Tonsefe timakumana ndi zimenezi pamoyo wathu. Zangogulidwa kumeneMagetsi a LEDnthawi zonse zimakhala zowala kwambiri, koma pakapita nthawi, magetsi ambiri amakhala akuda komanso akuda. Chifukwa chiyani magetsi a LED ali ndi njira yotere?

Tiyeni tikutengereni pansi lero! Kuti timvetsetse chifukwa chomwe magetsi a LED akunyumba kwanu akucheperachepera, tifunika kumvetsetsa mawu aukadaulo - kuwola kwa kuwala kwa LED.

Magetsi a LED akagwiritsidwa ntchito kwambiri, amakhala akuda kwambiri chifukwa magetsi a LED amakhala ndi kuwonongeka kwa kuwala.

Kuchepetsa kuwala kwaNyali ya LEDmankhwala ndi chizindikiro kufooka kwa kuwala kufala. Pakali pano, kuwala attenuation digiriZida za LEDzopangidwa ndi opanga zazikulu za LED padziko lapansi ndizosiyana. Kuwongolera kwamphamvu kumakhalanso ndi kuchepetsedwa kwa kuwala, komwe kumakhudzana mwachindunji ndi kutentha, makamaka kutsimikiziridwa ndi chip, phosphor ndi ukadaulo wazonyamula. Pakalipano, kuwonongeka kwa kuwala kwa LED yoyera pamsika ndi imodzi mwazovuta kwambiri pakukula kwa kuyatsa kwa anthu.

Kuwola kowala nthawi zambiri kumatanthauza kusinthasintha kwake kowala. Poyendetsa pamwamba pa ng'oma ya photosensitive, ndi kudzikundikira kwa mtengo pamwamba pa ng'oma ya photosensitive, kuthekera kumawonjezeka mosalekeza, ndipo potsirizira pake kufika pa "machulukitsidwe" kuthekera, komwe kuli kopambana 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 amakula mwachangu, kuwongolera kumawonjezeka mwachangu, ndipo voteji ya photoconductive imapangidwa, chiwongolerocho chimatha mwachangu, komanso kuthekera kwapa Photoconductor. amachepetsa mofulumira. Kumatchedwa “kuwola kowala”.
