Abstract:
1. A linear light source device comprising: a light source assembly comprising a positioning plane, a reflective surface, a mounting plane, and a light-emitting diode mounted in the reflective surface; and a light-guide bar comprising a polygonal column, a light-exiting plane, a reflective plane, and a plurality of reflective layers and further comprising at least a tail end of said light-guide bar being an incident plane for light to enter, wherein the reflective plane comprises surface stripes and is positioned opposite the light-exiting plane, and the reflective layers have a reflecting function so that the light transmitting into the incident plane and through the polygonal column and reflected off of the reflective plane and layers is transmitted out of the light-exiting plane; and a light-reflective sheath covering a portion of the reflective layers and the reflective plane.
