Mphamvu yamagetsi ya LED ndi chosinthira mphamvu chomwe chimasintha magetsi kukhala magetsi enaake komanso apano kuti ayendetse ma LED kuti atulutse kuwala.Nthawi zonse: kuyika kwa magetsi a LED kumaphatikizapo ma frequency amphamvu amagetsi a AC (mwachitsanzo, mphamvu ya mzinda), low-voltage DC, high-voltage DC, low-voltage ndi high-voltage.Frequency AC (monga kutulutsa kwa thiransifoma yamagetsi), etc.

-Kutengera njira yoyendetsera:

(1) Mtundu wanthawi zonse

a.Zomwe zimatuluka pamayendedwe apano oyendetsa nthawi zonse zimakhala zokhazikika, koma ma voliyumu a DC amasiyana pakati pamitundu ina ndi kukula kwa kukana katundu.Zing'onozing'ono kukana katundu, m'munsi linanena bungwe voteji.Kuchuluka kwa kukana katundu, kutulutsa Kukwera kwamagetsi;

b.Kuzungulira komweko nthawi zonse sikumawopa katundu wocheperako, koma ndikoletsedwa kuti mutsegule katunduyo kwathunthu.

c.Ndikoyenera kuti pakhale mayendedwe apakali pano kuyendetsa ma LED, koma mtengo wake ndi wokwera.

d.Samalani kupirira kwakukulu komwe kumagwiritsidwa ntchito pakalipano ndi magetsi, zomwe zimachepetsa kuchuluka kwa ma LED omwe amagwiritsidwa ntchito;

(2) Mtundu woyendetsedwa:

a.Pamene magawo osiyanasiyana amagetsi oyendetsa magetsi atsimikiziridwa, mphamvu yotulutsa mphamvu imakhazikika, koma zomwe zikuchitika panopa zikusintha ndi kuwonjezeka kapena kuchepa kwa katundu;

b.Voltage regulator dera sawopa kutsegula kwa katundu, koma ndikoletsedwa kufupikitsa katunduyo kwathunthu.

c.Kuwala kwa LED kumayendetsedwa ndi dera loyendetsa magetsi, ndipo chingwe chilichonse chiyenera kuwonjezeredwa ndi kukana koyenera kuti chingwe chilichonse cha LED chiwonetse kuwala kwapakati;

d.Kuwalako kudzakhudzidwa ndi kusintha kwa magetsi kuchokera kukonzanso.

-Kugawika kwa magetsi a LED:

(3) Kuthamanga kwamphamvu

Mapulogalamu ambiri a LED amafunikira ntchito za dimming, mongaKuwala kwa LEDkapena dimming ya zomangamanga.Ntchito ya dimming imatha kuzindikirika posintha kuwala ndi kusiyana kwa LED.Mwachidule kuchepetsa panopa chipangizo angathe kusinthaKuwala kwa LEDkutulutsa, koma kulola ma LED kuti agwire ntchito pansi pazikhalidwe zotsika kuposa zomwe zidavotera kungayambitse zotsatira zoyipa zambiri, monga kusintha kwa chromatic.Njira ina yosinthira pakali pano ndikuphatikiza chowongolera cha pulse wide modulation (PWM) mu driver wa LED.Chizindikiro cha PWM sichimagwiritsidwa ntchito mwachindunji kuwongolera LED, koma kuwongolera chosinthira, monga MOSFET, kuti apereke zomwe zikufunika pakalipano ku LED.Wolamulira wa PWM nthawi zambiri amagwira ntchito pafupipafupi ndipo amasintha makulidwe ake kuti agwirizane ndi ntchito yofunikira.Tchipisi zambiri zamakono za LED zimagwiritsa ntchito PWM kuwongolera kutulutsa kwa kuwala kwa LED.Pofuna kuwonetsetsa kuti anthu sangamve ngati akuthwanima, kuchuluka kwa kugunda kwa PWM kuyenera kukhala kwakukulu kuposa 100HZ.Ubwino waukulu wa kuwongolera kwa PWM ndikuti dimming current kudzera pa PWM ndiyolondola, zomwe zimachepetsa kusiyana kwa mtundu pomwe LED imatulutsa kuwala.

