By the end of 2015, Chinese total mileage will reach 4.5 million kilometers. Among them, the tunnel construction will reach new heights. By the end of 2010, China has built more than 450 seats highway tunnel, length of over 120 kilometers. In the wave of this wave in tunnel construction, LED lighting systems and energy security both for its excellent performance will occupy the leading position.
Tunnel lighting, as well as its 24-hour continuous operation with particular emphasis on safety features, has strong demand for new energy-efficient lighting systems. With the continuous development of tunnel lighting technology, in recent years it appeared to LED, warm white and discharge lamp as the representatives of a variety of new lighting technologies , alternative to traditional high pressure sodium lamps and fluorescent lamps. Among them, LED favored. As energy saving, long life, easy maintenance and light system, using LED’s not only enhance the safety level, but also can effectively reduce energy consumption and operating costs tunnels. Data show that in 2010 China had only 100,000 LED tunnel lights used in tunnel construction. It is believed to have made good social and economic effects. LED lighting used in the tunnel is a comprehensive project, not only to consider the energy-saving effect , brightness , uniformity, but also driver’s visual experience are required in areas such as integrated into consideration. Thus, LED tunnel lighting needs to have a forward-looking concept of planning and guidance, in order to achieve energy-saving lighting and improve the quality of synchronization.
First, to achieve sufficient surface brightness should be a prerequisite to achieve energy efficiency. Sided intermediate visual theory to emphasize the white road lighting applications in a relatively traditional sodium yellow light, energy efficient, thereby reducing the illumination LED lighting applications, security might lay hidden.
Second, it should be related to the use of indicators related to the brightness of the tunnel lighting standards to measure LED tunnel lighting effects to achieve average brightness and brightness uniformity harmony for optical design.
ENELTEC LED tunnel lights will effectively change the LED lamps with short projection based on tunnel lighting applications present situation, in order to effectively improve the amount of light a single light and power use per unit length to reduce the number of lamps to help owners reduce initial costs, overall and long-term energy savings.
