Abstract

The utility model relates to a projection lamp control circuit, which relates to the technical field of projection lamps and comprises a power supply device, an adjusting device and a projection device. The power supply device is connected with the adjusting device, the projection device is connected with the adjusting device, the power supply device outputs a voltage signal, the adjusting device receives the voltage signal and outputs a stable voltage signal, and the projection device receives and responds to the stable voltage signal to emit light for projection; when the voltage value of the voltage signal is not equal to the voltage value of the stable voltage signal, the adjusting device outputs the stable voltage signal, and when the voltage value of the voltage signal is equal to the voltage value of the stable voltage signal, the adjusting device is not triggered. The projection lamp control method and the projection lamp control device have the effect of improving projection lamp control convenience.
