Abstract:
A linear light source device comprising:a light source assembly comprising a non-closed mounting plane, at least a reflective end plane; at least a positioning plane, and at least a light-emitting diode (LED) mounted on the reflective end plane; and a light-guided bar including a polygonal column, at least a light-exiting plane, a reflective plane, and a plurality of reflective layers and further including at least a tail end plane of said light-guided bar being an incident plane for light beam to enter, wherein at least two planes in opposite locations of said light-guided bar being the reflective plane with surface stripes and a corresponding light-exiting plane, and the other planes being reflective layers with reflecting function so that the light beam transmitting into the incident plane and through the transmission of the polygonal main body as well as the multiple reflection of the reflective planes can transmit out of the light-exiting plane with relatively uniform light beam.
