Description
Die vorliegende Erfindung betrifft ein optisches Element für Leuchtdioden oder Leuchtdioden-Cluster sowie eine Anordnung zur Lichtabgabe mit Leuchtdioden oder Leuchtdioden-Clustern und einem in Abstrahlrichtung vor den Leuchtdioden angeordnetem optischen Element.The present invention relates to an optical element for light-emitting diodes or light-emitting diode clusters and to an arrangement for emitting light with light-emitting diodes or light-emitting diode clusters and an optical element arranged in the emission direction in front of the light emitting diodes.
Bei länglichen LED-Leuchten waren bisher den einzelnen Leuchtdioden bzw. Leuchtdioden-Clustern meist einzelne optische Elemente zugeordnet, die die Lichtabgabe der Leuchte in gewünschter Weise steuern.In the case of oblong LED luminaires, individual optical elements or light-emitting diode clusters have hitherto mostly been associated with individual optical elements which control the light output of the luminaire in the desired manner.
Derart gestaltete längliche LED-Leuchten unterscheiden sich jedoch sowohl im Funktionsumfang als auch im Aussehen deutlich von länglichen Leuchten mit herkömmlichen Leuchten- bzw. Spiegelrastern und klassischen Leuchtmitteln, wie beispielsweise Leuchtstoffröhren. Ferner ist das individuelle Zuordnen von optischen Elementen zu den LEDs mit einem nicht geringen Aufwand verbunden.However, elongated LED luminaires designed in this way differ markedly in terms of functionality and appearance from elongated luminaires with conventional luminaire or mirror grids and classic illuminants, such as fluorescent tubes. Furthermore, the individual assignment of optical elements to the LEDs is associated with no great expense.
Der vorliegenden Erfindung liegt dementsprechend die Aufgabe zugrunde, ein optisches Element und eine Anordnung zur Lichtabgabe zu entwickeln, bei denen die Zuordnung der optischen Elemente zu den LEDs einfach und schnell möglich ist und zusätzlich einen vergleichbaren Funktionsumfang und ein ähnliches Aussehen, wie die bisher bekannten Leuchtenraster und länglichen Leuchten aufweisen.The present invention is accordingly an object of the invention to develop an optical element and an arrangement for light output, in which the assignment of the optical elements to the LEDs is easy and fast and in addition a comparable range of functions and a similar appearance, as the previously known luminaire grid and have elongated lights.
Die Aufgabe wird durch ein optisches Element gemäß Anspruch 1 und durch eine Anordnung zur Lichtabgabe gemäß Anspruch 11 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der abhängigen Ansprüche.The object is achieved by an optical element according to claim 1 and by an arrangement for emitting light according to claim 11. Advantageous developments of the invention are the subject of the dependent claims.
Erfindungsgemäß ist vorgesehen, ein optisches Element für in Längsrichtung hintereinander angeordnete einzelne Leuchtdioden oder Leuchtdioden-Cluster einzusetzen, dass ähnlich wie ein klassisches Leuchtenraster zwei längliche Seitenreflektoren und quer zwischen den Seitenreflektoren angeordnete Querreflektoren aufweist. Hierbei ist insbesondere vorgesehen, dass der Abstand der Querreflektoren zueinander dem Abstand zweier benachbarter Leuchtdioden oder Leuchtdioden-Cluster entspricht.According to the invention, it is provided to use an optical element for longitudinally successively arranged individual light-emitting diodes or light-emitting diode clusters, that similar to a classical light grid two elongated ones Side reflectors and arranged transversely between the side reflectors transverse reflectors. In this case, provision is made in particular for the spacing of the transverse reflectors from one another to correspond to the distance between two adjacent light-emitting diodes or light-emitting diode clusters.
Des Weiteren ist auch eine Anordnung zur Lichtabgabe vorgesehen, die ein erfindungsgemäßes optisches Element und mehrere in Längsrichtung hintereinander angeordnete einzelne Leuchtdioden oder Leuchtdioden-Cluster aufweist. Das optische Element ist hierbei in Abstrahlrichtung vor den einzelnen Leuchtdioden oder Leuchtdioden-Clustern angeordnet, wobei zwischen jedem Querreflektor eine Leuchtdiode oder ein Leuchtdioden-Cluster angeordnet ist.Furthermore, an arrangement for emitting light is provided which has an optical element according to the invention and a plurality of individual light-emitting diodes or light-emitting diode clusters arranged one behind the other in the longitudinal direction. The optical element is in this case arranged in the emission direction in front of the individual light-emitting diodes or light-emitting diode clusters, wherein a light-emitting diode or a light-emitting diode cluster is arranged between each transverse reflector.
