Abstract

The invention provides projection equipment and a control method thereof. The equipment comprises a projection control system, a system power supply for providing power for the projection control system, a light source driving power supply and a power supply control unit. The power supply control unit is in communication connection with the projection control system for interaction. The power supply control unit is electrically connected with the system power supply and the light source driving power supply to carry out control. Accordingly, functions are integrated, the hardware structure is simplified, hardware cost is lowered, engineering design is easy, whole systemic reliability is greatly improved, terminal and external wire connecting is lowered, occupied space is lowered, EMI is lowered, and a system is stable.

Description

technical field [0001] The present invention relates to the field of projection technology, in particular to a projection device and a control method thereof. Background technique [0002] The existing projection equipment power supply system mainly includes AC / DC power supply, light source drive power supply, and projection control system power supply. In the traditional architecture, two microcontrollers are needed for power control and light source drive; the purpose of power control is to make The projection system meets the requirements of environmental protection and energy saving, and reduces the power consumption of the projection system to the minimum; the purpose of light source drive power control is to make the output of the light source follow the demand of the screen, change the output energy of the light source, and optimize the projection screen. Traditionally, micro The controller communicates with the main system for control. [0003] Therefore, the proble...
