Tarihin ci gaba na hasken hasken LED da ingantaccen haske

A cikin 2006, CREE ta sanar da ƙaddamar da sabon farin LED mai sanyi, “XP.G”, wanda ke saita sabbin bayanai cikin ingantaccen inganci da haske.Lokacin tuƙi na yanzu shine 350mA, hasken sa ya kai 139 lm, kuma ingantaccen ingancin shine 1 zuwa lm/W.Hasken haske da ingantaccen haske sune 37% da 53% sama da mafi kyawun Cree XR.ELED, wanda ake kira "fitilar hasken wutar lantarki na masana'antu".

A cikin 2007, Nichia ta fito da sabon nau'in LED.Samfurin gwaji yana da haske mai haske har zuwa 145 m a ƙarƙashin yanayin halin yanzu na 350 mA, ingantaccen haske na kusan 134 lm / w, guntu girman 1 m㎡, da zazzabi mai launi na 4 988K (a cikin yanayin Ir = 20 mA) , Ƙarfin haske yana da girma kamar 1 69 lm / W).

A cikin 2007, kamfanin CREE na Amurka ya haɓaka heterojunction sau biyu akan siginar SIC, kuma na'urorin da aka samar suma suna da kyau.Ƙarfe na SiC na iya ƙirƙira na'urar lantarki na ƙarfe na LED na tushen Gabl a kasan substrate, kuma halin yanzu yana iya gudana a tsaye ta hanyar ƙananan juriya mai mahimmanci, wanda kuma ya kafa harsashin haɓakar wasu na'urorin optoelectronic.

A cikin wannan shekarar, Nichia ta fito da ƙarni na gaba na manyan LEDs masu ƙarfi.Juyin haske na shigarwar 350mA na yanzu shine 145lm, kuma ingantaccen haske shine 134lm/W.Dalilin babban ingancin farin LED shine fahimtar babban ingancin guntu mai shuɗi na LED da aka yi amfani da shi.Lokacin da aka yi amfani da blue LED a 350 mA, ikon gani shine 651mW, tsawon tsayin shine 444nm, ƙimar ƙimar waje shine 66.5%, kuma WPE shine 60.3%.

A cikin wannan shekarar, Nichia ya sanya cikin samar da fararen LEDs tare da ingantaccen haske na 150 lm / W.Ingancin wannan LED yana wakiltar matsayi mafi girma a cikin masana'antar a wancan lokacin, kuma nau'in da ke da ƙarfin halin yanzu na 20 mA shine 1001m/W.

A farkon 2009, CREE ta sanar da cewa ta sami sakamako mai haske na 161 lm/W da zafin launi na 4 689K.Madaidaicin yanayin gwaji na wannan LED ana aiwatar da shi a cikin ɗaki da zafin jiki da motsi na yanzu na 350mA.

A ƙarshen 2009, CREE ta ba da sanarwar cewa ingantaccen haske mai ƙarfi na LED mai haske ya sami nasarar 1 86 lm / W.Sakamakon gwajin CREE ya nuna cewa lokacin da yanayin zafin launi mai alaƙa ya kasance 4577K, LED na iya samar da fitowar haske na 1971m.Ana yin gwajin a cikin daidaitaccen yanayin gwaji tare da injin tuƙi na 350 mA a zafin jiki.

A farkon 2009, bisa ga sakamakon dakin gwaje-gwaje na Nichia, ingantaccen ingancin LED ya karu zuwa juriya na 2491 W a 20 mA.Duk da haka, a cikin yanayin 350 mA na yanzu da aka saba amfani da shi a cikin masana'antar LED, ingancin haske ya ragu zuwa 1451 tsayayya W, wanda ya tada hankalin masana'antu.

A cikin 2011, injiniyoyin R&D na Osram sun inganta gaba ɗaya duk fasahohin da suka shafi masana'antar LED.A cikin gwaje-gwajen dakin gwaje-gwaje, sabbin fararen ledojin da aka ƙera sun saita haske na kamfanin da bayanan ingancin inganci.A karkashin daidaitaccen yanayin aiki na yanzu na 350 mA, hasken LED zai iya kaiwa 1 55 lm, kuma ingantaccen ingancin ya kai 1 36 lm / w.Farar haske LED samfurin yana amfani da 1 m㎡guntu, zafin launi na hasken da aka fitar shine 5000K, kuma daidaitawar chromaticity shine 0.349/0.393 (cx/cy).

A cikin 2011, CREE ta sanar da cewa ingantaccen hasken LED ɗin sa ya wuce 231lm/W.Kamfanin ya yi amfani da bangaren module guda ɗaya, kuma ya auna farin LED mai haske mai ƙarfi na 23mm/W a zafin launi na 450OK da daidaitaccen ɗakin ɗakin gwaji na 350mA.A halin yanzu, alamun daban-daban na LED har yanzu suna ci gaba da ci gaba.Tare da faɗaɗa filayen aikace-aikacen, abubuwan buƙatun don beads na fitilar LED suna bambanta a hankali.
