Kumele -bona: Ulwazi Lolwazi Lwamandla Omshayeli We-LED

Ukukhipha ukushisa, amandla okushayela, nemithombo yokukhanya kuyizingxenye ezibaluleke kakhulu zomkhiqizo omuhle wokukhanyisa kwe-LED. Nakuba ukukhishwa kokushisa kubaluleke kakhulu, umphumela wokukhipha ukushisa uthinta ngokuqondile ikhwalithi yokuphila yemikhiqizo yokukhanyisa, kodwa umthombo wokukhanya uyingxenye eyinhloko yawo wonke umkhiqizo. Ukuzinza kwempilo nokuphumayo kwamanje kanye ne-voltage yesiphakeli samandla ngokwako kunomthelela omkhulu kukhwalithi yempilo iyonke yomkhiqizo. Ukunikezwa kwamandla komshayeli we-LED nakho kungumkhiqizo osekelayo. Njengamanje, ikhwalithi yokunikezwa kwamandla emakethe ayilingani. Okulandelayo kunikeza ulwazi oluhlobene namandla omshayeli we-LED. 1. Iyini idrayivu ye-LED amandla kagesi wedrayivu ye-LED eguqula ukunikezwa kwamandla kugesi othize wamanje ukuze ishayele isiguquli sevolthi esikhanyayo se-LED. Ngokuvamile: okokufaka kwamandla okushayela kwe-LED kuhlanganisa i-high -voltage frequency AC (okungukuthi, amandla edolobha), i-voltage ephansi DC DC , High -voltage DC, low -voltage kanye ne-high -frequency AC (njengokukhipha ama-electronic transformers), njll. Ukukhishwa kwamandla kagesi wedrayivu ye-LED ngokuvamile kuwumthombo wamanje ongashintshi ongashintsha i-voltage ngezinguquko ekuncishisweni kwenani le-voltage eya phambili ye-LED. Izingxenye eziyinhloko zokunikezwa kwamandla e-LED zifaka isilawuli sokushintsha, induction, switch component (MOSFET), ukumelana nempendulo, idivayisi yesihlungi sokufaka, idivayisi yesihlungi esikhiphayo, njll. Ngokwezidingo zezikhathi ezihlukene, kufanele kube namasekhethi okuvikela i-overvoltage, i-input -lack pressure protection circuits, ukuvikelwa komgwaqo we-LED, ukuvikelwa kwe-overcurrent kanye nezinye izifunda. 2. Izici ze-LED drive power supply (1) Ukuthembeka okuphezulu ikakhulukazi kufana namandla omshayeli wezibani ze-LED zomgwaqo, ezifakwe endaweni ephakeme, akulula ukulungiswa, futhi izindleko zokuzilungisa nazo zinkulu. (2) I-LED esebenza kahle kakhulu iwumkhiqizo owonga amandla, futhi ukusebenza kahle kwamandla okushayela kuphezulu. Kubaluleke kakhulu ukuchithwa kokushisa kokunikezwa kwamandla esibani. Ukusebenza kahle kokunikezwa kwamandla kuphezulu, ukulahlekelwa kwesisindo kuncane, futhi ukushisa esibani kuzoba kuncane, okuzonciphisa izinga lokushisa lesibani. Kuyazuzisa ukubambezela ukuhluleka kokukhanya kwe-LED. (3) Izici zamandla aphezulu kanye nezici zamandla ziyizidingo zomthwalo wegridi yegridi. Ngokuvamile, izinto zikagesi ezingaphansi kwama-watts angu-70, azikho izinkomba eziphoqelekile. Nakuba isici samandla esisodwa esinamandla aphansi, izici zamandla aphansi zinomthelela omncane kugridi yamandla, ukusetshenziswa kwezibani ebusuku, uhlobo olufanayo lomthwalo lugxile kakhulu, kuzodala ukungcoliswa okubi kakhulu kugridi yamandla. Ngamandla omshayeli we-LED we-30 watts 40 watts, kuthiwa esikhathini esizayo esiseduze, kungase kube