IFomu yoQhagamshelwano lwesibane sesibane se-LED, iSicombululo esiQhelekileyo sokuFailure seeModyuli zokuKhanya kwe-LED

Izibane zezibane ze-LED Iindlela eziqhelekileyo zoqhagamshelwano 1. Ifomu yokudibanisa ngokubanzi (1) Iifom zechungechunge ezilula Ngokuqhelekileyo kunye neendlela ezilula zokudibanisa ii-LED1 ze-LEDN zixhunyiwe ekuqaleni kunye nomsila, kunye nokuhamba kwangoku ngexesha le-LED lilingana. Kwii-LED zeenkcukacha ezifanayo kunye neebhetshi, nangona i-voltage kwi-LED enye inokuba nomahluko omncinci, kuba i-LED sisixhobo sangoku, inokuqinisekisa ukuba ukukhanya kwabo okukhanyayo kuyahambelana, kubanjwe oku, iifom ezilula zeefom zokwakheka. I-LED ineempawu zesekethe elula kunye noqhagamshelwano olufanelekileyo. Nangona kunjalo, ngenxa yokusetyenziswa kochungechunge, xa enye yee-LED zenzeke, zonke izibane ze-LED ziya kucinywa, eziza kuchaphazela ukuthembeka kokusetyenziswa. (2) Iifom zechungechunge ze-ode-pole diode kunye nokudibanisa kwe-Qina diode zixhunywe kwifom yokudibanisa yochungechunge oluphuculweyo lwe-Qiner diode ngokufanayo. Kule ndlela yokudibanisa, i-voltage yokuqhawula ye-Zina diode nganye iphezulu kunombane osebenzayo we-LED. Xa usebenza ngokuqhelekileyo, ngenxa yokuba i-Qina diode VD1 VDN, okwangoku ihamba phambili kwi-LED1 LEDN. Xa i-LED eyonakalisiwe kwintambo ye-LED ibangelwa Ukongeza kwi-LED ephosakeleyo, ezinye ii-LED zisenayo imisinga ngoku kunye nokukhanya. Le ndlela yokudibanisa iphuculwe kakhulu ngokuthelekisa ukuthembeka ngokubhekiselele ekuthembekeni. Ifom ehambelanayo iyonke (1) Ifom ye-parallel elula Ilula kwaye idibeneyo ye-LED1 ye-LEDN yentloko kunye nomsila ngokuhambelana, i-LED nganye ilingana ne-LED nganye. Inokubonwa kwiimpawu ze-LED. Kungokwesixhobo sangoku, kwaye utshintsho oluncinci kwi-voltage eyongezwe kwi-LED luya kubangela utshintsho olukhulu lwangoku. Ukongezelela, ngenxa yokunciphisa iteknoloji yokuvelisa i-LED, kunye ne-batch efanayo ye-LEDs, umehluko ekusebenzeni yinto engokwemvelo, ngoko xa i-LED1 i-LEDN isebenza, nabani na ochitha i-LED nganye ayilingani. Ingabonwa ukuba ukuhanjiswa okungalinganiyo kwe-LED nganye yangoku kunokubangela ukuba ubomi be-LED bangoku bube bukhulu kakhulu, kwaye buphele. Nangona le ndlela yokudibanisa ilula. Kodwa ukuthembeka akukho phezulu, ngakumbi kwizicelo kwimeko yee-LED ezininzi. (2) Ifom ehambelanayo yokulinganisa ngokuzimeleyo ijolise ekuthembekeni kwe-parallelism elula. Ifom ehambelanayo yokudibanisa ngokuzimeleyo yindlela efanelekileyo. I-LED nganye ngale ndlela ikhoyo ngoku i-adjustable current (i-terminal ye-Voutput ye-drive yi-L1 Ln, ngokulandelanayo), kwaye iqinisekise ukuba i-current ejikelezayo kwi-LED nganye ingaphakathi kweemfuno zayo, kunye nemiphumo emihle yokuqhuba, i-LED enye, i-LED enye. Ukukhusela okupheleleyo, akuchaphazeli omnye umsebenzi we-LED xa iziphene, kwaye unokufanisa iimpawu ze-LED ezinomahluko omkhulu. Ingxaki ephambili yobukho kukuba: ukubunjwa kwesiphaluka sonke somqhubi kunzima kakhulu, ixabiso lesixhobo liphezulu, kwaye umthamo womsebenzi unzima kakhulu. Ayifanelekanga kwinani elikhulu leesekethe ze-LED. Iifom ezixubileyo ezidibeneyo zicetywayo ngokudibanisa iingenelo ezichaphazelekayo zochungechunge kunye neefom ezifanayo. Iifom eziphambili zezi zimbini zilandelayo. (1) Xa iifom ezidibeneyo zokwakheka ziqala, inani lezicelo ze-LED likhulu, kwaye