Kuwala kwazithunzi zazikulu za LCD ndi kuyatsa wamba kumalimbikitsa kukula

Mu 2015 ndi 2016, ndalama zamakampani owunikira zowunikira zakhalabe ndi kukula kwachiwerengero chimodzi, koma mu 2017 makampaniwa akuyembekezeka kulimbikitsa kukula kwa ndalama za LED kuti afike pawiri.

iSuppli akulosera kuti wonse LED msika zolowa mu 2017 kukula ndi pafupifupi 13,7%, ndi pawiri pachaka kukula mlingo wa 2016-2012 adzakhala pafupifupi 14,6%, ndipo adzafika 12.3 biliyoni US madola ndi 2012. Mu 2015 ndi 2016, ndi Kuchuluka kwa msika wa LED padziko lonse lapansi kudangowonjezeka ndi 2.1% ndi 8.7% motsatana.

Nambalazi zikuphatikiza zida zonse zapamtunda (SMD) ndi phukusi lodutsamo magetsi a LED ndi ma alphanumeric display LEDs-kuphatikiza kuwala kokhazikika, kuwala kwambiri (HB) ndi ma ultra high lightness (UHB) ma LED.

Gawo lalikulu la kukula komwe kwatchulidwa pamwambapa kudzachokera ku kuwala kwapamwamba kwambiri ndi ma LED owala kwambiri omwe amagwiritsidwa ntchito powunikira.Pofika mchaka cha 2012, ma LED akuwala kwambiri adzawerengera pafupifupi 31% ya kuchuluka kwa ma LED, kupitilira 4% mu 2015.

Choyambitsa chachikulu cha kukula kwa msika

"Mugawo latsopano la kukula kwa LED, msika ukupitilizabe kufuna kwambiri kuyatsa kolimba kwa mabatani akumbuyo ndi zowonetsera zida zam'manja.Ichi ndiye chinthu chachikulu chomwe chimalimbikitsa kukula kwa msika wa LED, "adatero Dr. Jagdish Rebello, mtsogoleri ndi katswiri wamkulu wa iSuppli."Kuwunikira mkati mwagalimoto, komanso kuyatsanso kwa ma LCD azithunzi zazikulu zama TV ndi ma laputopu, misika yomwe ikubwerayi ilimbikitsanso kukula kwamakampani a LED.Kuphatikiza apo, kupititsa patsogolo ukadaulo wowunikira wokhazikika kumathandiziranso ma LED kuti apeze ntchito zatsopano pakuwunikira kokongoletsa ndi misika yowunikira zomangamanga.Malo a masewera a karati.”

LCD backlight akadali ntchito yayikulu ya LED

Posachedwa, zowonetsera zazing'ono za LCD ndi zowunikira zam'manja zam'manja zikadali msika waukulu kwambiri wama LED.Mu 2017, mapulogalamuwa adzawerengera zoposa 25% ya msika wonse wa LED.

LED imayang'ana zowunikira zazikulu za LCD

Kuyambira mchaka cha 2017, kuyatsa kwakumbuyo kwa ma LCD akuluakulu monga zolemba ndi ma TV anzeru a LCD akukhala njira yotsatira yofunikira ya ma LED.

Mtengo wa LCD backlight module (BLU) udakali wokwera kwambiri kuposa wachikhalidwe cha CCFL BLU, koma mtengo wa awiriwo ukuyandikira kwambiri.Ndipo LED BLU ili ndi maubwino ogwirira ntchito, monga kusiyanitsa kwakukulu, nthawi yosinthira mwachangu, mawonekedwe amtundu wamtundu, komanso kusowa kwa mercury kumathandizanso kuti itengedwe mu LCD.

Ena ogulitsa ma LED, opanga ma BLU, opanga ma panel a LCD ndi opanga ma TV/zowonetsera OEM tsopano ayamba kugwiritsa ntchito ma LED ngati nyali yakumbuyo ya ma LCD azithunzi zazikulu.Ma LCD azithunzi zazikulu pogwiritsa ntchito LED BLU ayambanso kutumiza malonda.

LED: Tsogolo la kuyatsa wamba

Kupanga ma LED owoneka bwino okhala ndi kuwala kopitilira 100 lumens/watt komanso kuwonekera kwazinthu zatsopano kwapangitsa ma LED kuti azigwira ntchito ndi masinthidwe apano popanda kufunikira kwa ma inverters, motero amakankhira ma LED kuyandikira msika wowunikira wamba.

Ma LED akhala akugwiritsidwa ntchito pazowunikira zosiyanasiyana zamkati ndi zakunja, ndipo ayamba kuyang'ana kwambiri pazowunikira zonse monga ma tochi, magetsi am'munda, ndi magetsi apamsewu.Kugwiritsa ntchito uku kukutsegulirani misika yakuwunikira kwa LED m'malo owunikira kunyumba ndi makampani.

Kuonjezera apo, dziko lapansi lawonjezera malamulo oletsa kugwiritsa ntchito nyali za incandescent ndikulimbikitsa kugwiritsa ntchito magetsi opulumutsa mphamvu.Posachedwapa, machubu a compact fluorescent (CFL) adzapindula ndi malamulo omwe amaletsa kugwiritsa ntchito nyali za incandescent.

Koma m'kupita kwanthawi, ubwino wa kuunikira kwa boma udzathetsa kusiyana kwa mtengo pakati pa ma LED ndi ma CFL.Ndipo momwe machitidwe a LED akupitilizira kuwongolera, kusiyana kwa mtengo kumachepetsedwanso.

iSuppli ikuneneratu kuti mu 2020 mababu a LED ayamba kugwiritsidwa ntchito pakuwunikira kwanyumba ndi makampani.
