Zotsatira za Mikanda ya Nyali ya LED pa Chiwonetsero

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. 1. Mtundu wonse wa mpambo 1. Mawonekedwe osavuta a mndandanda: Nthawi zambiri, LED1 LEDN mu mawonekedwe a mawonekedwe osavuta olumikizira amalumikizidwa mpaka kumapeto, ndipo yomwe ikuyenda kudzera mu 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. Mawonekedwe amdima ophatikizika a Qina diode: LED iliyonse imalumikizidwa ndi mawonekedwe olumikizidwa bwino a Qiner diode. 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. Fomu yofananira yosavuta: Yosavuta komanso yolumikizidwa ya mchira wa mutu wa LED1 LEDN yofanana, LED iliyonse ndi yofanana ndi voteji yofanana ya LED iliyonse. 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. Mawonekedwe ofananira odziyimira pawokha: Pazinthu zodalirika zofananira, mawonekedwe ofananirako 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. Mawonekedwe a kulumikiza kosakanikirana koyamba: Pamene kuchuluka kwa ntchito za LED kuli kwakukulu, mndandanda wosavuta kapena kulumikizana kofananira sikungatheke, chifukwa choyambirira chimafuna kuti dalaivala atulutse mphamvu yayikulu (N nthawi za VF imodzi ya LED), ndipo chomalizacho chimafuna kuti chomalizacho chimafuna kuti Drive litulutse mphamvu yayikulu (N nthawi za LED imodzi yapano IF). 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, choyamba chophatikizidwa ndi chingwe chosakanikirana chosakanikirana: Ma LED angapo anayamba kuphatikizidwa ndi chingwe cha mafomu osakanikirana osakanikirana. 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, mawonekedwe a mtanda: Mawonekedwe a mtanda ndi makamaka kupititsa patsogolo 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. Zhuhai Chit., Ltd. ndi katswiri wopanga mikanda ya nyali ya LED yokhala ndi zovomerezeka zingapo zadziko. Zogulitsa zazikuluzikulu zikuphatikizapo kuwala kofiirira kwa LED, mikanda ya nyali ya infuraredi ya LED, mikanda ya nyali ya ultraviolet, mikanda yamtundu wa LED, ndi zina zotero. Kukana kutentha kwakukulu, mphamvu zambiri. Tili ndi zaka 16 zakuchitikira patch ya LED. Kuthekera kopanga pamwezi ndi pafupifupi ma PC 60 miliyoni, ndipo zotulutsa zapachaka zimakhala pafupifupi ma PC 500 miliyoni. Amagwirizanitsa R & D, katundu ndi kugulitsa. 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.
