The present invention relates to road traffic signs. More specifically, the present invention relates to a variety of road traffic signs that can be installed on the road for the driver to function as a direction guidance or lane guidance, and more particularly relates to a sign that can contribute to the safe driving of the car by increasing the brightness will be.

[Background of invention]

Until now, various road traffic signs such as direction guidance signs installed on curve roads and lane guidance signs installed around a construction site have been developed in various forms.

It developed from the simple coloring method that paints the sign contents of the signs, and the luminous paint was applied to ensure safe driving at night, and the light emitting diode (LED) was attached to the sign surface to provide brightness at night as well as during the day. The method of increasing has been used, and the method of attaching a light bulb has been used in places where electricity can be temporarily used, such as a road construction site.

However, the use of electricity by attaching light bulbs is not only power-consuming, but also expensive to install, and is only partially used in specific designations due to the many defects that can be installed only in specific areas. For example, it is almost impossible to install electric road traffic signs on curved roads in mountainous areas. In addition, in the method of attaching the LED, solar energy can be used as electric energy using a solar cell and a storage battery. However, since the LED is attached to the sign surface, it cannot exhibit sufficient brightness. In particular, automobiles are traveling at a relatively high speed, and signs that have a sufficient distance of view are required for the driver of the vehicle to recognize the surrounding situation from the vehicle. However, a sign having an LED attached to the surface thereof has a low luminance, and thus a sufficient viewing distance cannot be obtained.

Therefore, the present inventors have developed a road traffic sign having a sufficient brightness so that a driver of a vehicle can recognize a surrounding situation of a road at a distance required for safe driving.

[Purpose of invention]

It is an object of the present invention to provide a road traffic sign with sufficient brightness so that a driver of a motor vehicle can recognize the surrounding conditions of a road at a distance necessary for safe driving.

Another object of the present invention is to provide a road traffic sign that reflects and diffracts the light emitted from the LED to increase the brightness.

Another object of the present invention is to provide a road traffic sign which is easy to install by using LED.

Another object of the present invention is to provide a road traffic sign that can contribute to safe driving by increasing the brightness.

The above and other objects of the present invention can be achieved by the present invention described below.
