METHOD FOR CONNECTING INCANDESCENT LIGHTING LAMP INTO ELECTRIC CIRCUIT Russian patent published in 1995 - IPC

Abstract RU 2050652 C1

FIELD: electrical engineering. SUBSTANCE: method involves adjustment of filament circuit resistance in transient condition by serial connection of series resistance functioning as semiconductor with negative temperature coefficient of resistance so that each moment when transisent condition exists, R_н+R ≥ R*н

+R^*, relation is satisfied, where R_н is current value of lamp filament resistance; R is current value of series resistance with negative temperature coefficient of resistance; R*н

is filament resistance by end of transient condition; R^* is value of series resistance with negative temperature coefficient of resistance by end of transient condition. EFFECT: facilitated procedure. 4 dwg
