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.
