Abstract
A luminaire driver apparatus for use with one or more light emitting diodes or other light sources, comprises voltage control circuitry configured to regulate a supply voltage to one or more light emitting diodes or other light sources; driving circuitry configured to provide a drive current to the one or more light emitting diodes or other light sources, the drive current being dependent on the supply voltage, wherein the driving circuitry is configured to modulate the drive current based on a modulated drive signal such that the one or more light emitting diodes or other light sources produces an optical signal, wherein at least one of the driving circuitry and control circuitry are operable to adapt to a plurality of different types of light emitting diode or other light source. Thereby providing a universal driver function.
