example

[0026] This example relies on the Longtoushan Tunnel, the key project of the Tongsan and Beijing-Zhuhai National Highway around the eastern section of the Guangzhou Ring Road (Guangzhou Zhujiang Huangpu Bridge), to design the highway tunnel lighting system. Longtoushan Tunnel is currently the longest two-way separated eight-lane highway tunnel in China. Design driving speed of Longtoushan Tunnel: V=100km / h=27.78m / s. The lighting design brightness is shown in Table 2: (The ambient brightness outside the cave is taken as 4000cd / m2). The lighting of Longtoushan Tunnel is divided into five sections according to the driving direction. That is, the entry section, the transition section I, the transition section II, the middle section, and the exit section.

[0027] refer to figure 1 , figure 1 It is a schematic diagram of the arrangement of lamps in the highway tunnel lighting system in the prior art. Among them, 11 is a ceramic metal halide lamp, 12 is a fluorescent lamp, 13 is ...

Abstract

The invention discloses a light source illumination system for a road tunnel. In the illumination system, illumination light sources with color rendering indexes more than or equal to 75 are used and are white light light-emitting diode (LED) lamps, and light beam angles for arranging the illumination light sources in the tunnel are 53 to 123 degrees. The road tunnel is sequentially divided into an entrance section, a transitional section, a middle section and an exit section; the white light LED lamps comprise basic illumination lamps and strengthening illumination lamps; the strengthening illumination lamps are arranged in the entrance section, the transitional section and the exit section; and the basic illumination lamps are arranged in the middle section. LED light source illumination technology is used in the all line of the road tunnel, and due to consideration to parking sight distance in illumination control, the probability of accidents is reduced; the white light LED lamps have high color rendering performance, so that driving comfort is improved, and harm to human vision is avoided; and energy sources can be greatly saved after illumination brightness control is used.

Description

technical field [0001] The invention relates to the technical field of road tunnel light source lighting, in particular to a road tunnel light source lighting system. Background technique [0002] Safety, environmental protection, high efficiency, and energy saving are the goals pursued by highway engineering construction, especially in the operation and management of highway tunnels. As a special structure of the road, the road tunnel, in order to ensure the driving environment conditions, the operation cost of the tunnel lighting infrastructure, which is indispensable for the operation of the long road tunnel, is high. According to the survey of the tunnel management departments in Guangdong, Fujian, Zhejiang, Chongqing and other places where there are many road tunnels, the cost of tunnel ventilation and lighting has become a heavy burden in the operation of road tunnels. At the same time, there is a contradiction between the safety and energy saving of the tunnel lighti...
