Green lighting technology for road tunnel

Abstract

The invention discloses a green lighting device for a road tunnel. An area light source plate is arranged on the wall surface of the arch wall of the tunnel at the height of 2-4 m; reflection induction marks are arranged on the area light source plate of the wall surface and the vault part of the tunnel. Due to the fact that the energy-saving, safe and environment-friendly area light source plateis installed on the wall face of the arch wall of the tunnel, the area light source plate can serve as an area light source illuminating lamp and a decorative plate with an attractive and stain-resistant wall face; since illumination and decoration are combined, construction cost can be saved, and later-period operation cost is reduced; the energy-saving, safe and environment-friendly reflection induction marks are arranged at the vault part of the tunnel; under the irradiation of automobile lamps, the phenomena of black holes and blind light, confronted by a driver at the entrance and exit ofthe tunnel can be reduced or eliminated, the section of the contour surface of the vault of the tunnel can be clearly reflected and reflected, a light environment effect in the tunnel is improved, the darkness of the vault is eliminated, the psychological pressure of the driver in a dark chamber is reduced, and operation safety is improved.

Description

technical field [0001] The invention relates to a lighting technology, in particular to a green lighting device for road tunnels. Background technique [0002] The road tunnel is a dark environment. In order to ensure the safety of operation, 24-hour lighting is required, which consumes a lot of energy. The main reason why highway tunnels need lighting is to reduce the rapid changes in the pupils of the human eye caused by the difference in light intensity inside and outside the tunnel when vehicles enter the tunnel from light to dark and leave the tunnel from dark to light at a certain speed during the day. The phenomenon of "black hole" and "blind light"; the second is to ensure and improve the visual distance of the driver in the dark environment, to ensure that the driver can take emergency braking when they find obstacles in the driving process, and in the habitual The lighting brightness required for a parking sight distance that can just stop the car before rushing t...

AI Technical Summary

Problems solved by technology

[0003] The problem is that from the perspective of reducing the "black hole" and "blind light" phenomena caused by the rapid change and oscillation of the pupil of the human eye caused by the difference in light intensity inside and outside the tunnel, experiments have shown that it is necessary to ensure its vision within the range of speed and distance of 0.25 seconds. The change of light intensity is less than 30 times, and the current industry technical specifications cannot meet the safety requirements under extreme geographical conditions, such as under the sunny conditions in summer in central and western my country, or under the snowy conditions in winter in the areas north of the Yellow River in my country, on roads The brightness outside the hole is relatively large when driving. In many cases, the technical parameters given by the current industry standards cannot eliminate "black holes" and "blind light", which poses a major hidden danger to safe driving.
