Hariho ubwoko bwinshi bwibicuruzwa bya LED byerekana ibikoresho bya elegitoroniki, ariko ibintu bihuriweho ni uko bagomba gukoresha amashanyarazi ya DC hamwe n’umuvuduko muke w’igikoresho kimwe, kandi umuzenguruko ugomba guhinduka mugihe ukoresheje ingufu zumujyi.Kubikoresha bitandukanye, hariho ibisubizo bitandukanye muburyo bwo gutekinika kwa LED ihindura ingufu.

Ukurikije ingufu z'amashanyarazi, abashoferi ba LED barashobora kugabanywamo ibyiciro bitatu: kimwe gikoreshwa na bateri, cyane cyane gikoreshwa mubikoresho bya elegitoroniki byikurura, gutwara amashanyarazi mato mato mato mato mato mato mato;ikindi ni amashanyarazi arenze 5, akoreshwa nogutanga amashanyarazi ahamye cyangwa bateri Amashanyarazi, nko kumanuka, kumanuka no kumanuka DC ihindura (abahindura; icya gatatu gikoreshwa numuyoboro (110V) cyangwa 220V) cyangwa bihuye na voltage nini itaziguye (nka 40 ~ 400V), ikoreshwa cyane cyane ku ngamiya nini yingamiya Yera LED, nka DC / DC ihinduka.

1. Gahunda yo gutwara amashanyarazi

Amashanyarazi ya batiri muri rusange ni 0.8 ~ 1.65V.Kubikoresho bitanga ingufu nkeya nka LED yerekana, iyi nikibazo gikoreshwa.Ubu buryo burakwiriye cyane cyane kubikoresho bya elegitoroniki byikurura kugirango bitware LED nkeya zifite ingufu nkeya kandi ziciriritse, nk'amatara ya LED, amatara yihutirwa ya LED, amatara yo kuzigama ingufu, n'ibindi. Urebye ko bishoboka gukorana na bateri ya AA na gira ingano ntoya, igisubizo cyiza cya tekiniki nigisubizo cya pompe yongerera imbaraga, nko kuzamura DC Zhuang (guhinduranya cyangwa kuzamura (cyangwa Bake mubahindura pompe yishyurwa ryubwoko bwa buck-boost ni abashoferi bakoresha imirongo ya LDO.

2. Umuvuduko mwinshi hamwe na gahunda yo gutwara

Gahunda yo gutanga amashanyarazi make hamwe na voltage irenze 5 ikoresha amashanyarazi yabugenewe cyangwa bateri kugirango itange amashanyarazi.Umuvuduko wa voltage yumuriro wa LED uhora uri hejuru kurenza LED ya voltage yamanuka, ni ukuvuga ko ihora irenze 5V, nka 6V, 9V, 12V, 24V cyangwa irenga.Muri iki gihe, ikoreshwa cyane cyane nu mashanyarazi ahamye cyangwa bateri yo gutwara amatara ya LED.Ubu bwoko bwo gutanga amashanyarazi bugomba gukemura ikibazo cyo gutanga amashanyarazi hasi-hasi.Ubusanzwe porogaramu zirimo amatara yizuba, amatara yizuba, hamwe na sisitemu yo gucana ibinyabiziga.

3. Gahunda yo gutwara ibinyabiziga ikoreshwa na moteri cyangwa amashanyarazi menshi

Iki gisubizo gikoreshwa nuburyo butaziguye (100V cyangwa 220V) cyangwa umuyaga uhuza umuyaga mwinshi, kandi ukoreshwa cyane cyane mugutwara amatara maremare ya LED yera.Mains Drive nuburyo bwo gutanga amashanyarazi hamwe nigiciro kinini cyo kugereranya LED yerekana, kandi nicyerekezo cyiterambere cyo kumenyekanisha no gukoresha amatara ya LED.

Iyo ukoresheje imbaraga zingenzi kugirango utware LED, birakenewe gukemura ikibazo cyo kugabanya ingufu za voltage no gukosorwa, ariko kandi no kugira imikorere ihindagurika cyane, ingano ntoya nigiciro gito.Byongeye kandi, ikibazo cyo kwigunga cyumutekano kigomba gukemuka.Urebye ingaruka kuri gride yamashanyarazi, kwivanga kwa electromagnetic hamwe nibibazo byingufu nabyo bigomba gukemurwa.Kumashanyarazi aciriritse kandi make LEDs, imiterere yumuzunguruko mwiza ni imwe yonyine igarukira kuguruka.Kubikorwa-byimbaraga nyinshi, imirongo yo guhindura ikiraro igomba gukoreshwa.

Ku gutwara LED, ikibazo nyamukuru ni ukutagira umurongo wa LED yerekana.Ibi bigaragarira cyane cyane ko imbere yimbere ya voltage ya LED izahinduka hamwe nubushyuhe, ubushyuhe bwimbere bwibikoresho bitandukanye bya LED bizaba bitandukanye, "ibara ryibara" rya LED rizagenda hamwe nubushyuhe, hamwe nubushyuhe, hamwe LED igomba kuba mubisabwa ibisobanuro.Kora murwego kugirango ugere kubikorwa byizewe.Igikorwa nyamukuru cyumushoferi wa LED nuguhagarika ikigezweho mubihe byakazi, utitaye kumihindagurikire yimiterere yinjiza na voltage yimbere.

Kumashanyarazi ya LED, usibye guhora uhagaze neza, hari nibindi byingenzi bisabwa.Kurugero, niba ukeneye gukora LED dimming, ugomba gutanga tekinoroji ya PWM, kandi mubisanzwe PWM inshuro ya LED dimming ni 1 ~ 3kHz.Mubyongeyeho, ubushobozi bwo gukoresha ingufu za LED ya moteri igomba kuba ihagije, ikomeye, ibasha kwihanganira ibintu bitandukanye byamakosa, kandi byoroshye kubishyira mubikorwa.Birakwiye kuvuga ko kuberako LED ihora kumurongo mwiza kandi ntuzagenda.

Muguhitamo LED yerekana ibishushanyo mbonera, inductance izamura DC / DC yatekerejwe kera.Mu myaka yashize, ikigezweho ko umushoferi wa pompe yishyurwa ashobora gusohoka yavuye kuri mA magana agera kuri 1.2A.Kubwibyo, ibi bibiri Ibisohoka byubwoko bwa actuator birasa.
