Kuunikira kwa LED kwakhala bizinesi yolimbikitsidwa kwambiri ku China chifukwa cha zabwino zake pakuteteza chilengedwe komanso kuteteza mphamvu. Ndondomeko yoletsa mababu a incandescent yakhala ikugwiritsidwa ntchito motsatira malamulo oyenera, zomwe zachititsa kuti zimphona zamakampani zowunikira zipikisane pamakampani a LED. Masiku ano, msika ukukula mofulumira. Ndiye, chitukuko cha zinthu za LED padziko lapansi ndi chiyani?

Malinga ndi kusanthula kwa deta, kugwiritsa ntchito magetsi padziko lonse lapansi kumagwiritsa ntchito 20% ya mphamvu zonse zamagetsi pachaka, zomwe mpaka 90% zimasandulika kukhala mphamvu ya kutentha, zomwe sizikusowa phindu lachuma. Kuchokera pakuwona kutetezedwa kwa mphamvu ndi kuteteza chilengedwe, kuyatsa kwa LED mosakayikira kwakhala ukadaulo wodziwika bwino komanso mafakitale. Pakadali pano, maboma padziko lonse lapansi akukonza malamulo oletsa chilengedwe kuti aletse kugwiritsa ntchito mababu a incandescent. Zimphona zowunikira zachikhalidwe zikubweretsa magwero atsopano a kuwala kwa LED, kufulumizitsa kupanga mitundu yatsopano yamabizinesi. Kulimbikitsidwa ndi zokonda ziwiri za msika ndi malamulo, LED ikukula mwachangu padziko lonse lapansi.

Ubwino wa LED ndi wochuluka, wowoneka bwino kwambiri komanso moyo wautali. Kuwala kwake kumatha kuwirikiza nthawi 2.5 kuposa nyali za fulorosenti ndi kuwirikiza ka 13 kuposa nyali zoyaka. Kuwala kowala kwa nyali za incandescent ndizochepa kwambiri, 5% yokha ya mphamvu yamagetsi imasinthidwa kukhala mphamvu yowunikira, ndipo 95% ya mphamvu yamagetsi imasinthidwa kukhala mphamvu ya kutentha. Nyali za fulorosenti zimakhala zabwinoko kuposa nyali za incandescent, chifukwa zimatembenuza 20% mpaka 25% ya mphamvu yamagetsi kukhala mphamvu yowunikira, komanso kuwononga 75% mpaka 80% ya mphamvu zamagetsi. Chifukwa chake, potengera mphamvu zamagetsi, magetsi onse awiriwa ndi akale kwambiri.

Ubwino wopangidwa ndi kuyatsa kwa LED ndiwosawerengekanso. Akuti Australia inali dziko loyamba padziko lonse lapansi kukhazikitsa malamulo oletsa kugwiritsa ntchito mababu a incandescent mu 2007, ndipo European Union inaperekanso malamulo oletsa mababu a incandescent mu March 2009. Choncho, makampani awiri akuluakulu ounikira miyambo, Osram. ndi Philips, apititsa patsogolo masanjidwe awo pankhani ya kuyatsa kwa LED m'zaka zaposachedwa. Kulowa kwawo kwalimbikitsa kukula kofulumira kwa msika wounikira wa LED komanso kumathandizira kupita patsogolo kwaukadaulo wapadziko lonse wa LED.

Ngakhale makampani a LED akukula bwino pankhani ya kuyatsa, chodabwitsa cha homogenization chikuwonekera kwambiri, ndipo n'zosatheka kupanga mapangidwe osiyanasiyana. Pokhapokha pokwaniritsa izi tingathe kuima nji mumakampani a LED.
