Description
Technical field
The present invention relates to a kind of light source (light source), and particularly relate to a kind of dielectric barrier discharge lamp (dielectric barrier discharge lamp).
Background technology
In the prior art, United States Patent (USP) the 4th, disclose a kind of cylinder type dielectric barrier discharge lamp pipe for 837, No. 484, this dielectric barrier discharge lamp pipe comprises pipe, an outer tube, one first electrode (electrode), one second electrode and a discharge gas (discharge gas) in one.Wherein, interior pipe is disposed at the inside of outer tube.First electrode is positioned at the outer surface of outer tube, and second electrode is positioned at the inner surface of pipe, and discharge gas then is disposed between interior pipe and the outer tube.By between second electrode and first electrode, imposing an alternating voltage, can make discharge gas be excited and emit beam.Above-mentioned discharge gas is xenon (Xe), argon (Ar) and krypton inert gases such as (Kr), or fluorine (F
2), chlorine (Cl
2) wait halogen gas, and the gas pressure of being inserted is usually between 143 torrs (torr)～480 torrs (torr).The dielectric barrier discharge lamp pipe is understood the difference because of the gaseous species of being inserted, and sends the light of different wave length (for example being 172nm, 222nm and 308nm).The light of these different wave lengths can be applied on the various purposes.To clean electronic component is example, in order to decompose attached to the organic compound on the electronic component, can provide wavelength to be about the light of 172nm.At this moment, just can use the dielectric barrier discharge lamp pipe that is filled with xenon (Xe) to carry out the decomposition of organic compound, to reach the purpose of cleaning electronic component.
For second electrode of above-mentioned cylinder type discharge lamp is known many kinds structures and manufacture method arranged, be described as follows now.Second electrode of traditional round cartridge type dielectric barrier discharge lamp pipe is a bar-shaped metal, directly inserts in the caliber of interior pipe.General discharge lamp uses quartz ampoule (quartz tube) as interior pipe.Yet quartz ampoule all can produce distortion tolerance slightly in manufacture process, so that metal bar is difficult to and the inner surface of quartz ampoule fits tightly fully, that is has the space between this kind second electrode and the quartz ampoule inner tubal wall.In the case, discharge lamp can produce micro discharge (micro-discharge) phenomenon in this gap at interdischarge interval, causes reducing for second electrode life and the additionally consumption of electrical power.On the other hand, therefore bar-shaped second electrode of this kind needs extra fixed mechanism because can't be fixed in the quartz inner pipe inner surface voluntarily, causes the harmful effect of discharge lamp luminance nonuniformity or short circuit to avoid second electrode to slide in interior pipe.
In order to make the second electrode adherence in the inner surface of interior pipe, also there is prior art to utilize print process or steaming method, with metal coated such as gold, silver, aluminium, copper or nickel on the inner surface of the interior pipe of dielectric barrier discharge lamp pipe, forming second electrode, as the content that is disclosed in No. the 200123577th, the day disclosure special permission communique (Te Kaiping).But, the inner tube diameter little (for example being 5mm-15mm) of common discharge lamp, pipe range long again (for example being 300mm-1200mm), difficult print film or the vapor-deposited film that obtains the thickness homogeneous in this slender space.Simultaneously, print film or vapor-deposited film peel off easily, and when discharge lamp through after lighting a lamp for a long time, electrode is corroded easily.
United States Patent (USP) the 5th, 432 discloses in No. 398 and a kind ofly is wound into spiral helicine second electrode with metal wire.Also disclose another kind of in day disclosure special permission communique (Te Kaiping) 2002343306-A number by formed second electrode of wire netting.Yet, because this kind wire or the second netted electrode can't cover the inner surface of whole interior pipe fully, the inner surface of pipe in the light of some can penetrate when consequently discharging, and can't be reflexed to outside the outer tube by second electrode.In brief, this wire or netted second electrode be because of having the light reflecting effect, so adopt the luminous efficiency and the luminous intensity of dielectric barrier discharge lamp pipe of this kind electrode on the low side.
Disclose in No. the 392195th, day disclosure special permission communique (Te Kaiping) 8-96770 number or the Taiwan patent publication No. and a kind ofly be bent into second electrode of pipe shape slightly with metallic plate, this slightly pipe shape member have a breach in axial total length across it.Because the metallic plate in this patent only is bent into the semicircle tubulose or puts into pipe again near second electrode of the summary pipe shape in a week, so second electrode is close on the inner pipe wall of dielectric barrier discharge lamp pipe because of the not good elastic force of expanding outward of self that can't only lean on of elastic force.Therefore, when assembling second electrode, also need on axial total length, additionally install helical spring additional, so that second electrode is close on the inner tubal wall of dielectric barrier discharge lamp pipe across it.Because the inner tube diameter very little (about 5-15mm) and the pipe shaft of general dielectric barrier discharge lamp pipe grow (about 300-1200mm) again, so the degree of difficulty when setting up spring and can improve the installation of second electrode, the while also can increase the cost of manufacture of dielectric barrier discharge lamp pipe.
