Dab tsi yog LED Sawb Teeb?
LED sawb teeb yog cov qauv tshiab thiab ntau yam ntawm cov teeb pom kev zoo.Muaj ntau ntau yam sib txawv thiab kev zam, tab sis rau feem ntau, lawv muaj cov yam ntxwv hauv qab no:
● Muaj ntau tus neeg LED emitters mounted rau ib tug nqaim, hloov tau yooj yim circuit board
● Ua haujlwm ntawm qhov hluav taws xob DC tsawg
● Muaj nyob rau hauv ntau yam ruaj khov thiab hloov pauv xim thiab ci ntsa iab
● Nkoj nyob rau hauv ib lub reel ntev (feem ntau yog 16 feet / 5 meters), tuaj yeem txiav kom ntev, thiab suav nrog ob-sided nplaum rau mounting
Anatomy ntawm LED sawb
Lub teeb ci LED feem ntau yog ib nrab nti (10-12 hli) hauv qhov dav, thiab mus txog 16 feet (5 meters) lossis ntev dua.Lawv tuaj yeem txiav mus rau qhov ntev tshwj xeeb uas tsuas yog siv ob lub txiab raws cov kab txiav, nyob txhua 1-2 ntiv tes.
Cov LEDs ib leeg yog mounted raws lub strip, feem ntau ntawm qhov ntom ntawm 18-36 LEDs ib ko taw (60-120 ib meter).Lub teeb xim thiab zoo ntawm tus kheej LEDs txiav txim siab tag nrho lub teeb xim thiab zoo ntawm LED sawb.
Sab nraub qaum ntawm LED sawb suav nrog pre-applied ob-sided nplaum nplaum.Tsuas tev tawm lub liner, thiab mount lub LED sawb mus rau txhua qhov chaw.Vim hais tias lub Circuit Court yog tsim los hloov tau, LED strips tuaj yeem ntsia tau rau ntawm qhov nkhaus thiab tsis sib xws.
Txiav txim siab LED Sawb Brightness
Qhov ci ntsa iab ntawm LED strips yog txiav txim siab siv qhov ntsuaslumens.Tsis zoo li cov qij incandescent, txawv LED strips tuaj yeem muaj ntau theem ntawm kev ua haujlwm, yog li kev ntsuas wattage tsis yog ib txwm muaj txiaj ntsig hauv kev txiav txim siab lub teeb pom kev zoo.
LED strip brightness feem ntau piav qhia hauv lumens ib ko taw (los yog meter).Ib qho zoo LED sawb yuav tsum muab tsawg kawg yog 450 lumens ib ko taw (1500 lumens ib meter), uas muab kwv yees li ntawm tib lub teeb tso zis ib ko taw raws li ib txwm T8 teeb fluorescent.(Piv txwv li 4-ft T8 fluorescent = 4-ft ntawm LED sawb = 1800 lumens).
LED strip brightness feem ntau yog txiav txim los ntawm peb yam:
● Lub teeb tso zis thiab efficiency ib LED emitter
● Tus naj npawb ntawm LEDs ib ko taw
● Lub zog kos ntawm LED sawb ib ko taw
LED sawb teeb tsis muaj qhov ci ci hauv lumens yog tus chij liab.Koj tseem yuav xav saib xyuas cov nqi qis LED strips uas thov qhov ci ci siab, vim tias lawv tuaj yeem ua rau cov LEDs dhau mus rau qhov ua tsis tiav ntxov.
LED Ceev & Fais Fab Draw
Koj tuaj yeem hla ntau lub npe LED emitter xws li 2835, 3528, 5050 lossis 5730. Tsis txhob txhawj ntau dhau ntawm qhov no, vim qhov tseem ceeb tshaj plaws hauv LED sawb yog tus naj npawb ntawm LEDs ib ko taw, thiab lub zog kos ib ko taw.
