| Zusammenfassung: | The utility model discloses a bulb control circuit and an electronic device. The bulb control circuit comprises a switch branch, a rectification branch, a voltage reduction branch and a power control branch. The switch branch circuit is connected with an input power supply and the rectification branch circuit, the rectification branch circuit is connected with the voltage reduction branch circuit and the power control branch circuit, the voltage reduction branch circuit is connected with the power control branch circuit, and the power control branch circuit is respectively connected with the switch branch circuit and the bulb. The switch branch circuit is used for establishing connection between the input power supply and the bulb or establishing connection between the input power supply and the rectification branch circuit. The rectification branch is used for rectifying an input power supply and outputting a first power supply to the voltage reduction branch. The voltage reduction branch is used for reducin |
