Izilumkiso ezilishumi ze-LED Izibane zesitalatoIzibane ze-LED

Izilumkiso ezilishumi ze-LED Street Lights-Izibane zesitalato ze-LED Inani elikhulu lezicelo zezibane zesitalato ze-LED kuluntu lwanamhlanje luye lwadlala indima ebalulekileyo kwinkqubela phambili yobunjineli bokukhanyisa, ngokukodwa imiba emibini yokugcinwa kwamandla kunye nekhabhoni ephantsi yezibane zesitalato ze-LED ziye zenza igalelo elibalulekileyo kuluntu. Makhe sithethe ngenkqubo yokusetyenziswa kwansuku zonke. Izinto ezili-10 ekufuneka izibane zesitalato ze-LED zinikele ingqalelo kuzo. 1. Umbane wokukhanya kwesitrato se-LED kufuneka ube yinto eqhubekayo Iimpawu zezinto zokukhanyisa izibane zesitrato ze-LED zinquma ukuba zichaphazeleka ngokusingqongileyo. Ngokomzekelo, njengoko iqondo lokushisa litshintsha, i-current ye-LED iya kwanda; Ukongeza, i-LED yangoku iya kwanda ngokunyuka kombane. Ukuba umsebenzi wexesha elide udlula umlinganiselo wangoku, uya kunciphisa kakhulu ubomi benkonzo yokukhanya kwesibane se-LED.

I-LED eqhubekayo yangoku kukuqinisekisa ukuba ixabiso langoku lomsebenzi walo lihlala lingatshintshi xa izinto zokusingqongileyo ezifana nobushushu kunye nokutshintsha kombane. 2. Ukuchaneka okuthe gqolo kwangoku kombane wesibane sesitalato se-LED Ukuchaneka okuthe rhoqo kwangoku kokunye kobonelelo lwamandla kwimarike kubi, impazamo inokufikelela ku-±8%, kwaye impazamo eqhubekayo yangoku inkulu kakhulu. Imfuno jikelele ingaphakathi ±3%.

Ngokweskimu soyilo lwe-3%. Ubonelelo lwamandla emveliso kufuneka lulungiswe kakuhle ukuze kuphunyezwe impazamo eyi ±3%. 3. I-voltage esebenzayo ye-LED yesibane sesitalato sombane Ngokuqhelekileyo, i-voltage yokusebenza ekhuthazwayo ye-LEDs yi-3.0-3.5V. Emva kokuvavanya, uninzi lwazo lusebenza kwi-3.2V, ngoko ke i-formula yokubala esekelwe kwi-3.2V inengqiqo ngakumbi.

Amandla ombane ewonke amaso wesibane se-N kuchungechunge = 3.2 * N 4. Yiyiphi eyona nto isebenzayo ngoku ifanelekileyo yombane wesibane sesitalato se-LED? Ngokomzekelo, umlinganiselo osebenzayo we-LED yi-350mA, ezinye iifektri ziyisebenzisa ekuqaleni, kunye noyilo lwe-350mA, eneneni, ubushushu bomsebenzi bunzulu kakhulu phantsi kweli xesha langoku, emva kweemvavanyo ezininzi zokuthelekisa, kulungele ukuyila njenge-320mA. Ukunciphisa ukuveliswa kobushushu, ukuze amandla ombane amaninzi aguqulwe abe ngamandla okukhanya okubonakalayo. 5. Ububanzi be-series-parallel uxhumano kunye nombane obanzi webhodi yamandla yesibane sesitalato se-LED? Ukuze wenze ukukhanya kwesitrato se-LED kusebenze kuluhlu lombane olubanzi ngokwentelekiso lwe-AC85-265V, i-LED series-parallel connection yebhodi yokukhanya ibaluleke kakhulu.

Zama ukungasebenzisi i-voltage ebanzi, inokwahlulwa ibe yi-AC220V, AC110V kangangoko kunokwenzeka, ukuze uqinisekise ukuthembeka konikezelo lwamandla. Ekubeni unikezelo lwamandla lwangoku luhlala luyi-non-yehla-phantsi oluqhubekayo lwangoku lwamandla ombane, xa i-voltage efunekayo i-110V, i-voltage ye-output ayifanele idlule i-70V, kunye nenani lokudibanisa uchungechunge akufanele lidlule i-23.

Oko kukuthi, inani loxhulumaniso lwechungechunge alidluli kwiintambo ze-45. Inani lokudibanisa okuhambelanayo akufanele libe likhulu kakhulu, ngaphandle koko ukusebenza kwangoku kuya kuba kukhulu kakhulu kwaye ukunikezelwa kwamandla kuya kutshisa kakhulu. Kukwakho nesisombululo samandla ombane abanzi, i-APFC imbuyekezo yamandla asebenzayo kukuqala ukusebenzisa i-L6561/7527 ukunyusa i-voltage ukuya kwi-400V, emva koko yehle, elingana nombane otshintshayo kabini.

