PROBLEM TO BE SOLVED: To provide a plant lighting system comprising a lighting device for plant appreciation/observation in addition to a lighting device for raising plants, which suppresses the degradation of environment for raising the plants at the time of appreciation or observation.SOLUTION: A lighting system (14) comprises a lighting device (20A) for raising plants and a lighting device (20B) for plant appreciation. The lighting device (20A) for raising the plants irradiates the plants with light having luminescence peaks in a blue wavelength region and in a red wavelength region, respectively. The lighting device (20B) for plant appreciation includes: luminous elements (170B) which emit light in a blue wavelength region: a green fluorescent body G which emits fluorescence in a green wavelength region by being excited by light from the luminous elements (170B) and red fluorescent body (R) which emits fluorescence in a red wavelength region by being excited by light from the luminous elements (170B). A blue/red ratio of the lighting device (20A) for raising the plants and that of the lighting device (20B) for plant appreciation are matched or substantially matched to each other.COPYRIGHT: (C)2015,JPO&INPIT【課題】育成照明装置の他に観賞/観察照明装置を備えた植物照明システムにおいて、観賞または観察時に植物育成環境が劣化することを抑制する。【解決手段】照明システム(14)は、育成照明装置(20A)と観賞照明装置(20B)とを備える。育成照明装置(20A)は、青色波長領域と赤色波長領域との各領域にて発光ピークを有する光を植物に照射する。観賞照明装置(20B)は、青色波長領域の光を発光する発光素子(170B)と、発光素子(170B)からの光にて励起して緑色波長領域の蛍光を発する緑色蛍光体(G)と、発光素子(170B)からの光にて励起して赤色波長領域の蛍光を発する赤色蛍光体(R)とを備える。育成照明装置(20A)のBR比と観賞照明装置(20B)のBR比とを一致または略一致させる。【選択図】図2
