A light source module utilized in a photoelectric scanning device for offering a light source to scan an article comprises a light emitting diode, a light guiding rod and several light reflection structures. The light reflection structure has a reflector with a specific width and depth, positioned in opposite to the light output side of the light guiding rod, further with a distance to the light emitting diode to produce a specific light intensity, in order to compensate the light aberration of the lens module.
