<P>PROBLEM TO BE SOLVED: To provide a luminaire that improve human's visibility after lighting a light source by emitting light matching the human's visibility over the entire irradiation range of the light source. <P>SOLUTION: The luminaire includes an illumination part 1 equipped with a plurality of light source parts 11 which emit light by a plurality of divided areas 71 of the irradiation range, and change wavelength constitution of the light, a movement detection part 6 which detects a lighting state of another luminaire, a storage part 4 which stores internal data representing lightness of each area 71 only with the light that the light source parts 11 emit, and external data representing lightness of each area 71 only with light that the another luminaire emits by lighting states of the another luminaire, an operation part 3 which computes the ratio of a long-wavelength component and a short-wavelength component of the light that the light source parts 11 emit based upon the sum of the internal data and external data corresponding to a detection result of the movement detection part 6, and a control part 5 which controls the wavelength constitution of the light that the light source parts 11 emit based upon operation results of the respective areas 71 by the operation part 3. <P>COPYRIGHT: (C)2012,JPO&INPIT |
