Description
The present invention is based on the 42nd proposition of Patent Law of the People's Republic of China detailed rules for the implementation, is that to be called " excited quasi-molecular lampbulb ", application number be dividing an application of 02155400.5 Chinese invention patent application for the name submitted on December 6th, 2002.
Technical field
The present invention relates to excited quasi-molecular lampbulb (excimer lamp), the junction surface of pipe and outer tube is because of the excited quasi-molecular lampbulb of ultraviolet ray deterioration in being specifically related to be used to prevent.
Background technology
Excited quasi-molecular lampbulb is a kind of by dielectric barrier layer discharge formation excimers, and utilizes from the dielectric barrier-layer discharge lamp of the light of excimers radiation.Can be used as photochemically reactive ultraviolet light source from the ultraviolet ray of excited quasi-molecular lampbulb radiation.
As shown in Figure 6, the dual pipe structure of pipe 1 and outer tube 2 arranged coaxial in excited quasi-molecular lampbulb adopts.The inner surface of interior pipe 1 is provided with an electrode, and the outer surface of outer tube 2 is provided with another electrode.Be filled with discharge rare gas in the discharge space 6 that between interior pipe 1 and outer tube 2, forms.By between two electrodes, applying high frequency voltage, the discharge space 6 beginning excimers discharges between interior pipe 1 and outer tube 2.From the excimers radiating light.Excited quasi-molecular lampbulb has existing Cooper-Hewitt lamp or the unexistent feature of high-tension arc light modulation.For example, but the emission center wavelength is the short UV light of 172nm.
Yet, the discharge gas leakage takes place in the lighting of lamp sometimes.If, then will not work soon, thereby shorten the life-span of lamp owing to lamp taking place to continue to make under the state that leaks to light lamp.Leakaging cause is at the junction surface 3 of interior pipe 1 and outer tube 2 crackle to take place.As shown in Figure 7, the 3 initial micro-cracks 7 that take place at the junction surface.This micro-crack 7 enlarges and becomes crackle, causes enclosing gas leakage.In addition, if crackle enlarges, then can cause the bulb breakage.Time before crackle takes place is under the flicker illuminating state about 600～700 hours.
The crackle genesis mechanism is as follows.Engaging by pipe 1 and outer tube 2 weldings etc. in making when making lamp, 3 residually have a small machining deformation at the junction surface.Cut off the molecule combination of glass by the high-energy ultraviolet ray that the discharge of dielectric barrier layer takes place, and make the glass deterioration.If the molecule of crushed element is in conjunction with being cut off, then distortional stress is concentrated, and makes molecule in conjunction with easier being cut off, and soon crackle will take place.
Open the spy and to have proposed in the flat 9-97597 communique a kind ofly to be used to prevent the solid ultraviolet ray in junction surface and the method for deterioration.This method can reduce the ultraviolet ray at the junction surface of the interior pipe that shines the dielectric barrier-layer discharge lamp and outer tube, and can prevent that the junction surface from crackle taking place.As shown in Figure 8, be provided with ultraviolet direct projection at the junction surface 3 of interior pipe 1 and outer tube 2 and prevent parts 8.No matter be the metallic film that oxidation titanium film, barium, cerium oxide, zinc oxide etc. are set, still in interior pipe 1 and outer tube 2, wrinkle mutually be set, glass fibre cotton perhaps is set between junction surface and discharge space, all can be used as direct projection and prevent parts 8.And, can be at the junction surface 3 the blast pipe afterbody be set, and can metal protective film be set at the inner face of blast pipe afterbody.
But above-mentioned existing direct projection prevents that from there is a problem in parts is to prevent fully that crackle from taking place.It is the reasons are as follows.As shown in Figure 9, the ultraviolet ray that produces at discharge space is owing to the optical fiber effect concentrates on junction surface 3.In order to make light total reflection enter into the inside of fiber optics, make light total reflection arrive the interior pipe 1 of dual spot bubble and the inside of outer tube 2, and 3 concentrate at the junction surface.Ultraviolet ray after concentrating becomes fragile junction surface 3, and produces micro-crack.Existing direct projection prevents that parts from can not be prevented the ultraviolet ray at the glass internal communication.And existing direct projection prevents that the micro-crack that parts also can not prevent from enlarging.
In addition, by in discharge space, sneaking into discharge with the material beyond the gas or apply, following evils can take place, for example, owing to coating material produces impure gas, owing to discharge descends with the brightness that the pollution of gas etc. causes, uneven luminance, the breakage of the lamps that cause owing to the thermal coefficient of expansion difference etc.And,, the intensity decreases of bulb or the factor of distortion formation are increased owing to form wrinkle mutually.
Summary of the invention
The objective of the invention is: solve above-mentioned existing issue, the generation of the micro-crack that causes because of the ultraviolet ray at the glass internal communication is suppressed, the micro-crack that prevents simultaneously enlarges, and prolongs the life-span of excited quasi-molecular lampbulb.
In order to solve above-mentioned problem, in the present invention, at following excited quasi-molecular lampbulb, that is: in the outer tube of the dual pipe structure that engages and seal and form with the end of the outer tube of interior pipe arranged coaxial and interior pipe and the space between the interior pipe, fill discharge rare gas, on the body of outer tube between effective illuminating part and the junction surface and interior pipe, be provided for absorbing or the light shielding part of scatters ultraviolet.By adopting this formation, can the ultraviolet ray that cause owing to the optical fiber effect be suppressed to the concentrated of junction surface, and can prevent that micro-crack from producing.
And, be coated with curing agent at the junction surface of excited quasi-molecular lampbulb, by adopting this formation, mechanical strength can be improved, and the diffusion of micro-crack can be suppressed.
