Kutalika kwa moyo wa nyali zamakampani a LED

Ukadaulo wapadera wa chip, sinki yotenthetsera yapamwamba kwambiri, ndi thupi la aluminium premium cast nyale zimatsimikizira moyo waNyali za mafakitale za LED, yokhala ndi moyo wautali wa chip wa maola 50,000. Komabe, ogula onse amafuna kuti kugula kwawo kukhale nthawi yayitali, ndipo nyali zamakampani a LED ndizosiyana. Ndiye kodi moyo wa nyali zamakampani a LED ungasinthidwe bwanji? Choyamba, mosamalitsa kulamulira khalidwe la LED zipangizo mafakitale ma CD ma CD, monga zomatira conductive, silikoni, phosphor, epoxy, kufa chomangira zipangizo, ndi magawo. Chachiwiri, rationally kupanga LED mafakitale nyali ma CD dongosolo; mwachitsanzo, kulongedza mopanda nzeru kungayambitse kupsinjika ndi kusweka. Chachitatu, kukonza njira zopangira nyali zamakampani a LED; mwachitsanzo, kuchiritsa kutentha, kuwotcherera kuthamanga, kusindikiza, kulumikiza kufa, ndi nthawi zonse ziyenera kutsatiridwa mosamalitsa malinga ndi zofunikira.

Kupititsa patsogolo moyo wa magetsi oyendetsa magetsi a mafakitale a LED, kusankha ma capacitor apamwamba kwambiri, a moyo wautali ndi njira yabwino yopititsira patsogolo mphamvu zoyendetsa galimoto; kuchepetsa ripple panopa ndi ntchito voteji ikuyenda kudzera capacitor; onjezerani mphamvu zamagetsi pagalimoto; kuchepetsa chigawo matenthedwe kukana; gwiritsani ntchito zotchingira madzi ndi njira zina zotetezera; ndi kulabadira kusankha zomatira thermally conductive.

Ubwino wa mapangidwe opangira kutentha ndi chinthu chofunikira kwambiri pa moyo wa nyali za migodi ya LED. Anthu ambiri amada nkhawa kuti nyali zamphamvu kwambiri za LED zimangokhala "zowala mochititsa mantha" koma zimatha kutsika kapena kulephera. Zowonadi, kukhudza kwenikweni kwa moyo wautali kumakhala pamapangidwe oletsa kutentha komanso mtundu wagwero la kuwala. M'malo ngati ma workshop omwe ntchitoyo imatenga nthawi yayitali, ngati nyaliyo siyingathe kutulutsa kutentha, kukalamba kwa chip kumathamanga, ndipo kuwala kumachepa mwachangu. Aluminium alloy fin mafin amagwiritsidwa ntchito m'mafakitale apamwamba kwambiri ndi nyali zamigodi kuti apititse patsogolo kayendedwe ka mpweya, kusunga zigawo zikuluzikulu mkati mwa kutentha koyenera ndikutalikitsa moyo wawo. Kutalika kwa nyali zokhala ndi mapangidwe osiyanasiyana kumatha kusiyana kwambiri, nthawi zina kambirimbiri, ngakhale tchipisi tamtundu womwewo tagwiritsidwa ntchito. Chotsatira chake, dongosolo la kutentha kwa nyali ndilofunika kwambiri pakupanga kwake. Kutentha kwa LED nthawi zambiri kumaphatikizapo kutayika kwa kutentha kwadongosolo ndi kutentha kwa phukusi. Mitundu yonse iwiri ya kutentha kwa kutentha iyenera kuganiziridwa panthawi imodzi kuti muchepetse kutentha kwa nyali. Pakupanga magwero a kuwala kwa LED, zida zoyikapo, zoyikamo, ndi njira zopangira zidapangidwa kuti zikwaniritse kutentha kwapaketi.

Pakadali pano, mitundu ikuluikulu yamapangidwe oziziritsira kutentha ndi ma silicon-based flip-chip structures, zitsulo zama board circuit board, ndi zida monga zida zomangira ndi ma epoxy resins. Kuwonongeka kwa kutentha kwadongosolo kumaphatikizapo kufufuza zaumisiri woyenerera kuti apange zatsopano ndi kukonza masinki otentha. Chifukwa chakuchulukirachulukira kwa ma LED amphamvu kwambiri, mphamvu zamagetsi zikukweranso. Pakadali pano, kutulutsa kutentha kwadongosolo kumagwiritsira ntchito njira ndi zida monga kuzirala kwa thermoelectric, kuziziritsa mapaipi otentha, ndi kuziziritsa mpweya mokakamiza. Kuthetsa vuto la kutentha kwa kutentha ndi njira yabwino yowonjezera moyo wa nyali za migodi ya LED, motero zimafuna kufufuza kwina ndi zatsopano.

Pamene machitidwe osiyanasiyana owunikira mafakitale ndi malo ogwirira ntchito akupitiriza kukonzanso ndi kukonzanso, mphamvu yopulumutsa mphamvu ya nyali za mafakitale ndi migodi ikuwonekera kwambiri, zomwe zimapangitsa kuti mafakitale ambiri azisankha ngati zowunikira. TIANXIANG imakhazikika mu kafukufuku, chitukuko, kupanga, malonda, ndi utumiki wa nyali za mseu LED, nyali migodi LED, ndiKuwala kwa dimba la LED, opereka apamwamba, ochita bwino kwambiriZida zogwiritsira ntchito LED.
