The present invention relates to a traffic sign board which can be easily distinguished in the daytime and at night, more specifically, which can be easily recognized by flickering operation of a back light installed at an internal side of a frame at night. Moreover, in the daytime, as the back light is turned off, the sign board can be easily distinguished by a driver on a secluded country road or a sequestered road by flickering of LED light penetrating into a reflection sheet to be projected to the front.
본 발명은 주간과 야간에도 용이하게 식별되는 교통표지판에 관한 것으로, 보다 더 상세히 설명하면 야간에는 프레임 내측에 설치되는 백라이트의 점멸동작에 의해 표지판이 용이하게 인식되게 하고, 더불어 주간에는 백라이트가 오프로 전환되면서 반사시트를 관통하여 전면으로 투사되는 엘이디 빛의 점멸에 의해 한적한 시골길이나 외딴길에도 운전자들이 용이하게 표지판을 식별할 수 있도록 한 것이다.
