Inofanira -ona: LED Driver Power Knowledge Knowledge

Kupisa kupisa, simba rekutyaira, uye mwenje masosi ndiwo akanyanya kukosha zvikamu zveakanaka mwenje chigadzirwa che LED. Kunyange zvazvo kupisa kwekushisa kunonyanya kukosha, kupisa kwekushisa kunobata zvakananga hupenyu hwezvigadzirwa zvemwenje, asi chiedza chechiedza ndicho chikamu chikuru chechigadzirwa chose. Kugadzikana kwehupenyu uye kubuda ikozvino uye voltage yemagetsi pachayo ine simba guru pahupenyu hwese hwechigadzirwa. Iyo LED mutyairi magetsi inopa zvakare chigadzirwa chinotsigira. Parizvino, hutano hwemagetsi pamusika hauna kuenzana. Izvi zvinotevera zvinopa humwe ruzivo rwakabatana rwe LED mutyairi simba. 1. Chii chinonzi LED drive power supply LED drive power supply inoshandura magetsi kune chaiyo voltage ikozvino kutyaira LED light -emitting voltage converter. Kazhinji: iyo inopinza ye LED drive simba inosanganisira yakakwira -voltage frequency AC (kureva, simba reguta), low voltage DC DC , High -voltage DC, yakaderera -voltage uye yakakwirira -frequency AC (sekubuda kwemagetsi emagetsi), etc. Kubuda kweiyo LED dhiraivha magetsi kazhinji ndiyo inogara iripo sosi inogona kushandura voltage neshanduko mukudzikisira kukosha kweiyo LED kumberi voltage. Izvo zvakakosha zvemagetsi emagetsi eLED zvinosanganisira switch controller, induction, switch component (MOSFET), mhinduro kuramba, yekuisa sefa mudziyo, inobuda sefa mudziyo, nezvimwe. Zvinoenderana nezvinodiwa zvezviitiko zvakasiyana, panofanirwa kuve nekupinza overvoltage edziviriro maseketi, yekuisa -kushaya kudzvanywa kwedziviriro maseketi, LED kuvhura nzira dziviriro, overcurrent kudzivirira uye mamwe maseketi. 2. Zvimiro zve LED drive magetsi ekupa (1) Kuvimbika kwakanyanya kunonyanya kufanana nemagetsi emutyairi emagetsi emumugwagwa e LED, anoiswa pakakwirira, haakodzeri kugadzirisa, uye mutengo wekugadzirisa zvakare wakakura. (2) High-efficiency LED chigadzirwa chekuchengetedza simba, uye kushanda kwesimba rekutyaira kwakakwirira. Izvo zvakakosha zvakanyanya pakupisa kwekupisa kwesimba remagetsi mumwenje. Kubudirira kwesimba rekupa simba kwakakwirira, kurasikirwa kwayo kwehuremu kuduku, uye kupisa mumwenje kuchava kuduku, izvo zvichaderedza kutonhora kwekukwira kwemwenje. Izvo zvinobatsira kunonoka kutadza kwechiedza che LED. (3) High-simba zvinhu uye simba zvinhu zvinodikanwa zvekuremerwa kwegridi yegridi. Kazhinji, midziyo yemagetsi iri pasi pe70 watts, hapana zviratidzo zvinosungirwa. Kunyange zvazvo simba rimwechete rine simba rakaderera, simba rakaderera rine simba shoma pane girasi remagetsi, kushandiswa kwekuvhenekera usiku, rudzi rwakafanana rwemutoro wakanyanyisa, huchakonzera kusvibiswa kwakakomba kune girasi remagetsi. Kune iyo LED mutyairi simba re30 watts 40 watts, zvinonzi munguva pfupi iri kutevera, panogona kunge paine zvimwe zviratidzo zvesimba zvinhu. (4) Kune marudzi maviri enzira dzekutyaira izvozvi: imwe inogara iri voltage sosi kune akawanda anogara achiyerera masosi, uye imwe neimwe inogara iripo sosi inopa kune yega yega LED zvakasiyana. Nenzira iyi, kusanganiswa kunoshanduka, kukundikana kwe LED nzira yose, haikanganisi basa remamwe ma LED, asi mari ichave yakakwirira zvishoma. Imwe yacho inogara yakananga ikozvino magetsi ekupa, iyo zvakare “Zhongke Huibao “Iyo nzira yekutyaira yakagamuchirwa, iyo LED yakabatana kana yakafanana. Zvakanakira kuti mutengo wakaderera, asi kuchinjika kwakashata, uye zvinodikanwa kugadzirisa dambudziko reimwe LED kukundikana, iyo isingakanganisi kushanda kwemamwe ma LED mashandiro. Aya mafomu maviri anogara kwenguva yakati. Multi -Lu Hengliu inobuda magetsi ekupa nzira dzichava nani maererano nemutengo uye kuita. Pamwe ndiyo nzira huru mune ramangwana. (5) Kugona kuchengetedza kuchengetedzwa kwe LED kwe LED kune hurombo, kunyanya iyo anti-reverse voltage simba. Kusimbisa kudzivirira munzvimbo iyi kunokosha zvakare. Mamwe marambi e LED anoiswa kunze, akadai semwenje ye LED mumugwagwa. Nekuda kwekuvhurwa kwegedhi remagetsi mutoro uye kuiswa kwemheni inorova, iyo grid system ichapinda mafungu akasiyana-siyana, uye mamwe masaisai anokonzeresa kukuvara kwe LED. Naizvozvo kuongorora “Zhongke Huibao “Simba remutyairi rinofanira kunge risina kuchengetedzwa kwemafungu emhepo. Kana zviri zvekudzoreredzwa kwesimba uye marambi, iyo LED drive magetsi inofanirwa kuve nekugona kudzvanya kuvhiya uye kuchengetedza kugona kwe LED kuti irege kukuvara. (6) Pamusoro peyakajairwa kuchengetedza basa, iro rekudzivirira basa simba rakanakisa kuwedzera LED tembiricha isina kunaka mhinduro kune inogara iripo inobuda kudzivirira tembiricha ye LED kuti isanyanya kukwirira;. 