Izimfihlo Eziyishumi Ezincane Ze-LED Street Lamp Technology

Iphrojekthi yokukhanyisa imboni yokukhanyisa i-LED ayithonywa nje kuphela imvelo yomhlaba, kodwa futhi nezici zayo ezikhethekile zomkhakha. I-LED street light power supply iyona kanye into ehamba phambili ekuthuthukisweni kwe-LED yamanje. Ngemiklamo ehlobene kubuchwepheshe be-LED, okwamanje kunezixazululo eziningi nezindlela eziyingqayizivele zokuklama. Ake sizibheke ngamunye ngamunye. Kungani ukukhanya kwe-LED emgwaqweni kungashintshi? Izici zezinto zokukhanyisa ze-LED zinquma ukuthi kunomthelela omkhulu emvelweni. Isibonelo, izinguquko zokushisa zikhuphuka, i-current ye-LED izokhula, i-voltage iyanda, futhi i-current ye-LED izokhula. Ukudlula isikhathi eside umsebenzi wamanje olinganisiwe kuzofinyeza kakhulu ubuhlalu besibani se-LED. I-LED engaguquki yamanje iwukuqinisekisa ukuthi inani layo lamanje elisebenzayo aliguquki lapho izici zemvelo ezifana nezinga lokushisa namandla kagesi zishintsha. 2. Ukunikezwa kwamandla kagesi wesibani somgwaqo we-LED Ukunemba kwe-Hengli Ukunemba okuqhubekayo kwamanje emakethe kubi, njengesikimu sodumo emakethe, njengecebo lokusakaza elidumile, iphutha lifinyelela ±8%, iphutha lamanje eliqhubekayo likhulu kakhulu. Kudingeka ngokujwayele ±3%. Ngokohlelo lwe-design 3%. Ukunikezwa kwamandla okukhiqiza kufanele kulungiswe kahle ngaphambi kokuba kufinyelelwe ±3% i-error. 3. Amandla kagesi okusebenza kagesi wokukhanya komgwaqo we-LED ngokuvamile angu-3.0-3.5V. Ngemuva kokuhlolwa, iningi labo lisebenza ku-3.2V, ngakho-ke ukubala kwe-3.2V kunengqondo kakhulu. Isamba se-voltage yobuhlalu besibani ochungechungeni = 3.2* N4, amandla kagesi wesibani somgwaqo we-LED afaneleka kakhulu, njengesilinganiso samanje sokusebenza se-LED 350 mAh, ezinye izimboni zisetshenziswa ekuqaleni, kanye nomklamo 350 mAh. Eqinisweni, umsebenzi ngaphansi kwalesi samanje ushisa kakhulu. Ngemuva kokuhlolwa okuqhathanisayo okuningi, kuhle ukuklanywa njengo-320 mAh. Zama ukunciphisa ukushisa kwezinwele, ukuze ugesi owengeziwe ube amandla okukhanya abonakalayo. 5. Lubanzi kangakanani uchungechunge nobubanzi be-voltage yebhodi likagesi wesibani somgwaqo we-LED? Ukwenza ukukhanya kokukhanya komgwaqo we-LED kusebenze ebangeni lokufakwa kwamandla kagesi, i-AC85-265V, uchungechunge lwe-LED nendlela yokuxhuma yebhodi lokukhanya kubaluleke kakhulu. Zama ukungasebenzisi i-voltage ebanzi ngangokunokwenzeka, ingahlukaniswa ibe yi-AC220V, futhi i-AC110V ihlelwa ngangokunokwenzeka, ukuze uqinisekise ukwethembeka kokunikezwa kwamandla. Njengoba ugesi wamanje ngokuvamile uwumthombo wamandla wamanje ongahlukanisi -i-voltage ongashintshi, lapho i-voltage ingu-110V, i-voltage ephumayo ingeqi ku-70V, futhi inani lochungechunge alidluli izintambo ezingu-23. Lapho i-voltage yokufaka engu-220V, i-voltage ephumayo ingafinyelela ku-156V. Ngamanye amazwi, inani lochungechunge alidluli uchungechunge lwama-45. Ungabi nenombolo ehambisana kakhulu, ngaphandle kwalokho ukusebenza kwamanje kukhulu kakhulu, futhi ukunikezwa kwamandla kushisa kakhulu. Kukhona futhi isisombululo se-wide -voltage. Isinxephezelo samandla omthombo we-APFC ukusebenzisa i-L6561/7527 ukunyusa i-voltage ibe ngu-400V, bese unciphisa i-voltage. Lesi sixazululo sisetshenziswa kuphela ngaphansi kwezimo ezithile. I-6, i-isolation/non-isolation jikelele yokuhlukaniswa kwamandla, uma yenziwe ku-15W, ifakwe ku-LED street light power pipe, i-transformer yayo inkulu kakhulu, kunzima ukuyifaka. Ngokuyinhloko kuncike esakhiweni sesikhala kuncike esimweni esithile. Ngokuvamile, ukuhlukaniswa kungafinyelela kuphela i-15W, ngaphansi kuka-15W, futhi intengo ibiza kakhulu. Ngakho-ke, ukuphumelela kwezindleko zokuzihlukanisa akuphezulu. Ngokuvamile, ama-akhawunti okungewona awodwa abangela ukwanda okujwayelekile, umthamo ungaba mncane, futhi ubuncane bungaba ngu-8 mm ukuphakama. Eqinisweni, izinyathelo zokuphepha ezingahlukanisiwe ziyenziwa. Isikhala esivumelayo singasetshenziswa futhi njengendawo yokuhlukanisa ugesi. 