Ubumnyama beIzikrini zokubonisa ze-LEDkuyinto evamile.Namuhla, ake sibheke izizathu ezimbalwa eziyinhloko zokuba mnyama kwawo.
1. I-sulfurization, i-chlorination, kanye ne-bromination
Ungqimba oluyisiliva olukubakaki olubonisa i-LED luzokhiqiza i-sulfide esiliva uma luhlangana negesi equkethe isibabule, futhi uma luhlangana ne-acidic nitrogen equkethe i-chlorine negesi ye-bromine, luzokhiqiza i-photosensitive silver halide, ezokwenza umthombo wokukhanya ukuze ube mnyama futhi wehluleke.Isibabule/i-chlorine/i-bromination yemithombo yokukhanya kungenzeka kuzo zonke izigaba zokukhiqiza, ukugcinwa, ukuguga, nokusetshenziswa kwemithombo yokukhanya ye-LED nezibani.Ngemva kokutholakala nesulfure/chlorine/bromination ngenxa yokuba mnyama komthombo wokukhanya, ikhasimende lidinga ukukhetha uhlelo oluthile lokususa isibabule ngokusekelwe esigabeni lapho kwenzeka khona isulfure/chlorine/bromination.Njengamanje, amaphrojekthi okuthola isibabule/i-chlorine/ibromine eyethulwe iJinjian ahlanganisa: isibabule sesibani/i-chlorine/ibromine (kuhlanganise nokwakhelwe ngaphakathiukunikezwa kwamandla kagesi), isibabule/i-chlorine/ibromine yesibani (ngaphandle kwamandla kagesi angaphandle), amandla kagesi sulphur/chlorine/bromine, insizakalo yesibabule/i-chlorine/bromine, ishabhu lokupakisha isibabule/i-chlorine/bromine, indawo yokusebenzela yokukhanyisa isulfure/i-chlorine/bromine, kanye ne-reflow soldering indawo yokusebenzela isulfure/chlorine/bromine.Ngenxa yokuthi amagesi aqukethe isulfure, i-chlorine, ne-bromine angangena ngaphakathi komthombo wokukhanya ngokusebenzisa izikhala ze-silicone noma kubakaki, i-Jinjian iphinde yethula uhlelo lokuhlola ukungangeni komoya ukuze liqhubeke lisize amakhasimende ukuthuthukisa izimfuneko zawo zezinto zomthombo wokukhanya.
2. I-oxidation
Isiliva siphendula kalula onomoya-mpilo ezindaweni ezishisayo nezinomswakama, sikhiqize i-silver oxide emnyama.Ngemva kokuqinisekisa ukuthi isizathu sokuba mnyama komthombo wokukhanya ukufakwa kwe-oxidation kwesendlalelo se-silver plating, u-Jin Jian uzophakamisa ukuthi ikhasimende liqhubeke nokuhlola ukucinana komoya emthonjeni wokukhanya nesibani ukuze kuqedwe indlela yokungena komswakama.
3. I-Carbonization
Ngokusekelwe kokuhlangenwe nakho, ukukhubazeka kwezinto ezibonakalayo ezinkulu eziyisithupha zemithombo yokukhanya ye-LED (ama-chips, abakaki, i-crystal glue eqinile, izintambo ezibophayo, impushana ye-fluorescent, neglue yokupakisha) kanye nokukhubazeka kwenqubo ezinqubweni ezintathu ezinkulu zokupakisha (ikristalu eliqinile, izintambo, kanye ne-gluing) konke kungaholela emazingeni okushisa aphezulu kakhulu emthonjeni wokukhanya, okubangela ubumnyama basendaweni noma buphelele kanye ne-carbonization yomthombo wokukhanya.Idizayini yokushabalalisa ukushisa engenangqondo yamalambu e-LED, ukuguquguquka okushisayo okuphansi kwezinto zokukhipha ukushisa, ukuklama kokuphakelwa kwamandla okungenangqondo, kanye nokukhubazeka okuningi kakhulu kwe-reflow soldering nakho kungabangela i-carbonization yomthombo wokukhanya.Ngakho-ke, lapho uJinjian eqinisekisa ngaphambilini ukuthi isizathu sokufiphala komthombo wokukhanya i-carbonization, izophakamisa ukuthi ikhasimende lilandele umthombo wokukhanya we-LED noma umzila wokuhlaziya ukuhluleka kwesibani, lihlukanise umthombo/isibani, futhi lihlonze umthombo wokukhubazeka noma ukumelana nokushisa okuphezulu.
4. Ukungahambisani kwamakhemikhali
Ukuba mnyama kwemithombo yokukhanya kwe-LED kungase futhi kubangelwe ukungcoliswa kwamakhemikhali, futhi lesi simo esiba mnyama sivame ukwenzeka kumalambu avaliwe anomoya omncane noma ongenawo nhlobo.
Uma sihlangabezana nesimo lapho isikrini sokubonisa se-LED siba mnyama, singaphenya izizathu ngasinye ngasinye futhi senze izinguquko.
