Kodi ma LED ndi chiyani ndipo amagwira ntchito bwanji?
LEDimayimirakuwala emitting diode.Zowunikira za LED zimatulutsa kuwala mpaka 90% mogwira mtima kuposa mababu a incandescent.Kodi zimagwira ntchito bwanji?Mphamvu yamagetsi imadutsa mu kachipangizo kakang'ono, komwe kamaunikira tinthu tating'onoting'ono tomwe timatcha ma LED ndipo zotsatira zake zimakhala kuwala kowoneka.Kuti mupewe zovuta zogwirira ntchito, ma LED otentha amatulutsa amalowetsedwa mumadzi otentha.
Moyo wa Zida Zowunikira za LED
Moyo wothandiza wa zowunikira za LED zimatanthauzidwa mosiyana ndi zowunikira zina, monga incandescent kapena compact fluorescent lighting (CFL).Ma LED nthawi zambiri "sawotcha" kapena kulephera.M'malo mwake, amawona 'kutsika kwa lumen', momwe kuwala kwa LED kumachepera pang'onopang'ono pakapita nthawi.Mosiyana ndi mababu a incandescent, "nthawi yamoyo" ya LED imakhazikitsidwa potengera nthawi yomwe kuwala kumachepa ndi 30 peresenti.
Kodi Ma LED Amagwiritsidwa Ntchito Motani Powunikira?
Ma LED amaphatikizidwa mu mababu ndi zida zopangira zowunikira wamba.Zing'onozing'ono, ma LED amapereka mwayi wapadera wopanga.Mayankho ena a mababu a LED amatha kufanana ndi mababu odziwika bwino ndipo amagwirizana bwino ndi mawonekedwe a mababu achikhalidwe.Zowunikira zina za LED zitha kukhala ndi ma LED omangidwamo ngati gwero lanthawi zonse.Palinso njira zosakanizidwa zomwe "bulb" yosakhala yachikhalidwe kapena mtundu woyatsa wosinthika umagwiritsidwa ntchito ndikupangidwira mwapadera mawonekedwe.Ma LED amapereka mwayi waukulu wopanga zinthu zatsopano zowunikira komanso kukwanira kugwiritsa ntchito zambiri kuposa matekinoloje achikhalidwe.
Ma LED ndi Kutentha
Ma LED amagwiritsa ntchito masinki otentha kuti atenge kutentha komwe kumapangidwa ndi LED ndikuutaya kumalo ozungulira.Izi zimalepheretsa ma LED kuti asatenthedwe komanso kupsa.Kuwongolera kwamafuta nthawi zambiri ndichinthu chofunikira kwambiri pakuchita bwino kwa LED pa moyo wake wonse.Kutentha kwapamwamba komwe ma LED amayendetsedwa, kuwalako kumawonongeka mofulumira, ndipo moyo wothandiza udzakhala wamfupi.
Zogulitsa za LED zimagwiritsa ntchito mitundu yosiyana siyana yoyatsira kutentha ndi masanjidwe ake kuti azitha kutentha.Masiku ano, kupita patsogolo kwazinthu kwalola opanga kupanga mababu a LED omwe amafanana ndi mawonekedwe ndi kukula kwa mababu achikhalidwe.Mosasamala kanthu za mapangidwe a kutentha kwa kutentha, zinthu zonse za LED zomwe zapeza ENERGY STAR zayesedwa kuti zitsimikizire kuti zimayendetsa bwino kutentha kotero kuti kuwalako kumasungidwa bwino kumapeto kwa moyo wake wovotera.
Kodi kuyatsa kwa LED kumasiyana bwanji ndi magetsi ena, monga incandescent ndi Compact Fluorescent (CFL)?
Kuwala kwa LED kumasiyana ndi incandescent ndi fulorosenti m'njira zingapo.Mukapangidwa bwino, kuyatsa kwa LED kumakhala kogwira mtima, kosunthika, komanso kumatenga nthawi yayitali.
Ma LED ndi magwero a "directional" kuwala, zomwe zikutanthauza kuti amatulutsa kuwala kumalo enaake, mosiyana ndi incandescent ndi CFL, zomwe zimatulutsa kuwala ndi kutentha kumbali zonse.Izi zikutanthauza kuti ma LED amatha kugwiritsa ntchito kuwala ndi mphamvu moyenera pamapulogalamu ambiri.Komabe, zikutanthawuzanso kuti uinjiniya wapamwamba ukufunika kuti apange babu yamagetsi ya LED yomwe imawunikira mbali zonse.
Mitundu yodziwika bwino ya LED imaphatikizapo amber, ofiira, obiriwira, ndi abuluu.Kuti apange kuwala koyera, ma LED amitundu yosiyanasiyana amaphatikizidwa kapena kuphimbidwa ndi zinthu za phosphor zomwe zimatembenuza mtundu wa kuwala kwa kuwala kodziwika bwino "koyera" komwe kumagwiritsidwa ntchito m'nyumba.Phosphor ndi chinthu chachikasu chomwe chimakwirira ma LED ena.Ma LED amitundu amagwiritsidwa ntchito kwambiri ngati magetsi owunikira ndi zowunikira, monga batani lamagetsi pakompyuta.
Mu CFL, mphamvu yamagetsi imayenda pakati pa maelekitirodi kumapeto kulikonse kwa chubu chokhala ndi mpweya.Izi zimatulutsa kuwala ndi kutentha kwa ultraviolet (UV).Kuwala kwa UV kumasinthidwa kukhala kuwala kowoneka bwino kukakhudza zokutira za phosphor mkati mwa babu.
