Kugwira ntchito kwa nthawi yayitaliLEDzingayambitse kukalamba, makamaka kwamphamvu kwambiriLED, vuto la kuwola kwa kuwala ndi lalikulu kwambiri.Poyesa moyo wa LED, sikokwanira kutenga kuwonongeka kwa kuwala ngati mapeto a moyo wowonetsera LED.Ndizomveka kufotokozera moyo wotsogozedwa ndi kuchuluka kwa kuwala kwa LED, monga 5% kapena 10%.

Kuwola kowala: polipira pamwamba pa ng'oma ya photosensitive, ndi kudzikundikira kwa mtengo pamwamba pa ng'oma ya photosensitive, kuthekera kumawonjezeka, ndipo pamapeto pake kumafika pa "machulukidwe" omwe amatha, omwe ali apamwamba kwambiri.Kuthekera kwapamwamba kudzachepa pakapita nthawi.Nthawi zambiri, kuthekera kogwira ntchito kumakhala kotsika kuposa izi.Njira yomwe kuthekera kwachilengedwe kumachepa pakapita nthawi kumatchedwa "kuwola kwamdima".Pamene ng'oma ya photosensitive ikuyang'aniridwa ndikuwonekera, kuthekera kwa malo amdima (pamwamba pa photoconductor yomwe sikuwunikiridwa ndi kuwala) idakali mkati mwa mdima wakuda;M'dera lowala (pamalo a photoconductor amawunikiridwa ndi kuwala), kachulukidwe kake kachulukidwe kamtundu wa photoconductive kumawonjezeka mwachangu, ma conductivity amachulukirachulukira, ndipo voteji ya photoconductive imapangidwa, chiwongolerocho chimatha mwachangu, komanso kuthekera kwapa Photoconductor. amachepetsa mofulumira.Zimatchedwa "kuwala kutsika" ndipo kumachepetsa kumapeto.
