<P>PROBLEM TO BE SOLVED: To provide a lighting control system capable of more accurately calculating power consumption when a lighting fixture with an initial illuminance correction function is used. <P>SOLUTION: A lighting management device 2 of a lighting control system 1 suppresses power consumption in an initial stage of lamp replacement according to the model of a lighting fixture 5 with the initial illuminance correction function and a light control level and performs correction for gradual increase of the power consumption to keep a lamp at the same brightness as a cumulative use time increases. The lighting management device 2 can calculate the power consumption more accurately because it calculates it based on the power consumption after this correction and a cumulative lighting time per light control level. <P>COPYRIGHT: (C)2012,JPO&INPIT |
