Imiba yentlalo kunye nokusingqongileyo
Kwimveliso yeetshiphu ze-LED, i-asidi ye-inorganic, i-oxidants, i-ejenti eyinkimbinkimbi, i-hydrogen peroxide, izinyibilikisi eziphilayo kunye nezinye izinto zokucoca ezisetyenziswa kwinkqubo yokuvelisa i-substrate, kunye nesigaba segesi yentsimbi kunye negesi ye-ammonia esetyenziselwa ukukhula kwe-epitaxial, ziyityhefu. kunye nokungcolisa. Ezi zizinto eziqhelekileyo zeekhemikhali ezisetyenziswa ngokuqhelekileyo kwimveliso yeesekethe ezidibeneyo ze-semiconductor kunye namanye amashishini. Kwiinkampani ze-chip ze-LED ezikolu didi oluphezulu, iteknoloji yokucubungula kunye neenkqubo zabo zingqongqo kwaye zisebenza kakuhle, okwenza kube lula ukwenza unyango olungenabungozi.
Izixhobo zokulawula i-LED (ezaziwa ngokuba zizixhobo zamandla okuqhuba) azifani nezibane zemveli ze-fluorescent, izibane ze-halide zetsimbi, kunye nezinye ii-ballasts ze-elektroniki, kunye nobutyhefu kunye nongcoliseko oluveliswe kwinkqubo yokuvelisa izinto ezahlukeneyo zombane eziqhelekileyo zabathengi.
Igobolondo le-aluminium esetyenziswa ngokuqhelekileyo kwizibane ze-LED zifana ne-alluminiyam ye-alloy shell yemveli yokuvelisa, kunye netyhefu kunye nongcoliseko olwenziwa ngexesha lokwenziwa kwenkqubo yokwenziwa kweeplastiki okanye iigobolondo zentsimbi azinyuki kakhulu.
Ngamafutshane, akukho mfuneko yokukhathazeka malunga nemveliso yokukhanyisa i-semiconductor abantu abadibana nayo ngokuthe ngqo, kunye nemiba yokusingqongileyo ngexesha lenkqubo yokuvelisa.

Iinkxalabo zokhuseleko lomntu
1. Umbane ophantsi we-LED ukhuselekile kakhulu kwaye ulahlekisa uluntu
Uninzi lwabasebenzi bezobugcisa kumashishini banokuqonda okunzulu kunye nokungaphelelanga kokhuseleko lombane lweemveliso zokukhanyisa i-LED kunye nokuhanjiswa kwamandla okuqhuba, okukhokelela ekukhuselweni kombane kwabaninzi abayilwe kwaye baveliswe iimveliso zokukhanyisa i-LED ezixhomekeke ngokupheleleyo kukhuseleko lombane wokuqhuba. Nangona kunjalo, ukwahlulwa kombane kunye nokugqunyelelwa kwezinto ezininzi ezixhasa umbane wokuqhuba i-LED azifikeleli kwiimfuno eziqhelekileyo. Ukongeza, isixa esikhulu sonyuselo malunga nokhuseleko lwamandla ombane aphantsi we-LED unokulahlekisa abantu ukuba babambe rhoqo iimveliso, okukhokelela kumngcipheko omkhulu wokothuka kombane kuneemveliso zokukhanyisa zemveli abantu abazi ngokungaziyo ukuba amandla abo ombane aphezulu ayingozi kwaye bangaze babambe nje. .
2. Umba wengozi yokukhanya okuluhlaza kwe-LED
I-blue chip yohlobo lwe-LED emhlophe inombala ogxile kakhulu kwi-spectrum eyingozi kunezibane ze-fluorescent, kubandakanywa nezibane zokonga umbane, okukhokelela kwi-spectrum eyingozi ngokuphindwe kabini kunezibane ze-fluorescent. Ukongeza, indawo yokukhupha incinci kwaye ukukhanya kuphezulu, okwenza umonakalo wokukhanya okuluhlaza ubonakale ngakumbi kunezinye izibane. Nangona kunjalo, kwithiyori kunye novavanyo lwesiqinisekiso sokhuseleko lwemveliso yexesha elide, ekusebenzeni, ngaphantsi kwe-5% yezibane zedesika ezingqongqo ze-LED zidlula iimfuno zengozi ye-RG1. Ezi zibane kufuneka zibhalwe kuphela ngophawu "Musa ukujonga ngokuthe ngqo kumthombo wokukhanya ixesha elide" kwindawo ebonakalayo kwaye ibonise umgama okhuselekileyo wokukhumbuza abasebenzisi ukuba bahlangabezane neemfuno eziqhelekileyo. Ziyakwazi ukuthengiswa kwaye zisetyenziswe ngaphandle kweengxaki, ezikhuseleke kakhulu kunokuba zijonge ngokuthe ngqo ekukhanyeni kwelanga ixesha elifutshane. Kwaye kunye nokongezwa kwekhava yesanti, izibane ze-LED azikho iingxaki. Kwaye ayizizo ii-LED kuphela ezibeka umba wokhuseleko lwebhayoloji. Enyanisweni, ezinye iindawo zokukhanya zendabuko, ezifana nezibane ze-metal halide zangaphambili, zinokuba ne-UV eyingozi kakhulu kunye nobungozi obuhlaza okwesibhakabhaka.
3. Umba weStrobe
Kufuneka kuthiwe iimveliso zokukhanyisa ze-LED zinokuba yeyona nto incinci i-flicker ekhululekile kunye neyona nto izinzileyo ekukhanyeni okukhuphayo (ezifana nabaqhubi abaninzi be-DC ecocekileyo ehambelana nombane kwimarike). Kwaye iimveliso ezenziwe kakubi zinokuba ne-flicker enzima (ezifana nezo zingenawo umbane wokuqhuba, apho igridi yamandla e-AC inikezela ngokuthe ngqo amandla kumtya we-LED okanye i-COB-LED), kodwa oku akwahlukanga kakhulu kwingxaki ye-flicker yetyhubhu ethe tye. izibane ze-fluorescent ezine-inductive ballast. Oku akuxhomekeke kumthombo wokukhanya we-LED, kodwa kunikezelo lwamandla kunye nomthombo wamandla oqhubayo ohambelana nawo. Umgaqo ofanayo uyasebenza kwi-flicker yeemveliso zokukhanyisa ukukhanya kwendabuko.
