    • An illuminating device able to easily visualize a pedestrian, etc. on a footway by the driver of an automobile is provided. The illuminating device has a footway side light source portion for irradiating light of spectral characteristics rich in blue-green color light to the footway, and a roadway side light source portion for irradiating light of spectral characteristics rich in green-red color light to a roadway. Further, the spectral characteristics of the light irradiated from the footway side light source portion are set such that a value Ip obtained by the following formula (1) is greater than a value IC obtained by the following formula (1) from the spectral characteristics of the light irradiated from the roadway side light source portion. I = ∫ a b ⁢ S ⁡ ( λ ) · V ′ ⁡ ( λ ) ⁢ ⁢ ⅆ λ ∫ 380 780 ⁢ S ⁡ ( λ ) · V ⁡ ( λ ) ⁢ ⁢ ⅆ λ ( 1 )
    • 提供能够容易地通过汽车驾驶员在行人路上观察行人等的照明装置。 照明装置具有用于将具有丰富的蓝绿色光的光谱特性的光的光照射到人行道的行人侧光源部,以及用于将具有丰富的绿色 - 红色光的光谱特性的光照射到道路的道路侧光源部 。 此外,从行人侧光源部照射的光的光谱特性被设定为使得通过下式(1)获得的值Ip大于通过下式(1)获得的值IC从光谱特性 从道路侧光源部照射的光。 I =∫ab S⁡(λ)。 V'⁡(λ)⁢λ∫380 780 S⁡(λ)。 (⁡(λ))ⅆλ(1)
