Kodi mungakonze bwanji zolakwika zazing'ono izi?
Choyamba, konzani zipangizo zokonzera.Zinthu zisanu zofunika kwaChiwonetsero cha LEDogwira ntchito yokonza ndi tweezers, hot air gun, soldering iron, multimeter, ndi test card.Zida zina zothandizira ndi monga solder phala (waya), soldering flux, waya wamkuwa, guluu, etc.
1, Nkhani ya mbozi
"Caterpillar" ndi liwu lophiphiritsira, kutanthauza chodabwitsa chamzere wautali wakuda komanso wowala wowonekera pazithunzi zina za LED pansi pamagetsi opanda gwero lolowera, makamaka lofiira.Chomwe chimayambitsa izi ndi kutayikira kwa chip chamkati cha nyali, kapena kagawo kakang'ono ka IC kuseri kwake, pomwe woyamba amakhala ambiri.Nthawi zambiri, izi zikachitika, timangofunika kugwira mfuti yotentha ndikuwomba mpweya wotentha pamodzi ndi "mbozi" yomwe ikutulutsa magetsi.Tikamawuzira ku kuwala kovutirapo, nthawi zambiri zimakhala bwino chifukwa kulumikizana kwa chip kwamkati kumasweka chifukwa cha kutentha, komabe pali ngozi yobisika.Timangofunika kupeza mkanda wa LED womwe ukutuluka ndikuusintha molingana ndi njira yomwe tafotokozayi.Ngati pali dera lalifupi lozungulira kumbuyo kwa IC, ndikofunikira kugwiritsa ntchito multimeter kuyeza dera loyenera la pini la IC ndikusintha ndi IC yatsopano.
2, Vuto la "kuwala kwakufa" kwanuko
"Kuwala kwakufa" kumatanthawuza nyali imodzi kapena zingapo paChiwonetsero cha LEDzomwe sizikuunika.Mtundu woterewu wa non light up umasiyanitsidwa ngati osawunikira nthawi zonse komanso mtundu wamtundu wopanda kuwala.Nthawi zambiri, izi zimachitika chifukwa cha vuto la kuwala komweko, mwina kukhala konyowa kapena chip cha RGB chikuwonongeka.Njira yathu yokonzera ndiyosavuta, yomwe ndikusintha ndi fakitale yoperekedwa ndi zida zopangira zida za LED.Zida zomwe zimagwiritsidwa ntchito ndi ma tweezers ndi mfuti zamoto.Mukasintha mikanda ya LED yotsalira, Yesaninso ndi khadi yoyesera, ndipo ngati palibe zovuta, yakhazikitsidwa kale.
3, Local mtundu chipika chosowa vuto
Anzanu omwe amadziwa zowonetsera zowonetsera za LED awonadi vuto lamtunduwu, lomwe ndi lakuti pamene chiwonetsero cha LED chikusewera bwino, pali chipika chaching'ono chokhala ndi mawonekedwe amtundu.Vutoli nthawi zambiri limayamba chifukwa cha kuyaka kwa mtundu wa IC kumbuyo kwa chipika chowongolera.Njira yothetsera vutoli ndikusintha ndi IC yatsopano.
4, Vuto la code garbled Local
Vuto la zilembo zam'deralo ndizovuta kwambiri, kutengera zomwe zimachitika mwachisawawa zamitundu yosiyanasiyana m'malo ena azithunzi zowonetsera za LED panthawi yosewera.Vutoli likachitika, nthawi zambiri timafufuza kaye vuto lolumikizana ndi chingwe cholumikizira.Titha kuyang'ana ngati chingwe cha riboni chatenthedwa, ngati chingwe cha netiweki chamasuka, ndi zina zotero.Pokonza, tidapeza kuti waya wa aluminiyamu wa magnesium umakonda kuyaka, pomwe waya weniweni wamkuwa amakhala ndi moyo wautali.Ngati kulumikizidwa konse kwa siginecha kumayang'aniridwa ndipo palibe zovuta, ndiye kuti kusinthanitsa gawo lolakwika la LED ndi gawo loyandikana nalo lomwe likusewera kutha kudziwa ngati ndizotheka kuti gawo la LED lomwe likugwirizana ndi malo osasewera bwino liwonongeke.Zomwe zimayambitsa zowonongeka nthawi zambiri zimakhala zovuta za IC, ndipo kukonza ndi kusamalira kungakhale kovuta kwambiri.Sitifotokoza zambiri za momwe zinthu zilili pano.
5, Chinsalu chakuda chakuda kapena vuto lalikulu lakuda
Nthawi zambiri pamakhala zifukwa zingapo zomwe zingayambitse izi.Tiyenera kufufuza ndi kuthetsa vutolo pogwiritsa ntchito njira zoyenera ndi masitepe.Nthawi zambiri, pamakhala mfundo zinayi zomwe zingayambitse zowonera zakuda pazenera lomwelo la LED, zomwe zitha kufufuzidwa chimodzi ndi chimodzi:
1, Kuzungulira kotayirira
(1) Choyamba, yang'anani ndikutsimikizira ngati chingwe cha serial chomwe chimagwiritsidwa ntchito kulumikiza chowongolera ndi chotayirira, chosazolowereka, kapena cholumikizidwa.Zikasanduka zakuda kumayambiriro kwa kutsitsa, zitha kukhala chifukwa cha mzere wolumikizana wotayirira womwe umasokoneza njira yolumikizirana, zomwe zimapangitsa kuti chinsalu chikhale chakuda.Osaganiza molakwika kuti chophimba sichinasunthe, ndipo mzerewo sungakhale womasuka.Chonde yang'anani nokha kaye, zomwe ndizofunikira kuthetsa vutoli mwachangu
(2) Yang'anani ndikutsimikizira ngati bolodi yogawa ya HUB yolumikizidwa ndi chinsalu cha LED ndipo khadi yowongolera ili yolumikizidwa mwamphamvu ndikuyika mozondoka.
2, Nkhani yamagetsi
Chonde onetsetsani kuti zida zonse, kuphatikiza zowongolera, zimayatsidwa moyenera.Kodi magetsi akuthwanima kapena pali vuto lamagetsi?Ndikoyenera kudziwa kuti kugwiritsa ntchito magetsi otsika kwambiri nthawi zambiri kumakonda kuchitika izi
3, Connection nkhani ndi LED unit board
(1) Ma board angapo otsatizana samawalitsa molunjika.Onani ngati magetsi a gawoli ndi abwinobwino
(2) Ma board angapo otsatizana samawalitsa mopingasa.Yang'anani ngati kugwirizana kwa chingwe pakati pa bolodi ya unit yachibadwa ndi bolodi yosadziwika bwino ikugwirizanitsidwa;Kapena chip 245 chikugwira ntchito bwino
4, Zokonda pa mapulogalamu kapena nkhani za chubu la nyali
Ngati pali malire omveka bwino pakati pa awiriwo, kuthekera kwa mapulogalamu kapena zoikidwiratu zomwe zimayambitsa ndizokwera;Ngati pali kusintha kofanana pakati pa ziwirizi, zikhoza kukhala vuto ndi chubu la nyali.
