LED ic Chip

Intambwe mu isi yaLED yerekana, aho buri pigiseli ibaho mubuzima binyuze mumashanyarazi ya LED IC. Tekereza umurongo wo gusikana abashoferi hamwe nabashoferi binkingi bakorana nta nkomyi kugirango bakore amashusho atangaje ashimisha abumva hafi na kure.

Kuva kuri byinshiibyapa byo hanzekumaduka akurura amaso yerekanwe hamwe na ecran nziza murugo, chip ya LED umushoferi IC ni intwari zitavuzwe inyuma. Nizo mbaraga zitwara zituma buri pigiseli imurika cyane, yaba ibara rimwe, amabara abiri, cyangwa ibara ryuzuye.

Ariko mubyukuri ibyo chip ikora iki?

Chip ya LED IC ni iki?

Mwisi yisi yuzuye ibaraLED yerekana, uruhare rwa LED IC chip iroroshye ariko ni ngombwa: kwakira amakuru, gutanga ibimenyetso bya PWM neza, no kugenzura imigendekere yubu kugirango imurikire buri LED neza. Nibintu bihuza ikoranabuhanga, ritegura uburinganire bwiza bwurumuri no kugarura ibiciro kugirango bizane amashusho mubuzima.

Noneho hariho IC za periferique-intwari zitavuzwe zongeramo ubujyakuzimu nubunini mubyerekanwe. Kuva muri logique IC kugeza kuri MOS yahinduwe, nibintu byibanga bizamura uburambe bugaragara kurwego rushya.

Ntabwo chip ya LED IC yose yaremewe kimwe. Bimwe byashizweho kugirango bikoreshwe muri rusange, mugihe ibindi byateguwe neza kubikorwa byihariye. Ni ahantu nyaburanga bidashoboka, aho guhanga no guhanga bihuza gukora ibyerekanwa bikurura kandi bitangaje.

Noneho, injira mwisi ya chip idasanzwe-igenamigambi ryashizweho rifungura ubushobozi bwuzuye bwa LED yerekana. Dore akajagari: Ikoranabuhanga rya LED rikora muburyo bwihariye. Bitandukanye nibikoresho gakondo, LED yishingikiriza kumurongo uhoraho, ntabwo ihinduka rya voltage.

Aha niho imashini zidasanzwe zimurika. Intego yabo? Gutanga isoko ihoraho. Kuki ibyo ari ngombwa? Umuyoboro uhamye bisobanura gushikamaLED, hamwe na LED ihamye bisobanura amashusho atagira inenge ashimishije kandi ashimishije.

Iyi chip ya LED IC iri kure yubusanzwe. Bamwe baza bafite ibintu byongeweho byerekeranye ninganda zihariye, nka LED ikosa ryerekana, kugenzura ibyagezweho, ndetse no gukosora ubu, wongeyeho urwego rwukuri.

Amateka ya LED IC Chip

Fata urugendo usubire muri dinamike ya 1990, mugihe LED yerekana ecran yari itangiye kwiyongera. Muri kiriya gihe, byose byari byerekanwe kimwe kandi gifite amabara abiri yerekanwe, hamwe na disiki ihoraho ya voltage ya IC ku buyobozi.

Hanyuma, mu 1997, ihinduka rikomeye ryabaye igihe Ubushinwa bwatangizaga 9701-bushya budasanzwe bwo kugenzura no kugenzura chipLED yerekanaMugaragaza. Hamwe no gusimbuka bidasanzwe kuva kumurongo 16 wijimye kugera kuri 8192 itangaje, iyi chip yahinduye amashusho yerekana neza, ihindura "ibyo ubona nibyo ubona" ​​mubyukuri bifatika.

Nka tekinoroji ya LED yateye imbere, niko abashoferi bayikoresheje. Imiyoboro ihoraho yahindutse byihuse ibara ryuzuye LED yerekana, ihuza neza nibintu byihariye biranga LED. Hamwe no kwiyongera kwinshi, kwishyira hamwe kwarushijeho kwiyongera, hamwe na 16-imiyoboro ya disiki yahise iruta iyindi 8 yababanjirije.

Ihute imbere uyumunsi, aho udushya dukomeje kurenga imipaka. Kugirango ukemure ibibazo byinsinga za PCB muri pigiseli ntoya ya LED yerekana, abashoferi ba IC basunika imipaka hamwe na 48-imiyoboro ihuriweho na LED ihoraho ya chip. Nibigaragaza isi igenda itera imbere yikoranabuhanga rya LED, aho imbogamizi yonyine ari ibitekerezo byacu.

LED IC Ibipimo byerekana imikorere

Reka twibire mumutima wa LED yerekana ecran, aho ibipimo byingenzi byerekana imikorere nkigipimo cyo kugarura ubuyanja, ibara ryinshi, hamwe no kwerekana amashusho bifata umwanya wambere. Tekereza ibi: guhuza guhuza ibintu bihoraho bihoraho, itumanaho ryihuse, hamwe nihuta ryihuta ryibisubizo - byose bikorana kugirango dukore amashusho atangaje ashimisha abareba.

Mu bihe byashize, kugera ku bwumvikane buke hagati yikigereranyo cyo kugarura ubuyanja, ibara ryinshi, nigipimo cyo gukoresha byari intego itoroshye. Hagomba kubaho ubwumvikane - haba igipimo cyo kugarura ibintu cyaragabanutse, bituma imirongo yumukara itagaragara neza mumashusho yihuta ya kamera, cyangwa ibara ryinshi ryarababaje, biganisha kumurabyo wamabara adahuye.

