Claim 14:
15. A method for manufacturing a luminescent component according to claim 1, comprising the steps of:
—Method A—
providing a substrate which is optionally coated with one or more layers;
applying to said substrate a first liquid polymer composition comprising monomers or oligomers of the first polymer P1, first luminescent crystals, optionally solvent, optionally further materials, optionally third luminescent crystals;
optionally heating said liquid first polymer composition at elevated temperature to remove volatile solvents;
curing said first liquid polymer composition to obtain the first element;
applying to the thus obtained hardened surface of said first element a second liquid polymer composition comprising monomers or oligomers of the second polymer P2, optionally second luminescent crystals, optionally solvent, optionally further materials;
optionally heating said liquid second polymer composition at elevated temperature to remove volatile solvents;
curing said liquid second polymer composition to obtain the second element, which covers and thereby seals said first element;
optionally applying further coating or finishing steps; OR

—Method B—
providing a substrate which is optionally coated with one or more layers;
applying to said substrate a second liquid polymer composition as defined above;
optionally heating said liquid second polymer composition at elevated temperature to remove volatile solvents;
curing said second polymer composition to obtain the second element;
applying to the thus obtained hardened surface of said second element a first liquid polymer composition as defined above;
optionally heating said liquid first polymer composition at elevated temperature to remove volatile solvents;
curing said liquid first polymer composition to obtain the first element, which is covered and thereby sealed by said second element on its lower surface;
applying further coating or finishing steps; OR

—Method C—
providing two substrates each coated with a layer of the second element
laminating a layer of first elements with these coated substrates; OR

—Method D—
providing a first liquid polymer composition comprising monomers or oligomers of the first polymer P1, first luminescent crystals, optionally solvent, optionally further materials, optionally third luminescent crystals;
one of
a) extracting multiple first elements from the first liquid polymer composition by one of spray-drying, or precipitation, or
b) hardening the first liquid polymer composition into the first solid polymer composition, and crushing the first solid polymer composition resulting in multiple first elements,

mixing the first elements into a second liquid polymer composition as defined above, and
providing a substrate which is optionally coated with one or more layers;
applying to said substrate said second liquid polymer composition containing the first elements;
optionally heating said liquid second polymer composition at elevated temperature to remove volatile solvents;
curing said liquid second polymer composition to obtain the second element, which covers and thereby seals said first elements; and
optionally applying further coating or finishing steps.
