Mikanda ya Nyali ya LED Imagwiritsidwa Ntchito Nthawi zambiri Njira Zolumikizirana

Kusintha kwa mawonekedwe a LED mukugwiritsa ntchito kumadalira zinthu zambiri, kuphatikiza magawo a LED ndi kuchuluka kwake, magetsi olowera, mphamvu, kasamalidwe ka kutentha kwapang'onopang'ono, kukula ndi kuletsa masanjidwe ndi ma optics, ndi zina zambiri. Fomu yosavuta yosinthira ndi LED imodzi. Chifukwa ndege nthawi zambiri zimafunikira pazochitika zenizeni zogwiritsira ntchito, ma LED angapo amafunika kukonzedwa ndikuphatikizidwa ngati pakufunika kuti akwaniritse zofunikira zogwiritsira ntchito zazikulu, zowala kwambiri, maonekedwe amphamvu, kusintha kwa mitundu, ndi zofunikira zofanana za LED ndi madalaivala othandizira. I. Patsa zapadzi edz1. Mawonekedwe osavuta amtunduwu nthawi zambiri amalumikizidwa mu LED1 LEDN m'njira yosavuta yolumikizirana, ndipo yomwe ikuyenda nthawi ya LED ndi yofanana. Kwa ma LED omwe ali ndi zizindikiro zofanana ndi magulu, ngakhale magetsi pa LED imodzi akhoza kukhala ndi kusiyana pang'ono, chifukwa LED ndi chipangizo chamakono, ikhoza kutsimikizira kuti kuwala kwawo kowala kumakhala kofanana. Chifukwa chake, mndandanda wosavuta wa ma LED uli ndi mawonekedwe a mabwalo osavuta komanso kulumikizana kosavuta ndi mawonekedwe ena. (Zoipa: Chifukwa cha kugwiritsa ntchito mndandanda, pamene imodzi ya LED ikulephera, magetsi onse a LED adzazimitsidwa, zomwe zidzakhudza kudalirika kwa ntchito. ) 2. Mitundu yotsatizana ya ma diode awiri ophatikizika a Qina diode amalumikizidwa ndi mawonekedwe olumikizidwa bwino a Qina diode molumikizana. Mu njira yolumikizira iyi, voteji yakuwonongeka kwa diode iliyonse ya Zina ndi yayikulu kuposa voteji yogwira ntchito ya LED. Pamene ntchito bwinobwino, chifukwa Qina diode VD1 VDN si galimoto, panopa makamaka umayenda mwa LED1 LEDN. Pamene LED yowonongeka mu chingwe cha LED imayambitsidwa Kuwonjezera pa LED, ma LED ena akadali ndi mafunde omwe amadutsa ndi kuwala. WeChat pagulu nkhani: Shenzhen LED Chamber of Commerce (njira yolumikizira iyi ndi mawonekedwe osavuta angapo asintha kwambiri kudalirika pankhani yodalirika. ) Chachiwiri, mawonekedwe onse ofanana 1. Mawonekedwe osavuta ofananira, osavuta komanso olumikizidwa a LED1 mchira wa mutu wa LED1, LED iliyonse ndi yofanana ndi voteji yofanana, voteji yofanana. Itha kuwoneka kuchokera ku mawonekedwe a LED. Ndi ya chipangizo chamakono, ndipo kusintha pang'ono kwa magetsi owonjezeredwa ku LED kumayambitsa kusintha kwakukulu pakali pano. Kuphatikiza apo, chifukwa cha zofooka zaukadaulo wopanga ma LED, ngakhale gulu lomwelo la ma LED, pali kusiyana kwa magwiridwe antchito. Choncho, pamene LED1 LEDN ntchito, panopa ikuyenda mwa aliyense LED si wofanana. Zitha kuwoneka kuti kugawa kosagwirizana kwa ma LED onse pakalipano kungapangitse kuti moyo wa LED wapano ukhale wokulirapo, komanso kupsa. (Zoipa: Ngakhale njira yolumikizira iyi ndi yosavuta, koma kudalirika sikwapamwamba, makamaka pazogwiritsa ntchito ma LED ambiri. ) 2. Mtundu wofananira wofananira wodziyimira umalimbana ndi kudalirika kwa kufanana kosavuta. Fomu yofananira yodziyimira payokha ndi njira yabwino. LED iliyonse mwanjira imeneyi imakhala ndi chosinthika chamakono (drive Voutput terminal ndi L1 Ln) kuti iwonetsetse kuti yomwe ikuyenda kudzera pa LED iliyonse ili mkati mwazofunikira zake, ndi zotsatira zabwino zoyendetsa, chitetezo chimodzi cha LED Chokwanira, sichikhudza ma LED ena. gwirani ntchito pakalakwitsa, ndipo imatha kufanana ndi mawonekedwe a ma LED okhala ndi kusiyana kwakukulu. (Zoyipa: Kapangidwe kagawo lonse la driver ndizovuta, mtengo wa chipangizocho ndi wokwera, voliyumu imakhala yochulukirapo, siyoyenera kuchuluka kwa mabwalo a LED. ) Chachitatu, mawonekedwe osakanikirana amapangidwe osakanikirana amaperekedwa mwa kuphatikiza ubwino wa mndandanda ndi mawonekedwe ofanana. Mafomu akuluakulu ndi awiri otsatirawa. 