Nyuma yimyaka yiterambere, bisanzwe bisanzwe anode LED yakoze urunigi ruhamye rwinganda, rutera kwamamara kwa LED. Ariko, ifite kandi ibibi byubushyuhe bwo hejuru bwa ecran no gukoresha ingufu nyinshi. Nyuma yo kugaragara kwa cathode LED yerekana tekinoroji yo gutanga amashanyarazi, yakwegereye cyane kumasoko ya LED. Ubu buryo bwo gutanga amashanyarazi burashobora kugera ku mbaraga ntarengwa zo kuzigama 75%. None ni ubuhe bwoko bwa cathode LED yerekana tekinoroji yo gutanga amashanyarazi? Ni izihe nyungu z'ikoranabuhanga?
1. Cathode LED isanzwe ni iki?
"Rusange cathode" bivuga uburyo busanzwe bwo gutanga amashanyarazi ya cathode, mubyukuri ni tekinoroji yo kuzigama ingufu kuri ecran ya LED. Bisobanura gukoresha uburyo busanzwe bwa cathode kugirango uhindure LED yerekana ecran, ni ukuvuga R, G, B (umutuku, icyatsi, ubururu) yamasaro ya LED yamashanyarazi akoreshwa ukwe, kandi amashanyarazi na voltage byahawe neza kuri R , G, B itara ryamatara uko ryakabaye, kuberako amashanyarazi meza yo gukora hamwe numuyoboro usabwa na R, G, B (umutuku, icyatsi, ubururu) amatara atandukanye. Muri ubu buryo, ikigezweho kibanza kunyura mumasaro yamatara hanyuma kikagera kuri electrode mbi ya IC, igabanuka ryumubyigano wimbere rizagabanuka, kandi imyigaragambyo yimbere izaba nto.
2. Ni irihe tandukaniro riri hagati ya cathode isanzwe na LED ya anode isanzwe?
①. Uburyo butandukanye bwo gutanga amashanyarazi:
Uburyo rusange bwo gutanga amashanyarazi ya cathode nuko iyambere ibanza kunyura mumasaro yamatara hanyuma ikajya kuri pole mbi ya IC, igabanya umuvuduko wimbere wimbere hamwe no kurwanya imbere imbere.
Anode isanzwe ni uko ikigezweho kiva mu kibaho cya PCB kijya ku isaro ryamatara, kandi kigatanga ingufu kuri R, G, B (umutuku, icyatsi, ubururu) kimwe, biganisha ku ntera nini ya voltage igabanuka mu muzunguruko.
②. Amashanyarazi atandukanye yo gutanga amashanyarazi:
Cathode isanzwe, izatanga amashanyarazi na voltage kuri R, G, B (umutuku, icyatsi, ubururu) ukwayo. Umuvuduko wa voltage wibitereko bitukura, icyatsi nubururu biratandukanye. Umuvuduko ukenewe wamashanyarazi yamatara atukura agera kuri 2.8V, naho voltage isabwa kumatara yubururu-icyatsi kibisi ni 3.8V. Amashanyarazi nkaya arashobora kugera kumashanyarazi yukuri no gukoresha ingufu nke, kandi ubushyuhe butangwa na LED mugihe cyakazi ni buke cyane.
Ku rundi ruhande, anode isanzwe, itanga R, G, B (umutuku, icyatsi, ubururu) voltage irenze 3.8V (nka 5V) kugirango itange amashanyarazi. Muri iki gihe, voltage yabonetse itukura, icyatsi nubururu ni 5V ihuriweho, ariko imbaraga nziza zakazi zisabwa namasaro atatu yamatara ziri munsi ya 5V. Ukurikije imbaraga za formula P = UI, mugihe ikigezweho kidahindutse, niko voltage nini, niko imbaraga nyinshi, aribyo, niko gukoresha ingufu nyinshi. Mugihe kimwe, LED nayo izatanga ubushyuhe bwinshi mugihe cyakazi.
UwitekaIsi Yagatatu-Igisekuru Hanze LED Yamamaza Mugaragaza Yakozwe na XYGLEDKwemera cathode. Ugereranije na 5V itukura, icyatsi, nubururu bwa diode itanga urumuri, pole nziza ya chip itukura LED ni 3.2V, mugihe LED nicyatsi nubururu LED 4.2V, igabanya ingufu byibuze 30% kandi ikerekana ingufu nziza- kuzigama no kugabanya-imikorere.
