Abstract

We have seen an increasing number of reported colour maintenance issues in the market when it concerns LED-based products. Besides this, there are also requests to provide products that have < 2 SDCM colour point changes over lifetime. To understand the mechanisms behind colour maintenance in our LED-portfolio we have developed a calculation method that is able to predict colour maintenance as function of time, construction and material used. The details of that method are described in this paper.
