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.

Figure imgaf001
LED light module comprising at least one string (10) of serially connected LEDs (18), means for monitoring (26, 28, 30) the current flowing through the string during operation of the string, and / or the voltage dropping across the string, a power supply the LEDs, means for detecting at least one further operating parameter of the LEDs, which comprise a sensor (24) for detecting a value proportional to a luminous flux emitted during operation of the light module and outputting a signal based on the value, and an evaluation unit (16). The evaluation unit (16) controls the power supply (10) of the LEDs for a current supplied to the LED string as a function of the signal by pulse width modulation and is powered during operation of the light module also via the power supply (20) of the LEDs (18) with power.
