to the housing and on the other side has a toothing on the other. The locking ring has a scale on a radial end side, so that a rotation angle adjustment is displayed.

Aus der US 2010/0219739 A1 ist eine Beleuchtungsvorrichtüng mit einem LED-Lichtquellenaufweisenden Gehäuse sowie einer Rasteinrichtung bekannt, mittels derer stirnseitig des Gehäuses angeordnete Endkappen um einen frei wählbaren Verstelldrehwinkel um eine Längsachse des Gehäuses verstellbar ist. Diese Rasteinrichtung umfasst einen fest mit dem Gehäuse verbundene Rastscheibe sowie eine verdrehbar zu der Rastscheibe angeordnete Endkappe. Nachteilig an der bekannten Beleuchtungsvorrichtung ist, dass die Rastscheibe 12 und die Endkappe von einem gemeinsamen Gehäuse umgeben sein muss, wobei das Gehäuse über Befestigungsmittel fest mit der Rastscheibe verbunden ist. Das Gehäuse weist auch einen Abschlussflansch auf, an dem die Endkappe mittels einer Feder gespannt gehalten ist.From the US 2010/0219739 A1 is a Beleuchtungsvorrichtüng with a LED light sources having housing and a locking device known by means of which the front side of the housing arranged end caps is adjustable about a freely selectable Verstelldrehwinkel about a longitudinal axis of the housing. This latching device comprises a latching disc fixedly connected to the housing and an end cap arranged to be rotatable relative to the latching disc. A disadvantage of the known lighting device is that the locking disk 12 and the end cap must be surrounded by a common housing, wherein the housing is connected via fastening means fixed to the locking disk. The housing also has an end flange on which the end cap is held under tension by a spring.

Aufgabe der vorliegenden Erfindung ist es daher, eine Beleuchtungsvorrichtung mit einem eine Mehrzahl von LED-Lichtquellen enthaltenden Gehäuse derart weiterzubilden, dass zur Ausleuchtung eines Raumes auf einfache Weise ein abgestrahlter Lichtkegel quer zu einem Gehäuse der Beleuchtungsvorrichtung variierbar ist.Object of the present invention is therefore to develop a lighting device with a housing containing a plurality of LED light sources such that for illuminating a room in a simple manner, a radiated beam is transversely to a housing of the lighting device variable.

Zur Lösung der Aufgabe ist die Erfindung die Merkmale des Patentanspruches 1 auf.To achieve the object, the invention, the features of claim 1.

Der besondere Vorteil der Erfindung besteht darin, dass durch eine Verdrehbarkeit eines Basiskörpers und/oder einer Mehrzahl von LED-Lichtquellen relativ zu mit Kontaktierungen versehenen Endkappen ein von den LED-Lichtquellen abgestrahlter Lichtkegel einstell- und ausrichtbar zur Ausleuchtung eines vorgegebenen Raumes ist. Durch Einstellung eines wählbaren Verstelldrehwinkels kann der Lichtkegel relativ zu einer Aufnahme oder Fassung des Gehäuses verdreht positioniert werden, so dass unterschiedliche Raumbereiche ausleuchtbar sind.The particular advantage of the invention is that by rotatability of a base body and / or a plurality of LED light sources relative to endcaps provided with contacts a light cone emitted by the LED light sources can be adjusted and aligned to illuminate a predetermined space. By adjusting a selectable Verstelldrehwinkels the light cone can be positioned rotated relative to a receptacle or socket of the housing, so that different areas of space can be illuminated.

Nach der Erfindung ist eine Anzeigeeinheit vorgesehen, mittels derer der aktuell eingestellte Verstelldrehwinkel angezeigt wird. Auf diese Weise kann vor Montage des Gehäuses in die Aufnahme (Fassung) die gewünschte Verdrehung des Lichtkegels eingestellt werden.According to the invention, a display unit is provided, by means of which the currently set Verstelldrehwinkel is displayed. In this way, the desired rotation of the light cone can be adjusted before mounting the housing in the receptacle (version).

