Abstract: Based on the theory of Life Cycle Assessment and SimaPro software(Version8.0), the Eco-indicator 99 method was used to analyze the life cycle impact of a closed-loop LED lamp supply chain and the results were compared with an open-loop LED lamp supply chain which has the same function unit. Results indicated that the environmental single score of a 21 W LED lamp in the entire process of the closed-loop supply chain was 5.48 Pt. The descending order of the three categories of environmental impact was: human health(3.81 Pt)> resources consumption(1.29 Pt)> ecological environment(0.381 Pt), indicating that the whole process of the closed-loop LED lamp supply chain had the most significant impact on human health. In addition, the environmental single score of the open-loop LED lamp supply chain with the same function unit was 5.71 Pt, increasing by 0.23 Pt compared with the closed-loop supply chain, which indicated that the closed-loop LED lamp supply chain was much more environmental friendly than the open-loop LED lamp supply chain.
