An LED railway signal lamp system and an intelligent lighting unit (100) thereof. In the intelligent lighting unit (100), a control module (110) acquires, from fault detection modules (131, 132), detection results of corresponding LED lamp beads (210, 220) and loops thereof; when the detection results of the two LED lamp beads (210, 220) and the loops thereof meet a first condition, the control module controls, by means of two constant-current driving modules (121, 122), the two LED lamp beads (210, 220) to be alternately in a lit state; when the detection results thereof meet a second condition, the control module controls, by means of the corresponding constant-current driving modules (121, 122), the normal LED lamp beads (210, 220) to be constantly in the lit state, and gives an alarm by means of an alarm module (140); and when the detection results thereof neither meet the first condition nor the second condition, the control module controls, by means of a power supply control module (160), the two constant-current driving modules (121, 122) to stop operating, so as to trigger a first alarm (300) to give an alarm.