3. Kuki cathode isanzwe LED itanga ubushyuhe buke?
Uburyo budasanzwe bwa cathode itanga amashanyarazi ya ecran ikonje ituma LED yerekana itanga ubushyuhe buke nubushyuhe buke bwiyongera mugihe gikora. Mubihe bisanzwe, muburyo bwera buringaniye kandi mugihe ukina videwo, ubushyuhe bwa ecran ikonje buri munsi ya 20 ℃ munsi ugereranije nubusanzwe hanze LED yerekana icyerekezo kimwe. Kubicuruzwa byibisobanuro bimwe kandi kumurabyo umwe, ubushyuhe bwa ecran ya cathode isanzwe ya LED yerekanwe burenze dogere 20 munsi yibyo bisanzwe bisanzwe anode LED yerekana ibicuruzwa, kandi ingufu zikoreshwa zirenze 50% munsi yibyo y'ibisanzwe bisanzwe anode LED yerekana ibicuruzwa.
Ubushyuhe bukabije hamwe n’ingufu zikoreshwa mu kwerekana LED byahoze ari ibintu byingenzi bigira ingaruka ku mibereho ya serivisi y’ibicuruzwa byerekana LED, kandi "icyerekezo rusange cya cathode LED" gishobora gukemura neza ibyo bibazo byombi.
4. Ni izihe nyungu zo kwerekana cathode LED yerekana?
①. Amashanyarazi nyayo nukuri azigama ingufu:
Igicuruzwa gisanzwe cya cathode gikoresha uburyo bunoze bwo kugenzura amashanyarazi, hashingiwe ku miterere itandukanye y’amashanyarazi y’amabara atatu yibanze ya LED itukura, icyatsi nubururu, kandi ifite ibikoresho byubwenge bwa IC byerekana ubwenge hamwe nuburyo bwigenga bwigenga kugirango butange neza voltage zitandukanye. kuri LED n'umuzunguruko wa moteri, kugirango ibicuruzwa bikoresha ingufu biri munsi ya 40% ugereranije nibicuruzwa bisa kumasoko!
②. Kuzigama ingufu nyazo bizana amabara nyayo:
Uburyo busanzwe bwo gutwara cathode LED burashobora kugenzura neza voltage, igabanya gukoresha amashanyarazi no kubyara ubushyuhe. Uburebure bwa LED ntibugenda bukomeza gukora, kandi ibara ryukuri ryerekanwe neza!
③. Kuzigama ingufu nyazo bizana ubuzima burebure:
Ingufu zikoreshwa ziragabanuka, bityo bikagabanya cyane izamuka ryubushyuhe bwa sisitemu, bikagabanya neza amahirwe yo kwangirika kwa LED, kuzamura umutekano no kwizerwa bya sisitemu yose yerekana, no kwagura ubuzima bwa sisitemu.
5. Ni ubuhe buryo bwo kwiteza imbere bwa tekinoroji ya cathode?
Ibicuruzwa byunganira bifitanye isano na cathode LED yerekana ikoranabuhanga, nka LED, amashanyarazi, umushoferi IC, nibindi, ntabwo bikuze nkurunani rusanzwe rwa anode LED. Mubyongeyeho, urukurikirane rusanzwe rwa cathode IC ntiruzura muri iki gihe, kandi ingano rusange ntabwo ari nini, mugihe anode isanzwe iracyafite 80% yisoko.
Impamvu nyamukuru yiterambere ryihuse rya tekinoroji ya cathode nigiciro kinini cyumusaruro. Ukurikije ubufatanye bwambere bwo gutanga amasoko, cathode isanzwe isaba ubufatanye bwihariye kumpera zose zinganda zinganda nka chip, gupakira, PCB, nibindi, bihenze.
Muri iki gihe cyo guhamagarira abantu benshi kuzigama ingufu, kugaragara kwa cathode isanzwe ibonerana LED yerekanwe byahindutse ingingo yo gushyigikirwa ninganda. Nubwo bimeze bityo ariko, haracyari inzira ndende yo kugera ku ntera yuzuye no kuyishyira mu bikorwa mu buryo bunini, bisaba imbaraga zihuriweho n’inganda zose. Nicyerekezo cyiterambere ryokuzigama ingufu, ecran rusange ya cathode LED yerekana gukoresha no gukoresha amashanyarazi. Kubwibyo, kuzigama ingufu bifitanye isano ninyungu za LED yerekana abakoresha ecran no gukoresha ingufu zigihugu.
Uhereye kuri ubu, cathode isanzwe LED yerekana ingufu zo kuzigama ntizongera igiciro cyane ugereranije na ecran isanzwe yerekana, kandi izigama ibiciro mugukoresha nyuma, yubahwa cyane nisoko.
