Laser light guide plate: The light guide plate is made of optical grade acrylic PMMA, MS sheet, and laser engraved on the bottom 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 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 uniformly.
