Nyuma yimyaka yiterambere, imigenzo gakondo ya anode LED yerekanwe yakoze urwego ruhamye rwinganda, ibyo bikaba byaratumye abantu bamenyekanisha LED.Ariko, ifite kandi ibibi, ubushyuhe bukabije bwa ecran no gukoresha ingufu nyinshi.Nyuma yo kugaragara kwa cathode LED yerekana ingufu za tekinoroji, yakwegereye abantu benshi kumasoko ya LED.Ubu buryo bwo gutanga amashanyarazi bushobora kugera ku kuzigama ingufu zingana na 75%, none ni ubuhe buryo bwo gukoresha amashanyarazi ya cathode LED yerekana?Ni izihe nyungu z'ikoranabuhanga?
Ni izihe nyungu zikoranabuhanga ryo gutanga amashanyarazi ya cathode isanzwe LED yerekana
1. Ni ubuhe bwoko bwa cathode LED yerekana?
"Rusange cathode" bivuga uburyo busanzwe bwo gutanga amashanyarazi.Mubyukuri, ubu ni tekinoroji yo kuzigama ingufu kuri LED yerekana.Yerekeza ku gukoresha cathode isanzwe kugirango yerekane LED yerekana.B. voltage, hamwe numuyoboro uratandukanye, Kubwibyo, icyuma kizabanza kunyura mumasaro yamatara, hanyuma kigere kuri pole mbi ya IC, bigabanye umuvuduko wimbere wimbere kandi bigabanye imbaraga zo guhangana imbere.
2. Ni irihe tandukaniro riri hagati ya cathode isanzwe hamwe na anode LED yerekana?
①.Uburyo butandukanye bwo gutanga amashanyarazi:
Uburyo bukoreshwa bwa cathode uburyo bwo gutanga amashanyarazi ni uko ikigezweho kibanza kunyura mumasaro yamatara hanyuma kikagera kuri pole mbi yumuzunguruko uhuriweho, kuburyo igitonyanga cyimbere cyimbere kiba gito kandi kuri-kurwanya kikaba gito.
Inzira ya anode isanzwe iva mubuyobozi bwa PCB ikagera kumasaro yamatara, kandi igatanga imbaraga kuri R, G, B (umutuku, icyatsi, ubururu), kugirango umuvuduko wimbere wumuzunguruko ube munini.
②.Umuvuduko w'amashanyarazi uratandukanye:
Cathode isanzwe, itanga amashanyarazi na voltage kuri R, G, B (umutuku, icyatsi, ubururu).LED, umutuku, icyatsi nubururu bifite voltage zitandukanye zisabwa.Umuvuduko wamasaro yumutuku utukura ugera kuri 2.8V, naho voltage yamasaro yubururu nicyatsi kibisi ni 3.8V, aya mashanyarazi arashobora kugera kumashanyarazi neza no gutanga amashanyarazi.Bitewe nigihombo gito, ubushyuhe butangwa na LED mugihe cyo gukora ni buke cyane.
Cathode isanzwe igomba guha R, G, B (umutuku, icyatsi, ubururu) amashanyarazi ahuriweho arenga 3.8V (nka 5V).Muri iki gihe, voltage yabonetse kubutuku, icyatsi nubururu ihwanye na 5V, mugihe umutuku, icyatsi, Umuvuduko mwiza wakazi usabwa namasaro atatu yubururu ari munsi ya 5V.Ukurikije ingufu za formula P = UI, mubihe bihoraho byubu, hejuru ya voltage, niko imbaraga nini, aribyo, niko gukoresha ingufu nyinshi, mugihe LED yerekana ikora Ubushyuhe bwinshi butangwa mubikorwa.
3. Kuki ubushyuhe bwa cathode isanzwe LED yerekana munsi?
Uburyo budasanzwe bwa cathode itanga amashanyarazi ya ecran ikonje ituma LED yerekana inzira itanga ubushyuhe buke nubushyuhe bwo hasi.Mubihe bisanzwe, mugihe cyo kuringaniza cyera no gukina amashusho, ubushyuhe bwa ecran ikonje buri munsi ya 20 ° C munsi yubwa gakondo yo hanze LED yerekana icyitegererezo kimwe.Mubisobanuro bimwe hamwe nubucyo bumwe, ubushyuhe bwa ecran ya cathode isanzwe LED yerekana ni hejuru ya dogere 20 munsi yibicuruzwa bisanzwe byerekana anode LED, kandi gukoresha ingufu biri munsi ya 50% ugereranije nibicuruzwa bisanzwe bya anode LED.
