Monga njira yofunikira kwambiri yofalitsira zidziwitso zamakono, kukhwima ndi luso lakapangidwe ka zowonetsera za LED zimakhudza kwambiri kudalirika kwazinthu, mawonekedwe ake, komanso moyo wautali. Kuchokera pakusankha zinthu mpaka kutumiza komaliza, sitepe iliyonse imafuna kuwongolera mwamphamvu kuwonetsetsa kuti malondawo atha kupirira zovuta komanso{1}}zikusintha nyengo zakunja. Tsatanetsatane wa njira zazikulu zopangira zowonetsera zakunja za LED.
Kusankha ndi Kuyang'anira Zopangira Zakuthupi
Kupanga zowonetsera zakunja za LED kumayamba ndi kusankha-zida zopangira zapamwamba kwambiri. Zigawo zazikuluzikulu zikuphatikiza nyali za LED, ma driver IC, ma PCB, zida zotsekera, ndi ma module amphamvu. Monga pachimake cha gawo lowonetsera, nyali za LED ziyenera kupereka kuwala kwakukulu, kusiyana kwakukulu, ndi kukana kwanyengo. Nthawi zambiri zimakhala zopanda madzi komanso zopanda fumbi, pogwiritsa ntchito njira yapadera yopakira. Ma Driver IC amawongolera bwino kuwala ndi mtundu wa pixel, ndipo kukhazikika kwawo kumakhudza mwachindunji kuwonetsa kusasinthika. Ma PCB amafunikira kutenthetsa kwambiri komanso kuwononga dzimbiri-yosamva kutentha kuti athe kupirira zovuta monga kutentha kwambiri ndi chinyezi chambiri. Kuphatikiza apo, zinthu zonse zimayesedwa mozama kwambiri kuti zikugwirizana ndi chilengedwe zisanasungidwe, kuphatikizapo kuyezetsa -kukalamba kwambiri, chinyezi, ndi kuyesa mphamvu zamakina, kuti zitsimikizire kuti zikutsatira miyezo yamakampani.
SMT Mounting ndi Circuit Assembly
Pambuyo poyang'anira zida zopangira, njira yokhazikitsira ya SMT (surface mount technology) imayamba. Sitepe iyi imagwiritsa ntchito zida zodziwikiratu kuti zikhazikitse mwatsatanetsatane zida monga ma driver IC, ma resistors, ndi ma capacitor pa PCB, kuwateteza motetezeka kudzera munjira yosinthira. Izi zimafuna kuwongolera kutentha kwambiri kuti muteteze kuzizira kwa solder ndi kuwonongeka kwa zigawo. Pambuyo pake, ma LED amatetezedwa kumalo osankhidwa pa PCB pogwiritsa ntchito ma bonders olondola ndi mawaya, ndikumaliza kulumikiza magetsi. Kuti mawonedwe akunja atetezedwe, m'pofunika kuonetsetsa kuti chitetezo cha madzi chikatha pambuyo pa msonkhano wadera, monga kumatira ndi zokutira zofananira ({4}}zosaonongeka, zopopera mchere{{5}zosaonongeka, ndi mildew{6}}zotsimikizirani{6}}zothandizira kuti komitiyi isachite dzimbiri.
Module Encapsulation ndi Kutsekereza Madzi
Module ya LED ndiye gawo loyambira lowonetsera, lomwe lili ndi ma LED angapo, mayendedwe oyendetsa, ndi mawonekedwe oziziritsira kutentha. Panthawi yophatikizira ma module, ma module board ndi nyumba zimatetezedwa pamodzi pogwiritsa ntchito makina osindikizira olondola-, otsatiridwa ndi jekeseni wa poto wapadera (monga silikoni kapena epoxy) kuti atsimikizire kuti madzi sangatseke ndi kutseka fumbi. Potting kompositi sikuyenera kukhala ndi kuwala kwapamwamba kwambiri kuti zitsimikizire mtundu wake komanso kukhala ndi UV-yosamva chikasu kapena kusweka pakapita nthawi{4}}panja kwa nthawi yayitali. Kuphatikiza apo, m'mphepete mwa gawoli ndi mipata iyenera kusindikizidwa yachiwiri pogwiritsa ntchito zingwe zosindikizira kapena kuwotcherera akupanga kuti zitsimikizire kuti IP65 ili ndi chitetezo chokwanira, kukwaniritsa zofunikira zakunja kwakunja monga mvula yambiri ndi fumbi.
