<P>PROBLEM TO BE SOLVED: To provide a spontaneous light emission road sign substrate capable of changing a direction of a light emission diode when the light emission diode is mounted on the substrate. <P>SOLUTION: In the spontaneous light emission road sign substrate 1, at least one of two insertion holes 2 wherein lead wires 31 of the light emission diode 3 are fixedly inserted is made as a slot 22 to enable the leads 31 of the light emission diode 3 to freely slide in the slot 22, and when the light emission diode 3 can only fixed to the optimum position, the direction of the light emission diode 3 can be changed without using any special other member. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
