Txhais LED teeb pom kev zoo Technology Los ntawm Chip Level

Niaj hnub no, nrog kev txhim kho txuas ntxiv ntawm LED teeb pom kev zoo thev naus laus zis thiab qhov tseem ceeb ntawm kev teeb meem hluav taws xob hauv zej zog, LED teeb pom kev lag luam tau nce mus rau lub sijhawm tawg tag, nyiam ntau cov nyiaj txiag thiab kev lag luam. Los ntawm qhov kev xav ntawm kev txhim kho ntawm LED teeb pom kev lag luam, los ntawm peb yam, ib qho yog qib nti, lwm qhov yog qib ntim, thiab lwm yam yog qib kev thov. Cov qib nti feem ntau tsom rau cov thev naus laus zis ntawm LED; cov qib pob yog tsuas yog hloov cov chips LED rau hauv lub teeb lossis lub teeb ci uas tuaj yeem siv rau lub teeb; Kev tsim kho thiab siv, kev txhim kho thiab txhim kho ib puag ncig teeb pom kev zoo ntsuas tshuab. Nyob rau theem nti, lub zog tsav tsheb rau kev txhim kho ntawm LED nti tshuab yog ib txwm ua raws li kev ua haujlwm ntawm lub teeb pom kev zoo. Kev teeb tsa thev naus laus zis yog ib qho ntawm cov thev naus laus zis tseem ceeb uas tam sim no tau txais high-efficiency high-power LED chips. Sapphire nyob rau hauv cov khoom siv substrate thiab cov txheej txheem laser hauv ob sab phlu (LLO) thiab cov cuab yeej tshiab keyhered ntawm cov qauv ntsug txhawb nqa cov qauv ntsug yuav tseem yog. Yeej. Txawm li cas los xij, nyob rau yav tom ntej, cov qauv hlau semiconductor tau txais yuav los txhim kho Ohm kev sib cuag, txhim kho cov khoom siv lead ua kom zoo, txhim kho cov khoom siv hluav taws xob thiab hluav taws xob txhaj tshuaj. Kev ua tau zoo, tag nrho kev ua haujlwm ntawm lub teeb dawb LED tuaj yeem ncav cuag 52%. Nrog rau kev txhim kho ntawm LED teeb pom kev zoo, ntawm ib sab, cov nti tau txais me me thiab me me, thiab cov chips uas tuaj yeem txiav ntawm ib qho me me yog ntau dua, yog li txo tus nqi ntawm ib nti. Ntawm qhov tod tes Yog tias tam sim no yog 3W, nws yuav tsim nyob rau hauv 5W thiab 10W yav tom ntej. Qhov no tuaj yeem txo tus naj npawb ntawm cov chips thiab txo tus nqi ntawm daim ntawv thov system ntawm tus nqi ntawm cov teeb pom kev zoo. Nyob rau hauv luv luv, txoj kev inverted, high voltage, thiab silicon puag nitride yuav tseem yog txoj kev loj hlob ntawm semiconductor teeb pom kev zoo nti.
