Description

Anordnung zur Lichtabgabe  Arrangement for emitting light
Die vorliegende Erfindung betrifft eine Anordnung zur Lichtabgabe mit mindestens einer LED-Lichtquelle und mindestens einer in Lichtabstrahlrichtung vor der LED- Lichtquelle angeordneten ersten Linse. The present invention relates to an arrangement for emitting light with at least one LED light source and at least one first lens arranged in the light emission direction in front of the LED light source.
Bei länglichen Leuchten bzw. Anordnungen zur Lichtabgabe, die beispielsweise im gewerblichen Bereich Anwendung finden, wurden bisher häufig Leuchtstofflampen als Lichtquellen eingesetzt. Die fortschreitende Entwicklung von LEDs führt nun immer mehr dazu, dass beispielsweise Leuchtstofflampen durch entsprechende LEDs ersetzt werden. Dies ergibt sich zum einen daraus, dass LED-Lichtquellen erhebliche Vorteile bzgl. der Lebensdauer und Energieeffizienz im Vergleich zu herkömmlichen In the case of elongated luminaires or arrangements for emitting light, which are used, for example, in the commercial sector, fluorescent lamps have hitherto frequently been used as light sources. The progressive development of LEDs now leads more and more to the fact that, for example, fluorescent lamps are replaced by corresponding LEDs. This results, on the one hand, from the fact that LED light sources have considerable advantages in terms of lifetime and energy efficiency compared to conventional ones
Leuchtmitteln aufweisen. Zum anderen sind die mit Hilfe von LEDs erzielbarenHave bulbs. On the other hand, they are achievable with the help of LEDs
Lichtstärken mittlerweile ausreichend hoch, sodass LED-Lichtquellen ohne Weiteres klassische Lichtquellen wie beispielsweise Leuchtstofflampen ersetzen können. Luminous intensities are now sufficiently high that LED light sources can easily replace conventional light sources such as fluorescent lamps.
Um nun eine gewünschte Abstrahlcharakteristik der gesamten Anordnung zu erreichen, ist beispielsweise vorgesehen, dass den LED-Lichtquellen Linsen zugeordnet sind, die in Abstrahlrichtung vor den LED-Lichtquellen angeordnet werden. Mehrere derartiger Linsen sind hierbei zu einem länglichen optischen Element zusammengefügt, wobei vorzugsweise jeder LED-Lichtquelle genau eine Linse des optischen Elements zugeordnet ist. In order to achieve a desired radiation characteristic of the entire arrangement, it is provided, for example, that the LED light sources are associated with lenses which are arranged in the emission direction in front of the LED light sources. Several such lenses are in this case joined together to form an elongated optical element, wherein preferably each LED light source is associated with exactly one lens of the optical element.
In Figur 1 ist eine derartige Anordnung zur Lichtabgabe 1 gezeigt, die ein Gehäuse 3 mit einer Lichtaustrittsöffnung aufweist, wobei in dem Gehäuse 3 die LED- Lichtquellen 4 angeordnet sind und die zu dem optischen Element 2 In Figure 1, such a device for light emission 1 is shown, which has a housing 3 with a light exit opening, wherein in the housing 3, the LED light sources 4 are arranged and the to the optical element. 2
zusammengefügten Linsen 6 das Gehäuse 3 in Lichtabstrahlrichtung verschließen. In Figur 3 ist ein optisches Element 2 gezeigt, das aus mehreren Linsen 6 besteht. assembled lenses 6, the housing 3 in the light emission direction close. FIG. 3 shows an optical element 2 which consists of a plurality of lenses 6.
