Abstract
The utility model provides a ballast circuit for a solar direct-current electrodeless lamp, and the ballast circuit consists of a boost voltage-stabilizing circuit, a rectification filter circuit, a drive control circuit, an integrated-chip working-power circuit, a lamp service-life abnormality protection circuit, and a power output circuit. An external solar storage battery power supply passes through the boost voltage-stabilizing circuit, and then is converted into a direct-current power supply by the rectification filter circuit. The direct current directly passes through drive control circuit, the lamp service-life abnormality protection circuit, and the power output circuit, thereby achieving the work for the electrodeless lamp. The abnormality protection circuit acquires a voltage output signal from the power output circuit. After processing, the signal is transmitted to a drive control circuit. The drive control circuit controls the power output circuit according to the voltage signal outputted by the lamp service-life abnormality protection circuit. The integrated-chip working-power circuit supplies stable working power to an IC of the drive control circuit, thereby guaranteeing the stable operation of the ballast of the solar direct-current electrodeless lamp.
