Document Type and Number:
Japanese Patent JP6266373
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an energy saving illumination system with high efficiency, capable of obtaining natural and accurate awakening effect.SOLUTION: In an illumination system 10, a time integration value of the illuminance about radiation light emitted from light sources 32a, 32b for illumination is calculated, and the light sources 32a, 32b for illumination are made to emit light until the time integration value of the illuminance reaches pre-set thresholds Ta, Tb, Tab. As a result, natural and accurate awakening effect can be obtained and an energy saving illumination system with high efficiency can be provided.
