<P>PROBLEM TO BE SOLVED: To provide a fluorescent rod system capable of obtaining sufficient brightness as compared with a conventional fluorescent lamp, in a cylindrical light-emitting body in which light-emitting diodes with less power consumption than the fluorescent lamp are used, light of a less number of light-emitting diodes is made incident from an end part, and a side face light emission is realized. <P>SOLUTION: The fluorescent rod system includes: a cylindrical light guide body 0101; light-emitting diodes 0102 making light incident on the cylindrical light guide body from an end part of the cylindrical light guide body; at least one strip-shaped light-reflecting layer 0103 arranged along a length direction of the cylindrical light guide body; and at least one or more rows of a semicylindrical-shaped lens layers 0104 along the length direction of the cylindrical light guide body. <P>COPYRIGHT: (C)2012,JPO&INPIT |
