Ngo-2006, iCREE yabhengeza ukumiselwa kwe-LED entsha emhlophe epholileyo, “XP.G”, ebeka iirekhodi ezintsha ekusebenzeni okukhanyayo kunye nokuqaqamba.Xa i-drive current yi-350 mA, i-flux yayo ekhanyayo ifikelela kwi-139 lm, kunye nokusebenza okukhanyayo yi-1 ukuya kwi-lm/W.Ukukhanya kunye nokusebenza kakuhle okuqaqambileyo ngokulandelelanayo kukwi-37% kunye ne-53% ephezulu kune-XR eqaqambileyo ye-Cree.I-ELED, ebizwa ngokuba "yi-LED ekhanyayo kunye neyokusebenza okuphezulu kokukhanya kwe-LED".
Ngo-2007, u-Nichia wakhupha uhlobo olutsha lwe-LED.Imveliso yovavanyo inokukhanya okukhanyayo ukuya kuthi ga kwi-145 m phantsi kwemeko yangoku yangoku ye-350 mA, ukukhanya okukhanyayo malunga ne-134 lm / w, ubukhulu be-chip ye-1 m.㎡, kunye nokushisa kombala we-4 988K (kwimeko ye-Ir = 20 mA) , Ukusebenza okukhanyayo kuphezulu njenge-1 69 lm / W).
Kwi-2007, inkampani ye-American CREE yakhula i-heterojunction ephindwe kabini kwi-SIC substrate, kwaye izixhobo eziveliswayo nazo zazihle kakhulu.I-substrate ye-SiC inokwenza i-electrode yensimbi ye-LED esekwe kwi-Gabl ezantsi kwe-substrate, kwaye yangoku inokuhamba ngokuthe nkqo kwi-substrate ephantsi yokumelana ne-conductive, ekwabeka isiseko sophuhliso lwezinye izixhobo ze-optoelectronic.
Ngaloo nyaka, u-Nichia wakhulula isizukulwana esilandelayo se-LED ezimhlophe ezinamandla.Ukukhanya okukhanyayo kwe-350 mA igalelo langoku yi-145lm, kunye nokusebenza okukhanyayo yi-134lm / W.Isizathu sokusebenza okuphezulu kwe-LED emhlophe kukuqonda ukusebenza okuphezulu kwe-chip ye-LED eluhlaza esetyenzisiweyo.Xa i-LED eluhlaza okwesibhakabhaka iqhutywe kwi-350 mA, amandla okukhanya yi-651mW, i-wavelength yi-444nm, i-quantum yangaphandle esebenzayo yi-66.5%, kunye ne-WPE yi-60.3%.
Kwangalo nyaka, u-Nichia wafaka ukuveliswa kwee-LED ezimhlophe kunye nokusebenza kakuhle okukhanyayo kwe-150 lm/W.Ukusebenza kakuhle kwale LED kubonisa izinga eliphezulu kwishishini ngelo xesha, kwaye uhlobo oluhamba phambili lwangoku lwe-20 mA yi-1001m / W.
Ekuqaleni kwe-2009, i-CREE yabhengeza ukuba iphumelele ukukhanya kwe-161 lm / W kunye nobushushu bombala we-4 689K.Iimeko zokuvavanya ezisemgangathweni zale LED ziqhutyelwa kwiqondo lokushisa lokushisa kunye ne-drive current ye-350 mA.
Ekupheleni kuka-2009, iCREE yabhengeza ukuba ukukhanya kwayo okumhlophe okunamandla aphezulu e-LED kuphumeze i-1 86 lm/W.Iziphumo zovavanyo lwe-CREE zibonisa ukuba xa ubushushu bombala obuhambelanayo buyi-4577K, i-LED inokuvelisa ukukhanya kwe-1971m.Uvavanyo lwenziwa kwindawo yovavanyo oluqhelekileyo kunye ne-drive current ye-350 mA kwiqondo lokushisa.
Ekuqaleni kuka-2009, ngokweziphumo zebhubhoratri ye-Nichia, ukukhanya okukhanyayo kwe-LED kwandiswe kwi-2491 W ukuxhathisa kwi-20 mA.Nangona kunjalo, kwimeko ye-350 mA yangoku esetyenziswa ngokuqhelekileyo kwishishini le-LED, ukusebenza kakuhle okukhanyayo kuye kwehla ukuya kwi-1451 ukumelana ne-W, okuye kwavusa ingqalelo yoshishino.
Ngo-2011, iinjineli ze-R&D ze-Osram zaphucula ngokupheleleyo zonke iitekhnoloji ezinxulumene nokuveliswa kwe-LED.Kuvavanyo lwaselabhoratri, ii-LED ezimhlophe ezisanda kuphuhliswa zibeka ukuqaqamba kwenkampani kunye neerekhodi eziqaqambileyo.Ngaphantsi kwemeko esemgangathweni yokusebenza kwangoku ye-350 mA, ukukhanya kwe-LED kunokufikelela kwi-1 55 lm, kwaye ukukhanya okukhanyayo kuphezulu njenge-1 36 lm / w.Ukukhanya okumhlophe kweprototype ye-LED isebenzisa i-1 m㎡chip, ubushushu bombala wokukhanya okukhutshiweyo yi-5000K, kwaye ulungelelwaniso lwechromaticity yi-0.349/0.393 (cx/cy).
Ngo-2011, i-CREE yabhengeza ukuba ukukhanya kwayo okumhlophe kwe-LED kungaphezulu kwe-231lm/W.Inkampani isebenzise icandelo lemodyuli enye, kwaye yalinganisa ukukhanya okukhanyayo kwe-LED emhlophe ye-23llm / W kubushushu bombala we-450OK kunye nobushushu obuqhelekileyo begumbi lovavanyo lwe-350mA.Okwangoku, izikhombisi ezahlukeneyo ze-LED zisekuphuhliso oluqhubekayo.Ngokwandiswa kweendawo zokufaka izicelo, iimfuno zezibane zesibane se-LED zihluka ngokuthe ngcembe.
