Abstract:
Provided are a TRIAC dimmer detection circuit, chip and method, and an LED driving chip and system. A bus voltage reflecting signal is received, and a TRIAC dimmer detection signal is generated according to the bus voltage reflecting signal, a first reference voltage and a second reference voltage, the dimmer detection signal being used to detect whether a dimmer exists and to determine the type of the dimmer. The TRIAC dimmer detection circuit, chip and method, and the LED driving chip and system consistent with the present invention can detect whether a TRIAC dimmer is contained in an LED illuminating system, so as to determine a working state of a bleeder, thereby reducing the power consumption of the entire LED illuminating system and improving the efficiency thereof.

Claim (Index 19):
An LED driving system, comprising:\n a rectification unit, configured to rectify an input alternating current and then output it to an LED load; an energy storage unit, connected to an input end and an output end of the LED load; an LED driving circuit, configured to provide current for the LED load; a TRIAC dimmer detection circuit according to  claim 1 , configured to generate a TRIAC dimmer detection signal according to a signal representing the bus voltage; and a bleeder, configured to make a turn-on or turn-off response according to the dimmer detection signal, wherein when a current of the LED driving circuit is smaller than a minimum current for maintaining an on state of a TRIAC dimmer, the bleeder adjusts a working mode thereof according to the dimmer detection signal, and provides an extra current to maintain the on state of the TRIAC dimmer.
