隧道拱墙装饰方案对照明效果的影响研究

Study on Influence on Lighting Effect Caused by Decoration Schemes

为了定量分析隧道侧墙和拱顶的装饰方案对照明效果的影响,文章采用能够考虑侧墙和拱顶的二次反射光的DIALux软件,分析了相同的灯具配置、不同的隧道装饰方案时隧道路面的亮度情况。结果表明:隧道装饰方案对照明质量的影响是存在的。建议在通风条件良好的短隧道中,应积极推荐采用拱顶为浅灰色,侧墙为纯白色的装饰方案;在隧道进洞口,甚至建议拱顶也采用白色,进一步提高洞口入口段的亮度,缓解黑洞效应。

In order to quantitatively analyze the influence on the lighting effect caused by different decorative schemes of the side wall and the vault in tunnels,the DIALux software,which can consider the reflection lights,is adopted to illustrate the brightness situation of the tunnel pavement with same luminaire configuration and different tunnel decoration schemes.The result proves the tunnel decoration scheme has certain effects on tunnel lighting.The decoration scheme with light grey vault and pure white side wall is recommended for short tunnel with good ventilation condition.As for the tunnel entrance,even a white vault is recommended to improve the brightness of the entrance section of the tunnel in order to lessen the black hole effect.
