Iimfihlo ezilishumi ezincinci zeTekhnoloji yesibane sesitalato se-LED

Iprojekthi yokukhanyisa i-LED yenkampani yokukhanyisa ayichaphazeli nje kuphela indawo engqongileyo yehlabathi, kodwa kunye neempawu zayo ezikhethekileyo zeshishini. Umbane wokukhanya kwesitrato se-LED yeyona nto iphambili kuphuhliso lwangoku lwe-LED. Kuyilo oluhambelanayo kwitekhnoloji ye-LED, okwangoku kukho izisombululo ezininzi kunye nobuchule bokuyila obukhethekileyo. Makhe sijonge kubo nganye nganye. Kutheni umbane wesibane sesitalato se-LED uhlala uhleli? Iimpawu zezixhobo zokukhanyisa i-LED zigqiba ukuba zinempembelelo enkulu kwindalo. Ngokomzekelo, utshintsho lweqondo lokushisa luyenyuka, i-current ye-LED iya kwanda, i-voltage iyanda, kwaye i-current ye-LED iya kwanda. Ixesha elide ukugqwesa umsebenzi wangoku olinganisiweyo kuya kunciphisa kakhulu amaso ezibane ze-LED. I-LED eqhubekayo yangoku kukuqinisekisa ukuba ixabiso layo langoku elisebenzayo alitshintshi xa iimeko zokusingqongileyo ezifana nobushushu kunye nokutshintsha kombane. 2. Umbane wesibane sesitalato se-LED ukuchaneka kwe-Hengli ukuchaneka okuqhubekayo kwangoku kwimarike kumbi, njengeskimu sokuthandwa kwimarike, njengesicwangciso somlambo esithandwayo, impazamo ifikelela ±I-8%, impazamo yangoku eqhubekayo inkulu kakhulu. Kufuneka ngokubanzi ±3%. Ngokwe-3% yeskim soyilo. Unikezelo lwamandla emveliso kufuneka lulungiswe kakuhle phambi kokuba luphunyezwe ±3% Impazamo. 3. Umbane osebenzayo we-LED yesibane sesitalato unikezelo lwamandla ombane ngokubanzi 3.0-3.5V. Emva kokuvavanya, uninzi lwazo lusebenza kwi-3.2V, ngoko ke ukubalwa kwe-3.2V kunengqiqo. Amandla ombane ewonke amaso esibane se-n kuthotho = 3.2 * N4, isibane se-LED yesibane sombane wesitrato sangoku sisona sifanelekileyo, njengomsebenzi olinganisiweyo we-LED 350 mAh, ezinye iifektri zisetyenziswa ekuqaleni, kunye noyilo 350 mAh. Enyanisweni, umsebenzi ophantsi kwalo mjelo ushushu kakhulu. Emva kweemvavanyo ezininzi zokuthelekisa, kufanelekile ukuyilwa njenge-320 mAh. Zama ukunciphisa ukushisa kweenwele, ukuze umbane ongaphezulu ube namandla okukhanya abonakalayo. 5. Ububanzi kangakanani uchungechunge kunye nobubanzi bombane webhodi yombane yesibane sesitalato se-LED? Ukwenza ukukhanya kwesitrato se-LED kusebenze kuluhlu lwe-voltage yegalelo, i-AC85-265V, uchungechunge lwe-LED kunye nendlela yokudibanisa ibhodi yokukhanya ibaluleke kakhulu. Zama ukungasebenzisi i-voltage ebanzi kangangoko kunokwenzeka, inokwahlulwa ibe yi-AC220V, kwaye i-AC110V ihlelwe ngokusemandleni, ukuze kuqinisekiswe ukuthembeka kombane. Ekubeni unikezelo lwamandla lwangoku luyi-non-isolation -voltage rhoqo unikezelo lwamandla lwangoku, xa i-voltage i-110V, i-voltage ye-output ayidluli i-70V, kwaye inani le-series alidluli i-23 string. Xa igalelo lombane li-220V, i-voltage ephumayo inokufikelela kwi-156V. Ngamanye amazwi, inani lothotho alidluli kumtya we-45. Ungabi nenani elihambelanayo kakhulu, ngaphandle koko ukusebenza kwangoku kukhulu kakhulu, kwaye umbane ushushu kakhulu. Kukho kwakhona isisombululo esibanzi-voltage. Imbuyekezo yamandla yomthombo we-APFC kukusebenzisa i-L6561/7527 ukunyusa amandla ombane ukuya kwi-400V, kwaye emva koko unciphise umbane. Esi sisombululo sisetyenziswa kuphela phantsi kweemeko ezithile. I-6, i-isolation / non-isolation jikelele ukunikezelwa kwamandla odwa, ukuba yenziwe kwi-15W, ifakwe kwi-LED yesitrato sokukhanya kombhobho wamandla, i-transformer yayo inkulu kakhulu, kunzima ukuyifaka. Ngokukodwa kuxhomekeke kwisakhiwo sendawo kuxhomekeke kwimeko ethile. Ngokuqhelekileyo, ukuhlukaniswa kunokufezekisa kuphela i-15W, ngaphantsi kwe-15W, kwaye ixabiso libiza kakhulu. Ngoko ke, indleko-ukusebenza kakuhle kokuzihlukanisa ayiphezulu. Ngokuqhelekileyo, ii-akhawunti ezingezizo zodwa zezona ziqhelekileyo, umthamo unokuba mncinci, kwaye ubuncinci bunokuba ngu-8 mm ukuphakama. Enyanisweni, amanyathelo okhuseleko angengawodwa ayenziwa. Isithuba esivumelekileyo sinokusetyenziswa njengonikezelo lwamandla lodwa. 