    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.
