Claim of US Patent No. 10,397,993

1. An LED module (1) comprising:voltage connections (12);
connections (2) for an LED series (3);
a circuit (4) which is configured and arranged to constitute:
a variable current at the volts, e connections (12) when a first supply voltage (5a) not equal to zero is applied to the voltage connections (12) of the LED module (1), the first supply voltage (5a) being dimensioned in such a manner that, in a case of a connection of an LED series (3), the latter is not conductive, wherein the variable current load effects a change in a power consumption of the LED module (1) according to a specified protocol, and
no load when a second supply voltage (5b) not equal to zero is applied to the voltage connections (12) of the LED module (1), at which, in the case of connection of the LED series (3), the latter is conductive and light is emitted, wherein the type of the load constituted by the circuit (4) is selected dependent upon the value of the first supply voltage and/or of a modulation of the first supply voltage,
wherein a voltage range of the first supply voltage (5a) is subdivided into a plurality of sub-ranges and wherein each sub-range corresponds to a different specified protocol
wherein, for each of the plurality of sub-ranges, the circuit (4) is configured to effect a change of the variable current load dependent on a value of the first supply voltage (5a) according to the specified protocol, of the sub-range,
wherein for each sub-range a different change of the power consumption of the LED module (1) is present.
