Abstract

A pulse frequency modulation (PFM) based LED illuminator includes a plurality of light sources 210, 220, 230 of at least two colours. The light sources are coupled to a power circuit which includes a power supply 100, a driver 510 for driving the light sources to emit light, and a controller 500. The controller has a variable address for identifying the illuminator and responds to an input signal addressed to the controller. The controller is used for generating PFM signals which correspond to individual colours of the plurality of light sources. A plurality of such illuminators may be used in a light network having a central controller operating on the DMX standard.
