Ukuthuthukiswa kwe-Light-Curing Resin embonini yokupakishwa kwezintambo ze-LED
Emikhakheni yokukhanyisa okuhlakaniphile kanye nezintambo zokukhanya zokuhlobisa, inguquko yezobuchwepheshe eholwa ama-resin akhanyisa ukukhanya ichaza kabusha iphakheji yama-chips e-LED. Lokhu okusha akugcini nje ngokwandisa ukusebenza kahle kokukhiqiza, kodwa futhi kukhombisa izinzuzo ezinhle kakhulu ekongeni amandla kanye nokuvikelwa kwemvelo.
Lapho izintambo ze-LED ziba zivamile ekukhanyeni okuhlobisa, ekukhanyeni kwendawo, nasezinhlelweni zokukhanyisa ezihlakaniphile, imakethe idinga ubuchwepheshe obusha bokupakisha. Izinto zokulungisa ukushisa zendabuko ziye zaveza kancane kancane imikhawulo efana nesivinini sokupholisa esihamba kancane, ukusetshenziswa kwamandla amaningi, kanye nokusebenza kahle okuphansi.
Manje, impumelelo yakamuva kubuchwepheshe be-resin yokwelapha ukukhanya—ikakhulukazi, ukusetshenziswa kwe-UV kanye namakhemikhali okupheka aphilisa ukukhanya abonakalayo, kuletha izixazululo ezintsha embonini yonke.
Ukuthuthuka Kobuchwepheshe: Kusukela Kuthiyori Kuya Ekusetshenzisweni
Ama-resin aphilisa ukukhanya angaqina ngemizuzwana embalwa ngaphansi kokukhanya kwe-ultraviolet noma okubonakalayo. Izingxenye zawo eziyinhloko zifaka phakathi ama-resin e-acrylate, ama-monomer asabelayo, ama-photoinitiators, kanye nezinye izithasiselo ezahlukahlukene. Uma evezwa ekukhanyeni kwamaza athile, ama-photoinitiators akhiqiza ama-free radicals noma ama-cation asebenzayo abangela ukusabela okuxhumanisayo phakathi kwama-monomer nama-resin, akha ungqimba oluqinile lokuvikela.
Le ndlela yokwelapha ifaneleka kakhulu ekufakweni kwezintambo ze-LED—njengoba ama-chips e-LED ngokwawo angasebenza njengomthombo wokukhanya wokuziphilisa, okwenza kube lula ukuzifihla.
Ukubhekana Nezinselele Zemboni
Izindawo ezihlukile zokusetshenziswa kwezintambo ze-LED ziletha izinselele eziningi zokupakisha: izinhlelo zokusebenza zangaphandle zidinga ukumelana nomswakama, ukushintshashintsha kwezinga lokushisa, kanye nokuguga kwe-UV; izintambo eziyinkimbinkimbi zidinga izinto ezinokuguquguquka okuhle kanye nokuvuleka; kanye nokuthambekela kokwenza izinto zibe zincane kudinga izinto ezigcwalisa ngokugcwele izikhala ezincane ngaphandle kokuphazamisa ukusebenza kokukhanya.
Ukupakishwa kwe-resin ye-epoxy yendabuko, okunezinkinga ezifana nokuphola kancane, ukusetshenziswa kwamandla aphezulu, kanye nokuthambekela kokuphuzi, akusakwazi ukuhlangabezana nezidingo zezintambo ze-LED zesimanje zokukhiqiza kahle kakhulu kanye nokuthembeka kwesikhathi eside.
Inani Elisebenzayo Lamakhemikhali Okulungisa Ukukhanya
Ama-potting compounds athuthukisiwe acwebezela ukukhanya ngokuvamile aqukethe i-acrylate resin (izingxenye ezingu-40-80), i-reactive monomer (izingxenye ezingu-20-40), i-photoinitiator (izingxenye ezingu-1-8), kanye nezithasiselo (izingxenye ezingu-1-3). Ukwakheka okulungiselelwe kuvumela ukuthi izinto ziqine ngokuphelele ngemizuzwana engu-2-10 kuphela ngaphansi kokukhanya kwe-LED okunamandla aphezulu, okuthuthukisa kakhulu ukusebenza kahle kokukhiqiza.
Isibonelo, i-epoxy acrylate 61003A eguquliwe, eyathuthukiswa yi-Ever Ray. Lo mkhiqizo unikeza ububanzi be-viscosity obungu-8,000–18,000 (okwenza ufaneleke ukwakheka kwe-dome), isivinini sokuphendula okusheshayo, ukuqina okuhle kakhulu, kanye nezakhiwo ezinhle kakhulu zokulwa nokuphuzi.
Izinzuzo Zobuchwepheshe Ezivelele
Ama-resin aphilisa ukukhanya anikeza amandla amaningi ezinhlelweni zokufaka izintambo ze-LED:
Ukusebenza kahle kwamandla: Inqubo yokwelapha ukukhanya inganciphisa ukusetshenziswa kukagesi ngo-20-80%, okwenza kube lula ukwelapha ngesivinini esikhulu futhi kwandise kakhulu amandla okukhiqiza kubakhiqizi.
Ubungane nemvelo: Iningi lamakhemikhali ebhodweni anamuhla aphilisa ukukhanya awanazo izinyibilikisi nama-isocyanate, anokuqukethwe okuphansi kakhulu kwe-volatible organic compound (VOC).
Ukusebenza: Isendlalelo se-encapsulation esilungisiwe sinikeza ukuhanjiswa kokukhanya okuphezulu (>99% ku-spectrum ebonakalayo), ukumelana ne-UV isikhathi eside, kanye nokuvikelwa okuhle kakhulu kwemishini kanye nokukhululeka ekucindezelekeni. Njengamanje, izinhlobo ze-potting zihlukaniswe kakhulu zibe ezicacile, ezicacile kancane, kanye nezingabonakali.
Amathemba Emakethe Ebanzi
Ukusetshenziswa kwama-resin akhanyisa ukukhanya ensimini ye-LED kuyaqhubeka nokukhula. Kusukela ezibanini ezilula zezinkomba kuya kubuchwepheshe banamuhla bokubonisa i-Mini LED kanye ne-Micro LED, izidingo zezinto zokufaka i-capsulation zikhula njalo.
Emkhakheni wezintambo ze-LED, ama-resin akhanyisa ukukhanya awanikeli ukuvikelwa okusebenzayo kwe-chip kodwa futhi athuthukisa ukusebenza kahle kokukhipha ukukhanya, athuthukise ukuphuma kwe-LED, futhi andise impilo yesevisi. Njengoba kuqhubeka ukwanda kwemakethe yokukhanyisa okuhlakaniphile kanye nezintambo zokuhlobisa, amathuba obuchwepheshe bokumboza ukukhanya abukeka ethembisa kakhulu.
Idatha yemboni ikhombisa ukuthi imakethe yezinto zokupakisha ze-LED ikhula ngesilinganiso sonyaka esingama-10%, kanti ubuchwepheshe bokuphulukisa ukukhanya bungenye yezingxenye ezikhula ngokushesha. Lobu buchwepheshe abugcini nje ngokuthuthukisa ukusebenza kahle kokukhiqiza kodwa futhi buthuthukisa kakhulu ikhwalithi yomkhiqizo kanye nokuthembeka, buhlinzeka ngokusekelwa okuqinile kwentuthuko esimeme yemboni yokukhanyisa ye-LED.
