To provide luminaire capable of showing properly a light effect, which is viewed as if light flows smoothly by few optical sources.SOLUTION: Luminaire includes a long transparent material 10, a first light source 20A for irradiating light to a first end face of the transparent material 10, a second light source 20B for irradiating light to a second end face of the transparent material 10, and a control device. The control device increases luminance of the first light source 20A from 0 to a first set luminance and maintains it, and then decreases it to 0, and increases luminance of the second light source 20A from 0 to a second set luminance and maintains it, and then decreases it to 0.SELECTED DRAWING: Figure 6

    【課題】少ない光源によって光が円滑に流れるように見える照明効果を好適に奏でる照明装置を提供する。【解決手段】照明装置は、長尺の導光体10と、導光体10の第1の端面に光を照射する第1の光源20Aと、導光体10の第2の端面に光を照射する第2の光源20Bと、制御装置を備える。制御装置は、第1の光源20Aの輝度を0から第1の設定輝度まで増加させて維持した後、0まで減少させ、第2の光源20Bの輝度を0から第2の設定輝度まで増加させて維持した後、0まで減少させる。【選択図】図6
