Ndi Zabwino?

Sankhani gwero lounikira losawilitsidwa la LED. Gwero la kuwala kwa COB ndi ukadaulo wapamwamba kwambiri wophatikizira pamwamba womwe umalumikizidwa mwachindunji ndi gawo lachitsulo chagalasi pa chipangizo cha LED molunjika pamlingo wowunikira kwambiri. Tekinoloje iyi imachotsa lingaliro la bulaketi. Gwero la kuwala kwa LED lomwe lili ndi mphamvu zambiri zowunikira limaperekedwa, ndipo gawo limodzi likufunika kuti likhale ndi mphamvu zambiri zamagetsi ndi mphamvu. Ukadaulo wapadera wamagetsi a LED unayamba cha m'ma 2000, ndipo kukula kwake kunali kochedwa. Makampani apakhomo analibe pafupifupi kupanga, pamene mayiko akunja, Osram ndi Langamas okha, USA, angapereke. Kuwala kotulutsa kuwala komanso kuwala kowoneka bwino kwa gwero lophatikizika la kuwala kwa LED kumagwirizana ndi zida ndi njira zopangira ma LED. Pakalipano, pali mitundu itatu yofiira, yobiriwira, yabuluu (R, G, B). Chifukwa cha kutsika kwa magetsi a LED (1.5-3V yokha), imatha kuwunikira ndikuwala kwina, ndipo kuwalako kumatha kusinthidwa ndi magetsi (kapena apano). Pachida chowonetsera, palibe njira ina yowonetsera panopa komanso mawonekedwe a LED. Palibe electroplating, palibe backwalm, palibe chigamba ndondomeko, kotero ndondomeko yafupika pafupifupi gawo limodzi mwa magawo atatu, ndi mtengo komanso kupulumutsidwa ndi gawo limodzi mwa magawo atatu. Kodi gwero la kuwala kwa LED ndi chiyani? Anzanu omwe sadziwa bwino funsoli nthawi zambiri amafunsa anzawo omwe amadziwa bwino pulojekita. Poyerekeza ndi magwero achikhalidwe, kuchuluka kwa magwero a kuwala kwa LED ndikocheperako. Chifukwa chake, pali zambiri zazing'ono zowoneka bwino pamsika pano. Mapangidwe a kuwala kwa msewu wa LED ndi mawonekedwe achiwiri opangira mawonekedwe. Timawombera kuwala kwa magetsi a mumsewu wa LED kumalo komwe kuwala kukufunika, zomwe zingapangitse kuwalako kukhala koyenera. Magetsi amsewu a LED amakhala ndi moyo wautali wautumiki. Pambuyo pa zaka 10 zogwiritsidwa ntchito, magetsi a mumsewu a LED akadali ndi phindu lalikulu. Sali bwino ngati 3% pakugwiritsa ntchito mosalekeza kwa chaka chimodzi. Kuwala -emitting diodes ya nyali za mumsewu wa LED ndi chipangizo chochepa chamagetsi, chomwe ndi chotetezeka kugwiritsa ntchito magetsi. Monga kuwala kwamakono, makamaka gawo lapakati la ma optics ophatikizika, kuthamanga kwapamwamba kwambiri komanso magwero owunikira a laser nthawi zonse akhala akuyang'ana kwambiri maphunziro ndi mafakitale. Class B Strategic Pioneer Science and Technology Special mu Class B ya Chinese Academy of Sciences “Chip chachikulu cha Photon Integrated ”Ndi chithandizo, posachedwa, gulu laling'ono -nainer ndi Photon Integrated gulu la Xi'an Optical Machine. Gwero lophatikizika la kuwala kwenikweni ndi chifukwa gwero la kuwala kwa LED limatengedwa. Chifukwa chake, pakhoza kukhala mwayi woterewu. Gwero loyatsira lamba lachikhalidwe limafunikira malo okulirapo kuti lichotse kutentha. Ponena za magwero owunikira aulere a LED awa, nyali ya LED pan -light ndi gwero la madontho lomwe limatha kuwunikira mozungulira mbali zonse. Mtundu wake wa radiation ukhoza kusinthidwa mosasamala. Zogulitsa za kampaniyi zimagwiritsidwa ntchito kwambiri pakuwunikira kwa dzuwa, kuyatsa kwamatauni, zida zolumikizirana, chitetezo chamsewu ndi magawo ena, etc. Zogulitsa zazikulu zomwe zimapangidwa ndi: magetsi amisewu a dzuwa, magetsi amsewu, magetsi akubwalo, magetsi opangira magetsi a solar photovoltaic, nyali za LED, contour ya LED, nyali zamtundu wa LED, nyali zotayira za aluminiyamu, zowongolera zowonjezera mphamvu za dzuwa, owongolera owonjezera mphamvu ya dzuwa ndi mphamvu zina. zida zogawa. Chifukwa chachikulu cha kulephera kwakukulu ndi chikasu kapena kuchepetsa silicone kapena kuchepetsa. Ma elekitirodi a LED P ndi N ali mbali imodzi ya LED. Pakalipano iyenera kuyenda modutsa mulingo wa N-GAN mopingasa, zomwe zimapangitsa kuti pakhale kuchulukana kwamakono, kutentha kwapakati, ndikuchepetsa kuyendetsa galimoto. Kusowa. Pogwiritsa ntchito nthawi yayitali, kutentha kwakukulu komwe kumachitika chifukwa cha kutentha kosakwanira kumakhudza ntchito ndi kufalitsa kwa silikoni, zomwe zimapangitsa kuti magetsi awonongeke kwambiri. Integrated light source pan -light ndiye gwero lomwe limagwiritsidwa ntchito kwambiri pomasulira. Magetsi amtundu wa pan-light amagwiritsidwa ntchito kuunikira malo onse. Mutha kugwiritsa ntchito ma pan-light lights angapo powonekera kuti mupange zotsatira zabwino.
