Ukutyhubela iminyaka yokusebenza kunye nabavelisi be-luminaire, sihlala sivakalelwa kukuba abavelisi be-luminaire bayathandabuza ukuthenga izixhobo zombane ezingcono ze-LED.Ngokuchasene noko, abazi ukuba bahlukanise njani umbane othengiweyo we-LED, kwaye baxhalabile malunga nokuba bahlawule ixabiso eliphezulu lonikezelo lwamandla oluphantsi lwe-LED.Ngoko ke, njengomvelisi wokukhanyisa, kunzima ukuphendula ukuthengwa kombane we-LED.Ngenxa yokuba umgangatho wombane wokutshintsha kunzima ukuwujonga, sele ukhulile iiyure ezi-4 kwiplanti yayo yokucwangcisa, kwaye abanye baneminyaka engama-24-72 iiyure.Nangona kunjalo, le mveliso yakudala ihlala ijikeleze i-5% okanye ngaphezulu phakathi kweenyanga ezi-3-6 zokuziswa.Ngokuqhelekileyo, kwiimeko ezimbi ngolo hlobo, abavelisi be-luminaire bayahlupheka, babe ngabathengi, kwaye balahlekelwe ngabathengi.
Kuthekani ngokuthatha umgangatho wobonelelo lwamandla e-LED?Sinokuyichonga kule miba ilandelayo:
Ekuqaleni:tyhala itshiphu yokucubungula-IC.
Umxholo ophambili wokunikezelwa kwamandla okuqhuba yisekethe edibeneyo, kwaye izibonelelo kunye nokungonakali kwesekethe edibeneyo inokuchaphazela ngokuthe ngqo zonke izixhobo zokutshintsha umbane.Iisekethe ezidibeneyo zomqhubi weefektri ezinkulu zipakishwe kwiifektri zokupakisha ezinkulu kunye neziphakathi;Itekhnoloji edityanisiweyo yesekethe yomqhubi weefektri ezincinci zokucwangcisa kukukopa kwangoko uyilo lwesikimu sokukhuthaza kwiifektri ezinkulu, kwaye ufumane ukupakishwa kweefektri zokupakisha ezincinci naphakathi, ezingenakuqinisekisa ngokwesiqhelo ukuhambelana kweesekethe ezidibeneyo zebhetshi.kunye nokuthembeka, okukhokelela ekubeni amandla okuqhuba angasebenzi ngaphandle kwesizathu emva kwexesha lokusetyenziswa.Ngoko ke, isiphaluka esidibeneyo kumbane we-LED wenqaba ukupholiswa, okulungele umenzi wesibane ukuba abambe isicwangciso sesiphaluka esidibeneyo kwaye abale iindleko zokunyusa, ukwenzela ukuba kuqinisekiswe ixabiso elisebenzayo lemveliso yombane wokutshintsha.
Isibini:Umtshintshi.
Iprosesa esebenzayo inokuthathwa njengeziko le-nerve yengqondo yomntu otshintshela unikezelo lwamandla, ngelixa amandla aphumayo kunye nokumelana nokushisa okuphezulu kunqunywe yi-transformer.Abaguquli bathatha i-AC yangoku-amandla ombane-amandla e-DC, kunye namandla angaphezulu kwekinetic anokugcwalisa umatshini.Umxholo ophambili we-transformer ngundoqo kunye nephakheji yocingo.
Umgangatho we-core ungundoqo kwi-transformer, kodwa njengobumbi, akulula ukuchonga.Ukuchongwa kwenkangeleko elula kukuba: inkangeleko ibukhali, ixinene kwaye iqaqambile, kwaye icala elingasemva likhazimlisiwe kwaye i-exhaust port iyimveliso elungileyo.Okwangoku, i-core magnetic esetyenziswa yi-Shanghai Nuoyi yi-PC44 ye-magnetic core, esetyenziselwa ukwenza i-mold, eqinisekisa ukusebenza okuphezulu kokunikezelwa kwamandla okutshintsha.