7. Umbane we-LED wesitrato unokudityaniswa njani nebhodi yesibane yesibane? Abanye abathengi baqala ukuyila ibhodi yesibane, kwaye emva koko bafumana umbane. Kunzima ukufumana unikezelo lwamandla olufanelekileyo, nokuba langoku likhulu kakhulu, kwaye i-voltage incinci kakhulu (efana ne-7x1wi > I-350mA, okanye i-V25V), umphumo kubushushu obunzima, ukusebenza kakuhle okuphantsi, okanye ukungonelanga koluhlu lwamandla ombane. Enyanisweni, ukukhetha indlela efanelekileyo yokudibanisa ne-LED nganye iyafana, kodwa umphumo wokunikezelwa kwamandla unokusebenzisa ukusebenza kakuhle. Eyona ndlela ilungileyo kukunxibelelana nabavelisi bamandla kuqala kunye ne-talor-made. Okanye uvelise umbane. 8. I-LED's skewers kunye ne-PFC power factor alolation igalelo AC220V high -voltage end electrolytic capacitance capacity is generally input power 1W = 1UF, AC110V1W = 2UF okwangoku ineemeko ezintathu zobonelelo lombane PFC: enye ayinayo i-PFC ngaphandle kwembuyekezo yembuyekezo yamandla Kwiisekethe ezizinikeleyo, Ixabiso le-PF ngokubanzi lijikeleze i-0.65; eyesibini yimbuyekezo yamandla e-passive factor imbuyekezo yesekethe ye-PFC, oko kukuthi, ukukhanya kwembuyekezo ye-passive factor factor, kunye nebhodi yesekethe yokuhamba ngoku yeyona nto ithembekileyo, PF PF, PF Ixabiso ngokubanzi lijikeleze i-0.92; iintlobo ezintathu zesekethe esebenzayo ye-7527/6561 nayo isetyenziswa, oko kukuthi, imbuyekezo yomthombo wamandla ombane, ebizwa ngokuba yi-AC220V kwisekethe ye-APFC, i-AC110V inokusebenzisa i-electrolytic capacitors yomthamo ofanayo, khetha i-1W = 1W = 1.5uf. Ixabiso le-PF linokufikelela kwi-0.99, kodwa iindleko zesi sisombululo zibi kakhulu kunesisombululo sesibini. Ngoko isisombululo sesibini sisetyenziswa ngakumbi. Kwisekethe ye-PFC engasebenziyo: ekwabizwa ngokuba yiChan -uhlobo lwe-PFC isekethe, uluhlu lwamandla ombane osebenzayo we-DC sisiqingatha sencopho yombane wegalelo le-AC. Ukuba igalelo li-220V, i-peak yayo yi-220 * 1.414 = 312V, kunye nesiqingatha se-voltage ephezulu yi-156V. Ke ngoko, inani le-LED ukukhanya kwesitrato ubuhlalu ukuya kuthi ga kwi-45 umtya ongezantsi. Ngoko ke, ukuba ufuna ukufumana izinto ezinkulu zamandla, inani lezibane kufuneka lingabi lincinci kakhulu, kungenjalo owona mbuso usebenzayo awuyi kufezekiswa. Amandla ombane kufuneka ahlangabezane namandla aphumayo. Okukhona kuncinci ukusebenza kwangoku kwamacandelo e-elektroniki kuluhlu lwamandla ombane alinganisiweyo, kokukhona ubomi bubude, kokukhona ubomi bufutshane. Amaso ombane okukhanya kwesitrato se-LED anovelwano kakhulu kubungakanani bonxibelelwano. Okukhona ubuninzi bonxibelelwano, kokukhona ukuthuthuzela kokukhanya. Ngokuqhelekileyo, i-electrolytic capacitors kufuneka isetyenziswe ukugcina i-voltage, kwaye i-voltage ye-voltage yokuphela kwemveliso isetyenziswe kangangoko kunokwenzeka. Umthamo we-electrolytic capacitance end of voltage ezantsi akufanele ube mncinci kakhulu. I-non-isolation input end high-voltage electrolytic capacitance selection iyafana neyodwa, kwaye i-output-end capacitor ikhetha i-1UF.
