Abstract
Description
Die Erfindung betrifft eine Optikscheibe für eine Heckleuchte, mit einer einer Lichtquelle zugewandten Rückseite und einer der Lichtquelle abgewandten Vorderseite, und mit optischen Mitteln zum Streuen von Licht. Die Erfindung betrifft des Weiteren eine Heckleuchte mit einer derartigen Optikscheibe. Die Erfindung betrifft darüber hinaus ein Kraftfahrzeug mit einer derartigen Heckleuchte. The invention relates to an optical disk for a rear light, with a rear side facing a light source and a front side facing away from the light source, and with optical means for diffusing light. The invention further relates to a tail light with such an optical disk. The invention also relates to a motor vehicle with such a tail light.
Aus der deutschen Offenlegungsschrift
Aufgabe der Erfindung ist es, die optische Wirkung von Heckleuchten weiter zu verbessern. The object of the invention is to further improve the optical effect of tail lights.
Die Aufgabe ist bei einer Optikscheibe für eine Heckleuchte, mit einer einer Lichtquelle zugewandten Rückseite und einer der Lichtquelle abgewandten Vorderseite, und mit optischen Mitteln zum Streuen von Licht, dadurch gelöst, dass die Optikscheibe auf der Vorderseite und auf der Rückseite mit optischen Mitteln zum Streuen von Licht versehen ist. Dadurch können besondere optische Effekte erzielt werden, die mit herkömmlichen Optikscheiben nicht möglich sind. The object is in an optical disc for a rear light, with a light source facing back and a light source facing away from the front, and optical means for diffusing light, achieved in that the optical disc on the front and on the back with optical means for scattering provided by light. As a result, special optical effects can be achieved that are not possible with conventional optical discs.
Die oben angegebene Aufgabe ist bei einer Heckleuchte gemäß dem Oberbegriff des Anspruchs 1 alternativ oder zusätzlich dadurch gelöst, dass die optischen Mitteln zum Streuen von Licht mindestens einen Lichtdurchtrittsbereich aufweisen, in welchem die optischen Mittel zum Streuen von Licht durchbrochen beziehungsweise nicht vorhanden sind. Der Lichtdurchtrittsbereich ermöglicht einen ungehinderten Durchtritt von Licht, insbesondere ohne eine Streuung, wie sie durch die optischen Mittel zum Streuen von Licht verursacht wird. Dadurch können besonders vorteilhaft lichttechnische Werte erreicht werden, die mit herkömmlichen Optikscheiben nicht möglich sind. Der Lichtdurchtrittsbereich ist vorzugsweise als Schlitz ausgeführt. The above-mentioned object is alternatively or additionally solved in a tail lamp according to the preamble of claim 1 in that the optical means for diffusing light have at least one light passage area in which the optical means for diffusing light are broken or not present. The light passage region allows unimpeded passage of light, especially without scattering caused by the optical means for diffusing light. As a result, photometric values which are not possible with conventional optical disks can be achieved particularly advantageously. The light passage region is preferably designed as a slot.
Ein weiteres bevorzugtes Ausführungsbeispiel der Optikscheibe ist dadurch gekennzeichnet, dass nur die optischen Mittel zum Streuen von Licht auf der Vorderseite der Optikscheibe mindestens einen Lichtdurchtrittsbereich aufweisen. Gegebenenfalls auf der Rückseite der Optikscheibe vorgesehene optische Mittel zum Streuen von Licht können ohne Lichtdurchtrittsbereich ausgeführt werden. A further preferred exemplary embodiment of the optical disk is characterized in that only the optical means for scattering light on the front side of the optical disk have at least one light passage region. Optionally provided on the back of the optical disk optical means for scattering light can be performed without light passage area.
