Izinyathelo Eziyishumi Zokuqapha Izibani Ze-LED StreetsLED Street Lights

Izinyathelo Eziyishumi Zokuqapha Izibani Ze-LED Street-Izibani Zomgwaqo ze-LED Inani elikhulu lezicelo zezibani zemigwaqo ye-LED emphakathini wanamuhla liye labamba iqhaza elibalulekile ekuqhubekeleni phambili kobunjiniyela bokukhanyisa, ikakhulukazi izici ezimbili zokonga ugesi kanye nekhabhoni ephansi yezibani ze-LED zomgwaqo ziye zenza iminikelo ebalulekile emphakathini. Ake sikhulume ngenqubo yokusetshenziswa kwansuku zonke. Izinto eziyi-10 okufanele izibani zasemgwaqweni ze-LED zinake. 1. Ugesi wokukhanya komgwaqo we-LED kufanele ube wamanje njalo Izimpawu zezinto ezikhanyayo zezibani zasemgwaqweni ze-LED zinquma ukuthi zithintwa imvelo. Isibonelo, njengoba izinga lokushisa lishintsha, i-current ye-LED izokhula; ngaphezu kwalokho, i-current ye-LED izophinde ikhule ngokunyuka kwe-voltage. Uma umsebenzi wesikhathi eside udlula okwamanje olinganisiwe, uzonciphisa kakhulu impilo yenkonzo yobuhlalu besibani se-LED.

I-LED engaguquki yamanje iwukuqinisekisa ukuthi inani lamanje lomsebenzi walo lihlala lingashintshile lapho izici zemvelo ezifana nezinga lokushisa kanye nokushintsha kwamandla kagesi. 2. Ukunemba kwamanje okungaguquguquki kokuphakelwa kwamandla okukhanya komgwaqo we-LED Ukunemba okuqhubekayo kwamanje kwamanye amandla kagesi emakethe kubi, iphutha lingase lifinyelele ku-±8%, futhi iphutha lamanje eliqhubekayo likhulu kakhulu. Isidingo esijwayelekile singaphakathi kuka-±3%.

Ngokusho kohlelo lokuklama lwe-3%. Ukunikezwa kwamandla okukhiqiza kumele kucushwe kahle ukuze kuzuzwe iphutha elingu-±3%. 3. Amandla kagesi okusebenza kagesi wokukhanya komgwaqo we-LED Ngokuvamile, i-voltage enconywayo yokusebenza yama-LED ngu-3.0-3.5V. Ngemva kokuhlola, iningi lazo lisebenza ku-3.2V, ngakho ifomula yokubala esekelwe ku-3.2V inengqondo kakhulu.

Isamba sikagesi sobuhlalu besibani esingu-N ochungechungeni = 3.2*N 4. Iyiphi inkathi yokusebenza efaneleke kakhulu yomthombo wamandla wokukhanya komgwaqo we-LED? Isibonelo, ukusebenza okulinganiselwe kwe-LED kungu-350mA, amanye amafekthri ayisebenzisa ekuqaleni, futhi aklame i-350mA, empeleni, ukushisa komsebenzi kubi kakhulu ngaphansi kwalokhu kwamanje, ngemva kokuhlolwa okuningi kokuqhathanisa, kuhle ukuyiklama njenge-320mA . Nciphisa ukukhiqizwa kokushisa, ukuze amandla amaningi kagesi aguqulwe abe amandla okukhanya abonakalayo. 5. Kubanzi kangakanani uchungechunge-parallel uxhumano kanye voltage ebanzi we LED street isibani ibhodi amandla? Ukuze kwenziwe ukukhanya kokukhanya komgwaqo we-LED kusebenze ebangeni lamandla kagesi okufakwayo abanzi kakhulu we-AC85-265V, uchungechunge lwe-LED lokuxhuma okuhambisanayo kwebhodi lokukhanya kubaluleke kakhulu.

Zama ukungasebenzisi i-voltage ebanzi, ingahlukaniswa ibe yi-AC220V, AC110V ngangokunokwenzeka, ukuze uqinisekise ukuthembeka kokunikezwa kwamandla. Njengoba ukunikezwa kwamandla kwamanje ngokuvamile kuwukuphuma kwamandla okuhlala njalo okungeyona okukodwa okuya phansi, lapho i-voltage edingekayo ingu-110V, i-voltage ephumayo akufanele idlule i-70V, futhi inani lokuxhunywa kochungechunge akufanele lidlule i-23. Uma i-voltage yokufaka ingu-220V, i-voltage ephumayo ingafinyelela ku-156V.

Okusho ukuthi, inani lokuxhuma kochungechunge alidluli izintambo ezingu-45. Inombolo yokuxhuma okuhambisanayo akufanele ibe nkulu kakhulu, ngaphandle kwalokho ukusebenza kwamanje kuzoba kukhulu kakhulu futhi ukunikezwa kwamandla kuzoshisa kakhulu. Kukhona nesixazululo se-voltage ebanzi, isinxephezelo samandla asebenzayo i-APFC esokuqala sisebenzise i-L6561/7527 ukunyusa i-voltage ibe ngu-400V, bese wehla, okulingana nokushintshwa kwamandla okubili.

