Kodi kuwala kwa mbewu ya LED ndi koyenera kwambiri kuti mbewuzo zikule?

Kutalika kwa kuwala kwa chomera cha LED ndikoyenera kwambiri pakukula kwa mbewu, maluwa ndi zipatso. Nthawi zambiri, mbewu zamkati ndi maluwa zimakulirakulirabe pakapita nthawi. Chifukwa chachikulu ndikusowa kwa magetsi. Kuwala kwa LED komwe kuli koyenera kutengera mitundu yofunikira yazomera sikungalimbikitse kukula kwawo, komanso kumawonjezera nyengo yamaluwa ndikusintha maluwa.
Kugwiritsa ntchito makina opangira magetsi ochulukirapo popanga zaulimi monga nyumba zobiriwira, malo obiriwira komanso zinthu zina mbali imodzi kumatha kuthetsa zoperewera zakusowa kwa dzuwa zomwe zimapangitsa kuti kukoma kwa tomato, nkhaka ndi masamba ena obiriwira awonongeke, ndi Komano, imathandizanso kupititsa patsogolo masamba otentha a solanum. Idzatchulidwa mozungulira Chikondwerero cha Spring kuti tikwaniritse cholinga cholima kunja kwa nyengo.
Mukamayendetsa chomera cha LED kudzera mu thumba lololeza, ma LED nthawi zambiri amapangitsa ma ripple apano ndi DC amakono a inductor kutengera ndi fyuluta yomwe yasankhidwa. Izi sizingowonjezera matalikidwe a RMS azomwe zilipo mu LED, komanso kuwonjezera mphamvu zake zamagetsi. Izi zitha kukulitsa kutentha kwa mphambano ndikukhala ndi gawo lofunikira pamoyo wa LED.
Ikakhala yotsika poyerekeza ndi kutsegulira kwa LED (gawo loyatsa magetsi loyera lili pafupifupi 3.5V), zomwe zikudutsa mu LED ndizochepa kwambiri. Pamwambapa, izi zikuwonjezeka mopitilira muyeso wamagetsi akutsogolo. Izi zimalola kuti LED ipangidwe ngati gwero lamagetsi lokhala ndi ma resistor angapo, ndi chenjezo: mtundu uwu umangogwira ntchito pakadali pano DC imodzi. Ngati DC ikupezeka mu LED ikusintha, ndiye kuti kukana kwamtunduwu kuyeneranso kusintha nthawi yomweyo kuti ziwonetse zomwe zikugwira ntchito pano. Pakadali pano kutsogolo kwakukulu, kutaya kwamphamvu mu LED kutenthetsa chipangizocho, chomwe chidzasinthe kutsika kwamagetsi kutsogolo ndi kusinthasintha kwamphamvu. Ndikofunikira kwambiri kuti muganizire mozama za kutentha kwanyengo mukamayang'ana kutaya kwa LED.
Kuwala kosinthika kumafunikira nthawi zonse kuyendetsa magetsi a chomera cha LED, ndipo pakali pano pamafunika kusungidwa mosasamala kanthu zamagetsi olowera. Izi ndizovuta kuposa kungolumikiza babu ya incandescent ndi batri kuti muyipatse.
