Definitions
- the invention relates to a luminaire according to the preamble of claim 1 and a luminaire arrangement according to the preamble of claim 8.
- a luminaire which comprises a series of light-emitting diodes, which are attached to a common, designed as a board carrier.
- the LEDs are each provided with lenses to achieve a good radiation characteristics.
- two lenses are combined on a lens carrier, which is connected by means of locking elements with the carrier.
- both the production of these lenses, as well as the assembly is associated with considerable effort and costs.
- the object of the invention is to provide a cost-effective and easy to manufacture luminaire with light emitting diodes, which allows a simple influence on the radiation pattern, especially vertical surfaces should be illuminated evenly.
- the luminaire according to the invention is characterized in that a first of the two reflector regions has on one side of the support at least two mutually inclined planar surfaces.
- This structure of the first reflector region allows optimum influenceability of the emission characteristic of the luminaire for illuminating vertical walls or shelves and at the same time a simple and cost-effective production by bending or bending.
- the asymmetric light steering is achieved by an asymmetrical structure of the two opposing reflector areas with respect to the C90 plane running in the longitudinal direction of the luminaire.
- the first reflector region may also have more than two planar and mutually inclined surfaces.
- a second reflector region is formed on the other side of the carrier as a flat surface. This allows a sufficient deflection of the light radiation and at the same time a very simple production of this second reflector region.
- the angle between the first reflector region and the support may be between 90 ° and 150 °, preferably 110 °, and / or between the second reflector region and the support between 90 ° and 160 °, preferably 120 °.
- the angle between the two mutually inclined surfaces of the first reflector region may be between 1 ° and 60 °, preferably 15 °.
- the reflector and the carrier are integrally formed. This can be achieved, for example, by forming the reflector and the support from a planar workpiece, such as a metal or plastic sheet, by bending or bending. The manufacturing cost of such a construction is extremely low, resulting in low production costs.
- the carrier is integrated with the LEDs and the reflector in a housing, on which at two opposite ends a hinge for rotatable mounting with two suspensions is arranged.
- a luminaire arrangement according to the invention with at least two of the aforementioned lamps is claimed. This is characterized by the fact that the lights between two suspensions are arranged pivotably about a longitudinal axis.
- the lights can be mounted the other way around in the suspensions, so that both a symmetrical in cross-section, as well as a parallel orientation of the lights is possible.
- the luminaire arrangement can be used, for example, by a luminaire arranged in the middle of a corridor on the one hand for the uniform illumination of opposite vertical surfaces or shelves.
- one of the two lights can be mounted the other way round, so that both lights have a rectified radiation to increase the brightness of the illuminated area.
- the suspensions are designed as holding plates, which are connected by a substantially U-shaped longitudinal profile.
- the U-shaped longitudinal profile provides high rigidity and allows the easy placement of equipment such as the power supply for the LEDs.
- the suspensions may preferably have hinges for rotatable mounting of the lights. This makes it possible to freely rotate the lights relative to the suspensions to achieve the desired orientation of the lights.
- At least one connecting element for the displaceable fastening of the luminous arrangement in a rail can be arranged on the longitudinal profile.
- a lamp 1 is shown in cross-section, which consists of a series of light-emitting diodes 2 which are fixed to a common carrier 3.
- the course of the row of LEDs 2 is perpendicular to the image plane in this representation.
- a reflector 4 with two opposite reflector regions 5 and 6 is arranged on the support 3.

- a second reflector region 6 on the other side of the carrier 3 is formed as a flat surface.
- the reflector areas 5 and 6 are mirrored on the light emitting diodes 2 facing side or have a high reflectivity, so that the light of the LEDs 2 can be deflected almost lossless.
- the beam path of the lamp 1 is designed so that the lamp 1 mounted on the ceiling allows a uniform and continuous illumination of substantially vertical walls or shelves.
- the reflector areas 5 and 6 have an asymmetrical structure.
- the first reflector leg 5 has an approximately centrally arranged bend 9 between the flat surfaces 7 and 8.
- the angle ⁇ of the bend 9 is preferably 15 °.
- the light beams of the light-emitting diodes 2, which are deflected downwards by the first reflector region 5, strike deeper regions of the wall or of the shelf, so that these regions of the object to be illuminated, which are further away from the light 1, are illuminated sufficiently.
- the second reflector region 6 is formed as a flat surface. This is because the light rays, which are directed downwards anyway, need only be deflected slightly to hit the bottom of the wall or shelf.
- the angle ⁇ between the first reflector region 5 and the carrier 3 is preferably 110 °. This angle is mainly determined by the vertical and horizontal distance of the lamp 1 from the uppermost part of the wall or shelf to be illuminated.
- the angle ⁇ between the second reflector region 6 and the carrier 3 is preferably 120 °. This angle depends on the vertical and horizontal spacing of the luminaire 1 from the lowermost part of the wall or shelf to be illuminated.
