Abstract
The utility model discloses a fluorescence lamp tube with thin tube diameter, which includes a glass tube and a filament subassembly. The filament subassembly includes a filament and two guide wires connected at the two ends of the filament. The utility model is characterized in that a wall impingement protective device is arranged at the side of the filament; the wall impingement protective device is connected with the guide wires. The utility model has the advantage that the collision between the filament and the glass wall can be avoided during the manufacture, the total length of the filament does not need to be shortened, and the coating quantity of the electron powder is ensured; thereby, the service life of the fluorescence lamp tube is increased. Meanwhile, the wall impingement of the filament is not needed to be worried about; thus, the producing efficiency and the qualified rate of the product are both obviously increased.
Description
Technical field
The utility model relates to a kind of fluorescent tube, especially relates to a kind of fluorescent tube of slim pipe diameter.
Background technology
Traditional fluorescent lamp tube is provided with the filament assembly such as stem stem at its two ends, but fluorescent tube for slim pipe diameter, especially at present the power saving fluorescent lamps of caliber below φ 6mm that uses because caliber is less, exists the phenomenon that filament easily bumps lamp tube wall when making is sealed.Filament is run into lamp tube wall then makes fluorescent lamp exist very big potential safety hazard, at the end easily makes filament and the fusion of lamp tube wall contact position or burns in the fluorescent tube life-span.Filament is run into lamp tube wall the filament electronic powder is splashed on the lamp tube wall in addition, easily causes early stage blackout phenomenon, thereby influences the life-span of fluorescent tube.
In order to improve above defective, the mode that the filament length overall is shortened in the main at present employing of people increases the gap between filament and the lamp tube wall, thus the phenomenon of avoiding filament to be rebuffed.But this scheme at first requires to make suitable little stem stem, and the making of this little stem stem on technology suitable difficulty, will obviously influence the qualification rate of production.On the other hand, shorten the length overall of filament, the distance between two seal wires that connect the filament two ends is reduced, thereby reduce the coated weight of electronics powder, and then the life-span of reducing fluorescent tube.
The utility model content
Technical problem to be solved in the utility model provides and a kind ofly can effectively prevent the filament phenomenon of being rebuffed, and improves the fluorescent tube of the slim pipe diameter of fluorescent lifetime.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of fluorescent tube of slim pipe diameter, comprise glass tube and filament assembly, described filament assembly comprises filament and two seal wires that are connected with described filament two ends, described filament is other to be provided with rebuffed protector, and described rebuffed protector is fixedly connected on the described seal wire.
Described rebuffed protector can comprise a nickel sheet sleeve, described filament is arranged in the described nickel sheet sleeve, described nickel sheet sleeve is provided with brace, described brace is connected with a seal wire spot welding in two seal wires, and described seal wire is provided with the glass column that is sintered to fix with described glass tube.
Described nickel sheet sleeve is provided with the auxiliary protection sheet that radial outward is extended.
Described filament assembly can also comprise that involution is fixed on the oviduct of described glass tube end, described rebuffed protector can comprise a nickel sheet sleeve, described filament is arranged in the described nickel sheet sleeve, described nickel sheet sleeve is provided with brace, and described brace is connected with a seal wire spot welding in two seal wires.
Described filament assembly can comprise also that involution is fixed on the oviduct of described glass tube end, described rebuffed protector can be the ballistic support bar with respect to the bearing of trend horizontally set of described seal wire, the length of described ballistic support bar is greater than the length of described filament after fixing on the described seal wire, described ballistic support bar is weldingly fixed on described two seal wires, mutually insulated between two solder joints of described ballistic support bar.
Described glass tube can be spiral glass pipe, also can be the U-shaped glass tube, can also be the glass tube of other shape.
Compared with prior art, advantage of the present utility model is rebuffed protector to be set in that filament is other, can prevent that filament and glass tube walls from colliding man-hour adding like this, does not need to shorten the filament length overall, guaranteed the coated weight of electronics powder, thereby improved the life-span of fluorescent tube; And being set, the protector of being rebuffed also can production efficiency of products and qualification rate all be significantly improved because of the generation that does not need to worry the rebuffed phenomenon of filament; The brace that nickel sheet sleeve is provided be connected with a seal wire spot welding in two seal wires or two solder joints of ballistic support bar between mutually insulated, both can play fixation, the while also can be avoided two seal wire conducting short circuits; Glass column is set on seal wire, can adopts the mode of glass column sintering or clamp to seal, can more successfully realize sealing process; The utility model is suitable for the following glass-tube of φ 6mm (U type, spiral all can).
