Abstract (en)
A sensor (40) detects light intensity in a lighting device like LEDs (32). A device alters the current and/or voltage for the LEDs by relying on an output signal from the sensor, which also switches the LEDs off. The LEDs fit in a ring. A central support for the LEDs stretches along a ring axis. This support can also act as a heat sink (31). Independent claims are also included for the following: (a) An insert for a lantern with a cooling unit, sources of light and a sensor for light intensity; (b) and for a method for operating a lantern with a lighting device like LEDs.
Abstract (de)
Die Erfindung betrifft eine Laterne (10) mit mindestens einem elektrischen Leuchtmittel (32). Vorgesehen ist mindestes ein Sensor (40) zum Erfassen der Lichtstärke des Leuchtmittels. In Abhängigkeit vom Ausgangssignal des Sensors (40) werden Strom und/oder Spannung für das Leuchtmittel (32) geändert. Als Leuchtmittel sind insbesondere LEDs (32) vorgesehen. <IMAGE>
