Lumileds: Evaluating the Lifetime Behavior of LED Systems

December 13, 2016 // By Lumileds
Using lumen maintenance data that describes how a single LED behaves can create unplanned business risks and potentially affect end-customer experiences with LED solutions. An array of LEDs behaves differently than a single LED and it is possible to account for the extremely slim chance that a quality power LED will fail completely. Luminaire manufacturers are also learning how to better account for the lifetime behavior of the many other components that are used including drivers, optics, mechanical fixings and housings. Each of these is also a factor in determining the lifetime of a luminaire. Fortunately, responsible LED luminaire manufacturers are beginning to incorporate more detailed analysis and utilize the methods and tools that are covered in this paper so that they can more accurately project and report lifetime behavior.
