隧道侧壁内装材料的照明节能

Lighting Energy Saving of Tunnel Sidewall Interior Materials

以照明设计软件DIAlux模拟隧道照明真实环境,利用其具有双向反射分布函数与光线跟踪算法的独特功能进行了侧壁直接反射光与间接反射光的计算,通过计算结果分析了隧道侧壁内装材料的反射系数与隧道灯具的不同组合对隧道路面照明质量的影响规律。研究结果表明,从安全角度考虑,隧道侧壁上采用具有较高的反射系数的内装材料能增加隧道内照度、亮度以及均匀度,从而提高隧道的照明质量使行车更加舒适;从节能角度考虑,在设计之初考虑利用较高反射系数的隧道侧壁内装材料的节能作用可适当减少隧道灯具的功率,对隧道的节能具有现实意义。

We used lighting design software DIAlux to simulate the real environment of tunnel lighting, and used its unique function of two-way reflection distribution function and light tracking algorithm to calculate the direct reflected light and indirect reflected light reflected by sidewall. Then, based on the calculation result, we analyzed the influence regularity of the reflection coefficient of the tunnel sidewall interior materials and different combinations of tunnel lighting on lighting quality of pavement in tunnel. The research result shows that （1） from security perspective, the tunnel sidewall that using interior decoration material with high reflection coefficient can increase illumination, luminance and uniformity inside tunnel to increase the tunnel lighting quality and make travel more comfortable; （2） from energy saving perspective, considering the energy saving effect of using interior decoration material with high reflection coefficient at the beginning of design can properly reduce the power of the tunnel lamps, which has realistic significance to tunnel energy saving.
