高速公路隧道LED灯具全寿命周期成本分析

Analysis of Life Cycle Cost of LED Lamps in Highway Tunnel

本文通过全寿命周期内LED灯具与传统高压钠灯在初始投资、养护费用、节电费用、残值等指标的全面对比,提出应用隧道LED灯具在大幅提高照明总体质量的同时可实现全寿命周期内的投资效益最大化。

Based on comparison of the whole life cycle cost analysis of LED lamps with traditional high pressure sodium in the initial investment, maintenance costs, saving cost, salvage and other indicators of overall contrast, this article proposes that the application of tunnel lighting LED lamps in the substantial increase in the overall quality of life, meanwhile, a maximize investment returns can be achieved.
