Abstract

The utility model relates to a three-pole type fluorescent lamp. The middle part of the lamp tube of an ordinary fluorescent light is additionally provided with an electric pole D, which makes the distance between electric poles reduced by one half; under the same self-inductance voltage, the gas of the lamp tube is easier of ionization and discharge and therefore, generates glow starting; the flash frequency of the glow starting is reduced; the glow starting time is shorted, and thus the service life of the fluorescent lamp is extended. The utility model can be used to replace the available fluorescent lamps.

Description

Three-pole type fluorescent lamp

The utility model relates to a kind of fluorescent lamp.

In the prior art, will flash with the fluorescent lamp of starter starting repeatedly could starter.Under the low voltage, it is more that fluorescent lamp flashes number of times, and starting time is longer, serious to the influence in useful life.Joining fluorescent lamp with " omnipotent switch for fluorescent lamp " (number of patent application 89215405.5) uses, though saved starter, starter does not flash, prolonged fluorescent lifetime widely, starting time is short under the normal voltage, but also dislike long slightly in following starting time of low-voltage very, and need to increase by two lead-out wires (causing switch) from the starter base two ends of fluorescent lighting fixture.

The purpose of this utility model is to overcome the deficiency of above prior art and a kind of three-pole fluorescent lamp is provided.

The purpose of this utility model can reach by following measure: only need to add an electrode D at the middle part of common fluorescent lamp (comprising H type fluorescent lamp, Fluorescent lamp without filament) fluorescent tube.The end of electrode D inserts the middle part of fluorescent lamp, another termination zero-power line.

Fig. 1 is that the utility model need be used starter starting circuit figure.

Fig. 2 is that the utility model is joined the starting circuit figure that omnipotent switch for fluorescent lamp uses.

The utility model is described in further detail below in conjunction with accompanying drawing:

With reference to Fig. 1, three-pole daylight lamp glow starting principle is identical with common fluorescent lamp.Difference is, adds an electrode D at the middle part of fluorescent-lamp tube, and electrode D can use copper cash, also available other high temperature resistant conductor manufacturing.The end of electrode D inserts the middle part of fluorescent lamp, another termination zero-power line.Because electrode D at fluorescent lamp middle part, makes between electrode (common fluorescent lamp is between two filaments) distance dwindle half, under same self induction voltage, make in the pipe gas more easily ionizable discharge and build-up of luminance.Therefore reduce starter and flashed number of times, shortened starting time, prolonged fluorescent lamp useful life.With reference to Fig. 2, it is identical that three-pole daylight lamp glow starting principle and common fluorescent lamp are joined omnipotent switch for fluorescent lamp starter principle.But because three-pole fluorescent lamp interelectrode distance dwindles half, therefore starter is easier under low-voltage very, shortens starting time.And make fluorescent lighting fixture (joining the utility model) not only save starter base, and only need increase a lead-out wire (cause K2 from filament, more common fluorescent lamp has reduced by a lead-out wire).

Without electrode D, the three-pole fluorescent lamp can be worked as common fluorescent lamp and be used.

The utility model is novel original, and is simple in structure, and the more common fluorescent lamp of starter is easy, and the time is short, flashes and lacks, and the life-span is long, joins the Universal daylight lamp switch use and can reduce by a lead-out wire. And easy to manufacture, only need to add an electrode at common fluorescent lamp middle part, cost that every fluorescent lamp increases is seldom installed also very convenient. Have good market prospects.

Claims

1, a kind of three-pole fluorescent lamp is characterized in that adding an electrode D at the middle part of common fluorescent lamp, and the end of electrode D inserts the middle part of fluorescent tube, another termination zero-power line.
