LOW-POSITION ILLUMINATION DEVICE, AND ROAD ILLUMINATION METHOD WITH LOW-POSITION ILLUMINATION DEVICE
To provide a low-position illumination device that easily equalizes illuminance on a back side and a front side in a width direction on a road.SOLUTION: A low-position illumination device 1 is installed at a low position beside a road 2 comprising one or more lanes 5. The low-position illumination device 1 comprises a first illumination unit, and a second illumination unit. The first illumination unit applies first illumination light C1 to a back side in a width direction M2 of the road 2 on the road 2 out of the one or more lanes 5. The second illumination unit applies second illumination light C2 to a front side in the width direction M2 on the road 2 out of the one or more lanes 5.SELECTED DRAWING: Figure 1
【課題】道路における幅方向の奥側と手前側で照度を均一にし易い低位置照明装置を提供する。【解決手段】低位置照明装置１は、１つ以上の車線５を有する道路２の脇の低位置に設置される低位置照明装置である。低位置照明装置１は、第１照明ユニットと、第２照明ユニットと、を備える。第１照明ユニットは、１つ以上の車線５のうち、道路２における道路２の幅方向Ｍ２の奥側に第１照明光Ｃ１を照射する。第２照明ユニットは、１つ以上の車線５のうち、道路２における幅方向Ｍ２の手前側に第２照明光Ｃ２を照射する。【選択図】図１
