Japanese LED tshiab tiam sis
Nyiv txoj haujlwm nyiam ntawm LED thev naus laus zis, tshwj tsis yog tias Nichia Chemical siv patents txuas ntxiv lub teeb dawb thiab RGB kev lag luam txhawm rau tswj hwm nws txoj kev tswj hwm. Feem ntau ntawm cov tuam txhab LED hauv Nyij Pooj, tshwj tsis yog kev ua lag luam Nyij Pooj, lawv tsis tau them sai sai rau thiab nrhiav lub teeb dawb. Qhov ci ntsa iab ntawm LEDs tau txhim kho, thiab tam sim no lawv tab tom tsom mus rau yuav ua li cas npaj lub teeb pom kev zoo thiab cov khoom siv sib txawv los ua kom sib sib zog nqus ultraviolet LEDs, tshwj xeeb tshaj yog kev tawg ntawm 265nm thiab 280nm. Qhov nyuaj dua, lawv txaus siab rau kev tshawb fawb thiab ntau lawm. , Tam sim no, UVC cov khoom lag luam ntawm Nichia thiab Nikki tau ua tiav zoo thiab tuaj yeem ua huab hwm coj- tsim tawm, tab sis cov lus hais yog kim heev. Tau kawg, cov txuj ci tseem ceeb ntawm UVC nti yog MOCVD cov cuab yeej. Nichia cov cuab yeej yog tsim thiab npaj rau ntau lawm los ntawm nws tus kheej. Tsis muaj leej twg paub cov ntsiab lus ntawm cov cuab yeej no. Tam sim no, Taiyo Nippon Sanso ntawm Nyiv lub Taiyo Nippon Sanso tau tsim SR-4000 MOCVD cov khoom siv rau cov khoom siv zoo txhuas nitride, uas yog siv dav hauv cov tuam txhab tsim khoom UVC. Tau kawg, chav kuaj ntawm Tokushima University thiab Nitride Semiconductors Co., Ltd. kuj yog rau UVC. tau tsim ib hom tshiab ntawm MOCVD cov cuab yeej, Nyiv yog lub teb chaws uas muaj kev ua haujlwm zoo, thiab nws tsis yog txoj haujlwm nyuaj los sib sau ua ke cov khoom siv hauv Nyij Pooj.
Nyiv txoj kev loj hlob ntawm silicon substrate LEDs. Xyoo 2012, Toshiba tau tshaj tawm qhov siab tshaj -profile tshaj tawm los yuav Preh's yim-inch silicon substrate patent thiab tshaj tawm tias nws yuav loj- ua rau xyoo 2013. Txhua zaus kuv mus rau Nyiv LED -txog kev nthuav qhia nyob rau xyoo tas los no, Kuv tsis tau pom Toshiba yim -inch silicon substrate patent. inch silicon substrate gallium nitride LED? Xws li ib tug loj LED exhibition yuav tsum tau nthuav tawm, tab sis qhov no kuj ua pov thawj tias lawv tsis muaj ntau tshaj li 90 feem pua ntawm cov neeg txawj ntse, thiab lawv yuav tsis cog lus tias lawv yuav muaj cov txuj ci no. Peb Suav txawv, peb tsuas yog yuav tsum tau pom cov cim, txawm tias tsuas yog ib nrab ntawm txoj kev, nws yuav qaug cawv, yog li kuv ntseeg tias silicon tseem muaj txoj hauv kev mus ntev, thiab tej zaum nws tsuas yog siv tau los ua lub teeb pom kev zoo hauv yav tom ntej thiab tsis dhau los ua qhov tseem ceeb.
Txawm li cas los xij, Preh Bridgelux tau koom nrog hauv kev nthuav qhia txhua zaus, tab sis yog tias koj saib sab laug thiab sab xis, koj tsis tuaj yeem pom silicon. Lawv tseem yog sapphire formal chips. Lawv tseem yog lub ntsiab COB lub teeb ci. Ntawm chav kawm, lawv kuj muaj cov chaw taws teeb Phosphor thev naus laus zis. Tej yam no tsuas yog dag xwb. Cov neeg tuaj saib, rau cov neeg sab hauv, tsuas yog luag nyav xwb. Txawm hais tias qhov xwm txheej ntawm New Century Optoelectronics tsis tau zoo nyob rau hauv xyoo tas los no, lawv muaj kev sib sib zog nqus nyob rau hauv Nyiv kev ua lag luam, yog li lawv yuav tshwm sim ntawm kev nthuav qhia txhua xyoo. Nws qhov kev thov rov hais dua yog qhov yooj yim thiab xav tsis thoob, ib qho 50W nti, uas yog tsim rau cov tuam txhab teeb pom kev zoo uas xav hloov kho rau LED Nws yog qhov muaj txiaj ntsig zoo. Nws zoo nkaus li tias lub flip-chip COB thev naus laus zis yuav yog qhov tseem ceeb ntawm qhov chaw teeb pom kev zoo yav tom ntej.
