Pambuyo pazaka zachitukuko, malo odziwika omwe adachokera adapanga unyolo wokhazikika, kuyendetsa kutchuka kwa kuwonetsa kwa LED. Komabe, ilinso ndi zovuta za kutentha kwapatseko komanso kugwiritsa ntchito mphamvu kwambiri. Pambuyo pa kutuluka kwa kachikathunzi kwa chitoto wamba kuwonetsera mphamvu zamagetsi, zakopa chidwi pamsika wa LED. Njira yoyendetsa yamagetsi iyi imatha kukwaniritsa mphamvu zambiri za 75%. Ndiye kodi catchiode wamba yatsogozedwa ndi magetsi oyendetsa bwino ndi ati? Kodi Ubwino ndi wotani paukadaulo uwu?
1. Kodi Katombo wamba ndi chiyani?
"Chitoto wamba" chimanena za njira yodziwika bwino yamphamvu, yomwe ndiukadaulo wopulumutsa mphamvu wa Entercy kuti awonetse zojambula za LED. Zikutanthauza kugwiritsa ntchito njira yodziwika bwino yopangira mawonekedwe a LED, ndiye kuti r, g (ofiira, g, b, obiriwira, obiriwira, abuluu) ndi osiyana. Mwanjira imeneyi, choyamba kumadutsa mu mikanda ya iclode kenako kupita ku electrode yosasangalatsa ya IC, dontho lamphamvu la magetsi lidzachepetsedwa, ndipo kuphatikizira kwamkati kudzakhala kocheperako.
2. Kodi pali kusiyana kotani pakati pa chitoto wamba komanso malo wamba a malo odziwika?
①. Njira Zosiyanasiyana zamagetsi:
Njira yodziwika bwino ya chitoto ndikuti yoyamba yomwe imangodutsa munyengo ya iC iC, kenako ku malo oyipa a IC, yomwe imachepetsa dontho la magetsi oyambira ndi kukana kwamkati.
Ndondomeko wamba ndikuti zomwe zimachitika kuchokera ku PCB bolodi ya PCB kupita ku Right, b (lofiira, lamtambo)
②. Magetsi osiyanasiyana:
Kachisi wamba, idzapereka ndalama zapano ndi magetsi kuti r, g, b (ofiira, obiriwira, abuluu) payokha. Zofunikira za magetsi zofiira, zobiriwira komanso zamtambo ndizosiyana. Mphamvu yamagetsi yofiira ya zingwe zofiira zili pafupi 2,8v, ndi mafuta osungira magetsi obiriwira abuluu ndi pafupifupi 3.8v. Mphamvu zoterezi zimatha kukwaniritsa mphamvu zolondola komanso kugwiritsa ntchito mphamvu yocheperako, ndipo kutentha komwe kumapangidwa ndi kutsogozedwa nthawi yantchito kumakhala kotsika kwambiri.
Malo wamba, mbali inayo, imapereka R, g (ofiira, obiriwira, abuluu) voliyumu yayikulu kuposa magetsi ogwirizana. Pakadali pano, mphamvu yamagetsi yomwe imapezeka ndi ofiira, obiriwira ndi amtambo ndi ogwirizana, koma magetsi oyenera ogwiritsira ntchito magetsi atatuwo ndi otsika kwambiri kuposa 5V. Malinga ndi mphamvu ya mphamvu p = UI, pomwe sizingasinthidwe, mphamvu yayikulu, mphamvu yayikulu, ndiye kuti, yayikuluyo imamwa. Nthawi yomweyo, mtsogorowo adzatulutsanso kutentha kwambiri pantchito.
AChophimba cha padziko lonse lapansi chakumaso, Amatengera chitoto wamba. Poyerekeza ndi ma diodi yofiira, yobiriwira, komanso yopanda buluu, yomwe ili pansi pa chip ndi 3.2V, pomwe mapiri obiriwira ndi abuluu ndi madontho abwino opulumutsa mphamvu komanso ochepetsa.
