POLYMER LUMINESCENT COMPOSITE FOR COLOURLESS LIGHT PRODUCTION, WHICH IS EXCITED BY BLUE LIGHT-EMITTING DIODE Russian patent published in 2015 - IPC C09K11/78 C09K11/80 C08L69/00 

Abstract RU 2549406 C1

FIELD: electricity.

SUBSTANCE: invention is referred to light engineering, in particular to polymer luminescent composites used for arrangement of general and local lighting. The polymer luminescent composite excited by blue light-emitting diode contains transparent polycarbonate with melt flow index of 6-40 g/10 min, photoluminiscent phosphor - yttrium- gadolinium alumogallic garnet activated by cerium with formula of (YGd)3(AlGa)5O12:Ce, powdered polyethylene wax with particle size of 18-30 mcm, heat stabiliser - Ultranox 626 and Tinuvin 360.

EFFECT: suggested composite provides reduced intensity of blue light and increased illumination.
