Illumination system and illumination apparatus

摘要

An illumination system includes a plurality of illumination apparatuses, each of the illumination apparatuses including a light source, a detection sensor for sensing presence and absence of a moving object, a wireless communication unit for transmitting a sensing signal of the detection sensor to other illumination apparatuses and for receiving a sensing signal from other illumination apparatuses and a control unit for controlling an output of the light source based on the sensing signal of the detection sensor or the sensing signal transmitted from other illumination apparatuses. If the detection sensor of one of the illumination apparatuses senses the moving object, at least one of remaining illumination apparatuses is controlled together by the sensing signal wirelessly transmitted from said one of the illumination apparatuses.

1. An illumination system, comprising:
a plurality of illumination apparatuses, each of the illumination apparatuses including a light source, a detection sensor for sensing presence and absence of a moving object, a wireless communication unit for transmitting a sensing signal of the detection sensor to other illumination apparatuses and for receiving a sensing signal from other illumination apparatuses and a control unit for controlling an output of the light source based on the sensing signal of the detection sensor or the sensing signal transmitted from other illumination apparatuses, wherein if the detection sensor of one of the illumination apparatuses senses the moving object, at least one of remaining illumination apparatuses is controlled together by the sensing signal wirelessly transmitted from said one of the illumination apparatuses, wherein the control unit of one of the illumination apparatuses controls the light source of said one of the illumination apparatuses so that an illuminance of the light source of said one of the illumination apparatuses when said one of the illumination apparatuses is in an area forward of the moving object in a moving direction of the moving object and an illuminance of the light source of said one of the illumination apparatuses when said one of the illumination apparatuses is in an area behind the moving object in the moving direction are different each other, and wherein the illumination system further comprises a sensing device for sensing presence and absence of the moving object in a sensing range differing from a sensing range of the detection sensor and for wirelessly transmitting a sensing signal to at least one of the illumination apparatuses.
