(JA) 照明装置
Abstract
(EN)
This illuminating device is provided with: a first light source that outputs visible light; a scattering member that scatters the visible light outputted from the first light source; and a second light source that outputs, to the scattering member, light having a color temperature that is higher than that of the light the first light source outputs, said second light source outputting the light from a direction different from the direction in which the first light source outputs the light.
(FR)
La présente invention concerne un dispositif d'éclairage qui comprend : une première source de lumière qui émet de la lumière visible ; un élément de diffusion qui diffuse la lumière visible émise par la première source de lumière ; et une seconde source de lumière qui émet, vers l'élément de diffusion, de la lumière ayant une température de couleur qui est plus élevée que celle de la lumière émise par la première source de lumière, ladite seconde source de lumière émettant la lumière à partir d'une direction différente de la direction dans laquelle la première source de lumière émet la lumière.
(JA)
照明装置は、可視光を照射する第一光源と、第一光源が照射する可視光を散乱させる散乱部材と、第一光源とは異なる方向から、拡散部材へ、第一光源よりも色温度が高い光を照射する第二光源とを備える。
