Illumination control method and illumination control system and illumination system using the same
First Claim
1. An illumination control system comprising:
- a first type illumination controller which detects presence of a person in an illumination space to be illuminated by an illumination apparatus, the illumination apparatus being connectable to the first type illumination controller; and
a second type illumination controller which detects brightness in the illumination space, the second type illumination controller being connected to the first type illumination controller,wherein the second type illumination controller derives a degree of dimming based on the detected brightness, and notifies the degree of dimming to the first type illumination controller,wherein upon detecting the presence of a person, the first type illumination controller controls dimming of the illumination apparatus according to the degree of dimming notified from the second type illumination controller, andwherein the first type illumination controller includes a first image sensor and a first image processing unit and the second type illumination controller includes a second image sensor and a second image processing unit.

Abstract
An illumination control system includes a first type illumination controller which detects presence of a person in an illumination space to be illuminated by an illumination apparatus, the illumination apparatus being connectable to the first type illumination controller, and a second type illumination controller which detects brightness in the illumination space, the second type illumination controller being connected to the first type illumination controller. The second type illumination controller derives a degree of dimming based on the detected brightness, and notifies the degree of dimming to the first type illumination controller. Upon detecting the presence of a person, the first type illumination controller controls dimming of the illumination apparatus according to the degree of dimming notified from the second type illumination controller.
