Hereinafter, the reflective pieces described above will be described again in detail.

According to the present invention, in order to provide a reflective piece that exhibits a desirable reflectivity, a single type of reflective piece having the same shape and reflection angle as the shape of the reflective surface of the reflective piece is used to change only the arrangement direction of the reflective surface so as to be regular (repeatable). Etc.), or a plurality of heterogeneous reflecting pieces of which the shape and reflecting angle of the reflecting surface are not the same, depending on the shape of the reflecting surface, the reflecting angle, or the arrangement direction of the reflecting surface (repetition, etc.) The reflector is configured to be distributed by distributing or randomly mixing without giving a specific form.

It can be freely configured according to the reflectivity required for the reflector or according to the aesthetic demand required for the reflector.

In addition, as the above-described angle of the reflecting surface or the shape and size of the reflecting surface change the retroreflectivity of the light at a certain distance, by selecting the shape of the reflecting piece which can provide the desired reflectivity according to the purpose of the reflecting part, It will be possible to provide a road sign that can achieve the most desirable effect.

In general city roads, many cars run simultaneously.

As many light sources including street lights and signboards except for headlights are secured, even a road sign bottle installed at a distance based on the light source of the headlights of the vehicle is smoothly reflected back by the preceding vehicle or other light sources. It's possible to get enough time to grasp the status,

Since the headlight of the vehicle may act as the only light source on roads where the driving of vehicles such as national roads is extremely limited,

Only the headlights of the vehicle may recognize only road signs within a certain distance.

Therefore, they are in a dangerous environment because they do not have enough time to clearly judge the condition of the road.

Therefore, in order to prevent the occurrence of such dangerous situation at this time,

The reflector is formed by using a reflection piece composed of a plurality of reflection surfaces having different incidence angles and reflection angles.
