Below utilize accompanying drawing, describe the execution mode of starter of the present invention and manufacture method thereof in detail.And identical position owing to be of identical composition and shape, produces identical effect, so omit its explanation sometimes.
(execution mode 1)
Fig. 1 is the part sectioned view of an example of expression starter of the present invention.
The starter 1 of present embodiment 1 has electrode (float electrode) 3, electrode (counter-electrodes) 4 and the discharge gas paired with above-mentioned float electrode 3 in the inside of airtight container 2 (internal tank 8).
The starter 1 of present embodiment is owing to adopting said structure, so can shorten the dark place start delay time.Starter 1 comprises the electron emission part 18,19 that work function is little and be activated, so, for example in the dark take care of starter 1 for a long time and also can be easy to emitting electrons.
The material of tubaeform stem stem 7 is the glass that contains potassium, still, so long as, do not limit especially comprising that with electron emission part 18,19 contacted surfaces the alkali metal that contains potassium supplies with the material of material.
The shape of tubaeform stem stem 7 is the such shapes of umbrella, and is the structure of the end of the shirt rim portion open side that is encapsulated in shell 6, is this shape but be not particularly limited.
The material of shell 6 is if can tolerate the material of above-mentioned discharge and heating, and just not specific qualification generally adopts glass, resin etc. to get final product.
The shape of shell 6 is the general cylindrical shape that the end is blocked, is this shape but be not particularly limited.
Discharge gas is so long as be fit to the gas of discharge and just be not particularly limited.Generally can adopt a kind of gas of from helium, neon, argon and xenon, selecting or their mist etc. to get final product.Especially the suitable mist that adopts argon gas or neon and argon.
As long as can begin and continuous discharge just is not particularly limited the enclosed volume of discharge gas, the air pressure that can make internal tank 8 is in number kPa~number 100kPa, preferably 1~10kPa.
The material of inner lead 13,15 for example can adopt iron and iron-nickel alloy etc. so long as contain the material of iron and just be not particularly limited.
We can say that tubaeform stem stem 7 is that the alkali metal that contains potassium is supplied with material with 18,19 contacted of electron emission part, the periphery that comprises this face or whole tubaeform stem stem 7.
Applying of the direct voltage of above-mentioned pulse type, if according to the condition of electrode 3,4 not short circuits, promptly bimetallic element 14 inactive conditions apply, so, to the size of voltage (crest voltage and minimum voltage etc.), stopping period and pulse duration etc. is not particularly limited.And, the direct voltage of above-mentioned pulse type is not limited especially, both can be the sinusoidal wave voltage of control, also can be the voltage of control square wave, if but the offset of sinusoidal ripple cuts off the voltage (for example be controlled to during 1 second discharge 2 times voltage) of control, just can control at an easy rate, so preferred.And, if utilize step-up transformer to general alternating voltage (60Hz for example, the voltage that 0.2kV) boosts, then cheap, so preferred.
Applying of the direct voltage of above-mentioned pulse type, for example with each single electrode of electrode 3,4 as negative electrode, direct voltage with crest voltage 0.2kV~1.0kV, minimum voltage 0kV~0.2kV, pulse repetition period 0.1 time/second~10 times/second, pulse duration 0.5ms (millisecond)~10ms, apply 0.1 hour~1.0 hours, can distinguish active electron emission part 18,19 like this.Especially, wish to apply the direct voltage of crest voltage 0.6kV~0.8kV, minimum voltage 0kV~0.1kV, pulse repetition period 1.0 times/second~4.0 times/second, pulse duration 1.0ms~4.0ms.
If above-mentioned crest voltage surpasses 1.0kV, then electric shock waits fail safe that problem is arranged, if less than 0.2kV, does not then begin discharge sometimes.And, if above-mentioned crest voltage is 0.6kV~0.8kV, just too high caused, the peripheral part of the tubaeform stem stem 7 of inner lead 13,15 paradoxical discharge such as discharge only for example of crest voltage can not take place, the active electron emission part 18,19 expeditiously, are more preferably.
If above-mentioned pulse duration surpasses 10ms, then the heat of Chan Shenging is many, and bimetallic element 14 can be movable, if less than 0.5ms, then must shorten the energising cycle, and for example generation sometimes such as has when not discharging at loss.And, if above-mentioned pulse duration is 0.5ms~6.0ms, perhaps be more preferably 1.0ms~4.0ms, do not make bimetallic element 14 activities, the active electron emission part 18,19 expeditiously.
And, if the direct voltage to above-mentioned pulse type is controlled, the formed energising cycle of the discharge that produces between electrode (light period) is become 0.5 time/second~6 times/second, be preferably 1.0 times/second~4.0 times/second, so, because the heat that takes place is little, so, bimetallic element 14 inertias, and can be with active electron emission part 18,19 expeditiously of shorter time.
Here, the method that electron emission part 18,19 is activated is described.
