SUBSTANCE: lighting fixture has incandescent lamp with hardware and dome open on top and at bottom; it also has two electrodes upper one being made in the form of set of plates and lower electrode is gauze of transparent electricity conducting material. Electrodes are supplied with voltage so that one pole is placed at positive potential and other pole, at negative potential. Voltage source is thermal converter or rectifier connected to supply mains. Electric lamp emits light and heats up surrounding atmosphere so that air moves inside dome from bottom upwards. Dust particles accumulated on lower electrode are electrolyzed and on upper electrode they are attracted and settle down. EFFECT: provision for not only illuminating premises but also for cleaning atmosphere inside them. 4 cl, 1 dwg øøø1
