[0003] The lens is the key component of the imaging and projection of the projector. It is a precision equipment and has certain requirements for the operating environment temperature, moderation, and cleanliness, especially dust. Dust will seriously reduce the display brightness of the projector and affect the use of internal glass components. life

[0004] When the traditional projector is placed for a long time, a large amount of dust will adhere to the surface of the lens, and the staff needs to clean the dust in time. Once the cleaning is not timely, the dust will wear the surface of the lens and affect the effect of watching movies.
