Abstract

The invention discloses a double-filament bulb, relates to the illumination appliance field, and specifically relates to a bulb; a conventional bulb has only one filament, once the filament is burned, the bulb cannot serve any longer, so the bulb is limited in life; the double-filament bulb aims to solve said problems, and mainly comprises a bulb body, filaments 1 and 2 arranged in the bulb body, and a live-zero contact pair 1 and a live-zero contact pair 2 arranged in the bulb body tail; the bulb body belongs to a hollow sphere filled with an inert gas; the filament 1 pole is about 20mm, and the filament 1 length is about 30mm; the filament 2 pole is lower and about 15mm, and the filament 2 length is shorter and about 25mm; the filaments 1 and 2 are arranged to form a cross type. The double-filament bulb can prolong the service life.
