Pakadali pano, paliosapatukanakapangidwe ndikuyendetsa kosiyanamagetsi pamsika wa magetsi a LED.
Kapangidwe kake kosakhala kosiyana kamangokhala ka zinthu zotetezedwa kawiri, monga kuwala kosinthira kwa babu, komwe LED ndi chinthu chonsecho zimaphatikizidwa ndikutsekedwa mu pulasitiki yosayendetsa magetsi, kotero palibe chiopsezo cha kugwedezeka kwa magetsi kwa wogwiritsa ntchito.
Monga momwe zasonyezedwera muchithunzi
Pamene wogwiritsa ntchito ali ndi mwayi wokhudza LED ndi mawaya otulutsa, magetsi oyendetsedwa okha amafunika.
Transformer yodzipatula kapena magetsi a LED drive odzipatula amatanthauza kuti LED ikhoza kukhudzidwa mwachindunji ndi dzanja popanda kugwidwa ndi magetsi. Ngakhale kuti mphamvu ya LED drive yopanda transformer yodzipatula imathabe kutetezera pang'ono makina pogwiritsa ntchito chipolopolo choteteza, LED pakadali pano singathe kulumikizidwa mwachindunji ikugwira ntchito. Magetsi otetezedwa adzakhala otchuka mtsogolomu.
Monga momwe zasonyezedwera pachithunzichi
Mphamvu yamagetsi ya LED yoyendetsedwa ndi mtundu wosiyana ndi mtundu wosiyana ili ndi zabwino ndi zovuta zake, makamaka kuchokera ku mfundo zinayi izi:
Ponena za chitetezo:Mphamvu yodzipatula ili ndi ubwino wambiri, chifukwa mphamvu yodzipatula yokhala ndi magetsi ambiri, magwiridwe antchito ake ndi abwino komanso okhazikika, sizingavulaze thupi la munthu, ndipo ukadaulo wodzipatula umakula kwambiri. Mtundu wosadzipatula, magetsi ndi oipa pang'ono kuposa kudzipatula, magetsi ali pakati pa110V-300Vndi kudzipatulamagetsi angachite60-300V, mphamvu yamagetsi yapamwamba ndi yotsika ndi yofanana kwambiri.
Ponena za magwiridwe antchito:Chitetezo cha kuyendetsa galimoto yamtundu wodzipatula koma magwiridwe antchito otsika, komanso magwiridwe antchito osadzipatula ndi apamwamba.
Ponena za kapangidwe ka dera:Ndondomeko yodzipatula yomwe ilipo panopa nthawi zambiri imakhala ya AC/DC flyback circuit scheme, kotero dera lodziyimira palokha ndi lovuta kwambiri komanso lokwera mtengo. Mtundu wosadzipatula kwenikweni umagwiritsa ntchito DC/DC boost kapena buck circuit, dera lodziyimira palokha ndi losavuta, kotero mtengo wake ndi wotsika.
Ponena za kulondola kwa nthawi zonse kwa magetsi:Mtundu wodzipatula ukhoza kukhala mkati mwa ± 5%. Mtundu wosadzipatula ndi wovuta kuupeza.
Ntchito:
1, mphamvu ya IC kapena gawo la bolodi la dera, kuchokera pa mtengo ndi kuchuluka, kusankha mphamvu yosakhala yodzipatula.
2, kugwiritsa ntchito mphamvu ya batri, pa zosowa za moyo wa batri, kusankha mphamvu ya batri yosadzipatula.
