Kupfuura makore ekushanda neruzivo nevagadziri vemwenje, isu tinowanzo kunzwa kuti vagadziri ve luminaire vanozeza kutenga zviri nani magetsi e LED.Kusiyana neizvi, ivo havazive kusiyanisa yakatengwa magetsi emagetsi e LED, uye ivo vari kunetsekawo nezvekuti vakabhadhara mutengo wakakwira kune yakaderera-mhando yemagetsi LED.Naizvozvo, semugadziri wemwenje, zvakaoma kupindura kutengwa kwemagetsi e LED.Nemhaka yekuti hutano hwekugadzirisa magetsi hunooma kutarisa, hwave hwakwegura kwemaawa mana mune yayo pachayo yekugadzirisa, uye vamwe vakatokura maawa 24-72.Nekudaro, ichi chigadzirwa chekare chinowanzo kutenderedza 5% kana kupfuura mukati memwedzi 3-6 yekusununguka.Kazhinji, mumamiriro ezvinhu akaipa akadaro, vanogadzira luminaire vanotambura, vanova vatengi, uye vanorasikirwa nevatengi.
Zvakadini nekufungidzira kunaka kweiyo LED magetsi ekupa?Tinogona kuzvizivisa kubva muzvikamu zvinotevera:
Chekutanga:kusundira iyo yekugadzirisa chip-IC.
Iyo yepakati yemukati yekutyaira magetsi ekufambisa ndeye yakabatanidzwa dunhu, uye zvakanakira nekuipa kweiyo yakabatanidzwa redunhu inogona kukanganisa zvakananga ese ekuchinja magetsi magetsi.Mutyairi akabatanidza masekete emafekitari makuru akaiswa mumafekitari makuru uye epakati-kati ekurongedza;mutyairi akabatanidzwa edunhu tekinoroji yemafekitori madiki ekugadzirisa ndeyekukopa nekukurumidza dhizaini yekusimudzira mafekitori makuru, uye kuwana kurongedzerwa kwemafekitori madiki uye epakati-saizi ekurongedza, ayo asingawanzo kuvimbisa kuenderana kwebatch integrated circuits.uye kuvimbika, zvichikonzera kuti simba rekutyaira rive risingashande pasina chikonzero mushure menguva yekushandiswa.Naizvozvo, iyo yakabatanidzwa yedunhu pamagetsi emagetsi e LED inoramba kukwenenzverwa, izvo zviri nyore kumugadziri wemwenje kuti abate chirongwa chedunhu chakabatanidzwa uye kuverenga mutengo wekusimudzira, kuitira kuti uve nechokwadi chemutengo unoshanda weiyo switching simba rekupa chigadzirwa.
Chepiri:Transformer.
Iyo inoshanda processor inogona kutariswa sehuropi nerve centre yemunhu anochinja magetsi, nepo inobuda simba uye yakakwirira tembiricha kuramba inotemwa neshanduko.Transformers inotora AC ikozvino - electromagnetic simba - DC simba, uye yakawandisa kinetic simba inogona kugutsa muchina.Iyo yakakosha yemukati yetransformer ndiyo musimboti uye waya package.
Hunhu hwepakati ndiyo kiyi kune transformer, asi sehari, hazvisi nyore kuziva.Iyo yakapusa chitarisiko chiziviso ndeichi: chitarisiko chakasvibira, chakakora uye chakapenya, uye reseri divi rakakwenenzverwa uye chiteshi chemagetsi chigadzirwa chakanaka.Parizvino, iyo magineti musimboti inoshandiswa neShanghai Nuoyi ndeye PC44 magineti musimboti, iyo inoshandiswa kugadzira mold, iyo inovimbisa kushanda kwepamusoro kweiyo switching magetsi.
Iwaya pasuru inogadzirwa nemhangura core wire winding.Chigadzirwa chemhando yemhangura core wire chikamu chakakosha chehupenyu hwebasa reiyo reaction transformer.Copper-clad aluminium cables ehukuru hwakafanana i1/4 mutengo wewaya dzvuku dzemhangura.Nezvikonzero zvekudhura uye kushanda nesimba, vagadziri veshanduko vanowanzo sanganisa matransformer nemhangura yakavhara aluminium waya wraps.Zvino, kana tembiricha yetransformer ichikwira, kukuvara hakushande, zvichiita kuti magetsi ekuchinja uye mwenje wese ushaye simba.Nekuda kweizvozvo, zvigadziriso zvakawanda zvemwenje, kunyanya zviya zvine magetsi ekudzoreredza, zvinowanzo chinja nekudzika mushure memwedzi mitanhatu yekusununguka.Nzira yekusiyanisa sei kana copper core wire iri red copper waya kana copper clad aluminium?Shandisa mwenje kuti uvheneke uye nekukurumidza kupisa copper clad aluminium.Iyo inogona zvakare kunyatso kuyera kukosha kwekupokana kweiyo solenoid coil.
Chetatu:electrolytic capacitors uye chip ceramic capacitors.
