Abstract
The present invention provides a dimmable lighting apparatus, comprising a light emitting circuit and a driving circuit coupled with the light emitting circuit. The driving circuit comprises a rectifier module, a filtering module coupled between the light emitting circuit and the rectifier module, a constant current module coupled between the filtering module and the light emitting circuit, and a dimming module. In particular, the dimming module is configured to receive a driving signal supplied to the light emitting circuit from the constant current module, and feed the driving signal back to the constant current module to adjust an output power of the constant current module.
Claims14
