Definitions
- the present invention relates to a luminaire according to the preamble of claim 1, which is designed to emit light in such a way that the so-called light distribution curve has two wings inclined relative to the vertical or longitudinal median plane of the luminaire, via which the light is primarily emitted.
- the invention relates to a luminaire, which is used for example in shops or shops and is intended to illuminate shelves.
- a typical application of generic lights are, for example, supermarkets, where the products or goods are arranged in longer, mutually parallel rows of shelves.
- luminaires are usually used, which are arranged centrally above between two adjacent rows of shelves, for example on the ceiling of the room or also suspended therefrom and are designed such that they obliquely downward their light in two directions facing away from each other, So in each case in the direction of the obliquely located below rows of shelves.
- the total resulting light emission characteristic of the lamp corresponds to a so-called Batwing distribution, which is characterized by two with respect to the vertical obliquely aligned wing-like maxima in the light distribution curve.
- the light of the lamp is therefore not primarily down vertically but instead each slightly laterally down in two opposite directions.
- a disadvantage of these known solutions is that an adaptation of the light distribution curve to actual conditions on site usually is difficult. Whether the light emitted by the light actually illuminates the shelves below obliquely depends in particular on how well the light distribution curve is suitable for the arrangement of the lamp with respect to the rows of shelves. That is, the Lichtabstrahl characterizing should on the one hand be adapted to the distance between the rows of shelves and on the other hand, the distance between light and rows of shelves. Since in the case of lenses, a change in the light emission characteristic is usually difficult to achieve, this means that the light for the specific application must always be positioned at a suitable height with respect to the rows of shelves, which may be feasible only with great effort.
- EP 2 650 595 A1 describes a lamp with a lamp housing for wall and / or ceiling mounting, a linear lamp having a plurality of LEDs, a holding device for fixing the respective lamp to the lamp housing, which is arranged between the two longitudinal ends of the respective lamp, and a power electronics for power supply Lamp which is arranged on or in the luminaire housing outside of the respective lamp and which is electrically connected to the housing-side primary electrical connections, via which the lamp is electrically connected to a power grid.
- a generic light is from the EP1273849A2 known.
- the present invention has for its object to provide a luminaire of the type described above, in which the Lichtabstrahl characterizing can be adjusted or modified in a relatively simple manner.
- the luminaire has two illumination units, which are arranged side by side with respect to a longitudinal center plane of the luminaire and are designed such that they effect a light output facing away from one another in a plane perpendicular to the longitudinal axis of the luminaire.
- Each lighting unit is therefore responsible for the delivery of a light cone of the total desired Batwing distribution, which is discharged laterally down, for example, on a row of shelves.
- the invention provides that both illumination units are adjustable about a respective pivot axis extending parallel to the longitudinal axis of the lamp.
- a luminaire with two lighting units wherein the lighting units are arranged side by side with respect to a longitudinal axis of the lamp and are formed such that they effect a mutually remote light output in a plane perpendicular to the longitudinal axis of the lamp and according to the invention the two lighting units to a respective axis of rotation extending parallel to the longitudinal axis are adjustable.
- Each lighting unit has in this case lighting means and an associated reflector, wherein the arrangement of the lighting means and the design of the reflector is such that substantially only reflected by the reflector light beams can leave the light.
- the reflector is used in this case as a so-called back reflector, whereby the possibilities to influence the light output can be improved. Another advantage of this type of light output is that the possibility of glare control is optimized.
- the lamps of the luminaire according to the invention are LEDs which are arranged on one or more circuit boards. Again, for reasons of glare, the boards are arranged so that they are inclined in each possible position of the lighting unit. This prevents a direct view of the LEDs even when viewed from below.
- the orientation of the respective maximum of the Batwing light distribution curve can be adjusted.
- it is possible to make an individual adjustment for both maxima of the light distribution curve that is to say so
- the possibility of adjusting the lighting units is limited to an angular range of about 10 °.
- each lighting unit is associated with an individual heat sink, which is then pivoted together with the lighting unit and in particular is thermally coupled to the LEDs.
- a particularly efficient heat coupling can be achieved in that the LED boards or a support element for the LED boards is designed angled and perpendicular to the support surface for the LEDs aligned leg of the support member or the board in a running in the longitudinal direction of the heat sink recess intervenes. That is, the heat sink also serves to hold the LEDs and heat dissipation is optimized.
