摘要：NOVELTY - The unit has a silicon light modulator fixed with an input end of an AC power source. The silicon light modulator is fixed with an output end of a rectification filter circuit. A signal output end of the rectifying filtering circuit is connected with a stabilizing circuit. The stabilizing circuit is provided with a control signal input end that is fixed with a control circuit. A constant-current circuit is fixed with an LED driving power adjustable unit. The rectifying filtering circuit is provided with a rectification circuit and a filter circuit. USE - LED constant power source unit. ADVANTAGE - The unit realizes LED flexible linear dimming effect. DETAILED DESCRIPTION - The rectifying circuit is a bridge rectifier circuit. DESCRIPTION OF DRAWING(S) - The drawing shows a circuit block diagram of an LED constant power source unit.
