Abstract
A fluorescent lamp comprises a glass tube, an electrode at each end of the tube, each of the electrodes including a pair of lead wires extending through each sealed end of the tube and joined to a coil, and a capsule containing metal hydride disposed in the tube and having a decomposition temperature higher than temperatures within the tube during normal operation of the lamp.
Description
The present invention relates to fluorescent lamp, and relate more specifically to be useful on therein the fluorescent lamp of the device of blow-out in useful life ending.
The electric ballast that fluorescent lamp is controlled fluorescent lamp day by day and very frequently uses together.Usually so wherein open circuit voltage is enough high for " moment startup " type ballast, directly to light this lamp, negative electrode heater circuit that need not be independent.
When the emission layer that the ending in lamp useful life appears at one of electrode exhausts.With the ballast that low open circuit voltage is arranged, when first electrode failure, the electric arc of this lamp extinguishes lentamente under power line frequency.But under the situation of electronics instant start ballast, when first electrode failure, the electric arc of this lamp not necessarily will extinguish.The open circuit voltage that is provided by instant start ballast is enough high, so that this lamp continues to operate under " cold cathode " mode.At the cold cathode duration of work, this cathodic electricity is pressed with 12-50V or higher voltage.Referring to Fig. 1 and Fig. 2, in lamp 2, glass shell 8 two ends have electrode 4,6 respectively, because first electrode 6 lost efficacy ion bombardment heating tungsten coil 10, lead-in wire 12,14 and any other metal structure in glass shell 8.Being heated of hardware reaches high like this temperature, makes this element provide enough thermion and secondary to keep this electric arc.Power consumption at this inefficacy lamp end greatly increases.The result is that the heating of shell 8 these ends is away from its normal working temperature.Lead-in wire 12,14 in shell 8 may melt and by this shell and/or make shell produce the crack, sometimes because this lamp is offset from fixture breaks.The overheated lamp fixture that also makes socket or adorn lamp within it of this lamp end damages, or makes the plastic lamp base fusing.
For alleviating this problem, having designed the transient starting of extension wire electric ballast is arranged, exhaust other phenomenon of portalling with the raising of detection modulating voltage or by negative electrode, and cut-off this system.But Fu Jia electronic component has significantly increased the cost of this ballast like this.And many ballasts of such characteristic that do not comprise have been present in the existing lamp facility.
Obviously, be necessary to allow fluorescent lamp carry the device that when lamp ends up useful life, disconnects electric arc, circuit or electronic component that this disconnecting apparatus does not comprise or do not need to add.
Therefore, the purpose of this invention is to provide a kind of fluorescent lamp, it has the device that when lamp ends up useful life electric arc is disconnected.
A further object of the present invention provides a kind of fluorescent lamp that the current interruption device is arranged, circuit that disconnecting apparatus wherein must not add or electronic component.
According to above-mentioned purpose with other, and the present invention that hereinafter will illustrate is characterised in that, fluorescent lamp comprises glass tube, electrode at this each end of pipe, each electrode comprises the pair of lead wires of extending and receive coil by this seal of tube end, with the attachment of the metal hydrogenation thing cream of configuration in pipe, its dissociation temperature is higher than the temperature in this lamp normal work period pipe.
Above-mentioned and further feature of the present invention comprises the various new details of structure and parts combination, existing more specific description and pointing out in the claims in addition in conjunction with the accompanying drawings.Be understood that and embody that concrete device of the present invention only provides in the mode of example rather than as limitation of the invention.Principle of the present invention and feature can apply among the various embodiment in the case without departing from the scope of the present invention.
The accompanying drawing of being mentioned shows embodiments of the invention therein, therefrom its novel characteristics and advantage as can be seen.
In these accompanying drawings:
Fig. 1 is the front view of prior art fluorescent lamp;
Fig. 2 is the enlarged diagram of Fig. 1 lamp end;
Fig. 3 is similar to Fig. 2, but a kind of form of embodiment of the invention fluorescent lamp is shown;
Fig. 4 is similar to Fig. 3, but another form of another embodiment of the present invention fluorescent lamp is shown.
Referring to Fig. 3, the fluorescent lamp 2 that illustrates comprises glass tube 8.Each end at pipe 8 is provided with electrode 4,6 (illustrating at Fig. 3).Pair of lead wires 12,14 is managed each sealed end extension and is received coil 10 by this, to form this electrode.The attachment 30 of metal hydrogenation thing cream is configured in the pipe 8, and has than the higher dissociation temperature of temperature in the lamp normal work period pipe 8.At normal lamp duration of work, the temperature of this cream preferably is maintained at about 150 ℃ or lower.Electrode 6 is similar to shown in Figure 2ly as can be seen, but has been provided with the attachment 30 of metal hydrogenation thing on 12,14 at each lead-in wire.Attachment 30 preferably receive each end lead-in wire of pipe 8 12,14 at it from the position that glass capsulation 32 is drawn, that is to say at the interface at lead-in wire-glass capsulation.
At work, when lamp ends up useful life, exhausted causedly by the cathode emission layer at lamp one end, the temperature that is raised at the coil 10 of this end of lamp is away from its normal working temperature and is melted at last.So electric arc is linked lead-in wire 12 or 14 and the temperature of this lead-in wire that raises.Along this metal hydrogenation thing cream attachment 30 of heat thermal dissociation of this lead conduction, and hydrogen is released in the lamp.The temperature of this cream reaches 650 ℃ or higher during this.The appearance of hydrogen has improved the required voltage of maintenance discharge in the pipe 8, and it is more high than what provided by instant start ballast, and lamp is slowly extinguished, and does not have the significant temperature rise of end windings and parts or glass crack.The rapid appearance of hydrogen release is to prevent the damage to the fixture that keeps affected lamp.The amount of hydrogen release typically from about 1 torr of 5mg attachment-liter (Torr-Liter), just is enough to blow-out in big fluorescent lamp.
The most preferred embodiment of cream is by the meticulous hydride powder of 40wt% and 60wt% suspended colloidal alumina mixed preparing in water.The attachment of this cream, it is heavily about 5mg when drying, is added on 12,14 the bottom of respectively going between, and this bottom is an index wire from the position that glass capsulation 32 is drawn.
Can utilize the embodiment of other cream, comprise the binder except that the colloidal state alumina.Preferred this binder is inorganic and drying without degasification, as montmorillonitic clay and various silicate.
Referring to Fig. 4, show electrode configuration, wherein bead 40 is fixed on two lead-in wires 12,14, although attachment 30 can be added on pearl sidepiece or the off-line circle surface farthest, preferably is configured on the nearest surface of bead off-line circle 10.
Best metal hydride is titantium hydride TiH
1.7Metal ingredient in the metal hydride can be selected from following group, and this group comprises the alloy of the combination of alloy that titanium, zirconium, hafnium, these metals are mutual and these metals and other metal such as cobalt, iron, nickel, manganese, lanthanum or these other metals.
Provide the fluorescent lamp that disconnecting apparatus is wherein arranged in lamp ending in useful life thus, circuit that this device need not add or electronic component.The cost of related disconnecting apparatus is insignificant, and more much lower than the cost of open circuit is provided in ballast, although if this ballast can have been used in individual lamp useful life.
Be understood that the present invention never is subjected to suggested here and/or the restriction of shown concrete structure in the accompanying drawings, but will be included in any remodeling or equivalent in the claim protection range.
