The drivers who walked on the Beijing-Chengde Expressway recently discovered that the dimly lit lights of the Simatai Tunnel had become brighter, and the dazzling bright lights bid farewell to the darkness and loneliness of the past. Looking up, I found out that the original tunnel lights have all been replaced with new ones. What kind of tunnel lights have such good effects? That's right, this is the bright and energy-saving LED tunnel light. The tunnel lights of the traditional light source have all been replaced by the bright LED tunnel lights. The Simatai Tunnel has become the first highway tunnel in China that uses LED tunnel lights.
LED is a new type of semiconductor lighting technology. Compared with traditional lighting technology, LED has superior energy-saving and environmental protection advantages, and is known as "the three inventions of human electronic products in the 20th century." All countries in the world are very optimistic about the prospects of LED, and formulate various LED promotion plans. The 11th Five-Year Plan also listed it as a priority development project in the energy sector. As one of China's national semiconductor lighting industrialization bases, Hebei is very aware of the advantages and functions of LEDs. It has been actively promoting LED application products in government projects to replace the old and traditional lamps.
Hebei Chengde Simatai Tunnel is located in the important section of the Beijing-Chengde Expressway and is the gateway to Beijing and its surrounding areas. The traffic in the tunnel is endless, and there are countless. However, the light from the traditional light source used in the tunnel is dim and dark, which is quite different from the natural light outside the tunnel. Drivers take time to adapt each time. At the same time, traditional tunnel lights consume a lot of power and consume a lot of power resources every year. In view of this, Hebei Province began to use the bright green energy-saving LED tunnel lights here. After more than one month of testing, it has been completed and accepted, and the true LED tunnel lights are officially “on the jobâ€. The Simatai Tunnel became the first highway tunnel in China to use LED tunnel lights.
The new "on duty" is the true 75W LED tunnel light SD-60-RY. The luminaire adopts high-power LED as the light source, adopts a unique optical design, and installs a reflector on each LED, so that the light distribution of the whole lamp is designed as a batwing shape, and the light distribution is properly controlled to ensure the ideal illumination brightness and The uniformity also eliminates the glare of the LED. It has many advantages such as good color rendering, long service life, high efficiency and energy saving, low maintenance cost, stable light efficiency and wide operating voltage range.
Since its launch, the bright LED tunnel lights have been widely used in the lighting of highway tunnels, municipal road tunnels, cross-street tunnels, railway tunnels and other places. The products installed in the Simatai tunnel have performed well and have received wide acclaim.
