Abstract
Light bulb having more glow filaments and possibility of their independent switching on has a novelty in that it comprises the glow filaments (A) that permanently in the current circuit when the electric bulb is in use, and in case of fusing thereof, or need for the increase of electric power of the light bulb, a small metal screw (5) is fixed and electric contact between the metal coating (3) and a terminal (4) of glow filament (B) are achieved. Thus, it switches the current circuit on, i.e. activates it. Electric bulb like this may involve even more than two glow filaments in mutually independent electric circuits and thereby to multiply duration of the electric bulb, and without any corrections onto the existing electroinstallations it is applicable in all cases where the standard electric bulb is used with the glow filament.