- the reflector of a lighting unit is preferably executed at least partially curved in a plane perpendicular to the longitudinal axis of the lamp in order to achieve the desired light distribution.
- a broad distribution of light is desired, so that here the reflector is designed unchanged, at least over a certain longitudinal section.
- the reflector then preferably has inclined surface sections at its end regions.
- the lighting units are preferably arranged inside half of a housing whose end faces can be made approximately X-shaped. As a result, the lamp has a particularly appealing and interesting appearance, in spite of which optimal light emission properties are present.
- the luminaire according to the invention serves primarily to be arranged, for example, in shops or shops above shelves and to illuminate the shelves which are located obliquely below the luminaire.
- the lamp could also be used for other purposes, for example, to illuminate the side walls of an elongated passage or the like.
- the luminaire 100 is in this case designed to be relatively compact, but extends in spite of all along an in FIG. 1 shown longitudinal axis I.
- end walls 115 are arranged, which - in particular the representations of Figures 1 and 2 can be removed - have approximately an X-shape. This gives the lamp a special characteristic appearance, which is also emphasized by the manner described below in more detail of the light output.
- the luminaire 100 will be arranged centrally above two rows of shelves extending parallel to one another and will then illuminate these two rows of shelves. That is, as in FIG. 2 indicated with the help of the lamp 100, a light output can be achieved, which in particular by two laterally obliquely downwardly directed radiation maxima A and B (see FIG. 2 ). This corresponds to a so-called batwing light distribution curve, in which therefore the light is not emitted primarily vertically downwards but instead in two beams facing away from each other laterally downwards.
- the lamp 100 is equipped with special lighting units, which will be described in more detail below.
- illumination units which are generally provided with the reference numeral 10, are particularly clearly recognizable in the sectional representation according to FIG. 3 , It is initially apparent that both illumination units 10 are arranged side by side back to back with respect to the longitudinal axis I of the lamp 100 and the longitudinal center plane and are designed such that they each generate one of the downwardly laterally directed radiation beams A and B. Both lighting units 10 are made identical, whereby the structure of the lamp 100 is simplified as a whole.
- each of the lighting units 10 As a lighting means for each of the lighting units 10 while LEDs 15 are used, which are each arranged on one or more boards 16.
- the light emitted by the LEDs 15 light is not emitted directly in the desired direction, but initially primarily emitted in an opposite direction, ie to the longitudinal center plane of the lamp 100 out. Only after the light beams have been reflected by a rear reflector 20, they can leave the lighting unit 10 and the lamp housing 110, wherein - as in FIG. 3 can be seen - the arrangement of the LED boards 16 and the design of the rear reflectors 20 is such that the light output is primarily obliquely down.
- each lighting unit 10 is a heat sink 25, with the help of which the heat generated by the LEDs 15 during operation of the lamp 100 heat to be dissipated.
- a heat sink 25 For this purpose, an efficient thermal coupling between LED board 16 and heat sink 25 is advantageous, which according to a particularly preferred embodiment as in the enlarged view of FIG. 6 is realized shown.
- the LED board 16 is arranged on an angled support member 17, which has a first web 17 1 , on which the circuit board 16 rests.
- an approximately perpendicular to the first web 17 1 aligned second web 17 2 is provided which is inserted into a running in the longitudinal direction of the heat sink 25 recess 26 and optionally fixed there.
- the heat sink 25 itself is formed in a known manner with a plurality of longitudinally extending cooling fins 27, so that the largest possible contact surface with the environment is achieved to deliver the heat to the environment.
- Other possibilities for coupling between LED board 16 and heat sink 25 would be conceivable.
- Each lighting unit 10 thus consists primarily of the LED lamps 15 and the LED board 16, the rear reflector 20 and the associated heat sink 25. According to the invention, it is now provided that the lighting units 10 are adjustably arranged within the housing 110 of the lamp 100 , As here in FIG. 3 can be seen, there is a suspension of the lighting units 10 such that in each case a parallel to the longitudinal axis of the lamp I extending pivot axis II is formed, by which the respective lighting unit 10 can be pivoted.
