Ukukhanyisa kwe-LED kuye kwaba lishishini elikhuthazwa ngamandla e-China ngenxa yeenzuzo zalo zokukhuselwa kwendalo kunye nokugcinwa kwamandla. Umgaqo-nkqubo wokuvinjelwa kwee-incandescent bulbs uphunyezwe ngokuhambelana nemimiselo echaphazelekayo, eye yabangela ukuba ii-giants zoshishino zokukhanyisa eziqhelekileyo zikhuphisane kwishishini le-LED. Namhlanje, imarike ikhula ngokukhawuleza. Ngoko ke, yintoni imeko yophuhliso lweemveliso ze-LED kwihlabathi?

Ngokutsho kohlalutyo lwedatha, ukusetyenziswa kombane wokukhanya kwehlabathi jikelele kwi-akhawunti ye-20% yokusetyenziswa kombane ngonyaka, apho ukuya kuthi ga kwi-90% iguqulelwe kusetyenziso lwamandla obushushu, okungekho nje ukusilela kwezoqoqosho. Ngokombono wogcino lwamandla kunye nokukhuselwa kwendalo, ukukhanya kwe-LED ngokungathandabuzekiyo kuye kwaba bubuchwephesha obubonwa kakhulu kunye noshishino. Okwangoku, oorhulumente behlabathi jikelele baqulunqa ngokusebenzayo imimiselo yokusingqongileyo ukuthintela ukusetyenziswa kwezibane ze-incandescent. Iingxilimbela zokukhanyisa zendabuko zizisa imithombo emitsha yokukhanya kwe-LED, ukukhawuleza ukuqulunqwa kweemodeli ezintsha zoshishino. Ikhuthazwa yimidla emibini yeemarike kunye nemimiselo, i-LED ikhula ngokukhawuleza kwihlabathi jikelele.

Izibonelelo ze-LED zininzi, kunye nokusebenza okukhanyayo okuphezulu kunye nobomi obude. Ukukhanya kwayo kunokufikelela izihlandlo ezi-2,5 kunezibane zefluorescent nezihlandlo ezili-13 zokukhanyisa izibane. Ukusebenza okukhanyayo kwezibane ze-incandescent kuphantsi kakhulu, kuphela i-5% yamandla ombane iguqulwa ibe amandla okukhanya, kwaye i-95% yamandla ombane iguqulwa ibe amandla okushisa. Izibane zeFluorescent zibhetele noko kunezibane ze-incandescent, njengoko ziguqula i-20% ukuya kwi-25% yamandla ombane kumandla ombane, kodwa zikwamosha i-75% ukuya kwi-80% yamandla ombane. Ngoko ke ngokombono wokonga amandla, yomibini le mithombo yokukhanya iphelelwe lixesha.

Izibonelelo eziveliswa kukukhanya kwe-LED nazo azinakubalwa. Kuxelwa ukuba iOstreliya yaba lilizwe lokuqala ehlabathini ukwazisa imimiselo ethintela ukusetyenziswa kwebhalbhu ze-incandescent ngo-2007, kwaye i-European Union nayo yapasisa imimiselo yokuphelisa ii-incandescent bulbs ngo-Matshi 2009. Ngoko ke, iinkampani ezimbini ezinkulu zokukhanyisa zendabuko, i-Osram kunye nePhilips, baye bakhawulezisa ukubekwa kwabo kwintsimi yokukhanyisa kwe-LED kwiminyaka yamuva. Ukungena kwabo kukhuthaze uphuhliso olukhawulezayo lwemakethi yokukhanya kwe-LED kwaye kwanyusa isantya senkqubela phambili yetekhnoloji ye-LED yehlabathi.

Nangona imboni ye-LED ikhula kakuhle kwintsimi yokukhanyisa, i-phenomenon ye-homogenization iya ikhula ngokubonakalayo, kwaye akunakwenzeka ukwenza iindlela ezahlukeneyo zoyilo. Kuphela ngokufezekisa oku sinokuma siqinile kwishishini le-LED.
