In the present invention, the road name information board is composed of a light guide plate that emits light on its own to improve visibility, and solar panels that supply power to the light guide plate are formed in a row along the longitudinal direction above the light guide plate to create a sense of unity, and the road name can be printed directly on the ground. It relates to a road name information device having a floor display unit equipped with a display beam projector to facilitate the identification of the road name by drivers or pedestrians.

In general, road name information boards that provide geographic information about roads provide the convenience of driving vehicles while checking their destination. They can be considered road and traffic safety facilities that guide drivers to accurately recognize their destination. . These road name signs are traffic information facilities that are installed on the edge of the road or on the sidewalk to provide guidance to drivers and pedestrians about the road or area by indicating the direction of vehicle movement and guidance using various types of letters, symbols, or shapes depending on the purpose. It fulfills its role sufficiently.

However, since conventional road signs do not have a self-luminous function, they must have a light source to be identified, and since they are hung at a certain height from the ground, there is a problem in that it is difficult for drivers to check the road signs at night on general national roads without street lights. Considering this, road names and road information boards are painted with luminous materials to make them easy to identify even at night. However, luminous materials have the disadvantage of low visibility due to wear and tear due to long-term use and insufficient light.