- a specific light distribution curve for the illumination unit 10 is achieved, which has a single, obliquely downward maximum, this means that by pivoting the entire lighting unit 10, the orientation of the maximum of the light output of the lamp can be changed.
- the light output of a single illumination unit 10 is thus characterized-in the section perpendicular to the longitudinal axis I of the light-by a single beam whose orientation can be changed by pivoting the illumination unit 10 as a whole.
- the orientation and shape of the beam emitted laterally downwards is achieved by the curvature of the reflector 20 and the orientation of the LEDs 15. It is provided in particular that the LED boards 16 are not completely vertical, but instead slightly inclined aligned, such that the lower edge of the sinker is closer to the longitudinal center plane of the lamp 100 than the corresponding upper edge, regardless of the degree of pivoting of the associated Lighting unit 10.
- the illumination unit 10 has an outside of the LED board 16 extending, extending over approximately half the height side wall 11, which on its underside an inwardly directed, angled Web 12 has.
- This lower end region of the side wall 11 defines, together with the reflector 20, a light exit opening, via which the light output of the illumination unit 10 takes place.
- the reflectors 20 are intended to generate a relatively narrow beam in a plane perpendicular to the longitudinal axis I, which, as mentioned, is achieved by the arrangement of the LEDs 15 and the curvature of the reflector 20.
- the widest possible light distribution should be present in order to ensure that despite the relatively short length of the lamp 100, a larger portion underneath lying shelves can be illuminated.
- the reflector 20 is designed unchanged or translation-invariant with respect to its reflection surface 21 in a central region in the longitudinal direction. At its two end portions, however, it has inclined surface portions 22, in particular in the Figures 2 . 4 and 5 are recognizable.
- This particular embodiment of the reflectors 20 also leads to a view of the lamp 100 from below, as in FIG. 5 is shown, again gives a special appearance.
- these reflection surfaces lead to a bright luminous, approximately X-shaped area. This can be assisted, for example, by forming the further components of the housing 110 from a dark or black material compared to the reflectors 20.
- the luminaire according to the invention has an extremely interesting appearance, also with regard to the area over which the light is emitted.
- the luminaire fulfills all the requirements for a luminaire for illuminating, for example, rows of shelves in shops with regard to its light-emitting properties, wherein, moreover, it is also possible to adapt the light distribution, as a result of which the fields of use or use can be significantly improved.

Description
Die vorliegende Erfindung betrifft eine Leuchte gemäß dem Oberbegriff des Anspruchs 1, welche dazu ausgebildet ist, Licht derart abzugeben, dass die sog. Lichtverteilungskurve zwei gegenüber der Vertikalen bzw. Längsmittelebene der Leuchte geneigte Flügel aufweist, über die primär das Licht abgegeben wird. Insbesondere betrifft die Erfindung eine Leuchte, welche beispielsweise in Geschäften oder Shops zum Einsatz kommt und dazu vorgesehen ist, Regale zu beleuchten.The present invention relates to a luminaire according to the preamble of claim 1, which is designed to emit light in such a way that the so-called light distribution curve has two wings inclined relative to the vertical or longitudinal median plane of the luminaire, via which the light is primarily emitted. In particular, the invention relates to a luminaire, which is used for example in shops or shops and is intended to illuminate shelves.
Ein typisches Einsatzgebiet gattungsgemäßer Leuchten sind beispielsweise Supermärkte, bei denen die Produkte oder Waren in längeren, parallel zueinander verlaufenden Regalreihen angeordnet sind. Um die Regale auszuleuchten, kommen in der Regel Leuchten zum Einsatz, welche mittig oberhalb zwischen zwei benachbarten Regalreihen, beispielsweise an der Decke des Raums oder auch abgehängt davon angeordnet und derart ausgeführt sind, dass sie ihr Licht schräg nach unten in zwei voneinander abgewandte Richtungen, also jeweils in Richtung der schräg darunter befindlichen Regalreihen abgeben. Die sich hierbei insgesamt ergebende Lichtabstrahlcharakteristik der Leuchte entspricht dabei einer so genannten Batwing-Verteilung, welche sich durch zwei gegenüber der Vertikalen schräg ausgerichtete flügelartige Maxima in der Lichtverteilungskurve auszeichnet. Das Licht der Leuchte wird also nicht primär senkrecht nach unten sondern stattdessen jeweils leicht seitlich nach unten in zwei entgegengesetzte Richtungen abgegeben.A typical application of generic lights are, for example, supermarkets, where the products or goods are arranged in longer, mutually parallel rows of shelves. In order to illuminate the shelves, luminaires are usually used, which are arranged centrally above between two adjacent rows of shelves, for example on the ceiling of the room or also suspended therefrom and are designed such that they obliquely downward their light in two directions facing away from each other, So in each case in the direction of the obliquely located below rows of shelves. The total resulting light emission characteristic of the lamp corresponds to a so-called Batwing distribution, which is characterized by two with respect to the vertical obliquely aligned wing-like maxima in the light distribution curve. The light of the lamp is therefore not primarily down vertically but instead each slightly laterally down in two opposite directions.
