Modular light guide plate
The present invention relates to a modular light guide plate comprising a light guide plate including a side wall used for entering the light to couple the light emitted by the LED into the interior of the light guide plate, an upper surface and a lower surface, and a reflective sheet arranged below the lower surface of the light guide plate and having a high reflectivity to the light emitted by the LED, wherein the lower surface of the light guide plate is provided with a raised dot, which is bonded to the lower surface of the light guide plate at the upper end thereof and to the upper surface of the reflective sheet at the lower end thereof, and the material of the dot body is a transparent optical material, and optical particles are uniformly dispersed in the dot, thereby having the advantages of high light extraction efficiency.
