1. A constant current driver comprising an apparatus for controlling the constant current driver, the apparatus being configured to measure an output voltage of the constant current driver applied to a luminaire module, to determine whether the measured output voltage exceeds an operating range of a current control mode of the constant current driver, and to reduce the output current of the constant current driver if the measured output voltage exceeds the operating range,
wherein the apparatus is configured to reduce the output current to the same value as consumed by the luminaire module if the measured output voltage exceeds the operating range, and
wherein the apparatus is configured to control the constant current driver to generate a pulsed output current, wherein a maximum value of the pulsed output current is equal to or larger than the operating range of the current control mode, and to determine a presence of a non-matching luminaire module if the output voltage of the constant current driver comprises a pulsed component.
