Abstract

The invention discloses a novel electronic ballast which comprises a control unit, a filter circuit, a rectification circuit, a protection circuit and an output stage circuit. The control unit is composed of a current sensor, a control circuit and a voltage sensor, the current sensor and the voltage sensor are used to detect the current and voltage of a load (R0) respectively, and the control circuit is used to receive signals of the voltage sensor and the current sensor and control operation of the ballast according to the received signals. According to the novel ballast, a light modulation function is realized, sweep frequency ignition can be used effectively eliminate resonant frequency drift caused by practical device parameter errors, the light modulation function can be used selectively according to practical conditions, resource configuration is more flexible, and the cost is reduced compared to the scheme in which an original electronic ballast needs to be changed to realize the function of light modulation.
