Abstract
The utility model relates to a multi-pole fluorescent lamp, which is composed of the parts of a glass shell, core posts, leads, a lamp foot, wiring terminals, pins, etc. The multi-pole fluorescent lamp is characterized in that two groups of lamp filaments are arranged on each core post; two groups of lamp filaments are led out by three leads, wherein, one lead is a common lead; the lamp foot has four wiring terminals and two pins; the pins can respectively lead out any one group of two groups of lamp filaments. The multi-pole fluorescent lamp has the advantage that after one group of lamp filaments are not valid, the other group of lamp filaments can be enabled to prolong the service life of the lamp tube to two times.
Description
The utility model relates to a kind of electric light source, refers to fluorescent lamp especially.
At present, known fluorescent lamp all has only two negative electrodes, and each negative electrode all has only one group of filament, and after the sputter of electronics material finished when filament distillation fusing or it on, fluorescent lamp just can not normally start, and fluorescent tube is scrapped.
The purpose of this utility model is the useful life of prolonging lamp tube.
The purpose of this utility model is achieved like this: each negative electrode of fluorescent tube has two groups of filaments, and its specification is identical, and two groups of filaments are drawn by three lead-in wires, and wherein one is common lead.Like this, after one group of filament is invalid, can enable another group filament, lamp tube service life is prolonged.
The utility model has the advantages that the useful life that can prolong fluorescent lamp, improve the cost performance of fluorescent lamp.
Below, be example with the straight pipe type fluorescent lamp, the utility model is described in further detail in conjunction with the accompanying drawings:
Accompanying drawing 1 is the cutaway view of fluorescent tube one end, wherein:
The 1-glass bulb; The 2-filament; The 3-stem stem; The 4-lead-in wire; The 5-lamp base; The 6-binding post; The 7-pin.
Accompanying drawing 2 is the lamp base vertical view, wherein:
The 5-lamp base; The 6-binding post; 8-connects lead.
In the manufacture process, operation, technology and product standard are identical with conventional fluorescent lamps, only draw two groups of filaments with three lead-in wires when making stem stem, and wherein, one is common lead, and common lead is connected on the binding post that connects lead.Binding post has internal thread, and pin has corresponding external screw thread, and by being threaded, pin can be drawn a certain group of filament, is communicated with corresponding lamp holder, makes the fluorescent lamp operate as normal.After one group of filament is invalid, back out pin, pick out another group filament, lamp can work on.
Claims (1)
