摘要 |
A compact light source module includes a compact light source and a collimator that includes a parabolic first reflective surface to reduce a radiation angle at which a light beam radiates from the compact light source, so as to emit the light beam through a side aperture and a plane second reflective surface which is located under the first reflective surface and comprises an incident portion through which the light beam radiates from the compact light source. The compact light source is located in the vicinity of a focal point of the first reflective surface.
