FIELD: electricity.SUBSTANCE: inventions may be used in lighting systems. A luminophor mixture consists of rare-earth red-emitting phosphor, for example YOE, rare-earth green-emitting phosphor, for example any of LAP, CAT or CBT, and rare-earth blue-emitting phosphor, for example any of BAM and SCAp. The size of 50% of phosphor, i.e. the medium diameter in volume, varies from 12 mcm up to less than 15 mcm. A fluorescent lamp contains electrodes and a glass encapsulation coated with the above mixture at the inner side, sealed hermetically and containing mercury and an inert gas. The luminophor coating is applied in one or two layers, the first layer is up to 40-60% of the weight of the luminophor coating.EFFECT: inventions ensure an increased efficiency of the fluorescent lamp.14 cl, 7 dwg, 1 tbl |
