城市照明系统多因素节能技术研究

摘要

It is a completely urgent question that saving energy with ensuring urban functional lighting and keeping beautiful urban night scene.This article researches saving energy looking urban lighting upon as a multifactorial synthetic system.Then this article analyses the composition of urban lighting system and summarizes the current researching situation about illuminative energy conservation at home and abroad.Meanwhile,this article puts forward three key techniques about saving energy including road and tunnel illumination,defining brightness value of different urban areas and illumination design on the basis of light reflecting characteristics of materials.This article provides a new research way for saving energy about urban illumination.%在保障城市功能照明和保持城市夜景美感的前提下节约能源,是一个亟待解决的问题。将城市照明作为一个多因素的综合系统进行节能研究,文章分析了城市照明系统的组成部分,总结了国内外照明节能的研究现状,提出了道路照明与隧道出入口段的照明节能、城市区域亮度值的确定以及根据建筑物饰面材料的光反射特性进行照明设计节能的三个关键技术,为实现城市照明节能提供了新的研究途径。
