Natural light-based tunnel lighting system

Abstract

The invention belongs to a natural light-based tunnel lighting system, comprising a solar energy light reducing gallery and an LED (Light-Emitting Diode) lighting transition section; a solar power generation system of the solar energy light reducing gallery directly supplies LED lamps of the LED lighting transition section, the solar energy light reducing gallery comprises a gallery bracket, thin film solar power generation panels embedded in the top of the gallery bracket, ventilation sound absorbing panels embedded in the upper part and lower part of the side surfaces of the gallery bracket and tempered glass embedded in the middles of the side surfaces of the gallery bracket, and the light transmittance of the thin film solar power generation panels is reduced along with the approach of the gallery to a tunnel port according to a tunnel entrance and exit adaptive curve; and the LED lamps of the LED transition section are connected with the thin film solar power generation panels of the solar energy light reducing gallery. The lighting system integrates gallery light reducing and solar power generation technologies, adopts low-cost solar thin films suitable for a road tunnel environment instead of the gallery used at the parts of entrance and exit sections of the tunnel, omits investment of lamps at the entrance and exit sections and saves power supply of the entrance and exit sections with the largest lighting power consumption.

Description

technical field [0001] The invention relates to a tunnel lighting system based on natural light. Background technique [0002] my country's road tunnel construction has gradually begun to expand to high-altitude areas, especially in Sichuan Province under the background of the construction and development of the western comprehensive transportation hub of "constructing hubs, opening channels, improving road networks, and supporting highlands", the road network continues to advance to the western Sichuan plateau, It is necessary to adopt a large number of tunnel engineering schemes to shorten the route mileage, avoid unfavorable geological diseases (such as ice and snow, landslides, mudslides, etc.), optimize the horizontal and vertical line indicators of the route, protect the ecological environment, and improve transportation efficiency. Summarizing the high-altitude road tunnels on the Western Sichuan Plateau in Sichuan Province, there are mainly the following characteristi...

[0004] Second, the conflict between low traffic volume and high construction cost

Western Sichuan is sparsely populated, relatively scattered, and the traffic volume is small. In the high-altitude area of ​​Western Sichuan, the mountains are high and the valleys are deep. The proportion of tunnels in the route is extremely high, and the traffic volume during the op
