Izibane zesibane se-LED ziqhele ukusetyenziswa kwiindlela zoQhagamshelo

Ifom yokumisela i-LED kwisicelo ixhomekeke kwizinto ezininzi, kubandakanywa iiparamitha ze-LED kunye nobuninzi, i-voltage yegalelo, ukusebenza kakuhle, ukulawula ukutshatyalaliswa kobushushu, ubungakanani kunye nezithintelo zokubeka kunye ne-optics, njl. Eyona fomu ilula yoqwalaselo yi-LED enye. Ngenxa yokuba iinqwelomoya zivame ukufunwa kwiziganeko zangempela zesicelo, ii-LED ezininzi kufuneka zilungelelaniswe kwaye zidibaniswe njengoko zifunekayo ukuhlangabezana neemfuno zesicelo sobukhulu obukhulu, ukukhanya okuphezulu, umboniso oguqukayo, ukuguqulwa kombala, kunye neemfuno ezihambelanayo ze-LED kunye nabaqhubi abaxhasayo. I. Uhlobo lonxibelelwano Iifom zechungechunge ezilula zixhunywe ngokubanzi kwi-LED1 ye-LEDN ngendlela yeefom zokudibanisa ezilula, kunye nokuhamba kwangoku ngexesha le-LED lilingana. Kwii-LED ezineenkcukacha ezifanayo kunye neebhetshi, nangona i-voltage kwi-LED enye ingaba nentlukwano encinci, kuba i-LED iyisixhobo samanje, inokuqinisekisa ukuba ukukhanya kwabo okukhanyayo kuyahambelana. Ngoko ke, uchungechunge olulula lwe-LED luneempawu zeesekethe ezilula kunye nokudibanisa okulula kunye nezinye iimpawu. (Izinto ezingalunganga: Ngenxa yokusetyenziswa kochungechunge, xa enye ye-LED ingaphumeleli, zonke izibane ze-LED ziya kucinywa, eziya kuchaphazela ukuthembeka kokusetyenziswa. ) 2. Iifom zechungechunge ezimbini ze-pole diode kunye nokudibanisa kwe-Qina diode zixhunywe kwifom yokudibanisa ephuculweyo ye-Qina 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 ayiqhubi, okwangoku ngokuyinhloko ihamba nge-LED1 LEDN. Xa i-LED eyonakalisiweyo kwintambo ye-LED ibangelwa Ukongeza kwi-LED, ezinye ii-LED zisenayo imisinga edlulayo kwaye ikhanya. I-akhawunti kawonkewonke ye-WeChat: I-Shenzhen LED Chamber of Commerce (le ndlela yokudibanisa kunye nefom yechungechunge elula iphucule kakhulu ukuthembeka ngokubhekiselele ekuthembekeni. ) Okwesibini, ifom ehambelanayo iyonke 1. Ifom ehambelanayo elula, elula kwaye edibeneyo ye-LED1 ye-LEDN yomsila wentloko, i-LED nganye ilingana nombane ofanayo, umbane olinganayo. 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 yee-LED, kukho ukungafani ekusebenzeni. Ngoko ke, xa i-LED1 i-LEDN isebenza, i-current flowing kwi-LED nganye ayilingani. Ingabonwa ukuba ukuhanjiswa okungalinganiyo kwe-LED nganye yangoku kunokubangela ukuba ubomi be-LED bangoku bube bukhulu kakhulu, kwaye buphele. (Izinto ezingalunganga: Nangona le ndlela yokudibanisa ilula, kodwa ukuthembeka akuphezulu, ngakumbi kwizicelo kwimeko yee-LED ezininzi. ) 2. Ifom ehambelanayo yokulinganisa ngokuzimeleyo ijolise ekuthembekeni kwe-parallelism elula. Ifom ehambelanayo ezimeleyo yindlela efanelekileyo. I-LED nganye ngale ndlela ine-adjustable yangoku (i-drive Voutput terminal yi-L1 Ln) ukuqinisekisa ukuba i-current ejikelezayo kwi-LED nganye ingaphakathi kweemfuno zayo, kunye nemiphumo emihle yokuqhubela phambili, ukukhuselwa kwe-LED eyodwa Gcwalisa, akuchaphazeli enye i-LED. sebenza xa iziphene, kwaye unokutshatisa iimpawu ze-LED ezinomahluko omkhulu. (Izinto ezingalunganga: Ukubunjwa kwesiphaluka sonke somqhubi kunzima, ixabiso lesixhobo liphezulu, umthamo uthatha kakhulu, awufanelekanga kwinani elikhulu leesekethe ze-LED. ) Okwesithathu, uhlobo oluxubileyo lokubunjwa okuxubileyo lucetywayo ngokudibanisa izibonelelo ezifanelekileyo zoluhlu kunye neefom ezifanayo. Iifom eziphambili zezi zimbini zilandelayo. 1. Xa iifom zokwakheka okuxubileyo ziqala, xa inani lezicelo ze-LED likhulu, uchungechunge olulula okanye uxhulumaniso oluhambelanayo alunangqiqo, kuba umqhubi ufuna umbane okhupha amandla aphezulu (amaxesha e-N yombane we-LED enye ye-VF), kunye nokugqibela. ifuna umqhubi afune umqhubi Imveliso yangoku enkulu (N amaxesha ombane we-LED enye ukuba). Oku kuzisa ubunzima kuyilo kunye nokuveliswa komqhubi, kwaye kubandakanya iingxaki zesakhiwo kunye nokusebenza kakuhle kwesekethe yokuqhuba. I-voltage yenani le-LED kwi-series kunye ne-voltage yokusebenza ye-VF enye ye-LED inquma i-voltage ephumayo yesixhobo sokuqhuba; Ixabiso limisela amandla emveliso yomqhubi. 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. . I-akhawunti kawonkewonke ye-WeChat: I-Shenzhen LED Chamber of Commerce (isiphaluka sonke sineempawu zesakhiwo esilula, uxhulumaniso olufanelekileyo, ukusebenza kakuhle, njl., ezifanelekileyo kwizicelo ezinenani elikhulu le-LED. ) 2. Ii-LED ezininzi ezixutywe kunye nomtya kuqala, kunye neendlela ezixubileyo zokudibanisa okuxubileyo phambi komtya. 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 zale fomu edibeneyo yokwakheka kunye neengxaki ezikhoyo ziyafana. ) Okwesine, iifom ze-cross-array ze-cross-arrays ziyizona zinto ziphucula 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. Isishwankathelo: Iifom zoqhagamshelo ezahlukeneyo zineempawu zazo ezahlukeneyo, kwaye iimfuno zomqhubi zahlukile, ngakumbi xa i-LED enye isilela ukusilela kumsebenzi wesekethe, ukuthembeka kokukhanya ngokubanzi, ukukwazi ukuqinisekisa i-LED iyonke kangangoko kunokwenzeka, ukukwazi ukuqhubeka nokusebenza kangangoko kunokwenzeka, ukukwazi ukuqhubeka nokusebenza, kubaluleke kakhulu ukunciphisa ukusebenza kakuhle kokusilela kwe-LED, 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.
