基于连廊的隧道照明节能研究

Energy Saving of Tunnel Lighting Based on Corridor

通过建立自然光光照模型,得出自然光情况下光线的分布情况,在此基础上,将隧道入口段的加强照明换成连廊下的自然光照明,通过分析在连廊情况下的光照情况,建立连廊下隧道入口段的光照模型。以潮惠高速公路银山隧道段的设计模型为例,对入口段采用连廊自然光照明的模型进行验证。研究表明:将隧道入口段的加强照明换成连廊下的自然光照明,可以很好的满足隧道入口前半段的照明需求。相比加强照明,大大降低了隧道入口处的照明耗电量,在同等条件下,入口段采用连廊自然光的照明方式较传统照明方式,降低隧道能耗比达16.69%。

By establishing a model of natural light illumination,the light distribution model under the natural light condition was obtained.On basis of this,the enhanced lighting at the entrance section of the tunnel was replaced by the natural lighting under the corridor.And the illumination model of tunnel entrance under corridor was established by analyzing the illumination of corridor.Taking the design model of Yinshan Tunnel section of Chao-Hui Expressway as an example,the model of corridor natural light illumination at the entrance section was verified.The research shows that the lighting requirement of the first half of the tunnel entrance can be well met by replacing the enhanced lighting of the tunnel entrance with the natural lighting under the corridor,which greatly reduces the lighting power consumption at the entrance of tunnel,compared with the enhanced lighting.Under the same conditions,the energy consumption ratio of the mode of corridor natural light illumination at the entrance section is 16.69%lower than that of traditional lighting.
