Nchiyani Chimachititsa Chip choyera cha LED Kufa?

Opanga ambiri amangogwiritsa ntchito zida zotsika mtengo komanso zotsika mtengo kuti achepetse mitengo ya nyale kuti akope makasitomala. Kuchuluka kwa madandaulo amtundu wa nyali za WHITE LED kwakwera zaka ziwiri zapitazi chifukwa cha izi. Kuwoneka kwachikasu kwapanja ndi chimodzi mwa izo, ndipo ndizoyipa kwambiri. Tikambirana zomwe zimayambitsa Wova woyera LED chip  Kufa. Popanda kuchedwa, tiyeni tilowe mkati.

Kodi Ndi Chiyani woyera LED chip ?

Kupanga kuwala koyera ndi ma LED WOYERA kumatha kuchitika m'njira ziwiri zosiyana. Njira ya RGB ndiyo yoyamba, ndipo njira ya phosphor ndi yachiwiri. Njira ya phosphor ndiyomwe imagwiritsidwa ntchito kwambiri pagawo lowunikira. Njira ya phosphor imapanga phukusi la WHITE LED lomwe limapanga kuwala koyera povala buluu woyera LED chip ndi phosphor yachikasu.

Kupanga kuwala koyera ndi ma LED WOYERA kumatha kuchitika m'njira ziwiri zosiyana. Njira ya RGB ndiyo yoyamba, ndipo njira ya phosphor ndi yachiwiri. Njira ya phosphor ndiyomwe imagwiritsidwa ntchito kwambiri pagawo lowunikira.

Mwa kungophatikiza nyali zofiira, zobiriwira, ndi zabuluu mumlingo woyenera, kuwala koyera kumapangidwa pogwiritsa ntchito njira ya RGB.

Njira ya phosphor imapanga phukusi la WHITE LED lomwe limapanga kuwala koyera povala buluu woyera LED chip  ndi phosphor yachikasu. The yellow fulorosenti wosanjikiza amalola kuwala buluu kwaiye ndi woyera LED chip  kudutsa, kupanga kuwala koyera ndi kusakaniza kwa blues ndi yellow photon.

Pamlingo wa chip, diode yotulutsa kuwala (LED) imakhala ndi zida za semiconductor zomwe zapangidwa kuti zipange p-n mphambano. Pogwiritsa ntchito kutsogolo kwa tsankho pamphambano, munthu akhoza kukakamiza ma elekitironi kuchoka ku gulu la n-mtundu wa conduction band kupita ku gulu la p-mtundu wa conduction. Kubwezeretsanso uku ndi njira yowunikira yomwe, nthawi zambiri, imapangitsa kupanga photon yokhala ndi kutalika kwa mawonekedwe omwe amatsimikiziridwa ndi bandgap ya zinthuzo.

Pambuyo pakupanga mawonekedwe a WHITE LED  chowotcha, chimadulidwa motsatira, ndipo munthu akafa yemwe amapanga mkatewo amalumikizidwa ndi kupakidwa. Ndikofunikira kulumikiza LED WOYERA  kumatsogolere pogwiritsa ntchito mawaya abwino kwambiri, omwe nthawi zambiri amakhala opangidwa ndi golide, kuti apange kutsogolo komwe kuli kofunikira kuti pakhale kuwala kwa WHITE LED.

Chifukwa chiyani? woyera LED chip s Kufa?

Ma LED WOYERA nthawi zambiri amakumana ndi mitundu iwiri ikuluikulu yakulephera: kupita patsogolo kapena tsoka. Kulephera kwa LED WOYERA  nthawi zambiri amayamba chifukwa cha kuchepa kwapang'onopang'ono pakapita nthawi kusiyana ndi kusintha kwadzidzidzi, kupatulapo zochepa kwambiri. Kulephera, pamaso pa ogulitsa, si chikhalidwe cha mayiko awiri koma m'malo mwake ndi mfundo yowonjezereka pa kupitiriza kwa machitidwe. Malinga ndi kafukufuku, diso la munthu limatha kuzindikira kusintha kwa 30 peresenti mu kuwala kowala kwambiri kusanatuluke kwa nyali. Chifukwa cha izi, ambiri opanga amatanthauzira moyo wa chipangizocho monga momwe kuwala kwake kumatsikira pansi pa 70 peresenti ya mtengo womwe unali nawo poyamba.

Komabe, izi sizikutanthauza kuti kulephera koopsa sikudzachitika. M'malo mwake, mwayi woti chida chanu chimodzi chidzasiya kugwira ntchito bwino nthawi ina chimawonjezeka molingana ndi kuuma kwa magwiridwe antchito. Pali, komabe, zomwe mungachite kuti muchepetse zovuta zambiri mwazinthu izi ndikuwonjezera mwayi woti ntchito yanu ivomerezedwe.

