The emergency power supply should be installed at the tunnel power supply. The power supply of the tunnel does not meet the power requirements of the tunnel lighting. If the dual power supply is hardly connected as required, the engineering cost is too high. Therefore, it is recommended to install an uninterruptible power supply unit at the distribution box. The power supply time of the power supply can be maintained for more than 15 minutes, so that the tunnel light can not be extinguished immediately when the utility power is cut off, and the buffering time is provided for the power supply of the tunnel light power to the diesel generator set, and the power supply is cut off at the tunnel entrance. The power outage information is given to make the driver of the motor vehicle prepare and reduce the possibility of accidents. This is a major event that affects the personal safety of the citizens. The original design did not specify specific requirements for the luminaires in the tunnel. The smoke in the tunnel is relatively thick. When the tunnel is cleaned, the protection level of the tunnel lamp should be more than IP65. The light source should use a high-pressure sodium lamp with good penetration. Other problems to be noticed in tunnel lighting: The tunnel light arrangement should be well inductive but should not be placed in the middle of the tunnel to avoid excessive impact on vehicle traffic in the tunnel during maintenance. The installation distance of the luminaire should be chosen properly, and no flash effect should occur. There should be a tunnel sign and a height limit sign at the entrance to the tunnel. LED lighting area exhibition and lighting new products, new technology promotion activities; Chongqing Lighting Society annual meeting activities; Chongqing lighting project achievements; night lighting seminars. Chongqing is one of the earliest cities in China to build nightscape lighting. In recent years, with the vigorous development of urban construction in Chongqing, the construction of urban nightscapes has been highly valued by the Chongqing Municipal Government, invested heavily in the development and management of night lighting management regulations. Therefore, the implementation of the construction of a large number of urban public lighting has enabled the market demand for urban lighting technology products to continue to expand.