Die Erfindung betrifft des Weiteren eine Heckleuchte mit einer vorab beschriebenen Optikscheibe. Die Heckleuchte ist vorzugsweise im Heckbereich eines Kraftfahrzeugs angebracht und kann ein Bremslicht und/oder ein Schlusslicht umfassen. The invention further relates to a taillight with an optical disc described above. The tail light is preferably mounted in the rear area of a motor vehicle and may include a brake light and / or a tail light.
Ein bevorzugtes Ausführungsbeispiel der Heckleuchte ist dadurch gekennzeichnet, dass ein der Lichtquelle zugeordneter Reflektor unterhalb und/oder oberhalb der Lichtquelle mit optischen Mitteln zum Streuen von Licht versehen ist. Die Begriffe unterhalb und oberhalb beziehen sich auf eine z-Richtung des Kraftfahrzeugs. Die z-Richtung ist senkrecht zu einer Ebene angeordnet, die von einer Fahrzeuglängsachse und einer Fahrzeugquerachse aufgespannt wird. Die Fahrzeuglängsachse wird auch als x-Richtung bezeichnet. Analog wird die Fahrzeugquerachse als y-Richtung bezeichnet. Die optischen Mittel zum Streuen von Licht sind vorzugsweise nur unterhalb der Lichtquelle an dem Reflektor vorgesehen. A preferred embodiment of the taillight is characterized in that a light source associated reflector below and / or above the light source is provided with optical means for diffusing light. The terms below and above refer to a z-direction of the motor vehicle. The z-direction is arranged perpendicular to a plane which is spanned by a vehicle longitudinal axis and a vehicle transverse axis. The vehicle longitudinal axis is also referred to as the x direction. Similarly, the vehicle transverse axis is referred to as y-direction. The optical means for diffusing light are preferably provided only below the light source on the reflector.
Ein weiteres bevorzugtes Ausführungsbeispiel der Heckleuchte ist dadurch gekennzeichnet, dass die Lichtquelle einen Lichtleiter umfasst. Der Lichtleiter ist, im Querschnitt betrachtet, innerhalb des Reflektors angeordnet. An einer Reflektoröffnung, die den Lichtaustritt ermöglicht, ist die Optikscheibe angeordnet. Another preferred embodiment of the taillight is characterized in that the light source comprises a light guide. The light guide is, viewed in cross section, disposed within the reflector. At a reflector opening, which allows the light exit, the optical disc is arranged.
Ein weiteres bevorzugtes Ausführungsbeispiel der Heckleuchte ist dadurch gekennzeichnet, dass die optischen Mittel zum Streuen von Licht eine Narbung, eine Mattierung, Optiklinien, eine Riffelung und/oder Rippen umfassen. Die optischen Mittel zum Streuen von Licht sind vorzugsweise als Narbung oder Mattierung mit einem Schlitz ausgeführt, der einen von der Narbung oder Mattierung nicht beeinflussten Lichtdurchtritt durch die Optikscheibe ermöglicht. Another preferred embodiment of the taillight is characterized in that the optical means for diffusing light comprise a grain, a matting, optical lines, a corrugation and / or ribs. The optical means for diffusing light are preferably in the form of graining or matting with a slit which allows light passage through the optical disk which is not influenced by graining or matting.
Ein weiteres bevorzugtes Ausführungsbeispiel der Heckleuchte ist dadurch gekennzeichnet, dass die Heckleuchte ein Bremslicht und/oder ein Schlusslicht mit einer vorab beschriebenen Optikscheibe umfasst. Die Optikscheibe ist vorzugsweise zwischen der Lichtquelle und einer Lichtscheibe angeordnet. Daher wird die Optikscheibe auch als Zwischenscheibe bezeichnet. A further preferred embodiment of the taillight is characterized in that the taillight comprises a brake light and / or a tail light with an optical disc described above. The optical disk is preferably arranged between the light source and a lens. Therefore, the optical disk is also referred to as a washer.
Die Erfindung betrifft des Weiteren ein Kraftfahrzeug mit einer vorab beschriebenen Heckleuchte. The invention further relates to a motor vehicle with a tail lamp described above.
