Umgaqo we-Semiconductor LED kufuneka uqondwe

I-diode ekhanyayo-emitting i-Inumgarnet (i-CE3: i-yag) i-crystal igaywe ibe ngumgubo kwaye ixutywe kunye ne-adhesive dense. Xa i-chip ye-LED ikhupha ukukhanya okuluhlaza okwesibhakabhaka, enye i-Blu-ray iya kuguqulwa yile kristale kunye noluhlu olubanzi lwee-spectrals (malunga ne-580nm kumbindi we-spectrum). (Enyanisweni, i-YAG ye-crystal eyodwa exutywe nge-CE ithathwa njenge-flicker kune-phosphorus.) Ngenxa yokuba ukukhanya okuphuzi kuya kuvuselela i-receptors ebomvu neluhlaza emehlweni e-ze, ukukhanya okuluhlaza okwesibhakabhaka kwe-LED ngokwayo kwenza kubonakale njengokukhanya okumhlophe. Kwaye umbala wayo udla ngokubizwa ngokuba “Ukukhanya kwenyanga kumhlophe ”. Le ndlela yokwenza ukukhanya okumhlophe kwe-LED iphuhliswa yi-Nichiacorporation kwaye yaqala ukuvelisa ukukhanya okumhlophe kwe-LED ngo-1996. Ukuba ufuna ukulungelelanisa umbala wokukhanya okumthubi okumthubi, ungasebenzisa enye into enqabileyo yomhlaba okanye ukutshintsha (CE) ebandakanywe kwi-CE3: yag, kwaye nendlela yokutshintsha iinxalenye okanye yonke i-aluminium kwi-YAG ukuyenza. Ngokusekelwe kwiimpawu ze-spectrum yayo, izinto ezibomvu kunye neziluhlaza zikhangeleka ngaphantsi kwe-wide-spectrum light source phantsi kwesi sityhilelo se-LED. Ukongezelela, ngenxa yokuguqulwa kweemeko zokuvelisa, ukushisa kombala walo mveliso ogqityiweyo awufani, ukusuka kwi-yellow yellow ukuya kwi-blue blue. Ngoko ke, kwinkqubo yokuvelisa. Enye indlela emhlophe-ekhanyayo ye-LED ifana nesibane se-fluorescent. I-LED ekhupha phantse ukukhanya kwe-ultraviolet iya kupeyintwa ngemixube emibini ye-phosphorus, enye ibomvu kunye nokukhanya okuluhlaza okwesibhakabhaka, kunye nokukhanya okuluhlaza. Ubhedu kunye ne-aluminium kunye ne-zinc sulfide (ZNS). Nangona kunjalo, ngenxa yokuba imitha ye-ultraviolet inokwenza i-epoxy resin iqhekeke kwaye yonakale kwizinto ezincamathelayo, imveliso inzima ngakumbi kwaye ixesha lokuphila lifutshane. Xa kuthelekiswa nendlela yokuqala, inokusebenza okuphantsi kwaye ivelisa ubushushu obungaphezulu (kuba i-STOKESSHIFT yangaphambili ine-yangaphambili enkulu), kodwa inzuzo kukuba iimpawu ze-spectrum zingcono. Ngenxa yokuba amandla e-LED okukhanya kwe-UV aphezulu, nangona ukusebenza kakuhle kuphantsi, ukukhanya kuphuma kuyafana. Indlela yamva nje yokwenza ukukhanya okumhlophe kwe-LED ayisebenzisi umzimba wokukhanya we-phosphorus kwakhona. Indlela entsha yokukhulisa i-zinc kwi-zinc -zinc (ZNSE) substrate. Xa ilayitiwe, indawo yayo esebenzayo iya kukhupha ukukhanya okuluhlaza kwaye i-substrate iya kuba tyheli, kwaye iya kuba kukukhanya okumhlophe ukuxuba.
