UwitekaLED itanga amashanyaraziihindura amashanyarazi muri voltage yihariye nubu kugirango itware voltage ihindura LED.Mubisanzwe: iyinjizwa ryaLED itanga amashanyaraziikubiyemo amashanyarazi menshi yumuriro wa AC, voltage nkeya DC, voltage nini ya DC, voltage nkeya cyane ya AC, nibindi. Uyu munsi rero nzakwereka LED ihora itanga amashanyarazi.
Amashanyarazi ahorahouburyo bwo gutwara
Amashanyarazi ahoraho
1. Nyuma yumubyigano uhoraho wumurongo ugena ibipimo bitandukanye, bisohora voltage ihamye, ariko ibisohoka bihinduka hamwe no kwiyongera cyangwa kugabanuka kwumutwaro.
2. Nubwo umuyagankuba uhindagurika wumuzunguruko udatinya gufungura imizigo, birabujijwe rwose guhinduranya umuzigo mugufi.
3. Guhindura imbaraga za voltage nyuma yo gukosorwa bizagira ingaruka kumucyo wa LED.
4. Kugirango buri mugozi wa LED utwarwa na voltage stabilizing circuit yerekana urumuri rumwe, hagomba kongerwaho rezistor ikwiye.
5. Umuzunguruko uhoraho wa voltage ninziza cyane yo gutwara LED, kandi voltage ihoraho niyo nzira izaza.
Ibirangaamashanyarazi ahoraho
(1) Kwizerwa cyane
Cyane cyane nkamashanyarazi yo gutwara amatara yo kumuhanda LED, yashyizwe hejuru murwego rwo hejuru, bigatuma kubungabunga bitoroha kandi bihenze.
(2) Gukora neza
LED nigicuruzwa kizigama ingufu, kandi imikorere yumuriro wamashanyarazi igomba kuba hejuru.Ni ngombwa cyane gukwirakwiza ubushyuhe aho ihurira aho amashanyarazi ashyirwa imbere muri luminaire.Imikorere yo gutanga amashanyarazi ni myinshi, gukoresha ingufu ni nto, kandi ubushyuhe butangwa mu itara ni buto, ari nabwo bugabanya ubushyuhe bw’itara.Nibyiza gutinza kwangirika kwurumuri rwa LED.
(3) Impamvu zikomeye
Imbaraga nizo zisabwa ingufu za gride yumutwaro.Mubisanzwe, nta bipimo byateganijwe kubikoresho byamashanyarazi biri munsi ya watt 70.Nubwo ingufu nke zikoreshwa mumashanyarazi imwe ifite ingufu nkeya ntacyo zizagira kuri gride yamashanyarazi, urumuri rwinshi rukoreshwa nijoro hamwe nuburemere bwimitwaro isa nayo bizatera umwanda ukomeye kuri gride.Kuri 30-40 watt LED yo gutwara amashanyarazi, havugwa ko hashobora kuba hari ibipimo ngenderwaho bisabwa kubintu byamashanyarazi mugihe cya vuba.
(4) Kurinda
Ubushobozi bwa LED bwo kwihanganira imishwarara burakennye cyane cyane ubushobozi bwayo bwo guhangana na voltage ihinduka.Gushimangira uburinzi muri kariya gace nabyo ni ngombwa.Amatara amwe ya LED yashyizwe hanze, nk'amatara yo kumuhanda LED.Bitewe no gukora imitwaro ya gride hamwe no kwinjiza inkuba, imirasire itandukanye izatera muri sisitemu ya gride, kandi bimwe bizatera kwangiza LED.Niyo mpamvu, hasesenguwe ko amashanyarazi atwara “Zhongke Huibao” agomba kugira intege nke mukurinda indwara.Kubijyanye no gusimbuza kenshi ibikoresho byamashanyarazi n'amatara, amashanyarazi ya LED agomba kuba afite ubushobozi bwo guhagarika ubwinjiriro bwimitsi no kurinda LED kwangirika.
(5) Igikorwa cyo kurinda
Usibye ibikorwa bisanzwe byo kurinda amashanyarazi, nibyiza kongeramo ubushyuhe bwa LED ibitekerezo bibi kubisohoka buri gihe kugirango wirinde ubushyuhe bwa LED kuba hejuru cyane;igomba kubahiriza amabwiriza yumutekano nibisabwa na electronique.
Amashanyarazi ahorahoirashobora kugabanywamo ibyiciro bitandatu ukurikije imiterere yumuzunguruko
1. Impinduramatwara isanzwe intambwe-hasi:
Ibyiza byubwoko nkubu bwo gutanga amashanyarazi nubunini bwayo.Ikibi ni uko kiremereye muburemere kandi imbaraga zingufu nazo ziri hasi cyane, muri rusange hagati ya 45% na 60%.Kuberako kwizerwa atari hejuru, ntibikoreshwa gake.
2. Kugabanya ingufu za capacitori:
Ubu bwoko bwamashanyarazi ya LED bugira ingaruka byoroshye kumihindagurikire ya voltage, kandi amashanyarazi ni make.Ntibikwiye gukoresha LED mugihe irimo gucana, kuko umuzenguruko ugabanya voltage binyuze muri capacitor.Iyo ikoreshejwe mugucana, bitewe ningaruka zo kwishyuza no gusohora, umuyaga uhita unyura muri LED Nini cyane kandi irashobora kwangiza chip byoroshye.
3. Transformator ya elegitoronike intambwe-hasi:
Inenge ziyi miterere yo gutanga amashanyarazi nubushobozi buke bwo guhindura, umuvuduko muto wa voltage, muri rusange 180 ~ 240V, hamwe no kwivanga kwinshi.