Le nkqubo isetyenziswa kuphela phantsi kweemeko ezithile. 6. Ukuzihlukanisa / ukungazinzi Ngokuqhelekileyo, ukuba umbane ozimeleyo wenziwa kwi-15W kwaye ufakwe kwi-tube yamandla yesibane sesitalato se-LED, i-transformer inkulu kakhulu kwaye kunzima ukuyifaka. Ngokuqhelekileyo, ukuhlukaniswa kunokufikelela kuphela kwi-15W, kwaye ezo zidlula i-15W zinqabile, kwaye ixabiso libiza kakhulu.

Ngoko ke, umlinganiselo wexabiso lomsebenzi wokuzihlukanisa awukho phezulu. Ngokuqhelekileyo, ukungahlukanisi yinto eqhelekileyo, kwaye umthamo unokwenziwa umncinci, kwaye ubude obuncinane bunokuba yi-8mm. Enyanisweni, akukho ngxaki ukuba amanyathelo okhuseleko lokungakhethi athathwe kakuhle. Ukuba indawo iyavuma, isenokusetyenziswa njengobonelelo lwamandla oluzimeleyo. 7. Umbane wesibane sesitalato se-LED unokuhambelana njani nebhodi yesibane yesibane? Enyanisweni, ukuba ukhetha uxhulumaniso olululo lwe-series-parallel, i-voltage kunye ne-current esetyenziswe kwi-LED nganye iya kufana, kodwa ukunikezelwa kwamandla kuya kuba nokusebenza kakuhle.

Eyona ndlela ilungileyo kukunxibelelana nomenzi wombane kuqala kwaye wenze umthungi. Okanye uvelise owakho umbane. 8. Ukukhanya kwe-LED yesitalato ukusebenza kakuhle kwamandla okufakwayo kuthabatha ixabiso lamandla emveliso, le parameter ibaluleke kakhulu, ixabiso elikhulu, liphantsi ukusebenza kakuhle, oku kuthetha ukuba inxalenye enkulu yamandla egalelo iguqulwa ibe bubushushu kwaye ikhutshwe; ukuba ifakwe kwisibane, iya kuvelisa ubushushu obuphezulu kakhulu, kunye nobushushu obukhutshwa ngumlinganiselo okhanyayo wokusebenza kakuhle kwe-LED yethu, iya kubeka ubushushu obuphezulu. Kwaye ubomi bawo onke amalungu e-elektroniki ngaphakathi konikezelo lwamandla ethu buya kucuthwa njengoko ubushushu bunyuka. Ngoko ukusebenza kakuhle yeyona nto ibalulekileyo emisela ubomi bombane. Eyona nto ibalulekileyo kukuba ukusebenza kakuhle akunakuncipha kakhulu, ngaphandle koko ubushushu obusetyenzisiweyo kumandla ombane buya kuba bukhulu kakhulu.

Ukusebenza kohlobo olungekho lodwa luphezulu kunolo lolo hlobo olulodwa, ngokubanzi ngaphezu kwama-80%. Nangona kunjalo, ukusebenza kakuhle kuhambelana nendlela yokudibanisa ehambelanayo yebhodi yokukhanya. 9. Ukutshatyalaliswa kokushisa komthombo wokukhanya kwesitrato se-LED Eyona nto iphambili yesisombululo sokutshatyalaliswa kobushushu kukuba ubude bokukhanya kwesibane sesitalato se-LED bunokwandiswa kakhulu xa kusetyenziswa phantsi kwemeko yokungagqithisi. Ngokuqhelekileyo, i-alloy ye-aluminium isetyenzisiweyo, ekulula ukuyichitha ubushushu. Oko kukuthi, ukukhanya kwe-LED ukukhanya kwesitrato ubuhlalu kufakwe kwi-aluminium substrate, kwaye indawo yokutshatyalaliswa kobushushu yangaphandle iyandiswa ngokusemandleni. 10. Ukupholisa isibane sesibane sesitalato se-LED Eyona nto iphambili yokutshatyalaliswa kobushushu kukuba amaso ombane wesibane sesitalato se-LED anokwandisa kakhulu ubomi bawo xa esetyenziswa phantsi kwemeko yokungagqithisi. Ngokuqhelekileyo, ii-radiators ze-aluminium alloy zisetyenziselwa, ekulula ukukhupha ukushisa.

Oko kukuthi, ukukhanya kwe-LED ukukhanya kwesitrato ubuhlalu kufakwe kwi-aluminium substrate, kwaye indawo yokutshatyalaliswa kobushushu yangaphandle iyandiswa ngokusemandleni. Ezi zinto zilishumi zingasentla zihlalutye amanqaku aphambili ezibane zesitalato ze-LED ngokweenkcukacha kuthi. Ukusetyenziswa ngokufanelekileyo kuya kuphucula ubomi benkonzo yezibane zesitalato ze-LED kunye nokunciphisa iindleko zokuvelisa. Ndiyakholelwa ukuba nabani na uya kuba nomdla kakhulu.
