Kev txhais lus ntawm peb theem ntawm LED teeb pom kev zoo technology: nti, ntim, thiab daim ntawv thov
Nrog rau kev txhim kho txuas ntxiv ntawm LED teeb pom kev zoo thev naus laus zis thiab cov zej zog' kev mloog zoo rau lub zog hluav taws xob, LED teeb pom kev lag luam tau nce mus rau lub sijhawm muaj kev sib kis tag nrho, nyiam cov nyiaj ntau thiab cov lag luam nkag mus. , thiab yog li kev sib tw hauv kev lag luam teeb pom kev zoo tau dhau los ua nruj heev.
Los ntawm qhov kev xav ntawm kev txhim kho ntawm LED teeb pom kev lag luam, nws tuaj yeem hais 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 kev tsim technology ntawm LEDs; cov ntim ntim feem ntau tsom rau kev hloov cov chips LED rau hauv cov teeb hlaws lossis cov teeb pom kev zoo uas tuaj yeem siv rau teeb pom kev zoo; kev txhim kho thev naus laus zis ntawm qib LED daim ntawv thov yog qhov nyuaj, feem ntau suav nrog kev txhim kho kev tswj hwm hluav taws xob thiab kev tsim cov khoom siv tshiab. Kev tsim kho thiab siv, kev tsim kho thiab txhim kho ib puag ncig teeb pom kev zoo ntsuas tshuab.
Chip qib
Kev nrhiav kev ua haujlwm siab luminous tau ua lub zog tsav rau kev txhim kho ntawm LED nti thev naus laus zis. Flip-chip thev naus laus zis tam sim no yog ib qho ntawm cov thev naus laus zis tseem ceeb kom tau txais kev ua haujlwm siab thiab muaj zog LED chips. Cov khoom siv sapphire substrate thiab cov qauv ntsug laser substrate lift-off (LLO) thev naus laus zis (LLO) thiab cov cuab yeej sib txuas tshiab tseem yuav nyob rau lub sijhawm ntev. Yeej.
Txawm li cas los xij, nyob rau yav tom ntej, kev siv cov txheej txheem hlau semiconductor los txhim kho ohmic kev sib cuag, txhim kho cov khoom siv lead ua kom zoo, txhim kho electron txav thiab hluav taws xob txhaj tshuaj, thiab txhim kho qhov kev tshem tawm ntawm lub teeb los ntawm roughening ntawm qhov chaw ntawm LED nti thiab photonic muaju, High reflectivity iav, thiab pob tshab electrodes. Kev ua tau zoo, tag nrho cov txiaj ntsig ntawm cov LEDs dawb tuaj yeem ncav cuag 52% thaum lub sijhawm ntawd.
Nrog rau kev txhim kho ntawm LED teeb pom kev zoo, ntawm ib sab, cov chips tau txais me me thiab me me, thiab cov chips uas tuaj yeem txiav rau qee qhov loj me epitaxial wafer yog nce, yog li txo tus nqi ntawm ib nti. Ntawm qhov tod tes, lub hwj chim ntawm ib lub nti tau loj dua thiab loj dua. , Yog tias nws yog 3W tam sim no, nws yuav txhim kho mus rau 5W thiab 10W yav tom ntej. Qhov no tuaj yeem txo tus naj npawb ntawm cov chips siv rau kev siv teeb pom kev zoo nrog lub zog xav tau thiab txo tus nqi ntawm daim ntawv thov.
Nyob rau hauv luv luv, flip nti, high voltage, silicon-raws li gallium nitride yuav tseem yog txoj kev loj hlob ntawm semiconductor teeb pom kev zoo chips.
Pob qib
Chip-scale ntim, LED filament ntim, siab xim rendering Performance index thiab dav xim gamut yuav yog txoj kev loj hlob qauv ntawm ntim tshuab yav tom ntej. Kev siv cov zaj duab xis pob tshab, txheej txheej roughening technology, thiab DBR reflector technology los txhim kho lub teeb pom kev zoo ntawm LED teeb hlaws tseem yog cov thev naus laus zis tseem ceeb; Nyob rau tib lub sijhawm, COB / COF thev naus laus zis ntawm flip-chip qauv kuj tseem yog lub hom phiaj ntawm cov tuam txhab ntim khoom, kev sib koom ua ke ntawm lub teeb lub cav yuav dhau los ua qhov tseem ceeb ntawm kev tshawb fawb thiab kev loj hlob hauv peb lub hlis tom ntej.