In the internal tank 8 of having enclosed discharge gas,, then between electrode, produce discharge if between electrode 3 and electrode 4, be that negative electrode applies voltage with electrode 4.At this moment, utilize the ion in the discharge gas that the electrode 4 as negative electrode quickens, clash into the impurity on the surface of electron emission part 19, so the surface of electron emission part 19 is cleaned.And if apply above-mentioned voltage, then the tubaeform stem stem 7 as alkali metal supply material is heated, and alkali metal carries out thermal diffusion.Therefore, at the electron emission part 19 that is cleaned and tubaeform stem stem 7 contacted surface adsorption alkali metal, the work function of electron emission part 19 (drawing a needed least energy of electronics from metal) descends.Because easily from the low part emitting electrons of work function, so electron emission part 19 is activated.Equally, as if being that negative electrode applies voltage with electrode 3, then the work function of electron emission part 18 descends, and is activated.
The starter of Huo Deing like this, when the starting starter, the initiating electron quantity delivered of electrode 3,4 increases, so, can start with the short time, also can shorten the dark place start delay time.
Generally, even on starter, apply direct voltage, certain voltage for example continuously, also can be on the electron emission part 18,19 fully before the absorption alkali metal, bimetallic element 14 contact inner leads 15, thereby inter-electrode short-circuit also stops discharge, so electron emission part 18,19 is not activated.And even apply alternating voltage, inter-electrode short-circuit too is not so electron emission part 18,19 is activated.But, by applying the direct voltage of pulse type, electron emission part 18,19 is activated with the short time.
The action of the starter 1 when using starter 1 to light fluorescent lamp (not having diagram) is described here.
If on the electrode 3,4 of starter 1, apply the voltage of regulation, then between electrode, produce glow discharge.Utilize the heat of this glow discharge, bimetallic element 14 distortion, i.e. electrode 3 activities contact with electrode 4.Like this, short circuit current flows through, and the filament electrode of fluorescent lamp (not having diagram) is preheated.And, if electrode 3,4 contacts with each other, short circuit current flow then, glow discharge stops.But if short circuit current flow, then bimetallic element 14 then is cooled, so, be deformed into original shape, that is to say that electrode 4 is left in electrode 3 activities, short circuit current also stops.At this moment, produce pulse voltage, in fluorescent lamp, produce discharge, light fluorescent lamp.
That is to say, relate to electron emission part the 18, the 19th of the present invention, can launch the initiating electron that much is used to make starter 1 beginning glow discharge.
In the starter 1 of present embodiment, the potassium of supplying with from tubaeform stem stem 7 is adsorbed by applying above-mentioned voltage in the surface of preferred above-mentioned electron emission part 18,19.This be because, electrode 3,4 is in the electron emission part 18,19 of having adsorbed potassium, work function further reduces.
In the starter 1 of present embodiment, the direct voltage that preferably is applied to the above-mentioned pulse type on the electrode 3,4 has stopping period.If starter 1 is applied high voltage, then the temperature of float electrode 3 sharply raises immediately, bimetallic element 14 activities and short circuit.
In the starter 1 of present embodiment, wish that electron emission part 18,19 is containing from iron with tubaeform stem stem 7 contacted surfaces and comprising at least a metal of selecting the alloy of iron.This is because the work function of electron emission part 18,19 further reduces on the surface of the electron emission part that contains iron.
In the starter 1 of present embodiment, preferred tubaeform stem stem 7 is the glass that contains alkali metal oxide, especially wishes it is the glass that contains potassium oxide.If being included in the glass, chemically unsettled alkali metal chemically becomes stable, so handle easily.And, because the alkali metal of supplying with from above-mentioned glass exists as ion in this glass, especially potassium is when having applied the direct voltage of pulse type, potassium ion carries out diffusion into the surface, has the character that is adsorbed on the ferrous metal surface and forms the good electron emission part of electron emissivity easily.Above-mentioned glass also have with as the good effect of the electrode compactness of metal.Above-mentioned glass is that the glass that generally is used for discharge tube gets final product, and for example suitably is used in combination K
2O, SiO
2, Na
2O, Li
2O, Al
2O
3, Fe
2O
3Deng getting final product.Especially preferably the glass that contains the potassium of 1 weight %~20 weight %.
In the starter 1 of present embodiment, preferred as alkali is supplied with at least a portion that material constitutes above-mentioned closed container.Because can reduce the member of starter.
In the present embodiment, adopted fixed electrode, but also can be float electrode as counter-electrodes 4.That is to say, in the pair of electrodes can be one and be float electrode, also can be two and be float electrode.
In the present embodiment, electron emission part 18,19 is arranged at least a portion as the inner lead 13,15 of the metal that comprises iron, is electrically connected with electrode and supplies with material with alkali metal and contact and get final product, just do not limit especially at internal tank 8.For example, also the part that can cover with iron in the part on the surface of other metal materials that will be suitable as electrode most and will cover and peel off that it is a part of and expose the part of iron as the surface of the lead-in wire of the metal that comprises iron with other metals is provided with electron emission part.In addition, also can only on an electrode, electron emission part be set.And alkali metal supply material does not contact with electron emission part 18,19 and can be activated.If contact, just absorption is supplied with the potassium that material is supplied with from alkali metal easily.
In the present embodiment, tubaeform stem stem 7 is also used as alkali metal supplies with material, still, contain potassium and contact, then restriction especially such as its shape with electron emission part 18,19 as long as alkali metal is supplied with material.For example, also can be with inner lead on the different member of the contacted tubaeform stem stem of electron emission part of (perhaps on the bimetallic element).
