Qhov pom tseeb tshaj qhov sib txawv ntawm cov high-power LEDs thiab low-power LEDs nyob rau hauv lawv lub hwj chim thiab brightness. Qhov ntsuas tam sim no ntawm lub zog qis LED feem ntau yog 20mA, thiab nws lub zog feem ntau yog nruab nrab ntawm 0.03W thiab 0.1W, nrog rau qhov ci ci feem ntau hauv millicandela (mcd). Txawm hais tias qhov ci ntsa iab ntawm lub zog hluav taws xob tsawg tsawg tsawg, lawv qhov kub thiab qhov sib txawv tsis zoo ua rau lawv muaj txiaj ntsig zoo hauv qee qhov xwm txheej, xws li teeb pom kev, teeb pom kev zoo, thiab lwm yam.
Nyob rau hauv sib piv, lub hwj chim ntau ntawm high-power LEDs yog dav npaum li cas, xws li ntawm 0.25W mus rau 100W, nrog rau tej lub zog xws li 0.5W, 1W, 3W, 5W, 8W, 10W, thiab lwm yam. Lub teeb ci ntawm lub zog siab LEDs feem ntau yog lumens (lm), nrog qhov ci ci ntawm 110LM thiab 260LM, lossis ntau dua. Lub hwj chim siab coj tau qhov zoo ntawm qhov ci ntsa iab, ua rau lub zog muaj zog LEDs dav siv hauv tsev thiab sab nraum zoov teeb pom kev zoo, teeb pom kev lag luam, teeb pom kev lag luam, thiab lwm yam.
2, Ntim txheej txheem thiab lub teeb attenuation
Nyob rau hauv cov nqe lus ntawm ntim tshuab, muaj qhov sib txawv tseem ceeb ntawm high-power LEDs thiab low-power LEDs. Lub zog loj LEDs feem ntau siv ntau txoj kev ntim khoom xws li cov ntim loj epoxy resin ntim, piranha zoo li epoxy resin ntim, aluminium substrate (MCPCB) ntim, TO ntim, thiab lub hwj chim hom SMD ntim. Cov txheej txheem ntim no tsis tsuas yog txhim kho cov cua sov ua haujlwm ntawm LEDs, tab sis kuj txhim kho lawv txoj kev ruaj khov thiab kav ntev.
Tsis tas li ntawd, muaj qhov sib txawv ntawm lub teeb attenuation ntawm high-power LEDs thiab low-power LEDs. Lub teeb lwj yog hais txog qhov tshwm sim uas qhov ci ntawm LED maj mam txo qis vim muaj ntau yam laj thawj thaum siv. Vim lawv lub zog loj thiab cov yam ntxwv ci ntsa iab, lub zog loj LEDs muaj qhov teeb meem tseem ceeb dua qhov teeb meem. Yog li ntawd, thaum xaiv high-power LEDs, nws yog ib qhov tsim nyog yuav tau xyuam xim rau lawv cov degree ntawm lub teeb lwj thiab xaiv cov khoom uas tsis muaj lub teeb lwj kom ntseeg tau tias lawv cov hauj lwm ntev.
3, Daim ntawv thov cheeb tsam thiab cov cua kub dissipation yuav tsum
Nyob rau hauv cov nqe lus ntawm daim ntawv thov teb, high-power LEDs thiab low-power LEDs txhua tus muaj lawv tus kheej zoo. Lub zog qis LEDs tau dav siv nyob rau hauv qhov taw qhia teeb, teeb liab teeb, teeb pom kev zoo, thiab lwm yam kev lag luam vim lawv lub zog siv tsawg, muaj kev ntseeg siab, thiab lub neej ntev. Cov sijhawm no tsis tas yuav muaj qhov ci ntsa iab thiab lub zog loj, tab sis muaj cov kev xav tau siab rau kev ruaj ntseg thiab kav ntev, thiab cov LEDs tsis tshua muaj zog ua tau raws li cov kev xav tau no.
Lub zog siab LEDs tau dav siv nyob rau hauv tsev thiab sab nraum zoov teeb pom kev zoo, coj mus muag teeb pom kev zoo, muaj teeb pom kev zoo, thiab lwm yam kev lag luam vim lawv lub siab ci thiab lub zog siab. Cov sijhawm no yuav tsum muaj qhov ci ntsa iab thiab lub zog siab, thaum tseem xav txog cov teeb meem kub ntxhov. Vim tias cov LEDs muaj zog ua kom muaj cua sov ntau thaum lub sijhawm ua haujlwm, cov cua kub tsis zoo tuaj yeem ua rau LED kub nce, yog li cuam tshuam rau nws cov kev ua haujlwm thiab kev pabcuam lub neej. Yog li ntawd, thaum xaiv high-power LEDs, nws yog ib qho tsim nyog yuav tsum tau them sai sai rau lawv cov cua kub dissipation kev ua tau zoo thiab xaiv cov khoom nrog zoo thermal dissipation qauv.
4, Thaum tshav kub kub dissipation technology thiab xaiv cov khoom siv
Nyob rau hauv cov nqe lus ntawm cua kub dissipation technology, muaj qhov sib txawv tseem ceeb ntawm high-power LEDs thiab low-power LEDs. Txhawm rau txhim kho kev ua haujlwm ntawm cov cua sov, cov khoom siv hluav taws xob muaj zog feem ntau siv ntau yam cua kub dissipation xws li hlau cua sov dab dej, cua kub dissipation kiv cua, thiab ua kua txias. Cov txheej txheem kub dissipation no tsis tsuas yog txhim kho lub tshav kub dissipation efficiency ntawm LEDs, tab sis kuj txuas lawv lub neej kev pab cuam.
Nyob rau hauv cov nqe lus ntawm kev xaiv cov khoom siv, high-power LEDs kuj tseem ceeb dua rau kev ua kom sov dissipation. Piv txwv li, siv cov ntaub ntawv xws li hlau kub dab dej thiab ceramic kub dab dej nrog siab thermal conductivity los txhim kho tshav kub dissipation efficiency. Tsis tas li ntawd, txhawm rau txhim kho kev ntseeg siab thiab ua haujlwm ntev ntawm LEDs, nws yog ib qho tsim nyog yuav tsum xaiv cov khoom ntim khoom zoo thiab tsav tsheb.
5, Nqe thiab tus nqi zoo
Nyob rau hauv cov nqe lus ntawm tus nqi, high-power LEDs feem ntau kim tshaj li tsawg-power LEDs. Qhov no yog vim hais tias high-power LEDs muaj kev ua tau zoo dua cov kev xav tau ntawm lub zog, ci ntsa iab, cua sov dissipation, thiab lwm yam, thiab yuav tsum tau siv cov khoom siv ntau dua thiab cov txheej txheem rau kev tsim khoom. Txawm li cas los xij, los ntawm qhov kev xav ntawm tus nqi-ua tau zoo, LEDs siab zog muaj qhov zoo hauv qee qhov xwm txheej. Piv txwv li, nyob rau hauv cov xwm txheej uas yuav tsum tau muaj kev ci ntsa iab thiab lub zog siab, kev siv lub zog siab LEDs tuaj yeem txuag tau ntau lub zog thiab cov nqi, txhim kho teeb pom kev zoo thiab kev ua neej.
