Abstract
A linear light source device is provided having a main body that includes at least a light-guided bar and a light source assembly. The light-guided bar is a polygonal column with one striped surface forming, a reflective plane. The plane the opposite to reflective plane is a light-exiting plane having a convex profile, with the remaining planes being reflective planes. At least one of the ends of the polygonal column is an incident plane for a light beam to enter. The light beam is uniformly transmitted through the convex-shaped light-exiting plane.
