Latest Patents

Xiaohua Sun's latest patents include a dimming mode detection circuit, a dimming mode detection method, a non-dimming mode detection circuit, and an LED lighting system. The dimming mode detection circuit is designed to receive an alternating current input voltage and generate a bus voltage to drive an LED load. It features a leading edge detection circuit that generates a leading edge detection signal by detecting the leading edge of a voltage representative of the bus voltage in one sine half-wave cycle. This helps determine whether the LED lighting system operates in a leading edge dimming mode. Additionally, a trailing edge detection circuit generates a trailing edge detection signal based on the time length of an interval from a first value of the voltage in a previous sine half-wave cycle to a second value in the next sine half-wave cycle, allowing for the determination of whether the system operates in a trailing edge dimming mode.
