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 5):
The TRIAC dimmer detection circuit according to  claim 3 , wherein the control unit comprises a first control unit;\n the first control unit comprises a first delay circuit, a first logic module, a first counter and a second logic module; the first delay circuit delays the first processing signal; the first logic module receives the delayed first processing signal and the second processing signal, logically processes the delayed first processing signal and the second processing signal, and then outputs a first logic signal to a low-level valid zero clearing end of the first counter; a clock input end of the first counter is connected to an output end of the second logic module, and an output end of the first counter is connected to an input end of the second logic module; and the second logic module generates the dimmer detection signal according to the first processing signal, the dimmer detection signal is a leading-edge phase-cut TRIAC dimmer detection signal.
