Description
One. technical field
Non internal electrode and no Hg highly efficient and long-life gas discharge surface light source disclosed by the invention belongs to field of illumination lamp technology, is specifically related to a kind of gas discharge surface light source that does not have interior electrode, no mercury, high-effect energy-conservation again, long-life, environmental protection.
Two. background technology
Glow discharge spot lamp or lamp also are the luminous fluorescent lamp of ionized gas, neon light, electricity-saving lamp etc., many advantages are arranged and extensively used by people than electric heating incandescent lamp bulb; But also because of there being deficiencies such as life-span weak point, mercury pollution that its application prospect is restricted.Trace sth. to its source, these shortcoming sources are for their structure and structure.No matter fluorescent lamp (hot cathode) class or neon light (cold cathode) class are because of its body poor sealing performance and built-in electrode make their useful life short; Make ionizer because of adding again, the mercurous grade of the light fixture of scrapping and contaminated environment with mercury (mercury); Also certainly lead to electric current and negative electrode loss effect between electrode because of electrode (built-in electrode) is set in the fluorescent tube, electrode is easily bombardment heating and consume also, and consuming electric power is many and not energy-conservation.To the structure of these class gaseous discharge lamps such as fluorescent lamp and neon light and the improvement of structure, be basic outlet and the effective way that improves this class gas discharge lamp behaviour.One of improvement is: change built-in electrode into external electrode, the structure of external electrode, Chinese patent early has: the patent No.: 92232188.4 are called " electrodeless high frequency sweep neon light ", thereafter the structure of electrode does not emerge many patents again in only just having, little because of its content and technology correlation of the present invention, needn't take the length narration.Glow discharge spot lamp or the lamp advanced configuration of not having an interior electrode is that people and society are known together thus.
Two of improvement is: no longer use the mercury (mercury) to make ionizer, promptly the ionized gas in glow discharge spot lamp or lamp is no mercury.In this respect, Chinese patent early has: the patent No.: 93104870.2 are called " cold cathode low-voltage mercury-free ultraviolet gas discharging lamp ", unusual be its to adopt purity nitrogen or nitrogen be discharge gas with inert gas, but it clearly discloses inert gas concrete component and proportioning.Adopt the Chinese patent of no mercury technology to also have: application number: 02126581.X (priority date: June 15 calendar year 2001, June 12 2002 applying date) name is called " low-pressure gaseous discharge lamp of anhydrous mercury filling gas ", the blanketing gas that this patent adopts has: fill gas and be sulphur, the selenium of the 4th main group silicon, germanium, tin, lead and sulfur family in the periodic table of elements, the compound of tellurium, cushion gas is helium, neon, argon, krypton, xenon, but regrettably this patent does not clearly disclose the concrete proportioning of use component of its buffer gas helium, neon, argon, krypton, xenon.Adopt the Chinese patent of no mercury technology many in addition, little because of its content and technology correlation of the present invention, needn't take length and quote.
About gas discharge surface light source, the Chinese patent of seeing has: the patent No.: 200420006645.8 are called " high efficiency plane fluorescent lamp source ", this area source has many different with area source of the present invention, electrode as it is interior electrode, but this area source is than good many of the area source that is made of side by side many pipes (line) light source.In recent years the various shortcoming of class gas discharge modulated structure such as fluorescent lamp and neon light and structure is still being carried out constantly research and improving, we the electricity of these light sources or lamp cause high-effect luminous aspect, electricity saving and energy saving aspect, the configuration aspects of area source shell and the performance and the secure context of external electrode all develop and improve, and succeeded in developing this non internal electrode and no Hg highly efficient and long-life gas discharge surface light source.Non internal electrode and no Hg highly efficient and long-life gas discharge surface light source of the present invention, be a kind of environmental protection, long-life, more energy-conservation new lighting, the light fixture that can be used for indoor and outdoor lighting, decoration, lamp box, advertisement, signboard, vehicle, the light fixture of special use or special purpose, LCD backlight aspects such as (backlights of LCD TV, notebook computer) has vast market prospect.
Three. summary of the invention
