Ngaphambi kokuba kuhanjiswe, isibane sesitalato se-LED siya kuhlolwa zonke iintlobo zovavanyo. Ngoko ke zeziphi iimveliso eziza kuhlolwa? Ungakhathazeki, eli nqaku liza kukuxelela ngokweenkcukacha. Ngokwesiqhelo,Izikhanyiso zesitalato ze-LEDUza kuhlolisisa ngezantsi iinkalo ezi-5 zohlolo ngaphambi kokuba unikezele:
Isatifikethi esihambelanayo sezixhobo zokukhanyisa
Into yokuqala kukujonga ukuba ingaba isiqinisekiso esifanelekileyo sesibane sigqityiwe na.
II Ukuchongwa ngokukhawuleza komgangatho wokukhanya kwesitalato se-LED
Isibane sesitalato se-LED senziwe ikakhulu ngomthombo wokukhanya, umbane kunye nerediyetha. Umgangatho wezixhobo kunye nenkqubo esetyenziswayo ichaphazela ngokuthe ngqoixabiso lezibane zesitalatoUkuhlola kuqala kwiinkalo zezinto, kuvavanya ngokukhawuleza izinto ezikrwada kunye nenkqubo yezibane ze-LED ukuze kuchongwe umgangatho wezibane ze-LED.
1. Uvavanyo olupheleleyo lokusebenza kwe-photoelectric lwezixhobo zokukhanyisa ze-LED
Uvavanyo lokusebenza kwe-photoelectric lusisiseko esibalulekileyo sokuvavanya nokubonakalisa umgangatho wezibane ze-LED, ukukhangela ukuba kukho na ubukho bemigangatho yobuxoki.
2. Uvavanyo lomgangatho womthombo wokukhanya ophambili wezibane ze-LED
Ukufunyanwa komthombo wokukhanya kwe-LED kunye ne-bead yokukhanya:
(1) Uvavanyo lwenkqubo yelensi, uhlobo lweglue efakwe kwi-encapsulation, akukho zingcolisi, amaqamza, uvavanyo lokuqina komoya.
(2) Uvavanyo lwenkqubo yokugquma i-phosphor coating phosphor, ubungakanani be-phosphor particles, ukusasazwa kobungakanani be-particles, ukwakheka, nokuba kukho i-agglomeration kunye ne-settlement phenomenon.
(3) Uvavanyo lwenkqubo ye-chip, ukulinganiswa kwe-chip graphics microstructure, ukukhangela iziphene, ukuchonga ukungcola kwe-chip, nokuba kukho ukuvuza kunye nokwaphuka kombane.
(4) Uvavanyo lwenkqubo yokubopha i-lead, ukujongwa kwemo ye-welding yokuqala neyesibini, umlinganiselo wokuphakama kwe-arc, umlinganiselo wobubanzi, ukuchongwa kokwakheka kwe-lead.
(5) Inkqubo yekristale eqinileyo, uvavanyo lwenkqubo yekristale eqinileyo, nokuba kukho i-void yomaleko oqinileyo, nokuba kukho ukuhluma, ukwakheka komaleko oqinileyo, ubukhulu bomaleko oqinileyo.
(6) Uvavanyo lwenkqubo yokugquma nge-stent, ukwakheka kwe-stent, ukwakheka kwe-coating, ubukhulu be-coating, ukuqina komoya we-stent
3. Uvavanyo lokusebenza kokusasazwa kobushushu kwezixhobo zokukhanyisa ze-LED
Njengesibane esitsha esonga amandla, isibane sesitalato se-LED siguqula kuphela i-30-40% yamandla ombane abe kukukhanya kwaye okuseleyo kube ngamandla obushushu ngexesha lokukhanya. Kwaye ubomi kunye nomgangatho wezibane ze-LED kunxulumene kakhulu nobushushu. Ubushushu be-bead yokukhanya, ubushushu beqokobhe,ukusasazwa kobushushuUbushushu buya kunxulunyaniswa nokufana kwezibane ze-LED, umgangatho kunye nobomi benkonzo.
Ukuchongwa kokuchithwa kobushushu bezibane ze-LED kubandakanya iinkalo ezi-3 ezingezantsi:
(1) Uvavanyo loyilo lokusasaza ubushushu lwezibane ze-LED;
(2) Nokuba iqondo lobushushu lenxalenye nganye liphezulu kakhulu na emva kokuba ukukhanya kufikelelwe kumlinganiselo wobushushu;
(3) Ukufunyanwa kwezinto zokusasaza ubushushu ze-LED. Nokuba ukhetha ubushushu obuphezulu, umlinganiselo ophezulu wokuhambisa ubushushu bezinto zokusasaza ubushushu.
4. Ingaba izibane ze-LED zinezinto eziyingozi kumthombo wokukhanya
Umthombo wokukhanya we-LED uyoyika i-sulfur, kwaye ukusilela kwayo kungaphezulu kwe-50% okubangelwa yi-sulfur bromide chlorination yomaleko wesilivere weplating. Xa kuvela i-sulfur-bromine chlorination reaction yomthombo wokukhanya we-LED, indawo yokusebenza kwemveliso iya kuba mnyama, i-flux ekhanyayo iya kuncipha kancinci, kwaye ubushushu bombala buya kubonakala buhamba ngokucacileyo. Kwinkqubo yokusetyenziswa, kulula ukubonakala kwento yokuvuza kombane. Imeko embi ngakumbi kukuba umaleko wesilivere ubolile ngokupheleleyo, umaleko wobhedu uyavezwa, kwaye ibhola yegolide iyawa, nto leyo ebangela ukukhanya okufileyo. Izibane ze-LED ziqulathe izinto ezingaphezulu kwama-50 ezikrwada, ezinokuba nazo ziqulathe i-sulfur, chlorine kunye ne-bromine elements. Kwindawo evaliweyo, enobushushu obuphezulu, ezi zinto ze-sulfur, chlorine kunye ne-bromine zinokutshintsha zibe ziigesi kwaye zitshabalalise imithombo yokukhanya ye-LED. Ingxelo yokuchonga ukukhutshwa kwe-sulfur kwezibane ze-LED ngundoqo wokuqinisekisa umgangatho ozinzileyo wezibane ze-LED.
