Vazhinji mainjiniya vanoshanda mukushandura magetsiindustryvarikubatanidzwaLED mutyairi magetsi ekupadesign. Mazhinji makambani ane matatu makuru marudzi emutyairi magetsi ekupa madhizaini:
Chekutanga. Nhanganyaya uye maitiro eLED mutyairi simba
1. Nhanganyaya yeLED mutyairi simba
Simba rekutyaira re LED rinoreva simba rinoshandurwa kuita mwenje we LED kuburikidza nemagetsi ekushandura (senge AC-DC).
Kazhinji kutaura, kupinza ndikohigh-voltage industrial frequency ACkazhinji, inova yatinoti mains magetsi. magetsi emunyika yangu ari 220V/50HZ, uye North America mains magetsi ari 120V/60HZ; chechipiri, varipohigh-voltage uye yakaderera-voltage DC, senge 12V, 24V uye 36V, uye kune zvakare yakaderera-voltage yakakwira-frequency AC, sengeelectronic transformerisu tinoshandisa ichaburitsa inoenderana voltage.
2. Chimiro chazvino uye maitiro eLED mutyairi magetsi ekupa
(1)Kuvimbika kwepamusoro, Kazhinji, waranti yemarambi eNorth America inogona kusvika makore mashanu, izvo zvakanaka.
(2)Kubudirira kwepamusoro, Kushandisakushandura magetsikana mutsara wemagetsi emagetsi, kushanda kwe75 ~ 80% kwakanyanya.
(3)High simba chinhu, kazhinji inosvika pamusoro pe0.9, izvo zvinoreva kuti midziyo inoita basa shoma risina maturo, inoshandisa simba zvakanyanya, uye marambi achagara kwenguva refu.
(4) Iine dziviriro inoshanda senge surge kudzivirira, overvoltage uye undervoltage.
(5) Iine guruva uye basa rekudzivirira mvura, senge IP44 level.
(6) Iyo ine mirairo yekuchengetedza uye electromagnetic kuenderana kuita.
(7) Vatyairi vatatu vakajairika vachakurukurwa pasi apa.
Chepiri. Zvitatu zvakajairikaLED mutyairi magetsi magetsi
1. Kuchinja nguva dzose kwazvino kwazvino
Parizvino, kushandisa akushandura magetsikugadzira LED mutyairi wedunhu ndiyo yakajairika mainstream dhizaini nzira.
Chekutanga pane zvese, kubva kune yayo dhizaini zano, kubva kumagumo ekuisa, kazhinji kuburikidza netransformer yakagadzirwapachayo, iyo yakakwira-voltage maindasitiri frequency AC simba inodzika pasi kune yakaderera voltage (AC-DC), uye yakagadzikana DC voltage inogona kubuda kuburikidza neinogadzirisa sefa reketi. Pamusoro pezvo, iyo EMI sefa yedunhu, kuvhiya uye mheni kudzivirira wedunhu, electrostatic kudzivirira wedunhu, overvoltage uye undervoltage dziviriro wedunhu, nezvimwe zvinowedzerwa, uye kuita kwacho kwacho kwakanyatso uye kuvimbika kwakakwira.
Chechipiri, kune maviri maseketi eiyo switch anogara aripo ikozvino sosi, imwe ndeye yekuzviparadzanisa wedunhu uye imwe yacho isiri yekuzviparadzanisa wedunhu.
Kubva pazita,dunhu rekuzviparadzanisa nevamweyakagadzira mamwe mabhuroko kune mamwe akakwira-voltage kune yakaderera-voltage zvikamu, ine yakakwira chengetedzo kuita, yakakwira yemukati chengetedzo yedunhu, uye zvishoma zvakanyanya kushata kwekunze kwekudzivirira kuita. Icho chinobuda chinodiwa cheNorth America yekuzviparadzanisa wedunhu ndeye <60Vac.
Imwedunhu risiri rogayakaputirwa nekunze insulating plastic shell, iyo isina kuchengetedzeka zvishoma, asi mutengo wakaderera pane wedunhu rekuzviparadzanisa nevamwe. Nzira mbiri idzi dzine zvadzakanakira nezvadzinoipira.
Saka kubva pamapoinzi maviri aya, zvinogona kuoneka kuti magetsi ekuchinja anowanzo kuve nekuchengetedza kurinani kuita uye kuita kwakagadzikana, iyo inofanirwa kuve iyo huru.LED mutyairi magetsi ekupadhizaini zano!
Iyo inonzi mutsara magetsi emagetsi, sekureva kunoita zita, ndeye mutsara magetsi. Kuti zvive chaizvo, iyo yekupinza uye yekubuda voltages zvakangofanana. Semuenzaniso, marambi ekuNorth America anoshandisa mutsara weIC solution, ine 120V/60HZ inobuda uye inobuda inosvika 118V kazhinji.
Zvinogona kuonekwa kuti mutsauko kubva kunekushandura magetsihaisi iyo voltage inoderedzwa ne transformer, asi iyoimwe chete kana yakawanda mutsara ICs inoshandiswa pakuparadzanisa magetsi(zvakajairika ICs dzinosanganisira OB5656). Kune zvakare mashoma mashoma ezvikamu, kunyanya aluminium substrates, pane yakasvibira mhangura-akapfeka mabhodhi eiyo switching magetsi. Imwe pfungwa ndeyokuti ine simba guru uye kushanda kwepamusoro, uye haidi electrolytic capacitors, iyo ine hupenyu hurefu kupfuurakushandura magetsi.
Zvisinei, zvinhu zvose zvine mativi maviri. Kunyange zvazvo ichiita zvakanaka, kubuda kwayo kune high voltage. Kana munhu angoibata, inoisa upenyu panjodzi, saka kazhinji igoko repurasitiki, iro rakachengetedzeka, asi rakaoma kupatsanura.
3. RC kutsika-pasi mhinduro
Iyo inonzi RC kutsika-pasi chaikoinoshandisa iyo yekuchaja uye yekuburitsa hunhu hwe capacitors kune inobuda kutyaira ikozvinokuvhenekera ma LED. Zviri nyore kugadzira, zviri nyore kushandisa, uye zvine mari. Zvisinei, shamwari dzakangwarira dzakaona kuti zviri nyore kukuvadza dunhu nekuda kwekureruka kwayo, uye kune zvakawanda zvisina kugadzikana zvinhu.
Kunyanya muzhizha kana simba risingakwanisi, magetsi akadzimwa uye magetsi achibatidzwa zvakare kazhinji zvinokonzeresa kukuvara kwerambi. Kubuda kwaro kwakafanana neiyo yemutsara IC, uye iyo yakakwira voltage haina kuparadzaniswa, saka ine ngozi kwazvo kushandisa. Nekudaro, goko rayo ipurasitiki, saka kutaura, kuchengetedzeka kwayo hakuna kunaka sekwemagetsi ekuchinja.
Saka iyo general application mamiriro arisimba rakadererarambi, anenge 5W.
Pamibvunzo yechigadzirwa, ndapota tarisa iyochigadzirwa peji, unogamuchirwawotaura nesukuburikidza neruzivo rwekusangana pazasi, isu tichakupindura iwe mukati me24.
