A Solution to Highway Tunnel Lighting Without Artificial Light Source

Abstract

The invention discloses a method for achieving illumination of a highway tunnel without an artificial light source. The method is characterized by including the steps that no artificial light source is arranged in the whole highway tunnel, a sunshade with the segmented transition light transmittances is arranged outside a tunnel portal, and a hollow-out portion is arranged on the sunshade; the illumination problem in the tunnel is solved through the sunshade and reflecting signs in the tunnel. The danger level is reduced to the largest extent according to the eye adaptation time and economic conditions, the light-transmitting material and the light-transmitting area of a safety area are designed to gradually change according to the illumination transition rate which the eyes can adapt to naturally, so that a driver drives a car comfortably, and the method is the embodiment that highways are designed in the people-oriented principle. The method can be adaptive to long-sized highway tunnels at various areas, especially long-sized highway tunnels with large illumination changes, and has the advantages that the structure is simple, arrangement is convenient, and the use effect is good.

Description

technical field [0001] The invention relates to the field of highway traffic safety, in particular to the design and application of a tunnel entrance illumination transition section, which solves the lighting problem in a highway tunnel without a light source. Background technique [0002] At the entrance and exit of the current tunnel, due to the special structure of the tunnel, the brightness inside the tunnel is much lower than the brightness outside the tunnel during the day, and at night, the brightness inside the tunnel is much brighter than the brightness outside the tunnel, causing the driver every time Passing through the tunnel must adapt to the process of light adaptation and dark adaptation. Light adaptation is the process of coming from a dark place to a bright light. At first, when encountering a glare of light, you can’t see the outside situation clearly. It takes a while to get used to it. Dark adaptation is the process of gradually increasing the sensitivity...