3. Kurongeka zvinoenderana nenzira yekutyaira (1) Ikozvino kubuda kweiyo inogara iripo ikozvino dhiraivha yedunhu inogara, nepo inobuda DC voltage inochinja mukati meimwe chiyero nehukuru hwekuremerwa kwemutoro, kukosha kwekuremerwa idiki, kubuda. voltage is Kana iri yakaderera, iyo yakakura kukosha kwekuremerwa kwemutoro, iyo yakakwira inobuda voltage; iyo inogara iripo yedunhu haityi mutoro kupfupi wedunhu, asi mutoro unorambidzwa zvachose; iyo Hengliu yekutyaira yedunhu yakanyanya kunaka, asi mutengo wakanyanya kukwirira; zviteerere; teerera Iyo yakanyanya kushivirira uye kukosha kwevoltage inoshandiswa, inomisa huwandu hwema LED. (2) Mushure mekunge maparamita akasiyana-siyana ari museti yekudzikamisa akatemerwa, iyo inobuda voltage inogadziriswa, uye inobuda ikozvino inoshanduka nekuwedzera uye kuderera kwemutoro; Short circuit; dhiraivha iyo LED kutyaira iyo voltage -driven circuit, tambo imwe neimwe inoda kuwedzera kupikisa kwakakodzera kuita tambo yega yega ye LED kuratidza avhareji kupenya; kupenya kuchakanganiswa nekuchinja kwemagetsi kubva pakugadzirisa. 4. Zvakanakira nekuipira kweiyo yakazara inogara iripo uye nzira yekutevera nzira inofananidzwa neyakazara inogara iripo. Kunyange zvazvo kune zvakawanda zvisingabatsiri uye kudhura kwakanyanya, mutengo wacho wakakura. Asi inogona kuchengetedza zvechokwadi hupenyu hwe LED uye kuwedzera iyo LED, saka iyo inogara ichiyerera yemugwagwa ndiyo ramangwana maitiro. 5. Kushaikwa kweiyo LED magetsi emagetsi LED -inotyairwa magetsi ekupa parizvino haina kukwana: 1. Iwo matekinoroji emakambani anogadzira mwenje we LED uye zvigadzirwa zvine hukama havazive zvakakwana nezve switching magetsi. Uye kwete kufunga electromagnetic kuenderana zvakakwana, pachine dzimwe njodzi dzakavanzika; 2. Mazhinji emagetsi emagetsi emagetsi emagetsi emagetsi anoshandurwa kubva kune akajairwa ekuchinja magetsi ekugadzira magetsi e LED. Hunhu uye kunzwisisa kwe LED hazvina kukwana; Iko kune anenge asina zviyero, mazhinji ayo ari chiyero chekutaura kune switch yemagetsi magetsi uye yemagetsi rectifier; mazhinji emagetsi e LED haana yunifomu, saka mazhinji emari yacho idiki. Kana vhoriyamu yekutenga iri diki, mutengo wakakwira, uye mupi wechikamu haadyidzane zvakanyanya; 4. Kugadzikana kweiyo LED magetsi emagetsi: iyo yakafara voltage kupinza, yakanyanya tembiricha uye yakaderera tembiricha basa, pamusoro tembiricha, overvoltage kudzivirira uye zvimwe zvinhu hazvina kuzvigadzirisa imwe neimwe. Yokutanga ndiyo hupenyu hwese hwekufambisa kwekufambisa, kunyanya zvigadziri zvakakosha zvakadai se: hupenyu hwe capacitors pakupisa kwepamusoro hunobata zvakananga hupenyu hwemagetsi; kuti LED drive inofanira kupikisa yakakwirira kutendeuka kushanda zvakanaka, kunyanya kana uchityaira ma-LEDs e-high-power, nokuti nokuti inotungamirirwa ne-high-power LED, nokuti inotungamirirwa ne-high-power LED, nokuti nokuti mutyairi we-high-power LED imhaka yekuti. yemutyairi we-high-power LED, nokuti nokuti ndiye mutyairi we-high-power LED, nokuti nokuti ndiye mutyairi we-high-power LED, nokuti nokuti ndiye mutyairi we-high-power LED, nokuti nokuti ndiye mutyairi wepamusoro-simba. LED, nokuti nokuti ndiyo mutyairi we-high-power LED, nokuti nokuti ndiyo mutyairi we-high-power LED, nokuti nokuti ndiyo mutyairi we-high-power LED, nokuti nokuti ndiyo mutyairi we-high-power LED, nokuti nekuti mutyairi wepamusoro-simba LED imhaka yekuti inotonyanya chokwadi, nekuti yakatonyanya kudaro. Simba rose risiri kunze kwechiedza rinoshandiswa sekupisa kupisa, uye simba rekushandura simba rakanyanya kuderera, izvo zvinokanganisa kushanda kwe LED simba -saving effects. Parizvino, mumashandisirwo ane simba diki (1-5W), chikamu chemutengo weHengliu kutyaira magetsi chave pedyo ne1/3, iri padyo nemutengo wezviedza zvemwenje, izvo zvinokanganisa kukwidziridzwa kwemusika kune imwe nhanho. .
