Muaj pes tsawg watts ib 'meter' ntawm cob lub teeb sawb?

Ntawm 5 watts thiab 20 watts

Lub zog ntawm ib meter ntawm COB lub teeb sawb feem ntau yog nruab nrab ntawm 5 watts thiab 20 watts, thiab lub zog tshwj xeeb nyob ntawm tus qauv tsim ntawm lub teeb sawb.

Lub zog ntawm COB lub teeb strips yog txiav txim siab los ntawm nws cov qauv tsim tshwj xeeb, thiab lub zog ntawm COB lub teeb strips yuav txawv. Feem ntau hais lus, lub zog ntawm ib lub 'meter' ntawm COB lub teeb strips feem ntau yog nruab nrab ntawm 5 watts thiab 20 watts, thiab qee lub npe tau tshaj tawm lub zog ntau dua COB lub teeb strips. Yog li ntawd, wattage ntawm ib-meter COB lub teeb sawb yuav tsum tau ua raws li cov qauv tsim ntawm lub teeb sawb.

4 yam tseem ceeb cuam tshuam rau lub zog ntawm COB lub teeb strips

Cov laj thawj tseem ceeb uas cuam tshuam rau lub zog ntawm COB lub teeb strips yog raws li hauv qab no:

Tus naj npawb thiab qhov loj ntawm COB teeb hlaws: Lub zog thiab ci ntsa iab ntawm COB teeb strips muaj feem xyuam rau tus lej thiab qhov loj ntawm COB teeb hlaws. Feem ntau hais lus, ntau COB teeb hlaws hlaws thiab qhov loj dua qhov loj ntawm COB teeb sawb, qhov siab dua lub zog thiab qhov ci.

Thaum tshav kub kub dissipation nyhuv: Lub luminous efficiency ntawm COB teeb hlaws yuav txo qis thaum qhov kub nce. Yog li ntawd, lub tshav kub dissipation nyhuv ntawm COB lub teeb strips yuav cuam tshuam nws lub zog thiab ci ntsa iab. COB lub teeb strips nrog zoo cua sov dissipation tuaj yeem tswj lub zog ruaj khov thiab ci ntsa iab.

Tsav tam sim no: Lub zog siab tshaj plaws thiab ci ntsa iab ntawm COB teeb hlaws nyob ntawm lawv qhov siab tshaj plaws tsav tam sim no. Lub zog thiab ci ntsa iab ntawm COB lub teeb strips cuam tshuam nrog kev tsav tsheb tam sim no lawv tau nruab nrog.

PCB board thickness thiab zoo: PCB board yog lub substrate ntawm COB lub teeb sawb thiab tseem yuav cuam tshuam rau nws lub zog thiab ci. Qhov zoo dua qhov tuab thiab zoo ntawm PCB pawg thawj coj saib, qhov zoo dua qhov kev sib kis tam sim no thiab cov cua sov dissipation, thiab qhov siab dua lub zog thiab qhov ci ntawm lub teeb sawb.

Lub zog thiab ci ntsa iab ntawm COB lub teeb ci yog nyob ntawm qhov sib xyaw ua ke ntawm ntau yam xws li tus naj npawb thiab qhov loj ntawm COB teeb hlaws, cov nyhuv tshav kub dissipation, tsav tam sim no, thiab thickness thiab zoo ntawm PCB board.

Yuav ua li cas xam lub zog ntawm COB lub teeb sawb?

Kev suav fais fab ntawm COB lub teeb strips yuav tsum xav txog cov hauv qab no:

Voltage thiab tam sim no ntawm txhua LED nti: Feem ntau muaj ntau yam LED chips ntawm COB lub teeb sawb. Qhov voltage thiab tam sim no ntawm txhua LED nti sib txawv, yog li lawv yuav tsum tau muab xam rau nyias, thiab tom qab ntawd ntxiv ua ke kom tau txais lub zog ntawm tag nrho lub teeb sawb.

Tus naj npawb thiab kev npaj ntawm LED chips: Tus naj npawb thiab kev teeb tsa ntawm LED chips ntawm COB teeb sawb kuj tseem cuam tshuam rau kev suav lub zog. Feem ntau hais lus, LED chips ntau dua, lub zog ntau dua.

Rated zog ntawm kev tsav tsheb fais fab mov: Lub zog tsav tsheb siv los ntawm COB lub teeb sawb kuj tseem cuam tshuam rau kev suav lub zog, vim tias qhov ntsuas lub zog ntawm lub zog hluav taws xob ntau dua li lub zog ntawm lub teeb sawb.

Raws li cov ntsiab lus saum toj no, cov qauv kev suav fais fab ntawm COB lub teeb sawb yog raws li hauv qab no:

Fais fab = ∑ (Voltage ntawm txhua LED nti × Tam sim no ntawm txhua LED nti) × Tus naj npawb ntawm LED chips × Txheej coefficient

Ntawm lawv, qhov kev npaj coefficient feem ntau yog 1, uas txhais tau hais tias cov chips LED tau teeb tsa hauv txoj kab.

Nws yuav tsum raug sau tseg tias kev suav lub zog ntawm COB lub teeb sawb tsuas yog siv tau raws li kev siv. Hauv kev siv tiag tiag, yam xws li cov cua kub dissipation ntawm lub teeb sawb thiab qhov sib txuam ntawm lub zog tsav tsheb yuav tsum tau txiav txim siab los xyuas kom meej tias muaj kev nyab xeeb thiab ruaj khov ua haujlwm ntawm lub teeb sawb.