Zum Erzielen einer derartigen Lichtabstrahlcharakteristik sind aus dem Stand der Technik verschiedene Lösungen bekannt. Beispielsweise wurden lichtbrechende Optiken in Form von Linsen oder dergleichen entwickelt, welche das von der bzw. den Lichtquellen abgegebene Licht in Art eines Strahlteilers in zwei Bündel aufteilen, welche dann jeweils seitlich nach unten hin abgegeben werden. Auch andere optische Systeme sind bekannt, welche das Licht der Leuchtmittel in der oben beschriebenen Weise entsprechend beeinflussen, wobei auch bekannt ist, für jedes Strahlenbündel eigene Leuchtmittel zu verwenden.To achieve such a Lichtabstrahlcharakteristik different solutions are known from the prior art. For example, refractive optics in the form of lenses or the like have been developed, which divide the light emitted by the light source or sources in the manner of a beam splitter into two bundles, which are then discharged laterally downwards. Other optical systems are known which influence the light of the lighting means in the manner described above accordingly, wherein it is also known to use for each beam own bulbs.
Ein Nachteil dieser bekannten Lösungen besteht allerdings darin, dass ein Anpassen der Lichtverteilungskurve an tatsächliche Gegebenheiten vor Ort in der Regel nur schwer möglich ist. Ob das von der Leuchte abgegebene Licht die schräg unterhalb befindlichen Regale tatsächlich effizient ausleuchtet hängt dabei insbesondere davon ab, wie gut die Lichtverteilungskurve für die Anordnung der Leuchte bezüglich der Regalreihen geeignet ist. Das heißt, die Lichtabstrahlcharakteristik sollte einerseits an den Abstand zwischen den Regalreihen sowie andererseits den Abstand zwischen Leuchte und Regalreihen angepasst sein. Da im Falle von Linsen eine Veränderung der Lichtabstrahlcharakteristik in der Regel nur schwer realisierbar ist, bedeutet dies, dass die Leuchte für den speziellen Anwendungsfall immer in geeigneter Höhe bezüglich der Regalreihen positioniert werden muss, was ggf. nur mit einem hohen Aufwand realisierbar ist.
Es wäre also eine gewisse Flexibilität bei der Einstellung der Lichtverteilungskurve einer derartigen Leuchte wünschenswert, da dann größere Freiheiten hinsichtlich der Anordnung der Leuchten bestehen würden. Das heißt, diese könnten nunmehr im Wesentlichen unabhängig vom Abstand der Regalreihen zueinander flexibel in einer gewünschten Höhe bezüglich der zu beleuchtenden Regale positioniert werden, da dann lediglich die Lichtverteilungskurve in geeigneter Weise angepasst werden muss.
Darüber hinaus kann auch durchaus der Fall auftreten, dass zu bestimmten Zeitpunkten bestimmte Bereiche eines Regals zur Hervorhebung bestimmter Produkte gezielt bzw. heller beleuchtet werden sollen. Beispielsweise könnte also gewünscht sein, das Maximum der Helligkeit auf das obere Drittel des Regals zu konzentrieren, da hier Produkte in besonders intensiver Weise hervorgehoben werden sollen. Auch dies ist nur dann möglich, wenn eine Anpassung der Lichtabstrahlcharakteristik der Leuchte verhältnismäßig einfach durch den Endverbraucher vorgenommen werden kann. Der
So it would be desirable a degree of flexibility in adjusting the light distribution curve of such a luminaire, since then greater freedom would exist in terms of the arrangement of the lights. That is, these could now be positioned substantially independent of the distance of the rows of shelves to each other flexibly at a desired height with respect to the shelves to be illuminated, since then only the light distribution curve must be adjusted in a suitable manner.
