NIKI LED?

LED ni ngufi kuri Diode Yumucyo.LED itanga urumuri biturutse kumashanyarazi.Bizwi kandi nka "itara rikonje" nkuko, bitandukanye nubushaje bwakera bwakera, urumuri ntirukorwa no gushyushya icyuma.Ku rundi ruhande, diode itanga urumuri iyo runyuze mu bice bibiri byihariye bya silicon.Nimwe muburyo bukoresha ingufu kandi bukoresha ingufu zitanga urumuri.

LED igizwe nibikoresho bikomeye bidafite ibice byimukanwa kandi akenshi ibumbabumbwa muri plastiki iboneye.Ibi bitanga igihe kirekire.Iyo LED iriho, isohora ubushyuhe bwa zeru.Ibi bigabanya ikibazo cyo gukonjesha ibice bya elegitoroniki.

LED ya mbere yakozwe n’Umurusiya wahimbye Oleg Losev mu 1927. Mu myaka myinshi, byashobokaga gusa kubyara LED, itukura n’umuhondo.Iyi diode yabonetse mubintu byose kuva kugenzura kure kugeza kumaradiyo yisaha.

Mu 1994 ni bwo umuhanga mu Buyapani Shuji Nakamura yashoboye kwerekana LED ikora neza.LED yera nicyatsi kibisi yahise ikurikiraho, ishyiraho urufatiro rwa revolution ya LED twabonye mumuri no kwerekana ikoranabuhanga.

NI GUTE UMURIMO UKORESHEJWE UKORA?

LED yerekana igizwe na LED nyinshi zegeranye cyane.Muguhindura urumuri rwa buri LED, diode ifatanije gukora ishusho kumurongo.

Kurema ibara ryiza ryishusho, amahame yo kongeramo amabara avanga arakoreshwa, aho amabara mashya arema mukuvanga urumuri mumabara atandukanye.LED yerekana igizwe numutuku, icyatsi nubururu LED yashizwe muburyo butajegajega.Aya mabara atatu arahuza kugirango akore pigiseli.Muguhindura ubukana bwa diode, miriyari y'amabara irashobora gushirwaho.Iyo urebye kuri LED ya ecran kuva kure, umurongo wa pigiseli y'amabara igaragara nkishusho.

RGB NIKI?

RGB ni ngufi kuri Umutuku, Icyatsi n'Ubururu.Nibara ryibara rikoresha ukuri ko amabara yose agaragarairashobora kuvangwa kuva muribi bitatu shingiroamabara.Ikoreshwa hafi yubwoko bwose bwerekana, harimo LED yerekana.

NIKI SMD?

SMD bisobanura Igikoresho cyo hejuru cyubuso.Ibi nibikoresho bya elegitoronike bishyirwa hejuru kumurongo wacapwe - kandi ntabwo nkuko byari bimeze mbere mugurisha icyuma kumpande yumwanya wumuzunguruko.

Muri LED yerekana ikoranabuhanga, igitekerezo cya SMD gikoreshwa muburyo butandukanye.Iyerekana rya SMD ni LED yerekana aho diyode itukura, icyatsi nubururu iba yashizwe mumashanyarazi ntoya ya plastike iba hejuru yubuso ku mbaho ​​zacapwe zerekana.Iyo diode ikusanyirijwe muri ubu buryo, ifata umwanya muto cyane, bigatuma bishoboka kubyara disikuru ifite umwanya muto hagati ya diode no gukemura neza.

NUBUBASHA BENSHI BUKORESHEJWE LED

LED ni tekinoroji ikoresha ingufu nyinshi, niyo mpamvu ikoreshwa ryinshi ryogukoresha ingufu za LED muri iki gihe.Ingano yimbaraga diode mugukoresha LED yerekana biterwa nubwoko bwerekana, umucyo nikoreshwa.

