LED thev naus laus zis feem ntau tau qhuas rau lawv cov kev ua haujlwm zoo dua thiab txo qis cua sov. Yog li ntawd, nws yuav ua rau koj xav tsis thoob thaum pom LED sawb teeb tig sov lossis kub thaum nws ua haujlwm. Puas yog LED strips feem ntau tau sov los yog kub hnyiab rau qhov kov? Vim li cas qhov no tshwm sim? Tsuas yog kub npaum li cas thiaj nyab xeeb? Tshawb nrhiav los ntawm kev nyeem ntawv!
Pib nrog, nws yog ib qho tseem ceeb rau LEDs ua kom sov. Tab sis vim li cas LEDs tau sov nyob rau hauv thawj qhov chaw, xav txog txhua yam uas tau hais txog kev ua haujlwm zoo thiab txias npaum li cas?
Txawm hais tias qhov tseeb tias LEDs muaj txiaj ntsig zoo dua li cov qauv teeb pom kev zoo, lawv tseem tsis tau muaj txiaj ntsig. Thaum peb tham txog cov lej ua haujlwm, lawv feem ntau hais tias feem pua. Qhov no qhia peb ntau npaum li cas hluav taws xob hloov pauv mus rau lub teeb siv tau thiab ntau npaum li cas poob raws li lub zog cua sov.
Cov qib ua tau zoo rau LEDs feem ntau yog li ntawm 30 feem pua rau 50 feem pua. Raws li, rau txhua 100 watts ntawm hluav taws xob input siv los ntawm tus qauv LED nrog 40 feem pua kev ua tau zoo, tsuas yog 40 watts raug tso tawm raws li lub zog siv tau (xws li teeb pom kev zoo), thaum lwm qhov 60 watts raug tso tawm raws li cua sov.
Ntxiv qhov chaw thiab ua-nyob rau hauv tsis kam nyob rau hauv circuitry yuav txo tau cov efficiency ntawm LED strips. Raws li qhov tshwm sim, LED strips feem ntau ua haujlwm ntawm 30 feem pua ntawm kev ua haujlwm. Qhov no txhais tau hais tias 90 watt LED sawb lub teeb reel yuav tsim 63 watts ntawm thermal zog (90 watts x 70 feem pua), uas yog roughly sib npaug rau cov cua sov uas tsim los ntawm 60 watt incandescent noob, uas raws li koj yuav nco ntsoov los ntawm kev paub, yeej tau txais. sov.
Qhov tseeb tias LEDs tsis zoo li koj tau ntseeg yuav ua rau koj xav tsis thoob! Txawm li cas los xij, piv rau cov teeb ci incandescent, uas muaj qhov ua tau zoo ntawm 5 feem pua lossis tsawg dua, LEDs yog qhov tseeb muaj txiaj ntsig zoo dua. Qhov tsis zoo ntawm lub teeb lub zog tawm los ntawm qhov muag teeb, nrog rau ntau ntawm nws nyob rau hauv ntev wavelengths xws li sib sib zog nqus liab thiab infrared wavelengths, uas tsis pab ntau, yog hais tias tag nrho, rau teeb pom kev zoo, yog lwm yam ua hauj lwm tiv thaiv lawv. Vim nyob rau hauv ib feem ntawm lawv txoj kev sim los npog qee qhov liab thiab sib sib zog nqus liab wavelengths uas yuav tsum tau rau cov xim rendering kom zoo, siab CRI LEDs yog ho tsis tshua muaj npaum li lawv niaj hnub counterparts.
Koj tuaj yeem mus li cas? Nws puas ruaj ntseg?
CEEB TOOM: Cov ntaub ntawv hauv qab no tsuas yog siv los ua ib qho kev siv thiab siv rau kev kawm txuj ci. Peb tsis muaj kev lav phib xaub rau txhua yam kev puas tsuaj lossis kev raug mob uas tshwm sim los ntawm kev siv cov ntaub ntawv qhia hauv qab no.
Qhov zoo thiab tsim ntawm LED sawb, nrog rau qhov kub thiab txias nyob ib puag ncig, yuav cuam tshuam rau qhov sov so ntawm LED sawb thaum ua haujlwm. Txij li Waveform Teeb pom kev zoo LED strips yog lub zog siab thiab siab ceev, lawv ua kom sov sai dua li lwm cov teeb ci LED. Qhov nruab nrab kub nce tshaj ambient temps yog 54 degree F (30 degree), raws li peb ntsuas. Hauv lwm lo lus, koj tuaj yeem cia siab tias yuav muaj LED sawb kom ncav cuag qhov kub ntawm 129 degree F (54 degree) nyob rau hauv ib qho chaw nrog chav tsev kub ntawm 75 degree F (24 degree).