4. Kugabanya ingufu za Resistor:
Imbaraga zingufu zubu buryo bwo gutanga amashanyarazi ziri hasi cyane, kandi kwizerwa kwa sisitemu nabyo biri hasi.Kuberako umuzunguruko ugabanya voltage binyuze mumurwanya, birahungabanywa cyane nimpinduka za voltage ya gride, ntabwo rero byoroshye gutanga amashanyarazi yagenwe, kandi rezistor igabanya voltage ubwayo ikoresha igice kinini cyingufu.
5. RCC kumanura amashanyarazi kumashanyarazi:
Ibyiza byubu bwoko bwamashanyarazi ya LED ni intera yagutse ya voltage ihagaze neza kandi ikora neza cyane, ishobora kuba 70% kugeza 80%, kandi ikoreshwa cyane.Ingaruka nyamukuru ni uko guhinduranya inshuro bigoye kugenzura, coefficente yimitwaro ya voltage nini, kandi guhuza imizigo ni bibi mubihe bidasanzwe.
6. PWM yagenzuye amashanyarazi:
Kugeza ubu, LED amashanyarazi yatanzwe hamwe na PWM igenzura nibyiza kuko ibisohoka voltage cyangwa amashanyarazi yaya mashanyarazi ahinduka cyane.Imbaraga zo guhindura imbaraga ziri hejuru cyane, mubisanzwe hejuru ya 80% ~ 90%, hamwe nibisohoka voltage numuyoboro birahagaze neza.Ubu buryo bwo gutanga amashanyarazi ya LED bugizwe ahanini nibice bine: gukosora ibyinjijwe no kuyungurura igice, gusohora ibyasohotse no kuyungurura, igice cyo kugenzura amashanyarazi ya PWM, no guhindura igice cyo guhindura ingufu.Byongeye kandi, uyu muzunguruko ufite ingamba zuzuye zo kurinda kandi ni amashanyarazi yizewe cyane.
Ibiranga umunani biranga imikorere yaamashanyarazi ahoraho
Ukurikije amategeko yo gukoresha amashanyarazi ya gride yumuriro nibisabwa biranga amashanyarazi ya LED, icyenda gikurikira gikwiye kwitabwaho muguhitamo no gushushanya amashanyarazi ya LED:
1. Kwizerwa cyane, cyane cyane amashanyarazi yo gutwara amatara yo kumuhanda LED, ashyirwa murwego rwo hejuru, bigatuma kubungabunga bitoroha kandi bihenze.
2. LED ikora neza cyane nibicuruzwa bizigama ingufu, kandi imikorere yumuriro wo gutwara igomba kuba hejuru.Ibi nibyingenzi byingenzi mubyubatswe aho amashanyarazi ashyirwa mumatara.Kuberako imikorere ya LEDs igabanuka uko ubushyuhe bwa LED bwiyongera, gukwirakwiza ubushyuhe bwa LED ni ngombwa cyane.Imikorere yo gutanga amashanyarazi ni myinshi, gukoresha ingufu ni nto, kandi ubushyuhe butangwa mu itara ni buto, ari nabwo bugabanya ubushyuhe bw’itara.Nibyiza gutinza kwangirika kwurumuri rwa LED.
3．Ibintu byinshi byingufu Imbaraga nigisabwa cya gride kumutwaro.Mubisanzwe, nta bipimo byateganijwe kubikoresho byamashanyarazi biri munsi ya watt 70.Nubwo imbaraga nkeya yibikoresho byamashanyarazi imwe ifite ingufu nkeya ntacyo bizahindura kuri gride yamashanyarazi, niba buriwese acana amatara nijoro kandi ubwoko bumwe bwumutwaro bukaba bwibanze cyane, bizatera umwanda mwinshi kuri gride.Kuri 30-40 watt ya LED itanga amashanyarazi, havugwa ko hashobora kuba hari ibipimo ngenderwaho bisabwa kubintu byamashanyarazi mugihe cya vuba.
4．Kurinda Surge ubushobozi bwa LED bwo kwihanganira imivurungano burakennye cyane cyane ubushobozi bwayo bwo guhangana na voltage yinyuma.Gushimangira uburinzi muri kariya gace nabyo ni ngombwa.Amatara amwe ya LED yashyizwe hanze, nk'amatara yo kumuhanda LED.Bitewe no gukora imitwaro ya gride hamwe no kwinjiza inkuba, imirasire itandukanye izatera muri sisitemu ya gride, kandi bimwe bizatera kwangiza LED.Kubwibyo, LED itanga amashanyarazi igomba kuba ifite ubushobozi bwo guhagarika ubwiyongere bukabije no kurinda LED kwangirika.
5. Igikorwa cyo gukingira Usibye ibikorwa bisanzwe byo kurinda amashanyarazi, nibyiza kongeramo ubushyuhe bwa LED ibitekerezo bibi kumasoko ahoraho kugirango wirinde ubushyuhe bwa LED kuba hejuru cyane.
6. Mu rwego rwo kurinda, niba itara ryarashyizwe hanze, imiterere y’amashanyarazi igomba kuba idafite amazi kandi itagira amazi, kandi ikariso yo hanze igomba kuba idashobora kwihanganira urumuri.
7. Ubuzima bwo gutanga amashanyarazi bugomba guhuza ubuzima bwa LED.
8. Ugomba kubahiriza amabwiriza yumutekano hamwe nibisabwa na electromagnetic.
Mugihe ikoreshwa rya LED rigenda ryiyongera, imikorere ya LED yo gutwara amashanyarazi izarushaho kuba nziza kubisabwa LED.
Kubibazo byibicuruzwa, nyamuneka rebaurupapuro rwibicuruzwa, urahawe ikazetwandikireukoresheje amakuru y'itumanaho hepfo, tuzagusubiza muri 24.
