Description

English projection system

Technical Field

The invention relates to a projection system, in particular to an English projection system.

Background

The invention provides a projection system and a driving method of the projection system, and discloses the projection system with the application number of CN201910149348. X. The projection system comprises a fluorescent wheel, a motor, a light source module, a processing control module and a power supply module. The motor is used for rotating the fluorescent wheel. The light source module is used for providing an excitation light beam. The power module is used for providing motor current and driving current for the light source module. When the projection system is started, the power module provides a driving current with a first current value, and provides a motor current and gradually increases the current value of the motor current, so that the motor rotates the fluorescent wheel and gradually increases the rotation speed of the motor. The processing control module receives a rotating speed signal of the motor, and when the rotating speed of the motor reaches a preset rotating speed, the processing control module controls the power supply module to increase the current value of the driving current from a first current value to a second current value. The starting time of the projection system is effectively shortened under the condition that the fluorescent wheel can be prevented from being burnt or aged by the excitation light beam provided by the light source. But this patent does not facilitate english projection.