Yog tias tsis tsim qee qhov kev txwv dav ntawm qhov ntsuas kub thiab qhov tshwj xeeb xav txog kev kub ntxhov, nws tuaj yeem nyuaj los txiav txim siab seb lub sawb LED puas yog "kub dhau" rau qee daim ntawv thov. Cov nram qab no peb teeb meem nrog LED sawb thermal yam ntxwv yog ib yam:
1) Puas yog tib neeg thiab tsiaj txhu cuam tshuam los ntawm tshav kub?
Thaum kub tshaj 50 degree (122 degree F), tib neeg daim tawv nqaij tuaj yeem pib hlawv. Cov khoom ntawm 40 degree (104 degree F) lossis siab dua yuav hnov "kub" rau qhov kov. Nco ntsoov tias qee qhov LED strips, zoo li cov los ntawm Waveform Teeb pom kev zoo, tuaj yeem ncav cuag qhov kub thiab txias siab dhau los tiv thaiv qhov kub thiab txias. Txawm hais tias feem ntau ntawm LED sawb daim ntawv thov tsis cuam tshuam rau ntawm daim tawv nqaij ntawm daim tawv nqaij, yog tias koj qhov project tshwj xeeb ua, koj yuav tsum tau ua kev ntsuas kev nyab xeeb kom paub tseeb tias LED strips tsis yooj yim rau tib neeg lossis tsiaj.
2) Puas yog cov cua sov puas yuav ua rau cov LEDs, qhov chaw, lossis lub rooj sib tham?
Feem ntau cov LEDs, qhov chaw, thiab LED strip circuits yog tsim los ua haujlwm ntawm qhov kub ntawm 185 degree F (85 degree) lossis siab dua yam tsis muaj kev cuam tshuam tsis zoo rau lawv lub neej kev cia siab, kev cia siab, lossis kev ua haujlwm. Yog li ntawd, yuav luag tsis muaj LED strips yuav ncav cuag qhov kub thiab txias, thiab yuav tsum tsis txhob muaj ntau yam kev txhawj xeeb txog seb LED sawb puas yuav ua haujlwm tsis zoo los ntawm kev kub ntxhov, tshwj tsis yog cov khoom tsim tsis zoo lossis muaj teeb meem, nrog rau cov uas muab tso rau hauv qhov chaw hnyav uas qhov kub thiab txias ambient kub heev.
Nco ntsoov tias 185 degree F (85 degree) qhov kub siab tshaj plaws yog qhov siab tshaj 100 degree F (40 degree) lossis siab dua qhov pib uas cov neeg feem coob xav tias yog "kub dhau" kov. Yog li ntawd, txawm tias ib qho LED sawb yuav "xav" kub rau qhov kov, qhov tseeb qhov kub thiab txias feem ntau nyob twj ywm hauv qab ntawm qhov pib los tiv thaiv kev puas tsuaj.
3) Puas yuav yaj los yog hluav taws kub?
Txawm hais tias txawv heev, qhov tawg ntawm LED sawb teeb yuav tsis tshua ncav cuag qhov kub thiab txias uas siab tshaj nws cov kev khiav hauj lwm ntau yam. Siv cov teeb pom kev zoo LED sawb teeb uas tau tsim nrog cov khoom zoo heev thiab nyob rau hauv kev saib xyuas nruj yog txoj hauv kev zoo tshaj plaws los txo qhov kev pheej hmoo no vim tias lawv tsis tshua muaj kev tsim khoom thiab tsim teeb meem uas yuav ua rau muaj kev kub ntxhov.
Kev siv cov LED sawb teeb, uas yog tsim kom muaj kev ruaj ntseg txawm tias muaj kev ua haujlwm tsis zoo, yog lwm txoj hauv kev kom txo tau kev nyab xeeb. Ua kom lub Circuit Courtboard muaj qhov ntsuas hluav taws xob. Qhov no yog kev ceev faj tus qauv, tab sis tu siab, cov neeg tsim khoom ntawm cov khoom kim heev tsis tas yuav ua raws li nws. Lub Circuit Court yuav tsis nquag ntes hluav taws txawm tias muaj cov khoom siv lossis cov nplaim hluav taws raws li UL 94 tus qauv.
Siv cov khoom siv hluav taws xob uas tau lees paub hauv chav kawm 2 thiab LED strips, uas muaj tag nrho lub zog txwv ntawm 96W, yuav yog lwm qhov kev ceev faj. Cov khoom no tuaj yeem pab txo qis kev pheej hmoo ntawm hluav taws kub thiab lwm yam kev puas tsuaj los ntawm kev txwv tag nrho cov cua sov thiab lub zog uas muab tso rau hauv ib qho system.
