A lateral planar light emitting module has a rectangular base plate and a plurality of light emitting diodes, and the light emitting diodes are designed with an array arrangement and installed on both opposite sides of the rectangular base plate respectively, so that a light exit surface opposite to a light projection area with a different intensity produced by the same light emitting diode has an optical path with a different distance after a light source emitted from the light emitting diodes is projected directly or reflected from a reflective micro-structure of the rectangular base plate, and a light emitting effect with a uniform light intensity distribution is achieved on the light exit surface to lower the manufacturing cost and improve the light emitting efficiency effectively. |
