Mavuto Odziwika Ndi Ma Diode Owala Ndi

Kodi mwakumanapo ndi zovuta zambiri zomwe simukuzimvetsa, ndipo ndizovuta ziti zomwe zimafala kwambiri? Chifukwa chiyani ma diode otulutsa kuwala sangakhale ochulukirapo kapena opitilira muyeso amagwiritsa ntchito kuwala koyera kwa LED? Mwachidule, amafotokozedwa ndi LED yoyera ya 5mm yomwe imagwiritsidwa ntchito kwambiri. Mphamvu yake yogwira ntchito nthawi zambiri imakhala mkati mwa 3.0-3.5V, ndipo nthawi yogwira ntchito ndi 20mA 20mA. Komabe, anthu ambiri amaganiza molakwika kuti kugwiritsa ntchito nyali zoyera za LED zokhala ndi ma-voltage kapena overcurrent kudzakhala kowala, ndipo zotsatira zake zenizeni ndikuti pambuyo pa 15mA, kuwala kwa kuwala kumakula kwambiri. Pambuyo pa 20mA, palibe pafupifupi osawona. Koma pali malungo zoonekeratu. Palinso mayeso a moyo: 20mA yagwira ntchito kwa mwezi umodzi, ndipo kuchepetsedwa ndi 5% yokha. Tsopano pali 95% kuwala flux. Pamene 30mA ikugwira ntchito mpaka masiku 19, mphamvu ya kuwala ndi 50% yokha. Zitha kuganiziridwa kuti kuwala koyera kwa LED komwe kumatha kugwira ntchito maola 100,000 pansi pazikhalidwe zodziwika bwino kumagwiritsidwa ntchito pamafunde akuluakulu, ndi moyo wa maola 600 okha! Ma LED amatha kugwiritsidwa ntchito kwa maola opitilira 50,000 pofotokozera, ndipo opanga ena amati Ma LED ake amatha kugwira ntchito pafupifupi maola 100,000, koma izi sizikutsimikizira kuti zida za LED zitha kugwiritsidwa ntchito nthawi yayitali. Olakwika ntchito ndi ndondomeko mosavuta “Kuwononga ”Ma LED, ma LED amawonongeka pang'onopang'ono pakapita nthawi. Zoneneratu zina zikuwonetsa kuti ma LED apamwamba amatha kukhalabe ndi kuwala kopitilira 60% ya kuwala koyambirira pambuyo pa maola 50,000 akugwira ntchito mosalekeza. Kutalikitsa moyo wa LED, m'pofunika kuchepetsa kapena kuchotsa kwathunthu mphamvu yotentha yopangidwa ndi chipangizo cha LED. Mphamvu yotentha ndiye chifukwa chachikulu chomwe LED imasiya kugwira ntchito. Izi zimafotokozedwa kuti zigwiritse ntchito ma diode otulutsa kuwala. Kuti mumve zambiri, chonde lemberani kukaonana ndi kasitomala pa intaneti kuti mudziwe zambiri.
