Sisitemu yo kumurika ibinyabiziga -kwamamaza byihuse LED

Mubihe byashize, amatara ya halogen yakunze gutoranywa kugirango amatara yimodoka.Mu myaka yashize, ikoreshwa rya LED mumodoka yose ryatangiye gukura vuba.Ubuzima bwa serivisi yamatara gakondo ya halogen ni amasaha agera kuri 500 gusa, mugihe iy'amatara maremare ya LED agera kumasaha 25000.Ibyiza byo kuramba hafi yemerera amatara ya LED gutwikira ubuzima bwose bwikinyabiziga.
Gukoresha amatara yimbere ninyuma, nkamatara yimbere, itara ryerekana ibimenyetso, itara ryumurizo, itara ryimbere, nibindi, byatangiye gukoresha urumuri rwa LED mugushushanya no guhuza.Ntabwo ari uburyo bwo kumurika ibinyabiziga gusa, ahubwo nuburyo bwo gucana kuva ibikoresho bya elegitoroniki byabaguzi kugeza kubikoresho byo gutangiza uruganda.Ibishushanyo bya LED muri sisitemu yo kumurika bigenda bitandukana kandi bihujwe cyane, bigaragara cyane muri sisitemu yo kumurika imodoka.

Iterambere ryihuse rya LED muri sisitemu yo kumurika imodoka

Nka nkomoko yumucyo, LED ntabwo ifite ubuzima burebure gusa, ariko imikorere yayo yamurika nayo irenze cyane iy'amatara asanzwe ya halogene.Imikorere yamatara ya halogene ni 10-20 Im / W, naho urumuri rwa LED ni 70-150 Im / W.Ugereranije na sisitemu yo gukwirakwiza ubushyuhe butemewe bwamatara gakondo, kunoza imikorere yumucyo bizarushaho kuzigama ingufu kandi neza mumuri.Igihe cyo gusubiza LED nanosekond nacyo gifite umutekano kuruta itara rya halogene igihe cya kabiri cyo gusubiza, ibyo bikaba bigaragara cyane mumwanya wa feri.
Hamwe nogukomeza kunoza igishushanyo cya LED hamwe nurwego rwo guhuza hamwe no kugabanuka gahoro gahoro, isoko yumucyo LED yagenzuwe mubikoresho bya elegitoroniki yimodoka mumyaka yashize kandi itangira kongera uruhare rwayo muri sisitemu yo kumurika ibinyabiziga.Nk’uko imibare ya TrendForce ibigaragaza, igipimo cy’amatara ya LED mu modoka zitwara abagenzi ku isi kizagera kuri 60% mu 2021, kandi igipimo cy’amatara ya LED mu binyabiziga cy’amashanyarazi kizaba kinini, kigere kuri 90%.Biteganijwe ko igipimo cyo kwinjira kiziyongera kugera kuri 72% na 92% muri 2022.
Byongeye kandi, tekinoroji igezweho nkamatara yubwenge, amatara aranga, amatara yikirere yubwenge, kwerekana imodoka ya MiniLED / HDR nayo yihutishije kwinjira muri LED mumatara yimodoka.Uyu munsi, hamwe niterambere ryamatara yimodoka yerekeza kumuntu kugiti cye, kwerekana itumanaho, no gufasha gutwara, yaba abakora imodoka gakondo ndetse nabakora ibinyabiziga byamashanyarazi batangiye gushaka uburyo bwo gutandukanya LED.

Guhitamo LED itwara topologiya

Nka gikoresho gisohora urumuri, LED mubisanzwe igomba kugenzurwa numuzunguruko.Mubisanzwe, iyo umubare wa LED ari munini cyangwa gukoresha ingufu za LED ni nini, birakenewe gutwara (mubisanzwe urwego rwinshi rwo gutwara).Urebye ubudasa bwa LED ikomatanya, ntabwo byoroshye kubashushanya gushushanya umushoferi wa LED.Ariko, birashobora kumvikana ko bitewe nibiranga LED ubwayo, itanga ubushyuhe bunini kandi ikeneye kugabanya imiyoboro ikingira, bityo rero isoko yimikorere ihoraho niyo modoka nziza ya LED.
Ihame rya gakondo ryo gutwara rikoresha ingufu zose za LED muri sisitemu nkigipimo cyo gupima no guhitamo abashoferi ba LED batandukanye.Niba igiteranyo cyimbere cyimbere kiri hejuru yinjiza voltage, noneho ugomba guhitamo kuzamura topologiya kugirango wuzuze ibisabwa na voltage.Niba igiteranyo cyimbere cyimbere kiri munsi yinjiza voltage, ugomba gukoresha intambwe-hasi ya topologiya kugirango utezimbere muri rusange.Ariko, hamwe nogutezimbere ubushobozi bwa LED dimming ibisabwa hamwe no kugaragara kubindi bisabwa, mugihe duhitamo abashoferi ba LED, ntitugomba gutekereza gusa kurwego rwingufu, ahubwo tunasuzume byimazeyo topologiya, imikorere, dimingi nuburyo bwo kuvanga amabara.
Guhitamo topologiya biterwa nu mwanya wihariye wa LED muri sisitemu ya LED.Kurugero, kumurongo muremure hamwe nigitereko cyamatara yimodoka, inyinshi murizo zitwarwa na topologiya-hasi.Iyi disiki yamanutse ni nziza mubikorwa bya bande.Irashobora kandi kugera kubikorwa byiza bya EMI binyuze mugushushanya gukwirakwiza spekitifike inshuro nyinshi.Nibintu byiza cyane bya topologiya muri disiki ya LED.Imikorere ya EMI yo kuzamura LED Drive nayo ni nziza.Ugereranije nubundi bwoko bwa topologiya, ni gahunda ntoya yo gutwara, kandi ikoreshwa cyane mumatara maremare kandi maremare n'amatara maremare yimodoka.
