Research on Energy Saving in Highway Tunnel Lighting

On the basis of driving safety and visual comfort, highway tunnel lighting also needs to achieve the purpose of saving energy. This paper provides a literature review on the current situation and development background of the research related to energy saving in tunnel lighting by combining three aspects: tunnel lighting design methods, tunnel lighting specifications and standards, and tunnel lighting related technologies, and discusses the relationship between tunnel lighting design methods, tunnel lighting specifications, tunnel lighting related technologies and energy saving in tunnel lighting, as well as design methods and design parameters suitable for highway tunnel lighting. Based on this, through a two-way analysis combining technology and actual cases, strategies to achieve energy saving in tunnel lighting such as photovoltaic power supply technology, solar fiber optic lighting technology, new energy-saving light source and intelligent lighting control system are proposed to provide a more in-depth and specific perspective on the practice of energy saving in highway tunnel lighting.
