Fomu yolumikizira mikanda ya LED, Common Failure Solution ya LED Light Emitting Modules

Mikanda ya nyali ya LED Njira zofananira zolumikizirana 1. Mawonekedwe onse olumikizirana (1) Mafomu osavuta angapo Nthawi zambiri mawonekedwe olumikizirana osavuta a LED1 LEDN amalumikizidwa koyambirira ndi mchira, ndipo omwe akuyenda nthawi ya LED ndi ofanana. Kwa ma LED omwe amafanana ndi magulu, ngakhale magetsi pa LED imodzi akhoza kukhala ndi kusiyana pang'ono, chifukwa LED ndi chipangizo chamakono, ikhoza kuonetsetsa kuti mphamvu yawo yowala imakhala yosasinthasintha, imagwira izi, mitundu yosavuta ya mawonekedwe a mapangidwe. LED ili ndi mawonekedwe a dera losavuta komanso kulumikizana kosavuta. Komabe, chifukwa cha kugwiritsidwa ntchito kwa mndandanda, pamene imodzi mwa ma LED ikuchitika, nyali zonse za LED zidzazimitsidwa, zomwe zidzakhudza kudalirika kwa ntchito. (2) Mitundu yotsatizana ya diode iwiri yokhala ndi kuphatikiza kwa diode ya Qina imalumikizidwa ndi mawonekedwe olumikizana amtundu wa Qiner 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, panopa makamaka ikuyenda mwa LED1 LEDN. Pamene LED yowonongeka mu chingwe cha LED imayambitsidwa Kuwonjezera pa zolakwika za LED, ma LED ena amakhalabe ndi mafunde kupyolera mumakono ndi kuwala. Njira yolumikizira iyi imapangidwa bwino kwambiri potengera kudalirika kofananira ndi kudalirika. Mawonekedwe ofananira (1) Mawonekedwe osavuta ofananira Osavuta komanso olumikizidwa a LED1 mutu ndi mchira wofanana, LED iliyonse ndi yofanana ndi 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, kusiyana kwa magwiridwe antchito ndikwachibadwa, kotero pamene LED1 LEDN ikugwira ntchito, aliyense amene amagwiritsa ntchito LED sali wofanana. Zitha kuwoneka kuti kugawa kosagwirizana kwa ma LED onse pakalipano kungapangitse kuti moyo wa LED wapano ukhale wokulirapo, komanso kupsa. Ngakhale njira yolumikizira iyi ndi yosavuta. Koma kudalirika si mkulu, makamaka ntchito pa nkhani ya kuchuluka kwa ma LED. (2) Mtundu wofananira wofananira wodziyimira umalimbana ndi kudalirika kwa kufanana kosavuta. Njira yofananira yofananira paokha ndi njira yabwino. LED iliyonse mwanjira imeneyi ili ndi magetsi osinthika (magalimoto a Voutput ndi L1 Ln, motsatana), ndikuwonetsetsa kuti magetsi akuyenda kudzera pa LED iliyonse ali mkati mwazofunikira zake, ndi zotsatira zabwino zoyendetsa, LED imodzi, LED imodzi. Kuteteza kwathunthu, sikumakhudza ntchito zina za LED zikalakwika, ndipo kumatha kufanana ndi mawonekedwe a ma LED okhala ndi kusiyana kwakukulu. Vuto lalikulu la kukhalapo ndi: mawonekedwe a dera lonse la dalaivala ndizovuta, mtengo wa chipangizocho ndi wokwera kwambiri, ndipo kuchuluka kwa ntchito ndikokwanira. Sikoyenera kuchuluka kwa mabwalo a LED. Mafomu ophatikizika-ophatikizidwa amaperekedwa pophatikiza maubwino otsatizana ndi mawonekedwe ofanana. Mafomu akuluakulu ndi awiri otsatirawa. (1) Pamene mafomu osakanikirana osakanikirana ali oyamba, chiwerengero cha ntchito za LED ndi zazikulu, ndipo mndandanda wosavuta kapena kugwirizana kofanana ndi kosatheka. Yoyamba imafuna kuti woyambayo apemphe voteji yokwera kwambiri (N nthawi za VF imodzi ya LED). Kuti mugwetse galimoto ndi magetsi akuluakulu (N nthawi za LED imodzi yamakono IF). Izi zimabweretsa zovuta pakupanga ndi kupanga dalaivala, komanso kumaphatikizanso zovuta zamapangidwe komanso magwiridwe antchito onse agalimoto. Mphamvu yogwira ntchito ya chiwerengero cha ma LED otsatizana ndi mphamvu yogwira ntchito ya LED VF imodzi imatsimikizira mphamvu yotulutsa mphamvu yoyendetsa; Mtengo wa NVF umatsimikizira mphamvu yotulutsa pagalimoto. 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 . Dera lonse limakhala ndi mawonekedwe osavuta, kulumikizana kosavuta, komanso kuchita bwino kwambiri. Ndizoyenera kugwiritsa ntchito ma LED ambiri. (2) Ma LED angapo omwe amasakanizidwa ndi chingwe cha mgwirizano choyamba ndiyeno ma skewers amakhala oyamba kenako ndi zingwe. 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 ndi mavuto omwe alipo a mawonekedwe osakanikirana awa ndi ofanana ndi. (3) Mitundu yamitundu yosiyanasiyana yamitundu yambiri imakhala yolimbikitsa 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. 2. Maulumikizidwe osiyanasiyana olumikizirana osiyanasiyana ali ndi mawonekedwe awoawo, ndipo zofunikira za dalaivala ndizosiyana, makamaka ngati LED imodzi imalephera kulephera ntchito yadera, kudalirika kowunikira konse, ndikuwonetsetsa kuti ma LED onse amatha kukhala momwe angathere. momwe tingathere. Ndikofunikira kwambiri kupitiliza luso la ntchito ndikuchepetsa kulephera kwathunthu kwa LED, ndi zina zambiri. 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. Kulephera kwa gawo lowala la LED ndi njira yothetsera: kuwala konse kwa LED; Funso: kusalumikizana bwino; yankho: kukonzanso kapena kuyika; chodabwitsa: kuwala kwa LED; Funso: 1. M’madera m’madera m’madera m’madera a m’madera a m’madera a m’madera a m’madera a m’madera. LED ndi yayitali kwambiri kuti ikhale yayitali; 3. Kusintha kwamagetsi sikukugwirizana ndi chizindikiro cha magetsi a LED; Kuwala; Funso: 1. Kaya mayendedwe olowetsamo ndi olondola; 2. Kaya mawaya otulutsa mphamvu ndi olondola; 3. Chingwe chamagetsi chimamangirira ndikubwerera; yankho: 1. Disassemble , Mawaya akuda amalumikizidwa ndi mitengo yoyipa; 3. Pezani gawo la mizere yopingasa; kugwirizanitsanso; chodabwitsa: Ma LED onse sali owala; Funso: 1. Palibe kutulutsa kwamagetsi kwamagetsi osinthira; 2. Kaya mawotchi otulutsa magetsi osinthika ndi olondola; yankho: 1, Yesani -ku-mphamvu yofikira kusintha kolowera magetsi; 2. Mawaya amagetsi zabwino ndi zoipa mizati zolondola;
