Abstract
En 中文
With the proliferation of tunnels in mountainous and intricate landscapes, the design of tunnel lighting has emerged as a crucial factor in curbing tunnel-related accidents and bolstering driving safety. This study employed scaled experiments and integrated human eye luminance adaptation curves to refine tunnel lighting configurations. The investigation revealed that the incorporation of high-light-transmittance sunshades within tunnels effectively diminished external luminance, thereby the alleviating the 'black hole effect '. From an economic perspective, adopting a tunnel lighting model with sunshades can achieve up to a 30% reduction in annual electricity costs. This study presents innovative strategies and methodologies for optimizing tunnel lighting design, offering valuable insights for future tunnel construction and lighting design endeavours.