Ubushyuhe bwo hejuru bwa LED yerekana ecran hamwe no gukoresha ingufu nyinshi byahoze ari ibintu byingenzi bigira ingaruka mubuzima bwa serivisi ya LED yerekana."Rusange cathode LED yerekana" irashobora gukemura ibyo bibazo byombi.
4. Ni izihe nyungu za cathode isanzwe LED yerekana?
e amashanyarazi azigama ingufu rwose:
Ibicuruzwa bisanzwe bya cathode bifata tekinoloji igenzura neza, ukurikije ibintu bitandukanye bya optoelectronic biranga amabara atatu yibanze ya LED umutuku, icyatsi nubururu, uhujwe na sisitemu yo kugenzura ubwenge ya IC hamwe nuburyo bwigenga, imbaraga zitandukanye za LED hamwe n’umuzunguruko utwara neza. yagabanijwe, kugirango ingufu zikoreshwa mubicuruzwa ziri hejuru.Ibicuruzwa nkibi ku isoko bizigama hafi 40%!
②.Kuzigama ingufu nyazo bizana ibara nyaryo:
Uburyo bukoreshwa bwa cathode LED uburyo bwo gutwara bushobora kugenzura neza voltage, mugihe kugabanya gukoresha ingufu no kubyara ubushyuhe, uburebure bwumurongo wa LED ntibuzagenda mugihe gikomeza, kandi ibara ryukuri rirashobora kugaragara neza!
③.Kuzigama ingufu nyazo bizana kuramba:
Ingufu zikoreshwa ziragabanuka, izamuka ryubushyuhe bwa sisitemu riragabanuka cyane, amahirwe yo kwangirika kwa LED aragabanuka neza, ituze hamwe nubwizerwe bwa sisitemu yose yerekanwe biratera imbere, kandi ubuzima bwa serivisi bwa sisitemu buragurwa cyane.
5. Ni ubuhe buryo bugezweho mu ikoranabuhanga ribi?
Bifitanye isano na cathode LED yerekana tekinoroji nka LED, ibikoresho by'amashanyarazi, hamwe na shoferi ya IC, ntabwo ikuze nkurunigi rwa Ram LED.Mubyongeyeho, urutonde rusange rwa cathode IC rwuzuye ntabwo rwuzuye, kandi ibicuruzwa muri rusange ntabwo ari binini.Ram aracyafite 80% yisoko.
Impamvu nyamukuru yiterambere ryihuta rya tekinoroji ya cathode muri iki gihe nigiciro kinini cyumusaruro.Ukurikije ubufatanye bwambere bwo gutanga amasoko, cathode isanzwe isaba ubufatanye bwihariye kumpera zose zurwego rwinganda nka chip, gupakira, na PCBs, kandi ikiguzi ni kinini.
Muri iki gihe gikenewe cyane mu kuzigama ingufu, kugaragara kwa LED isanzwe igaragara mu mucyo byahindutse ingingo yo gushyigikira inganda.Nubwo bimeze bityo ariko, haracyari inzira ndende yo kugera ku ntera yuzuye no kuyishyira mu bikorwa mu buryo bunini, kandi imbaraga z’inganda zose zirasabwa.Ubusanzwe cathode LED yerekana ikubiyemo gukoresha ingufu z'amashanyarazi n'ibiciro byo gukora, aribwo buryo bwiterambere bwo kuzigama ingufu.Kubwibyo, kuzigama ingufu no kugabanya ibicuruzwa bifitanye isano ninyungu zabakoresha LED berekana no gukoresha ingufu zigihugu.
Urebye uko ibintu bimeze ubu, cathode isanzwe LED yo kuzigama ingufu ntizongera igiciro cyane ugereranije niyerekanwa gakondo, kandi izanabika amafaranga mugukoresha ejo hazaza, yakirwa neza nisoko.
