Abstract: The present invention relates to a light outputting apparatus, which includes at least one light source, a light guiding apparatus and a platform. The light source is used for providing light beams. The light guiding apparatus has at least one input end and an output end. The input end corresponds to the light source, and includes a plurality of optical fibers. The optical fibers of the input end extend to the output end, and are distributed uniformly at the output end. The light beams from the output end illuminate a module to be tested on the platform. Whereby, the entire uniformity of the output light of the output end is enhanced.
