FIELD: lighting.
SUBSTANCE: invention relates to a lighting device including a light source for generating light source radiation and a light converter. The converter includes a matrix of the first polymer. The matrix includes discrete zones that contain the second polymer with luminescent functionality, representing a polyarylene ester containing luminescent fragments. The first polymer is chemically different from the polyarylene ester. The discrete zones occupy a volume in the range of 0.5-50% of the volume of the converter. A converter for converting light into luminescence and a method for obtaining said converter are also described.
EFFECT: increase in the stability of luminophore and increase in the life of the converter.
