Ua tiav Luminous Efficacy ntawm>90lm / W hauv ib qho Ultra - Me me Φ60mm Volume
Nyob rau hauv lub realm ntawm teeb pom kev zoo technology, ua kom tiav ib tug siab luminous efficiency nyob rau hauv ib tug compact ntim yog ib tug nyuaj tab sis tseem ceeb heev nrhiav. Qhov kev thov rau siab - teeb pom kev zoo hauv cov ntawv me me -, xws li cov khoom siv nqa tau yooj yim, cov teeb pom kev tshwj xeeb, thiab qee qhov teeb pom kev zoo vaj tsev, tau txhawb cov kws tshawb fawb thiab cov kws tsim khoom los tshawb nrhiav cov kev daws teeb meem tshiab. Ntawm no, peb tham txog cov tswv yim kom ua tiav qhov kev ua tau zoo ntawm ntau dua 90lm / W hauv ib qho ultra - me me Φ60mm ntim.
1. Xaiv High - Efficiency LED Chips
Lub plawv ntawm ib qho kev ua haujlwm siab - lub teeb pom kev zoo yog lub teeb - emitting diode (LED) nti. Advanced LED chips nrog siabInternal quantum efficiency (IQE)yog qhov tseem ceeb. Piv txwv li, qee lub xeev - ntawm - lub - kos duab xiav - emitting LED chips, uas feem ntau yog siv los ua lub hauv paus rau lub teeb ci dawb los ntawm kev hloov pauv phosphor, tuaj yeem muaj IQEs nce mus txog 100%. Cov chips no yog tsim los nrog cov khoom siv semiconductor optimized thiab cov txheej txheem kev loj hlob ntawm epitaxial kom txo qis tsis yog - radiative recombination, kom ntseeg tau tias muaj feem ntau ntawm cov neeg nqa khoom txhaj tshuaj recombine los tsim photons.
Thaum xaiv LED chips rau Φ60mm ntim, chips nrog lub zog siab - tuav peev xwm ntawm ib chav tsev yog nyiam. Cov me me - cov chips me me uas tuaj yeem tso cov cua sov kom zoo thaum ua haujlwm ntawm qhov kub tam sim no tuaj yeem xa tawm ntau lub teeb pom kev zoo. Piv txwv li, qee cov chips nrog micro - nplai tsim, uas txo qhov kev ncua deb rau cov neeg nqa khoom mus ncig thiab yog li txhim kho qhov ua tau zoo, tuaj yeem yog cov neeg sib tw zoo. Tsis tas li ntawd, cov chips nrog siab - cov qauv siv lead ua zoo thiab cov doping cov ntaub ntawv ua tau zoo ua rau cov khoom siv hluav taws xob zoo dua - qhov sib xyaw ua ke, ua rau muaj kev ua tau zoo luminous.
2. Optimizing tshav kub dissipation tsim
Kev tswj cua sov yog qhov tseem ceeb hauv kev tswj kom muaj kev ua haujlwm siab luminous, tshwj xeeb tshaj yog nyob rau hauv qhov chaw kaw Φ60mm. LEDs tsim hluav taws xob thaum lub sijhawm ua haujlwm, thiab yog tias qhov cua sov no tsis ua kom zoo, cov nti kub yuav nce, ua rau muaj qhov tshwm sim hu ua "kev ua haujlwm poob qis" qhov twg qhov kev ua tau zoo luminous txo qis.
Txhawm rau hais txog qhov no, cov cua sov siab tshaj - cov khoom dab dej nrog cov thermal conductivity yog ua haujlwm. Cov ntaub ntawv zoo li tooj liab thiab txhuas feem ntau yog siv, tab sis ntau txoj kev xaiv xws li graphite - raws li cov khoom sib xyaw lossis pob zeb diamond - cov ntaub ntawv txhim kho tuaj yeem muab cov cua sov zoo dua - hloov khoom. Thaum tshav kub kub - dab dej tsim yuav tsum ua kom qhov chaw saum npoo av kom muaj cua sov. Fin - hom cua sov - dab dej nrog ntau tus nyias nyias, ze - spaced fins tuaj yeem ua rau thaj chaw sib cuag nrog huab cua ib puag ncig, ua kom yooj yim dua cov cua sov hloov.