- the carrier 3 is integrally formed with the reflector legs 5 and 6 and formed by bending or bending a flat workpiece, such as a metal or plastic sheet. This allows for a very simple production and on the other hand a high adaptability of the lamp 1 to different lighting requirements by simply changing the bending or bending angle.
- the angle ⁇ is achieved that a part of the light rays, which were originally directed towards the upper, the lamp 1 nearer wall parts are deflected downward and thus the loss of light intensity due to the further distance and the larger area in the lower part of the area to be filled.
- the lamp 1 shown results in an unusually uniform illumination without steps, which is especially important in the illumination of larger areas such as images or goods on shelves of shops is essential.
- FIG. 2 a luminaire assembly 10 is shown in cross-section, which has two of the aforementioned lamps 1. These lights 1 are each in a housing 11 of an elongated and in cross-section U-shaped profile body, such as a U-profile made of aluminum or plastic used.
- the housings 11 are each rotatably mounted at their opposite ends with hinges 12 to suspensions 13.
- the suspensions 13 are formed as holding plates, which are connected by a substantially U-shaped longitudinal profile 14, within which the electronics for the lights 1 can be arranged.
- the hinges 12 make it possible to align the lights 1 with the light rays during assembly in a simple manner to the areas to be illuminated.
- the luminaire arrangement 10 is designed for the illumination of two walls or shelves, which are located at approximately the same distance laterally to the luminaire arrangement 10. In this case, each lamp 1 lit only a wall or a shelf.
- each of the luminaires 1 is as in the embodiment of FIG. 2 rotatably mounted about the pivot joints 12.
- a connecting element 15 is shown, which is connected to the U-shaped longitudinal profile 13.

Description
Die Erfindung betrifft eine Leuchte nach dem Oberbegriff des Anspruchs 1 und eine Leuchtenanordnung nach dem Oberbegriff des Anspruchs 8.The invention relates to a luminaire according to the preamble of
Aus der
Aus der
Aufgabe der Erfindung ist es, eine kostengünstig und einfach herstellbare Leuchte mit Leuchtdioden zu schaffen, die eine einfache Beeinflussung der Abstrahlcharakteristik ermöglicht, wobei speziell vertikale Flächen gleichmäßig ausgeleuchtet werden sollen.The object of the invention is to provide a cost-effective and easy to manufacture luminaire with light emitting diodes, which allows a simple influence on the radiation pattern, especially vertical surfaces should be illuminated evenly.
Diese Aufgabe wird durch eine Leuchte mit den Merkmalen des Anspruchs 1 und eine Leuchtenanordnung mit den Merkmalen des Anspruchs 8 gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen angegeben.This object is achieved by a luminaire having the features of
Die erfindungsgemäße Leuchte zeichnet sich dadurch aus, dass ein erster der beiden Reflektorbereiche auf der einen Seite des Trägers mindestens zwei zueinander geneigte ebene Flächen aufweist. Dieser Aufbau des ersten Reflektorbereichs ermöglicht eine optimale Beeinflussbarkeit der Abstrahlcharakteristik der Leuchte zur Ausleuchtung vertikaler Wände bzw. Regale und zugleich eine einfache und kostengünstige Herstellung durch Abkanten bzw. Krümmen. Die asymmetrische Lichtlenkung wird durch einen asymmetrischen Aufbau der zwei sich gegenüberliegenden Reflektorbereiche im Bezug auf die in Längsrichtung der Leuchte verlaufende C90-Ebene erreicht.The luminaire according to the invention is characterized in that a first of the two reflector regions has on one side of the support at least two mutually inclined planar surfaces. This structure of the first reflector region allows optimum influenceability of the emission characteristic of the luminaire for illuminating vertical walls or shelves and at the same time a simple and cost-effective production by bending or bending. The asymmetric light steering is achieved by an asymmetrical structure of the two opposing reflector areas with respect to the C90 plane running in the longitudinal direction of the luminaire.
Der erste Reflektorbereich kann jedoch auch mehr als zwei ebene und zueinander geneigte Flächen aufweisen. So ist es auch möglich, durch eine Vielzahl von Biegungen den ersten Reflektorbereich mit einer durchgehenden Krümmung zu versehen.However, the first reflector region may also have more than two planar and mutually inclined surfaces. Thus, it is also possible to provide the first reflector region with a continuous curvature through a plurality of bends.
In einer bevorzugten Ausführungsform ist ein zweiter Reflektorbereich auf der anderen Seite des Trägers als ebene Fläche ausgebildet. Dies ermöglicht eine ausreichende Umlenkung der Lichtstrahlung und zugleich eine sehr einfache Herstellung dieses zweiten Reflektorbereichs.In a preferred embodiment, a second reflector region is formed on the other side of the carrier as a flat surface. This allows a sufficient deflection of the light radiation and at the same time a very simple production of this second reflector region.