nezinkomba ezithile zezici zamandla. (4) Kunezinhlobo ezimbili zezindlela zokushayela manje: eyodwa ingumthombo wamandla kagesi ongashintshi wemithombo eminingi yokusakaza engashintshi, kanye nomthombo ngamunye wamanje ongashintshi womthombo ku-LED ngayinye ngokuhlukile. Ngale ndlela, inhlanganisela iyaguquguquka, ukuhluleka kwe-LED yonke indlela, akuphazamisi umsebenzi wamanye ama-LED, kodwa izindleko zizoba phezulu kancane. Enye ingumthombo wamandla wamanje ongashintshi, nawo okhona “UZhongke Huibao “Indlela yokushayela eyamukelwayo, i-LED ixhunyiwe noma ihambisana. Inzuzo yayo ukuthi izindleko ziphansi, kodwa ukuguquguquka kumpofu, futhi kuyadingeka ukuxazulula inkinga yokuhluleka okuthile kwe-LED, okungaphazamisi ukusebenza kweminye imisebenzi ye-LED. Lezi zinhlobo ezimbili zihlala isikhathi eside. Izindlela zokukhipha amandla kaMulti -Lu Hengliu zizoba ngcono ngokwezindleko nokusebenza. Mhlawumbe isiqondiso esivamile esikhathini esizayo. (5) Amandla okuvikela ukuvikelwa kwe-LED yama-LED ampofu uma kuqhathaniswa, ikakhulukazi amandla kagesi e-anti-reverse. Ukuqinisa ukuvikeleka kule ndawo nakho kubalulekile. Amanye amalambu e-LED afakwe ngaphandle, njengamalambu e-LED street. Ngenxa yokuvulwa komthwalo wegridi yamandla kanye nokungeniswa kweziteleka zombani, uhlelo lwegridi luzohlasela amagagasi ahlukahlukene, futhi amanye amagagasi azodala umonakalo we-LED. Ngakho-ke ukuhlaziya “UZhongke Huibao “Amandla omshayeli kufanele antule ekuvikeleni ukukhuphuka kwamagagasi. Ngokuqondene nokushintshwa okuphindaphindiwe kwamandla nezibani, amandla kagesi we-LED kufanele abe namandla okucindezela ukukhuphuka nokuvikela ikhono le-LED ukuthi lingalinyazwa. (6) Ngokungeziwe kumsebenzi ojwayelekile wokuvikela, amandla okusebenza kokuvikela angcono kakhulu ukwengeza impendulo engemihle yezinga lokushisa le-LED ekuphumeni okuqhubekayo kwamanje ukuze kuvinjelwe izinga lokushisa le-LED ukuthi lingabi phezulu kakhulu;. 3. Ukuhlelwa ngokwendlela yokushayela (1) Okukhiphayo kwamanje kwesekethe yedrayivu eqhubekayo yamanje ayishintshi, kuyilapho amandla kagesi e-DC ashintsha phakathi kwebanga elithile ngosayizi wokumelana nomthwalo, inani lokumelana nomthwalo lincane, okukhiphayo I-voltage ithi Uma iphansi, inani lokumelana nomthwalo likhulu, i-voltage ephumayo iyanda; umjikelezo wamanje oqhubekayo awesabi umthwalo wesifunda esifushane, kodwa umthwalo uvinjelwe ngokuqinile; isifunda sokushayela i-Hengliu singcono kakhulu, kodwa intengo iphakeme kakhulu; qaphelani; qaphela Isilinganiso esiphezulu sokubekezelelana kanye nevelu ye-voltage esetshenzisiwe, ikhawulela inani lama-LED. (2) Ngemva kokunqunywa kwemingcele ehlukahlukene kumjikelezo wokuzinzisa, i-voltage ephumayo ilungisiwe, futhi umphumela wamanje ushintsha ngokukhula nokuncipha komthwalo; Isifunda esifushane; shayela i-LED ukuze ishayele isekethe eqhutshwa yi-voltage, intambo ngayinye idinga ukungeza ukumelana okufanele ukuze yenze intambo ngayinye yesibonisi se-LED sokukhanya okumaphakathi; ukukhanya kuzothintwa izinguquko ze-voltage kusukela ekulungisweni. 