Amashanyarazi ya LED ni amashanyarazi ahindura amashanyarazi ahindura amashanyarazi mumashanyarazi yihariye hamwe numuyoboro kugirango LED itange urumuri.Mubihe bisanzwe: ibyinjijwe mumashanyarazi ya LED harimo amashanyarazi menshi yumuriro wa AC (nukuvuga ingufu zumujyi), umuyagankuba muke wa DC, umuyagankuba mwinshi DC, imbaraga nke na voltage nyinshi.AC ya Frequency AC (nkibisohoka bya transformateur ya elegitoronike), nibindi

–Kurikije uburyo bwo gutwara:

(1) Ubwoko burigihe

a.Ibisohoka byumuvuduko uhoraho wumurongo wumurongo uhoraho, ariko ibisohoka DC voltage iratandukana murwego runaka hamwe nubunini bwimitwaro irwanya.Gutoya irwanya imitwaro, niko ibisohoka voltage.Ninini irwanya imitwaro, ibisohoka Hejuru ya voltage;

b.Umuzunguruko uhoraho ntutinya umutwaro mugufi, ariko birabujijwe rwose gufungura umutwaro burundu.

c.Nibyiza kumurongo uhoraho wo gutwara ibinyabiziga kugirango utware LED, ariko igiciro kiri hejuru.

d.Witondere ntarengwa kwihanganira agaciro na voltage agaciro gakoreshwa, kagabanya umubare wa LED yakoreshejwe;

(2) Ubwoko bwagenwe:

a.Iyo ibipimo bitandukanye mumuzunguruko wa voltage bigenekereje, ibisohoka voltage irakosorwa, ariko ibisohoka bihinduka hamwe no kwiyongera cyangwa kugabanuka kwumutwaro;

b.Umuzunguruko wa voltage ntuzatinya gufungura imitwaro, ariko birabujijwe rwose kuzunguruka-bigufi imitwaro burundu.

c.LED itwarwa na voltage-stabilisateur ya sisitemu, kandi buri mugozi ugomba kongerwamo imbaraga zikwiye kugirango buri mugozi wa LED werekane urumuri rugereranije;

d.Umucyo uzagira ingaruka kumihindagurikire ya voltage kuva gukosorwa.

–Gushyira ingufu za LED yo gutwara:

(3) Disiki

Porogaramu nyinshi za LED zisaba imikorere idahwitse, nkaLED yamurikacyangwa amatara yububiko.Imikorere ya dimming irashobora kugerwaho muguhindura urumuri no gutandukanya LED.Kugabanya gusa ibyagezweho nigikoresho birashobora guhindukaItaraimyuka ihumanya ikirere, ariko kureka LED ikora muburyo bwo munsi yikigereranyo cyagenwe bizatera ingaruka nyinshi zitifuzwa, nka chromatic aberration.Ubundi buryo bworoshye bwo guhinduranya ni uguhuza pulse ubugari bwa modulisiyo (PWM) mugenzuzi wa LED.Ikimenyetso cya PWM ntabwo gikoreshwa mu buryo butaziguye mu kugenzura LED, ahubwo ni ukugenzura icyerekezo, nka MOSFET, kugirango gitange LED ikenewe kuri LED.Umugenzuzi wa PWM mubusanzwe akora kumurongo uhamye kandi agahindura ubugari bwa pulse kugirango ahuze ninshingano zisabwa.Imashini nyinshi za LED zikoresha PWM kugirango igenzure urumuri rwa LED.Kugirango abantu batumva ko bahindagurika, inshuro ya pulse ya PWM igomba kuba irenga 100HZ.Inyungu nyamukuru yo kugenzura PWM nuko imiyoboro igabanuka binyuze muri PWM isobanutse neza, igabanya itandukaniro ryamabara mugihe LED isohora urumuri.

(4) Drive ya AC

Ukurikije porogaramu zitandukanye, disiki ya AC irashobora kandi kugabanywamo ubwoko butatu: buck, kuzamura, no guhindura.Itandukaniro riri hagati ya AC Drive na DC, usibye gukenera gukosora no kuyungurura ibyinjijwe AC, hariho kandi ikibazo cyo kwigunga no kutigunga uhereye kumutekano.

Umushoferi winjiza AC akoreshwa cyane cyane kumatara ya retrofit: kumatara icumi ya PAR (Parabolike Aluminium Reflector, itara risanzwe kurwego rwumwuga), amatara asanzwe, nibindi, bikora kuri 100V, 120V cyangwa 230V AC Kubitara rya MR16, birakenewe gukora munsi ya 12V AC yinjiza.Bitewe nibibazo bimwe bigoye, nkubushobozi bwo gucogora bwa triac isanzwe cyangwa iyambere iyobora no gukurikira impande za dimmers, hamwe no guhuza ibyuma bya elegitoronike (kuva kumurongo wumurongo wa AC kugirango ubyare 12V AC kubikorwa byamatara ya MR16) Ikibazo cyimikorere (nukuvuga flicker -igikorwa cyubusa), kubwibyo, ugereranije na DC yinjiza umushoferi, umurima ugira uruhare muri AC yinjiza umushoferi biragoye.

Amashanyarazi ya AC (moteri yingenzi) akoreshwa kuri LED, muri rusange binyuze mu ntambwe nko kumanuka, gukosorwa, kuyungurura, guhagarika imbaraga za voltage (cyangwa guhagarara neza), nibindi, kugirango uhindure ingufu za AC mumashanyarazi ya DC, hanyuma utange LED ibereye. unyuze mumashanyarazi abereye Umuyoboro wakazi ugomba kuba ufite imikorere ihindagurika cyane, ingano ntoya nigiciro gito, kandi mugihe kimwe ikemura ikibazo cyo kwigunga.Urebye ingaruka kuri gride yamashanyarazi, kwivanga kwa electromagnetic hamwe nibibazo byingufu nabyo bigomba gukemurwa.Kumashanyarazi mato mato mato na mato mato, imiterere yumuzunguruko mwiza ni imwe yonyine iguruka iguruka igaruka inyuma;kubububasha bukomeye, porogaramu yo guhindura ikiraro igomba gukoreshwa.

–Ibikoresho byo kwishyiriraho ingufu:

Imbaraga zo gutwara zishobora kugabanywa mumashanyarazi yo hanze kandi yubatswe mumashanyarazi ukurikije aho ushyira.

(1) Amashanyarazi yo hanze

Nkuko izina ribigaragaza, amashanyarazi yo hanze nugushiraho amashanyarazi hanze.Mubisanzwe, voltage iri hejuru cyane, ibyo bikaba byangiza umutekano kubantu, kandi harakenewe amashanyarazi yo hanze.Itandukaniro hamwe n’amashanyarazi yubatswe ni uko amashanyarazi afite igikonjo, kandi amatara yo kumuhanda ni rusange.

(2) Amashanyarazi yubatswe

Amashanyarazi yashyizwe mumatara.Mubisanzwe, voltage iba mike ugereranije, kuva 12v kugeza 24v, ibyo bikaba bidafite umutekano muke kubantu.Iyi isanzwe ifite amatara.
