Adaptive control apparatus and method for a solid state lighting system |
摘要 |
The present invention provides a method and apparatus for adaptive control of a solid-state lighting system consisting of one or more groups of one or more light-emitting elements The invention comprises a voltage control device to provide each group with an independently controllable voltage A feedback system to detect and generate a signal representative of drive currents through the one or more groups A computing device then adaptively evaluates, based on the signal, a required voltage that achieves a desired respective drive current in each of the one or more groups.
