Nawa maubwino aukadaulo wowunikira kuwala kwa diode. Tikukhulupirira kuti izi zingakuthandizeni kudziwa zambiri za kuyatsa kwa LED.

1. Kuwala kwa LED nthawi yayitali:

Mosavuta mwayi wofunikira kwambiri wa ma LED poyerekeza ndi kuyatsa kwachikhalidwe ndi kutalika kwa moyo. Ma LED ambiri amatha maola ogwirira ntchito 50,000 mpaka maola 100,000 ogwirira ntchito kapena kupitilira apo. Izi ndi nthawi 2-4 utali wa fulorosenti ambiri, zitsulo halide, ndipo ngakhale sodium nthunzi magetsi. Ndi nthawi yoposa 40 kutalika kwa babu wamba wa incandescent.

2. Mphamvu Zamagetsi za LED:

Ma LED nthawi zambiri amagwiritsa ntchito mphamvu zochepa kwambiri. Ziwerengero zomwe muyenera kuziyang'ana poyerekeza mphamvu zamagetsi zowunikira zosiyanasiyana zimatchedwa ndi limodzi mwamawu awiri: kuwala kowala kapena ma lumens othandiza. Zinthu ziwirizi zimalongosola kuchuluka kwa kuwala komwe kumatulutsa pagawo lililonse la mphamvu (watts) yomwe bulb imadyedwa. Malinga ndi kafukufuku, ntchito zambiri zowunikira zowunikira za LED zimabweretsa kusintha kwa 60-75%. Kutengera magetsi omwe alipo komanso ma LED omwe adayikidwa, ndalama zitha kupitilira 90%.

3. Kupititsa patsogolo Chitetezo chokhala ndi ma LED:

Chitetezo mwina ndiye mwayi womwe nthawi zambiri umanyalanyazidwa pankhani ya kuyatsa kwa LED. Chowopsa choyamba pankhani yowunikira ndi kutulutsa kwa kutentha. Ma LED amatulutsa pafupifupi kutentha kwapatsogolo pomwe mababu achikhalidwe ngati zoyatsira moto amasintha mphamvu yopitilira 90% ya mphamvu zonse zomwe zimagwiritsidwa ntchito kupangira kutentha. Izi zikutanthauza kuti 10% yokha ya magetsi opangira mphamvu zamagetsi amagwiritsidwa ntchito powunikira.

Kuphatikiza apo, chifukwa ma LED amagwiritsa ntchito mphamvu zochepa amatha kugwira ntchito bwino pamakina amagetsi otsika kwambiri. Izi nthawi zambiri zimakhala zotetezeka ngati chinachake chalakwika.

4. Kuwala kwa LED Ndikochepa Mwakuthupi:

Chipangizo chenicheni cha LED ndi chaching'ono kwambiri. Zida zazing'ono zamagetsi zimatha kukhala zosakwana gawo limodzi mwa magawo khumi a mm imodzi²pomwe zida zazikulu zamagetsi zimatha kukhala zazing'ono ngati mm². Kukula kwawo kwakung'ono kumapangitsa ma LED kuti azitha kusinthika ndi kuchuluka kosawerengeka kwa ntchito zowunikira. Kugwiritsiridwa ntchito kosiyanasiyana kwa ma LED kumaphatikizapo mawonekedwe osiyanasiyana kuchokera ku mizu yawo mu kuyatsa kwa board board ndi zizindikiro zamagalimoto mpaka kuunikira kwamakono, nyumba zogona, ntchito zamalonda, ndi zina zotero.

5. Ma LED Ali ndi Mlozera Waukulu Wopereka Mtundu (CRI):

CRI, muyeso wa mphamvu ya kuwala kuwulula mtundu weniweni wa zinthu poyerekeza ndi kuwala koyenera (kuwala kwachilengedwe). Kawirikawiri, CRI yapamwamba ndi khalidwe lofunika. Ma LED nthawi zambiri amakhala ndi mavoti apamwamba kwambiri akafika ku CRI.

Mwina imodzi mwa njira zabwino kwambiri zoyamikirira CRI ndikuyang'ana kufananitsa kwachindunji pakati pa kuyatsa kwa LED ndi njira yowunikira yachikhalidwe ngati nyali za nthunzi za sodium. Onani chithunzi chotsatirachi kuti mufananize ndi kusiyanitsa zochitika ziwirizi:

Mitundu yamitundu yomwe ingatheke pamagetsi osiyanasiyana a LED nthawi zambiri imakhala pakati pa 65 ndi 95 zomwe zimawonedwa kuti ndizabwino kwambiri.
