Bulu Lowala, Kuwala kwa LED, ndi LED COB, Ndiziyani?

Babu ndi chipangizo chomwe chimatembenuza mphamvu yamagetsi kukhala kuwala kowonetsa kapena kuyatsa. Pali mitundu yosiyanasiyana ya kuwala.

Nyali yowunikira imatulutsa kuwala powotcha ulusi wa tungsten kuti ukhale woyaka ndi mphamvu inayake yamagetsi, yotchedwa babu lamagetsi. Bulu la halogen ndi nyali ya incandescent yodzazidwa ndi halogen kapena mpweya wina wa inert.

Pomwe chotchedwa-chomwe chimatchedwa kuwala kwa LED chili ndi chowunikira-mitting diode (LED). Ma diode amamatira pamwamba pa bwalo lozungulira kuti apange gwero lowala, lomwe limatchedwa Chip LED. Chip chowongolera chimakhala ndi ngodya yayikulu yowala, mpaka madigiri 120-160, koma ndi kukula kocheperako, kutalika kwa moyo wautali, kuchita bwino kwambiri, kunjenjemera - kwaulere, ndikuchotsa cheza cha ultraviolet. Zimakhala ndi vuto limodzi lokha kuti zimatulutsanso kuwala kwa buluu. Kuwona kuwala kwa buluu nthawi yayitali kumawononga khungu ndi maso. Ndi zaka zachitukuko m'makampani a LED, mwamwayi, tili ndi Rg0 (mulingo wotetezeka wa kuwala kwa buluu) Chip cha LED tsopano, ndipo chitha kugwiritsidwa ntchito pa nyali kale.

LED COB ndi mtundu umodzi wa chip chowongolera. Ndiukadaulo wapamwamba - wophatikizira wowunikira womwe umayika mwachindunji ma LED pagawo lachitsulo lapamwamba-lowoneka bwino. Tekinoloje iyi imachotsa mabakiteriya, siifunikira electroplating, imachotsa kugulitsanso, ndikuchotsa njira ya SMT, kupulumutsa gawo limodzi mwa magawo atatu a njira zogwirira ntchito ndi ndalama zopangira.

Mawonekedwe a LED COB:

Ndi magwiridwe antchito amagetsi okhazikika, kapangidwe kake pamayendedwe, kuwala, ndi kutayika kwa kutentha ndi sayansi komanso zomveka. Ukadaulo wothira kutentha umatsimikizira kuti tchipisi ta LED zikhalabe kutsogolera kukonza kwa lumen (95%). Zimapanganso njira yopangira mawonekedwe achiwiri pazowunikira zowunikira, zomwe zimathandizira kuwunikira kwamitundu, yunifolomu yowunikira, kuchotsa madontho owunikira, ndikupanganso kuyatsa kwabwino ndi chilengedwe-kuunikira kochezeka. Kuphatikiza apo, ndiyosavuta kukhazikitsa ndikugwiritsa ntchito, kuchepetsa ndalama zolipirira.

Gwero la kuwala kwa COB LED tsopano likugwiritsidwa ntchito kwambiri pazowunikira, zowunikira, zowunikira, zowunikira mumsewu, ndi zina zowunikira.

Ubwino ndi kuipa kwa mababu otsogolera osinthika ndi nyali za LED zidzafotokozedwa mubulogu yotsatira!
