Die Erfindung löst diese Aufgabe durch die Merkmale des Anspruchs 1. Dadurch, dass zwischen den Reflexionsfacetten in Längsrichtung des Optikkörpers freie Bereiche vorgesehen sind, die nicht der Lichtumlenkung auf die Lichtaustrittsbereiche dienen, werden an der als Lichtaustrittsfläche ausgebildeten Vorderseite bei eingeschalteter Beleuchtung einzelne Lichtaustrittsbereiche beleuchtet, wobei sich zwischen den Lichtaustrittsbereichen Bereiche befinden, die mit den freien Bereichen korrespondieren und durch die im Wesentlichen kein Licht an die Umgebung abgegeben wird. Durch die Vorsehung sowohl von freien Bereichen als auch Reflexionsfacetten ergeben sich, insbesondere beim Zusammenbau mehrerer Lichtleitelemente zu einer Leuchte, besondere Gestaltungs- und Designmöglichkeiten. Aber auch bereits durch die Auswahl und das Verhältnis von Lichtaustrittsbereichen und nicht lichtabstrahlenden Bereichen an der Vorderseite des Optikkörpers kann ein neues Design aber auch eine differenzierte Signaloptik zum Beispiel bei Heckleuchten erzielt werden.The Invention solves This object is achieved by the features of claim 1. In that between the reflection facets in the longitudinal direction of the optic body free Areas are provided, not the light deflection to the light exit areas serve, are formed on the designed as a light exit surface front when the lighting is switched on, individual light emission areas illuminated, wherein there are areas between the light exit areas, which correspond to the free areas and through the essentially no light is emitted to the environment. By Providence, both of free areas as well as reflection facets arise, in particular when assembling several light guide to a lamp, special Design and design possibilities. But also already by the selection and the ratio of light emission areas and non-light emitting areas at the front of the optic body a new design but also a differentiated signal optics for example be achieved with rear lights.
Erfindungsgemäß ist vorgesehen, dass die der Vorderseite gegenüberliegende Seite mit den Reflexionsfacetten treppenförmig von einem Lichteintrittsende in Längsrichtung ansteigt, d. h. in Richtung auf die Vorderseite, unter Bildung der Reflexionsfacetten an den Treppenstufen. Die Reflexionsfacetten können dabei mit einer gewissen Krümmung beziehungsweise einem gewissen Radius ausgestattet sein. Neben treppenstufenförmigen Gestaltungen der Reflexionsfacetten ist es jedoch auch möglich, dass die Reflexionsfacetten einen geschwungenen, freiformartigen, beliebigen Verlauf aufweisen.According to the invention, it is provided that the opposite of the front Side with the reflection facets stepped from a light entry end longitudinal rises, d. H. towards the front, forming the Reflection facets on the stairs. The reflection facets can do this with a certain curvature or be equipped with a certain radius. In addition staircase-shaped designs of Reflection facets, however, it is also possible that the reflection facets have a curved, freeform, arbitrary course.
Dadurch, dass mehrere Optikelemente in Lichtabstrahlrichtung übereinander angeordnet sind, kann durch Betrieb beider oder lediglich einer Schicht der Lichtleitelemente eine jeweils eigene von außen sichtbare Lichtabstrahlung erzielt werden. Wird beispielsweise nur die oberste Schicht an Optikkörpern durch die Lichtquellen mit Licht versorgt, so wird eine erste Lichtverteilung abgestrahlt. Wird jedoch hingegen auch beispielsweise die untere Schicht beziehungsweise die weitere Schicht mit Licht versorgt, so ergeben die Lichtaustrittsbereiche der beiden Schichten zusammen für den Betrachter eine neue eigene Lichtcharakteristik.Thereby, that several optical elements in the light emission direction one above the other can be arranged by operating both or only one Layer of the light guide each own from the outside visible Light emission can be achieved. For example, only the top one Layer of optical bodies through the light sources supplied with light, so is a first light distribution radiated. However, however, for example, the lower Layer or the other layer supplied with light, Thus, the light exit areas of the two layers together for the Viewer a new own light characteristic.
Dadurch, dass die Übereinanderanordnung so ausgeführt wird, dass die beiden Optikkörper jeweils mit ihren aneinander angepassten Treppenformen aneinander gefügt sind, können platzsparend verschiedene Lichtfunktionen zusammen gefasst werden. Die Optikkörper der Lichtleitelemente sind also platzsparend so ineinander gefügt, dass sie mit ihrer treppenstufenförmigen Gestaltung gegeneinander anliegen.Thereby, that the superposition so accomplished that will be the two optic bodies each with their matching stair shapes together together are, can to save space, different lighting functions are combined. The optics body The light-guiding elements are so space-saving in such a way that you with your staircase-shaped Design against each other.
