N’chifukwa chiyani anthu ambiri amakonda kugwiritsa ntchito nyali za LED m’malo mogwiritsa ntchito nyali zoyaka incandescent?

Nawa mafaniziro ena, mwina angatithandize kupeza yankho.

Kusiyana koyamba pakati pa nyali za incandescent ndi nyali za LED ndi mfundo yotulutsa kuwala.Nyali ya incandescent imatchedwanso babu yamagetsi.Mfundo yake yogwira ntchito ndi yakuti kutentha kumapangidwa pamene panopa akudutsa mu filament.The spiral filament imasonkhanitsa kutentha kosalekeza, kupangitsa kutentha kwa filament kupitirira madigiri 2000 Celsius.Pamene ulusiwo uli mu incandescent state, umawoneka ngati chitsulo chofiira.Ikhoza kutulutsa kuwala monga momwe imawalira.

Kutentha kwapamwamba kwa filament, kuwala kowala kwambiri, motero kumatchedwa nyali ya incandescent.Pamene nyali za incandescent zimatulutsa kuwala, mphamvu zambiri zamagetsi zimasinthidwa kukhala mphamvu ya kutentha, ndipo gawo laling'ono lokha likhoza kusinthidwa kukhala mphamvu yowunikira yothandiza.

Magetsi a LED amatchedwanso ma diode otulutsa kuwala, omwe ndi zida zolimba za semiconductor zomwe zimatha kusintha magetsi kukhala kuwala.Mtima wa LED ndi chip cha semiconductor, mbali imodzi ya chip imamangiriridwa ku bulaketi, mapeto amodzi ndi mzati woipa, ndipo mapeto ena amagwirizanitsidwa ndi mtengo wabwino wa magetsi, kotero kuti chip chonse chimatsekedwa. ndi epoxy resin.

Chophika chophatikizira cha semiconductor chimapangidwa ndi magawo atatu, gawo limodzi ndi semiconductor yamtundu wa P, momwe mabowo amalamulira, malekezero ena ndi semiconductor yamtundu wa N, apa pali ma elekitironi, ndipo pakati nthawi zambiri ndi chitsime cha quantum chokhala ndi 1 mpaka 5. mikombero.Pamene panopa akugwira chip kudzera mu waya, ma elekitironi ndi mabowo adzakankhidwira mu zitsime za quantum.Mu zitsime za quantum, ma elekitironi ndi mabowo amalumikizananso kenako amatulutsa mphamvu mu mawonekedwe a photons.Iyi ndiye mfundo yotulutsa kuwala kwa LED.

Kusiyana kwachiwiri kuli mu kutentha kwa kutentha komwe kumapangidwa ndi awiriwo.Kutentha kwa nyali ya incandescent kumatha kumveka pakanthawi kochepa.Kuchuluka kwa mphamvu, kumatentha kwambiri.Mbali ya kutembenuka kwa mphamvu yamagetsi ndi kuwala ndi mbali ya kutentha.Anthu amatha kumva bwino kutentha komwe kumaperekedwa ndi nyali yoyaka pomwe ali pafupi kwambiri..

Mphamvu yamagetsi ya LED imasinthidwa kukhala mphamvu yowunikira, ndipo kutentha komwe kumapangidwa kumakhala kochepa kwambiri.Mphamvu zambiri zimasinthidwa mwachindunji kukhala mphamvu yowunikira.Komanso, mphamvu ya nyali zonse ndi yochepa.Kuphatikizidwa ndi kapangidwe ka kutentha kwapang'onopang'ono, kutentha kwa magwero a kuwala kwa LED kumakhala kwabwinoko kuposa kwa nyali za incandescent.

Kusiyana kwachitatu ndikuti magetsi opangidwa ndi awiriwa ndi osiyana.Kuwala kopangidwa ndi nyali ya incandescent ndi kuwala kwamitundu yonse, koma chiŵerengero cha maonekedwe a mitundu yosiyanasiyana ya magetsi amatsimikiziridwa ndi chinthu cha luminescent ndi kutentha.Chiŵerengero chopanda malire chimayambitsa kuwala kwa mtundu, kotero mtundu wa chinthu chomwe chili pansi pa nyali ya incandescent sichitha.

LED ndi gwero la kuwala kobiriwira.Nyali ya LED imayendetsedwa ndi DC, palibe stroboscopic, palibe zida za infrared ndi ultraviolet, palibe kuipitsidwa kwa radiation, kutulutsa kwamitundu yayitali komanso kuwongolera kowala kowala.

Osati zokhazo, kuwala kwa LED kumakhala ndi ntchito yabwino ya dimming, palibe cholakwika chowonekera pamene kutentha kwa mtundu kumasintha, ndipo gwero la kuwala kozizira limakhala ndi mbadwo wochepa wa kutentha ndipo ukhoza kukhudzidwa bwino.Itha kupereka malo abwino owunikira komanso abwino Ndiwo nyali yathanzi yomwe imateteza maso komanso ndi chilengedwe kuti ikwaniritse zosowa za thupi la anthu.
