PROBLEM TO BE SOLVED: To provide a road-shoulder lighting apparatus that is particularly effective in the snow drifting.SOLUTION: An LED driven by using electric power generated by a solar panel 12 as a power source is built in toward the vertical direction, and a lighting box 7 having a mounting bracket to post-fitting it to an existing strut 3 for installing fletchings is provided. Furthermore, the solar panel 12 and a storage battery for accumulating electric power generated by the solar panel 12, and a night/day detection sensor and a climate change detection sensor for detecting various weather conditions, are built therein. Also, a control circuit for controlling the LED by the signal from the night/day detection sensor and the climate change detection sensor is also built therein. Furthermore, a control box 10 with a mounting bracket 10a to post-fit it to the strut 3 for mounting the fletchings 2 is provided. The lighting box 7 and the control box 10 are separately installed to the strut 3 in a post-fit system, and used. |