Hariho ubwoko bwinshi butandukanye bwa LED na disikuru.Imbaraga zikoreshwa mubyerekanwe murugo, kurugero, zizaba zitandukanye nicyapa cyo hanze cyo hanze, kigomba kugaragara kumurasire yizuba.Umucyo wo kwerekana nawo ni ikintu gikomeye.Amashusho agomba kuba asobanutse, ariko urumuri ruva kumurongo ntirukwiye.LED yerekana hanze igomba kuba yaka cyane kumanywa kuruta igihe umwijima uguye.

Ibyerekanwe nabyo bifite ingaruka.LED yerekana amashusho mugukingura no guhindura urumuri rwa diode y'amabara.Ishusho yera rwose hamwe ninyandiko yumukara rero izakenera izindi nyinshi zimurikirwa - hamwe nimbaraga nyinshi - kuruta inyandiko yera kumurongo wirabura.

KUGARAGAZA GUTE?

Biragoye kuvuga ikintu cyihariye kijyanye nubuzima bwa LED yerekana nkuko ibintu byinshi biza gukina.Ariko, hamwe no kubungabunga neza, kwerekana birashobora kumara imyaka irenga icumi.Kimwe nubwoko bwose bwa elegitoroniki, igihe cyo kubaho nacyo kigira ingaruka kumikoreshereze ya buri munsi nibidukikije bikikije ibyerekanwa.Amashusho yoroheje nurwego rwo hejuru rwurumuri rwambara cyane kurugero kuruta amashusho yijimye kandi urwego rwo hasi rwurumuri.Ibintu nkubushuhe nibirimo umunyu mwikirere nabyo birashobora gukina.

Mugihe cyimibereho yubuzima bwa LED, urumuri rusohoka muri diode ruzagabanuka.Nukuntu biterwa nubwoko nigisekuru cya diode.LED nyinshi zerekana ntizigera zikoresha urumuri rwuzuye, kugabanuka rero ntibikunze kuba ikibazo.

NIKI CYIZA CYA PIXEL KANDI KUGARAGAZA UMWANZURO?

Intera iri hagati ya LED yerekana diode igena imiterere yerekana.Intera igana hagati yitsinda ryabaturanyi ripimirwa hagati ya buri tsinda rya diode itukura, icyatsi nubururu.Intera izwi nka pigiseli.Buri tsinda rya diode rigira pigiseli.

Niba LED yerekana ifite pigiseli ya cm 1, hashobora kuba pigiseli 100 x 100 kuri metero kare yerekana.Gukemura kwerekanwa gutangwa nkumubare wimibare yerekana ubugari nuburebure muri pigiseli.Niba ufite ecran ya metero 6 x 8 na cm 1 mukibanza cya pigiseli, ifite ibyemezo bya 600 x 800 pigiseli.

Hano hari LED ya ecran ifite pigiseli yahantu hose kuva kuri santimetero nyinshi kugeza kuri milimetero imwe.

NIKI GIKORWA NAKWIYE GUHITAMO?

Imyanzuro ukeneye kugirango LED yerekanwe biterwa nintera yo kureba.Ni ubuhe burebure abakwumva bazareba ibyerekanwa?Niba uri hafi ya LED yerekana neza (kure ya diode), bizagorana kubona ibiri kumurongo.

Hano mubisanzwe hari isano hagati yo kwerekana ibyemezo nigiciro.Hejuru yo gukemura, niko diode nyinshi ziri kuri m2 - nuko igiciro cya m2 kiri hejuru.

Niba urimo gushiraho ikimenyetso cya digitale kumuhanda munini cyangwa kuruhande rwinyubako, bizagaragara kure.Hano, kwerekana-hejuru-kwerekana kwerekana ntibyari ngombwa - kandi bihenze bitari ngombwa.Niba ari igorofa kurwego rwo hagati rwagati rwububiko, abumva bazakwegera cyane.Hano, imyanzuro ihanitse yerekana ikora neza.

Amategeko meza yintoki kuri LED yerekana ni: 1 mm pigiseli ikibanza kuri buri metero yo kureba intera.
