商场常用光源能耗及全寿命周期环境影响研究

Life Cycle Analyses of Three Typical Lamps and Their Lighting Power Density1

建立了两个典型专卖店一般照明模型,在满足同等照明数量及质量要求的条件下,对使用八种常用卤钨灯、节能灯及小功率陶瓷金卤灯灯具的照明方案进行了功率密度比较;并采用能源服务研究模式,对相应光源在全寿命周期内所产生的汞污染、温室气体数量进行了对比研究;对推广小功率陶瓷金卤灯所遇到的问题进行了探讨。

This article describes several general lighting models in two typical retail shops. It compares the lighting power density （LPD） of eight different designs that use halogen, compact fluorescent and low-wattage ceramic metal halide lamps. An analysis of the environmental impacts such as mercury and Greenhouse Gas （GHG） emissions of these lamps is undertaken in regards to their life-cycle by using the energy service formula. The article also discusses the technical and economic problems when low-wattage ceramic metal halide lamps are used in commercial applications and provide appropriate recommendations.
