Abstract
A solid state lighting module is disclosed. In one example, the module comprises a light source and a resistor circuit, wherein an output resistance of the resistor circuit is for conveying to a connected driver information on a desired power to be applied to the solid state light source. A control interface is provided for receiving configuration information from an external configuration device and a control circuit configures the resistor circuit thereby to set the output resistance in response to received configuration information. This approach involves integrating the configuration function in the lighting module instead of in the driver. The output resistance can be determined by existing driver architectures without modification, while at the same time the ability of the user to tailor individual lighting modules to their needs is enabled.
