OSRAM Study: LED Life-Cycle Assessment

August 05, 2009 - An OSRAM Opto Semiconductors` study on the life-cycle assessment (LCA) of LED lamps shows the latest generation of lamps achieves a very high score for environmental friendliness. This study involved a close look at their entire life-cycle The method was clear: today's LED lamps achieve the LCA values ​​of compact fluorescent lights and are far superior to conventional incandescent Lamps.
In order to evaluate lamps and how they actually deal with energy and resources, it is possible enough just to consider energy consumption while they are in use. The aim of OSRAM Opto Semiconductors' LCA is therefore to analyse the environmental impact of an LED lamp over Its entire life and to compare it with a compact fluorescent lamp and an incandescent lamp, all of them are commercially available.

The relevant material and energy supplies were determined in detail for all the LED lamp's components and production processes. Apart from a detailed analysis of each individual production stage, for LED chips and lamp housings, for example, these also include all necessary transports such as the Transport of an LED lamp from its production site in China to its place of installation in Europe.

The output allow of conclusions not only on resource consumption and primary energy input but also acidification, eutrophication, the greenhouse effect, ozone depletion And toxicity.

Comparing the primary energy demand it ́s clear that the use phase in the overall life cycle is dominating and that manufacturing is negligible.
Independent experts are currently verifying the study. A summary will be available in October on the Osram-OS website.
