① Feem ntau cov iav neon teeb siv txias cathode glow paug (CCD). Vim tias tag nrho lub teeb ua kom tsis muaj cua sov thaum lub sijhawm ua haujlwm cathode txias, qhov ua tau zoo ntawm kev hloov hluav taws xob rau hauv lub teeb lub zog yog siab. Nws lub neej ntev ntev dua li cov teeb fluorescent zoo tib yam. Yog tias qhov zoo tau lees paub los ntawm cov ntaub ntawv thiab kev ua haujlwm rau kev teeb tsa, lub neej ntev ntawm cov iav neon tuaj yeem ncav cuag 20,000-30,000 teev. Cov qauv hauv zos hauv kuv lub tebchaws yuav tsum muaj tsawg kawg yog 10000 teev. Lwm qhov txiaj ntsig tseem ceeb ntawm cov teeb pom kev txias cathode yog tias tus naj npawb ntawm cov kev hloov pauv tau zoo tsis cuam tshuam rau lawv lub neej, ua rau lawv tshwj xeeb tshaj yog tsim rau cov teeb pom kev uas yuav tsum tau hloov mus tas li.
② Nws tso siab rau qhov zoo ions bombarding lub cathode, ua rau lub cathode emit lwm electrons los tswj cov paug. Yog li ntawd, qee qhov cathode muaj peev xwm poob yog yuav tsum tau muab lub zog rau kom nrawm cov ions zoo; lub cathode muaj peev xwm poob yog kwv yees li 100V-200V.
③ Txhawm rau kom muaj paug tawm hauv thaj av ib txwm muaj qhov ci ntsa iab thiab tiv thaiv cathode ntau dhau thaum lub sijhawm ua haujlwm, lub cathode yuav tsum muaj thaj tsam loj txaus. Otherwise, excessive current flow will lead to an excessively high cathode current density, increasing the cathode potential drop and resulting in abnormal glow discharge, exacerbating cathode sputtering and shortening the lamp's lifespan.
④ Qhov twg ua tau, lub iav neon teeb lub raj yuav tsum ntev li ntev tau nrog lub taub me me sab hauv kom ua kom muaj qhov sib npaug ntawm cov kab hluav taws xob zoo hauv tag nrho cov teeb hluav taws xob poob, yog li txhim kho luminous efficiency.
⑤ Txhawm rau kom muaj kev vam meej ntawm cov iav neon teeb lub raj thiab kev ua haujlwm ruaj khov ntawm cov hluav taws xob qis, lub siab -voltage transformer (feem ntau to - hom, tab sis vim nws qhov loj thiab siv hluav taws xob ntau, nws yuav maj mam hloov los ntawm hom hluav taws xob) yuav tsum tau nruab thiab ua kom zoo sib xws kom txuag tau tus nqi ntawm qhov project.
⑥ Cov iav neon teeb ua haujlwm ntawm qhov hloov pauv tam sim no, yog li ob lub electrodes hloov pauv li cathode thiab anode, thiab kev faib tawm ntawm thaj chaw ci ntsa iab kuj hloov mus ua ntu thiab kev coj ua. Vim qhov tsis pom kev tsis pom kev, lub ci ntsa iab zoo nkaus li npog tag nrho lub teeb lub raj, ua rau muaj txiaj ntsig zoo tshaj plaws luminous tshaj li thaum siv tam sim no. Yog li, cov ntaub ntawv thiab kev ua haujlwm ntawm ob lub electrodes yuav tsum ua kom zoo ib yam li qhov ua tau.
⑦ Vim tias iav neon teeb yog lub tshuab nqus hluav taws xob lub teeb, lub tshuab nqus tsev yuav tsum tau khaws cia thoob plaws tag nrho cov txheej txheem tsim khoom. Kev ua raws li kev ua raws li electro- lub tshuab nqus tsev yuav tsum muaj nyob rau hauv kev xaiv cov khoom thiab kev tsim khoom yog qhov tseem ceeb los xyuas kom meej qhov zoo.
