An LED signal control system and an LED signal used in the same are provided to secure a safe drive of a train by monitoring and controlling an operation state of a LED signal in a control room. A signal control part(103) detects a state of an LED signal(104), and generates a detecting signal. A current detection relay(102) receives the detecting signal from the signal control part. In case a light-out ratio of the LED signal is more than a predetermined ratio, the current detection relay switches a power source of the LED signal from a main power to a sub power. The current detection relay transmits a power input signal to the signal control part. A control room(101) monitors a state of the LED signal based on the detecting signal of the signal control part. |