4. Izinzuzo nezinkinga zamanje ezingaguquki zizonke kanye nendlela yokulandela indlela iqhathaniswa nomthamo wamanje ophelele. Nakuba kunezinto eziningi ezimbi nezindleko eziphakeme, izindleko ziphakeme uma kuqhathaniswa. Kodwa ingavikela ngempela impilo ye-LED futhi inwebe i-LED, ngakho ukugeleza okuqhubekayo komgwaqo kuwumkhuba wesikhathi esizayo. 5. Ukuntuleka kwamandla kagesi we-LED Amandla kagesi ashayelwa yi-LED akwanele okwamanje: 1. Ochwepheshe bezinkampani ezikhiqiza ukukhanya kwe-LED kanye nemikhiqizo ehlobene abazi ngokwanele mayelana nokushintshwa kwamandla kagesi. Futhi ukungacabangi ukuhambisana kwe-electromagnetic ngokwanele, kusekhona ezinye izingozi ezifihliwe; 2. Iningi labakhiqizi bamandla kagesi we-LED baguqulwa basuka ekushintsheni okujwayelekile kokuphakelayo ukuze benze ugesi we-LED. Izici nokuqonda kwe-LED akwanele; Cishe awekho amazinga, amaningi awo ayindinganiso yokubhekisela ekunikezeni amandla okushintshwa kanye nesilungisi se-elekthronikhi; Iningi lamandla kagesi we-LED alifani, ngakho-ke iningi lemali lincane uma kuqhathaniswa. Uma umthamo wokuthenga umncane, intengo iphezulu, futhi umphakeli wengxenye akabambisani kakhulu; 4. Ukuzinza kwamandla kagesi we-LED: okokufaka kwe-voltage ebanzi, izinga lokushisa eliphezulu kanye nomsebenzi wokushisa ophansi, izinga lokushisa elingaphezu kokushisa, ukuvikelwa kwe-overvoltage nezinye izinkinga azizange zizixazulule ngayinye ngayinye. Eyokuqala impilo yonke yesifunda sokushayela, ikakhulukazi amadivaysi ayisihluthulelo njengokuthi: ukuphila kwama-capacitor ekushiseni okuphezulu kuthinta ngqo impilo yokunikezwa kwamandla; ukuthi idrayivu ye-LED kufanele inselele ukusebenza kahle kokuguqulwa okuphakeme, ikakhulukazi uma ushayela ama-LED anamandla amakhulu, ngoba ngenxa yokuthi ishayelwa amandla amakhulu e-LED, ngoba ishayelwa yi-high-power LED, ngoba ngenxa yokuthi umshayeli une-high-power LED ingoba yomshayeli wamandla aphezulu e-LED, ngoba ngenxa yokuthi i-LED ephezulu -amandla omshayeli, ngoba i-LED ephezulu -amandla omshayeli, ngoba i-LED yomshayeli -amandla aphezulu, ngoba ngenxa yokuthi ingamandla aphezulu omshayeli I-LED, ngoba iyi-LED ephezulu yamandla omshayeli, ngenxa yokuthi iyi-LED ephezulu yamandla omshayeli, ngoba iyi-LED yamandla aphezulu omshayeli, ngoba iyi-LED ephezulu yamandla omshayeli, ngoba ngoba i-LED ephezulu yamandla omshayeli ingenxa yokuthi iyiqiniso nakakhulu, ngoba injalo nakakhulu. Wonke amandla angaphumi ekukhanyeni asetshenziswa njengokuchitha ukushisa, futhi ukusebenza kahle kokuguqulwa kwamandla kuphansi kakhulu, okuthinta ukusebenza kwemiphumela yokulondoloza amandla e-LED. Njengamanje, kuzicelo ezinamandla amancane (1-5W), inani lezindleko zokunikezwa kwamandla okushayela i-Hengliu selisondele ku-1/3, eliseduze nezindleko zemithombo yokukhanya, okuthinta ukukhushulwa kwemakethe ngezinga elithile. .
