Onjiniyela abaningi abasebenza emboniniukushintsha ukunikezwa kwamandlaimbonibayahlanganyelaUkunikezwa kwamandla komshayeli we-LEDumklamo. Izinkampani eziningi zinezinhlobo ezintathu eziyinhloko zemiklamo yokunikezwa kwamandla kamshayeli:
Okokuqala. Isingeniso kanye nezici zeAmandla omshayeli we-LED
1. Isingeniso seAmandla omshayeli we-LED
Amandla omshayeli we-LED abhekisela emandleni aguqulwa abe ukukhanya kwe-LED ngesiguquli se-voltage (njenge-AC-DC).
Ngokuvamile, okokufaka kunguhigh-voltage industrial frequency ACezikhathini eziningi, okuyilokho esikubiza ngokuthi ugesi wamapayipi. ugesi omkhulu wezwe lami ungu-220V/50HZ, kanti ugesi omkhulu waseNyakatho Melika ungu-120V/60HZ; okwesibili, zikhonahigh-voltage kanye ne-low-voltage DC, njenge-12V, 24V kanye ne-36V, futhi kukhona ne-low-voltage high-frequency AC, njengei-electronic transformersisebenzisa sizokhipha i-voltage ehambisanayo.
2. Isimo samanje kanye nezici zeUkunikezwa kwamandla komshayeli we-LED
(1)Ukuthembeka okuphezulu, Ngokuvamile, iwaranti yezibani zaseNyakatho Melika ingafinyelela iminyaka emi-5, okuyinto enhle.
(2)Ukusebenza kahle okuphezulu, Ukusebenzisaukushintsha ukunikezwa kwamandlanoma ukunikezwa kwamandla olayini, ukusebenza kahle kwama-75~80% kuphezulu kakhulu.
(3)Isici samandla aphezulu, ngokuvamile efinyelela ngaphezu kuka-0.9, okusho ukuthi okokusebenza akwenzi umsebenzi ongasizi ngalutho, kusebenzisa amandla ngokuphumelelayo, futhi izibani zizohlala isikhathi eside.
(4) Inokuvikela okusebenzayo okufana nokuvikela i-surge, i-overvoltage kanye ne-undervoltage.
(5) Inemisebenzi yokumelana nothuli namanzi, njengezinga le-IP44.
(6) Inemithetho yezokuphepha kanye nokusebenza kokuhambisana kwe-electromagnetic.
(7) Abashayeli abathathu abavamile kuzoxoxwa ngakho ngezansi.
Okwesibili. Ezintathu ezivamileIzinsiza zamandla omshayeli we-LED
1. Ukushintsha umthombo wamanje ongashintshi
Njengamanje, kusetshenziswa aukushintsha ukunikezwa kwamandlaukuklama isifunda somshayeli we-LED kuyindlela evamile yokuklama evamile.
Okokuqala, kusukela kumbono wayo wokuklama, kusukela ekugcineni kokufaka, ngokuvamile ngokusebenzisa i-i-transformer yakhelwengokwawo, amandla kagesi aphezulu we-AC ezimbonini ehliselwa ku-voltage ephansi (AC-DC), futhi amandla kagesi e-DC azinzile angaphuma ngomjikelezo wesihlungi sokulungisa. Ngaphezu kwalokho, isekethe yesihlungi se-EMI, isifunda sokuvikela ukukhuphuka nombani, isekethe yokuvikela i-electrostatic, i-overvoltage kanye nesekhethi yokuvikela i-undervoltage, njll. iyengezwa, futhi ukusebenza kuhle kakhulu futhi ukwethembeka kuphakeme.
Okwesibili, kunamasekhethi amabili omthombo wamanje wokushintsha njalo, enye iyisekhethi yokuhlukanisa kanti enye iyisekhethi engahlukanisi.