Derartige optische Elemente 2 werden hierbei zumeist im Spritzgussverfahren hergestellt. Aus Figur 2 geht die Lichtstärkeverteilungskurve der in Figur 3 gezeigten Linsen 6 bzw. des optischen Elements 2 und dementsprechend auch der Anordnung zur Lichtabgabe 1 hervor, wobei die dort dargestellte Kurve den Werten in der C0/C180 Ebene, also in Querrichtung zu dem in Figur 3 gezeigten optischen Element 2 bzw. der Anordnung zur Lichtabgabe 1, entspricht. Die in Fig. 2 gezeigte Such optical elements 2 are in this case usually produced by injection molding. FIG. 2 shows the luminous intensity distribution curve of the lenses 6 or of the optical element 2 shown in FIG. 3 and accordingly also of the arrangement for emitting light 1, wherein the curve shown there corresponds to the values in the C0 / C180 plane, ie in the transverse direction to that shown in FIG 3 and the light emitting device 1, respectively. The shown in Fig. 2
Lichtstärkeverteilungskurve weist hierbei zwei voneinander getrennte Flügel auf, die jeweils einen Spitzenbereich bei 15° und daran beidseits anschließende Luminous intensity distribution curve in this case has two separate wings, each having a tip region at 15 ° and adjoining both sides
Flankenbereiche, in denen die Lichtstärke auf einen deutlich geringeren Wert als in dem Spitzenbereich abfällt, aufweisen, wobei eine der Flanken zu dem Winkelbereich um 0° hin abfällt. Der Winkel zwischen den beiden Spitzenbereichen der Flügel entspricht hierbei dem Öffhungs- bzw. Abstrahlwinkel des von der ersten Linse abgegebenen Lichts. Dementsprechend weist hier der Öffhungs- bzw. Abstrahlwinkel einen Wert von 30° auf. Eine derartige Lichtstärkeverteilung ist beispielsweise dann von Vorteil, wenn eine entsprechende Anordnung zur Lichtabgabe 1 entlang eines Gangs angeordnet werden soll, der jeweils rechts und links Regale aufweist, die entsprechend durch die Flank regions in which the light intensity drops to a much lower value than in the tip region, wherein one of the flanks falls to the angle range by 0 °. The angle between the two tip regions of the wings corresponds to the opening or emission angle of the light emitted by the first lens. Accordingly, the opening or emission angle here has a value of 30 °. Such a luminous intensity distribution is advantageous, for example, when a corresponding arrangement for emitting light 1 is to be arranged along a corridor, which has shelves each on the right and left, which are correspondingly provided by the
Anordnung zur Lichtabgabe 1 beleuchtet werden sollen. Arrangement for emitting light 1 to be illuminated.
Der aus Figur 2 ersichtliche halbe Öffhungs- bzw. Abstrahlwinkel von 15° ist zusätzlich auch noch einmal in Figur 1 eingezeichnet. Dieser Öffhungs- bzw. The apparent from Figure 2 half opening or beam angle of 15 ° is also shown again in Figure 1. This opening or
Abstrahlwinkel ergibt sich durch die Ausgestaltung der Linsen 6, weshalb dieser Öffhungs- bzw. Abstrahlwinkel durch eine entsprechende Änderung der Bauform der Linsen 6 verändert werden kann, falls ein anderer Öffhungs- bzw. Abstrahlwinkel der Anordnung zur Lichtabgabe 1 gewünscht ist. Beam angle results from the design of the lenses 6, which is why this Öffhungs- or beam angle can be changed by a corresponding change in the design of the lenses 6, if a different Öffhungs- or radiation angle of the arrangement for light output 1 is desired.
Hierbei besteht aber nun das Problem, dass für eine derartige Änderung des Öffnungsbzw. Abstrahlwinkels, das gesamte optische Element ausgetauscht werden muss, was entsprechend hohe Kosten verursacht. Zusätzlich entstehen auch erhebliche Kosten durch die Herstellung weiterer optischer Elemente im Spritzgussverfahren, da für jede alternative Ausführungsform eigene Werkzeuge bzw. Gussformen hergestellt werden müssen, die zu hohen Kosten führen. Der vorliegenden Erfindung liegt dementsprechend die Aufgabe zu Grunde, die oben skizzierte Anordnung zur Lichtabgabe derart weiterzuentwickeln, dass der Öffnungsbzw. Abstrahlwinkel der Anordnung zur Lichtabgabe verändert werden kann, ohne dass die Linsen bzw. das optische Element ausgetauscht werden müssen. But here is the problem that for such a change of the Öffnungsbzw. Beam angle, the entire optical element must be replaced, which causes correspondingly high costs. In addition, considerable costs are incurred by the production of additional optical elements in the injection molding process, since for each alternative embodiment own tools or molds must be produced, which lead to high costs. Accordingly, the present invention is based on the object of further developing the above-outlined arrangement for emitting light such that the Öffnungsbzw. Beam angle of the arrangement for emitting light can be changed without the lenses or the optical element must be replaced.
