Parizvino, kuneisina kuparadzaniswadhizaini uyekutyaira kwegamagetsi ari kutengeswa mumusika wemwenje ye LED.
Dhizaini isina kuparadzaniswa inongogumira kuzvigadzirwa zvine insulation mbiri, zvakaita sechiedza chinotsiva girobhu, icho LED nechigadzirwa chose zvakabatanidzwa uye zvakavharwa mupurasitiki isingafambise magetsi, saka hapana njodzi yekuvhundutswa nemagetsi kumushandisi wekupedzisira.
Sezvakaratidzwa mumufananidzo
Kana mushandisi aine mukana wekubata LED netambo dzinobuda, magetsi edhiraivha akapatsanurwa anodiwa.
Transformer yakaparadzana kana magetsi e LED drive akaparadzana zvinoreva kuti LED inogona kubatwa zvakananga neruoko pasina kubatwa nemagetsi. Kunyangwe simba re LED drive risina kuparadzanisa transformer richigona kuwana chikamu chekudzivirira michina nerubatsiro rweganda rekudzivirira, LED panguva ino haigone kubatwa zvakananga kana ichishanda. Mwenje yakadzivirira ichava chinhu chikuru mune ramangwana.
Sezvakaratidzwa mumufananidzo
Simba remagetsi re LED drive risingaparadzanisike uye rine zvakanakira zvaro nezvakaipa, kunyanya kubva pane zvinotevera:
Panyaya yekuchengetedzeka:Simba remagetsi rekupatsanura rine zvakanakira zvakawanda, nekuti simba remagetsi remhando yekupatsanura rine voltage yakafara, mashandiro ari nani uye akagadzikana, harizokonzere kukuvadza muviri wemunhu, uye tekinoroji yekupatsanura iri kukura zvakanyanya. Rudzi rusina kupatsanura, huwandu hwemagetsi hwakaipa zvishoma pane hwekupatsanura, huwandu hwemagetsi huri pakati110V-300Vuye kuzviparadzanisa nevamwemagetsi anogona kuita60-300V, simba remagetsi rakakwirira nerakaderera rakafanana zvikuru.
Panyaya yekushanda zvakanaka:kuchengetedzeka kwekutyaira kwerudzi rwekuzviparadzanisa asi kushanda zvakanaka kushoma, kushanda zvakanaka kwekutyaira kwerudzi rwekuzviparadzanisa kwakakwira.
Panyaya yechimiro chedunhu:Chirongwa chekudzivirira kupatsanurwa kwemagetsi chiripo parizvino chinonyanya kuve chirongwa cheAC/DC flyback circuit, saka dunhu rekudzivirira kupatsanurwa kwemagetsi rakaoma uye rinodhura zvakanyanya. Rudzi rwekusaparadzanisa kupatsanurwa kwemagetsi runonyanya kushandiswa neDC/DC boost kana buck circuit, dunhu rekudzivirira kupatsanurwa kwemagetsi riri nyore, saka mutengo wakaderera.
Panyaya yekururama kwesimba remagetsi nguva dzose:Rudzi rwekuzviparadzanisa runogona kuva mukati me ±5%. Rudzi rwekusazviparadzanisa runonetsa kuwana.
Kushandiswa:
1, IC kana chikamu chemagetsi ebhodhi redunhu, kubva pamutengo uye huwandu, kusarudzwa kwemagetsi asina kuparadzaniswa.
2, kushandiswa kwesimba remagetsi rebhatiri, pane zvinodiwa nehupenyu hwebhatiri, kusarudzwa kwesimba remagetsi risingaparadzaniswe.