Injira imyaka yiterambere ryikoranabuhanga. Ndashimira udushya twakozwe nabashoferi IC bakora, rimwe-bidashoboka byabaye impamo. Igipimo cyinshi cyo kugarura ubuyanja, ibara ritagira inenge, hamwe nuburanga bwamabara meza ubu bibana neza, bigatanga inzira yo kwerekana ibyasize abumva ubwoba.

Kuri LED yuzuye-amabara yerekana, ihumure ryabakoresha nibyingenzi. Niyo mpamvu kugera ku buringanire bworoshye bwumucyo muke hamwe nicyatsi kinini cyabaye ikizamini cyanyuma cyo gutwara imikorere ya IC. Nubuhamya bwo kudacogora gushakisha indashyikirwa mu isi igenda itera imbere yikoranabuhanga rya LED.

Inyungu zo Gukoresha LED IC Chip

Iyo ukoresheje chip ya LED IC, hari ibyiza byinshi ushobora kwishimira kandi ukabyungukiramo. Hano hari bimwe bikwiye kwitonderwa:

Imbaraga zo kuzigama ingufu

Reka tumurikire uburyo bwo gukoresha ingufu muri LED yerekanwe - urugendo aho guhanga udushya bihura nigihe kirekire, kandi buri watt ibara.

Mwisi yingufu zicyatsi, kuzigama imbaraga ntabwo ari intego gusa; ni inzira y'ubuzima. Iyo bigeze kuri LED yerekana, imikorere yo gutwara IC biterwa nubushobozi bwabo bwo kugabanya gukoresha ingufu badatanze umusaruro.

Nigute babigeraho? Byose bijyanye no guhangana ningufu zo kuzigama uhereye kumpande ebyiri zingenzi:

Ubwa mbere, icyibandwaho ni ukugabanya guhora kwa point point ya voltage ihindagurika. Mugabanye amashanyarazi gakondo 5V kugeza munsi ya 3.8V, gutwara IC bitanga inzira yo gukoresha ingufu neza.

Ababikora barimo gutera indi ntera hamwe na algorithm ya gihanga kandi igezweho. Ndetse bamwe bashizeho imashini zihoraho za disiki zifite ingufu zidasanzwe zingana na 0.2V gusa - kuzamura igipimo cyo gukoresha LED hejuru ya 15% no kugabanya ingufu z'amashanyarazi ku gipimo cya 16%.

Ariko dore impinduramatwara: kuzigama ingufu ntabwo ari ugukata inguni gusa - ni ukuri. Mugutanga ingufu zitandukanye kumasaro yumutuku, icyatsi, nubururu, gutwara IC byemeza ko voltage numuyoboro bigabanywa neza. Igisubizo? Kugabanya gukoresha ingufu, kugabanya ubushyuhe, hamwe nigihe kizaza cyiza cya LED.

Gushakisha ingufu ntabwo ari urugendo gusa - ni impinduramatwara. Kandi buri terambere, twegera hafi yicyatsi kibisi, kirambye ejo.

Kwishyira hamwe kwiza

Tekereza gutera ikirenge mu cya LED yerekana ecran, aho buri pigiseli ipakira punch kandi buri kintu cyose gifite akamaro. Mugihe intera ya pigiseli igabanuka ku muvuduko wihuse, umubare wibikoresho bipakira kuri buri gace kamwe ka skyrockets, bigatera ubucucike bwibice bigize ibice hejuru yimodoka ya LED.

Fata P1.9Gito-pigiseli LEDnk'urugero. Hamwe na scan yayo 15 hamwe na 160 × 90 module, irasaba 180 ihoraho ya disiki ya IC, imiyoboro 45, na 138s. Nibikoresho byinshi bipakiye mumwanya muto, uhindura insinga za PCB mumikino myinshi ya Tetris.

Hamwe ningorabahizi haza ibyago byinshi. Ibice byinshi byuzuyemo ibibazo, uhereye kubudodo bugoye kugeza kugabanuka kwizerwa rya module-yikes! Injira intwari z'isaha: kwishyira hamwe kwinshi umushoferi IC. Hamwe na IC nkeya zisabwa hamwe nu mwanya munini wa PCB wiring, izi chip zujuje ibyifuzo bigenda byiyongera kubishushanyo mbonera neza, byizewe.

Uyu munsi, abatanga chip ya LED IC batanga kwitaba umuhamagaro, basohora imiyoboro 48 ya LED ihoraho ya chip ya shoferi ipakira igikuba gikomeye. Muguhuza imiyoboro ya periferique mu buryo butaziguye muri shoferi IC wafer, borohereza igishushanyo cya PCB kandi bakirinda ububabare bwumutwe buterwa nubuhanga butandukanye.

Umwanzuro

Mwisi yisi ya LED yerekana, aho guhanga udushya bihura nibitekerezo, chip ya LED IC yoroheje ihagaze nkintwari itavuzwe. Iyi chipi itegura simfoni ya pigiseli, ikemeza ko ibara ryose, buri kintu cyose, kimurika hamwe nubwiza buhebuje. Yaba ibyapa byo hanze byo hanze cyangwa ibyumba byo mu nzu byiza, ibyuma bya shoferi bya LED bigize urufatiro rwibintu biboneka bishimisha abumva ku isi yose.

None, niki gitandukanya utwo dukoko? Zubatswe guhuza no guhinduka hamwe nibihe. Kuva muminsi yubupayiniya yerekana amabara abiri yerekanwe kugeza kuri tekinoroji igezweho dufite uyumunsi, chip ya LED IC yagumye kumurongo wo guhanga udushya. Bahinduye uburyo twibonera amashusho, bitangiza mugihe buri pigiseli ivuga inkuru kandi buri cyerekezo gikora uburambe, imbaraga.
