Pakali pano, alipoosadzipatulakupanga ndipaokha galimotomagetsi pamsika wowunikira wa LED.
Mapangidwe osadzipatula okha amangokhala ndi zinthu zomwe zimayikidwa pawiri, monga nyali zolowa m'malo mwa babu, zomwe ma LED ndi zinthu zonse zimaphatikizidwa ndikusindikizidwa mu pulasitiki yopanda ma conductive, kotero palibe chiwopsezo cha kugwedezeka kwa magetsi kwa wogwiritsa ntchito.
Monga zikuwonetsedwa muchithunzi
kumene wosuta ali ndi mwayi kukhudza LED ndi mawaya linanena bungwe, paokha pagalimoto magetsi chofunika.
Transformer yapayokha kapena magetsi amtundu wa LED pagalimoto amatanthawuza kuti LED imatha kukhudzidwa mwachindunji ndi dzanja osagwidwa ndi magetsi. Ngakhale mphamvu yoyendetsa galimoto ya LED popanda kudzipatula thiransifoma ingathebe kukwaniritsa pang'onopang'ono makina otsekemera mothandizidwa ndi chipolopolo choteteza, LED panthawiyi sizingagwirizane nazo pogwira ntchito. Magetsi okhala ndi insulated adzakhala ofala mtsogolomu.
Monga momwe chithunzichi chikusonyezera
Mtundu wosakhala pawokha komanso mtundu wodzipatula wamagetsi amtundu wa LED kuti ukhale ndi zabwino ndi zoyipa zawo, makamaka kuchokera ku mfundo zinayi zotsatirazi:
Pankhani ya chitetezo:kudzipatula magetsi ali ndi ubwino, chifukwa kudzipatula mtundu magetsi ndi voteji lonse, ntchito bwino ndi okhazikika, komanso sangabweretse vuto lililonse kwa thupi la munthu, ndi kudzipatula luso kwambiri okhwima. Osadzipatula mtundu wa voteji ndi woipa pang'ono kuposa kudzipatula, mtundu wa voteji uli pakati110V-300V,ndi kudzipatulamagetsi akhoza kuchita60-300 V, high and low current ndi yunifolomu kwambiri.
Pankhani ya magwiridwe antchito:Kudzipatula kwamtundu wamtundu woyendetsa galimoto koma kutsika bwino, kusadzipatula kwamtundu wagalimoto ndikokwera kwambiri.
Pankhani ya circuit structure:pulogalamu yamakono yodzipatula nthawi zambiri imakhala AC / DC flyback circuit scheme, kotero kuti dera lachibale ndilovuta, lokwera mtengo. Mtundu wosadzipatula umagwiritsa ntchito DC / DC boost kapena buck circuit, dera lachibale ndilosavuta, choncho mtengo wake ndi wotsika.
Ponena za kulondola kwanthawi zonse:mtundu wodzipatula ukhoza kukhala mkati mwa ± 5%. Kusadzipatula ndikovuta kukwaniritsa.
Ntchito:
1, IC kapena gawo la gawo lamagetsi amagetsi, kuchokera pamtengo ndi voliyumu, kusankha kwamagetsi osadzipatula.
2, kugwiritsa ntchito batire mphamvu, pa zofunika moyo batire, kusankha sanali akutali magetsi.
