环保型城市生态景观照明节能数字化辅助设计

针对环保型城市生态景观照明时平均照度不高、耗电量过大等问题，提出环保型城市生态景观照明节能数字化辅助设计。根据国家规定照明标准，构建环保型城市生态景观照度参照值以及城市住宅防控干扰光强度限制值，并依据规定单位面积照明功率密度值，设定单位面积安装功率限制；依据以上设定标准，通过数字化辅助设计城市生态景观照明原则以及灯具选取指标，构建景观照明节能数字化控制指标体系，结合照明节能评估与改进意见，实现生态景观照明节能数字化控制。分析结果显示:中央布灯方式的路面平均照度与路面总均匀度更高，节能效果高于对称与交错布置；白天场景节能效果高于夜间场景，最高节能占比达到60%；布灯间距为50 cm、灯具角度为0°时，平均照度最高，节能效果最佳。

Energy-saving digital assisted design of ecological landscape lighting in environmental protection urban

Aiming at the problems of low average illuminance and excessive power consumption in environmentally friendly urban ecological landscape lighting，an environmentally friendly urban ecological landscape lighting energy-saving digital auxiliary design is proposed.According to the national lighting standards，the environmental protection urban ecological landscape illuminance reference value and the urban residential interference prevention and control light intensity limit value are established，and the unit area installation power limit is set according to the specified unit area lighting power density value；according to the above setting standards.Through the digital aided design of urban ecological landscape lighting principles and lamp selection indicators，a digital control index system for energy-saving landscape lighting is constructed，combined with lighting energy-saving evaluation and improvement opinions，to achieve digital control of ecological landscape lighting energy-saving.The analysis results show that the average illuminance of the road surface and the total uniformity of the road surface of the central lighting method are higher，and the energy-saving effect is higher than that of symmetrical and staggered arrangements；the energy-saving effect of daytime scenes is higher than that of nighttime scenes，with the highest energy saving ratio reaching 60%；when the lamp angle is 50 cm and the lamp angle is 0°，the average illuminance is the highest，and the energy-saving effect is the best.
