In order to create a safe and comfortable tunnel lighting environment and provide a good driving experience for the driver, this paper analyzes the influence of the layout of the luminaires in the tunnel on the glare of the luminaires. By establishing a tunnel simulation model, the threshold incremental glare evaluation method is used to explore the relationship between the spacing and height of the luminaire and the glare level under different vehicle types. The research results show that increasing the height of the luminaire can effectively reduce the glare effect, and the glare difference of different models becomes smaller; increasing the spacing of the luminaires will slightly increase the glare, and the glare difference of different models is almost unchanged. Therefore, when the tunnel is illuminated, the height of the layout can be increased, and the spacing of the luminaires can be increased within a certain range to achieve safety and energy saving effects. The research results have reference significance for the setting of highway tunnel lighting fixtures.
