Abstract

LED-Lichtmodul umfassend wenigstens einen Strang (10) in Reihe geschalteter LEDs (18), Mittel zur Überwachung (26, 28, 30) des im Betrieb des Strangs durch den Strang fließenden Stroms und/oder der an dem Strang abfallenden Spannung, eine Stromversorgung der LEDs, Mittel zur Erfassung wenigstens eines weiteren Betriebsparameters der LEDs, die einen Sensor (24) zur Erfassung eines zu einem im Betrieb des Lichtmoduls abgegebenen Lichtstrom proportionalen Wertes und zur Ausgabe eines Signals auf Basis des Wertes umfassen, und eine Auswerteeinheit (16). Die Auswerteeinheit (16) steuert die Stromversorgung (10) der LEDs für einen dem LED-Strang zugeführten Strom in Abhängigkeit des Signals durch Pulsweitenmodulation und wird im Betrieb des Lichtmoduls ebenfalls über die Stromversorgung (20) der LEDs (18) mit Strom versorgt.
