Intelligent tunnel LED lighting era
Since entering the 21st century, the development of LED lighting technology has become increasingly strong, LED lighting gradually occupy most of the tunnel lighting market. LED light source with high luminous efficiency, high color rendering coefficient, long life, energy efficient, ultra-low power consumption, and LED lights have more perfect dimming function, according to day and night traffic flow and other factors at any time to change the tunnel Lighting level, through the integrated WiFi, ZigBee and other network technologies, LED lighting for the tunnel lighting ushered in the era of intelligent lighting.
In 2007 the domestic LED road, tunnel lighting market began to form. In the first 5 years, due to many manufacturers ignored the issue of LED lighting cooling, LED road, lighting and other lighting projects led to the failure rate as high as 90%, misleading the LED lighting technology "is not mature enough to wait and see the development trend." public opinion. However, at the same time, ENELTEC developed 148 LED road and tunnel lighting projects with its own unique technology of heat dissipation and light distribution, and provided 250,000 high-power LED lamps all with stable operation. Among them, China's first LED tunnel lighting project - Jiangxi Jingying high-speed tunnel LED lighting project, the State Ministry of Transportation as energy-saving emission reduction demonstration project; the same project with ENELTECLED lamps - Fujian Nanhui Expressway tunnel was Development and Reform Commission, Ministry of Finance, Ministry of Transport as the highway tunnel LED lighting national demonstration project.
Tunnel lighting intelligent control system in addition to the lighting needs of different road sections, the use of a reasonable tunnel illumination illumination distribution, but also supports a variety of intelligent dimming methods, such as: as a tunnel lighting lamp, near the entrance and exit of the lamp Brightness should be closer to the normal outdoor light, decreasing gradually from both ends to the middle to reduce the "black hole, white hole effect" to enhance traffic safety; the same time, according to the time, season, weather, etc. automatically adjust the brightness to the appropriate location , Lighting system built-in different scene modes, intelligent management to ensure traffic safety. In this regard, ENELTEC Shaanxi Ossaw tunnel construction of intelligent lighting project, was named a national demonstration project.
In addition, ENELTEC's LED application products and intelligent control system are also applied to Yunnan Dali Highway Tunnel, Chongqing Zhangjiashan Tunnel, Hunan Liangshuijing Tunnel, Shanghai Dalian Tunnel, Beijing Jingcheng Expressway, Yunnan Puxuan Highway Tunnel, G85 Kunming Expressway Mazhao line tunnel and Hong Kong-Zhuhai-Macao Bridge deep sea tunnel built or under construction of large tunnel projects.
In recent years, with the acceleration of urbanization, people pay more and more attention to the safety and comfort of road traffic, and require more and more intelligent control technology for tunnel lighting. With the continuous development of new technology and new technology , Tunnel lighting intelligent control technology will also be "more energy-efficient, more comprehensive and more comfortable" direction.