Cov kev daws teeb meem hluav taws xob tshem tawm (high-voltage LEDs), qhov nrov ntawm COB / COF daim ntawv thov: Tsav los ntawm cov nqi tsim nyog, cov kev daws teeb meem hluav taws xob tau maj mam dhau los ua cov khoom siv tau, thiab cov high-voltage LEDs tag nrho cov kev daws teeb meem hluav taws xob tshem tawm, tab sis dab tsi lawv yuav tsum tau daws yog chip kev ntseeg tau. Nrog rau qhov zoo ntawm cov thermal tsis kam, zoo lub teeb profile, tsis muaj soldering, thiab tus nqi qis, COB daim ntaub ntawv yuav nrov nrov nyob rau yav tom ntej.
Tsis tas li ntawd, lub zog nruab nrab yuav dhau los ua txoj kev ntim khoom loj. Tam sim no, feem ntau ntawm cov khoom lag luam hauv kev lag luam yog cov khoom siv hluav taws xob muaj zog LED lossis cov khoom siv hluav taws xob tsawg. Txawm tias lawv muaj lawv tus kheej zoo, lawv kuj muaj insurmountable shortcomings. Lub zog nruab nrab uas sib xyaw ua ke qhov zoo ntawm ob qho khoom siv LED tau los ua.
Kuj tseem muaj kev siv cov ntaub ntawv tshiab hauv kev ntim khoom. Cov ntaub ntawv uas muaj kev tiv thaiv ib puag ncig siab dua xws li kub tsis kam, UV tsis kam thiab tsis muaj dej nqus, xws li cov khoom siv thermosetting EMC, thermoplastic PCT, hloov kho PPA, thiab cov yas zoo li ceramic yuav siv dav.
Rau lub teeb pom kev zoo, rau sab hauv tsev teeb pom kev zoo, LED xim rendering Performance index CRI yog 80 raws li tus qauv thiab 90+ raws li lub hom phiaj. Sim ua kom lub teeb xim ntawm cov khoom siv teeb pom kev zoo nyob ze ntawm Planck nkhaus, txhawm rau txhim kho lub teeb pom kev zoo ntawm LEDs. Nyob rau hauv lub neej yav tom ntej, sab hauv tsev teeb pom kev zoo teeb pom kev zoo kuj yuav them sai sai rau qhov zoo ntawm lub teeb.
Los ntawm kev ua kom zoo ntawm LED ntim tshuab, lub teeb pom kev zoo tau raug txhim kho ntxiv, thiab tam sim no nws tau tshaj 200lm / W, uas yog ntau dua li lwm cov teeb pom kev zoo uas siv ntau ntau. Kev ua haujlwm kub ntawm lub teeb ci ntawm LED teeb hlaws yuav raug txhim kho ntxiv, kev ntseeg siab yuav raug txhim kho ntxiv, thiab lub neej ntawm lub teeb hlaws yuav txuas ntxiv mus, yog li lub teeb xim zoo yuav zoo dua, thiab thaum kawg tib neeg lub qhov muag kev nplij siab. yuav txhim kho ntxiv.
LED daim ntawv thov kev tshawb fawb thiab kev txhim kho qib
Tam sim no, daim ntawv thov cov tuam txhab feem ntau siv cov khoom siv hluav taws xob tshiab, kev tsim kho qhov muag thiab cov khoom siv kho qhov muag tshiab los txhim kho tus nqi ntawm cov khoom siv teeb pom kev zoo thaum ua kom cov khoom ua tau zoo.
Tab sis yav tom ntej, LED teeb pom kev lag luam daim ntawv thov yuav tsom rau cov ntsiab lus no:
1. Interchangeable LED lub teeb cav tshuab raws li daim ntawv thov scenario yuav tsum tau;
2. LED ntse teeb pom kev zoo system architecture tshuab raws li Internet ntawm Yam platform;
3. Kev txhim kho cov teeb pom kev zoo ntawm LED teeb pom kev zoo raws li kev ntseeg tau tsim, thiab kev txhim kho cov teeb pom kev zoo ntawm LED teeb pom kev zoo uas tswj cov xim / ci ci sib xws thaum lub neej voj voog;
4. Kev txhim kho ntawm cov teeb ci raws li qhov loj ntawm thaj chaw ua haujlwm siab diffuser tshuab;
5. Teeb pom kev zoo daws teeb meem thev naus laus zis thiab kev pabcuam rau kev ua haujlwm hauv online teeb pom kev zoo;
6. Cov yam ntxwv xim nplua nuj ntawm LED teeb pom kev zoo ua rau lub teeb pom kev zoo kuj yog qhov tseem ceeb ntawm kev sib tw ntawm LED teeb pom kev zoo.
Cov khoom siv teeb pom kev zoo yog tsim los ntawm cov duab thiab qhov loj ntawm lub teeb ci, thiab qhov loj me yog tsau.