Tsis tas li ntawd, cov khoom siv hluav taws xob sib txuas nrog cov thermal tsis zoo yog siv los ua kom muaj cua sov zoo ntawm cov nti LED thiab cov cua sov - dab dej. Cov ntaub ntawv no, xws li siab - zoo thermal greases los yog theem - hloov cov ntaub ntawv, pab txuas rau txhua qhov sib txawv ntawm cov nti thiab cov cua sov - dab dej, txo cov thermal kuj ntawm lub interface.
3. Tsim ib qho Optimal Optical System
Lub tshuab kho qhov muag ua lub luag haujlwm tseem ceeb hauv kev rho tawm thiab coj lub teeb tawm los ntawm LED nti kom ua tiav cov txiaj ntsig zoo. Hauv Φ60mm ntim, ua tib zoo tsim cov khoom siv kho qhov muag yuav tsum tau.
Ua ntej, kev xaiv ntawm phosphor yog qhov tseem ceeb rau dawb - lub teeb - tsim LEDs. Phosphors nrog kev hloov pauv siab ua haujlwm, kev nqus dav dav, thiab nqaim emission spectra yog nyiam. Piv txwv li, qee qhov tshiab tsis tshua muaj - ntiaj teb - doped phosphors tuaj yeem hloov lub teeb xiav los ntawm LED nti mus rau lwm cov xim nrog kev ua haujlwm siab, ua rau muaj kev sib npaug ntau dua - lub teeb spectrum. Lub phosphor txheej thickness thiab uniformity kuj yuav tsum tau optimized. Lub qhov dej - tswj phosphor txheej tuaj yeem ua kom lub teeb hloov dua siab tshiab thiab sib xyaw ua ke, tsis tas yuav ua rau nws tus kheej ntau dhau - nqus los yog lub teeb tawg uas tuaj yeem txo qhov kev ua tau zoo ntawm luminous tag nrho.
Qhov thib ob, lub lens optical lossis reflectors yog tsim los ua kom muaj txiaj ntsig zoo thiab coj lub teeb. Precision - moulded lo ntsiab muag ua los ntawm siab - zoo optical plastics los yog iav tuaj yeem siv los ua lub teeb pom kev zoo. Reflectors nrog siab - reflectivity coatings, xws li txhuas nrog ib tug heev polished nto los yog tshwj xeeb dielectric coatings, muaj peev xwm redirect lub teeb uas yuav tsis tau ploj, ua rau tag nrho cov teeb tso zis nyob rau hauv cov kev xav tau.
4. Advanced Driver Electronics
Tus tsav tsheb hluav taws xob siv hluav taws xob LED kuj cuam tshuam rau kev ua haujlwm luminous. High - efficiency LED tsav tsheb uas tsis muaj zog poob yog qhov tseem ceeb. Hloov - hom khoom siv fais fab, xws li phaw, boost, lossis puck - boost converters, tuaj yeem tsim los ua haujlwm ntawm kev ua haujlwm siab, feem ntau siab dua 90%. Cov tsav tsheb no tswj cov tam sim no ntws los ntawm LED kom meej, ua kom muaj kev ruaj ntseg
Ntxiv mus, tus neeg tsav tsheb tuaj yeem tsim los ua haujlwm ntawm qhov zoo tshaj plaws kom txo qis kev hloov pauv. Qee cov tsav tsheb siab heev kuj suav nrogfais fab - yam - kho (PFC) circuits. PFC circuits txhim kho lub zog ntawm lub teeb pom kev zoo, txo cov hluav taws xob reactive thiab xyuas kom meej tias cov hluav taws xob siv hluav taws xob zoo dua. Los ntawm kev txo qis lub zog poob hauv cov tsav tsheb hluav taws xob, lub zog hluav taws xob ntau tuaj yeem hloov mus rau hauv cov khoom siv teeb pom kev zoo, ua rau kom ua tiav qhov ua tau zoo luminous hauv Φ60mm ntim.
In conclusion, achieving a luminous efficacy of >90lm/W nyob rau hauv ib qho ultra - me me Φ60mm ntim yuav tsum tau ib tug kev mus kom ze uas encompasses kev xaiv ntawm siab - zoo LED chips, zoo tshav kub dissipation, optimized optical tsim, thiab advanced tsav electronics. Los ntawm kev sib koom ua ke cov tswv yim no, nws muaj peev xwm tsim cov teeb pom kev zoo uas muaj txiaj ntsig zoo thiab kev cog lus, ua tau raws li qhov xav tau ntawm ntau yam kev siv hauv ntau qhov kev lag luam.
