Kuwala ndikupangidwa kwakukulu m'mbiri ya anthu, ndipo maonekedwe a kuwala kwa magetsi kwalimbikitsa kwambiri chitukuko cha anthu.
Nyali yoyamba yogwiritsidwa ntchito inali nyali ya incandescent, yomwe inapangidwa ndi misa yopangidwa ndi Thomas Alva Edison mu 1879. Nyali ya incandescent ndi mbadwo woyamba wa magetsi a magetsi, kuwala kwake kowala kumatha kufika pafupifupi 13%, kutulutsa bwino kwamtundu, mawonekedwe osalekeza, osavuta. kugwiritsa ntchito. Komabe, chifukwa mphamvu yotembenuza mphamvu ya nyali za incandescent ndizochepa, zimachotsedwa pang'onopang'ono ndi msika.
Ndi chitukuko cha anthu, nyali fulorosenti (nyali fulorosenti) anayamba kuonekera mu 1930s. Mu 1974, ufa wa fulorosenti wokhala ndi kuwala kofiira, wobiriwira ndi wabuluu unawonekera, ndipo kugwiritsa ntchito ngati zopangira nyali za fulorosenti kunapulumutsa mphamvu kwambiri. Nyali za fluorescent zimakhala ndi moyo wautali wautumiki, kuwala kowala kwambiri, malo ounikira akulu, ndipo zimatha kusinthidwa kukhala mitundu yosiyanasiyana yowala. Koma machubu a nyali za fulorosenti amawononga magetsi ambiri, ndipo magetsi ambiri amatenthedwa ngati kutentha.
Kenako nyali za sodium zapamwamba komanso nyali zachitsulo za halide zinatuluka, zomwe zimatchedwa magwero owunikira a m'badwo wachitatu. Nyali zapamwamba za sodium zimadziwika ndi kuwala kowala kwambiri, kugwiritsira ntchito mphamvu zochepa, moyo wautali, kulowa kwa chifunga champhamvu komanso kosavuta kumachita dzimbiri, ndi zina zotero. Ubwino wa nyali zachitsulo za halide ndikuti kuwala kowala kumakhala kokwera kwambiri, kuwala kowala kumakhala kokwera kwambiri mpaka 80-120Lm/W, cholozera chamitundu ndi chokwera, kutsika kwamtundu ndikwabwino, ndipo Ra imatha kufika 90. amagwiritsidwa ntchito powunikira m'nyumba zamabwalo, malo ogulitsira akuluakulu, mafakitale ogulitsa mafakitale, mabwalo amisewu, madoko ndi malo ena.
Chomaliza ndicho kuyatsa kwa semiconductor komwe kumagwiritsidwa ntchito kwambiri - kuyatsa kwa LED. Kutuluka kwa nyali za LED kwaphwanya lingaliro lachikhalidwe lopanga magwero a nyali, ndipo ndikusintha kwakukulu komwe kudayambanso babu itatha. Amagwiritsidwa ntchito mu nyali kuphulika-umboni mndandanda ndi nyali ambiri kuunikira mndandanda, makamaka woyera LED limodzi, kuwonjezeredwa ndi kusakanikirana kwa LED ndi SMD, kupanga misa nyali LED atapachikidwa, nyali LED nsanja ndi nyali zina mafakitale kuyatsa, kuswa malire a chikhalidwe kuunikira makampani kugonana. . Amagwiritsidwa ntchito kwambiri pakuwunikira kwa mafakitale chifukwa cha mawonekedwe ake opulumutsa mphamvu ndi kuteteza chilengedwe, kugwiritsa ntchito mphamvu pang'ono, kuwala kowala kwambiri, moyo wautali, wolimba komanso wokhazikika (wopanda madzi, osagwira fumbi, anticorrosion, osaphulika).
Munthawi yanzeru yazaka za 21st, msika wowunikira wanzeru ukuwonetsa kuthekera kwakukulu muzaka zingapo zikubwerazi. Ndi kupita patsogolo kwa nthawi, kusintha kwa nyali ndi nyali kukupitiriza, ndi kusintha kotani pa kuyatsa kwa LED, tidzadikira ndikuwona.
Zowoneka bwino zamkati mwamkatizi pamwambapa zikuchokera kuDongguan Mingpin photoelectric lighting company limited.
Ngati muli ndi chidwi ndi zinthuzi, chonde lemberani ogulitsa omwe ali pansipa, abwerera kwa inu posachedwa!
