Abstract

This utility model discloses a novel, sealed, dustproof, and waterproof light source, relating to the field of visual recognition technology. It includes: an inner cavity with an interface for mounting a telecentric lens; a light source plate mounted within the inner cavity; a transparent light guide plate mounted within the inner cavity and covering the light source plate; an outer shell mounted outside the inner cavity; an air-passing and wire-passing block mounted within the inner cavity, comprising a first air pipe connector, a second air pipe connector, and a channel for passing wires; and an air-blowing pipe connected to the bottom of the air-passing and wire-passing block. This utility model prevents water mist from adhering to the surface of the telecentric lens and the light source plate, prevents external water mist from entering the light source area, ensures light source brightness and image clarity, eliminates misidentification caused by cutting residue, achieves miniaturization, and simplifies the layout of external pipelines.