Darüber hinaus bietet eine entsprechende Anordnung die Möglichkeit, die Signalwirkung von Leuchten weiter zu verbessern, indem in der Leuchte beispielsweise ein Stoppzeichen für ein Bremslicht oder ein Pfeil für ein Blinklicht dargestellt ist, um so dem nachfolgenden Autofahrer noch deutlicher zu zeigen, was der vorherfahrende Autofahrer tun möchte.Furthermore An appropriate arrangement offers the possibility of signal effect of luminaires to further improve, for example, in the luminaire a stop sign for a stop light or an arrow for a flashing light is shown so as to follow the driver to show even more clearly what the preceding driver wants to do.
Dabei kann weiterhin vorgesehen sein, dass ein optisches Mittel zwischen Lichtquelle und den Reflexionsfacetten vorgesehen ist, dass das von der Lichtquelle abgestrahlte Licht annähernd parallelisiert oder bündelt. So kann bspw. eine Linse oder ein Reflektor vorgesehen sein, wobei sowohl die Linse als auch der Reflektor Teil des Optikkörpers sein können. Sie können jedoch auch als separate Bauteile ausgebildet sein. Durch die Linse oder den Reflektor wird dann parallelisiertes oder gebündeltes Licht in Längsrichtung des Optikkörpers durch diesen weiter geleitet, bis das Licht auf eine Reflexionsfacette trifft und in Richtung der Lichtaustrittsbereiche umgelenkt wird. Sofern zur Parallelisierung oder Bündelung des Lichts ein Reflektor eingesetzt wird, kann dieser als rotierte Parabel oder als Freiformreflektor gestaltet sein.there can be further provided that an optical means between Light source and the reflection facets is provided that the light emitted by the light source is approximately parallelized or bundled. So can be provided, for example, a lens or a reflector, wherein Both the lens and the reflector may be part of the optical body. she can but also be designed as separate components. Through the lens or the reflector is then parallelized or bundled Light in the longitudinal direction of the optic body passed through this until the light reaches a reflection facet meets and is deflected in the direction of the light exit areas. If for parallelization or bundling of light, a reflector can be used as a rotated parabola or as a free-form reflector be designed.
Hierbei kann insbesondere vorgesehen sein, dass die freien Bereiche durch die Unterseite des Optikkörpers gebildet werden, wobei dieser im Bereich der freien Bereiche parallel zur Lichtrichtung verläuft. Die Lichtquelle ist dabei insbesondere im Bereich eines Endes in Längsrichtung betrachtet des Optikkörpers angeordnet, so dass der gesamte Optikkörper über seine Länge der Lichtauskopplung dienen kann.In this case, it may in particular be provided that the free areas through the bottom of the Op be formed body, wherein this runs parallel to the light direction in the region of the free areas. The light source is arranged in particular in the region of one end in the longitudinal direction of the optical body, so that the entire optical body can serve over its length of light extraction.
Die Lichtquellen der einzelnen Lichtelemente können bei Bauweise nebeneinander alle auf der gleichen Seite der Optikkörper angeordnet sein, alternativ ist es jedoch auch möglich, einige Lichtquellen auf der einen Seite und andere auf der anderen Seite anzuordnen. Auch bei der Anordnung der Optikkörper übereinander ist es grundsätzlich möglich, die Lichtquellen auf einer Seite untereinander liegend vorzusehen, alternativ können auch die Lichtquellen eines Lichtleitelements auf der einen Seite und die des anderen Lichtleitelements auf der anderen Seite angeordnet sein. Schließlich können auch mehrere Lichtleitelemente über eine gemeinsame Lichtquelle mit Licht versorgt werden. Die Vorder- oder Lichtaustrittsseite der Optikkörper kann dabei zusätzliche bündelnde oder streuende optische Elemente aufweisen.The Light sources of the individual lighting elements can be next to each other in construction all be arranged on the same side of the optic body, alternatively but it is also possible some light sources on one side and others on the other side to arrange. Also in the arrangement of the optical body on top of each other, it is possible in principle, the Provide light sources on one side with each other, alternatively can also the light sources of a light guide on one side and those of the other light guide are arranged on the other side be. After all can also several light guide over a common light source can be supplied with light. The front or light exit side the optic body can be additional bundling or have scattering optical elements.
Schließlich kann insbesondere durch einen geschwungenen Verlauf der Reflexionsfacetten bei Betrachtung der Optikkörper von der Vorderseite her eine interessante optische Gestaltung auch bei ausgeschalteter Beleuchtung erzielt werden.Finally, can in particular by a curved course of the reflection facets when looking at the optic body from the front an interesting optical design as well be achieved with the lighting off.
