Abstract
The utility model relates to a lamp tube, which is mainly a fluorescent lamp tube for illumination, wherein, both ends of the lamp tube are mainly provided with cavities respectively; the diameter of the cavity is larger than the diameter of the lamp tube; two filaments are respectively positioned on the central position of the two cavities and connected with electrodes of a tube seat; consequently, a special-shaped lamp tube is formed. The utility model reduces that hot electric pyrogenic substances one the surfaces of the filaments are vaporized, leads to both of the two ends of the lamp tube to not blacken, extends service life of the lamp tube and does not influence normal lighting.
Description
The utility model relates to a kind of fluorescent tube, mainly refers to illuminating fluorescent tube.
At present, fluorescent tube commonly used has the luminous efficiency height, advantages such as power saving, and still, lamp tube ends is turned black easily in the use, greatly reduces the useful life of fluorescent tube, brings bad influence for work, study, causes unnecessary economic loss.
The purpose of this utility model provides a kind of novel long-life fluorescent tube, not influencing under the normal luminous preceding topic of fluorescent tube, lamp tube ends is no longer turned black, and has prolonged the useful life of fluorescent tube.
For achieving the above object, long-life fluorescent tube of the present utility model is made up of base, electrode, filament support, filament, inert gas, special-shaped fluorescent tube and fluorescent material, and the insulation board that filament forms one by filament support and special-shaped fluorescent tube and passes base links to each other with electrode; Special-shaped fluorescent tube sets up a diameter to form greater than the cavity of common tube diameter respectively at the two ends of common fluorescent tube; Two filaments occupy the center of corresponding cavity respectively.
This cavity can be a ball-shaped.
This cavity also can be a column type.
Owing to adopted such scheme: the distance of the ball-shaped cavity outer wall of filament and special-shaped lamp tube ends or column type cavity outer wall increases, reduced the evaporation of filament surface heat electronic emitting material, lamp tube ends is no longer turned black, prolonged the useful life of fluorescent tube, help working and learning, reduced economic loss.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the cutaway view of the utility model long-life first embodiment of fluorescent tube.
Fig. 2 is the cutaway view of the utility model long-life another embodiment of fluorescent tube.
Long-life fluorescent tube shown in Figure 1 is made up of base 1, filament support 2, filament 3, electrode 4, special-shaped fluorescent tube 5, fluorescent material 6, ball-shaped cavity outer wall 7, lamp line support 8, filament 9, electrode 10, ball-shaped cavity 11, ball-shaped cavity outer wall 12, ball-shaped cavity 13, insulation board 14, insulation board 15, inert gas 16, base 17, base 1 links to each other with the ball-shaped cavity outer wall 7 of special-shaped fluorescent tube 5 left ends by adhesive, and filament 3 occupy the center of ball-shaped cavity 11 and fixes by filament support 2.Filament support 2 merges into an organic whole with ball-shaped cavity outer wall 7, filament 3 passes filament support 2 and links to each other with electrode 4 with insulation board 14 on the base 1, base 17 links to each other with the ball-shaped cavity outer wall 12 of special-shaped fluorescent tube 5 right-hand members by adhesive, filament 9 occupy the center of ball die cavity 13, and fixing by filament support 8.Filament support 8 merges into an organic whole with ball-shaped cavity outer wall 12, and filament 9 passes filament support 8 and links to each other with electrode 10 with insulation board 15 on the base 17.Filament support 2 special-shaped fluorescent tubes 5 and filament support 8 constitutes annular seal spaces, in be coated with fluorescent material 6, interior filling with inert gas 16.
Fig. 2 has provided the cutaway view of another kind of long-life lamp tube, and the fluorescent tube of long-life shown in the figure is made up of base 1, filament support 2, filament 3, electrode 4, special-shaped fluorescent tube 5, fluorescent material 6, column type cavity outer wall 7, lamp line support 8, filament 9, electrode 10, column type cavity 11, column type cavity outer wall 12, column type cavity 13, insulation board 14, insulation board 15, inert gas 16, base 17.Wherein adopted the structure of the special-shaped lamp tube ends cavity of another kind of formation.Set up two column type cavitys 11 and 13 respectively in special-shaped lamp tube ends, filament 3 and filament 9 occupy the center of column type cavity 11 and column type cavity 13 respectively.
Claims (3)
1, a kind of long-life fluorescent tube, form by base, electrode, filament support, filament, special-shaped fluorescent tube, fluorescent material, inert gas, it is characterized in that: the two ends of special-shaped fluorescent tube (5) have been set up two cavity (11) and (13) bigger than common fluorescent tube diameter respectively, and filament (3) and filament (9) occupy the center of two cavitys of correspondence respectively.
