POLYMER LUMINESCENT COMPOSITION FOR OBTAINING WHITE LIGHT EXCITED BY BLUE LIGHT-EMTTING DIODE Russian patent published in 2010 - IPC C09K11/78 C09K11/80 C09K11/02 C08K3/18 

FIELD: chemistry.

SUBSTANCE: polymer luminescent composition for obtaining white light excited by a blue light-emitting diode contains the following components, pts. wt: transparent polymer 100; photoluminescent phosphor based on garnet Y₃Al₅O₁₂:Ce or Gd₃Al₅O₁₂:Ce, or based on a mixture of said compounds 1.5-5.0; polyethylene wax in form of powder with particle size of 18-30 mcm 0.1-0.7; stabiliser 0.2-1.0. The transparent polymer used can be polycarbonate, polystyrene or a copolymer of styrene with acrylonitrile and butadiene. The stabiliser can be a compound from a group of sterically hindered phosphites.

EFFECT: Invention enables to obtain a protective lighting composition which provides low colour temperature, improved colour coordinates.