3. Chifukwa chiyani chitoto chodziwika bwino cha LED chimapanga kutentha pang'ono?
Njira yapadera yodziwika bwino ya chivindikiro cha chofunda zimapangitsa kuti chiwonetsero cha LED chimangotulutsa kutentha komanso kutentha kwa kutentha. Pakakhala zochitika wamba, mu zoyera zoyera komanso posewera mavidiyo, chophimba cha chiwongola dzanja chimakhala pafupifupi 20 ℃ chotsika kuposa momwe chimapangidwira panja. Zopangidwa ndi zomwezi komanso kuwunika komweko, kutentha kwa chitoto cha chitoto cha chitoto ndi choposa 20 madigiri omwe adtsogoredwe kopitilira 50% kuposa zomwe zidachitika.
Kutentha kwambiri komanso kugwiritsa ntchito mphamvu mwa mphamvu zakhala zinthu zofunika nthawi zonse zomwe zimakhudza moyo wa kutsogozedwa ndi moyo wa kutsogoleredwa, ndi "catodi civinal Adviceve" itha kuthetsa mavuto awiriwa bwino.
4. Kodi maubwino ndi otani a catorode wamba omwe amatsogolera?
①. Magetsi olondola amasunga mphamvu kwambiri:
Chitato wamba chimatengera ukadaulo wowongolera wolamulira, kutengera mitundu yosiyanasiyana yamitundu itatu yofiyira, yobiriwira komanso yaukadaulo, ndipo imakhala ndi mphamvu yopanga 40% yotsika mtengo!
②. Kusunga kwamphamvu kwamphamvu kumabweretsa mitundu yoona:
Chikatoda wamba choyendetsa choyendetsa chimatha kuwongolera bwino mphamvu, zomwe zimachepetsa kugwiritsa ntchito mphamvu ndi kutentha. Chiwopsezo cha LED sichimayenda pansi mosalekeza opaleshoni, ndipo mtundu weniweni umawonekera bwino!
③. Kupulumutsa koona kumabweretsa moyo wautali:
Kugwiritsa ntchito mphamvu kumachepetsedwa, pongochulukitsa kwambiri kutentha kwa kachitidweko, moyenera kumachepetsa kuthekera kwa kuwonongeka kwa Add, ndikusintha kwa dongosolo lonse la chiwonetsero cha dongosolo lonse, ndipo ndikukweza dongosolo la Dongosolo lonse.
5. Kodi chitukuko chimakonda bwanji ukadaulo wamba wa cast?
Zinthu zothandizirana ndi katombo wa LED yowonetsera, monga kutsogoleredwa, kuperekera magetsi, ma driver icin, etc. Kuphatikiza apo, mndandanda wa chitoto wamba sunamalize, ndipo voliyumu yonse si yayikulu, pomwe mawonekedwe wamba amakhala 80% yamsika.
Chifukwa chachikulu chopita pang'onopang'ono ukadaulo wa Catode wamba ndi mtengo wapamwamba kwambiri. Kutengera ndi chitoliro choyambirira cholumikizira, chitoto wamba chimafuna mgwirizano wamasewera kumapeto kwa tchipisi monga tchipisi, PCB, ndi zina zambiri.
M'nthawi imeneyi yamtengo wapatali yofuna kupulumutsa mphamvu, kutuluka kwa chitoto chodziwika bwino ku Lowen Custen Shown Shown. Komabe, pali nthawi yayitali kuti mukwaniritse kukwezedwa ndi kugwiritsidwa ntchito mokwanira, zomwe zimafuna zoyesayesa zolumikizirana bwino. Monga momwe zimakhalira ndi chitukuko chopulumutsa mphamvu, chitoto chodziwika bwino chimaphatikizapo kugwiritsa ntchito ndikugwiritsa ntchito magetsi. Chifukwa chake, kupulumutsa mphamvu kumakhudzana ndi zokonda zawonetsero zowonetsera ndi kugwiritsa ntchito mphamvu zadziko.
Kuchokera momwe zinthu ziliri, Catoode wamba imayambitsa chiwonetsero chonyamula mphamvu sichingakulitse mtengo wokwera kwambiri poyerekeza ndi chithunzi wamba, ndipo isunga ndalama zomwe zimagwiritsidwa ntchito pambuyo pake, zomwe zimalemekezedwa kwambiri ndi msika.
