[0002] A light guide plate is an optical material, usually made of high-transmittance plastic (such as acrylic, polycarbonate, etc.). The main function of a light guide plate is to convert a line light source or a point light source into a surface light source, thereby achieving a uniform lighting effect. It is widely used in many fields, such as liquid crystal display (LCD) backlights, LED lamps, advertising light boxes, etc., and can provide a soft and comfortable lighting effect by utilizing its ability to evenly diffuse the light source over the entire area, while also achieving energy-saving and compact design requirements. In addition, light guide plates can also be used in solar photovoltaic panels, car taillights, medical equipment, and many other occasions to give full play to their excellent optical properties.

The light guide plate is easily deformed during the cleaning process, affecting the subsequent use effect. In addition, if the cleaning process is not stable enough, scratches may appear on the surface of the light guide plate, seriously reducing the product quality. Utility Model Content