(4) AC pagalimoto

Malinga ndi mapulogalamu osiyanasiyana, ma drive a AC amathanso kugawidwa m'mitundu itatu: buck, boost, and converter.Kusiyanitsa pakati pa AC pagalimoto ndi DC pagalimoto, kuwonjezera pa kufunikira kokonza ndi kusefa zolowetsa za AC, palinso vuto la kudzipatula komanso kusadzipatula kuchokera kumalo otetezedwa.

Dalaivala yolowera ya AC imagwiritsidwa ntchito makamaka pakuwunikira nyali: kwa khumi PAR (Parabolic Aluminiyamu Reflector, nyali wamba pa siteji ya akatswiri) nyali, mababu wamba, ndi zina zotero, zimagwira ntchito pa 100V, 120V kapena 230V AC Kwa nyali ya MR16, ikufunika kugwira ntchito pansi pa 12V AC zolowetsa.Chifukwa cha zovuta zina, monga kuchepa kwa ma triac wamba kapena nsonga zotsogola ndi ma dimmers am'mphepete, komanso kuyanjana ndi ma transfoma amagetsi (kuchokera ku AC line voltage kuti apange 12V AC pakugwiritsa ntchito nyali ya MR16) Vuto la magwiridwe antchito (ndiko, kufinya -ntchito yaulere), chifukwa chake, poyerekeza ndi dalaivala wolowetsa wa DC, gawo lomwe likukhudzidwa ndi dalaivala wa AC ndizovuta kwambiri.

Magetsi a AC (ma mains drive) amagwiritsidwa ntchito pagalimoto ya LED, nthawi zambiri kudzera pamasitepe monga kutsika, kukonzanso, kusefa, kukhazikika kwamagetsi (kapena kukhazikika kwapano), ndi zina zambiri, kutembenuza mphamvu ya AC kukhala mphamvu ya DC, kenako ndikupereka ma LED oyenera. kupyolera mu kayendedwe ka galimoto yoyenera Kugwira ntchito kwamakono kumayenera kukhala ndi kutembenuka kwakukulu, kukula kochepa ndi mtengo wotsika, ndipo nthawi yomweyo kuthetsa vuto la kudzipatula kwa chitetezo.Poganizira za kukhudzidwa kwa gridi yamagetsi, kusokoneza ma electromagnetic ndi zovuta zamagetsi ziyeneranso kuthetsedwa.Kwa ma LED otsika ndi apakatikati amphamvu, mawonekedwe abwino kwambiri ozungulira ndi gawo lakutali laling'ono lakumbuyo lakumbuyo;pakugwiritsa ntchito mphamvu zambiri, chosinthira mlatho chiyenera kugwiritsidwa ntchito.

-Magawo oyika mphamvu zamagetsi:

Mphamvu yoyendetsa imatha kugawidwa kukhala magetsi akunja ndi magetsi omangidwa molingana ndi malo oyika.

(1) Magetsi akunja

Monga momwe dzinalo likusonyezera, magetsi akunja ndikuyika magetsi kunja.Nthawi zambiri, magetsi amakhala okwera kwambiri, zomwe ndi zowopsa kwa anthu, ndipo magetsi akunja amafunikira.Kusiyanitsa ndi magetsi opangidwa mkati ndikuti magetsi ali ndi chipolopolo, ndipo magetsi a mumsewu ndi ofala.

(2) Magetsi omangidwa

Mphamvu yamagetsi imayikidwa mu nyali.Nthawi zambiri, magetsi ndi otsika, kuchokera ku 12v mpaka 24v, zomwe sizimayika ngozi kwa anthu.Chofala ichi chimakhala ndi magetsi a babu.
