摘要
The invention discloses a circuit of dimming and toning based on a driver on board module, relates to LED driving circuit technology field, which includes a silicon controlled dimming circuit module, a rectifier module, an AC constant current power supply module, a plurality of balanced architecture LED modules, and a color feedback comparison module. The AC constant current power supply module includes a plurality of AC constant current power supply sub units supplying power for the balanced architecture LED modules correspondingly. The color feedback comparison module is located between two balanced architecture LED modules to compare voltages generated thereby and no power contrast feedback between two balanced architecture LED modules is generated when the silicon controlled dimming circuit module adjusts current, so that the color feedback comparison module makes an LED bead thereof to choose road between the balanced architecture LED modules to realize color temperature adjusting.
