Abstract
Eine LED-Vorrichtung (1) mit veränderlichem Abstrahlwinkel weist mehrere LEDs (2) auf, die nebeneinander auf oder in einen elastischen Träger (3) montiert sind. Ferner weist die LED-Vorrichtung (1) eine Einrichtung (4) zur gezielten Verformung des elastischen Trägers (3) auf. Die LEDs (2), der elastische Träger (3) und die Einrichtung (4) zur gezielten Verformung des elastischen Trägers (3) sind derart gestaltet und angeordnet, daß durch die gezielte Verformung des elastischen Trägers (3) mittels der hierzu vorgesehenen Einrichtung (4) die Veränderung des Abstrahlwinkels der LED-Vorrichtung (1) hervorgerufen wird. A variable angle LED device (1) has a plurality of LEDs (2) mounted side by side on or in an elastic support (3). Furthermore, the LED device (1) has a device (4) for the targeted deformation of the elastic support (3). The LEDs (2), the elastic support (3) and the device (4) for the targeted deformation of the elastic support (3) are designed and arranged such that by the targeted deformation of the elastic support (3) by means provided for this purpose ( 4) the change of the radiation angle of the LED device (1) is caused.