In addition, it may well be the case that at certain times certain areas of a shelf for highlighting certain products should be targeted or brighter illuminated. For example, it might thus be desirable to concentrate the maximum of the brightness on the upper third of the shelf, since products should be highlighted in a particularly intensive manner here. Again, this is only possible if an adjustment of the light emission characteristic of the lamp can be made relatively easy by the end user. Of the
Die Aufgabe wird durch eine Leuchte, welche die Merkmale des Anspruchs 1 aufweist, gelöst. Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der abhängigen Ansprüche.The object is achieved by a luminaire having the features of claim 1. Advantageous developments of the invention are the subject of dependent claims.
Gemäß der vorliegenden Erfindung ist vorgesehen, dass die Leuchte zwei Beleuchtungseinheiten aufweist, welche bezüglich einer Längsmittelebene der Leuchte nebeneinander angeordnet und derart ausgebildet sind, dass sie in einer Ebene senkrecht zur Längsachse der Leuchte eine voneinander abgewandte Lichtabgabe bewirken. Jede Beleuchtungseinheit ist also für die Abgabe eines Lichtkegels der insgesamt angestrebten Batwing-Verteilung verantwortlich, der seitlich nach unten beispielsweise auf eine Regalreihe abgegeben wird. Dabei ist erfindungsgemäß vorgesehen, dass beide Beleuchtungseinheiten um eine jeweils parallel zur Längsachse der Leuchte verlaufende Schwenkachse verstellbar sind.According to the present invention, it is provided that the luminaire has two illumination units, which are arranged side by side with respect to a longitudinal center plane of the luminaire and are designed such that they effect a light output facing away from one another in a plane perpendicular to the longitudinal axis of the luminaire. Each lighting unit is therefore responsible for the delivery of a light cone of the total desired Batwing distribution, which is discharged laterally down, for example, on a row of shelves. In this case, the invention provides that both illumination units are adjustable about a respective pivot axis extending parallel to the longitudinal axis of the lamp.
Gemäß der vorliegenden Erfindung wird also eine Leuchte mit zwei Beleuchtungseinheiten vorgeschlagen, wobei die Beleuchtungseinheiten bezüglich einer Längsachse der Leuchte nebeneinander angeordnet und derart ausgebildet sind, dass sie in einer Ebene senkrecht zur Längsachse der Leuchte eine voneinander abgewandte Lichtabgabe bewirken und wobei erfindungsgemäß die beiden Beleuchtungseinheiten um eine jeweils parallel zur Längsachse verlaufende Schwenkachse verstellbar sind.According to the present invention, therefore, a luminaire with two lighting units is proposed, wherein the lighting units are arranged side by side with respect to a longitudinal axis of the lamp and are formed such that they effect a mutually remote light output in a plane perpendicular to the longitudinal axis of the lamp and according to the invention the two lighting units to a respective axis of rotation extending parallel to the longitudinal axis are adjustable.
Jede Beleuchtungseinheit weist dabei Leuchtmittel sowie einen zugehörigen Reflektor auf, wobei die Anordnung der Leuchtmittel und die Gestaltung des Reflektors derart ist, dass im Wesentlichen lediglich von dem Reflektor reflektierte Lichtstrahlen die Leuchte verlassen können. Der Reflektor dient in diesem Fall also als so genannter Rückreflektor, wodurch die Möglichkeiten, Einfluss auf die Lichtabgabe nehmen zu können, verbessert werden. Ein weiterer Vorteil dieser Art der Lichtabgabe besteht auch darin, dass die Möglichkeit zur Entblendung der Leuchte optimiert wird.Each lighting unit has in this case lighting means and an associated reflector, wherein the arrangement of the lighting means and the design of the reflector is such that substantially only reflected by the reflector light beams can leave the light. The reflector is used in this case as a so-called back reflector, whereby the possibilities to influence the light output can be improved. Another advantage of this type of light output is that the possibility of glare control is optimized.
