摘要： A multi-channel LED driving system includes a power adapter, a rectifying and filtering unit, a plurality of LED strings, and a plurality of linear regulators, a CC/CV controller, an optically coupled isolator and a PWM controller. The CC/CV controller detects the conducting currents flowing though the LED strings and DC voltage source outputting from the rectifying and filtering unit, and provides voltage compensation of the power adaptor. In addition, the linear regulators slightly modulate the current difference between the LED strings to achieve current-sharing control, thus stabilize the illuminating brightness generating by the LED.

摘要： A polarity-reversible dimming controller having function of switching light source has a power supply module and a dimming control module. The dimming control module receives an external PWM dimming signal to control a feedback signal of the power supply module so as to dim or power on/off an LED lamp. The dimming control module has an output current switching circuit, a switch control circuit and a dimming control circuit. The output current switching circuit performs a PWM control over a current outputted from the power supply module by using the external PWM dimming signal to maintain chromacity of the LED lamp as a constant. The switch control circuit turns off the PWM controller to enter a standby mode for saving power once the PWM dimming signal exceeds a threshold value. As a full-wave rectification is performed on the PWM dimming signal, the polarity match issue upon assembling can be disregarded.
