Abstract
A light source module comprises a plurality of laser light sources, a lens module, a plurality of optical components, and a light guiding plate. The lens module includes a first lens having a rear arced plane and a plurality of second lenses each having a front arced plane, and the second lenses are positioned on the first lens and protruded forwardly from the first lens toward the optical components. The optical components are positioned on light path of light emitted from the laser light sources in sequence and each correspond to one second lens, and the optical components are, except the farthest one from the laser light sources, beamsplitters, respectively and used for reflecting a part of the light emitted from the laser light sources to the second lenses and permitting another part of the light to penetrate therethrough to a next optical component.
