LED Kev Lag Luam Raws Li Kev Lag Luam thiab Kev Loj Hlob Loj?

LED tau muab cov teeb meem tso tawm thiab cov hluav taws xob nthuav dav thiab lwm yam teeb meem ua tau zoo, yog li nws lub zog tsis tuaj yeem ua tau loj heev, tsis muaj ci. Tam sim no, feem ntau siv high-fais fab coj chips nrog cov kev ua tau ruaj khov yog 1w thiab 3w. LED zog tuaj yeem txhim kho los ntawm cov chips sib xyaw, tab sis tam sim no thev naus laus zis tsis paub tab, feem ntau yuav tsum daws cov teeb meem kub ntxhov. High-fais fab LED teeb kuj tseem tuaj yeem pom tau los ntawm koob, parallel lossis hybrid ntawm ntau-hlaws LED. Lub tom kawg ob qho tsis tshua muaj txiaj ntsig thiab siv tsawg dua, thiab ntau tus hlaws LED series yog tam sim no lub ntsiab ntawm LED teeb nyob rau hauv lub teeb pom kev zoo.

Daim ntawv thov ntawm LED teeb pom vim tias LED teeb muaj lub teeb tsis zoo thiab maj mam hloov lwm lub teeb, thiab tam sim no coj lub teeb nrawm tau siv dav hauv ntau lub teeb teb. Vim tias LED yog me me thiab yoog raws daim ntawv thov, yog li nws tuaj yeem tswj hwm los ntawm cov ntawv nyeem, duab, yeeb yaj kiab, zaj duab xis thiab TV. Hauv kev ua koob tsheej qhib ntawm xyoo 2008 Beijing Olympic Games, LED teeb pom nws qhov ntxim nyiam kawg thiab kev ntxim nyiam thiab zoo. LED tau siv dav hauv cov teeb pom pej xeem, xws li teeb pom kev zoo, thiab teeb tsa ua kua teeb tsa, kev ua yeeb yam ntawm kev ua yeeb yam rau cov ntxaij vab tshaus xws li khoos phis tawj, TV thiab xov tooj ntawm tes.

Ntawm txoj kev tsheb khiav tsheb, LED tau siv rau kev tswj hwm lub zog teeb pom kev zoo, qhov teeb pom kev zoo, kev teeb pom kev zoo, lub teeb liab thiab lwm yam. In terms of automotive lighting, many cars' brake lights, position lights, turn signals, rear fog lights, reverse lights and other lamps have begun to use LED light sources. Nrog rau kev txhim kho LED thev naus laus zis, kev tsim kho cov teeb pom kev zoo, lub zog ua rau sab hauv tsev, Studio, saib cov teeb pom kev zoo dua qub.

Txawm hais tias LED muaj ntau yam zoo, tab sis kuj tseem muaj ntau cov teeb meem tsis zoo thiab daws tau cov kev txhim kho ntxiv thiab cov hauv qab no los ntawm ntau yam ntawm nws tau tham txog.

1. Cov High-Fais Fab LED Tshuab. LED tau muab cov teeb meem tso tawm thiab cov hluav taws xob nthuav dav thiab lwm yam teeb meem ua tau zoo, yog li nws lub zog tsis tuaj yeem ua tau loj heev, tsis muaj ci. Tam sim no, feem ntau siv high-fais fab coj chips nrog cov kev ua tau ruaj khov yog 1w thiab 3w. LED zog tuaj yeem txhim kho los ntawm cov chips sib xyaw, tab sis tam sim no thev naus laus zis tsis paub tab, feem ntau yuav tsum daws cov teeb meem kub ntxhov. High-fais fab LED teeb kuj tseem tuaj yeem pom tau los ntawm koob, parallel lossis hybrid ntawm ntau-hlaws LED. Lub tom kawg ob qho tsis tshua muaj txiaj ntsig thiab siv tsawg dua, thiab ntau tus hlaws LED series yog tam sim no lub ntsiab ntawm LED teeb nyob rau hauv lub teeb pom kev zoo. Tab sis tib tus hlaws tandem muaj kev ua phem, ib qho kev puas tsuaj, tag nrho txoj kev thaiv. Qhov no yog qhov tseem ceeb bottleneck txwv txoj kev thov ntawm high-zog coj teeb nyob rau hauv lub teeb pom kev zoo. Txhawm rau txhim kho lub zog ntawm LED teeb, ib qho yog txhawm rau txhim kho lub zog los ntawm cov qauv hluav taws xob, thiab lwm qhov yog txhawm rau txhim kho lub zog.

2. Technology txias. Qhov kub yog qhov tseem ceeb cuam tshuam rau cov LED, qhov kub yuav ua rau lub teeb pom kev zoo, yog li lub zog ntawm LED thaum muaj kev cuam tshuam kub disspipation muaj peev xwm txwv lub zog ntawm tus LED Cov.

