Patent number: 10492272Abstract: 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.Type: GrantFiled: March 20, 2018Date of Patent: November 26, 2019Assignee: XIAMEN ECO LIGHTING CO. LTD.Inventors: Wenchang Huang, Hemu Ye, Wei Liu, Zongjin Liu, Jie Zhang, Xiaobo Chen
