LIGHTING FITTING Russian patent published in 1994 - IPC

FIELD: lighting engineering. SUBSTANCE: capacitor 3 arranged in bulb 1 accumulates electric charge when current is supplied to capacitor along electrodes 2. With current supply turned off, electric charge on capacitor plates 4 is preserved. Capacitor plates are covered with layer of fluorescent material. Electric field is formed on plates and under action of electric field fluorescent material emits radiant flux. EFFECT: enlarged operating capabilities. 2 cl, 2 dwg
