Uninzi lweenjineli ezisebenza kwishishiniukutshintsha unikezelo lwamandlaishishinibayabandakanyekaUmbane womqhubi we-LEDuyilo. Uninzi lweenkampani zineentlobo ezintathu eziphambili zoyilo lonikezelo lwamandla omqhubi:
Ekuqaleni. Intshayelelo kunye neempawu zeAmandla omqhubi we-LED
1. Intshayelelo yeAmandla omqhubi we-LED
Amandla omqhubi we-LED abhekisa kumandla aguqulwa abe sisibane se-LED ngokusebenzisa i-voltage converter (efana ne-AC-DC).
Ngokuqhelekileyo, igalelo lii-high-voltage industrial frequency ACkwiimeko ezininzi, nto leyo esiyibiza ngokuba ngumbane oyintloko. umbane ongundoqo welizwe lam yi-220V/50HZ, kwaye umbane oyintloko waseMntla Melika yi-120V/60HZ; okwesibini, kukhoi-high-voltage kunye ne-low-voltage DC, njenge-12V, 24V kunye ne-36V, kwaye kukho i-low-voltage high-frequency AC, kanye njengei-electronic transformersisebenzisa siya kukhupha i-voltage ehambelanayo.
2. Ubume bangoku kunye neempawu zeUmbane womqhubi we-LED
(1)Ukuthembeka okuphezulu, Ngokuqhelekileyo, iwaranti yezibane zaseMntla Melika inokufikelela kwiminyaka emi-5, okulungileyo.
(2)Ukusebenza okuphezulu, Ukusebenzisaukutshintsha unikezelo lwamandlaokanye unikezelo lwamandla ombane, ukusebenza kakuhle kwe-75 ~ 80% kuphezulu kakhulu.
(3)Umba wamandla aphezulu, ngokuqhelekileyo ukufikelela ngaphezu kwe-0.9, oku kuthetha ukuba izixhobo zenza umsebenzi omncinci ongenamsebenzi, zisebenzisa amandla ngokufanelekileyo, kwaye izibane ziya kuhlala ixesha elide.
(4) Inokhuseleko olusebenzayo olufana nokukhuselwa kokunyuka, ukugqithiswa kunye nokungabikho kombane.
(5) Inemisebenzi yokumelana nothuli kunye namanzi, njengenqanaba le-IP44.
(6) Inemigaqo yokhuseleko kunye nokusebenza kokuhambelana kwe-electromagnetic.
(7) Abaqhubi abathathu abaqhelekileyo baya kuxoxwa ngezantsi.
Isibini. Ezintathu eziqhelekileyoIzixhobo zombane zomqhubi we-LED
1. Ukutshintsha umthombo wangoku rhoqo
Okwangoku, usebenzisa aukutshintsha unikezelo lwamandlaukuyila isekethe yomqhubi we-LED yeyona ndlela iqhelekileyo yoyilo oluqhelekileyo.
Okokuqala, ukusuka kwingcamango yoyilo, ukusuka ekupheleni kwegalelo, ngokubanzi ngei-transformer yenziwengokwawo, amandla ombane aphezulu we-AC athotywa ezantsi ukuya kwi-voltage ephantsi (AC-DC), kwaye i-voltage ye-DC ezinzileyo inokukhutshwa ngesekethe yokucoca isihluzi. Ukongeza, i-EMI filter circuit, i-surge and lighting protection circuit, i-electrostatic protection circuit, i-overvoltage kunye ne-undervoltage protection circuit, njl njl.
Okwesibini, kukho iisekethe ezimbini zokutshintsha komthombo oqhubekayo wangoku, enye yisekethe yokwahlula kwaye enye yisekethe yokungahlukanisi.
Ukusuka kwigama,isekethe yokwahlulawenze iibhloko ezithile kwiindawo ezine-voltage eziphakamileyo ukuya kwi-low-voltage, ngokusebenza kokhuseleko oluphezulu, ukhuseleko oluphezulu lwesekethe yangaphakathi, kunye nokusebenza kakubi kancinci kwangaphandle kokugquma. Imfuno yemveliso yesekethe yokwahlula yaseMntla Melika ngu <60Vac.
