Abstract:
The present invention relates to a lighting system for analyzing pellet and a foreign matter sorting apparatus comprising same. The lighting system for analyzing pellet comprises: a casing (100) which has an inner space and a through-hole (110) formed in the upper surface, and in which objects to be sorted (P), including a plurality of pellets, move across the inner upper portion and the inner lower portion; an upper lighting assembly (200) which includes a plurality of first light sources (210) each irradiating first illumination light, and a first light source holder (220) which fixes the first light sources (210) so that a row direction light source array, in which some of the first light sources (210) are arranged in the lengthwise direction of a virtual curved surface, is arranged in parallel along the arc direction of the virtual curved surface, wherein the virtual curved surface, of which the arc direction is the vertical direction, is convex toward the objects to be sorted (P), and the upper lighting assembly (200) is arranged on the inner upper portion of the casing 100 and irradiates the first illumination light toward the upper and side portions of the objects to be sorted (P); and a lower lighting assembly (300) comprising a plurality of second light sources (310) each irradiating second illumination light, and a second light source holder (320) which fixes the plurality of second light sources (310), wherein the lower lighting assembly (300) is arranged on the inner lower portion of the casing (100) and irradiates the second illumination light toward the lower and side portions of the objects to be sorted (P).