Kupanga Kapangidwe ka nduna ndi-Msonkhano Wapakanema Wathunthu
Makabati a zowonetsera zakunja za LED nthawi zambiri amakhala opangidwa ndi aluminiyamu aloyi kapena kufa-zotayira zotayira, zopatsa mphamvu zopepuka komanso zolimba kwambiri. Kupanga nduna kumafuna zida zamakina za CNC zodulira, kubowola, ndi chithandizo chapamwamba (monga anodizing kapena kupopera) kuti zithandizire kukana dzimbiri komanso kutulutsa kutentha. Nthawi yonse-yophatikiza sikirini, ma module angapo amatetezedwa mkati mwa nduna pogwiritsa ntchito ma pin ndi zokhoma. Njira zosinthira mwatsatanetsatane zimatsimikizira kusinthasintha kwa pixel kuti asawonetse ma pixel kapena mizere yowala. Makabati amalumikizidwa pogwiritsa ntchito zolumikizira zopanda madzi ndi mapulagi oyendetsa ndege kuti awonetsetse kuti ma siginecha akhazikika komanso otetezeka.
Yatsani-poyesa ndi Kuunika Ubwino
Mukamaliza{{0}sikirini yonse, chinthucho chimatenthedwa kwambiri-pakuyesedwa. Kuyeza kotentha kwambiri (50 degrees -60 degrees ) ndi kuwala kwambiri (kudzaza kwathunthu) kwa maola opitirira 72 kumatengera nthawi yayitali-kugwiritsa ntchito ndi zowonera kuti zitha kulephera msanga. Kuphatikiza apo, zida zowunikira zaukadaulo zimagwiritsidwa ntchito kuwongolera magawo azithunzi monga mawonekedwe owala, mtundu wa gamut, kutsitsimula, komanso kusiyanitsa kuwonetsetsa kuti chiwonetserochi chikukwaniritsa kapangidwe kake. Pomaliza, chinthu chomalizidwacho chimayesedwa kuti chisatseke madzi (monga ma jets othamanga kwambiri), kuyezetsa kugwedezeka kwamakina, ndi ziphaso zachitetezo chamagetsi (monga CE ndi UL) kuti zitsimikizire kudalirika kwake.
Kupaka ndi Kutumiza
Zowonetsa za LED zomwe zimapambana mayeso onse zimayikidwa mwaukadaulo. M'kati mwa bokosilo muli thovu lochititsa mantha-lomwe limayamwa, ndipo kunja kwake ndi kotsekeredwa m'mabokosi osalowa madzi ndi chinyezi-mabokosi amatabwa kapena achitsulo kuti musamavutike ndi kuphulika ndi chinyezi chamayendedwe. Buku laukadaulo, kalozera woyika, ndi zikalata zotsimikizira zimaphatikizidwanso kuti zitsimikizire kugwiritsidwa ntchito moyenera ndi kukonza.
Mwachidule, njira yopangira zowonetsera zakunja za LED imaphatikiza uinjiniya wamagetsi, sayansi yazinthu, ndiukadaulo wopanga zolondola, zomwe zimafunikira miyezo yapamwamba pagawo lililonse. Pokhapokha pokha pokha pokha pokhapo titha kupanga zowonetsera zapamwamba kwambiri-zosasunthika panja, zopatsa zithunzi zabwino kwambiri komanso moyo wautali.