Cov cua sov sab hauv cov LED yog qhov tsim tawm thaum cov LED nti thiab luam tawm cov cua sov uas muaj peev xwm cuam tshuam, tab sis rau lub zog hluav taws xob tau cuam tshuam, nws yog qhov tsim nyog los txiav txim siab ntau yam ntawm tshav kub dissipation. Nyob rau hauv tshav kub dissipation tsim, nws yog feem ntau yog los ntawm cov pob ntawm LED pob Thaum tshav kub kub dissipation, Circuit Coursipation thiab nce ntxiv dej kub dissipation Cheebtsam.

3. Chip Technology thiab Chip TV thev naus laus zis. Tus yuam sij rau kev txhim kho ntawm chip thev naus laus zis yog kev xaiv ntawm cov khoom siv substrate thiab cov thev naus laus zis ntawm kev xaiv tau. Tus yuam sij rau kev txhim kho technology yog txhawm rau txo cov khoom siv tsis zoo thiab ruaj khov, thiab cov khoom siv ruaj khov yog qhov tseem ceeb tshaj plaws ntawm cov ntsuas kev ua haujlwm tag nrho. Cov tsoos substrate yog Sapphire, Si, Sic, thiab Zno, Gan thiab lwm yam. Lub ntsiab ntawm kev ua cov ntawv xaiv kab ntawv yog hlau-organic tshuaj vapor deposition. Raws li 2011 Qhia LED Ntiaj Teb Online Online, University of North Carolina Kev Tsim Kho Lub Teeb Pom Kev Loj Hlob Loj LED Lub Teeb-Emitting Diode.

4. Kev tsim kho kho qhov muag. LED yog lub teeb pom kev zoo thiab qhov kev tsim qauv zoo nkauj thiab muaj cov qauv faib tawm tshiab tsim kho, koj tuaj yeem ua tiav qhov nyuaj ntawm kev tsim qauv. Nyob rau hauv tag nrho cov teeb ci tag nrho, lub teeb yuav tsum tau muaj irradiation nto, uas tuaj yeem ua rau hauv lub qhov chaw teeb hluav taws xob uas siv cov kab lus coj nrog lub teeb taw qhia nrog lub teeb taw qhia thiab lwm yam thev naus laus zis. LED lub tsheb teeb pom kev tuaj yeem tsim cov kev cuam tshuam thiab tsom iav, los ntawm kev tsim qauv tsim nyog tuaj yeem ua tiav qhov teeb tsa teeb meem.

5. Tsav thev naus laus zis. LED Tas cov tsav tsheb tam sim no feem ntau muaj ob hom coj tsav tsheb: inductive hom capacitor hom. Inductive hom LED tsav tau muaj zog tam sim no thiab qis LED chaw haujlwm hluav taws xob, uas yog tsim rau kev tsav tsheb ntau daim ntawv thov LED. Peev tau siv tau cov tsav tsheb yog feem ntau siv nyob rau hauv high-fais fab LED teeb, uas nws LED lub zog hluav taws xob thiab tam sim no yog qhov siab, thiab muaj zog thiab muaj luminous ua tau zoo. Tus qauv tsim ntawm lub LED Tsav Tsheb Circuit Circuit Court raws li cov kev xav tau tshwj xeeb, tab sis nws yog qhov tsim nyog los txiav txim siab muaj kev ruaj ntseg ntau yam xws li kev tiv thaiv kev siv hluav taws xob ntawm Circuit Court thaum tsim lub Circuit Court thaum tsim Circuit Court.

Ntxiv rau cov teeb meem saum toj no los ntawm LED teeb, muaj cov teeb meem xws li cov qauv tsim kev siv tshuab los ua kev txhim kho ntxiv. Tsis tas li ntawd, tsis muaj kev sib koom ua ke cuam tshuam hauv kev lag luam LED.

LED Zog Txuag thiab ib puag ncig kev pabcuam ntev kev pabcuam lub neej yog dc volarage, yog lub teeb corged ntsuab, yog lub teeb ci ntsa iab hauv daim ntawv thov tsis tau Yuav tsum tau hloov dua lwm txoj kev hloov tshiab tam sim no rau hauv qhov tam sim no ncaj qha, yog li ua kom siv tau yooj yim thiab yooj yim. Thiab peb cov teeb meem kev sib raug zoo thiab cov teeb meem papoutic yuav muaj kev txhim kho zoo heev. Yog li ntawd, kev sib xyaw ua ke ntawm LED thiab hnub ci zog yuav yog txoj kev tsis paub txog kev teeb pom kev zoo yav tom ntej. Txog tam sim no, muaj ob peb daim ntawv thov nyob rau hauv qhov hais txog, thiab muaj twb tau muaj txoj kev teeb tsa lub teeb, Hnub ci coj cov nyom teeb thiab lwm yam.

LED Zog Txuag thiab ib puag ncig kev txhim kho lub neej ntev, muaj lub zog loj, LED teeb nyob rau hauv kev siv teeb pom kev zoo yuav nrov, LED teeb yuav tob rau hauv Tib neeg lub teeb pom kev zoo txhua hnub, lub neej, tsheb khiav. LED teeb thiab kev sib xyaw ua ke ntawm LED thiab hnub ci zog yuav dhau los ua lub zog tseem ceeb hauv yav tom ntej teeb pom kev zoo.
