At both ends of the pipe 1, there are provided ring-shaped hooks 2 and 2 which can be fitted to tips of triangular pyramid-shaped poles (pylons) often used on road surfaces. As a preferred embodiment, the outer diameter of the pipe 1 is 34 mm, the length of the light transmitting portion 3 is 250 mm, and the length of the light non-transmitting portion 4 is 125 m.
m, the length of the light-emitting bar frame connecting the centers of the left and right hooks 2 and 2 was 2000 mm.

In the pipe 1, two light emitting diodes LED1 to LED8 are arranged in each of the light transmitting portions 3. Further, an input connector 5 for receiving a 100V power supply is provided at one end of the pipe 1. From the input connector 5, an AC / DC converter 6 and a switching circuit 7 are connected to the light emitting diodes of the adjacent light transmitting portions 3. An electric circuit 10 for alternately supplying a voltage is provided. Thereby, the adjacent light emitting diodes are alternately turned on and off.

An electric circuit 10 including the AC / DC converter 6 and the switching circuit 7 is formed on a substrate 11 shown in FIG. 3, and the substrate 11 and the light-emitting diodes LED1 to LED8 are arranged in a pipe 1 It is held on a plate 12. The reflecting plate 12 is mounted in the pipe 1 by the following means. That is, a pair of left and right insertion grooves 13, 13 are provided along the axial direction at opposing locations on the inner surface of the pipe 1.
It is attached by inserting the reflection plate 12 from the opening at one end of the pipe. Also, the cap 2a integrated with the hook 2 is firmly fitted into the opening at both ends of the pipe 1 to close the opening at both ends of the pipe, and at the same time, the hook 2 and the pipe 1 are firmly connected. . With such a structure, the light emitting bar frame can be easily assembled.
