Kuwunika Kwa Zida Zazikulu Za Mawonekedwe A matailosi a Pansi ya LED

Monga chigawo chachikulu cha machitidwe amakono a siteji, zowonetsera zamalonda, ndi zochitika zomwe zimagwirizanitsa, machitidwe ndi kulimba kwa mawonedwe a matayala a pansi a LED amatsimikiziridwa makamaka ndi zipangizo zomwe zimagwiritsidwa ntchito. Kuchokera pa core light-elementi yotulutsa mpaka kuchitetezo chakunja, chinthu chilichonse chimakhala ndi gawo lofunika kwambiri ndipo palimodzi chimazindikira mtundu wazinthu komanso moyo wake wonse.

 

Kuwala Kwambiri-Zigawo Zotulutsa: Nyali za LED ndi Chips Zoyendetsa

Ma matailosi a pansi a LED amadalira- nyali zowala kwambiri za LED, nthawi zambiri amagwiritsa ntchito ukadaulo wa gallium nitride (GaN)-based surface-mount package (SMD). Ma LEDwa amakhala ndi ma chips ofiira, obiriwira, ndi abuluu kuti awonetse{4}mitundu yonse. Kukana kwamagetsi kwa nyali, antistatic properties, ndi kukhazikika kwa kutentha kumakhudza mwachindunji machulukidwe amtundu ndi kusasinthasintha kwa chithunzicho. Chip chophatikizira choyendetsa nthawi zambiri chimagwiritsa ntchito IC yoyang'anira nthawi zonse kuti iwonetsetse kugawa komweku ndikupewa kuwonongeka kwa kuwala kwa pixel.

Gawoli ndi Circuitry: PCB ndi Insulation Equipment

Nyali zake zimagulitsidwa pa FR-4 gawo lapansi kapena aluminium copper clad laminate (MCPCB). Magetsi a aluminiyamu ndi amene amakonda kwambiri{{5}matailosi apansi amphamvu a LED chifukwa cha kutha kwa kutentha kwambiri. Wozungulira dera amasiyanitsidwa ndi epoxy resin insulation wosanjikiza kuteteza mabwalo lalifupi, pamene solder chigoba inki amateteza ziyangoyango kuti makutidwe ndi okosijeni. Zogulitsa zina zapamwamba-zimagwiritsa ntchito ma ceramic substrates kuti apititse patsogolo kutentha kwambiri.

Kutchinjiriza Packaging: Chishango ndi Kapangidwe ka Madzi

Kuti muwonetsetse kudalirika m'malo akunja kapena{0}}omwe mumadutsa magalimoto ambiri, ma LED ali ndi-chishango chapulasitiki cholimba kwambiri (monga PC kapena PMMA). Imakhala ndi kuwala kopitilira 90% komanso kukana mwamphamvu. Nyumba yonseyi imakhala yomangidwa ndi aluminiyamu yotuluka kunja kapena zitsulo, zodzazidwa ndi chinyezi{{5}silikoni wodziwikiratu, ndipo zomata ndi ma gaskets a rabara osalowa madzi a IP65 kuti azikhala olimba m'malo achinyezi.

Thandizo ndi Kuyanjana: Magalasi Otentha ndi Zomverera

Sikirini ya matailosi yapansi yolumikizana imakhala ndi gawo lophatikizika la sensa yapansi pansi ndi 6-10mm wandiweyani wagalasi wokhuthala kuti mugawire kupsinjika ndi kuyankha kukhudza. Makina a bracket nthawi zambiri amapangidwa ndi aluminiyamu alloy kapena chitsulo cha kaboni kuti atsimikizire kukhazikika kwa katundu.

Mwachidule, sikirini yowonetsera matailosi a pansi pa LED imapangitsa kuti pakhale kuwala, kusasunthika kwa nyengo ndi kutha kwa zinthu kudzera m'mapangidwe ogwirizana a zinthu zingapo, zomwe zimakwaniritsa zosowa za akatswiri-pamapulogalamu.