Nach der Erfindung ist die Endkappe um fest vorgegebene Verstelldrehwinkel zu dem Basiskörper und/oder den LED-Lichtquellen über eine Rasteinrichtung drehbar gelagert. Vorteilhaft kann hierdurch eine definierte relative Verdrehung zwischen der Endkappe und dem Basiskörper bzw. den LED-Lichtquellen herbeigeführt werden, wobei vorzugsweise die Verstelldrehwinkel gleich groß sind.According to the invention, the end cap is rotatably mounted by a predetermined setting angle of rotation to the base body and / or the LED light sources via a latching device. Advantageously, a defined relative rotation between the end cap and the base body or the LED light sources can thereby be brought about, wherein preferably the adjustment rotational angles are equal.

Nach der Erfindung umfasst die Rasteinrichtung zum einen eine Rastscheibe, die fest mit dem Basiskörper stirnseitig desselben verbunden ist. Diese Rastscheibe weist Rastaufnahmen auf, die mit fest mit der Endkappe verbundenen Rastelementen zusammenwirken. Die Rastaufnahmen der Rastscheibe sind vorzugsweise ringförmig in einem vorgegebenen Umfangsabstand zueinander angeordnet, so dass auf einfache Weise eine Mehrzahl von unterschiedlichen Verstellwinkeln einstellbar ist.According to the invention, the latching device comprises on the one hand a latching disc, which is connected to the base body of the same end face. This locking disc has locking receptacles, which cooperate with firmly connected to the end cap locking elements. The latching receptacles of the latching disc are preferably arranged in a ring shape at a predetermined circumferential distance from one another, so that a plurality of different adjustment angles can be set in a simple manner.

Nach der Erfindung ist die Endkappe in Axi'alrichtung federnd zu der Rastscheibe angeordnet. Vorteilhaft kann hierdurch eine rastende Verstellung durch Bewegungskombination eines axialen Herausziehens der Endkappe von dem Gehäuse und anschließender relativer Verdrehung desselben um die Längsachse des Gehäuses erfolgen.According to the invention, the end cap is arranged in the Axi'alrichtung resiliently to the locking disc. Advantageously, this can be done by latching adjustment by movement combination of an axial extraction of the end cap of the housing and subsequent relative rotation thereof about the longitudinal axis of the housing.

Weitere Vorteile der Erfindung ergeben sich aus den weiteren Unteransprüchen.Further advantages of the invention will become apparent from the further subclaims.

Innerhalb des Basiskörpers 2 ist eine Mehrzahl von nicht dargestellten LED-Lichtquellen angeordnet, die auf einer gemeinsamen Leiterplatte positioniert sind. Die Leiterplatte ist fest mit einer Rückseite 4 des Basiskörpers 2 verbunden. Die Rückseite 4 bildet einen nicht lichtdurchlässigen Umfangsabschnitt des Basiskörpers 2, der auf einer der LED-Lichtquellen abgewandten Seite der Leiterplatte angeordnet ist. Eine Vorderseite 5 des Basiskörpers 2 wird durch einen lichtdurchlässigen Umfangsabschnitt desselben gebildet, der auf einer den LED-Lichtquellen zugewandten Seite der Leiterplatte angeordnet ist. Die Vorderseite 5 und die Rückseite 4 des Basiskörpers können jeweils in Querschnitt halbkreisförmig ausgebildet sein, wobei sie sich jeweils über einen Umfangswinkel von 180° erstrecken. Die Rückseite 4 kann eine Rinne aus Aluminiummaterial; die Vorderseite 5 kann eine glasklare oder opake Rinne aus Kunststoff- oder Glasmaterial sein.A lighting device for illuminating private or public spaces, such as underground garages or the like, has a housing 1 which has an elongated base body 2 and two end caps 3 terminating the base body 2 at the end. Within the base body 2, a plurality of LED light sources, not shown, are arranged, which are positioned on a common printed circuit board. The printed circuit board is firmly connected to a rear side 4 of the base body 2. The back 4 forms a non-translucent peripheral portion of the base body 2, which is arranged on one side of the printed circuit board facing away from the LED light sources.
