 Tunnel light pipe daylighting systems are introduced: 
 The light pipe lighting technology used in the tunnel or basement corridor in a foreign country has a lot of success stories. The light pipe daylighting systems are basically installed vertically, the vertical direction of the light guide tube through the complex structure of the ground, the natural light into an underground. In order to transport the larger luminous flux, light pipe diameter is generally greater. From the lighting point of view, a tunnel is divided into four areas: the entrance area, the transition region, the tunnel area and exit area. People close to during the day from a bright environment, entry into and through the tunnel process is very different from driving on an ordinary road, because this process will be a visual problem. First of all, the key to the design of the entrance area to eliminate the black hole phenomenon, at the entrance road to reach the necessary level of brightness, so the entrance must be set to the light pipe system. Secondly, the brightness level of the transition zone should gradually reduce, you can select small-caliber light pipe system. Again, the visibility of the tunnel area is lower than the average road luminance level recommended for the 5-20cd / m ^ 2 under the conditions of this low level, it is not possible to use a continuous band of light, so to prevent interference in the use of strobe, electric light source can not avoid the presence of strobe light pipe system in the tunnel area application suitability. Finally, exports to this area is likely to cause a strong effect of the glare, the use of electric light can only strengthen this glare effect, therefore, this region using the light pipe system is also very appropriate. In addition, the tunnel Can I use light pipe lighting depends on the tunnel above, what if the tunnel is then over mountains, it is very difficult to install guide fluorescent tubes lighting. In any case, the tunnel using the light pipe daylighting is a lot of practicality and adaptability. 
 Beijing Oriental scenery of New Energy Technology Co., Ltd. is the earliest R & D and production guide is a professional manufacturer of fluorescent tubes and lighting systems, and the Oriental scenery (Eastview) series of products have reached the international level; in the Olympic Forest Park, Samsung 2008 Olympic Exhibition Center, Tsinghua University University of energy-efficient demonstration building, the Embassy of the Netherlands, Red Oriental International Garden, Qinhuangdao in the water party eco-energy communities, Shandong starfish Group's new plant nearly ten projects are widely used.
