Abstract

A stack of layers, a lamp, a luminaire and a method of manufacturing a stack of layers is disclosed. The stack of layerscomprises a first outer layer, a second outer layerand a luminescent layer. The first outer layerand the second outer layerare of a light transmitting polymeric material and have an oxygen transmission rate lower than 30 cm3/(m2-day) measured under standard temperature and pressure (STP). The luminescent layeris sandwiched between the first outer layerand the second outer layerand comprises a light transmitting matrix polymer and a luminescent materialbeing configured to absorb light according to an absorption spectrum and convert a portion of the absorbed light towards light of a light emission spectrum.
