Abstract
A light source module includes a light source and a light guiding pole. The light guiding pole is made of transparent material and has a light incident surface and at least one side surface connected to the light incident surface. The light source emits light rays, and faces the light incident surface. The light incident surface guides the light rays into the light guide pole, and the at least one side surface totally reflects the light rays. At least one slot is defined at the at least one side surface, and extends along a lengthwise direction of the light guiding pole. The at least one slot destroys the totally reflective path of a portion of the light rays arriving the at least one side surface, and thus the portion of the light rays emits from the at least one side surface.
Claims8
