Kuwonetsera kwa LED ndi mtundu watsopano wa zida zowonetsera, zimakhala ndi ubwino wambiri poyerekeza ndi njira zowonetsera zachikhalidwe, monga moyo wautali wautumiki, kuwala kwakukulu, kuyankha mofulumira, mtunda wowonekera, kusinthasintha kwakukulu kwa chilengedwe ndi zina zotero.Mapangidwe aumunthu amapangitsa kuti chiwonetsero cha LED chikhale chosavuta kukhazikitsa ndi kukonza, chitha kugwiritsidwa ntchito nthawi iliyonse komanso kulikonse mosinthika, koyenera kuyika zinthu zambiri, mawonekedwe amakwaniritsidwa ndi chithunzi, kapena kupulumutsa mphamvu ndi kuchepetsa umuna, mtundu wa zinthu zobiriwira zoteteza chilengedwe.Ndiye, moyo wautumiki wa zowonetsera zonse za LED ndi utali wotani?
Kugwiritsa ntchito chiwonetsero cha LED kungagawidwe mkati ndi kunja.Tengani chiwonetsero cha LED chopangidwa ndi Yipinglian mwachitsanzo, kaya m'nyumba kapena panja, moyo wautumiki wa gawo la LED ndi maola opitilira 100,000.Chifukwa kuwala kwambuyo nthawi zambiri kumakhala kuwala kwa LED, moyo wa backlight ndi wofanana ndi wa skrini ya LED.Ngakhale atagwiritsidwa ntchito maola 24 pa tsiku, chiphunzitso chofanana cha moyo ndi zaka zoposa 10, ndi theka la moyo wa maola 50,000, ndithudi, izi ndi mfundo zongopeka!Zimatenga nthawi yayitali bwanji zimatengeranso chilengedwe komanso kukonza zinthu.Kusamalira bwino ndi kukonza njira ndiyo njira yofunikira yamoyo yowonetsera ma LED, chifukwa chake, ogula kuti agule zowonetsera za LED ayenera kukhala ndi khalidwe ndi ntchito monga maziko.
Zinthu zomwe zimakhudza moyo wa chiwonetsero cha LED
Ife tonse tikudziwa kuti ntchito tchipisi zabwino, zipangizo zabwino, ambiri LED anasonyeza moyo ntchito si lalifupi, osachepera adzakhala ntchito kwa zaka zoposa ziwiri.Komabe, pogwiritsira ntchito, nthawi zambiri timakumana ndi mavuto osiyanasiyana, makamaka mawonetsedwe a LED omwe amagwiritsidwa ntchito panja, nthawi zambiri amavutika ndi mphepo ndi dzuwa, komanso nyengo yoipa kwambiri.Choncho, n'zosapeŵeka kuti padzakhala mavuto osiyanasiyana, zomwe zidzakhudza moyo wautumiki wa chiwonetsero chamtundu wa LED.
Ndiye ndi zinthu ziti zomwe zingakhudze moyo wautumiki wa chiwonetsero cha LED?Kunena zoona, palibe zinthu zoposa ziwiri, zoyambitsa zamkati ndi zakunja za mitundu iwiri;Zifukwa zamkati ndikugwira ntchito kwa zida zotulutsa kuwala kwa LED, magwiridwe antchito a zida zotumphukira, ntchito yolimbana ndi kutopa kwa chinthucho, komanso zifukwa zakunja ndi malo ogwirira ntchito a chiwonetsero cha LED.
Zida zopangira kuwala kwa LED, ndiko kuti, nyali za LED zomwe zimagwiritsidwa ntchito pazenera, ndizofunika kwambiri komanso zokhudzana ndi moyo pazithunzi zowonetsera.Kwa LED, timalabadira zizindikiro zotsatirazi: makhalidwe attenuation, makhalidwe nthunzi kulowa madzi, odana ndi ultraviolet ntchito.Kuchepetsa kuwala ndi mawonekedwe achilengedwe a ma LED.Kwa chinsalu chowonetsera chokhala ndi moyo wa zaka 5, ngati kuwala kwa kuwala kwa LED komwe kumagwiritsidwa ntchito ndi 50% m'zaka 5, malire ochepetsetsa amayenera kuganiziridwa pamapangidwe, apo ayi kuwonetserako sikungafike pamlingo pambuyo pa zaka 5.Kukhazikika kwa index yowola nakonso ndikofunikira kwambiri.Ngati kuwonongeka kupitirira 50% m'zaka 3, zikutanthauza kuti moyo wa chinsalu udzatha msanga.Choncho pogula anasonyeza LED, ndi bwino kusankha wabwino Chip, ngati Riya kapena Kerui, izi akatswiri LED Chip opanga, osati khalidwe labwino, komanso ntchito zabwino.
