Among the four visual of several problems in road lighting
one Among the concept of visual
two spectral luminous efficiency of V (visual cells λ) And V '( λ) Curve of the luminous flux from V ( λ) Calculated.
V( λ) And V '( λ) Spectral luminous efficiency, a maximum of 1. Km• V( λ) And Km 'V' ( λ) Spectral luminous efficiency. Maximum is respectively: 683 lm/W and 1700 lm/W
in 0. 001 - 3 CD/m2 in the middle of the visual segment between the spectral luminous efficiency of the change is continuous. Depending on the brightness of the eyes to adapt to the level.
