Indlela yokupakisha yemithombo yokukhanya ye-UV LED ihlukile kweminye imikhiqizo ye-LED, ikakhulukazi ngoba inikezela ngezinto nezidingo ezahlukahlukene.Iningi lemikhiqizo ye-LED yokukhanyisa noma yokubonisa yakhelwe ukusiza iso lomuntu, ngakho-ke uma ucabangela amandla okukhanya, udinga futhi ukucabangela ikhono leso lomuntu lokumelana nokukhanya okunamandla.Nokho,Izibani ze-UV LED zokuphulukisaazilisebenzisi iso lomuntu, ngakho-ke zihlose ukuqina kokukhanya okuphezulu kanye nokuminyana kwamandla.
Inqubo yokupakisha ye-SMT
Njengamanje, ubuhlalu besibani se-UV obujwayelekile kakhulu emakethe bupakishwa kusetshenziswa inqubo ye-SMT.Inqubo ye-SMT ibandakanya ukukhweza i-chip ye-LED kusithwali, ngokuvamile esibizwa ngokuthi ubakaki we-LED.Izithwali ze-LED ikakhulukazi zinemisebenzi ye-thermal ne-electrical conductive futhi zinikeza ukuvikeleka kwama-chips e-LED.Abanye futhi kufanele basekele amalensi e-LED.Imboni ihlukanise amamodeli amaningi alolu hlobo lobuhlalu besibani ngokuya ngemininingwane ehlukene namamodeli ama-chips nabakaki.Inzuzo yale ndlela yokupakisha ukuthi izimboni zokupakisha zingakhiqiza ngezinga elikhulu, okunciphisa kakhulu izindleko zokukhiqiza.Ngenxa yalokho, ngaphezu kwe-95% yezibani ze-UV embonini ye-LED okwamanje zisebenzisa le nqubo yokupakisha.Abakhiqizi abadingi izidingo zobuchwepheshe ezeqile futhi bangakhiqiza izibani ezihlukahlukene ezijwayelekile kanye nemikhiqizo yesicelo.
Inqubo yokupakisha ye-COB
Uma kuqhathaniswa ne-SMT, enye indlela yokupakisha ukupakishwa kwe-COB.Emaphaketheni e-COB, i-chip ye-LED ihlanganiswe ngqo ku-substrate.Eqinisweni, le ndlela yokupakisha iyisixazululo sokuqala sobuchwepheshe bokupakisha.Lapho ama-chips e-LED eqala ukwakhiwa, onjiniyela bamukela le ndlela yokupakisha.
Ngokuqonda komkhakha, umthombo we-UV LED ulandele ukuminyana kwamandla aphezulu namandla aphezulu optical, afaneleka kakhulu inqubo yokupakisha ye-COB.Ngokwetiyori, inqubo yokupakisha ye-COB ingakhulisa ukupakishwa kwamahhala endaweni ngayinye yeyunithi ye-substrate, ngaleyo ndlela kuzuzwe ukuminyana kwamandla okuphezulu kwenani elifanayo lama-chips nendawo ekhipha ukukhanya.
Ngaphezu kwalokho, iphakheji ye-COB nayo inezinzuzo ezisobala ekulahlekeni kokushisa, ama-chips e-LED ngokuvamile asebenzisa indlela eyodwa kuphela yokuqhuba ukushisa ukuze adlulise ukushisa, kanye ne-hot conduction medium encane esetshenziswa enqubweni yokushisa ukushisa, kuya phezulu ukusebenza kahle kwephakheji ye-heater conduction.COB inqubo, ngoba i-chip ihlanganiswe ngokuqondile ku-substrate, uma iqhathaniswa nendlela yokupakisha ye-SMT, i-chip eya kusinki yokushisa phakathi kokunciphisa izinhlobo ezimbili ze-heat conduction medium, okuthuthukise kakhulu ukusebenza nokuzinza kwemikhiqizo yomthombo wokukhanya ophuzile.ukusebenza nokuzinza kwemikhiqizo yomthombo wokukhanya.Ngakho-ke, emkhakheni wezimboni wezinhlelo ezinamandla kakhulu ze-UV LED, ukusetshenziswa komthombo wokukhanya wokupakisha we-COB kuyisinqumo esingcono kakhulu.
Kafushane, ngokuthuthukisa ukuzinza kokukhipha amandla kweIsistimu yokwelapha ye-UV ye-LED, ukufanisa ubude bamaza obufanele, ukulawula isikhathi namandla okukhipha imisebe, umthamo ofanele wemisebe ye-UV, ukulawula izimo zemvelo elaphayo, kanye nokulawula ikhwalithi nokuhlola, ikhwalithi yokwelapha yamayinki e-UV ingaqinisekiswa ngempumelelo.Lokhu kuzothuthukisa ukusebenza kahle kokukhiqiza, kunciphise amanani okunqatshelwa, futhi kuqinisekise ukuqina kwekhwalithi yomkhiqizo.
