    Nanjing Yangtze River Crossing Tunnel Lighting Project

    I. Project Overview

    On May 28, 2010, the Nanjing Yangtze River Tunnel was opened to traffic. As one of the important passages connecting Nanjing Jiangnan and Jiangbei, it is of great significance to change the unity of cross-river traffic and promote the development of Jiangbei. The total length of the tunnel is 6,156 meters. It is constructed according to the scale of the six-lane urban expressway. The designed speed is 80 km/h, and the one-way traffic is more than 2400 vehicles/hour.

    Second, the introduction of lamps

    The tunnel uses 400W high-pressure sodium lamp, 250W high-pressure sodium lamp, 100W high-pressure sodium lamp, a total of more than 500 sets, 2 ?— 58W three anti-lights more than 2000 ???.

    Basic lighting 2*58W fluorescent light source tunnel light, installed on both sides of the tunnel, installation height 4.5 meters, lamp spacing 6 meters. The emergency lighting is set every 48 meters, the lamp position is the same as the normal lighting, and it is used as a normally-on lamp when it is normal.

    The entrance section of the enhanced lighting adopts 400W high-pressure sodium lamp, the installation height is 4.6m, the spacing of the lamps is 1.5m; the transition I section uses 400W high-pressure sodium lamp, the installation height is 4.6m, the lamp spacing is 4.5m; the transition II section uses 250W high-pressure sodium lamp, the installation height is 4.6m, The distance between the lamps is 9 meters; the transition III is 100W high-pressure sodium lamps, the installation height is 4.6 meters, the distance between lamps is 18 meters; the outlet section is 400W high-pressure sodium lamps, the installation height is 4.6 meters, and the distance between lamps is 9 meters. (In the actual installation and commissioning process of the tunnel, the installation position of the lamp is slightly adjusted according to actual needs.)

    Third, the actual lighting effect
