Hariho ubwoko bwinshi bwa LED itanga amashanyarazi.Ubwiza nigiciro cyibikoresho bitandukanye bitanga ingufu biratandukanye cyane.Iki kandi nikimwe mubintu byingenzi bigira ingaruka kumiterere yibicuruzwa nigiciro.Amashanyarazi ya LED arashobora kugabanywamo ibyiciro bitatu, guhinduranya amasoko ahoraho, gutanga amashanyarazi kumurongo wa IC, hamwe no guhangana-capacitance kumanuka kumashanyarazi.
1. Guhindura ibintu bihoraho isoko ikoresha transformateur kugirango ihindure voltage ndende kuri voltage ntoya, kandi ikora ubugororangingo no kuyungurura kugirango isohokane imbaraga zidasanzwe zidasanzwe.Guhindura buri gihe isoko igabanijwemo amashanyarazi yihariye hamwe no gutanga amashanyarazi adahari.Kwigunga bivuga kwigunga bisohoka hejuru na voltage ntoya, kandi umutekano ni mwinshi cyane, bityo rero ibisabwa kugirango insulire yikigero ntabwo iri hejuru.Umutekano udatandukanijwe ni mubi gato, ariko ikiguzi ni gito.Amatara gakondo azigama ingufu akoresha amashanyarazi adashyizwe hamwe kandi akoresha igikonoshwa cya plastike gikingiwe kurinda.Umutekano wo guhinduranya amashanyarazi ni mwinshi (muri rusange ibisohoka ni voltage nkeya), kandi imikorere irahagaze.Ikibi nuko umuziki utoroshye kandi igiciro kiri hejuru.Amashanyarazi ahinduranya afite tekinoroji ikuze kandi ikora neza, kandi kuri ubu ni isoko nyamukuru itanga amashanyarazi ya LED.
2. Imirongo itanga amashanyarazi ikoresha IC imwe cyangwa IC nyinshi kugirango ikwirakwize voltage.Hano hari ubwoko buke bwibikoresho bya elegitoronike, ibintu bitanga ingufu nubushobozi bwo gutanga amashanyarazi biri hejuru cyane, nta capacitori ya electrolytike ikenewe, kuramba no kugiciro gito.Ikibi ni uko ibisohoka n’umuvuduko mwinshi bidasohoka, kandi hariho stroboscopique, kandi uruzitiro rusabwa kurindwa inkuba.Bose bakoresha umurongo w'amashanyarazi ya IC ku isoko bavuga ko nta capacitori ya electrolytike n'ubuzima burebure.Amashanyarazi ya IC afite ubwizerwe buhanitse, gukora neza hamwe ninyungu zihenze, kandi nibyiza LED itanga amashanyarazi mugihe kizaza.
3. Amashanyarazi ya RC yamanutse akoresha capacitor kugirango itange amashanyarazi binyuze mumashanyarazi no gusohora.Umuzunguruko uroroshye, ikiguzi ni gito, ariko imikorere irakennye, kandi ituze ni mibi.Biroroshye cyane gutwika LED mugihe gride ya voltage ihindagurika, kandi ibisohoka ni voltage nini cyane.Gukingira igikonoshwa.Imbaraga nke nubuzima bugufi, mubisanzwe bikwiranye nubukungu buke buke (muri 5W).Kubicuruzwa bifite imbaraga nyinshi, ibisohoka ni binini, kandi capacitor ntishobora gutanga amashanyarazi manini, naho ubundi biroroshye gutwika.Byongeye kandi, igihugu gifite ibisabwa kugirango habeho ingufu z'amatara maremare, ni ukuvuga ko ingufu ziri hejuru ya 7W zisabwa kuba zirenga 0.7, ariko amashanyarazi-ubushobozi-buke-buke-buke ntibugera kure (mubisanzwe hagati 0.2-0.3), bityo ibicuruzwa bifite ingufu nyinshi ntibigomba gukoreshwa RC kumanuka kumashanyarazi.Ku isoko, ibicuruzwa hafi ya byose byo mu rwego rwo hasi bifite ibisabwa bike bifashisha amashanyarazi ya RC yamanutse, kandi ibicuruzwa bimwe na bimwe byo hasi, bifite ingufu nyinshi nabyo bikoresha amashanyarazi ya RC yamanutse.
