Patent number: 11991797Abstract: A LED power supply with bi-level dimming receives an input voltage to supply power to an LED lamp, and adjusts the brightness of the LED lamp according to whether an external detection switch is triggered to be turned on. The LED power supply includes a conversion circuit, a switch, and an oscillation circuit. The conversion circuit converts the input voltage into an output voltage, and provides the output voltage to supply power to the LED lamp so as to control the LED lamp to provide a first brightness. The oscillation circuit provides a dimming signal with a fixed frequency and a duty cycle to the switch when the external detection switch is turned on so as to turn on and turn off the switch. The switch correspondingly adjusts the output voltage according to the dimming signal to control the LED lamp to provide a second brightness.Type: GrantFiled: January 17, 2023Date of Patent: May 21, 2024Assignee: DELTA ELECTRONICS, INC.Inventors: Ching-Ho Chou, Yung-Chuan Lu