Lolu hlelo lusetshenziswa kuphela ngaphansi kwezimo ezithile. 6. Ukuzihlukanisa/ukungahlukaniswa Ngokujwayelekile, uma ukunikezwa kwamandla okuhlukanisiwe kwenziwa ku-15W futhi kufakwe ku-tube yamandla yesibani somgwaqo we-LED, i-transformer inkulu kakhulu futhi kunzima ukuyifaka. Ngokuyinhloko incike esakhiweni sesikhala futhi incike esimweni esithile. Ngokuvamile, ukuhlukaniswa kungafinyelela ku-15W kuphela, futhi lezo ezedlula i-15W azivamile, futhi intengo ibiza kakhulu.

Ngakho-ke, isilinganiso sokusebenza kwentengo sokuzihlukanisa asiphezulu. Ngokuvamile, ukungahlukanisi kuyinto evamile, futhi umthamo ungenziwa ube mncane, futhi ubude obuncane bungaba ngu-8mm. Eqinisweni, ayikho inkinga uma izinyathelo zokuphepha zokungahlukanisi zithathwa kahle. Uma isikhala sivuma, singasetshenziswa futhi njengendawo yokuphehla ugesi eyodwa. 7. Ugesi wesibani somgwaqo we-LED ungafanelana kanjani nebhodi lobuhlalu besibani? Eqinisweni, uma ukhetha uxhumano olungcono kakhulu lwe-series-parallel, i-voltage kanye namanje okusetshenziswe ku-LED ngayinye kuzofana, kodwa ukunikezwa kwamandla kuzoba nokusebenza okungcono kakhulu.

Indlela engcono kakhulu ukuxhumana nomkhiqizi wokuphakela amandla kuqala bese wenza owenziwe ngomthungi. Noma khiqiza owakho ugesi. 8. Ukusebenza kahle kwamandla okukhanya komgwaqo we-LED Amandla okufakwayo asusa inani lamandla okukhiphayo, le pharamitha ibaluleke kakhulu, inani elikhulu, linciphisa ukusebenza kahle, okusho ukuthi ingxenye enkulu yamandla okufakwayo iguqulwa ibe ukushisa futhi ikhishwe; uma ifakwe esibani, izokhiqiza izinga lokushisa eliphezulu kakhulu, kanye nokushisa okukhishwa isilinganiso esikhanyayo se-LED yethu, kuzobeka izinga lokushisa eliphakeme kakhulu. Futhi impilo yazo zonke izingxenye ze-elekthronikhi ezingaphakathi kwamandla ethu azofinyezwa njengoba izinga lokushisa likhuphuka. Ngakho ukusebenza kahle kuyisici esibaluleke kakhulu esinquma impilo yokunikezwa kwamandla. Isici esibalulekile ukuthi ukusebenza kahle akukwazi ukuba phansi kakhulu, ngaphandle kwalokho ukushisa okudliwe ekunikezeni amandla kuzoba kukhulu kakhulu.

Ukusebenza kahle kohlobo olungahlukanisiwe kuphakeme kunohlobo olulodwa, ngokuvamile ngaphezu kwama-80%. Kodwa-ke, ukusebenza kahle kuhlobene nendlela yokuxhuma ehambisanayo yebhodi lokukhanya. 9. Ukushisa komthombo wokukhanya komgwaqo we-LED Isici esiyinhloko sesisombululo sokushisa ukushisa ukuthi isikhathi sokuphila sobuhlalu besibani somgwaqo we-LED singanwetshwa kakhulu uma sisetshenziswa ngaphansi kwesimo sokungashisi ngokweqile. Ngokuvamile, i-aluminium alloy isetshenziswa, okulula ukukhipha ukushisa. Okusho ukuthi, ubuhlalu bamandla okukhanya komgwaqo we-LED bunamathiselwe ku-aluminium substrate, futhi indawo yokukhipha ukushisa yangaphandle ikhuliswa ngangokunokwenzeka. 10. Ukupholisa amandla isibani somgwaqo we-LED Isici esiyinhloko sokuqeda ukushisa ukuthi ubuhlalu bamandla wesibani somgwaqo we-LED bungandisa kakhulu impilo yabo lapho busetshenziswa ngaphansi kwesimo sokungashisi ngokweqile. Ngokuvamile, kusetshenziswa ama-radiators e-aluminium alloy, okulula ukukhipha ukushisa.

Okusho ukuthi, ubuhlalu bamandla okukhanya komgwaqo we-LED bunamathiselwe ku-aluminium substrate, futhi indawo yokukhipha ukushisa yangaphandle ikhuliswa ngangokunokwenzeka. Lezi zinto eziyishumi ezingenhla zihlaziye amaphuzu abalulekile amalambu e-LED street ngokuningiliziwe kithi. Ukusetshenziswa okunengqondo kuzothuthukisa impilo yesevisi yezibani zomgwaqo ze-LED futhi kunciphise izindleko zokukhiqiza. Ngikholelwa ukuthi noma ubani uzoba nesithakazelo esikhulu.