Bei den Leuchtmitteln der erfindungsgemäßen Leuchte handelt es sich um LEDs, welche auf einer oder mehreren Platinen angeordnet sind. Wiederum aus Gründen der Entblendung sind die Platinen derart angeordnet, dass sie in jeder möglichen Stellung der Beleuchtungseinheit geneigt ausgerichtet sind. Hierdurch wird verhindert, dass auch bei Ansicht von unten ein unmittelbarer Blick auf die LEDs vorliegt.The lamps of the luminaire according to the invention are LEDs which are arranged on one or more circuit boards. Again, for reasons of glare, the boards are arranged so that they are inclined in each possible position of the lighting unit. This prevents a direct view of the LEDs even when viewed from below.
Durch die Möglichkeit, die Beleuchtungseinheiten zumindest in einem bestimmten Winkelbereich zu verstellen, kann also die Ausrichtung des jeweiligen Maximums der Batwing-Lichtverteilungskurve eingestellt werden. Dabei besteht insbesondere bei der erfindungsgemäßen Lösung die Möglichkeit, für beide Maxima der Lichtverteilungskurve eine individuelle Einstellung vorzunehmen, sodass also hinsichtlich der Anpassung der Lichtabstrahleigenschaften der Leuchte eine besonders hohe Flexibilität vorliegt. Damit kann nicht nur die Lichtabgabe optimiert an eine bestimmte Positionierung der Leuchte im Hinblick auf zu beleuchtende Regalreihen angepasst werden, sondern es besteht auch die Möglichkeit, gegebenenfalls gezielt bestimmte Höhenbereiche eines seitlich unterhalb der Leuchte befindlichen Regals auszuleuchten. Vorzugsweise ist hierbei die Möglichkeit der Verstellung der Beleuchtungseinheiten auf einen Winkelbereich von etwa 10° beschränkt.By the possibility of adjusting the lighting units at least in a certain angular range, so the orientation of the respective maximum of the Batwing light distribution curve can be adjusted. In this case, in particular in the case of the solution according to the invention, it is possible to make an individual adjustment for both maxima of the light distribution curve, that is to say so There is a particularly high level of flexibility with regard to the adaptation of the light-emitting properties of the luminaire. Thus, not only the light output can be optimized adapted to a specific positioning of the lamp with respect to rows of shelves to be illuminated, but it is also possible, if appropriate, specifically illuminate certain height ranges of a laterally located below the lamp shelf. Preferably, the possibility of adjusting the lighting units is limited to an angular range of about 10 °.
Ferner kann vorgesehen sein, dass jeder Beleuchtungseinheit ein individueller Kühlkörper zugeordnet ist, der dann gemeinsam mit der Beleuchtungseinheit verschwenkt und insbesondere mit den LEDs thermisch gekoppelt ist. Eine besonders effiziente Wärmekopplung kann dabei dadurch erzielt werden, dass die LED-Platinen oder ein Trägerelement für die LED-Platinen abgewinkelt ausgeführt ist und ein senkrecht zur Auflagefläche für die LEDs ausgerichteter Schenkel des Trägerelements bzw. der Platine in eine in Längsrichtung des Kühlkörpers verlaufende Ausnehmung eingreift. Das heißt, der Kühlkörper dient gleichzeitig auch der Halterung der LEDs und die Wärmeableitung wird optimiert.Furthermore, it can be provided that each lighting unit is associated with an individual heat sink, which is then pivoted together with the lighting unit and in particular is thermally coupled to the LEDs. A particularly efficient heat coupling can be achieved in that the LED boards or a support element for the LED boards is designed angled and perpendicular to the support surface for the LEDs aligned leg of the support member or the board in a running in the longitudinal direction of the heat sink recess intervenes. That is, the heat sink also serves to hold the LEDs and heat dissipation is optimized.
