1. A luminescent component, comprising a first element and a second element, wherein:
said first element comprises a first solid polymer composition, said first polymer composition comprising first luminescent crystals embedded in a first polymer (P1), wherein
said first luminescent crystals are of the perovskite crystal structure and emit light of a first wavelength in response to excitation by light with a wavelength shorter than the first wavelength,
said first polymer (P1) is selected from the group consisting of crosslinked polymers and polymers with Tg<95° C.;
said second element comprises a second solid polymer composition, said second polymer composition optionally comprising second luminescent crystals embedded in a second polymer (P2), wherein
said optional second luminescent crystals are different from said first luminescent crystals and emit light of a second wavelength in response to excitation by light with a wavelength shorter than the second wavelength,
said second polymer (P2) is selected from the group of crosslinked polymers; and wherein
said second element at least partially covers and thereby seals said first element; and
said Tg is measured according to DIN EN ISO 11357-2: 2014-07 during the second heating cycle and applying a heating rate of 20K/min, starting at −90° C. up to 250° C.