Kuwonetsera panja nthawi zambiri kumakokoloka ndi chinyezi mumlengalenga, Chip cha LED cholumikizana ndi nthunzi yamadzi chimayambitsa kupsinjika kapena kachitidwe ka electrochemical kumapangitsa kuti chipangizocho chilephereke.Nthawi zonse, chipangizo chotulutsa kuwala kwa LED chimakulungidwa mu epoxy resin ndikutetezedwa ku kukokoloka.Zida zina za LED zokhala ndi zolakwika zamapangidwe kapena zolakwika zakuthupi ndi ndondomeko zimakhala ndi ntchito yosasindikiza bwino, ndipo nthunzi yamadzi imalowa mosavuta pa chipangizocho kupyolera mumpata pakati pa pini kapena kusiyana pakati pa epoxy resin ndi chipolopolo, zomwe zimapangitsa kuti chipangizochi chiwonongeke mofulumira, chomwe chimatchedwa " nyali yakufa” m’makampani.
Kuonjezera apo, pansi pa kuwala kwa ultraviolet, colloid ya LED, zinthu zakuthupi zothandizira zidzasintha, zomwe zimapangitsa kuti chipangizochi chiwonongeke, kenako chidzakhudza moyo wa LED.Chifukwa chake, kukana kwa UV kwakunja kwa LED ndi chimodzi mwazinthu zofunika kwambiri.Kotero kugwiritsa ntchito kunja kwa LED kuwonetsera chithandizo chamadzi - kuyenera kugwira ntchito yabwino, mlingo wa chitetezo kuti ufike IP65 ukhoza kukwaniritsa madzi, fumbi, chitetezo cha dzuwa ndi zotsatira zina.
Kuphatikiza pa zida zopangira kuwala kwa LED, chiwonetsero chowonetsera chimagwiritsanso ntchito zida zina zambiri zotumphukira, kuphatikiza matabwa ozungulira, nyumba zapulasitiki, magetsi osinthira, zolumikizira, nyumba, ndi zina. Mavuto aliwonse amagulu, angayambitse kuchepetsedwa kwa moyo wowonetsa.Chifukwa chake zingakhale zomveka kunena kuti moyo wautali kwambiri wa chiwonetsero cha LED umatsimikiziridwa ndi moyo wa chinthu chachifupi kwambiri.Choncho n’kofunika kwambiri kusankha nkhani yabwino.
Kuchita zotsutsana ndi kutopa kwa zinthu zowonetsera kumadalira njira yopangira.Ndizovuta kutsimikizira ntchito yolimbana ndi kutopa kwa module yopangidwa ndi njira yosauka yaumboni itatu.Pamene kutentha ndi chinyezi zikusintha, malo otetezera a bwalo lozungulira adzasweka, zomwe zimapangitsa kuwonongeka kwa ntchito zoteteza.Choncho, kugulidwa kwa chiwonetsero cha LED kuyenera kuganizira opanga akuluakulu, opanga mawonetsero a LED omwe ali ndi zaka zambiri adzakhala othandiza kwambiri pakuwongolera kupanga.
LED njira zisanu ndi imodzi zosamalira
Pakalipano, chiwonetsero cha LED chakhala chikugwiritsidwa ntchito kwambiri m'makampani amitundu yonse, zomwe zikubweretsa ubwino wambiri m'moyo wa anthu.Mabizinesi ambiri adzagwiritsa ntchito chiwonetsero cha LED, ndipo mabizinesi ena amagula zambiri, monga mabizinesi ogulitsa nyumba, malo owonetsera makanema ndi zina zotero.Ngakhale mabizinesi agula zinthu, anthu ambiri sadziwa kuzisamalira ndikuzigwiritsa ntchito.
