The present invention relates to a road stud. More particularly, the present invention relates to a road stud that can be implemented in both directions and can provide optimal visibility. According to the present invention, a road stud comprises: a housing in which a receiving portion is formed; a lens having a groove formed on its lower surface; a PCB positioned below the lens; an LED positioned between the lens and the PCB; a first reflector which surrounds the LED and has an open upper side; a first refractive surface forming a portion of the groove; a second reflector positioned between the front and rear sides of the first refractive surface to form a portion of the groove; and a second refractive surface formed on an upper surface of the lens.
본 발명은 도로 표지병에 관한 것으로, 특히 양방향 구현이 가능하며 최적의 시인성을 제공할 수 있는 도로 표지병에 관한 것이다.
