<p>PROBLEM TO BE SOLVED: To provide an illumination controller by which desired illumination considering environmental circumstance can be obtained. SOLUTION: A brightness detection part 20 and a human body detection part 30 are installed in separation from a luminaiare 10 attached to a ceiling, etc. The brightness sensing are B of the brightness detection part 20 and the human body sensing area C of the human body detection part 30 can be determined independently from the illumination area A of the luminaire 10. The illumination load on the luminaire 10 is placed in its lightning condition, when the brightness detected by the brightness sensor of the brightness detection part 20 is larger than the preset brightness and a human body is detected by the human sensing sensor of the human body detection part 30.</p> |
