布灯方式对隧道照明的影响

为了研究布灯方式对隧道照明的影响，采用照明设计软件DIALux设计了隧道模型。在隧道模型里，分别按对称布灯方式、交错布灯方式和中央布灯方式建立了照明系统，使用相同的LED灯具，进行了仿真试验。试验结果表明，中央布灯方式的路面照度、亮度及亮度均匀度最高，照明效果最好，交错布灯方式优于对称布灯方式。在满足路面照度、亮度及路面亮度均匀度要求的前提下，中央布灯方式可以使用较小功率的灯具，从而节省电能。

INFLUENCE OF LUMINAIRE-DISTRIBUTION-STYLE ON TUNNEL LIGHTING

In order to research the influence of luminaire-distfibution-style （LDS） on tunnel lighting, a tunnel model was designed with lighting sofiware-DIAlux. A symmetrical LDS lighting system, a stagger LDS lighting system and a central LDS lighting system were established in the tunnel model, respectively. Three simulation tests of lighting were completed in the same tunnel model and with the same LED luminaires Furthermore, the tests results show that road-surface （RS） illumination, RS illuminance and RS illuminance uniformity of the central LDS lighting system are the highest, and its lighting effects is the best, the lighting effects of stagger LDS lighting system is better than that of symmetrical LDS lighting system. The central LDS lighting system can save energy by using less powerful luminaires in the required conditions of RS illumination, RS illuminance and RS illuminance uniformity.
