Study on the Highway Tunnel Lighting with Spectrum Superposition

Abstract:

The lighting level of highway tunnel is usually under mesopic vision condition, but the traditional luminance and illuminance test are corrected by photopic vision spectral luminous efficiency. According to the difference of spectral luminous efficiency between photopic and mesopic, the lighting with different peak wavelength would provide various ratios of radiation / photometric flux. Four kinds of narrowband light sources with the same tested flux were stacked up in white LED and HPS respectively, through equivalent brightness calculation, the most efficient spectral wavelength were obtained under mesopic condition.
