节能灯、白炽灯和卤钨灯全生命周期评估对比

Comparison of the Life Cycle Assessment of Compact Fluorescent,Incandescent and Tungsten Halogen Lamps

采用全生命周期分析(LCA)的评估研究方法,全面、科学地对比分析了节能灯、白炽灯以及卤钨灯全生命周期过程中所造成的环境、资源影响,评估结果表明节能灯相对于白炽灯和卤钨灯显著降低了对环境的生态毒性影响,由于照明产品自身环境影响的特点,节能灯其突出的节电效果将显著降低白炽灯和卤钨灯对环境的各种影响。

In this paper, the influences of compact fluorescent, incandescent and tungsten halogen lamps during their whole life cycles on the environment and resources are analyzed in a comprehensive and scientific way by use of the evaluation method of life cycle assessment. The results indicate that CFLs（compact fluorescent lamps） significantly reduce the environmental impact of eco-toxicity, and because the lighting products have their own characteristics of environment influences, the outstanding feature of electricity saving of CFLs significantly reduces all the environmental impacts to be caused by incandescent and tungsten halogen lamps.
