Apparatus and method for fault tolerant control of lighting network

The present invention provides a fault control apparatus of a lighting network. The fault control apparatus is comprised in each of a plurality of lighting units which are connected with each other through a network, and includes: a power source selection part which selects a power source to be supplied to a faulty lighting unit, by comparing a reference voltage with an output voltage sensed from power supply signals respectively inputted through a power supply part comprised in a lighting unit located before the faulty lighting unit and through the faulty lighting unit in case that the lighting unit has a fault; and a lighting control part controlling the driving of the faulty lighting unit by using the selected power source.