Zolephera zakuthupi

WHITE LED  magwiridwe antchito ndi moyo wautali zimadalira mtundu wazinthu. Kuphatikizikanso kwa ma electron-hole kungayambitse kuwola kopanda kuwala ngati zinthuzo zili ndi zolakwika zambiri. Ma LED ambiri oyera oyera amapangidwa pamiyala ya safiro yokutidwa ndi GaN. Kusokonezeka kwa lattice kumapangitsa kuti ulusi usungunuke. Ming'alu zabwino zimafalikira molunjika kuchokera ku filimu ya GaN kupita kudera lomwe likugwira ntchito, zomwe zidayambitsa kuwola kopanda kuwala. Kutulutsa kwa nyali kumachepa ngati kuwola kopanda ma radiation kumawonjezeka. Thermocycling imatha kufalitsa zolakwika izi.

Kutayikira kwaposachedwa kuchokera ku zolakwika zamapangidwe kumapangitsa kuti kusinthaku kuyendetsedwenso. Jakisoni wonyamula kudzera m'dera logwira ntchito amatha kupanga kapena kufalitsa zolakwika. Kachulukidwe kachilema amachepetsa mphamvu yamagetsi, zomwe zimakhudza magwiridwe antchito.

Kukwera kwamphamvu kumatha kuyambitsa zolakwika pamphepete mwa p-mbali. Kupsinjika kwamagetsi kunawononga ultraviolet WHITE LED s kuposa kupsinjika kwamafuta. Malingaliro a kampani Zhuhai Tianhui Electronic Co., Ltd.   zoyera zoyera za LED ndizoyenera kugwiritsa ntchito zowala kwambiri. Chida chokwera pamwamba chimatha kugwira 2.8 A kutsogolo kwa 900 lm kutulutsa.

Kuyendetsa mopitilira muyeso wa LED WOYERA

Kuyendetsa mopitilira muyeso wa LED WOYERA  ikhoza kuwononga zotulutsa ndi moyo wonse. Pazinthu zowala kwambiri, tchulani chipangizo chonga cha LED yoyera bwino iyi, yomwe imatha kutulutsa 900 lm pa 2.8 A.

WHITE LED  zolakwika sizimangokhala pa media media. Epoxy encapsulate imateteza kufa, koma imatha kuyambitsa mavuto. Zomwe zimayamwa zimatha kusamutsa chinyontho kapena ma caustic makemikolo ku kufa komwe kumakhala chinyezi kapena dzimbiri. Zowonongeka zowonongeka zimatha kupanga zazifupi kapena overvoltage. Kuphatikizika kumatha kuchepetsa izi, koma zida ziyenera kutetezedwa potentha komanso chinyezi.

Kuwonongeka kwamagetsi

Electromigration, njira yodziwikiratu yomwe imapangidwa ndi chinyezi kapena chinyezi, imatha kutulutsa ulusi kuchokera kuzitsulo ngati siliva wopaka phala womwe umagwiritsidwa ntchito kumatira ma LED okwera pama board. Pewani ma LED omwe sali otsekedwa.

WHITE LE D kuwululidwa ndi high-voltage electrostatic discharge akhoza kulephera mwatsoka. Ma spikes a Ultra-high-voltage ndiofala. Kuyenda m'chipinda chokhala ndi kapeti kumatha kukulipirani mpaka 1.5 kV, kutengera chinyezi ndi nsapato. Kugwedezeka kumeneko kumatha kugonjetsa semiconductor material electrostatic resistance ikaperekedwa ku imfa. Kutentha kwambiri komwe kumachitika chifukwa cha zotulutsa kumatha kusokoneza media, kupangitsa kulephera kwafupipafupi.

Kumene Mungagule Choyera woyera LED chip  Zimenezo Zimatenga Nthawi Yaitali

Malingaliro a kampani Zhuhai Tianhui Electronic Co., Ltd.  ndi wapamwamba kwambiri UV Opanga LED  okhazikika pa UV WHITE LED drive air sanitization, UV WHITE LED yoyeretsa madzi pagalimoto, UV WHITE LED yosindikiza yosindikiza, UV White LED diode , uv   Chid Ml , ndi zinthu zina. Ili ndi akatswiri ofufuza ndi chitukuko ndi ogwira ntchito kuti apatse makasitomala ma UV WHITE LED drive Arrangement, ndipo zogulitsa zake zalandiranso kuvomerezedwa kwamakasitomala ambiri.

Tianhui Hardware yakhala gawo la UV WHITE LED drive phukusi yokhala ndi mndandanda wathunthu wopanga, mawonekedwe osasinthika komanso kulimba, komanso mitengo yotsika. Zidazi zikuphatikiza UVA, UVB, ndi UVC kuchokera kufupi kupita kufupipafupi komanso zambiri za UV Radiation kuyambira kutsika mpaka kumphamvu kwambiri.
