Los ntawm kev tswj hwm cua sov kom zoo, kev poob zog vim yog kev sib sau ua ke ntawm cua sov raug txo kom tsawg, ua kom ntseeg tau tias ntau lub zog muab rau LED strip raug hloov mus ua lub teeb es tsis txhob raug pov tseg ua cua sov. Qhov no kuj ua kom muaj lub neej ntev, uas pab txhawb kev siv hluav taws xob tsis ncaj qha los ntawm kev txo qhov zaus ntawm kev hloov pauv.

Kev Tswj Xyuas Zoo thiab Cov Qauv Kev Ruaj Ntseg

Kev ua kom lub zog siv tau zoo tsis yog nyob ntawm kev tsim qauv thiab thev naus laus zis xwb; kev tswj xyuas zoo thiab kev ua raws li cov qauv kev ruaj khov yog qhov tseem ceeb heev. Cov chaw tsim khoom siv cov txheej txheem kuaj xyuas zoo thoob plaws hauv kev tsim khoom kom paub tseeb tias cov LED strips ua tau raws li lossis tshaj cov qauv kev ua haujlwm hluav taws xob uas tau teeb tsa.

Cov txheej txheem kuaj mob suav nrog kev kuaj photometric, qhov twg qhov tso zis luminous thiab kev siv hluav taws xob raug ntsuas nyob rau hauv cov xwm txheej tswj hwm kom xam cov piv ntawm kev ua haujlwm tau zoo. Kev kuaj kev nyab xeeb hluav taws xob ua kom ntseeg tau tias tsis muaj hluav taws xob xau ntau dhau lossis luv luv circuits uas yuav ua rau kev ua haujlwm tsis zoo.

Hauv qhov ntsuas loj dua, kev ua raws li cov ntawv pov thawj thoob ntiaj teb txog lub zog xws li ENERGY STAR lossis IEC cov qauv qhia txog kev cog lus ntawm cov chaw tsim khoom rau kev siv hluav taws xob zoo. Cov ntawv pov thawj no yuav tsum tau cov khoom kom dhau cov kev cai nruj ntsig txog kev siv hluav taws xob, lub neej ntev, thiab kev cuam tshuam rau ib puag ncig.

Kev ruaj khov kuj tseem siv cov khoom siv uas tsis muaj tshuaj lom, cov khoom siv rov ua dua tshiab hauv kev tsim cov LED strip thiab cov ntim khoom uas tsis ua rau ib puag ncig puas tsuaj. Cov kev coj ua tsim khoom uas ruaj khov txo qhov cuam tshuam ntawm ib puag ncig, ua kom cov khoom siv hluav taws xob zoo sib xws nrog cov hom phiaj dav dua ntawm kev saib xyuas ib puag ncig.

Cov chaw tsim khoom pheej saib xyuas cov lus tawm tswv yim ntawm kev ua lag luam thiab nqis peev rau kev tshawb fawb thiab kev txhim kho kom zoo dua cov txheej txheem tsim khoom. Lub voj voog txhim kho no ua kom ntseeg tau tias cov LED strips tseem nyob rau pem hauv ntej ntawm kev siv hluav taws xob zoo thaum thev naus laus zis thiab kev cia siab ntawm ib puag ncig hloov pauv.

Hauv kev xaus lus, txoj kev mus rau lub teeb pom kev zoo LED uas siv hluav taws xob tsawg yog qhov nyuaj thiab muaj ntau yam. Txij li kev xaiv cov khoom siv zoo thiab kev tsim cov chip tshiab mus rau cov thev naus laus zis tsav tsheb siab heev thiab kev tswj hwm thermal ua ntej, txhua yam me me pab txo kev siv hluav taws xob thaum ua kom lub teeb ci ntau tshaj plaws. Kev tswj hwm zoo thiab kev ua raws li cov qauv kev ruaj khov ua kom cov khoom kawg ua haujlwm tau zoo hauv lub ntiaj teb tiag tiag, muab kev txuag hluav taws xob mus sij hawm ntev rau cov neeg siv khoom.

Thaum kev siv hluav taws xob zoo dua qub hauv kev daws teeb pom kev zoo, cov chaw tsim khoom LED strips tseem mob siab rau kev tsim kho tshiab thiab kev ua tau zoo. Los ntawm kev thawb cov ciam teb thev naus laus zis thiab tswj cov qauv tsim khoom siab, lawv xa cov khoom uas tsis yog tsuas yog ci ntsa iab zoo nkauj xwb tab sis kuj pab txhawb rau yav tom ntej uas ruaj khov dua. Kev nkag siab txog cov kev siv zog no pab cov neeg siv khoom thiab cov neeg koom nrog kev lag luam txaus siab rau qhov kev txawj ntse tom qab cov kab teeb pom kev zoo no.
