Ingufu za LED drive ni igikoresho gihindura ingufu zikoreshwa mu guhindura ingufu zikoreshwa mu miyoboro yihariye y'amashanyarazi n'amashanyarazi kugira ngo LED itange urumuri. Mu bihe bisanzwe: ingufu zikoreshwa mu miyoboro ya LED zirimo ingufu za AC (ni ukuvuga ingufu zo mu mujyi), DC (voltage nkeya), DC (voltage nkeya), DC (voltage nkeya), voltage nkeya n'amashanyarazi menshi. AC (nk'umusaruro w'icyuma gihindura amashanyarazi), n'ibindi.

– Dukurikije uburyo bwo gutwara:

(1) Ubwoko bw'umuriro uhoraho

a. Umuvuduko w'amashanyarazi uhoraho ukoreshwa mu gukwirakwiza umuriro uhoraho ni umwe, ariko voltage ya DC isohoka irahinduka mu rugero runaka bitewe n'ingano y'imbaraga zikoreshwa mu gukwirakwiza umuriro. Uko imbaraga zikoreshwa mu gukwirakwiza umuriro ziba nke, ni ko voltage isohoka iba nke. Uko imbaraga zikoreshwa mu gukwirakwiza umuriro ziba nyinshi, ni ko ingufu zikoreshwa mu gukwirakwiza umuriro ziba nyinshi;

b. Umuyoboro w'amashanyarazi udahinduka ntutinya umuyoboro mugufi w'amashanyarazi, ariko birabujijwe cyane gufungura umuyoboro burundu.

c. Ni byiza ko uruziga rw'amashanyarazi ruhoraho rutwara amatara ya LED, ariko igiciro kiri hejuru ugereranyije.

d. Witondere agaciro ntarengwa k'umuvuduko w'amashanyarazi n'amashanyarazi bikoreshwa, ibyo bikaba bigabanya umubare w'amatara ya LED akoreshwa;

(2) Ubwoko bugenzurwa:

a. Iyo hagaragajwe ibipimo bitandukanye mu muyoboro ugenzura amashanyarazi, amashanyarazi asohoka aba adahinduka, ariko amashanyarazi asohoka arahinduka bitewe n'ubwiyongere cyangwa igabanuka ry'umutwaro;

b. Umuyoboro ugenzura amashanyarazi ntutinya gufungura imizigo, ariko birabujijwe cyane kugabanya umuyoboro burundu.

c. LED itwarwa na circuit ya drive itera imbaraga, kandi buri mugozi ugomba kongerwamo imbaraga zihagije kugira ngo buri mugozi wa LED ugaragaze urumuri rusanzwe;

d. Umucyo uzahinduka bitewe n'impinduka z'amashanyarazi ziturutse ku gukosora.

–Gushyira mu byiciro ingufu za LED:

(3) Inzira yo gukanda umuvuduko w'amaraso (pulse drive)

Porogaramu nyinshi za LED zisaba imikorere yo kugabanya ubukana bw'izuba, nkoAmatara ya LED inyumacyangwa uburyo urumuri rudahinduka mu bwubatsi. Igikorwa cyo kudahinduka gishobora gukorwa hakoreshejwe uburyo bwo guhindura urumuri n'itandukaniro rya LED. Kugabanya gusa ingufu z'amashanyarazi y'igikoresho bishobora gutuma gihinduka.Itara rya LEDGusohora urumuri, ariko kureka LED igakora mu gihe cy’umuvuduko uri hasi ugereranije n’umuvuduko ugenwe bizatera ingaruka nyinshi zitari nziza, nko kunyuranya kw’amashanyarazi. Ubundi buryo bwo guhindura umuvuduko ni ugushyiramo uburyo bwo kugenzura ubugari bwa pulse (PWM) muri driver ya LED. Ikimenyetso cya PWM ntigikoreshwa mu buryo butaziguye mu kugenzura LED, ahubwo gikoreshwa mu kugenzura switch, nka MOSFET, kugira ngo gitange umuvuduko ukenewe kuri LED. Ubusanzwe PWM controller ikora ku murongo udahinduka kandi igahindura ubugari bwa pulse kugira ngo ihuze n’umuvuduko usabwa. Udupira twinshi twa LED dukoresha PWM mu kugenzura urumuri rwa LED. Kugira ngo abantu batazakumva ko umuvuduko ugaragara, umuvuduko wa PWM ugomba kuba urenze 100HZ. Akamaro gakomeye ko kugenzura PWM ni uko umuvuduko unyura muri PWM uba mwiza cyane, ibyo bigatuma itandukaniro ry’amabara rigabanuka iyo LED isohoye urumuri.