Enyeisekethe engekho yodwaisongelwe kwiqokobhe leplastiki elikhuselayo langaphandle, elingakhuselekanga kangako, kodwa ixabiso liphantsi ngokwendalo kunesekethe yokuzahlula. Zombini ezi ndlela zineengenelo kunye nezingeloncedo zazo.
Ngoko ke kula manqaku mabini, kunokubonwa ukuba ukunikezelwa kwamandla okutshintsha kudla ukuba nokhuseleko olungcono kunye nokusebenza okuzinzileyo, okufanelekile ukuba ibe yinto eqhelekileyo.Umbane womqhubi we-LEDingcamango yoyilo!
2. Unikezelo lwamandla okuqhuba umgca
Into ebizwa ngokuba yi-linear power supply, njengoko igama libonisa, ngumbane wombane. Ukuchaneka, igalelo kunye neziphumo zombane ziyafana. Ngokomzekelo, izibane zaseNyakatho Melika zisebenzisa isisombululo se-IC esicacileyo, kunye negalelo le-120V / 60HZ kunye nesiphumo malunga ne-118V kwiimeko ezininzi.
Kuya kubonakala ukuba umahluko ukusuka kwiukutshintsha unikezelo lwamandlaAkunjalo ukuba i-voltage iyancitshiswa yi-transformer, kodwa loo ntoi-ICs enye okanye ezininzi zisetyenziselwa ukwahlula amandla ombane(ii-IC eziqhelekileyo ziquka i-OB5656). Kukwakho amacandelo ambalwa ngokwentelekiso, ubukhulu becala i-aluminiyam substrates, kuneebhodi ezigqunywe ngobhedu eziluhlaza zonikezelo lwamandla okutshintsha. Enye ingongoma kukuba inamandla amakhulu kunye nokusebenza kakuhle, kwaye ayifuni i-electrolytic capacitors, enobomi obude kunoko.ukutshintsha unikezelo lwamandla.
Nangona kunjalo, yonke into inamacala amabini. Nangona isebenza kakuhle, imveliso yayo inamandla ombane aphezulu. Xa umntu eyichukumisa, ibeka ubomi esichengeni, ngoko ke iqokobhe leplastiki ngokubanzi, elikhuselekile noko, kodwa kunzima ukuliqhawula.
3. Isisombululo se-RC sokuhla
Okubizwa ngokuba yi-RC ukuhla-phantsi ngokweneneusebenzisa ukutshaja kunye nokukhupha iimpawu ze-capacitors kwimveliso yokuqhuba ngokuukukhanyisa ii-LEDs. Kulula ukuyilwa, kulula ukuyisebenzisa, kwaye iyonga. Nangona kunjalo, abahlobo abanononophelo baye bafumanisa ukuba kulula ukulimaza isiphaluka ngenxa yokulula kwayo, kwaye kukho izinto ezininzi ezingazinzanga.
Ingakumbi ehlotyeni xa amandla enqongophele, ukucima kombane kunye nombane olayite rhoqo kuya kubangela umonakalo kwisibane. Imveliso yayo iyafana ne-IC yomgca, kwaye i-voltage ephezulu ayiyedwanga, ngoko kuyingozi kakhulu ukuyisebenzisa. Nangona kunjalo, iqokobhe layo yiplastiki, ngoko ke xa sithelekisa, ukhuseleko lwayo alulunganga njengolo lombane wokutshintsha.
Ke imeko yayo yesicelo ngokubanziamandla aphantsiisibane, malunga ne-5W.
Ngemibuzo yemveliso, nceda ujonge iiphepha lemveliso, nawe wamkelekile ukubaQhagamshelana nathingokusebenzisa iinkcukacha zoqhagamshelwano ezingezantsi, siya kukuphendula phakathi kwama-24.
