The invention provides a filament lighting increasing device. The filament lighting increasing device comprises a first synchronous increasing part, a second synchronous increasing part, a first probe, a second probe, a first filament carrying part and a second filament carrying part, wherein the first synchronous increasing part is vertically arranged; the second synchronous increasing part is parallel to the first synchronous increasing part and is vertically arranged; the first probe is connected with the upper end of the first synchronous increasing part; the second probe is connected with the upper end of the second synchronous increasing part; the first filament carrying part is connected with the first synchronous increasing part; the second filament carrying part is connected with the second synchronous increasing part; a carrying space for carrying a filament to be tested is formed between the first filament carrying part and the second filament carrying part; the first filament carrying part and the second filament carrying part vertically carries the filament in the carrying space upwardly till the filament is in electric contact with the first probe and the second probe so as realize testing. The filament increasing lighting device improves the lighting speed, is high in steadiness and reliability, has the characteristics of steady movement, small noise, high speed, small size and high production efficiency, and reduces the filament producing cost.