uchungechunge olulula okanye uxhulumaniso oluhambelanayo alunangqiqo. Owokuqala ufuna ukuba owokuqala acele i-voltage ephezulu ye-drive (i-N amaxesha ombane we-LED enye ye-VF). Ukuwa i-drive nge yangoku enkulu (N amaxesha enye LED yangoku IF). Oku kuzisa ubunzima kuyilo kunye nokuveliswa komqhubi, kwaye kubandakanya iingxaki zesakhiwo kunye nokusebenza kakuhle kwesekethe yokuqhuba. I-voltage yokusebenza yenani le-LED kwi-series kunye ne-voltage yokusebenza ye-VF enye ye-LED imisela umbane wokuphuma kwamandla okuqhuba; Ixabiso le-NVF limisela amandla emveliso yedrive. Ngoko ke, indlela yokuxuba emva kokuxuba ngokukodwa kukuqinisekisa ukuba kukho ukuthembeka okuthile (impazamo ye-LED kumtya ngamnye ichaphazela kuphela ukukhanya okuqhelekileyo komtya), kunye nokuhambelana kwesekethe yokuqhuba ), Iphucula ukuthembeka kuneefom zechungechunge ezilula. . Isiphaluka sonke sineempawu zesakhiwo esilula, uxhulumaniso olufanelekileyo, kunye nokusebenza okuphezulu. Ifanelekile kwizicelo ezinenani elikhulu le-LED. (2) Ii-LED ezininzi ezixutywe kunye nomtya wentsebenziswano kuqala kwaye emva koko i-skewers iqala kwaye ifakwe umtya. Ekubeni i-LED1-N i-LEDM-N iqala ukudibanisa ukudibanisa, okuphucula ukuthembeka kweqela ngalinye le-LED, kodwa oku kubalulekile. Ngenxa yesi sizathu, unokukhetha i-voltage esebenzayo kunye nekhoyo ngoku kangangoko kunokwenzeka njengeqela elihambelanayo ngokudibanisa, okanye ukusombulula ukuxhathisa okuncinci kwangoku kwe-LED nganye. Ezinye iimpawu kunye neengxaki ezikhoyo zale fomu edibeneyo ifana nayo. (3) Iifom ze-cross-array ze-cross-arrays ziyizona zokuphucula ukuthembeka komsebenzi we-LED kunye nokunciphisa izinga lokungaphumeleli. Indlela ephambili yokubunjwa yile: uluhlu ngalunye lwee-LED ze-3 njengeqela, kunye ne-VA, VB, kunye ne-VC yee-terminal zokuphuma ezidityaniswe kwi-drive output ye-drive. Xa ii-LED ze-3 zochungechunge ziqhelekileyo, ii-LED ze-3 zikhanya ngexesha elifanayo; kanye ukuba i-LED enye okanye ezimbini zingasebenzi, inokuqinisekisa ukuba ubuncinane i-LED enye isebenza ngokwesiqhelo. Ngale ndlela, inokuphucula kakhulu ukuthembeka kweqela ngalinye lokukhanya kwe-LD, kwaye inokuphucula ukuthembeka okupheleleyo kokukhanya kwe-LED yonke. 2. Udibaniso olwahlukileyo kunxibelelwano oluhlukeneyo luneempawu zazo, kwaye iimfuno zomqhubi zahlukile, ngakumbi xa i-LED enye isilela ukusilela kumsebenzi wesiphaluka, ukuthembeka kokukhanya ngokubanzi, kwaye uqinisekise ukuba i-LED iyonke inokuba kangangoko kunokwenzeka kangangoko kunokwenzeka. Kubaluleke kakhulu ukuqhubeka nokubanakho komsebenzi kunye nokunciphisa ukusilela kwe-LED ngokubanzi, njl. Lilonke, izicelo zeqela le-LED ziyindlela ebalulekileyo yezicelo ezichanekileyo ze-LED. Ukudityaniswa kwe-LED okwahlukileyo kubalulekile kwii-LED ezinkulu kunye neemfuno zoyilo lweesekethe zokuqhuba. Ke ngoko, ekudityanisweni kweesekethe zokwenyani, ukhetho oluchanekileyo lwendlela yoqhagamshelo lwe-LED oluhambelanayo lubalulekile ekuphuculeni isiphumo sesiphumo esikhanyayo, ukuthembeka komsebenzi, ukusebenziseka koyilo lomqhubi kunye nokwenziwa, kunye nokusebenza kakuhle komqhubi. yonke isiphaluka. Ukungaphumeleli kwemodyuli ekhanyayo ye-LED kunye nesisombululo: konke ukukhanya kwe-LED; Umbuzo: ukunxibelelana kakubi; isisombululo: ukulungiswa kwakhona okanye ukufakwa; isenzeko: I-LED dim; Umbuzo woku-1.