7. Ukunikezwa kwamandla okukhanya komgwaqo we-LED kungafaniswa kanjani nebhodi lobuhlalu besibani? Amanye amakhasimende aqala ngokuklama ibhodi lesibani, bese ethola ugesi. Kunzima ukuthola ugesi ofanelekile, noma owamanje mkhulu kakhulu, futhi i-voltage incane kakhulu (njenge-7x1wi > 350mA, noma i-V25V), umphumela uwukushisa okukhulu, ukusebenza kahle okuphansi, noma ububanzi bevoltheji yokufaka enganele. Eqinisweni, ukukhetha indlela engcono kakhulu yokuxhuma nge-LED ngayinye kuyafana, kodwa umphumela wokuphakelwa kwamandla ungenza ukusebenza okuhle kakhulu. Indlela engcono kakhulu yokuxhumana nabakhiqizi bamandla kuqala futhi yenziwe ngomthungi. Noma ikhiqiza amandla kagesi. 8. Ama-skewers e-LED kanye ne-PFC power factor areolation input AC220V high -voltage end electrolytic capacitance umthamo ngokuvamile amandla okokufaka 1W = 1UF, AC110V1W = 2UF okwamanje inamacala amathathu okuphakelwa kukagesi PFC: eyodwa ayinayo i-PFC ngaphandle kwesinxephezelo sesici samandla Kumasekhethi azinikele, i Inani le-PF ngokuvamile lizungeze u-0.65; okwesibili i-passive power factor compensation PFC circuit, okungukuthi, ukukhanya kwesinxephezelo sesici samandla angenzi lutho, kanye nebhodi lesifunda sokugeleza okwamanje elinokwethenjelwa okungcono kakhulu, PF PF, PF Inani ngokuvamile lizungeze u-0.92; izinhlobo ezintathu zesekethe esebenzayo ye-7527/6561 nazo zisetshenziswa, okungukuthi, isinxephezelo sesici samandla omthombo, esibizwa nge-AC220V kusekethe ye-APFC, i-AC110V ingasebenzisa ama-electrolytic capacitors womthamo ofanayo, khetha 1W = 1W = 1.5uf. Inani le-PF lingafinyelela ku-0.99, kodwa izindleko zalesi sixazululo zimbi kakhulu kunesixazululo sesibili. Ngakho isixazululo sesibili sisetshenziswa kakhulu. Kusekhethi ye-PFC engenzi lutho: eyaziwa nangokuthi isekethe ye-Chan -type PFC, ububanzi bayo be-DC yokusebenza kagesi buyingxenye yokuphakama kwamandla kagesi we-AC. Uma okokufaka kungu-220V, ukuphakama kwayo kungu-220 * 1.414 = 312V, kanti ingxenye ye-voltage ephezulu ingu-156V. Ngakho-ke, inani lobuhlalu bamandla okukhanya komgwaqo we-LED lifika kuchungechunge lwama-45 ngezansi. Ngakho-ke, uma ufuna ukuthola izici eziningi zamandla, inani lezibani akufanele libe lincane kakhulu, kungenjalo isimo esihle kakhulu sokusebenza ngeke sizuzwe. Amandla okunikezwa kwamandla kumele ahlangabezane namandla okukhiphayo. Lapho amandla amanje asebenzayo ezingxenye ze-elekthronikhi eba mncane ebangeni lokusebenza likagesi olinganiselwe, isikhathi sokuphila siba side, isikhathi sokuphila siyoba sifushane. Ubuhlalu bamandla okukhanya komgwaqo we-LED buzwela kakhulu kunani lokuxhumana. Ukuphakama kwenani lokuxhumana, kubi nakakhulu ukunethezeka kokukhanya. Ngokuvamile, ama-electrolytic capacitor kufanele asetshenziselwe ukugcina i-voltage, futhi i-voltage ye-voltage yokuphela kokuphumayo isetshenziswa ngangokunokwenzeka. Umthamo we-electrolytic capacitance end of the low voltage akumele ube mncane kakhulu. I-non-isolation end yokukhetha i-electrolytic capacitance ephezulu-voltage iyafana nokuhlukaniswa, futhi i-output-end capacitor ikhetha i-1UF
