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 8):
The TRIAC dimmer detection circuit according to  claim 5 , wherein the first logic module comprises a first D flip-flop, and the second logic module comprises a first OR gate and a NOT gate;\n a trigger end C of the first D flip-flop is connected to an output end of the first delay circuit, an input end D is connected to an output end of the second comparator, and an output end Q is connected to a low-level valid zero clearing end of the first counter; an output end of the first counter is connected to a first input end of the first OR gate; an input end of the NOT gate is connected to an output end of the first comparator, and an output end is connected to a second input end of the first OR gate; and an output end of the first OR gate outputs a leading-edge phase-cut TRIAC dimmer detection signal.
