Kuwala kwa mizere ya LED kukuchulukirachulukira m'malo osiyanasiyana. Anthu ambiri amasangalala ndi maonekedwe amakono ndikumverera kuti amalenga, komanso kuti ndizosavuta kuziyika. Nkhaniyi ifotokoza mwatsatanetsatane momwe mungayankhire mitundu yosiyanasiyana ya zingwe za LED, kuphatikiza mtundu umodzi, zoyera zowoneka bwino, RGB, RGBW, RGBCCT, ndi mizere ya LED yoyankhulidwa.
Kuti timvetsetse bwino mawaya, tiyenera kuphunzira za kutsika kwa magetsi ndi kulumikizana kofananira kaye.
Kuponya kwamagetsi
Kutsika kwa magetsi a LED kumatanthauza kuti PCB ndi mawaya amakoka magetsi, zomwe zimapangitsa kuti gawo la mzere wa LED pafupi ndi magetsi likhale lowala kuposa mapeto. Kusagwirizana kwa kuwala komwe kumachitika chifukwa cha kutsika kwamagetsi ndi chinthu chomwe tiyenera kupewa.
Titha kupewa vuto la kutsika kwamagetsi polumikiza mizere ingapo ya LED kumagetsi amagetsi mofananira m'malo mophatikizana.
Kapenanso, titha kugwiritsa ntchito ultra-atali nthawi zonse zamakono mizere ya LED.
Kuti mudziwe zambiri za kutsika kwa magetsi, chonde werengani Kodi kutsika kwa voliyumu ya LED ndi chiyani?
Kulumikizana kofananira
Njira yodziwika bwino yopewera zovuta zotsitsa magetsi ndikulumikiza mizere ingapo ya LED molumikizana ndi magetsi, chowongolera, kapena amplifier.
Njira ina ndikulumikiza malekezero onse a mzere wa LED ku gwero lamagetsi lomwelo, chowongolera, kapena chokulitsa.
Onetsetsani OSATI kulumikiza mizere ingapo motsatizana ndi magetsi, chowongolera, kapena amplifier.
PWM amplifier
Zowongolera zonse za LED zotulutsa a PWM chizindikiro. Ngati wowongolera wa LED satulutsa mphamvu zokwanira, amplifier ya PWM imatha kukulitsa mphamvu ya PWM, motero amalola wowongolera wa LED kuyendetsa mizere yokwanira ya LED.
Momwe mungayikitsire nyali zamtundu umodzi wa LED
Mtundu umodzi kapena kuwala kwa mono LED ndikosavuta. Ili ndi mawaya awiri okha ndipo imatha kutulutsa kuwala kwamtundu winawake.
Magetsi amtundu umodzi wamtundu wa LED wokhala ndi madalaivala osatha kuzimitsa a LED
Chodziwika kwambiri ndi mzere wamtundu umodzi wa LED wolumikizidwa ndi gwero lamagetsi losazimitsidwa popanda wowongolera.
Chonde dziwani kuti mphamvu ya magetsi onse amtundu wa LED sayenera kupitirira 80% ya mphamvu yamagetsi, yomwe ndi mfundo ya 80% ya mphamvu zamagetsi.
Kuwala kwamtundu umodzi wamtundu wa LED wokhala ndi madalaivala ocheperako a LED
Nthawi zina, timafunika kusintha kuwala kwa chingwe cha LED. Chifukwa chake tiyenera kulumikiza mzere wamtundu umodzi wa LED ndi magetsi ocheperako.
Njira zodziwika bwino za dimming ndi 0-10V, Triac, ndi DALI.
