Zowonetsera za LED ndi zinthu zamagetsi.Malingana ngati ali zinthu zamagetsi, iwo mosakayikira adzalephera panthawi yogwiritsira ntchito.Ndiye ndi malangizo ati okonzera zowonetsera za LED?

Anzake omwe adalumikizana ndi zowonetsera za LED amadziwa kuti zowonetsera za LED zimaphatikizidwa pamodzi chidutswa ndi chidutswa cha ma module a LED.Monga tanenera kale, zowonetsera zowonetsera za LED ndi zinthu zamagetsi, kotero mawonekedwe ake oyambirira ndi malo owonetsera (nyali pamwamba), PCB (bodi lozungulira), ndi malo olamulira (IC chigawo chapamwamba).

Ponena za malangizo okonzekera zowonetsera za LED, tiyeni tikambirane za zolakwika zomwe zimachitika poyamba.Zolakwika zodziwika bwino ndi izi: "zowunikira zakufa", "mbozi", zotchinga zamitundu yosowa pang'ono, zowonera zakuda pang'ono, zowonera zazikulu zakuda, ma code owonongeka pang'ono, ndi zina zotero.

Ndiye mungakonze bwanji zosokoneza wamba izi?Choyamba, konzani zida zokonzera.Zigawo zisanu zamtengo wapatali kwa wokonza zowonetsera za LED: ma tweezers, mfuti yamoto yotentha, chitsulo chosungunuka, multimeter, khadi yoyesera.Zida zina zothandizira zimaphatikizapo: phala la solder (waya wa malata), kukwezera flux, waya wamkuwa, guluu, etc.

1. Vuto la "kuwala kwakufa" pang'ono

"Kuwala kwakufa" komweko kumatanthawuza kuti nyali imodzi kapena zingapo panyali yamtundu wa LED siziwala.Kusawoneka kotereku kumagawidwa kukhala kosawoneka bwino komanso kulephera kwapang'ono kwa mtundu.Nthawi zambiri, izi ndikuti nyaliyo ili ndi vuto.Mwina ndi yonyowa kapena chipangizo cha RGB chawonongeka.Njira yathu yokonzera ndiyosavuta, ingolowetsani mikanda ya nyali ya LED yokhala ndi fakitale.Zida zomwe zimagwiritsidwa ntchito ndi ma tweezers ndi mfuti zamoto.Mukasintha mikanda yotsalira ya nyali ya LED, gwiritsani ntchito Yesaninso khadi yoyeserera, ngati palibe vuto, yakonzedwa.

2. Vuto la "mbozi".

"Caterpillar" ndi fanizo chabe, lomwe limatanthawuza chodabwitsa kuti mdima wautali ndi wowala wonyezimira umapezeka pa mbali ya nyali pamene chiwonetsero cha LED chayatsidwa ndipo palibe gwero lolowera, ndipo mtunduwo umakhala wofiira.Choyambitsa chodabwitsa ichi ndi kutuluka kwa chip mkati mwa nyali, kapena kachigawo kakang'ono ka IC pamwamba pa chubu mzere kumbuyo kwa nyali, yoyamba ndiyo yambiri.Nthawi zambiri, izi zikachitika, timangofunika kugwiritsa ntchito mfuti yotentha kuti tiwuze mpweya wotentha pa "mbozi" yomwe ikutha.Ikawomba ku nyali yovuta, nthawi zambiri imakhala yabwino, chifukwa kutentha kumapangitsa kuti chipangizo chodumphira mkati chilumikizidwe.Yatsegulidwa, koma pali zoopsa zobisika.Timangofunika kupeza mkanda wa nyali wa LED womwe ukutha, ndikusintha mkanda wobisikawu molingana ndi njira yomwe tatchulayi.Ngati ndi kagawo kakang'ono ka chubu chamzere chakumbuyo kwa IC, muyenera kugwiritsa ntchito multimeter kuyeza IC pini yozungulira ndikuyisintha ndi IC yatsopano.

3. Zotsalira zamitundu zikusowa

Anzake omwe amadziwa zowonetsera za LED ayenera kuti adawona vuto lamtunduwu, ndiye kuti, malo ang'onoang'ono amitundu yosiyanasiyana amawonekera pomwe chiwonetsero cha LED chikusewera bwino, ndipo ndi lalikulu.Vutoli nthawi zambiri ndikuti mtundu wa IC kuseri kwa chipika chamtundu umawotchedwa.Njira yothetsera vutoli ndikusintha ndi IC yatsopano.

4. tsankho wakuda chophimba ndi lalikulu dera wakuda chophimba

Nthawi zambiri, chophimba chakuda chimatanthawuza kuti pamene chiwonetsero cha LED chikusewera bwino, ma modules amodzi kapena angapo a LED amasonyeza chodabwitsa kuti dera lonselo silinali lowala, ndipo dera la ma modules ochepa a LED siliwala.Timachitcha chophimba chakuda pang'ono.Timayitana madera ambiri.Ndi chophimba chachikulu chakuda.Izi zikachitika, nthawi zambiri timaganizira za mphamvu yoyamba.Nthawi zambiri, onani ngati chizindikiro cha mphamvu ya LED chikugwira ntchito bwino.Ngati chizindikiro cha mphamvu ya LED sichiwala, makamaka chifukwa chakuti magetsi amawonongeka.Ingosinthani ndi chatsopano ndi mphamvu yofananira.Muyeneranso kuyang'ana ngati chingwe chamagetsi cha module ya LED yogwirizana ndi chophimba chakuda ndichotayirira.Nthawi zambiri, kupotozanso ulusi kungathenso kuthetsa vuto lakuda.

5. garbled pang'ono

Vuto la ma code garbled am'deralo ndilovuta kwambiri.Zimatanthawuza zochitika zachisawawa, zosakhazikika, komanso zowoneka bwino zamitundu yowoneka bwino mdera lanu pomwe chiwonetsero cha LED chikusewera.Vuto lamtunduwu likachitika, nthawi zambiri timathetsa vuto la kulumikizana kwa mzere, mutha kuyang'ana ngati chingwe chathyathyathya chatenthedwa, ngati chingwe chapaintaneti chamasuka, ndi zina zotero.Pokonza, tapeza kuti waya wa aluminiyamu-magnesium ndi wosavuta kuwotcha, pomwe chingwe choyera chamkuwa chimakhala ndi moyo wautali.Ngati palibe vuto poyang'ana kugwirizana kwa siginecha yonse, ndiye kusinthanitsa gawo lamavuto la LED ndi gawo loyandikana nalo, mutha kuweruza ngati n'zotheka kuti gawo la LED lomwe likugwirizana ndi malo osokonekera awonongeka, komanso chifukwa cha kuwonongeka kumakhala makamaka mavuto a IC., Ntchito yokonza idzakhala yovuta kwambiri.Sindifotokoza mwatsatanetsatane apa.
