Abstract

The invention relates to an LED module (1), comprising: connections (2) for an LED series (3); a circuit (4), which is designed to constitute a load, preferably an active-power load, when a first supply voltage (5a) not equal to zero is applied to the LED module (1), which active-power load is dimensioned in such a way that, when an LED series (3) is connected, said LED series is not conductive, and which is designed to constitute no load when a second supply voltage (5b) not equal to zero is applied to the LED module (1), for which second supply voltage, when an LED series (3) is connected, said LED series is conductive and light is emitted, wherein the type of load change is selected in dependence on the value of the first supply voltage and/or a modulation of the first supply voltage.
