The light guide plate is made of optical-grade acrylic/PC sheet, and then uses high-tech materials with extremely high refractive index and no light absorption, and uses laser engraving, V-shaped cross grid engraving, and UV screen printing technology on the bottom surface of the optical-grade acrylic sheet. Print light guide points. The optical-grade acrylic sheet is used to absorb the light emitted from the lamp and stay on the surface of the optical-grade acrylic sheet. When the light hits each light guide point, the reflected light will spread to all angles, and then destroy the reflection conditions and be emitted from the front of the light guide plate. Through various light guide points of different density and size, the light guide plate can be made to emit light evenly.