Iphakheji yocingo yenziwe nge-copper core wire winding.Umgangatho wemveliso yocingo oluphambili lobhedu yinxalenye ebalulekileyo yobomi benkonzo ye-reaction transformer.Iintambo ze-aluminiyam ezifakwe ngobhedu ezinobungakanani obufanayo ziyi-1/4 ixabiso leentambo zobhedu ezibomvu.Ngenxa yezizathu zeendleko kunye noxinzelelo lokusebenza, abavelisi be-transformer bahlala bexuba i-transformers kunye ne-copper clad aluminium wraps.Emva koko, xa ubushushu be-transformer bukhuphuka, umonakalo awusebenzi, unikezela umbane wokutshintsha kunye nokukhanya konke kungasebenzi.Ngenxa yoko, uninzi lwezixhobo zokukhanyisa, ngakumbi ezo zinezixhobo zombane ezitshintshiweyo, zihlala zihla zinyuka emva kweenyanga ezi-6 zokuhanjiswa.Indlela yokwahlula ukuba intsimbi yobhedu ilucingo olubomvu okanye i-aluminiyam yobhedu?Sebenzisa i-lighter ukukhanyisa kwaye ngokukhawuleza utshise i-aluminium ene-copper clad.Iyakwazi ukulinganisa ngokuchanekileyo ixabiso lokumelana nekhoyili ye-solenoid.
Isithathu:i-electrolytic capacitors kunye ne-chip ceramic capacitors.
Sonke siyazi ukuba sonke siyawazi umgangatho kunye nobomi benkonzo ye-electrolytic capacitors, kwaye sonke siyithatha ngokungathí sina.Nangona kunjalo, sihlala singayijongi imimiselo yomgangatho wemveliso yokuthumela ngaphandle ii-capacitors.Enyanisweni, ubomi be-capacitor ephumayo buyingozi kakhulu kubomi bokunikezelwa kwamandla okutshintsha.I-frequency yokusebenza yokutshintsha kwamandla kwi-lead-out ekupheleni ifikelela kumaxesha e-6,000 ngesibini, okubangelwa ukwanda kokumelana nokusinda kwe-capacitor kunye nokuveliswa kweekhemikhali ezifana nokungcola.Ekugqibeleni, i-electrolyte yebhetri ye-lithium iyatshisa kwaye iqhume.Kunconywa kakhulu ukuthumela i-electrolytic capacitors: khetha indlela ekhethekileyo ye-electrolytic ye-LED, kwaye imodeli yenkcazo jikelele iqala ukusuka ku-L. Kweli nqanaba, iindlela zethu zokuthumela ngaphandle kwe-electrolytic zonke ii-capacitors ze-electrolytic kunye nobomi benkonzo ephezulu ye-Aihua.
I-Ceramic capacitors: Izinto eziphathekayo zihlukaniswe zibe yi-X7R, i-X5R kunye ne-Y5V, kwaye i-capacitance ethile ye-Y5V inokufikelela kuphela kwi-1/10 yexabiso elithile, kwaye ixabiso eliqhelekileyo le-capacitance libhekisela kuphela kwi-volts eyi-0 ngexesha lokusebenza.Ke ngoko, oku kuxhathisa kuncinci kunye nokukhethwa kakubi kuya kukhokelela kumahluko weendleko, ukunciphisa kakhulu ubomi benkonzo yokunikezelwa kwamandla okutshintsha.
Isine:umgaqo wesekethe kunye nendlela welding yokutshintsha iimveliso zonikezelo lwamandla.
Ukwahlula umgangatho weskimu soyilo: Ukongeza kwimbono yobuchwephesha bobugcisa, inokuphinda yahlulwe ngokweendlela ezithile ezibonwayo, njengokubekeka okufanelekileyo kwamacandelo, ukucoceka, umoya olungeleleneyo, i-welding eqaqambileyo, kunye nokuphakama okucacileyo.Igcisa elilungileyo alityekeleli kuyilo olugqwidizayo.Kwi-wiring, i-handcrafting kunye namacandelo nawo abonakalisa ukungabikho okukhulu kwamandla obugcisa.
