The traditional lighting
technology is insufficient for improving the quality of tunnel light
environments; hence, it is necessary to further improve the lighting theory and
technology based on the coupling effect of the driver-vehicle-tunnel lighting environment. To
solve the critical scientific problem of the nonequivalent characteristics of
the tunnel lighting load and the biological perception effect during tunnel
operation, the authors propose a construction concept of equivalent lighting
for tunnel lighting environments. Subsequently, from the perspective of
reasonable matching of lighting luminaires and sidewall materials, the
equivalent lighting theory is demonstrated through simulation experiments, real
vehicle experiments, and theoretical calculations. Finally, the theoretical
research framework of equivalent lighting for improving the biological
perception effect and reducing the lighting environment load (one increases and
the other decreases) is summarized. The results show the following: (1) Reasonable
matching of physical parameters (e.g., reflection of sidewall materials and
layout of the luminaire) can maximize road surface illumination by 25% and 21%
and the total uniformity by 9% and 15% in the threshold and middle zones,
respectively, and thus, can reduce the 〖HJ1.5mm〗number of luminaires by 33%. (2) Proper choice of physical
parameters (such as spectrum and color temperature) can reduce the reaction
time of the driver by up to 6% and improve the visibility of small targets by
26.2%. (3) Changes in physical parameters (such as different types of sidewall
materials) can reduce the driver′s heart rate,
breathing rate, fixation time, saccade range, and pupil area, while increasing
the electroencephalographic power; further, the change range is smoother. (4)
By further studying the equivalent action mechanism of different physical
indicators on driver information perception, the tunnel lighting load can be
effectively reduced, and the biological perception effect can be improved.
