Problems solved by technology

But this kind of scheme first requires to make a suitable small core column, and the production of this small core column is quite difficult in terms of technology, which will obviously affect the qualified rate of product production
On the other hand, shortening the total length of the filament will reduce the distance between the two guide wires connecting the two ends of the filament, thereby reducing the coating amount of electronic powder, thereby reducing the life of the fluorescent tube

Embodiment 1

[0017] Embodiment 1: As shown in Figure 1, a fluorescent tube with a small diameter includes a glass tube 1 and a filament assembly 2, the filament assembly 2 includes a filament 3 and two guide wires 41, 42 connected to the two ends of the filament 3, A nickel sheet sleeve 5 is arranged beside the filament 3, and the filament 3 is arranged in the nickel sheet sleeve 5. The nickel sheet sleeve 5 is provided with a connecting piece 6, and the connecting piece 6 is connected with a guide wire 41 by spot welding, and is connected with another guide wire 41 by spot welding. One guide wire 42 is not in contact, the two guide wires 41, 42 are provided with a glass column 7 sintered and fixed with the glass tube, and the nickel sleeve 5 is provided with an auxiliary protective sheet 8 extending radially outward.

Embodiment 2

[0018] Embodiment 2: As shown in FIG. 2 , other structures are the same as Embodiment 1, except that the glass column 7 is replaced by a horn tube 9 .

Embodiment 3

[0019] Embodiment 3: As shown in Figures 3 and 4, a fluorescent tube with a small diameter includes a glass tube 1 and a filament assembly 2, the filament assembly 2 includes a filament 3, and two guide wires 41 connected to both ends of the filament 3 , 42 and the trumpet tube 9 that is sealed and fixed on the end of the glass tube 1 are horizontally provided with a protective support rod 10 relative to the direction of extension of the guide wire 41,42, and the length of the protective support rod 10 is greater than that of the filament 3 in the guide wire 41,42. The length after being fixed, the protective support bar 10 and two guide wires 41, 42 are welded and fixed, and the two welding points are insulated from each other. Contacted nickel ring 12 is realized, of course, other schemes can also be adopted.

[0020] In the above embodiments, the glass tube 1 may be a spiral glass tube, may also be a U-shaped glass tube, or may be a glass tube of other shapes.

Abstract

The invention discloses a fluorescent tube with a fine pipe diameter, comprising a glass tube and a filament component, wherein the filament component comprises a filament and two conducting filaments which are connected with two ends of the filament. The fluorescent tube with a fine pipe diameter is characterized in that a wall-against protection device is arranged beside the filament, the wall-against protection device is fixedly connected with the conducting filaments. The fluorescent tube with a fine pipe diameter has the advantages of preventing the filament and the wall of the glass tube from being contacted with each other when a sample is processed and guaranteeing the coated weight of electron power without shortening the total length of the filament, thereby prolonging the service life of the fluorescent tube; meanwhile, both the production efficiency and the percent of pass of the product are obviously raised because the phenomenon of the filament being contacted with the wall does not exist.

Description

technical field [0001] The invention relates to a fluorescent lamp, in particular to a fluorescent lamp with a small diameter. Background technique [0002] Existing fluorescent tubes are provided with filament assemblies such as stems at both ends, but for fluorescent tubes with small diameters, especially energy-saving lamps with a diameter below φ6mm, due to the small diameter, There is a phenomenon that the filament is easy to touch the wall of the lamp tube when making the seal. When the filament touches the wall of the lamp tube, there is a great potential safety hazard in the fluorescent lamp. When the life of the fluorescent lamp ends, the contact between the filament and the wall of the lamp tube is likely to melt or burn through. In addition, when the filament touches the wall of the lamp tube, the electronic powder of the filament is also likely to be sputtered onto the wall of the lamp tube, which may easily cause early blackening, thereby affecting the life of ...
