The present invention relates to an airfield light system which includes: a constant current controller which outputs a constant current; a plurality of insulating transformers which are electrically connected to the constant current controller and supply power; and a plurality of individual equalizers which are electrically connected to each insulating transformer and control the on/off of a lamp. The individual equalizer includes a first alternating and direct current converter which is connected to the insulating transformer, and an open sensing interface which senses the electrical open state of the lamp.
