Current, the application of fluorescent lamp worldwide in general lighting field is still the most widely, although LED illumination mode is just expanded fast in this field, but LED yet has and exists relative to the factor of fluorescent lamp deficiency, therefore, fluorescent lighting still can be in and the situation of depositing in following period of time and LED illumination.In view of this, still practical significance is had by improving the useful life of improving fluorescent lamp.
By summing up fluorescent light technology application practice for many years, people are in the clear and definite factors affecting fluorescent lamp useful life, first essential factor is exactly the reserves of fluorescent lamp electrode electronic powder painting, because being subject to the restriction of several factors and unsatisfactory, when the electronic powder in electrode filaments exhausts, the life-span of fluorescent lamp terminates naturally, excellent T5 fluorescent lamp citing is occupied by general performance, the lamp tube service life that current selection is reasonable, technological specification manufacturer production goes out is also only at 5000 ~ 10000 hours, and some producer's lives of product of too pursuing profits just can't bear to have commented.Due to the life-span almost direct proportionality of electronic powder reserves and fluorescent lamp, therefore the not enough problem of electronic powder reserves is solved, it is the key factor extending fluorescent lamp useful life, traditional T5 and following slim fluorescent lamp, by the restriction of fluorescent tube internal diameter and stem stem pin nickel distance between tie rods, the horizontal holding frame mode of current filament is fixed, as shown in Figure 1, cannot the increase of filament helix length that brings of receiving auger number of turns increase, thus electronic powder reserves cannot be increased, its useful life cannot be extended.
Utility model content
The purpose of this utility model is the electronic powder reserves deficiency overcoming traditional fluorescent lamp, cause the problem of the lost of life of fluorescent lamp, the fluorescent lamp electrode of the high electronic powder reserves of multi-circle spiral flow structure of the present utility model, the filament with the parallel placement of nickel bar pin is provided with between two nickel bar pins, filament is vertically fixing, increases the number of turns of filament spiral, thus increases electronic powder reserves, extend its useful life, have a good application prospect.
In order to achieve the above object, the technical solution used in the present invention is:
A kind of fluorescent lamp electrode of high electronic powder reserves of multi-circle spiral flow structure, it is characterized in that: comprise the glass stem that inside is provided with blast pipe, the one lateral edges flange formation laterally of described glass stem and the lip limit of the fluorescent lamp host glass seal of tube, two Dumet wire are arranged with in described glass stem, the end of described Dumet wire is connected with the nickel bar pin for welding filament, described nickel bar pin extends glass stem, and between two nickel bar pins, being provided with the filament of the vertical placement parallel with glass stem, described filament is the tungsten filament of multi-circle spiral flow structure.
The fluorescent lamp electrode of the high electronic powder reserves of aforesaid a kind of multi-circle spiral flow structure, is characterized in that: described filament edge is identical to the distance of both sides nickel bar pin.
The fluorescent lamp electrode of the high electronic powder reserves of aforesaid a kind of multi-circle spiral flow structure, is characterized in that: one end of described filament is fixed on the junction of side nickel bar pin and glass stem, and the other end of described filament is fixed on opposite side nickel bar pin top.
The fluorescent lamp electrode of the high electronic powder reserves of aforesaid a kind of multi-circle spiral flow structure, is characterized in that: end and the nickel bar pin of described filament adopt the mode of spot welding to fix.