In einer zweckmäßigen Ausführungsform kann der Winkel zwischen dem ersten Reflektorbereich und dem Träger zwischen 90° und 150°, vorzugsweise 110°, und/oder zwischen dem zweiten Reflektorbereich und dem Träger zwischen 90° und 160°, vorzugsweise 120°, betragen. Der Winkel zwischen den zwei zueinander geneigten Flächen des ersten Reflektorbereichs kann zwischen 1° und 60°, vorzugsweise 15°, betragen. Diese Winkel ermöglichen für sich alleine oder auch in Kombination eine besonders gleichmäßige Ausleuchtung vertikaler Flächen wie Wänden und im Besonderen von Regalen. Zur Verringerung der Blendung in der C90-Ebene der Leuchte können optional Blendraster parallel zur C0-Ebene der Leuchte angebracht werden.In an expedient embodiment, the angle between the first reflector region and the support may be between 90 ° and 150 °, preferably 110 °, and / or between the second reflector region and the support between 90 ° and 160 °, preferably 120 °. The angle between the two mutually inclined surfaces of the first reflector region may be between 1 ° and 60 °, preferably 15 °. These angles, on their own or in combination, allow a particularly uniform illumination of vertical surfaces such as walls and in particular of shelves. In order to reduce the glare in the C90-level of the luminaire, it is possible to optionally install glare grids parallel to the C0-plane of the luminaire.
In einer weiteren vorteilhaften Ausführungsform sind der Reflektor und der Träger einstückig ausgebildet. Dies kann beispielsweise dadurch erreicht werden, dass der Reflektor und der Träger aus einem ebenen Werkstück, wie beispielsweise einem Metall- oder Kunststoffblech, durch abkanten bzw. biegen geformt werden. Der Fertigungsaufwand einer solchen Bauweise ist äußerst gering, was niedrige Herstellungskosten zur Folge hat.In a further advantageous embodiment, the reflector and the carrier are integrally formed. This can be achieved, for example, by forming the reflector and the support from a planar workpiece, such as a metal or plastic sheet, by bending or bending. The manufacturing cost of such a construction is extremely low, resulting in low production costs.
Es ist zudem in einer vorteilhaften Ausführungsform der Leuchte vorgesehen, dass der Träger mit den Leuchtdioden und dem Reflektor in einem Gehäuse integriert ist, an dem an zwei gegenüberliegenden Enden ein Drehgelenk zur drehbaren Befestigung mit zwei Aufhängungen angeordnet ist. Dies ermöglicht es, die Lampe je nach Bedarf zu drehen und so einen optimalen Anstrahlwinkel der Leuchte auf das zu beleuchtende Objekt einzustellen. Zudem wird auch eine erfindungsgemäße Leuchtenanordnung mit mindestens zwei der vorgenannten Leuchten beansprucht. Diese zeichnet sich dadurch aus, dass die Leuchten zwischen zwei Aufhängungen schwenkbar um eine Längsachse angeordnet sind. Zudem können die Leuchten auch anders herum in den Aufhängungen montiert werden, so dass sowohl eine im Querschnitt symmetrische, wie auch eine parallele Ausrichtung der Leuchten möglich ist. Hierdurch kann die Leuchtenanordnung z.B. durch eine in der Mitte eines Gangs angeordnete Leuchte einerseits zur gleichmäßigen Ausleuchtung gegenüberliegender vertikaler Flächen bzw. Regale verwendet werden. Andererseits kann auch eine der beiden Leuchten anders herum montiert werden, so dass beide Leuchten eine gleichgerichtete Ausstrahlung aufweisen, um die Helligkeit der beleuchteten Fläche zu erhöhen.It is also provided in an advantageous embodiment of the lamp, that the carrier is integrated with the LEDs and the reflector in a housing, on which at two opposite ends a hinge for rotatable mounting with two suspensions is arranged. This makes it possible to turn the lamp as needed, and so set an optimal angle of the light on the object to be illuminated. In addition, a luminaire arrangement according to the invention with at least two of the aforementioned lamps is claimed. This is characterized by the fact that the lights between two suspensions are arranged pivotably about a longitudinal axis. In addition, the lights can be mounted the other way around in the suspensions, so that both a symmetrical in cross-section, as well as a parallel orientation of the lights is possible. As a result, the luminaire arrangement can be used, for example, by a luminaire arranged in the middle of a corridor on the one hand for the uniform illumination of opposite vertical surfaces or shelves. On the other hand, one of the two lights can be mounted the other way round, so that both lights have a rectified radiation to increase the brightness of the illuminated area.
