LED 路灯节能改造工程的实测与分析

摘要

Yubei district of Chongqing reconstructed the part of primary and secondary roads ’ High voltage sodium lamps by the way of LED energy-saving within the scope of jurisdiction .The quality of road lighting and the energy saving effect after reconstruction should be appraised by practice .The site’s illuminance, brightness, the actual electricity saving rate before and after the replacement of road lamp have been measured and analyzed , obtaining the actual use effect of LED and High voltage sodium lamp by contrast .Research shows that the quality of road lighting is improved, the illuminance, brightness and evenness degree is increased and the actual energy saving rate is increased to 50%by means of energy-saving renovation via LED road lamp .%重庆市渝北区对辖区范围内的部分主、次干道高压钠灯进行了LED节能改造。本文针对道路现场灯具更换前后的照度、亮度、实际节电率等进行了测量和分析，对比研究得出了LED与高压钠灯的实际使用效果。研究表明，经LED路灯节能改造后，道路照明情况改善，照度、亮度及均匀度提高，实际节电率达50％以上。
