Nazi ubwino wa ukadaulo wowunikira ma diode. Tikukhulupirira kuti izi zingakuthandizeni kudziwa zambiri za kuwala kwa LED.

1. Moyo wa Kuwala kwa LED:

Ubwino waukulu kwambiri wa ma LED poyerekeza ndi njira zowunikira zachikhalidwe ndi moyo wautali. Ma LED apakati amakhala ndi maola 50,000 ogwira ntchito mpaka maola 100,000 ogwira ntchito kapena kuposerapo. Utali wake ndi nthawi ziwiri kapena kanayi kuposa magetsi ambiri a fluorescent, metal halide, komanso sodium vapor. Ndi nthawi yoposa nthawi 40 kuposa babu wamba wa incandescent.

2. Kugwiritsa Ntchito Mphamvu za LED:

Ma LED nthawi zambiri amagwiritsa ntchito mphamvu zochepa kwambiri. Ziwerengero zoti muziyang'ana poyerekeza mphamvu ya magetsi osiyanasiyana zimatchedwa ndi mawu awiri: mphamvu yowala kapena ma lumens othandiza. Zinthu ziwirizi zimafotokoza kuchuluka kwa kuwala komwe kumachokera pa unit ya mphamvu (watts) yomwe babu limagwiritsa ntchito. Malinga ndi kafukufuku, mapulojekiti ambiri okonzanso magetsi a LED amachititsa kuti mphamvu zonse za magetsi ziwonjezeke ndi 60-75%. Kutengera magetsi omwe alipo ndi ma LED enaake omwe adayikidwa, ndalama zomwe zingasungidwe zitha kukhala zoposa 90%.

3. Chitetezo Chokwera ndi Ma LED:

Chitetezo mwina ndi ubwino womwe nthawi zambiri umanyalanyazidwa pankhani ya magetsi a LED. Choopsa chachikulu pankhani ya magetsi ndi kutentha komwe kumatulutsa. Ma LED samatulutsa kutentha kulikonse pomwe mababu achikhalidwe monga ma incandescent amasintha mphamvu yoposa 90% ya mphamvu yonse yomwe imagwiritsidwa ntchito kuwayatsa mwachindunji kutentha. Izi zikutanthauza kuti 10% yokha ya mphamvu zomwe zimayatsa magetsi a incandescent ndi yomwe imagwiritsidwa ntchito makamaka pa kuwala.

Kuphatikiza apo, chifukwa ma LED amagwiritsa ntchito mphamvu zochepa amatha kugwira ntchito bwino pamagetsi otsika mphamvu. Izi nthawi zambiri zimakhala zotetezeka kwambiri ngati china chake chalakwika.

4. Ma LED ndi Ang'onoang'ono:

Chipangizo chenicheni cha LED ndi chaching'ono kwambiri. Zipangizo zamagetsi zazing'ono zimatha kukhala zosakwana gawo limodzi mwa magawo khumi a mm imodzi.²pomwe zida zazikulu zamagetsi zimatha kukhala zazing'ono ngati mm²Kukula kwawo kochepa kumapangitsa ma LED kukhala osinthika kwambiri ku ntchito zambirimbiri zowunikira. Ntchito zosiyanasiyana za ma LED zimaphatikizapo mitundu yosiyanasiyana kuyambira mizu yawo mu magetsi a circuit board ndi zizindikiro za magalimoto mpaka magetsi amakono, nyumba, malo ogulitsa, ndi zina zotero.

5. Ma LED Ali ndi Chizindikiro Chabwino Chojambulira Mitundu (CRI):

CRI, muyeso wa mphamvu ya kuwala powulula mtundu weniweni wa zinthu poyerekeza ndi gwero loyenera la kuwala (kuwala kwachilengedwe). Kawirikawiri, CRI yapamwamba ndi khalidwe lofunika kwambiri. Ma LED nthawi zambiri amakhala ndi mavoti apamwamba kwambiri pankhani ya CRI.

Mwina njira imodzi yabwino kwambiri yodziwira CRI ndikuyang'ana kufananiza mwachindunji pakati pa kuyatsa kwa LED ndi njira yowunikira yachikhalidwe monga nyali za sodium vapor. Onani chithunzi chotsatirachi kuti muyerekeze ndikusiyanitsa zitsanzo ziwirizi:

Mitundu ya ma LED omwe angagwiritsidwe ntchito pa magetsi osiyanasiyana nthawi zambiri amakhala pakati pa 65 ndi 95 zomwe zimaonedwa kuti ndi zabwino kwambiri.
