Highway tunnel green lighting method effectively utilizing light energy

Abstract

The invention discloses a green lighting method for highway tunnels which effectively utilizes light energy. The inner wall of the tunnel is sprayed with energy-storage luminescent paint made of energy-storage luminescent materials, and the energy-storage luminescent reflective material is arranged in the tunnel along the contour of the tunnel. The energy-storage light-emitting reflective ring is equipped with energy-storage light-emitting reflective markings made of energy-storage light-emitting reflective materials on the tunnel road surface, and energy-storage light-emitting reflective protruding road signs made of energy-storage light-emitting reflective materials are set on the center line and both sides of the road surface. Energy-storage luminous reflective delineators made of energy-storage luminescent reflective materials are arranged on the tunnel walls on both sides. It has the characteristics of high efficiency, energy saving, environmental protection, safety and comfort, and compared with the tunnel mains lighting system, its facilities are simple, the construction is convenient, the cost is low, and it is easy to popularize and apply.

Description

technical field [0001] The invention relates to the technical field of road tunnel lighting, in particular to a road tunnel green lighting method that effectively utilizes light energy. Background technique [0002] With the increase of my country's comprehensive national strength and rapid economic development, my country's transportation infrastructure has been developed on a large scale, and expressways and road tunnels have also been greatly developed. According to the data released by the Ministry of Communications, by the end of 2015, the national highway mileage had reached 120,000 kilometers. By the end of 2014, 12,404 road tunnels with a length of 10,756.7 kilometers had been built, ranking first in the world. my country has become the world’s largest road tunnel , the most complex and fastest growing country. [0003] As a special road section of the highway, the road tunnel is a closed space except for the entrance and exit at both ends, and the illumination is ex...

Problems solved by technology

Especially during the day, when the driver enters the tunnel until he leaves the tunnel, he will encounter many visual problems: for example, before entering the tunnel, what the driver sees is a dark "hole". In the tunnel, due to the strong contrast between the high-brightness environment outside the entrance and the low-brightness inside the tunnel, as well as the driver's eyes' persistent visual impact on the bright environment, the driver cannot see the situation in the tunnel clearly in a short time; When it is close to the exit of the tunnel, due to the stimulation of high brightness outside the tunnel, it will reduce its vision (that is, the glare effect), and it will also make the driver unable to see the situation ahead clearly in a short time.

However, since road tunnels are mostly built between sparsely populated and inconvenient high mountains, and usually require 24-hour uninterrupted tunnel lighting, on the one hand, the equipment costs of the power line, the lighting equipment costs in the tunnel, and the construction costs and maintenance On the other hand, the electricity consumption is also high, and the electricity fee is also high, and the longer the tunnel mileage, the greater the electricity consumption, and the higher the electricity fee; in addition, using commercial electricity as tunnel lighting is not conducive to energy saving, nor It is not safe and environmentally friendly, and in the design specifications of road tunnels at home and abroad, there is a lack of regulations on lighting technology that effectively guides escape from accidents such as sudden fires
