This invention relates to C type bulb center column construction., The main characteristic consists in a mass to combine the tie two lead wires, should combine central pivot tie of mass a the center tube present the cross shape, make two lead wires because of in the center tube however compartment two side end. Make the tungsten silk anti because of concentration by two the sides keep a safe space to let divide equally draw apart get anti is interlacing short, and the drubbing one construction do not share the space and then order the lamp turn down the heat energy to lift to increase the service life. This case differ early times center column depend on oviduct, center column composition piece complicated, manufacture to do not occupy the bigger space easily to wait for the defect, energy doubly life compliant reduction production process, promote the quality stability application capability.
