PROBLEM TO BE SOLVED: To provide an illumination system capable of allowing a user to check an illumination position of near infrared light.SOLUTION: An illumination system 100 for illuminating perishable foodstuff F with light, includes: a white light source 210 which emits white light W； and a near infrared light source 220 that, in an arrangement surface A on which the perishable foodstuff F is arranged, emits a near infrared light IR which has at least one luminescence peak in a wavelength area of 700-1100nm covering at least a part illumination range of the white light W.SELECTED DRAWING: Figure 1【課題】近赤外光の照射位置が確認しやすい照明システムを提供する。【解決手段】生鮮品Ｆに光を照射する照明システム１００であって、照明システム１００は、白色光Ｗを発する白色光源２１０と、生鮮品Ｆが配置される配置面Ａにおいて、白色光Ｗの光照射範囲の少なくとも一部を覆うように、７００ｎｍ以上１１００ｎｍ以下の波長領域に少なくとも一つの発光ピークを有する近赤外光ＩＲを発する近赤外光源２２０と、を備える。【選択図】図１
