隧道照明的节能配光设计与实现

Light Distribution Design and Realization of Tunnel Lighting with Energy Saving

隧道照明的首要目的是满足使用者的视觉需求,在此前提下还应尽可能地实现节能环保。为达到此目标,提出了根据具体隧道区段、灯具安装条件以及驾驶员视觉光环境需求来逆向设计灯具光分布以实现系统节能的思路,首先通过建立相应的最优化模型,得到特定条件下灯具应具有的光分布特性,再利用自由曲面光学设计方法,获得光分布的透镜曲面,最后,分别利用本设计的灯具和市面上现有的LED隧道灯进行仿真计算比较,结果表明,该方法设计的LED隧道灯能显著改善隧道内驾驶员视觉光环境质量,且节能12%以上。

The primary purpose of tunnel lighting is to meet the user's visual needs, in this context it should be possible to achieve energy saving. In order to achieve this goal, this paper proposed ideas of achieving energy-saving of according to the specific section of the tunnel, lighting installation conditions and environmental needs of the driver's visual light to reverse design of lamp light distribution system. Firstly, we can obtain light distribution characteristics of the lamp under certain conditions by establishing the appropriate optimization model. And then we can obtain the lens surface to achieve this light distribution by using free-form surface optical design method. Finally, the use of this design were available in the market LED lamps and tunnel lamps comparing simulation results show that the designed LED tunnel lights inside the tunnel can significantly improve the environmental quality of the driver's visual light, and can achieve more than 12%energy saving lamps.
