LIGHTING SYSTEM

Japanese Patent JP3921774

B2

PROBLEM TO BE SOLVED: To provide a lighting system capable of controlling a light source without erroneous operations when illuminance in the surroundings is reduced.
SOLUTION: This lighting system is provided with an illuminance sensor 1 detecting the illuminance level in the surroundings, a control part 3 sending lighting information of a light source 6 to a lighting device 5 in accordance with the results of detection of the illuminance sensor 1, and the lighting device 5, and the control part 3 inhibits inputting of the results of detection of the illuminance sensor 1 for a fixed period of time from the time when the illuminance level in the surroundings drops below a first predetermined value. Consequently, it is possible to prevent erroneous operations due to changes in the sunrise time depending on seasonal changes because it is possible to inhibit inputting of the illuminance sensor 1 unitl just before the sunrise and release inputting inhibition a little before the sunrise by constituting the device in this way. That is, it is possible to prevent erroneous operations due to incidence by external disturbance light during a midnight mode and provide the illumination device having high performance.
