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.
