Yintoni impembelelo yokusebenza kobushushu obuphezulu kwisiboniso esikhokelwayo?Ngokusetyenziswa okukhulayo kwezikrini zokubonisa i-LED namhlanje, ukwenzela ukwandisa inzuzo yesikrini sokubonisa, abasebenzisi kufuneka babe nokuqonda okuthile kokugcinwa kwesikrini se-LED.Ingaba umboniso we-LED wangaphakathi okanye umboniso we-LED wangaphandle, ubushushu buya kuveliswa ngexesha lokusebenza, kwaye ubushushu obuvelisiweyo buza kubangela ukuba ubushushu bomboniso we-LED bunyuke.Kodwa, ngaba uyazi ukuba yintoni umphumo owenziweyo ekusebenzeni kobushushu obuphezulu kwisibonisi esikhokelwayo?Makhe sithethe nge-Shenzhen LED umenzi wokubonisa iTuosheng Optoelectronics.

Ngaphantsi kweemeko eziqhelekileyo, iziboniso ze-LED zangaphakathi zivelisa ubushushu obuncinci ngenxa yokukhanya okuphantsi kwaye zinokuchithwa ngokwemvelo.Nangona kunjalo, isikrini sokubonisa i-LED sangaphandle sivelisa ubushushu obuninzi ngenxa yokukhanya kwayo okuphezulu, kwaye kufuneka ichithwe yi-air conditioner okanye i-axial fan.Ekubeni umboniso we-LED yimveliso ye-elektroniki, ukunyuka kweqondo lokushisa kuya kuchaphazela ukukhanya kokukhanya kwesibane se-LED, ngaloo ndlela kuncitshiswe ukusebenza kakuhle komqhubi we-IC kunye nokunciphisa ubomi benkonzo yesiboniso se-LED.

1. Isiboniso se-LED sokungaphumeleli kwesiphaluka esivulekileyo: ubushushu obusebenzayo bomboniso we-LED budlula ubushushu bomthwalo we-chip, oya kunciphisa ngokukhawuleza ukusebenza okukhanyayo kwesikrini se-elektroniki se-LED, kubangele ukukhanya okucacileyo kunye nokubangela umonakalo;Umboniso we-LED wenziwa ikakhulu nge-epoxy resin ecacileyo.Ukupakisha, ukuba ubushushu be-junction budlula ubushushu besigaba esiqinileyo (ngokuqhelekileyo i-125 ° C), izinto zokupakisha ziya kujika zibe yirubha kwaye i-coefficient yokwandiswa kwe-thermal iya kunyuka ngokukhawuleza, okubangelwa ukungaphumeleli kwesiphaluka esivulekileyo somboniso we-LED.Ukushisa okugqithisileyo kuya kuchaphazela ukubola kokukhanya kwesiboniso se-LED.Ubomi bomboniso we-LED bubonakaliswa kukuthomalalisa ukukhanya, oko kukuthi, ukukhanya kuya kuba sezantsi kwaye kube sezantsi ngokuhamba kwexesha de kuphume.Ubushushu obuphezulu yeyona nto ibangela ukuthomalaliswa kokukhanya kwesibonisi se-LED, kwaye kuya kunciphisa ubomi bomboniso we-LED.Ukunciphisa ukukhanya kweempawu ezahlukeneyo zokubonisa i-LED kuyahluka, ngokuqhelekileyo abavelisi be-LED be-Shenzhen baya kunika iiseti zokunciphisa ukukhanya okuqhelekileyo.Ukuthotywa kokukhanya okukhanyayo kwesikrini se-elektroniki se-LED okubangelwa kubushushu obuphezulu akunakuguqulwa.

Ukukhanya okukhanyayo phambi kokuthotywa kokukhanya okungenakuguqulwa kwesiboniso se-LED kubizwa ngokuba "yi-luminous flux yokuqala" yesikrini se-elektroniki se-LED.

2. Ukunyusa izinga lokushisa kuya kunciphisa ukusebenza okukhanyayo komboniso we-LED: ukunyuka kweqondo lokushisa, ukuxinwa kwee-electron kunye nezimbobo zanda, i-gap band iyancipha, kwaye ukuhamba kwe-electron kunciphisa;ukwanda kweqondo lokushisa, ii-electron kwindawo enokubakho iya kunciphisa imingxuma Ukukwazi ukuphinda kufakwe kwi-radiation kukhokelela ekubuyiselweni kwe-radiative (ukufudumeza), ngaloo ndlela kuncitshiswe ukusebenza kakuhle kwe-quantum yangaphakathi yesiboniso se-LED;ukwanda kweqondo lobushushu kubangela ukuba incopho eluhlaza yetshiphu ihambe iye kwicala lamaza amaza, ibangela ukukhutshwa kwamaza e-chip ukuxubana nephosphor.Ukungahambelani kobude obuvuselelayo kuya kubangela ukuba ukusebenza kokukhanya kwangaphandle kwesiboniso esimhlophe se-LED kwehle.Isikrini: Njengoko iqondo lokushisa liphakama, ukusebenza kakuhle kwe-quantum ye-phosphor kuncipha, umlinganiselo wokukhanya okhutshwayo uyancipha, kunye nokusebenza kokukhanya kwangaphandle kokukhanya kwe-LED kuyancipha.Ukusebenza kwejeli ye-silica kuchaphazeleka ngakumbi bubushushu be-ambient.Njengoko iqondo lokushisa linyuka, uxinzelelo lwe-thermal ngaphakathi kwejeli ye-silica luyanda, lubangela ukuba isalathisi esihlaziyiweyo se-silica gel sinciphe, ngaloo ndlela sichaphazela ukukhanya komboniso we-LED.
