Momwe Mungasiyanitsire Zigawo Zosiyanasiyana za LED Zabwino ndi Zoipa?

Choyamba, ziribe kanthu mtundu umene uli wabwino ndi woipa umakhazikika. Mulingo wabwino komanso woyipa wa chigamba cha LED: Yang'anani kutsogolo kwa chigamba cha LED. Pali ngodya mu lalikulu kapena rectangle. Pali ngodya ya ngodya, ndipo mbali inayo ndi electrode yolakwika. Mitengo yabwino komanso yoyipa ya mikanda ya nyali ya LED: Yang'anani mozama kutsogolo kwa mikanda ya nyali ya LED. Pamapeto onse a mikanda ya nyali ya LED, pali ngodya yaying'ono kumapeto kwa mkanda wa nyali ya LED, ndipo mapeto a ngodyayo ndi abwino ndipo mapeto ena ndi electrode yolakwika. Nyali za chipewa cha udzu wa LED zimasiyanitsidwa ndi ma electrode abwino ndi oipa a chipewa cha udzu wa LED: LED yatsopano sinadulidwe, phazi lalitali ndilobwino, mapeto ena ndi electrode yolakwika, wopanga aliyense adzakhala wosiyana. Ngati imayikidwa ndi chigamba 2512 Kapena imodzi mwa mitunduyo ndi electrode yolakwika, pansi imasonyezedwa ndi makona atatu, mutu waukulu ndi wabwino, mutu wawung'ono ndi electrode yolakwika, ndipo phukusi lalikulu ndi labwino komanso loipa. Chachiwiri, mutha kugwiritsanso ntchito wotchi ya multimeter Ohm. Pa dial -style multimeter, sinthani kuti “Om X1 ”Pamene diode ikuwala, wotchi yofiira imagwirizanitsidwa ndi mapeto abwino a SMDLED, ndipo wotchi yakuda imagwirizanitsidwa ndi mapeto oipa a SMDLED. Chachitatu, chifukwa malire otsegulira a LED ndi pafupifupi 1.5-1.8V. N'zotheka kuti magetsi operekedwa ndi multimeter ya digito sangathe kuiyambitsa. Choncho yang'anani chizindikirocho. The patch emitting dilate (SMDLED) ili ndi mtengo woipa wokhala ndi madontho obiriwira ndipo ndi yabwino. Njira yozindikiritsa mphamvu ya LED yopulumutsa mphamvu ndi yoyipa: Njira yomwe imagwiritsidwa ntchito kwambiri ndi njira yodziwira ma multimeter. Mukamagwiritsa ntchito ma multimeter kuti muwone kuwala kotulutsa diode, muyenera kuigwiritsa ntchito “R ×L0K ”mafayilo. Kuthamanga kwa chitoliro cha diode womvetsa chisoni ndi pafupifupi 3V, ndipo wotchi yapadziko lonse ili mkati “R ×Loke ”Ndipo pamene kukana zotsatirazi kutsekedwa. Batire yomwe ili patebulo ndi 1.5V yokha. Pansi pa chitoliro kuthamanga dontho. Mosasamala kanthu za mwayi wabwino ndi wobwerera kumbuyo, diode yotulutsa kuwala sikungayatse, ndipo sikungadziwike. “R ×1 ”Pa tebulo lapamwamba, 9V (kapena 15V) mabatire othamanga kwambiri amalumikizidwa, omwe ndi apamwamba kuposa kutsika kwapansi, kotero angagwiritsidwe ntchito kuti azindikire kuwala -kutulutsa diode. Pakuyesa, mapiritsi awiriwa amalumikizidwa ndi njira ziwiri za kuwala -emitting diode. Mzati yabwino imalumikizidwa) ku mtengo wabwino;. Kenako gwirizanitsani mapiritsi awiriwa ndi ma diode owala. Panthawi imeneyi, ndi kubwerera m'mbuyo. Ngati acupuncture imatembenuzidwa kapena osasunthika, ma diode owala awonongeka kaya atembenukire kumutu kapena kumbuyo. Tsimikizirani chipewa cha udzu cha LED chabwino ndi cholakwika: mkati mwa LED, zikhomo zolumikizidwa ku bulaketi ndi maelekitirodi olakwika, ndipo zikhomo za maulalo ang'onoang'ono a bulaketi ndi chigamulo chabwino cha 5050 chigamba cha LED chabwino: lonse 5050 chigamba cha LED ndi lalikulu, mu ngodya zinayi zakumanja Pali ngodya yokhala ndi ngodya yaing'ono yosowa, yomwe ndi malo a bwalo laling'ono. Makona ena akumanja alibe ngodya yaying'ono. Mapeto a kusowa kwakung'ono kwa ngodya ndi electrode yolakwika, ndipo mapeto ena ndi mtengo wabwino. Malingaliro a kampani Zhuhai TIANHUI Optoelectronics Technology Co., Ltd. ndi chitukuko cha LED kuwala -emitting diode mndandanda wa chitukuko mankhwala, chigamba LED kupanga processing, malonda ndi utumiki-oriented mabungwe wamba. Zogulitsa zimagwiritsidwa ntchito kwambiri pozungulira makompyuta, zolumikizirana, zoseweretsa zamagetsi ndi zamagetsi, zida zapakhomo ndi zowunikira, zamagetsi zamagalimoto, zida zamankhwala ndi madera ena ambiri opanga.
