Abstract:
1. A light guide plate adapted for distributing light from a light source, the light guide plate comprising: a light scattering surface; a light output surface opposite to the light scattering surface; and a plurality of side surfaces surrounding the light scattering surface and the light output surface, wherein the light scattering surface comprises a mounting portion adjacent to a side surface of the light guide plate and a light scattering portion beside the mounting portion, a plurality of light scattering dots are formed on the light scattering portion of the light scattering surface; at least two receiving recesses are defined at the mounting portion adjacent to first side of the light scattering, surface, a mounting hole is defined approximately in a middle portion of the light scattering surface, the at least two receiving recesses are obliquely oriented to the mounting hole and are adapted for receiving at least two light sources therein; and the light scattering dots surround the mounting hole and are arranged in a plurality of rows from the first side of the light scattering surface to an opposite second side of the light scattering surface, and a distance between every two adjacent rows of the light scattering dots gradually decreases from the first side to the second side of the light scattering surface, such that the light scattering dots at the second side of the light scattering surface have a greater density than the light scattering dots at the first side of the light scattering surface.