5. Uvavanyo lomgangatho wombane we-LED
Umsebenzi wombane we-LED drive kukuguqula umbane we-AC ube ngumbane othe ngqo ofanelekileyo kwi-LED. Ekukhetheni nasekuyilweni kombane we-LED drive, ukuthembeka, ukusebenza kakuhle, amandla, imo yokuqhuba, ukhuseleko lokuhamba ngamandla, umsebenzi wokukhusela impendulo engalunganga kubushushu kunye nezinye izinto kufuneka ziqwalaselwe. Umbane we-LED drive kwizibane zangaphandle kufuneka uqwalasele ukusebenza okungangeni manzi kunye nokusebenza okungangeni manzi, kwaye iqokobhe layo kufuneka lingatshisi ilanga kwaye lingabi lula ukuguga ukuqinisekisa ukuba ubomi bombane we-drive buyahambelana nobomi be-LED. Umxholo wokuchonga nokuvavanya uboniswe ngezantsi:
(1) Iiparamitha zokukhupha amandla: i-voltage, i-current;
(2) Nokuba umbane oqhubayo unokuqinisekisa iimpawu zokuphuma kombane oqhubekayo, imo yokuqhuba yombane oqhubekayo okanye imo yokuqhuba yombane oqhubekayo oqhubekayo;
(3) Nokuba kukho ukhuseleko oluhlukeneyo olusebenzisa i-overcurrent, ukhuseleko lwe-short circuit kunye nokhuseleko lwe-open circuit;
(4) ukuchongwa kokuvuza kombane: xa usebenza ngombane, iqokobhe akufuneki libe nemeko yombane;
(5) Ukufunyanwa kwe-Ripple voltage: akukho voltage ye-ripple yeyona ilungileyo, xa i-ripple voltage incinci, incochoyi ingcono;
(6) Uvavanyo lweStrobogram: ingaba isibane sesitalato se-LED sikwistrobogram emva kokukhanyisa na;
(7) I-voltage/umbane ophumayo kwisiqalo: xa kuqaliswa, umbane ophumayo akufuneki ubonakale umbane omkhulu/umbane ophumayo;
(8) Ingaba ukunyuka kwamandla kuyahambelana na nemigangatho efanelekileyo.
Ukuchongwa komthombo we-III Chip
Isiseko sedatha seetshiphusi ze-LED esivavanyiweyo sinolwazi lweetshiphusi zabavelisi abaninzi basekhaya nabangaphandle, idatha iphelele, ichanekile kwaye ihlaziywa ngokukhawuleza. Ngokufumana kunye nokudibanisa, imodeli yeetshiphusi kunye nomenzi wayo inokuqinisekiswa, nto leyo eluncedo kubavelisi bokukhanyisa ukuphucula ulawulo lomgangatho kunye nokusebenza kakuhle.
IV Ukuhlolwa kwenkangeleko kunye nolwakhiwo lwezixhobo zokukhanyisa ze-LED
1. Incwadi yebhidi idla ngokubonelela ngezinto ezisetyenziselwa ukukhanyisa, kwaye ezi zibonelelo ziya kuhlolwa ngokweenkcukacha. Ukuhlolwa kwenkangeleko: umbala wokugquma uyafana, akukho mingxunya, akukho mifantu, akukho kungcola; Ukugquma kufuneka kunamathele ngokuqinileyo kwizinto ezisisiseko; Umphezulu weqokobhe lazo zonke iindawo zezibane ze-LED kufuneka ube mpuluswa, ungabi nemikrwelo, imifantu, ukuguquguquka kunye nezinye iziphene;
2. Ukuhlolwa kobukhulu: Ubukhulu kufuneka buhlangabezane neemfuno zemizobo;
3. Ukuhlolwa kwendibano: izikrufu zokubopha kumphezulu wokukhanya maziqiniswe, imiphetho mayingabi nazibharrs kunye nemiphetho ebukhali, kwaye uqhagamshelo lufanele luqine kwaye lukhululeke.
Uvavanyo lwe-V olungangeni manzi
Njengezibane ezisebenza ngaphandle kuyo yonke iminyaka, kwayeIzibane zesitalato ze-LEDzifakelwe kwindawo yomoya ukusuka kwiimitha eziliqela ukuya kwiimitha ezingaphezu kweshumi. Kunzima kakhulu ukutshintsha nokugcina izibane zesitalato zisebenza kakuhle, nto leyo efuna ukuba zisebenze kakuhle xa zingangeni manzi kwaye zingangeni uthuli. Ke ngoko, umgangatho wokukhanya kwesitalato se-LED okungenamanzi nothuli ubaluleke kakhulu.
Njengoko kubonisiwe kumfanekiso, iZenith Lighting ngumvelisi ochwephesha weentlobo ngeentlobo zezibane zesitalato kunye nezinye iimveliso ezinxulumene noko, ukuba unemibuzo okanye iprojekthi, nceda ungathandabuzi ukuqhagamshelana nathi.
