This utility model discloses a strobe bar light and a visual inspection system. The strobe bar light includes a housing and optical components. The housing has a mounting cavity. The optical components include a light bar, a focusing rod, and a diffuser plate, which are sequentially installed in the mounting cavity along the width direction of the housing. Multiple heat sinks protrude from one side of the outer wall of the housing, extending along the length direction of the housing and spaced apart along the width direction. The housing also has a cooling channel located on the side of the light bar away from the diffuser plate and extending through the housing along its length. The integrated installation of the optical components, heat sinks, and cooling channel within the housing results in a thin and light-emitting strobe bar light with bright and uniform light output, high heat dissipation efficiency, and stable operation.