Der Reflektor einer Beleuchtungseinheit ist dabei vorzugsweise in einer Ebene senkrecht zur Längsachse der Leuchte zumindest teilweise gekrümmt ausgeführt, um die gewünschte Lichtverteilung zu erzielen. In Längsrichtung der Leuchte wird dabei möglichst eine breite Lichtverteilung gewünscht, so dass hier der Reflektor zumindest über einen gewissen Längsabschnitt unverändert ausgeführt ist. Um trotz allem eine Entblendung auch in dieser Richtung zu erzielen, weist der Reflektor dann vorzugsweise an seinen Endbereichen geneigte Flächenabschnitte auf.The reflector of a lighting unit is preferably executed at least partially curved in a plane perpendicular to the longitudinal axis of the lamp in order to achieve the desired light distribution. In the longitudinal direction of the luminaire, a broad distribution of light is desired, so that here the reflector is designed unchanged, at least over a certain longitudinal section. In order to achieve a glare even in this direction, the reflector then preferably has inclined surface sections at its end regions.
Die Beleuchtungseinheiten sind vorzugsweise innerhalbe eines Gehäuses angeordnet, dessen Stirnseiten in etwa X-förmig ausgeführt sein können. Hierdurch weist die Leuchte ein besonders ansprechendes und interessantes Erscheinungsbild auf, wobei trotz allem optimale Lichtabstrahleigenschaften vorliegen.The lighting units are preferably arranged inside half of a housing whose end faces can be made approximately X-shaped. As a result, the lamp has a particularly appealing and interesting appearance, in spite of which optimal light emission properties are present.

Die in den Figuren allgemein mit dem Bezugszeichen 100 versehene erfindungsgemäße Leuchte dient wie bereits erwähnt in erster Linie dazu, beispielsweise in Geschäften oder Shops oberhalb von Regalen angeordnet zu werden und die jeweils schräg unterhalb der Leuchte befindlichen Regale auszuleuchten. Selbstverständlich könnte die Leuchte allerdings auch zu anderen Zwecken genutzt werden, beispielsweise um die Seitenwände eines länglichen Gangs oder dergleichen auszuleuchten.As already mentioned, the luminaire according to the invention, generally indicated by the
Die Leuchte 100 ist hierbei verhältnismäßig kompakt ausgeführt, erstreckt sich allerdings trotz allem entlang einer in
In der Praxis wird die Leuchte 100 mittig oberhalb zweier parallel zueinander verlaufender Regalreihen angeordnet werden und soll dann diese beiden Regalreihen beleuchten. Das heißt, wie in
Um diese gewünschte Lichtabstrahlcharakteristik zu erzielen und darüber hinaus auch die Möglichkeit zu eröffnen, die Ausrichtung der Maxima A, B zu beeinflussen, ist die Leuchte 100 mit speziellen Beleuchtungseinheiten ausgestattet, welche nachfolgend näher beschrieben werden sollen.In order to achieve this desired Lichtabstrahlcharakteristik and also to open the possibility to influence the orientation of the maxima A, B, the
Besonders gut erkennbar sind diese Beleuchtungseinheiten, welche allgemein mit dem Bezugszeichen 10 versehen sind, in der Schnittdarstellung gemäß
Als Leuchtmittel für jede der Beleuchtungseinheiten 10 kommen dabei LEDs 15 zum Einsatz, die jeweils auf einer oder mehreren Platinen 16 angeordnet sind. Das von den LEDs 15 emittierte Licht wird dabei nicht unmittelbar in die gewünschte Richtung abgegeben, sondern zunächst primär in eine entgegengesetzte Richtung, also zur Längsmittelebene der Leuchte 100 hin emittiert. Erst nachdem die Lichtstrahlen von einem Rückreflektor 20 reflektiert wurden, können diese die Beleuchtungseinheit 10 bzw. das Leuchtengehäuse 110 verlassen, wobei - wie in
Ein weiterer wesentlicher Bestandteil einer jeden Beleuchtungseinheit 10 besteht in einem Kühlkörper 25, mit dessen Hilfe die von den LEDs 15 während des Betriebs der Leuchte 100 generierte Wärme abgeführt werden soll. Hierfür ist eine effiziente thermische Kopplung zwischen LED-Platine 16 und Kühlkörper 25 von Vorteil, welche gemäß einer besonders bevorzugten Ausführungsform wie in der vergrößerten Darstellung von