Mawonekedwe a LED akuwonetsa mawonekedwe amkati amkati amayendedwe okhazikika.Zikapezeka kuti pali zida zowonongeka ndi zina zovuta, ziyenera kusinthidwa nthawi, makamaka zitsulo zazitsulo zazitsulo zing'onozing'ono;Polandira chenjezo la masoka achilengedwe monga nyengo yoipa, m'pofunika kuyang'ana bata ndi chitetezo cha gawo lililonse la chinsalu.Ngati pali vuto lililonse, liyenera kuthetsedwa munthawi yake kuti mupewe zotayika zosafunikira;Nthawi zonse sungani zokutira pamwamba pa chiwonetsero cha LED ndi mfundo zowotcherera zitsulo kuti mupewe dzimbiri, dzimbiri ndi kugwa;Zowonetsera za LED zimafuna kukonzedwa pafupipafupi, osachepera kawiri pachaka.
Kuyang'anira zinthu zosalongosoka: kuti zinthu zomwe zili ndi vuto ziziyang'aniridwa nthawi zonse, kukonza nthawi yake kapena kusinthidwa, nthawi zambiri miyezi itatu kamodzi.
Kuwonetsera kwa LED pakukonza, nthawi zina kumafunika kuyeretsa kuwala kwa LED.Mukatsuka nyali ya LED, sukani pang'onopang'ono fumbi lomwe lasonkhana kunja kwa chubu la LED ndi burashi yofewa.Ngati ndi bokosi lopanda madzi, lingathenso kutsukidwa ndi madzi.Malinga ndi kugwiritsa ntchito malo owonetsera ma LED, tiyenera kuyeretsa ndikukonza pafupipafupi kuti tiwonetsetse kuti chinsalu chonse chimagwira ntchito mokhazikika.
Ma LED amawonetsa chitetezo cha mphezi kuti ayang'ane nthawi zambiri.Onetsetsani ndodo yamphezi ndi mzere wapansi nthawi zonse;Pazochitika bingu ayenera kuyesedwa pa chitoliro, ngati kulephera, ayenera m'malo mu nthawi;Itha kuyang'aniridwa pafupipafupi pakagwa mvula yamphamvu.
Yang'anani dongosolo loperekera mphamvu la gulu lowonetsera.Choyamba, ndikofunikira kuyang'ana ngati malo olumikizirana nawo gawo lililonse mubokosi logawa ndi dzimbiri kapena lotayirira.Ngati pali vuto lililonse, ndikofunikira kuthana nalo munthawi yake.Kwa chitetezo, kuyika kwa bokosi lamagetsi kuyenera kukhala koyenera komanso kufufuzidwa nthawi zonse.Zingwe zamagetsi zatsopano ndi zizindikiro ziyeneranso kuyang'aniridwa pafupipafupi kuti zisaphwanye khungu kapena kulumidwa;Njira yonse yoperekera mphamvu zamagetsi iyeneranso kuyang'aniridwa kawiri pachaka.
Kuwunika kwa dongosolo la LED.Pa makina owongolera a LED, malinga ndi momwe zinthu ziliri kale, ntchito zake zosiyanasiyana zimayesedwa;Mizere yonse ndi zida zowonekera ziyenera kuyang'aniridwa pafupipafupi kuti zipewe ngozi;Yang'anani kudalirika kwa dongosolo nthawi zonse, monga kamodzi pa masiku asanu ndi awiri aliwonse.
Chida chilichonse chimakhala ndi moyo wautumiki, chiwonetsero cha LED sichimodzimodzi.Moyo wa chinthu sichimangokhudzana ndi ubwino wa zipangizo zake zopangira komanso teknoloji yopangira, komanso yogwirizana kwambiri ndi kukonza kwa People's Daily.Kuti tiwonjezere moyo wautumiki wa chiwonetsero cha LED, tiyenera kukhala ndi chizolowezi chosamalira mawonetsedwe a LED pakugwiritsa ntchito, ndipo chizolowezichi chimapita mozama m'mafupa, kupitirizabe.