Die Aufgabe wird durch eine Anordnung zur Lichtabgabe gemäß Anspruch 1 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der abhängigen The object is achieved by an arrangement for emitting light according to claim 1. Advantageous developments of the invention are the subject of the dependent

Zusätzlich kann die zweite Linse derart ausgebildet und vor der ersten Linse angeordnet sein, dass durch die zweite Linse der Öffnungs- bzw.

Alternativ könnte die zweite Linse auch derart ausgebildet und vor der ersten Linse angeordnet sein, dass durch die zweite Linse der Öffnungs- bzw. Abstrahlwinkel des von der ersten Linse abgegebenen Lichts vergrößert wird. Durch die zweite Linse ist es somit nunmehr möglich, dass der Öffnungs- bzw. In addition, the second lens may be formed and arranged in front of the first lens such that the opening or emission angle of the light emitted by the first lens is reduced by the second lens. Alternatively, the second lens could also be designed and arranged in front of the first lens such that the opening or emission angle of the light emitted by the first lens is increased by the second lens. By the second lens, it is now possible that the opening or
Abstrahlwinkel der Lichtabgabe der gesamten Anordnung zur Lichtabgabe verändert werden kann, ohne die erste Linse austauschen zu müssen, wobei die Lichtabgabe in der C90/C270-Ebene insbesondere durch die erste Linse beeinfiusst wird. Wie bereits oben erläutert, kann auch hier vorgesehen sein, dass die Anordnung zur Lichtabgabe mehrere LED-Lichtquellen und mehrere erste Linsen aufweist, wobei die ersten Linsen zu einem optischen Element zusammengefügt sind. Zusätzlich kann auch vorgesehen sein, dass jeder LED-Lichtquelle jeweils genau eine erste Linse des optischen Elements zugeordnet ist. Des Weiteren kann ebenfalls vorgesehen sein, dass die Anordnung zur Lichtabgabe ein Gehäuse mit einer Lichtaustrittsöffnung aufweist, wobei in dem Gehäuse die mindestens eine LED-Lichtquelle angeordnet ist, und die mindestens eine erste Linse das Gehäuse in Lichtabstrahlrichtung verschließt.  Beam angle of the light output of the entire arrangement for light emission can be changed without having to replace the first lens, the light output in the C90 / C270 level is particularly affected by the first lens.

This light intensity distribution is suitable, for example, for shops, where shelves along the corridors left and right are arranged relatively close to the aisles, which are to be particularly illuminated by appropriate arrangements for light output 1.
An der Oberseite des Gehäuses ist des Weiteren bei der Anordnung zur Lichtabgabe 1 noch eine Vorrichtung 5 vorgesehen, die eine mechanische Befestigung der At the top of the housing is further provided in the arrangement for emitting light 1, a device 5, which is a mechanical attachment of
Anordnung zur Lichtabgabe 1 an einer Tragschiene ermöglicht und ferner innerhalb der Tragschiene verlaufende Leitungen kontaktiert. Erfindungsgemäß ist nun vorgesehen, dass in Lichtabstrahlrichtung vor der ersten Linse 6 eine zweite Linse 7, 8 zur Beeinflussung des von der ersten Linse abgegebenen Lichts angeordnet ist. In den Figuren 4 und 6 sind hierzu zwei erfindungsgemäße Ausführungsbeispiele dargestellt, wobei die in den Figuren 4 und 6 gezeigten Arrangement for light emission 1 allows a support rail and also contacted within the support rail extending lines. According to the invention, it is now provided that in the light emission direction in front of the first lens 6, a second lens 7, 8 is arranged for influencing the light emitted by the first lens. In the figures 4 and 6 for this purpose two embodiments of the invention are shown, wherein the shown in Figures 4 and 6
Anordnungen zur Lichtabgabe 1 ansonsten jeweils dieselben Bauteile wie die Arrangements for light emission 1 otherwise the same components as the
Anordnung zur Lichtabgabe 1 in Figur 1 aufweisen. In Figur 4 ist hierbei eine entsprechende Ausgestaltungsvariante gezeigt, bei der eine zweite Linse 7 derart ausgebildet und vor der ersten Linse 6 angeordnet ist, dass durch die zweite Linse 7 der Öffnungs- bzw. Abstrahlwinkel des von der ersten Linse 6 abgegebenen Lichts verkleinert bzw. verringert wird, wobei bei der in Figur 4 gezeigten Variante der Öffnungs- bzw. Abstrahlwinkel gegen 0° geht. Arrangement for emitting light 1 in Figure 1 have. FIG. 4 shows a corresponding embodiment variant in which a second lens 7 is designed in such a way and arranged in front of the first lens 6 that the opening or emission angle of the light emitted by the first lens 6 is reduced or reduced by the second lens 7. is reduced, wherein in the variant shown in Figure 4, the opening or beam angle goes to 0 °.
