| Zusammenfassung: | To provide an illumination system capable of improving the efficiency of work while looking at a display screen of electrical equipment.SOLUTION: The illumination system includes a light source and a control unit. The light source irradiates illumination light (first illumination light 101) to an irradiation surface S1. The irradiation surface S1 is located behind a piece of electrical equipment 5 that has a display screen 51. The control unit controls the light source. When viewing the display screen 51 and the irradiation surface S1 from the front, the length L1 in the left-right direction D2 of the irradiation area R1 formed on the irradiation surface S1 by the illumination light is more than twice the length L2 in the left-right direction D2 of the display screen 51. The control unit controls the light source so that the average brightness of irradiation area R1 is 100 cd/m2 or more and 350 cd/m2 or less.SELECTED DRAWING: Figure 3
【課題】電気機器の表示画面を見た状態での作業の効率化を図る。【解決手段】照明システムは、光源と、制御部と、を備える。光源は、照射面Ｓ１に対して照明光（第１照明光１０１）を照射する。照射面Ｓ１は、表示画面５１を有する電気機器５の後方に位置する。制御部は、光源を制御する。前方から表示画面５１及び照射面Ｓ１を見たときに、照明光により照射面Ｓ１に形成される照射領域Ｒ１の左右方向Ｄ２の長さＬ１は、表示画面５１の左右方向Ｄ２の長さＬ２の２倍以上である。制御部は、照射領域Ｒ１の平均輝度が１００ｃｄ／ｍ２以上で、３５０ｃｄ／ｍ２以下となるように光源を制御する。【選択図】図３ |
