Abstract:
The invention provides a current modulating circuit, for example for use in a driving circuit for driving a lighting load such as an LED arrangement. A current modulating element is provided in series with the lighting load, and modulates the current based on a data input signal. A feedback system controls the current modulating element, and it has a first feedback control path which uses a voltage across the current modulating element, and a second feedback control path which uses the data input signal. The voltage feedback is used to maintain the overall current equal to the current output from a driver. The difference in current is taken up by a capacitor at the output of the driver.

Claim (Index 1):
A current modulator circuit for modulating a drive current through a lighting load, comprising:\n a current modulating element for modulating the light output of the lighting load based on a data input signal, wherein the current modulating element is adapted to be connected in series with the lighting load; and a feedback system for controlling the current modulating element thereby to implement modulation of the current through the lighting load, wherein the feedback system comprises: a first feedback control path having as input a voltage across the current modulating element, wherein the first feedback control path comprises a comparator arrangement for comparing a measured voltage across the current modulating element with a reference voltage and a low-pass filter between an output of the comparator arrangement and a control input of the current modulating element; and a second feedback control path having as input the data input signal.