Die entsprechende Lichtstärkeverteilungskurve bzw. Lichtabstrahlcharakteristik zu der in Figur 4 gezeigten Anordnung zur Lichtabgabe 1 ist in Figur 5 gezeigt. Dieser ist im Gegensatz zu der in Figur 2 gezeigten Lichtstärkeverteilungskurve, der zwei The corresponding luminous intensity distribution curve or light emission characteristic for the light emission arrangement 1 shown in FIG. 4 is shown in FIG. This is in contrast to the light intensity distribution curve shown in Figure 2, the two
Spitzenbereiche bei jeweils 15° zu entnehmen sind, lediglich ein Spitzenbereich bei 0° zu entnehmen, wodurch sich ein Öffnungs- bzw. Abstrahlwinkel von 0° ergibt. Peak areas are to be taken at 15 °, only a tip area at 0 ° to remove, resulting in an opening or beam angle of 0 °.
Hierdurch eignet sich die Anordnung zur Lichtabgabe 1 aus Figur 4 beispielsweise für die Beleuchtung von Gängen in Verkaufsläden, an denen keine Regale links und rechts angeordnet sind. As a result, the arrangement for emitting light 1 from Figure 4, for example, for the illumination of aisles in shops, where no shelves are arranged left and right.
Wie Figur 4 zu entnehmen ist, weist die zweite Linse 7 ein zur Mitte spitz zulaufendes Dreieck auf, wobei das Dreieck an der der ersten Linse 6 abgewandten Seite der zweiten Linse 7 angeordnet ist und die Spitze des Dreiecks von der ersten Linse 6 bzw. der LED-Lichtquelle 4 weg zeigt. Diese Dreiecksform bricht das von der ersten Linse 6 mit einem Öffnungs- bzw. Abstrahlwinkel von 15° abgegebene Licht derart bzw. lenkt es derart um, dass der Öffnungswinkel bzw. Abstrahlwinkel danach im As can be seen in FIG. 4, the second lens 7 has a triangle which tapers towards the center, wherein the triangle is arranged on the side of the second lens 7 facing away from the first lens 6, and the tip of the triangle is arranged on the first lens 6 or LED light source 4 pointing away. This triangular shape breaks the light emitted by the first lens 6 with an opening or emission angle of 15 ° in such a way or diverts it such that the opening angle or emission angle thereafter
Wesentlichen einen Wert von 0° aufweist. Substantially has a value of 0 °.