Isu tese tinoziva kuti isu tese tinoziva mhando uye hupenyu hwesevhisi ye electrolytic capacitors, uye isu tese tinoitora zvakanyanya.Nekudaro, isu tinowanzo kutarisisa iyo chigadzirwa mhando mirau yekutumira kunze capacitors.Muchokwadi, hupenyu hweiyo derived capacitor inokanganisa zvakanyanya kuhupenyu hwekuchinja kwemagetsi.Kushanda kwekushanda kwekushandura kwesimba pamagumo ekutungamirira-kubuda kunosvika 6,000 nguva pasekondi, zvichiita kuti kuwedzerwa kwekupona kwekudzivirira kwe capacitor uye kugadzirwa kwemakemikari akaita setsvina.Pakupedzisira, lithium bhatiri electrolyte inopisa uye inoputika.Inokurudzirwa zvakanyanya kutumira kunze electrolytic capacitors: sarudza yakakosha electrolytic nzira ye LED, uye iyo general modhi yakatarwa inotangira kubva kuL. Panguva ino, yedu yekuburitsa electrolytic nzira dzese dzese electrolytic capacitor ine high service hupenyu hweAihua.
Ceramic capacitors: Zvishandiso zvakakamurwa kuita X7R, X5R uye Y5V, uye iyo chaiyo capacitance yeY5V inogona kungosvika 1/10 yeiyo yakakosha kukosha, uye iyo yakajairwa capacitance kukosha inongoreva ku0 volts panguva yekushanda.Naizvozvo, uku kushomeka kudiki uye kusarudzwa kwakashata kunotungamira kune musiyano wemitengo, ichideredza zvakanyanya hupenyu hwesevhisi yekuchinja magetsi.
Chechina:circuit musimboti uye welding nzira yekuchinja magetsi ekupa zvigadzirwa.
Kusiyanisa kunaka kwechirongwa chekugadzira: Pamusoro peiyo tekinoroji yehunyanzvi maonero, inogona zvakare kusiyaniswa zvinoenderana nedzimwe nzira dzekuona, senge inonzwisisika marongerwo ezvikamu, kuchena, kurongeka kwemhepo, kupenya kwewelding, uye kureba kwakajeka.Technician yakanaka haidi kuita zvinokanganisa dhizaini.Kune wiring, handcrafting uye zvikamu zvakare kuratidzwa kukuru kwekushayikwa kwakanyanya kwesimba rehunyanzvi.
Welding nzira: manual welding uye peak welding process.Sezvatinoziva tese, iyo peak welding process mhando yemechanicha otomatiki inofanira kunge iri nani kune manual welding.Chiziviso nzira: kunyangwe paine tsvuku glue kumashure (yekubatsira solder paste process process + yemagetsi welding fixture inogonawo kupedzisa peak welding, asi mutengo wekugadzirisa wakakwira zvakanyanya).
SMD spot welding yekuongorora chiridzwa: AOI.Mune SMD chinongedzo, nzvimbo yacho inogona kutarisa mamiriro e desoldering, nhema soldering, uye zvikamu zvisipo.
Panguva ino, chigadziriso chemwenje chinopenya mushure menguva yekushandiswa, iyo inonyanya kukonzerwa ne-de-soldering yemagetsi ekuchinja kana mwenje we LED.Kuongorora kwekuparara kwechigadzirwa ichi hakusi nyore kupfuudza kuongororwa kwekuchembera, saka zvakakosha kushandisa AOI kutarisa chigamba chemhando yemagetsi ekuchinja.
Cheshanu:Tarisa kuchembera racks uye tembiricha yekuchembera makamuri muhuwandu hukuru hwekuchinja zvigadzirwa zvemagetsi.
Hazvina mhosva kuti zvakanaka sei zvigadzirwa uye kugadzirwa kuri muzvigadzirwa zvemagetsi uye zvigadzirwa zvemagetsi, kana kuchembera kunofanirwa kuongororwa.Zvakaoma kutarisa mishumo yekuongorora inouya yezvikamu zvemagetsi uye magetsi emagetsi.Chete zvinoenderana nekuchembera kwesimba rekuchinja uye tembiricha yekuyera yekuongorora yekamuri inoenderera yekupisa tembiricha, inogona kuvimbika kwemhando yemagetsi ekuchinja uye kana zvigadzirwa zvine njodzi dzekuchengetedza zvinogona kuongororwa.
Mhedzisiro yenhamba yakawanda yekuenderera mberi kweyepamusoro-tembiricha sampling inspections: Kusashanda kwekuchinja magetsi panguva ino kuri pakati pechiuru chimwe chete kubva muzana, uye kusashanda uku kunozowanikwa chete kana zviuru zvekuramba zvichichembera.
Imba inoenderera yekupisa tembiricha inogona kutevedzera hutsinye hwechisikigo nharaunda umo magetsi ekuchinja anoshanda.Kuongororwa kwesampling pasi pezviyero zvakaomesesa kunogona kuratidza huwandu hukuru hwematambudziko akadai seasiri esainzi dhizaini zvigadziriso, urombo mbishi, zvigadziriso zvemwenje zvisingashande, uye kukanganisa kweakakwira-voltage circuit breaker.
Kuchembera kwenguva refu patembiricha yekamuri: sarudza kutadza kurongeka senge desoldering, kudonha kwezvikamu, kukanganisa, nezvimwewo, kusefa kusashanda kwekutanga kwezvikamu, uye kudzikisira zvine hungwaru kutadza kwechigadzirwa chakapedzwa (1% kusvika 1/1000) .
Pakupisa kwekamuri, kuchembera kunodya michina yekuchembera yakawanda, midziyo nevashandi.Zuva rega rega, 100,000 zvigadziriso zvidyarwa zvinochinja magetsi nekudzima.Michina yekuchembera nemidziyo inovhara nzvimbo inosvika mazana mashanu emamita mativi, ine anopfuura zviuru gumi zvinzvimbo zvekuchembera, uye kuchembera kwemutsara wekugadzira kwapera, izvo zvisingawanzo muindasitiri.
