Baki naLED nuni fuskaal'amari ne na kowa.A yau, bari mu dubi manyan dalilai da yawa na baƙar fata.
1. Sulfurization, chlorination, da bromination
Layin plating na azurfa da ke jikin bangon nuni na LED zai samar da sulfide na azurfa idan ya hadu da iskar gas mai dauke da sulfur, kuma idan ya hadu da sinadarin chlorine mai dauke da sinadarin nitrogen da iskar bromine, zai haifar da halide na azurfa na photosensitive, wanda zai haifar da hadari. tushen hasken ya juya baki ya kasa.Sulfur / chlorine / bromination na tushen haske na iya faruwa a kowane mataki na samarwa, ajiya, tsufa, da kuma amfani da tushen hasken LED da fitilu.Bayan an gano shi tare da sulfur / chlorine / bromination saboda baƙar fata na tushen haske, abokin ciniki yana buƙatar zaɓar takamaiman shirin kawar da sulfur bisa matakin da sulfur / chlorine / bromination ke faruwa.A halin yanzu, ayyukan gano sulfur / chlorine / bromine da Jinjian ya ƙaddamar sun haɗa da: sulfur sulfur / chlorine / bromine (ciki har da samar da wutar lantarki), fitilar sulfur / chlorine / bromine (ban da wutar lantarki na waje), sulfur sulfur / chlorine / bromine, karin kayan sulfur / chlorine / bromine, marufi bita sulfur / chlorine / bromine, hasken wuta sulfur / chlorine / bromine, da reflow soldering bitar sulfur / chlorine / bromine.Saboda iskar gas da ke dauke da sulfur, chlorine, da bromine na iya kutsawa cikin cikin hasken hasken ta hanyar gibi a cikin siliki ko braket, Jinjian ya kuma kaddamar da wani shiri na duba iska don kara taimakawa abokan ciniki wajen inganta bukatunsu na kayayyakin samar da hasken.
2. Oxidation
Azurfa cikin sauƙi yana amsawa tare da iskar oxygen a cikin yanayin zafi da zafi, yana samar da baƙin ƙarfe oxide na azurfa.Bayan tabbatar da cewa dalilin baƙar fata na tushen hasken shine iskar oxygenation na Layer plating na azurfa, Jin Jian zai ba da shawarar cewa abokin ciniki ya ci gaba da gudanar da bincike na iska a kan tushen hasken da fitila don kawar da hanyar shigar danshi.
3. Carbonization
Dangane da gogewa, lahani na kayan abu a cikin manyan albarkatun ƙasa guda shida na tushen hasken LED (kwakwalwa, brackets, m crystal manne, bonding wayoyi, kyalli foda, da marufi manne) da kuma aiwatar lahani a cikin uku manyan marufi tafiyar matakai (m crystal, wiring, da gluing) duk na iya haifar da matsanancin zafi a cikin hasken haske, haifar da baƙin ciki na gida ko gabaɗaya da carbonization na tushen hasken.Zane mara ma'ana mara ma'ana na fitilun LED, ƙarancin ƙarancin zafin jiki na kayan ɓarkewar zafi, ƙirar samar da wutar lantarki mara ma'ana, da lahanin sake kwararar da yawa kuma na iya haifar da carbonization na tushen haske.Saboda haka, lokacin da Jinjian da farko ya tabbatar da cewa dalilin baƙar fata na tushen hasken shine carbonization, zai ba da shawarar cewa abokin ciniki ya bi hanyar binciken hasken LED ko gazawar fitilar, ya rarraba tushen / fitilar, da gano tushen lahani ko high thermal juriya.
4. Rashin daidaituwar sinadarai
Baƙin tushen hasken LED shima yana iya haifar da gurɓacewar sinadarai, kuma wannan al'amari mai baƙar fata yakan faru a cikin fitilun da aka rufe tare da ɗan iska ko kaɗan.
Lokacin da muka haɗu da yanayin da allon nuni na LED ya zama baki, zamu iya bincika dalilan daya bayan daya kuma muyi gyare-gyare.
