Abstract
A linear illuminant system includes a light emerging device composed of a light transmission cylinder and light source coupled to one or both longitudinal ends of the light emerging device, in such a manner that light entered from the light source is emitted from the longitudinal side surface of the light emerging device. At least one strip-shaped reflecting layer is formed by printing along the length of the side surface of the light transmission cylinder. In manufacturing a linear illuminant system, the reflecting layer is formed on the side surface of extruded light transmission cylinder by printing in line with the extrusion molding process of the light transmission cylinder.
