본 발명은 관리편의성이 향상된 LED 표지판에 관한 것으로서, 특히, 교체작업에 따른 교통혼잡을 유발하지 않고, 교체비용이 소요되지 않는 효과가 있다.

    The present invention relates to an LED sign with improved management convenience, and in particular, does not cause traffic congestion due to replacement work, and has an effect that replacement cost is not required. The LED sign includes: a guide plate having a guide display unit formed on a front thereof; an LED light source for emitting at least a guide display of the guide plate; an auxiliary LED light source disposed adjacent to the LED light source; a light source current detection unit for sensing a current input to the LED light source; and a power bypass unit for supplying power to the auxiliary LED light source when no current is input to the LED light source by the light source current detection unit.