Vorteilhafterweise können die Querreflektoren des optischen Elements im Wesentlichen V-förmig ausgebildet sein, wobei die den Leuchtdioden oder Leuchtdioden-Clustern zugewandte Fläche der Querreflektoren vorzugsweise dieselbe Krümmung wie die der Seitenreflektoren aufweist, wodurch sich eine relativ parallele Lichtabgabe ergibt, die in vielen Anwendungsgebieten besonders gewünscht ist.Advantageously, the transverse reflectors of the optical element may be formed substantially V-shaped, wherein the light emitting diodes or light-emitting diode clusters facing surface of the transverse reflectors preferably has the same curvature as that of the side reflectors, resulting in a relatively parallel light output, which is particularly desirable in many applications is.
Die Krümmung der Seiten- und Querreflektoren kann aber auch je nach gewünschter Abstrahlcharakteristik völlig unterschiedlich ausgebildet sein. Zusätzlich kann hierbei auch noch vorgesehen sein, dass die Seiten- und Querreflektoren in unterschiedlichen Bereichen des optischen Elements unterschiedlich ausgebildet sind. Hierdurch entsteht die Möglichkeit, dass eine längliche LED-Leuchte mit dem erfindungsgemäßen optischen Element mehrere Beleuchtungsaufgaben gleichzeitig erfüllen kann.The curvature of the side and transverse reflectors can also be designed completely differently depending on the desired radiation characteristic. In addition, it can also be provided here that the lateral and transverse reflectors are designed differently in different regions of the optical element. This creates the possibility that an elongate LED light with the optical element according to the invention can fulfill several lighting tasks simultaneously.
Im Gegensatz zu einem klassischen Leuchtenraster dienen bei der erfindungsgemäßen Lösung die Querreflektoren nicht nur lediglich der Entblendung, sondern können zusätzlich auch aufgrund der Punktförmigkeit der Leuchtdioden ähnlich wie die Seitenreflektoren zur gezielten Strahlformung eingesetzt werden.In contrast to a classic luminaire grid, in the solution according to the invention, the transverse reflectors not only serve only for glare control but, in addition, can also be used for targeted beam shaping, similar to the point shape of the light-emitting diodes, similar to the side reflectors.
Hierdurch ist eine gezielte Lichtlenkung nicht nur quer zur Leuchte mit Hilfe der Seitenreflektoren, sondern auch entlang der Leuchte durch Verwendung der Querreflektoren möglich.As a result, a targeted light control not only across the lamp using the side reflectors, but also along the lamp by using the transverse reflectors is possible.
Grundsätzlich ist aber anzumerken, dass das optische Element, wie auch ein klassisches Leuchtenraster, bauartbedingt weiterhin der Entblendung dient.Basically, however, it should be noted that the optical element, as well as a classic lighting grid, due to the design continues to serve glare.
Das erfindungsgemäße optische Element unterscheidet sich des Weiteren von einem klassischen Leuchtenraster durch die unterschiedlichen Abmessungen. So kann vorgesehen sein, dass das Verhältnis zwischen dem Abstand der Seitenreflektoren und dem Abstand der Querreflektoren in etwa 1:1 ist, wobei das Verhältnis zwischen der Höhe der Seitenreflektoren und dem Abstand der Seitenreflektoren zwischen 1:1 und 1:1,5 liegen kann und das Verhältnis zwischen der Höhe der Querreflektoren und dem Abstand der Querreflektoren ebenfalls zwischen 1:1 und 1:1,5 liegen kann. Der Abstand zwischen den Querreflektoren ergibt sich hierbei insbesondere durch den Abstand zweier benachbarter Leuchtdioden oder Leuchtdioden-Cluster, wobei die Leuchtdioden oder Leuchtdioden-Cluster vorteilhafterweise jeweils mittig zwischen den Querreflektoren und Seitenreflektoren angeordnet sind. Durch die im Verhältnis große Höhe der Seiten- und Querreflektoren wird eine gute Lichtbündelung erzielt.The optical element according to the invention further differs from a classic luminaire grid by the different dimensions. Thus, it can be provided that the ratio between the distance of the side reflectors and the distance of the transverse reflectors is approximately 1: 1, wherein the ratio between the height of the side reflectors and the distance between the side reflectors can be between 1: 1 and 1: 1.5 and the ratio between the height of the transverse reflectors and the distance of the transverse reflectors may also be between 1: 1 and 1: 1.5. The distance between the transverse reflectors results here in particular by the distance between two adjacent light-emitting diodes or light-emitting diode clusters, wherein the light-emitting diodes or light-emitting diode clusters are advantageously arranged in each case centrally between the transverse reflectors and side reflectors. Due to the relatively high height of the side and transverse reflectors, a good light bundling is achieved.
Durch das erfindungsgemäße optische Element wird nun in einfacher Weise eine Beeinflussung der Lichtabgabe der Leuchtdioden oder Leuchtdioden-Cluster erzielt, wofür nun nicht mehr für jede Leuchtdiode bzw. für jedes Leuchtdioden-Cluster ein einzelnes optisches Element erforderlich ist.By means of the optical element according to the invention, an influencing of the light output of the light-emitting diodes or light-emitting diode clusters is now achieved in a simple manner, for which a single optical element is no longer required for each light-emitting diode or for each light-emitting diode cluster.