Indlela ye-welding: i-welding manual kunye ne-peak welding process.Njengoko sonke siyazi, umgangatho wenkqubo ye-welding ye-automation kufuneka ibe phezulu kune-welding manual.Indlela yokuchonga: nokuba kukho iglu ebomvu ngasemva (inkqubo yokuncedisa i-solder paste + i-welding fixture yombane inokugqiba i-peak welding, kodwa ixabiso lokulungisa liphezulu kakhulu).
Isixhobo sokuhlola ukuwelda indawo ye-SMD: AOI.Kwikhonkco le-SMD, isibonelelo sinokujonga imeko ye-desoldering, i-solder yobuxoki, kunye neendawo ezingekhoyo.
Ngeli nqanaba, isibane sokukhanyisa siya kubetha emva kwexesha lokusetyenziswa, okubangelwa ngokukodwa ukuthengiswa kombane wokutshintsha okanye ubuhlalu besibane se-LED.Ukuhlolwa kwe-desoldering yale mveliso akulula ukudlula ukuhlolwa kokuguga, ngoko ke kuyimfuneko ukusebenzisa i-AOI ukujonga umgangatho we-patch we-switching power supply.
Isihlanu:Jonga iiracks zokwaluphala kunye namagumbi okuguga obushushu aphezulu ngobuninzi bokutshintsha iimveliso zombane.
Nokuba zilunge kangakanani na izinto ezikrwada kunye nemveliso kwimathiriyeli ekrwada kunye neemveliso zamandla emveliso, okanye ukwaluphala kufuneka kuhlolwe.Kunzima ukubeka iliso kwiingxelo zokuhlola ezingenayo zamacandelo e-elektroniki kunye nabaguquli bamandla.Kuphela ngokuguga konikezelo lwamandla okutshintsha kunye nokuhlolwa kwesampulu yobushushu obuphezulu begumbi lobushushu obuphezulu obuqhubekayo, ngaba ukuthembeka komgangatho wokutshintshela umbane kunye nokuba izinto eziluhlaza zinemingcipheko yokhuseleko zinokujongwa.
Isiphumo senani elikhulu lokuhlolwa kwesampulu eqhubekayo yobushushu obuphezulu: Ukungasebenzi kokutshintsha kombane kwesi sigaba kuphakathi kwewaka ukuya kwelinye ipesenti, kwaye oku kungasebenzi kuya kufumaneka kuphela xa amawaka eqhubekayo yokuguga okuphezulu.
Igumbi eliqhubekayo lobushushu obuphezulu linokulinganisa indawo yendalo enzima apho umbane wokutshintsha usebenza.Ukuhlolwa kwesampulu phantsi kwemigangatho engqongqo kunokuveza inani elikhulu leengxaki ezifana nezikimu zokuyila ezingezizo ezenzululwazi, imathiriyeli ekrwada ehlwempuzekileyo, izixhobo zokukhanyisa ezingasebenziyo, kunye neempembelelo zezaphuli zesekethe eziphezulu zombane.
Ukuguga kwexesha elide kwiqondo lobushushu begumbi: khetha ukusilela okungahleliweyo njengokudilizwa, ukuvuza kwamalungu, impembelelo, njl. njl., hluza ukungasebenzi kakuhle kwamacandelo, kwaye unciphise ngokufanelekileyo izinga lokungaphumeleli kwemveliso egqityiweyo (1% ukuya kwi-1/1000) .
Kwiqondo lobushushu begumbi, ukuguga kudla oomatshini abaninzi abaguga, izixhobo kunye nabasebenzi.Yonke imihla, i-100,000 yezityalo ezilungisayo zicima kwaye zicime umbane.Oomatshini bokuguga kunye nezixhobo zigubungela indawo yeemitha ezingama-square ezingama-500, ezinezikhundla ezingaphezulu kwe-10,000 zokuguga, kwaye ukuguga komgca wemveliso kugqityiwe, into enqabileyo kwishishini.