1. Pamene mawonekedwe osakanikirana apangidwe ali oyamba, pamene chiwerengero cha ntchito za LED ndi zazikulu, mndandanda wosavuta kapena kugwirizana kofananira sikungatheke, chifukwa choyambiriracho chimafuna kuti dalaivala atulutse magetsi apamwamba (N nthawi za VF imodzi ya LED voteji), ndipo chotsiriziracho. imafuna dalaivala kuti afune dalaivala Kutulutsa mphamvu yayikulu (N nthawi za LED imodzi yokha ngati). Izi zimabweretsa zovuta pakupanga ndi kupanga dalaivala, komanso kumaphatikizanso zovuta zamapangidwe komanso magwiridwe antchito onse agalimoto. Magetsi a kuchuluka kwa ma LED otsatizana ndi voteji yogwira ntchito ya VF imodzi ya LED imatsimikizira mphamvu yotuluka pa chipangizo choyendetsa; Mtengo umatsimikizira mphamvu yotulutsa dalaivala. Choncho, kusakaniza njira pambuyo kusakaniza makamaka kuonetsetsa kuti pali kudalirika (kulakwitsa kwa LED mu chingwe chilichonse kumangokhudza kuwala kwabwino kwa chingwe), ndi kufanana kwa kayendedwe ka galimoto ), Kumapangitsa kudalirika kusiyana ndi mitundu yosavuta . WeChat public account: Shenzhen LED Chamber of Commerce (dera lonselo lili ndi mawonekedwe a mawonekedwe osavuta, kulumikizana kosavuta, kuchita bwino kwambiri, etc., koyenera kugwiritsa ntchito ma LED ambiri. ) 2. Ma LED angapo omwe amasakanizidwa ndi chingwe choyamba, ndi mitundu yosakanikirana yolumikizirana pamaso pa chingwe. Popeza LED1-N LEDM-N imayamba kulumikizidwa kuti igwirizane, zomwe zimapangitsa kudalirika kwa gulu lililonse la ma LED, koma izi ndizofunikira. Pazifukwa izi, mutha kusankha voteji yogwira ntchito komanso yapano momwe mungathere ngati gulu lofananira pophatikiza, kapena kuthetsa kukana kwakung'ono kwa LED iliyonse. (Makhalidwe ena a mawonekedwe osakanikirana awa ndi zovuta zomwe zilipo ndizofanana. ) Chachinayi, mitundu yopingasa yamitundu yosiyanasiyana ndiyomwe imathandizira kudalirika kwa ntchito ya LED ndikuchepetsa kulephera. Njira yayikulu yopangira ndi: mndandanda uliwonse wa ma LED atatu monga gulu, ndi VA, VB, ndi VC zotulutsa zomwe zimalumikizidwa ndi kutulutsa kwagalimoto. Pamene ma LED a 3 a mndandanda ali abwinobwino, ma LED a 3 akuwala nthawi imodzi; kamodzi kapena awiri ma LED ndi osavomerezeka, akhoza kuonetsetsa kuti osachepera limodzi LED ntchito bwinobwino. Mwanjira iyi, imatha kusintha kwambiri kudalirika kwa gulu lililonse la kuwala kwa LD, ndipo imatha kuwongolera kudalirika konse kwa kuwala konse kwa LED. Chidule: Mitundu yosiyanasiyana yolumikizira ili ndi mawonekedwe awoawo, ndipo zofunikira kwa dalaivala ndizosiyana, makamaka ngati LED imodzi ikalephera kulephera ntchito yoyendera dera, kudalirika kowunikira konse, kuthekera koonetsetsa kuti ma LED onse atha, Kutha kupitiliza kugwira ntchito momwe mungathere, kutha kupitiliza kugwira ntchito, ndikofunikira kwambiri kuchepetsa kulephera kwathunthu kwa LED, etc. Zonsezi, ntchito zamagulu a LED ndi njira yofunikira pakugwiritsa ntchito kwenikweni kwa LED. Maulumikizidwe osiyanasiyana a LED ndi ofunikira kwa ma LED akulu akulu komanso zofunikira pakupanga mabwalo oyendetsa. Chifukwa chake, kuphatikiza mabwalo enieni, kusankha kolondola kwa njira yolumikizira yolumikizira ya LED kuli ndi tanthauzo labwino pakuwongolera momwe kuwala kwake kumathandizira, kudalirika kwa ntchito, kusavuta kwa mapangidwe ndi kupanga kwa oyendetsa, komanso magwiridwe antchito. dera lonse.
