Inani lokukhishwa kwe-LED liqhubekile nokukhula ukukhanyisa okuphezulu kusengaphambili ama-20% esabelo semakethe imboni yokukhanyisa i-LED igcine ukukhula ngokushesha eminyakeni yamuva. UDing Wenwu, umqondisi woMnyango Wezokwazisa Nge-elekthronikhi woMnyango Wezimboni Nobuchwepheshe Bolwazi, ubikezele ukuthi inani le-LED lasekhaya lizoqhubeka nokugcina ukukhula kwesivinini esingu-20% kuya ku-30% ngonyaka ozayo. Isabelo sivela kakhulu ezizindeni zomphakathi ezifana nezibani ze-civil nezomgwaqo. Ngaphezu kwalokho, uLu Wenbin, isekela lomqondisi we-Resource Society and Environmental Protection Department weKhomishana Yokuthuthukiswa Nezinguquko, ubikezela ukuthi okuhlosiwe kuka-20% wemakethe yezibani ze-LED ngo-2015 kuzofezwa kusenesikhathi. I-Global Efficiency Lighting Forum ixhaswe ngokuhlanganyela yi-United Nations Environment Planning Agency kanye ne-Global Efficiency Lighting Technology Centre, ebiseBeijing izolo (10) e-Beijing. I-UN Environmental Planning Agency iveze ngemakethe yezibani yamazwe angaphezu kwe-150 emhlabeni jikelele ukuthi ugesi okhanyisayo njengamanje udla ngaphezu kuka-15% wokusetshenziswa kukagesi emhlabeni wonke, kanti i-carbon dioxide yenza u-5% womhlaba wonke; kanye nokusetshenziswa kobuchwepheshe bokukhanyisa obuthuthukisiwe obumelwe ama-LED, Kunganciphisa inani lokukhishwa kwe-carbon dioxide kusuka ngaphezu kwesigamu sokukhanya komhlaba wonke, okulingana nakho konke ukukhishwa kwe-Australian. Ngo-2011, izwe lami lakhipha "I-China Graduation of Cantile Lantern Lights", futhi ngo-Okthoba kulo nyaka, kwakunqatshelwe ukuthunyelwa ngaphandle nokuthengisa okungaphezu kuka-60W noma ngaphezulu. Ukukhuthaza imikhiqizo yokukhanyisa esebenza kahle kakhulu, evumela ukusetshenziswa kwamandla okusimeme kanye nokuvikelwa kwemvelo, kodwa futhi kusiza ukwakha iphoyinti elisha lokukhula komnotho. Njengokukhiqizwa komkhiqizo wokukhanyisa omkhulu kunayo yonke emhlabeni, ukusetshenziswa kanye nokuthumela ngaphandle, i-China ikhule ngokushesha embonini yasekhaya ye-LED. Ngo-2013, usayizi wemakethe weqa ama-yuan ayizigidi eziyizinkulungwane ezingama-260. UDing Wenwu uthe inani lomkhiqizo wemboni ye-LED ezweni lami lenyuke ngesilinganiso esingaba ngu-30%. Ukusebenza kahle kokukhanyisa kwedivayisi eyinhloko kuseduze nezinga elijwayelekile lamazwe ngamazwe, futhi uchungechunge lwezimboni luphelele ngokuyisisekelo. Nokho, kukhona izinkinga ezithile ngesikhathi esifanayo. Ngaphezu kobuchwepheshe obuphelele kanye nezinga elithuthukisiwe lamazwe ngamazwe, ukusebenza kwekhwalithi nokuphepha kwezibani yizinkinga eziyinhloko. Ukholelwa ukuthi uma ubambisana ngokuqhubekayo namabhizinisi aphesheya kanye no-R & D izikhungo zokuxazulula ikhwalithi yemibukiso emihle, intengo yemakethe yemikhiqizo yokukhanyisa kwe-LED izokwehliswa ibe uhla olwamukelekayo lwabantu baseShayina eminyakeni emi-3 kuya kwemi-5 ezayo. Ephendula ekuthuthukisweni kwakamuva kwe-EU kwemikhiqizo yezibani ze-LED, u-Ding Wenwu utshele izintatheli ukuthi ukuthuthukiswa kwebhidi i-Huai kuwukuziphatha komhlaba wonke ngokuhamba kwesikhathi, futhi ukubhida kwasekhaya u-Huai nakho kuyathuthuka. Ku-Global Efficiency Lighting Forum izolo (10), uJan Denneman, usihlalo we-Global Lighting Association, uthe ukuguqulwa kwezibani ze-incandescent kuya ekukhanyeni kwe-LED kufana nokuguqulwa kwesignali ye-analog kusignali yedijithali. Ulindele ukuthi ngo-2030, ukukhishwa kwamalambu omhlaba wonke kuzobe kufezeka. Ngonyaka wezi-2015, inani eliphumayo lemakethe yezibani ze-LED ngo-2015 ladlula ama-20% enani lokukhiphayo lika-45 billion weKhomishana Yezomnotho Nolwazi Yesifundazwe sase-Jiangsu, Ikhomishana Yokuthuthukiswa Nezinguquko kanye neminye iminyango eyisithupha. Imibono icacisa imigomo elandelayo yentuthuko: Ngo-2015, isabelo semakethe semikhiqizo yokukhanyisa okusebenzayo kwe-LED esifundazweni safinyelela ngaphezu kuka-20%, futhi inani lokukhipha imboni yokukhanyisa i-LED lifinyelele ku-45 billion yuan. I-150-200 LM/W, umthombo wokukhanya we-LED/umphumela wokukhanya wokukhanyisa ufinyelele ku-130 LM/W; ngo-2020, isabelo semakethe semikhiqizo yokukhanyisa kwe-LED esifundazweni siye sakhula nakakhulu, inani lokukhipha imboni yezibani ze-LED lifinyelele kuma-yuan ayizigidi eziyizinkulungwane ezingu-112, ukusebenza kahle kwedivayisi okukhanyayo kanye nekhwalithi yomkhiqizo wohlelo Lokusebenza Gcina izinga elithuthukile lamazwe ngamazwe. Imibono nezimfuneko wukukhanyiswa kwe-LED kokuqala kwezindawo zomphakathi zezindawo zomphakathi ezikhungweni zikahulumeni, ezezimali noma ukutshalwa kwezimali okukhulu okuphethwe uhulumeni kanye nokwakhiwa. Ukulungiswa kwesitolimende kuqeqebana eqoqweni lezigaba ekupheleni kuka-2016 kuqediwe. Ngenkathi kusetshenziswa inqubomgomo emaphakathi yokusekelwa kwezimali, iziphathimandla ezinekhono zokongiwa kwamandla kuwo wonke amazinga zikhetha ukusekela iqoqo lemiklamo yokubonisa isicelo sokukhanyisa kwe-LED unyaka ngamunye, futhi zikhuthaze ukukhuthazwa nokusebenzisa imikhiqizo yamabhizinisi angumgogodla obalulekile ku-LED. Ukusebenzisa inqubomgomo kahulumeni yokuthengwa kwempahla yemikhiqizo yokonga amandla, izikhungo zikahulumeni kanye nezikhungo zomphakathi zihamba phambili ekwamukeleni imikhiqizo yokukhanyisa kwe-LED. Kumaphrojekthi okutshalwa kwezimali kwempahla engashintshi yokutshalwa kwezimali kwezimali noma kukahulumeni, ukukhanyisa kwe-LED kusetshenziswa njengengxenye ebalulekile yokuhlola nokubuyekeza okonga amandla ephrojekthi.
