PURPOSE:To flexibly respond respectively to each time zone of illumination, the presence or absence of a person, a user's request, etc., so as to make each adequate illumination by having load control terminal units which respectively light and extinguish each of illuminators or adjust its quantity of light according to an illuminating condition set in response to each of combinations consisting of detection results given from human-body detecting means, a light-and-shade detecting means and a time ticking means. CONSTITUTION:The title device has human-body detecting means 8a, 8b which respectively detect the presence or absence of a human body, a light-and-shade detecting means which detects light and shade conditions, and a time ticking means 4 which detects a preset time. The device has also load control terminal units 6a, 6b which respectively light and extinguish each of illuminators or adjust its quantity of light according to an illuminating condition set adequately in response to each of combinations consisting of detection results given from the human-body detecting means 8a, 8b, the light-and-shade detecting means and the time ticking means 4. Accordingly, each of the illuminators is lit and extinguished or subjected to its light adjustment under each of illuminating conditions set in response to various circumstances depending upon the combinations consisting at their respective detection results, and therefore a carefully thought-out illumination control is made. This process eliminates the need for any complicated wiring, and yet each adequate illumination can be made while the device flexibly responds respectively to each time zone of illumination, the presence or absence of a person, a user's request, etc. |
