Problems solved by technology

Many reasons have reduced the quality of tunnel lighting, which has brought great safety hazards to tunnel driving; on the other hand, the existing environment in highway tunnels lacks a visual reference system, and the visual environment is relatively single, which makes drivers prone to visual fatigue. Not conducive to driving safety

Embodiment Construction

[0025] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0026] A method for optimizing ambient lighting in a highway tunnel provided by the present invention includes:

[0027] Coating energy-storage reflective layer on the inner wall between the entrance and exit of the tunnel;

[0028] The height curve of the energy-storage reflective layer is a sinusoidal curve. Through the above method, the lighting brightness in the tunnel can be effectively supplemented without increasing the lighting power and lighting fixtures, thereby effectively reducing the energy consumption of the entire tunnel lighting system. Moreover, it can establish a good visual reference system, enrich the visual environment in the tunnel, effectively relieve driving fatigue, improve the driver's visual comfort in the tunnel, and avoid driving safety hazards.

[0029] In this embodiment, the height curves of the high diffuse reflection layer and the en...

Abstract

The invention provides a method for optimizing ambient lighting in a road tunnel. The method comprises the steps that an energy storage reflective layer is applied on the inner side wall between the entrance and exit of the tunnel; the height curve of the energy storage reflective layer is a sinusoid; the illuminating brightness in the tunnel can be effectively supplemented under the premise of not increasing the illumination power and lighting fixtures, thereby effectively reducing the energy consumption of an entire tunnel lighting system, and a good visual reference system can be established to enrich the visual environment in the tunnel, thereby effectively alleviating the driving fatigue.

Description

technical field [0001] The invention relates to the traffic field, in particular to an optimization method for ambient lighting in a highway tunnel. Background technique [0002] With the development of national transportation construction, road construction, especially expressway construction, is accelerating day by day. In mountainous areas with complex terrain, road tunnels have the advantages of shortening road mileage, improving transportation efficiency, saving land and maintaining ecological environment. Since the beginning of the 21st century, the growth rate of the total mileage of road tunnels is 46.7%, which is much higher than the growth rate of 29% of the road itself, indicating that the construction and operation of road tunnels, especially super-long road tunnels and long tunnels, are becoming more and more important in the transportation industry. protrude. However, as the scale of the tunnel project becomes larger and larger, the operating electricity and ...
