(TU Delft Materials Innovation Institute) van Driel, W.D. (TU Delft Electronic Components, Technology and Materials) Zhang, Kouchi (TU Delft Electronic Components, Technology and Materials) Department Materials Innovation Institute Date 2015 Abstract In this paper, progresses of color maintenance, also known as color shift, in solid-state lighting (SSL) systems are thoroughly reviewed. First, color shift is introduced and a few examples are given from different real-life industrial conditions. Different degradation mechanisms in different parts of the system are also explained. Different materials used as lenses/encapsulants in light-emitting diode (LED)-based products are introduced and their contributions to color shift are discussed. Efforts put into standardization, characterizing, and predicting lumen maintenance are also briefly reviewed in this paper.
