Abstract:
1. A light source module, comprising: a plurality of light emitting diodes; a base comprising a side face, wherein the plurality of light emitting diodes are mounted at the side face; and a light guide plate comprising at least three side faces, one of which is opposite to the plurality of light emitting diodes and defines a light input surface, and the others of which define light output surfaces; wherein the light input surface has at least one recess defined thereat thereby defining a plurality of light incident surfaces respectively corresponding to the light output surfaces, and the light emitting diodes face the light incident surfaces, respectively, such that a majority of light beams from each light emitting diode are capable of substantially perpendicularly propagating into the corresponding light incident surface and exiting from a corresponding one of the light output surfaces.
