摘　　要：灯具的配光曲线和布灯方式影响着灯具利用系数,而灯具利用系数又影响灯具功率和路面照度,进而影响照明系统的功耗和路面照明效果。为此,文章建立了基于灯具配光曲线和布灯参数的隧道照明利用系数计算模型,选择了4种配光曲线,对每种配光曲线均采用中央布灯、拱顶侧偏布灯、对称布灯和交错布灯4种常用布灯方式进行优化和仿真,对隧道中间段的配光曲线和布灯方式的节能性和照明效果进行了研究。研究结果表明:对称布灯是最节能且照明效果最好的布灯方式;中央布灯方式的照明效果仅次于对称布灯方式;除了特殊形状的配光曲线,交错布灯方式功耗最大,照明效果最差;沿隧道横向的配光曲线是尖顶水滴状较好,适用于除交错以外的3种布灯方式;沿隧道纵向的配光曲线最好是对称蝶形分布曲线,适用于4种布灯方式;横向配光曲线是尖顶水滴状,纵向配光曲线是对称蝶形分布曲线时,适用于4种布灯方式,且都有较好的节能性和照明效果;对称倾斜式配光曲线,其倾斜配光剖面最好与隧道横向一致,适用于对称和拱顶侧偏两种布灯方式。Light distribution (LD)and installation style of luminaires affect the utilization factor (UF)of luminaires, and the UF affects the luminaire power and road pavement illuminance and further the power consumption of illuminating system and the luminous effect of road pavement.An UF model of tunnel lighting was established based on the luminaire LD data and installation parameters,in which four LD styles were adopted.For each LD the parameters optimization and simulation were conducted regarding four installation styles,e.g.central style,offset-of-vault style,symmetric style and staggered style.The energy-saving and the lighting effects of each LD and luminaire installation style at the tunnel middle zone were studied.The results show that symmetric luminaire installation is the most energy-saving style and has the best lighting effect than the other three luminaire installation styles;the lighting effect of central luminaire installation is the second best;staggered luminaire installation is the most energy-intensive style and has the worst lighting effect except for some special-shaped LD;waterdrop-shaped LD is the most suitable one along transverse direction of tunnel and applicable to the central,offset-of-vault and symmetric luminaire instal- lation styles;symmetric butterfly-shaped LD is the most suitable one along longitudinal direction of tunnel and applicable to the central,offset-of-vault,staggered and symmetric luminaire installation styles;with waterdrop-shaped LD along transverse direction and symmetric butterfly-shaped LD along longitudinal direction,they are suitable for the above four luminaire installation styles,and have better energy-saving and lighting effect;as for the LD with symmetric and oblique curve,it's better for the profile of oblique luminaire distribution to be comply with that along tunnel transverse direction,and it is suitable for the symmetric and offset-of-vault luminaire installation styles.
