Embodiment
[0033] Embodiment: The specific implementation process of the above-mentioned closed-loop feedback control method for tunnel lighting is as follows:
[0034] S1. The luminance L outside the cave can be directly detected by the luminance meter, infrared detector, and coil vehicle detector. 20 (S), traffic flow, vehicle speed, information on whether the vehicle is available or not. Luminance values are calculated from the collected information according to the specification.
[0035] S2. According to the road tunnel lighting design rules, the entrance section is divided into two lighting sections, and the corresponding brightness calculation formula is:
[0036] L th 1 = k × L 20 ...
