The invention discloses an energy-saving fluorescent lamp with automatically formed by a single step, and the forming method and the mould of the U-shaped tube unit. The energy-saving fluorescent lamp is formed of several single-tube units which are connected to each other with connective bridges, additionally, two walls of one tube unit are parallel to each other, and two walls also are adjacent tightly to each other. The bending direction of the two walls is the same. The advantages of the lamp are effective light utilization, short tube length, and sufficient radiation, and the lamp is automatically single forming in industry Therefore, the lamp can work with small power, and also has low cost, high efficient, and low rejection ratio.
An automatic one-shot-modeled compact fluorescent lamps (CFL) discharge tube typically constituted of several said discharge tubes, wherein said discharge tube appears to an U-shaped glass tube with two close parallel leg tubes, and said both parallel leg tubes are bent to a curve with a certain curvature radius simultaneously, just as appearing to “)” shape in the side view.
A method of manufacturing the automatic one-shot-modeled compact fluorescent lamps (CFL) discharge tube, wherein the procedures are to follow the below steps:
A modeling die used for manufacturing the automatic one-shot-modeled compact fluorescent lamps (CFL) discharge tube typically includes a cavity die and a male die, wherein the die parting face is formed along with curved axils of the discharge tube so that the U-groove is divided two half-portions respectively formed on the cavity die and the male die along with the die parting face, the cross-section of the U-groove on each die appears to half circle.
