生命周期评价（LCA）作为一种重要的环境管理工具，不仅能够对材料或产品全生命周期所涉及的环境问题进行评价，而且能为可持续发展决策提供依据，有利于促进产品、行业甚至整个产业链的行为更符合可持续发展的原则。但是目前国内还尚未有关于LED照明产品的生命周期评价。本文综述了生命周期评价方法在LED照明领域的应用，并提出我们的新思路，即将产品设计要素、经济成本要素及环境影响相结合的LED照明产品全生命周期评价方法。,As an effective environment management tool, life cycle assessment (LCA) not only gives a detailed information of environmental proifles of a material or a product, more importantly, the value of LCA lies in life cycle thinking having the access to offer decision-making basis for sustainable development, making the products, industry and even the whole industry chain act in line with the principles of sustainable development. However, there is no research for LED lighting product LCA in China. This article summarizes the application of LCA method in LED lighting ifeld, and suggests a thinking route-the LCA method of LED lighting product combing product design factors, economic cost factors and environment inlfuence.
