Ine: Kodi ma LED ndi chiyani?
Gwero lowala pambuyo pa incandescent, nyali za fulorosenti, kupita ku chitukuko cha LED, LED ili ndi mphamvu yochepa yogwiritsira ntchito mphamvu, kuwala kwakukulu, mercury-free nontoxic, moyo wautali, chiyambi cha nthawi yomweyo, plasticity ndi ubwino wina, m'malo mwa gwero la kuwala kwachikhalidwe, m'nkhaniyi sachita zambiri pa gwero kuwala mwambo kuti tionenso.
Otchedwa LED ndi Light Emitting diode chidule, ndiko kuti, kuwala-emitting diode, ndi semiconductor kuwala-emitting zipangizo, pamene malekezero awiri kuphatikiza kutsogolo voteji, zonyamula semiconductor mu pawiri chifukwa cha photon umuna ndi kutulutsa kuwala.LED imatha kutulutsa mwachindunji zofiira, zachikasu, buluu, zobiriwira, zabuluu, lalanje, zofiirira, zoyera.
II: Kapangidwe ka mikanda yowala ya LED
1, gwero la kuwala kwa LED ndi bulaketi, chip, guluu, phosphor, kapangidwe ka waya
2, bulaketi ya LED nthawi zambiri imapangidwa ndi mkuwa (palinso chitsulo, aluminiyamu ndi ceramic, etc.), chifukwa madutsidwe amkuwa ndi abwino kwambiri, amakhala ndi chiwongolero mkati, kulumikiza maelekitirodi mkati mwa mikanda yoyendetsedwa.
3, waya wowala kwambiri amagwiritsidwa ntchito 0.999 waya wagolide, m'mimba mwake: 0.8mil, 1.0mil.ena kufunafuna otsika mtengo opanga ndi mkuwa aloyi doped waya kuchita.
4, phosphor iyenera kutengapo gawo pakusintha kutentha kwamtundu wa gwero lowala.
5, tchipisi tapamwamba kwambiri ndi: United States CREE (Core), Bridgelux (Bridgelux);Japan Nichia (Nichia), Germany Osram Osram;Taiwan: Epistar.
III: Magwero a kuwala kwa LED
Msika nthawi zambiri umafalitsidwa mitundu ya LED ndi 2835, 5050, 5730, 5630, 3030, 4040, 7030 ndi COB yophatikizika ndi mikanda yamphamvu kwambiri, kusiyanitsa mtundu wowunikira umatchulidwa kutalika ndi m'lifupi mwa SMD SMD, mwachitsanzo. , chithunzi chotsatira cha 2835 SMD, ndiko kuti, m'lifupi mwake 2.8 yaitali 3.5, kuwala kotereku kumagwiritsidwa ntchito kwambiri mu mababu a LED, zounikira, zowunikira, magetsi a denga, zingwe zounikira Zowunikirazi zimagwiritsidwa ntchito kwambiri mu mababu a LED, zowunikira, zounikira, zounikira padenga, zowunikira, machubu ndi zina zotero.Mphamvu iliyonse kuposa 0.1W-1W.
Mikanda yamphamvu kwambiri imagwiritsidwa ntchito kwambiri pa 1W, 2W, 3W iliyonse, yomwe imagwiritsidwa ntchito powunikira komanso kuyatsa panja.
Magetsi ophatikizika a COB amagwiritsidwa ntchito kwambiri mu nyali zamphamvu kwambiri monga ma spotlights, ma track lights ndi floodlights, chilichonse chili ndi mphamvu ya 5-50W.
