Abstract:
A LED sensing light driving circuit includes a rectifying filter circuit, a buck power-supplying circuit, a constant current driving circuit, a sensing signal generating circuit, and a hysteresis comparator circuit. The rectifying filter circuit has a DC output terminal supplies power to the sensing signal generating circuit and the hysteresis comparator circuit via the buck power-supplying circuit. The sensing signal generating circuit reduces a voltage at a first input terminal of the hysteresis comparator circuit in response to increase or decrease of surrounding luminance.

Claim (Index 19):
An LED sensing light driving circuit, comprising:\n a rectifying filter circuit; a sensing signal generating circuit; a buck power-supplying circuit; a constant current driving circuit; and a hysteresis comparator circuit; wherein the rectifying filter circuit is configured to supply power to the sensing signal generating circuit and the hysteresis comparator circuit via the buck power-supplying circuit; wherein the sensing signal generating circuit is configured to reduce an input voltage of the hysteresis comparator circuit in response to an increase or a decrease of surrounding luminance; wherein the hysteresis comparator circuit is configured to reverse its output voltage when a voltage level of the input voltage exceeds a first threshold voltage of the hysteresis comparator circuit or falls below a second threshold voltage of the hysteresis comparator circuit; wherein values of the first threshold voltage and the second threshold voltage are different; and wherein the output voltage of the hysteresis comparator circuit is used for controlling a pulse-width modulation (PWM) input signal of the constant current driving circuit.
