摘要
FIELD: luminescent lamps. SUBSTANCE: the luminescent composition comprises (wt): 23-92 strontium and magnesium orthophosphate activated with tin; 22-34 strontium halophosphate activated with antimony; 3-20 potassium halophosphate activated with antimony and magnesium having a color temperature of 3600-6500 K; 27- 44 barium titanate-phosphate. The composition is prepared by mixing components in a ball mill. The properties of 18 W lamps with a composition comprising said components in an amount of 28, 29.4 and 35 wt the light flux after 100 hours of combustion is 885 lm; the color intensity coordinated: x is 0.320 and y is 0.341. The composition assures distribution of the radiation flux in the spectrum zones. EFFECT: improved properties of the luminescent composition. 1 dwg, 1 tbl
