Abstract
The present technology is generally related to Triac dimmer compatible driving circuits and methods thereof. The present technology also provides an electronic transformer that is integrated in the Traic dimmer compatible driving circuit. In one embodiment, the electronic transformer detects the conduction angles of an output AC voltage from the Triac dimmer and converts said output AC voltage into a PWM DC voltage having a duty cycle regulated by said conduction angles. Said PWM DC voltage is then applied to a WLED driver for driving a WLED.
