Ka 2006, CREE e phatlalalitse ho hlahisoa ha LED e tšoeu e pholileng, "XP.G”, e behang lirekoto tse ncha ka katleho e khanyang le khanya.Ha motlakase o le 350 mA, khanya ea eona e khanyang e fihla ho 139 lm, 'me katleho e khanyang ke 1 ho lm/W.Khanya le bokhabane bo khanyang ka ho latellana li 37% le 53% li phahame ho feta XR e khanyang ea Cree.ELED, e bitsoang "LED ea indasteri e khanyang le e sebetsang hantle haholo".
Ka 2007, Nichia o ile a lokolla mofuta o mocha oa LED.Sehlahisoa sa liteko se na le phallo e khanyang ea ho fihla ho 145 m tlasa boemo ba hona joale ba 350 mA, bokhoni bo khanyang bo ka bang 134 lm/w, boholo ba chip ea 1 m.㎡, le mocheso oa 'mala oa 4 988K (tabeng ea Ir = 20 mA) , Ts'ebetso e khanyang e phahame ho feta 1 69 lm / W).
Ka 2007, k'hamphani ea CREE ea Amerika e ile ea holisa heterojunction e habeli holim'a substrate ea SIC, mme lisebelisoa tse hlahisitsoeng le tsona li ne li le ntle haholo.SiC substrate e ka etsa electrode ea tšepe ea LED e thehiloeng ho Gabl karolong e ka tlaase ea substrate, 'me ea hona joale e ka phalla ka mokhoa o otlolohileng ka har'a substrate e fokolang ea ho hanyetsa, e leng eona e behang motheo oa nts'etsopele ea lisebelisoa tse ling tsa optoelectronic.
Selemong sona seo, Nichia o ile a lokolla moloko o latelang oa li-LED tse tšoeu tse matla.Phallo e khanyang ea 350 mA hona joale ke 145lm, 'me katleho e khanyang ke 134lm/W.Lebaka la ts'ebetso e phahameng ea LED e tšoeu ke ho hlokomela ts'ebetso e phahameng ea chip e putsoa ea LED e sebelisitsoeng.Ha LED e putsoa e tsamaisoa ho 350 mA, matla a optical ke 651mW, wavelength ke 444nm, katleho ea ka ntle ea quantum ke 66.5%, 'me WPE ke 60.3%.
Selemong sona seo, Nichia o ile a etsa tlhahiso ea li-LED tse tšoeu tse nang le khanya e khanyang ea 150 lm/W.Ho sebetsa hantle ha LED ena ho emetse boemo bo holimo indastering ka nako eo, mme mofuta o nang le matla a pele a 20 mA ke 1001m/W.
Mathoasong a 2009, CREE e phatlalalitse hore e fihletse phello e khanyang ea 161 lm / W le mocheso oa 'mala oa 4 689K.Maemo a tloaelehileng a tlhahlobo ea LED ena a etsoa ka mocheso oa kamore le koloi ea hona joale ea 350 mA.
Qetellong ea 2009, CREE e phatlalalitse hore khanya ea eona e tšoeu ea matla a phahameng a LED e fihletse 1 86 lm/W.Liphetho tsa liteko tsa CREE li bonts'a hore ha mocheso oa 'mala o amanang o le 4577K, LED e ka hlahisa khanya ea 1971m.Teko e etsoa sebakeng se tloaelehileng sa teko se nang le koloi ea hona joale ea 350 mA mocheso oa kamore.
Mathoasong a 2009, ho latela liphetho tsa laboratori ea Nichia, katleho e khanyang ea LED e ile ea eketseha ho fihlela ho 2491 W ho hanyetsa ho 20 mA.Leha ho le joalo, tabeng ea 350 mA hona joale e sebelisoang hangata indastering ea LED, katleho e khanyang e theohile ho 1451 ho mamella W, e leng se tsositseng tlhokomelo ea indasteri.
Ka 2011, lienjiniere tsa Osram's R&D li ile tsa ntlafatsa ka botlalo mahlale ohle a amanang le tlhahiso ea LED.Litekong tsa laboratori, li-LED tse tšoeu tse sa tsoa ntlafatsoa li behile khanya ea k'hamphani le lirekoto tse sebetsang hantle.Tlas'a boemo bo tloaelehileng ba ho sebetsa hona joale ba 350 mA, khanya ea LED e ka fihla ho 1 55 lm, 'me katleho e khanyang e ka holimo ho 1 36 lm / w.Mohlala o mosoeu oa leseli la LED o sebelisa 1 m㎡chip, mocheso oa 'mala oa leseli le hlahisitsoeng ke 5000K,' me khokahanyo ea chromaticity ke 0.349/0.393 (cx/cy).
Ka 2011, CREE e phatlalalitse hore khanya ea eona e tšoeu ea LED e feta 231lm/W.Khamphani e sebelisitse karolo ea mojule o le mong, mme e lekanya katleho e khanyang ea LED e tšoeu ea 23llm/W ka mocheso oa 'mala oa 450OK le mocheso o tloaelehileng oa kamore ea teko ea 350mA.Hajoale, matšoao a fapaneng a LED a ntse a le nts'etsopele e tsoelang pele.Ka ho atolosoa ha masimo a kopo, litlhoko tsa mabone a lebone la LED li fetoha butle-butle.