Eine derartige Ausgestaltung ist wie bereits erläutert beispielweise dann Such an embodiment is as already explained, for example, then
wünschenswert, wenn entlang eines Gangs keine Regale mehr seitlich angeordnet sind und dementsprechend nur noch der Gang beleuchtet werden soll oder wenn hohe Regale zu beleuchten sind. Hierbei ist es nun aber nicht mehr notwendig, dass bei einer Anordnung zur Lichtabgabe das gesamte optische Element ausgetauscht werden muss. Vielmehr ist es ohne Weiteres möglich, dass eine Anordnung zur Lichtabgabe mit einem entsprechenden optischen Element installiert wird und dann entsprechend den örtlichen Bedingungen nachträglich zweite Linsen der Anordnung zur Lichtabgabe zugeordnet werden. So ist es beispielsweise denkbar, dass bei einer Umgestaltung von Gängen in Einkaufsläden, bei denen bisher normale Regale seitlich entlang des Gangs angeordnet waren und dementsprechend beispielsweise Anordnungen zur Lichtabgabe 1 wie in Figur 1 gezeigt, verwendet worden sind, nach einer Umgestaltung, bei der die Regale entfernt oder entsprechend hohe Regale angeordnet worden sind, nicht die gesamte Anordnung zur Lichtabgabe ausgetauscht werden muss bzw. dass optische Element 2 sondern lediglich zweite Linsen 7 der Anordnung zur Lichtabgabe 1 zugeordnet werden müssen. desirable if no shelves are arranged laterally along a corridor and accordingly only the corridor should be illuminated or if tall shelves are to be illuminated. Here it is no longer necessary that at a Arrangement for light emission, the entire optical element must be replaced. Rather, it is readily possible that an arrangement for emitting light is installed with a corresponding optical element and then assigned according to the local conditions subsequently second lenses of the arrangement for emitting light. So it is conceivable, for example, that in a redesign of aisles in shops, where previously normal shelves were arranged laterally along the aisle and accordingly, for example, arrangements for light emission 1 as shown in Figure 1, have been used after a refactoring, in which the Shelves removed or appropriately high shelves have been arranged, not the entire assembly must be replaced to emit light or that optical element 2 but only second lenses 7 of the light emitting device 1 must be assigned.
Das in Figur 4 gezeigte Ausführungsbeispiel zeigt eine Variante, bei der der Öffnungs- bzw. Abstrahlwinkel im Wesentlichen 0° beträgt. Denkbar wäre aber auch, dass der Öffnungs- bzw. Abstrahlwinkel nicht so stark bzw. noch stärker verkleinert wird. The embodiment shown in Figure 4 shows a variant in which the opening or emission angle is substantially 0 °. It would also be conceivable, however, that the opening or emission angle is not reduced so much or even more strongly.
Im Gegensatz zu dem in Figur 4 gezeigten Ausführungsbeispiel, in dem durch die zweite Linse 7 der Öffnungs- bzw. Abstrahlwinkel verkleinert wird, ist bei dem in Figur 6 gezeigten Ausführungsbeispiel eine zweite Linse 8 vor der ersten Linse 6 vorgesehen, durch die der Öffnungs- bzw. Abstrahlwinkel des von der ersten Linse abgegebenen Lichts vergrößert wird. Wie den Figuren 6 und 7 zu entnehmen ist, ist die zweite Linse 8 hierbei derart ausgestaltet, dass der halbe Öffnungs- bzw. In contrast to the exemplary embodiment shown in FIG. 4, in which the opening or emission angle is reduced by the second lens 7, in the embodiment shown in FIG. 6 a second lens 8 is provided in front of the first lens 6, through which the opening or radiation angle of the light emitted from the first lens is increased. As can be seen from Figures 6 and 7, the second lens 8 is in this case designed such that half the opening or
Abstrahlwinkel einen Wert von ca. 30° aufweist. Der Figur 7 kann hier wiederum die Lichtstärkeverteilungskurve der in Figur 6 gezeigten Anordnung zur Lichtabgabe 1 entnommen werden, wobei im Vergleich zu der Lichtstärkeverteilungskurve in Figur 2 zu erkennen ist, dass sich die beiden Spitzbereiche nunmehr bei 30° befinden und somit Öffnungs- bzw. Ab strahl winkel einen Wert von 60° aufweist. Dementsprechend hat diese Anordnung zur Lichtabgabe 1 eine Lichtstärkeverteilung, die, wie die Lichtstärkeverteilung der in Figur 1 gezeigten Anordnung zur Lichtabgabe 1, zwei im Wesentlichen symmetrische Flügel zeigt. Beam angle has a value of about 30 °. In FIG. 7, the light intensity distribution curve of the light emission arrangement 1 shown in FIG. 6 can again be taken from FIG. 2, it being apparent from FIG. 2 that the two pointed regions are now at 30 ° and thus open or closed beam angle has a value of 60 °. Accordingly, this arrangement for light emission 1 has a light intensity distribution which, like the light intensity distribution of the light emission arrangement 1 shown in FIG. 1, shows two essentially symmetrical wings.
