Design of Sustainable Power Supply Control Circuit for Projector Cooling Fan
Projector is widely used in teaching and other places,its correct shutdown method is remote shutdown,and in fact,there is often an incorrect shutdown situation such as direct power off,which will result in the projector bulb heat can not be smoothly distributed,and seriously affects the service life of the projector.Based on this situa-tion,a sustainable power supply control circuit for the projector cooling fan is designed.The power supply detection circuit,lamp temperature detection circuit,lithium battery and sustainable power supply control circuit are added to the power supply circuit of the projector,and the working principle of the circuit is analyzed.Through analysis,it is proved that the control circuit is suitable for all kinds of projector power supply circuit,which can ensure the smooth heat dissipation of the lamp in different states,improve the service life of the lamp,and it has very broad application prospect.
