Title:
INTELLIGENT LAMP CONTROL SYSTEM AND FLICKER CONTROL CIRCUIT THEREOF
Document Type and Number:
WIPO Patent Application WO/2020/211113
Kind Code:
A1
Abstract:
Disclosed are a flicker control circuit and an intelligent lamp control system. The flicker control circuit comprises a rectification circuit, a flicker detection circuit, a DC-DC conversion circuit and a control circuit, wherein an input end of the rectification circuit serves as an input end of the flicker control circuit, and the rectification circuit is used for rectifying an input alternating current; an input end of the flicker detection circuit is connected to the input end of the rectification circuit, an output end of the flicker detection circuit is connected to a first input end of the control circuit, and the flicker detection circuit is used for detecting a flicker phenomenon of an alternating current and outputting a generated flicker detection signal to the control circuit; an input end of the DC-DC conversion circuit is connected to an output end of the rectification circuit, and the DC-DC conversion circuit is used for supplying power to the control circuit; and the control circuit is used for adjusting a working state of a controlled device according to the flicker detection signal. In the present application, a flicker detection circuit is provided at an input end of a rectification circuit, such that the sensitivity and accuracy of a detection result can be effectively improved.
