Dab tsi yog cov txheej txheem kub dissipation ntawm LED txoj kev teeb?

Lub tshav kub dissipation ntawm LED txoj kev teeb yog ib qho teeb meem uas yuav tsum tau daws, uas tsis yog tsuas yog ncaj qha cuam tshuam rau lub luminous efficiency ntawm LED tiag tiag ua hauj lwm, tab sis kuj vim hais tias ntawm lub siab brightness yuav tsum tau ntawm LED txoj kev teeb, loj tshav kub tso zis, thiab qhov chaw siv sab nraum zoov yog hnyav, yog tias qhov cua sov dissipation tsis zoo, nws yuav ncaj qha ua rau kev laus sai ntawm LED thiab txo kev ruaj ntseg. Vim tias txoj kev teeb pom kev zoo siv sab nraum zoov yuav tsum muaj qee theem ntawm plua plav thiab dej tsis zoo (IP), kev tiv thaiv IP zoo feem ntau tiv thaiv kom tsis txhob muaj cua sov ntawm LED.

Txhawm rau daws qhov kev tsis sib haum xeeb no tab sis kuj yuav tsum tau daws ob qhov teeb meem yog ib qho tseem ceeb ntawm txoj kev teeb pom kev zoo tsim yuav tsum muaj kev txhawj xeeb txog. Nyob rau hauv qhov kev hwm no, nws tseem yog qhov tsis tsim nyog thiab tsis tsim nyog qhov teeb meem thaum lub LED siv rau txoj kev teeb hauv Suav teb. Tam sim no, cov xwm txheej tsis tsim nyog thiab tsis tsim nyog hauv kev siv hauv tsev yog qhov tseem ceeb:

(1) Lub tshuab hluav taws xob yog siv rau LED, tab sis qhov tsim ntawm cov khoom siv hluav taws xob thiab lub tshuab hluav taws xob ntawm LED txuas tsis tuaj yeem ncav cuag IP45 lossis siab dua qib, thiab tsis tuaj yeem ua tau raws li GB7000.5/IEC6598-2-3

Cov kev cai ntawm tus qauv.

(2) Kev siv cov teeb pom kev zoo tib yam lub plhaub, nyob rau hauv lub teeb ntawm lub teeb nrog matrix LED, txawm hais tias qhov kev tsim no tuaj yeem ua tau raws li IP xeem, tab sis vim tsis muaj qhov cua hauv lub teeb yuav ua rau ntawm kev ua haujlwm, qhov kub ntawm lub teeb. chamber yuav nce mus rau 50 degree C ~ 80 degree C, nyob rau hauv xws li ib tug siab ua hauj lwm mob, lub luminous efficiency ntawm lub LED yog tsis yooj yim sua kom siab, thiab cov kev pab cuam lub neej ntawm lub LED kuj yuav loj luv nqi, qhov tseeb, muaj cuab kev. xwm txheej tsis tsim nyog.

(3) Lub twj tso kua mis twj tso kua mis yog siv nyob rau hauv lub teeb kom dissipate tshav kub ntawm LED thiab radiator, thiab cov cua inlet yog tsim nyob rau hauv lub teeb kom tsis txhob nkag los ntawm nag, thiab cua qhov hluav taws xob yog tsim nyob ib ncig ntawm lub LED teeb qhov chaw. Qhov no tuaj yeem ua tau zoo kom tsis txhob nkag los nag, ntxiv rau lub tshuab hluav taws xob thiab LED (lub teeb kab noj hniav) tsis nyob hauv tib qhov khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob khoob dhau. Qhov kev daws teeb meem no tsis yog tsuas yog daws qhov teeb meem ntawm kev kub ntxhov ntawm LED, tab sis kuj ua tau raws li qhov yuav tsum tau ua ntawm qib IP.

Tab sis qhov no zoo nkaus li tsim, qhov tseeb, muaj cov xwm txheej tsis sib haum xeeb. Vim tias nyob rau hauv kev siv cov teeb pom kev loj hauv Suav teb, qhov ntau ntawm cov plua plav ya hauv huab cua yog qhov loj, thiab qee zaum nws yuav ncav cuag ntau npaum li cas (xws li cua daj cua dub), tom qab cov teeb pom kev zoo li no tau siv nyob rau hauv cov xwm txheej dav dav. Lub sij hawm ntawm lub sij hawm (kwv yees li peb lub hlis mus rau rau lub hlis), qhov sib txawv nyob rau hauv lub radiator sab hauv yuav muaj cov plua plav, thiaj li hais tias lub radiator nyhuv yog heev txo, thiab thaum kawg lub LED yuav siv tau vim lub siab ua hauj lwm kub lub neej yog luv luv. Qhov tsis zoo ntawm cov txheej txheem no yog tias nws tsis tuaj yeem siv tau ntev.