Wie der Figur 6 zu entnehmen ist, weist die zweite Linse 8 eine weit geöffnete V-Form an der der ersten Linse 6 abgewandten Seite auf, wobei die Spitze der V-Form in Richtung der ersten Linse 6 zeigt. Diese im Wesentlichen das Gegenstück zur Form der zweiten Linse 7 aus Figur 4 bildende Form bricht das von der ersten Linse 6 abgegebene Licht derart bzw. lenkt es um, dass der von der ersten Linse vorgegebene halbe Öffnungs- bzw. Abstrahlwinkel von 15° auf 30° vergrößert wird. As can be seen from FIG. 6, the second lens 8 has a wide-open V-shape on the side facing away from the first lens 6, wherein the tip of the V-shape in FIG Direction of the first lens 6 shows. This form, which essentially forms the counterpart to the shape of the second lens 7 from FIG. 4, breaks or redirects the light emitted by the first lens 6 in such a way that the half-opening or emission angle predetermined by the first lens increases from 15 ° to 30 ° ° is increased.
Durch die Vergrößerung des Öffnungs- bzw. Abstrahlwinkels ist es nunmehr möglich, dass eine erfindungsgemäße Anordnung zur Lichtabgabe beispielweise auch zur Beleuchtung von Regalen bei breiteren Gängen oder bei niedrigeren Abhänghöhen der Decken in Verkaufsräumen eingesetzt werden kann. So wäre es des Weiteren auch denkbar, dass beispielsweise bei einer Umgestaltung eines Verkaufsraums, bei dem ein Gang verbreitert wird oder die Abhänghöhe der Decke niedriger gemacht wird, die bisher eingesetzte Anordnung zur Lichtabgabe 1, wie beispielsweise in Figur 1 gezeigt, durch die einfache Anbringung der zweiten Linse 8 angepasst wird und damit gewährleistet ist, dass auch nach der Umgestaltung der Verkaufsräume die Regale entsprechend gut ausgeleuchtet werden. By increasing the opening or beam angle, it is now possible that an arrangement according to the invention can be used for light output, for example, to illuminate shelves in wider aisles or lower heights of ceilings in sales rooms. So it would also be conceivable that, for example, in a redesign of a sales room in which a corridor is widened or the suspension height of the ceiling is made lower, the previously used arrangement for light emission 1, as shown for example in Figure 1, by the simple attachment the second lens 8 is adjusted and thus ensures that even after the redesign of the sales rooms, the shelves are well illuminated accordingly.
Wie bereits bei der in Figur 4 gezeigten Ausführungsform ist auch bei der in Figur 6 gezeigten Ausführungsform zu erwähnen, dass die zweite Linse 8 auch so ausgestaltet sein kann, dass eine stärkere bzw. geringere Vergrößerung des Öffnungs- bzw. As in the case of the embodiment shown in FIG. 4, it should also be mentioned in the embodiment shown in FIG. 6 that the second lens 8 can also be designed such that a greater or lesser enlargement of the opening or closing
Abstrahlwinkels stattfindet. Beam angle takes place.
Insgesamt ist zur vorliegenden Erfindung anzumerken, dass durch diese ein durch eine erste Optik vorgegebener Öffnungs- bzw. Abstrahlwinkel durch eine zweite vor der ersten Optik angeordnete Optik verändert werden kann, wobei in der C90/C270-Ebene eine Beeinflussung (Entblendung, Leuchtdichtereduzierung, Einhaltung UGR) insbesondere durch die erste Linse erfolgt und die zweite Linse hierauf kaum Einfluss nimmt. Overall, it should be noted to the present invention that this can be changed by a predetermined by a first optics opening or emission angle by a second arranged in front of the first optics, wherein in the C90 / C270 level influencing (glare, luminance reduction, compliance UGR) takes place in particular by the first lens and the second lens hardly influences it.