Kusukela egameni,isifunda sokuzihlukanisawenze amabhulokhi athile kwezinye izingxenye ze-high-voltage kuya ku-low-voltage, ngokusebenza kokuphepha okuphezulu, ukuphepha okuphezulu kwesekethe yangaphakathi, kanye nokusebenza kokufakwa kwangaphandle okuba kubi kakhulu. Imfuneko yokuphuma kwesekethe yokuhlukanisa yaseNyakatho Melika ingu-<60Vac.
Okunyeisifunda esingabodwaisongwe ngegobolondo lepulasitiki elivikelayo langaphandle, elingaphephile kangako, kodwa izindleko ngokwemvelo ziphansi kunesekhethi yokuhlukanisa. Zombili izindlela zinezinzuzo zazo kanye nokubi.
Ngakho-ke kusuka kulawa maphuzu amabili, kungabonakala ukuthi ukunikezwa kwamandla okushintsha kuvame ukuba nokusebenza okungcono kokuphepha nokusebenza okuzinzile, okufanelekile ukuba kube okujwayelekile.Ukunikezwa kwamandla komshayeli we-LEDdesign umqondo!
2. Ukunikezwa kwamandla kwedrayivu yomugqa
Okubizwa ngokuthi ulayini wamandla kagesi, njengoba negama liphakamisa, uwumthombo wamandla olayini. Ukunemba, ama-voltages okufaka nawokukhiphayo ayafana ngokuyisisekelo. Isibonelo, amalambu aseNyakatho Melika asebenzisa isixazululo se-IC esiwumugqa, esinokufaka okungu-120V/60HZ kanye nokukhishwayo okungaba ngu-118V ezimeni eziningi.
Kuyabonakala ukuthi umehluko kusuka kuukushintsha ukunikezwa kwamandlaakukhona ukuthi i-voltage iyancipha yi-transformer, kodwa lokhoi-ICs yomugqa owodwa noma eminingi isetshenziselwa ukwahlukanisa amandla kagesi(ama-IC ajwayelekile afaka i-OB5656). Kukhona futhi izingxenye ezimbalwa, ikakhulukazi ama-aluminium substrates, kunamabhodi agqoke ithusi aluhlaza okushintshanisa amandla kagesi. Enye iphuzu ukuthi inamandla aphezulu kanye nokusebenza kahle okuphezulu, futhi ayidingi ama-electrolytic capacitor, anempilo ende kune-ukushintsha ukunikezwa kwamandla.
Nokho, yonke into inezinhlangothi ezimbili. Nakuba isebenza kahle, umphumela wayo ungamandla kagesi aphezulu. Uma umuntu eyithinta, ibeka ukuphila engozini, ngakho ngokuvamile igobolondo lepulasitiki, eliphephile uma liqhathaniswa, kodwa okunzima ukuliqaqa.
3. Isixazululo se-RC sokusuka phansi
Lokho okubizwa nge-RC ukwehliswa phansi empeleniisebenzisa izici zokushaja nokukhipha ama-capacitor ekuphumeni kokushayela kwamanjeukukhanyisa ama-LED. Kulula ukuyiklama, kulula ukuyisebenzisa, futhi iyonga. Kodwa-ke, abangani abacophelelayo bathole ukuthi kulula ukulimaza isifunda ngenxa yobulula baso, futhi kunezici eziningi ezingazinzile.
Ikakhulukazi ehlobo lapho amandla elinganiselwe, ukucisha kukagesi namandla aphinde avuleke njalo kuzodala ukulimala kwesibani. Okukhiphayo kuyafana nalokho kwe-IC yomugqa, futhi i-voltage ephezulu ayihlukanisiwe, ngakho kuyingozi kakhulu ukuyisebenzisa. Nokho, igobolondo layo liyipulasitiki, ngakho-ke uma kuqhathaniswa, ukuphepha kwalo akufani nokushintsha kwamandla kagesi.
Ngakho-ke isimo sayo esijwayelekile sohlelo lokusebenzaamandla aphansiisibani, cishe 5W.
Ngemibuzo yomkhiqizo, sicela uhlole i-ikhasi lomkhiqizo, wamukelekile futhiXhumana nathingemininingwane yokuxhumana engezansi, sizokuphendula kungakapheli iminyaka engama-24.