Jede Beleuchtungseinheit 10 besteht also in erster Linie aus den LED-Leuchtmitteln 15 bzw. der LED-Platine 16, dem Rückreflektor 20 sowie dem zugehörigen Kühlkörper 25. Erfindungsgemäß ist nunmehr vorgesehen, dass die Beleuchtungseinheiten 10 verstellbar innerhalb des Gehäuses 110 der Leuchte 100 angeordnet sind. Wie hierbei in
Die Lichtabgabe einer einzelnen Beleuchtungseinheit 10 zeichnet sich also - im Schnitt senkrecht zur Längsachse I der Leuchte - durch ein einzelnes Strahlenbündel aus, dessen Ausrichtung durch Verschwenken der Beleuchtungseinheit 10 insgesamt verändert werden kann. Die Ausrichtung und Form des seitlich nach unten abgegebenen Strahlenbündels wird dabei durch die Krümmung des Reflektors 20 und die Ausrichtung der LEDs 15 erzielt. Dabei ist insbesondere vorgesehen, dass die LED-Platinen 16 nicht vollständig senkrecht, sondern stattdessen leicht geneigt ausgerichtet sind, derart, dass sich die Platinenunterkante näher an der Längsmittelebene der Leuchte 100 befindet als die entsprechende Oberkante, und zwar unabhängig vom Grad der Verschwenkung der zugehörigen Beleuchtungseinheit 10. Eine derartige Ausgestaltung hat sich als vorteilhaft herausgestellt, da in diesem Fall auch bei einem Blick von der Unterseite her die LEDs 15 nicht unmittelbar beobachtet werden können und dementsprechend keine Blendeffekte auftreten. Eine zusätzliche Abschirmung der LEDs 15 von der Unterseite her wird dabei dadurch erreicht, dass die Beleuchtungseinheit 10 eine außerhalb der LED-Platine 16 verlaufende, sich in etwa über die halbe Höhe erstreckende Seitenwand 11 aufweist, welche an ihrer Unterseite einen nach innen gerichteten, abgewinkelten Steg 12 aufweist. Dieser untere Endbereich der Seitenwand 11 definiert dabei gemeinsam mit dem Reflektor 20 eine Lichtaustrittsöffnung, über welche die Lichtabgabe der Beleuchtungseinheit 10 erfolgt.The light output of a
Bezüglich der Ausgestaltung der Reflektoren 20 ist zunächst anzumerken, dass diese in einer Ebene senkrecht zur Längsachse I ein verhältnismäßig enges Strahlenbündel erzeugen sollen, was wie erwähnt durch die Anordnung der LEDs 15 und die Krümmung des Reflektors 20 erzielt wird. In Längsrichtung hingegen soll eine möglichst breite Lichtverteilung vorliegen, um zu gewährleisten, dass trotz der verhältnismäßig kurzen Länge der Leuchte 100 ein größerer Abschnitt darunter liegender Regale beleuchtet werden kann. Dies wird zunächst einmal dadurch ermöglicht, dass der Reflektor 20 in einem mittleren Bereich in Längsrichtung gesehen unverändert bzw. translationsinvariant im Hinblick auf seine Reflexionsfläche 21 ausgeführt ist. An seinen beiden Endbereichen weist er allerdings geneigte Flächenabschnitte 22 auf, die insbesondere in den
Diese besondere Ausgestaltung der Reflektoren 20 führt auch dazu, dass sich bei einer Ansicht der Leuchte 100 von unten, wie sie in
Letztendlich weist also die erfindungsgemäße Leuchte ein äußerst interessantes Erscheinungsbild auch hinsichtlich des Bereichs, über den die Lichtabgabe erfolgt, auf. Trotz allem erfüllt die Leuchte hinsichtlich ihrer Lichtabstrahleigenschaften alle Anforderungen an eine Leuchte zur Beleuchtung beispielsweise von Regalreihen in Geschäften, wobei darüber hinaus auch eine Anpassung der Lichtverteilung vorgenommen werden kann, wodurch die Einsatz- bzw. Verwendungsmöglichkeiten deutlich verbessert werden.In the end, therefore, the luminaire according to the invention has an extremely interesting appearance, also with regard to the area over which the light is emitted. In spite of all, the luminaire fulfills all the requirements for a luminaire for illuminating, for example, rows of shelves in shops with regard to its light-emitting properties, wherein, moreover, it is also possible to adapt the light distribution, as a result of which the fields of use or use can be significantly improved.
