Abstract
The present invention relates to a light stick for scanners which mainly includes a strip-shaped plate, wherein the broadside thereof protrudes outwards in an arched shape, and wherein a protruding strip is extended along the outer broadside of the arched strip-shaped plate and is semicircular in section, and wherein a protruding and rectangular rear seat is disposed at the other side of the strip-shaped plate and situated opposite to the protruding strip. And this rear seat has an arched surface at the center thereof and corresponds to the arc of the strip-shaped plate. Moreover, two light sources are disposed near two ends of the rear seat of the light stick respectively, and the light stick will not only achieve a broader scanning range with the least light sources due to the light refraction, light condensing and diffusion, but also the energy can be saved.
