Research On Energy Saving Technology Of Highway Tunnel Lighting Based On Light Guidance System

With the rapid development of economic construction,China's highway construction,especially the rapid development of highway construction,has made rapid development.Highway tunnels are widely used in complex terrain,especially in mountainous areas.With the rapid development of highway tunnel construction,the scale and quantity of tunnel lighting facilities are also increasing,which inevitably leads to a substantial increase in the electricity consumption of tunnel lighting.In today's emphasis on sustainable development and energy efficiency,the energy consumption caused by tunnel lighting is in contradiction with the policy of green lighting and energy conservation.In order to solve some tunnel traffic phenomenon like the black hole effect during the day to enter the tunnel,lag behind reaction and the white hole effect,China and many countries have formulated a series of design principles and standards.Tunnel lighting whether the length of the tunnel,it's power consumption is mainly concentrated in the tunnel entrance.Although this section is only about 200 meters,but the concentration of power,high density of lighting layout,are not only the difficulties of the tunnel lighting,but also the focus of tunnel energy saving.Although the optical technology has been widely applied with other space to lighting,but tunnel lighting is different from the general place,it must consider the circadian lighting,tunnel region and the driver's visual adaptability.Therefore,the research on the optical technology can not only fill the gaps in the research of the light guide technology of the tunnel portal,but also make full use of the solar energy for the benefit of the tunnel energy-saving lighting.This paper makes full use of solar energy as a green energy,with the help of the light pipe technology into the tunnel portal section,to carry out the combination of solar and artificial lighting design of a hybrid lighting system.Through the investigation and study on the tunnel entrance which is facing a problem of energy saving,it can figure out that the energy saving scheme of optical lighting technology and artificial lighting,the key technology to solve the problems of solar system research and design ofautomatic tracking and intelligent light.Finally,the energy saving measures applied to the eventual establishment of optical tunnel entrance and artificial lighting,which provides a reference for the design and construction of similar projects.
