The reflective belt 3 is provided with a retroreflective material coating. The light source receives light reflected from the retroreflective material regardless of the angle at which the light strikes the coated surface of the retroreflective material. This is because the retroreflective material contains high refractive index glass beads or crystallites arranged in a region of thousands of tiny cells per square centimeter, which can reflect light back to the light source as it is, thereby allowing an observer near the light source to clearly see the target.

The retroreflective material coating is preferably a bright silver reflective material coating. The reflective strength of the bright silver reflective material can reach 500CPL, the reflective band 3 formed by the bright silver reflective material coating can be found at a distance of 300 meters, and the reflective band 3 can be seen to emit light in a field at a farther distance.

And a photoinduced energy storage fluorescent powder coating is arranged on the fluorescent strip 2. The light-induced energy storage fluorescent powder is prepared by storing light energy after the fluorescent powder is irradiated by natural light, daylight lamp light, ultraviolet light and the like, and slowly releasing the light energy in a fluorescent mode after the light irradiation is stopped, so that the light can still be seen at night or in a dark place, and the duration time is as long as several hours to dozens of hours.

The reflective belt 3 and the fluorescent belt 2 are arranged on the front face and the rear face of the warning plate 1, and the reflective belt 3 and the fluorescent belt 2 on the front face and the rear face are symmetrically arranged, so that the warning effect in two directions is realized.

When strong wind is blown, the area of the warning plate 1 is large, and the warning plate is easily subjected to large wind resistance, so that the warning plate 1 and a connecting structure on the warning plate 1 are damaged due to large stress. In order to solve the problem, warning board 1 is last and be located 3 regions of reflection of light band, and the interval is provided with a plurality of vents 4, vent 4 runs through warning board 1 front and back two sides, and when blowing, partial wind can pass from vent 4 to reduce warning board 1's windage, prolong warning board 1's life.
