POST EQUIPPED WITH REFLECTING BODY AND LIGHT-REFLECTING BODY

摘要

PROBLEM TO BE SOLVED: To provide a post equipped with a reflecting body using a reflecting plate in which prismatic irregularities are formed on the rear face, which has a totally circumferential reflecting body always retaining a sufficient reflecting quantity of light in the wide change of incident angles and a minute observation angle and has excellent optical characteristics and further, can reduce the cost. SOLUTION: The base fixing part 4 of a totally circumferential light- reflecting face 3 is covered with a regular polygon of twenty-four angular shape near to a little smaller diameter circle than the circular line of a supporting column body 2. Four bases 7 with reflecting plates are arranged to form a regular twenty-six angular shape near to a circle. The base 7 with the reflecting plates is composed of polygonal arched reflecting faces 8 formed of a quarter arch (90 degrees arch constituting the twenty-four angular shape) by arranging six ranks of the reflecting plates constituting the totally circumferential light- reflecting face 3 and arranging two files of the plates and arched base bodies 9 formed of a quarter arch (90 degrees arch constituting the twenty-four angular shape) at the surface provided at the inside of the polygonal arched reflecting faces 8.
