Abstract
The utility model relates to a fluorescent lamp tube, which is composed of a glass tube, fluorescent material, and a cathode electrode. The utility model is characterized in that the lamp filaments on the cathode electrode is additionally provided with a plurality of protecting filaments to protect the lamp filament, the bombardment of mercury ion to the lamp filaments can be reduced, the exfoliation, or the sputtering, or the evaporation of the electronic powder on the lamp filaments can be decreased in order to be helpful to the heat dispersion of the lamp filaments, and the hot-spot temperature can be decreased. The service lives of the lamp tubes can be prolonged.
Description
The utility model relates to a kind of basic electrical component, specifically a kind of fluorescent tube.
We know, existing fluorescent tube is of all kinds, but its basic structure mainly is made up of glass tube, fluorescent material, negative electrode etc., and wherein, fluorescent material is coated in the glass tube inwall, and two negative electrode sealing-ins are at the glass tube two ends, and cathode filament is connected with seal wire.The weak point of this fluorescent tube is that filament is subjected to the bombardment of mercury ion serious, and the easy loss of electronics powder on it influences fluorescent tube useful life.
The purpose of this utility model is exactly in order to overcome short deficiency of existing fluorescent tube life-span, and a kind of simple in structure, long-life fluorescent tube that cost is suitable with existing fluorescent tube is provided.
For achieving the above object, a kind of fluorescent tube is made up of glass tube, fluorescent material, negative electrode, and fluorescent material is coated on the glass tube inwall, and the negative electrode sealing-in is in the two-port of glass tube, and cathode filament is connected with seal wire, it is characterized in that seal wire is provided with some protection silks.
The said protection silk of the utility model can be connected any position of glass tube inner guide wire.Metaphor can be put and be welded in the seal wire middle part, also can be connected the contact place of seal wire and filament.The protection silk can be established some, likens one, two, three, four, and can be processed into various shape, and is crooked around filament.Protection silk material therefor can be used metal materials such as tungsten filament, nickel wire.
Glass tube of the present utility model can be processed into various shape, as H type, U type, two O types etc.
The utility model is owing to set up the protection silk on the seal wire; reduced the bombardment degree of mercury ion to filament; the coming off of electronics powder on the filament, sputter or evaporation degree have been reduced; and help filament heat radiation, reduce its hot(test)-spot temperature; thereby improved the useful life of fluorescent tube greatly, it is simple in structure, cost is suitable with existing filament.
Below in conjunction with accompanying drawing embodiment of the present utility model is further described:
Fig. 1 is the utility model structural representation, also is the schematic diagram of embodiment.
As can be seen from Figure 1, a kind of fluorescent tube is made up of glass tube 1, fluorescent material 2, negative electrode, and fluorescent material 2 is coated in the inwall of glass tube 1, and two negative electrodes use stem stem sealing process binder at glass tube 1 two ends.The filament 3 on the negative electrode and the contact place of seal wire 4 are provided with four protection silks a, b, c, d, and wherein a, b are nickel wires, and length is 2～5mm; c, d are tungsten filaments; length is 1.5～3mm, and they can be the terminations that filament 3 directly stays when being connected with seal wire 4, also spot welding processing in addition.
This fluorescent tube is a double-H groove weld 9W fluorescent tube, has set up four protection silks on seal wire, and through contrast test, provide one times or more than existing fluorescent tube the useful life of this fluorescent tube, reaches more than 5000 hours, and the life-span improves greatly.
Claims (2)
1, a kind of fluorescent tube is made up of glass tube, fluorescent material, negative electrode, and fluorescent material is coated on the glass tube inwall, and the negative electrode sealing-in is in the glass tube two-port, and cathode filament is connected with seal wire, it is characterized in that seal wire is provided with the protection silk.
2, fluorescent tube as claimed in claim 1 is characterized in that said protection silk is located at the contact place of seal wire and filament.
