Publication number: 20230083055Abstract: A driving circuit for driving a light source and a projection device are provided. The driving circuit includes a power converter, a detection circuit, and a control circuit. The power converter provides a driving power to the light source. The detection circuit provides a feedback signal according to a current value of the light source. The control circuit receives an operation command and the feedback signal. The control circuit determines whether the driving circuit enters a light-load state according to at least one of the operation command and the feedback signal. When the driving circuit is determined to enter the light-load state, the control circuit controls the power converter to decrease a current value of the driving power and controls the power converter to increase a switching frequency of the driving power. The driving circuit and the projection device may prevent the light source from flickering under the light-load state.Type: ApplicationFiled: September 14, 2022Publication date: March 16, 2023Applicant: Coretronic CorporationInventors: Chia-Wen Hsu, Chen-Wang Chen, Tung-Min Lee
