Kodi tingayese bwanji kuchepetsa kuwala kwa LED?
Malinga ndi tanthauzo la moyo wa zinthu za LED mumakampani a LED, nthawi yamoyo ya LED ndi nthawi yogwira ntchito kuyambira pamtengo woyambira mpaka kuzimiririka kwa kuwala mpaka 50% ya mtengo woyambirira. Izi zikutanthauza kuti LED ikafika pa moyo wake wothandiza, kuwala kwa LED kumakhalabe koyaka. Komabe, pansi pa kuyatsa, ngati kuwala kumachepetsedwa ndi 50%, kuwala sikuloledwa. Nthawi zambiri, kuyatsa kwa kuyatsa kwamkati sikungakhale kopitilira 20%, ndipo kuyatsa kwakuya kwakunja sikungapitirire 30%.
Kuchepetsa kuwala kwa ma LED oyera ndi imodzi mwazinthu zofunika kwambiri kulowa mumsika wowunikira. Opanga nthawi zambiri amayesa kuchepetsa m'njira zitatu:
1) Njira yowonera: LED imawunikira mosalekeza, ndipo kuwala ndi kusintha kwamitundu kumawonedwa ndi maso.
2) Gwiritsani ntchito choyesera chamtundu wowala: Pa kuyatsa kosalekeza kwa LED, nthawi zambiri ikani ma LED mu tester yamtundu wowala, lembani zotsatira zoyesa, ndikuwonetsa zotsatira za mayesero kudzera mu EXCEL kapena zida zina.
3) Gwiritsani ntchito zida zoyesera zaukadaulo kuti muyeze kuchepetsedwa kwa kuwala, ndiye kuti, ikani ma LED mu zida zoyesera. Panthawi yowunikira mosalekeza, makinawo amatsata kuwala ndi kusintha kwamtundu wa LED munthawi yeniyeni ndikupanga tebulo lazidziwitso.