(4) Umuyoboro wa AC

Dukurikije porogaramu zitandukanye, disiki za AC zishobora kandi kugabanywamo ubwoko butatu: buck, boost, na converter. Itandukaniro riri hagati ya disiki ya AC na disiki ya DC, uretse kuba ari ngombwa gukosora no kuyungurura AC yinjiye, hari n'ikibazo cyo kwitandukanya no kudatandukanya ukurikije umutekano.

Imashini ikoresha AC ikoreshwa cyane cyane mu matara yo kongera gushyiramo: ku matara icumi ya PAR (Parabolic Aluminium Reflector, itara risanzwe ku rwego rw'umwuga), amatara asanzwe, n'ibindi, akora kuri 100V, 120V cyangwa 230V AC. Ku itara rya MR16, rigomba gukora munsi y'imashini ikoresha AC ya 12V. Bitewe n'ibibazo bimwe na bimwe bigoye, nko ubushobozi bwo kugabanya ubukana bwa triac isanzwe cyangwa leading edge dimmers na trailing edge dimmers, hamwe no guhuza na transformers z'ikoranabuhanga (kuva kuri voltage ya AC kugeza ku gukora 12V AC yo gukoresha itara rya MR16). Ikibazo cy'imikorere (ni ukuvuga, imikorere idahinduka), bityo, ugereranije n'imashini ikoresha DC, urwego rurimo imashini ikoresha AC iragoye cyane.

Ingufu za AC (disiki nkuru) zikoreshwa kuri disiki ya LED, muri rusange binyuze mu ntambwe nko kumanuka, gukosora, kuyungurura, gushimangira voltage (cyangwa gushimangira amashanyarazi), nibindi, kugira ngo bahindure ingufu za AC muri DC, hanyuma batange LED zikwiye binyuze muri disiki ikwiye. Umuriro w'amashanyarazi ugomba kugira ubushobozi bwo guhindura ibintu ku buryo bwo hejuru, ingano nto kandi ihendutse, kandi icyarimwe ugakemura ikibazo cyo kwitandukanya n'umutekano. Ukurikije ingaruka ku miyoboro y'amashanyarazi, ibibazo byo kubangamira amashanyarazi n'ibice by'amashanyarazi nabyo bigomba gukemurwa. Ku ma LED afite ingufu nke n'iziciriritse, imiterere myiza ya disiki ni disiki ihindura ibintu ikoresheje amashanyarazi gusa; ku ngufu nyinshi, hagomba gukoreshwa disiki ihindura ibintu ikoresheje amashanyarazi.

–Ishyirwa mu byiciro ry’aho amashanyarazi ashyirwa:

Ingufu zo gutwara zishobora kugabanywamo ingufu zo hanze n'izubatswemo hakurikijwe aho zishyirwa.

(1) Ingufu zo hanze

Nkuko izina ribigaragaza, ingufu z'amashanyarazi zo hanze zigomba gushyirwaho amashanyarazi hanze. Muri rusange, ingufu z'amashanyarazi ziba nyinshi, ibyo bikaba ari ikibazo ku bantu, kandi ingufu z'amashanyarazi zo hanze zirakenewe. Itandukaniro riri hagati y'amashanyarazi yubatswemo ni uko amashanyarazi afite agace gato, kandi amatara yo ku muhanda ni amwe asanzwe.

(2) Ingufu z'amashanyarazi zubatswemo

Ingufu zishyirwa mu itara. Muri rusange, ingufu z'amashanyarazi ziba nkeya, kuva kuri 12v kugeza kuri 24v, ibyo bikaba bitabangamira umutekano w'abantu. Iri tara risanzwe rifite amatara y'amatara.