In einer bevorzugten Ausführungsform der Leuchtenanordnung sind die Aufhängungen als Halteplatten ausgebildet, die durch ein im Wesentlichen U-förmiges Längsprofil verbunden sind. Das U-förmige Längsprofil bietet eine hohe Steifigkeit und ermöglicht die problemlose Unterbringung von Betriebsmitteln wie der Spannungsversorgung für die Leuchtdioden.In a preferred embodiment of the luminaire arrangement, the suspensions are designed as holding plates, which are connected by a substantially U-shaped longitudinal profile. The U-shaped longitudinal profile provides high rigidity and allows the easy placement of equipment such as the power supply for the LEDs.
Die Aufhängungen können bevorzugt Drehgelenke zur drehbaren Befestigung der Leuchten aufweisen. Hierdurch wird es möglich, die Leuchten relativ zu den Aufhängungen frei zu drehen, um die gewünschte Ausrichtung der Leuchten zu erreichen.The suspensions may preferably have hinges for rotatable mounting of the lights. This makes it possible to freely rotate the lights relative to the suspensions to achieve the desired orientation of the lights.
An dem Längsprofil kann zudem vorteilhafterweise mindestens ein Verbindungselement zum verschiebbaren Befestigen der Leuchtenanordnung in einer Schiene angeordnet sein. Hierdurch wird eine rasche Verstellbarkeit der Position der Leuchtenanordnung in Richtung der Schiene ermöglicht.In addition, advantageously at least one connecting element for the displaceable fastening of the luminous arrangement in a rail can be arranged on the longitudinal profile. As a result, a rapid adjustability of the position of the lamp assembly is made possible in the direction of the rail.

In
Der Strahlengang der Leuchte 1 ist so ausgelegt, dass die Leuchte 1 an der Decke montiert eine gleichmäßige und stufenlose Ausleuchtung von im Wesentlichen vertikalen Wänden oder Regalen ermöglicht. Dazu weisen die Reflektorbereiche 5 und 6 einen asymmetrischen Aufbau auf. Der erste Reflektorschenkel 5 hat einen in etwa mittig angeordneten Knick 9 zwischen den ebenen Flächen 7 und 8. Der Winkel α des Knicks 9 liegt vorzugsweise bei 15°. Die durch den ersten Reflektorbereich 5 nach unten abgelenkten Lichtstrahlen der Leuchtdioden 2 treffen auf tiefere Bereiche der Wand bzw. des Regals, so dass auch diese von der Leuchte 1 weiter entfernten Bereiche des zu beleuchtenden Objekts ausreichend angeleuchtet werden.The beam path of the
Im Gegensatz dazu ist der zweite Reflektorbereich 6 als ebene Fläche ausgebildet. Dies hat den Grund, dass die ohnehin nach unten gerichteten Lichtstrahlen nur wenig umgelenkt werden müssen, um auf die unteren Bereiche der Wand bzw. des Regals zu treffen.In contrast, the
Der Winkel β zwischen dem ersten Reflektorbereich 5 und dem Träger 3 beträgt vorzugsweise 110°. Dieser Winkel bestimmt sich hauptsächlich aus dem vertikalen und horizontalen Abstand der Leuchte 1 von dem obersten zu beleuchtenden Teil der Wand bzw. des Regals. Der Winkel γ zwischen dem zweiten Reflektorbereich 6 und dem Träger 3 beträgt bevorzugt 120°. Dieser Winkel hängt von dem vertikalen und horizontalen Abstand der Leuchte 1 von dem untersten zu beleuchtenden Teil der Wand bzw. des Regals ab.The angle β between the
In dem gezeigten Ausführungsbeispiel ist der Träger 3 mit den Reflektorschenkeln 5 und 6 einstückig ausgeführt und durch abkanten bzw. biegen eines ebenen Werkstücks, wie beispielsweise einem Metall- oder Kunststoffblech, geformt. Dies ermöglicht zum einen eine sehr einfache Fertigung und zum anderen eine hohe Anpassbarkeit der Leuchte 1 an verschiedene Beleuchtungsanforderungen durch einfache Änderung der Abkant- bzw. Biegewinkel.In the illustrated embodiment, the
Speziell durch den Winkel α wird erreicht, dass ein Teil der Lichtstrahlen, die ursprünglich in Richtung der oberen, der Leuchte 1 näheren Wandteile gerichtet waren, nach unten abgelenkt werden und somit der Verlust an Lichtintensität aufgrund der weiteren Entfernung und der größeren Fläche im unteren Teil des anzuleuchtenden Bereichs ausgeglichen werden kann. Als Resultat ergibt sich durch die dargestellte Leuchte 1 eine ungewöhnlich gleichmäßige Ausleuchtung ohne Stufen, was vor allem bei der Beleuchtung von größeren Flächen wie Bildern oder auch von Waren in Regalen von Geschäften von wesentlicher Bedeutung ist.Specifically, by the angle α is achieved that a part of the light rays, which were originally directed towards the upper, the
