Ukusebenza kwezinga lokushisa okuphezulu kunamuphi umphumela kusibonisi esiholayo?Ngokusetshenziswa okwandayo kwezikrini zokubonisa ze-LED namuhla, ukuze kwandiswe izinzuzo zesikrini sokubonisa, abasebenzisi kufanele babe nokuqonda okuthile kokunakekelwa kwesikrini se-LED.Kungakhathaliseki ukuthi isibonisi se-LED sasendlini noma isibonisi se-LED sangaphandle, ukushisa kuzokhiqizwa ngesikhathi sokusebenza, futhi ukushisa okukhiqizwa kuzobangela izinga lokushisa lesibonisi se-LED ukuthi likhuphuke.Kodwa, ingabe uyazi ukuthi ukusebenza kwezinga lokushisa eliphezulu kunamuphi umphumela kusibonisi esiholayo?Ake sikhulume ngomkhiqizi wesibonisi we-Shenzhen LED Tuosheng Optoelectronics.

Ngaphansi kwezimo ezijwayelekile, izibonisi ze-LED zasendlini zikhiqiza ukushisa okuncane ngenxa yokukhanya okuphansi futhi zingahlakazeka ngokwemvelo.Kodwa-ke, isikrini se-LED esingaphandle sikhiqiza ukushisa okukhulu ngenxa yokukhanya kwaso okuphezulu, futhi sidinga ukuchithwa yi-air conditioner noma i-axial fan.Njengoba isibonisi se-LED siwumkhiqizo we-elekthronikhi, ukunyuka kwezinga lokushisa kuzothinta ukuncishiswa kokukhanya kobuhlalu besibani sesibonisi se-LED, ngaleyo ndlela kunciphise ukusebenza kahle komshayeli we-IC futhi kufinyeze impilo yesevisi yesibonisi se-LED.

1. Isibonisi se-LED sokuhluleka kwesifunda esivulekile: izinga lokushisa elisebenzayo lesibonisi se-LED lidlula izinga lokushisa lomthwalo we-chip, elizonciphisa ngokushesha ukusebenza kahle okukhanyayo kwesikrini se-elekthronikhi ye-LED, kubangele ukuncishiswa kokukhanya okusobala futhi kubangele umonakalo;isibonisi se-LED senziwa ngokuyinhloko nge-epoxy resin esobala .Ekuphakhenisweni, uma izinga lokushisa lenhlukana ndlela lidlula izinga lokushisa lesigaba esiqinile (imvamisa engu-125°C), impahla yokupakisha izophenduka ibe irabha futhi i-coefficient yokunweba okushisayo izokhuphuka kakhulu, okuholela ekwehlulekeni kwesekethe evulekile yesibonisi se-LED.Izinga lokushisa elidlulele lizothinta ukubola kokukhanya kwesibonisi se-LED.Impilo yesibonisi se-LED ibonakala ngokuncipha kwayo kokukhanya, okungukuthi, ukukhanya kuzoba ngaphansi futhi kube phansi ngokuhamba kwesikhathi kuze kucime.Izinga lokushisa eliphezulu liyimbangela eyinhloko yokuncishiswa kokukhanya kwesibonisi se-LED, futhi kuzofinyeza impilo yesibonisi se-LED.Ukunciphisa ukukhanya kwemikhiqizo ehlukene yezibonisi ze-LED kuhlukile, ngokuvamile abakhiqizi be-Shenzhen LED banikeza isethi yamajika ajwayelekile okunciphisa ukukhanya.Ukuncishiswa kokushintshashintsha okukhanyayo kwesikrini se-elekthronikhi ye-LED okubangelwa izinga lokushisa eliphezulu akunakuhlehliswa.

Ukukhanya okukhanyayo ngaphambi kokunciphisa ukukhanya okungenakuhlehliswa kwesibonisi se-LED kubizwa ngokuthi "ukukhanya okukhanyayo kokuqala" kwesikrini se-electronic LED.

2. Ukwenyuka kwezinga lokushisa kuzonciphisa ukusebenza kahle okukhanyayo kwesibonisi se-LED: izinga lokushisa liyakhula, ukugxila kwama-electron nezimbobo kuyanda, igebe lebhande liyancipha, futhi ukuhamba kwe-electron kuncipha;izinga lokushisa likhuphuka, ama-electron emthonjeni ongase abe khona azonciphisa izimbobo Ukukwazi ukuhlanganiswa kabusha kwemisebe kuholela ekuhlanganiseni okungenayo imisebe (ukushisa), ngaleyo ndlela kunciphise ukusebenza kahle kwe-quantum yangaphakathi yesibonisi se-LED;izinga lokushisa elikhulayo libangela ukuphakama okuluhlaza okwesibhakabhaka kwe-chip ukuya ohlangothini olude lwamagagasi, okubangela ubude beza obuphumayo be-chip buhlangane nephosphor.Ukungafani kwe-excitation wavelength kuzophinda kubangele ukusebenza kahle kokukhipha ukukhanya kwangaphandle kwesibonisi esimhlophe se-LED ukuthi kwehle.Isikrini: Njengoba izinga lokushisa likhuphuka, ukusebenza kahle kwe-quantum kwe-phosphor kuncipha, inani lokukhanya elikhishwayo liyehla, kanye nokusebenza kahle kokukhipha ukukhanya kwangaphandle kwesibonisi se-LED kuncipha.Ukusebenza kwejeli ye-silica kuthinteka kakhulu izinga lokushisa elizungezile.Njengoba izinga lokushisa likhuphuka, ingcindezi yokushisa ngaphakathi kwejeli ye-silica iyanda, okwenza inkomba ye-refractive yejeli ye-silica yehle, ngaleyo ndlela kuthinte ukusebenza kahle kokukhanya kwesibonisi se-LED.
