<P>PROBLEM TO BE SOLVED: To obtain appropriate lighting with less energy consumption by taking outdoor light indoors. <P>SOLUTION: A method for operating this lighting system comprises: a step S1 of regularly referring to a database control logic; a step S2 of controlling a color temperature of ambient lighting to meet a predetermined color temperature corresponding to a time zone; a step S3 of obtaining integration values of outdoor light and indoor light, respectively; and a step S4 of controlling the slant angle of an electric blind and the illuminance intensity of ambient lighting as to make a outdoor-light-to-indoor-light ratio meet to a target ratio of the database control logic, wherein actual entry light into a room through a window is adjusted so as to meet a predetermined ratio of outdoor light by the electric blind even if outdoor light strongly enters at a low angle, and at the same time, the illuminance intensity of ambient lighting is adjusted, thereby outdoor light and indoor light can be dynamically mixed in a balanced manner, and therefor indoor lighting taking in outdoor light is appropriately performed. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
