Impact of LED Color Temperatures on Perception Luminance in the Interior Zone of a Tunnel considering Fog Transmittance
Figure 16
The Y-axis on the left shows the levels of visual clarity using different CCTs under different fog concentrations and illuminance without fog. The Y-axis on the right shows the theoretical calculation results of Lf. (a) T = 100%, Li = 40lx. (b) T = 60%, Li = 20lx. (c) T = 100%, Li = 20lx. (d) T = 40%, Li = 20lx. Error bars indicate standard deviation.
