Abstract

A lighting indication device is connected to a plurality of LED sensing lightings via a lighting network. A receiver receives sensing information from at least one of the plurality of LED sensing lightings via the lighting network, and determines whether the sensing information includes a warning code. A warning position identifier identifies a position of an LED sensing lighting in which warning occurs based on the sensing information when the sensing information includes the warning code. A path setting unit generates a warning lighting signal for indicating warning generation information and an escape guide lighting signal indicating an escape guide direction based on the position of the LED sensing lighting in which the warning occurs. A transmitter transmits the warning lighting signal and the escape guide lighting signal to the plurality of LED sensing lightings via the lighting network.
