Problems solved by technology

However, the phenomenon of "sputtering" and "evaporation" generated during the ignition process of the lamp tube make the actual service life of the fluorescent lamp far from the calculated service life, thus reducing the price-function ratio of the fluorescent tube.

Embodiment Construction

[0012] figure 1 Among them, the two filaments 6 and 7 are respectively installed on the fixed electrode guide wire 4 and the fixed electrode guide wire 5 on the stem column of the electrode bracket 2, and the two filaments 12 and 13 are respectively installed on the fixed electrode guide wire on the stem column of the electrode bracket 3. On the filament 10 and the fixed electrode guide wire 11, after the four filaments are respectively coated with electronic powder, the electrode holder 2 and the electrode holder 3 have two electrodes respectively, and the electrode holder 2 and the electrode holder 3 are put into the two input terminals of the phosphor tube. In the end, the bell mouths 9, 14 of the stem are respectively sealed and fixedly connected with the two input ports 8, 15 of the powder tube of the fluorescent lamp, and processed into a finished tube of a double-electrode fluorescent lamp through other lamp-making processes. Due to the physical process of starting the ...

Abstract

The invention discloses a double-electrode fluorescent tube, which is characterized by the following: setting two bars of electrode on electrode rack of fluorescent tube two ends; proceeding discharging phenomenon for cathode of low resistance value; lengthening utility lifetime of double-electrode fluorescent tube than present tube; improving price function rate; simplifying the structure.

Description

technical field [0001] The invention relates to an electrode support device of a fluorescent lamp, in particular to a double-electrode fluorescent lamp. Background technique [0002] The performance of electrodes for fluorescent lamps is one of the key factors affecting the life of fluorescent lamps. Since the advent of fluorescent lamps, people have continued to conduct research on electrode materials, shapes, structures, winding methods, electrode electron emission materials (electron powder) composition and coating methods, and the decomposition and activation process of electrode emission materials during the exhaust process. Research, in order to improve the technical performance of lamp electrodes, and make continuous progress in reducing the escape power of electrode electron emission materials and ion bombardment resistance, so that the technical performance of existing fluorescent lamp electrodes is continuously improved, and the service life of the lamp reaches 800...