LED ntom ntom yog qhov tseem ceeb hauv kev txiav txim siab qhov kev ncua deb ntawm LEDs (pitch) thiab seb puas yuav pom cov hotspots thiab tsaus nti ntawm LED emitters.Qhov ceev dua ntawm 36 LEDs ib ko taw (120 LEDs ib meter) feem ntau yuav muab qhov zoo tshaj plaws, feem ntau cov teeb pom kev zoo sib npaug.LED emitters yog cov khoom kim tshaj plaws ntawm LED sawb kev tsim khoom, yog li nco ntsoov suav rau LED qhov sib txawv ntawm qhov sib txawv thaum sib piv cov nqi LED sawb.
Tom ntej no, xav txog LED sawb teeb lub zog kos ib ko taw.Lub zog kos qhia peb lub zog uas lub kaw lus yuav siv, yog li qhov no yog qhov tseem ceeb los txiav txim siab koj cov nqi hluav taws xob thiab cov khoom siv hluav taws xob (saib hauv qab).Ib qho zoo LED sawb yuav tsum muaj peev xwm muab 4 watts ib ko taw lossis ntau dua (15 W / meter).
Thaum kawg, ua ib qho kev ntsuam xyuas sai los txiav txim siab seb tus neeg LEDs puas tau dhau los ntawm kev faib cov wattage ib ko taw los ntawm LED ntom ntom ib ko taw.Rau cov khoom lag luam LED sawb, nws feem ntau yog qhov cim zoo yog tias cov LEDs tsis tau tsav ntawm ntau tshaj 0.2 watts txhua.
LED Sawb Xim xaiv: Dawb
LED sawb teeb muaj nyob rau hauv ntau yam ntxoov ntawm dawb los yog xim.Feem ntau, lub teeb dawb yog qhov kev xaiv zoo tshaj plaws thiab nrov tshaj plaws rau kev siv teeb pom kev hauv tsev.
Hauv kev piav qhia txog qhov sib txawv ntawm qhov ntxoov ntxoo thiab qhov zoo ntawm cov xim dawb, xim kub (CCT) thiab xim rendering Performance index (CRI) yog ob qhov kev ntsuas uas tseem ceeb uas yuav tsum nco ntsoov.
Xim kub yog qhov ntsuas ntawm qhov "sov" lossis "txias" lub teeb xim li cas.Lub ci ntsa iab ntawm lub teeb ci ib txwm muaj xim kub (2700K), thaum lub ntsej muag ci, ci dawb ntawm lub hnub ci ntuj muaj xim kub (6500K).
Xim rendering yog ib qho kev ntsuas ntawm qhov tseeb xim tshwm nyob rau hauv lub teeb qhov chaw.Nyob rau hauv qis qis CRI LED sawb, xim yuav tshwm sim distorted, ntxuav tawm, los yog indistinguishable.Cov khoom lag luam siab CRI LED muab lub teeb uas tso cai rau cov khoom tshwm sim raws li lawv xav tau nyob rau hauv lub teeb pom kev zoo xws li lub teeb halogen, lossis hnub ci ntuj.Tsis tas li nrhiav lub teeb pom kev zoo tus nqi R9, uas muab cov ntaub ntawv ntxiv txog yuav ua li cas cov xim liab ua tiav.
LED Sawb Xim xaiv: Tsau thiab hloov pauv xim
Qee zaum, tej zaum koj yuav xav tau ib qho punchy, saturated xim nyhuv.Rau cov xwm txheej no, cov xim LED strips tuaj yeem muab cov lus pom zoo thiab ua yeeb yam teeb pom kev zoo.Cov xim thoob plaws tag nrho cov spectrum pom muaj - violet, xiav, ntsuab, amber, liab - thiab txawm ultraviolet los yog infrared.
Muaj ob hom xim LED strips: tsau ib xim, thiab xim hloov.Cov xim ruaj khov LED sawb tawm tsuas yog ib qho xim, thiab txoj haujlwm ua haujlwm zoo ib yam li cov kab dawb LED peb tau tham saum toj no.Ib qho xim-hloov LED sawb muaj ntau cov xim raws ntawm ib qho LED sawb.Hom yooj yim tshaj plaws yuav suav nrog cov kab liab, ntsuab thiab xiav (RGB), tso cai rau koj los sib xyaw cov xim sib txawv ntawm cov yoov kom ua tiav txhua yam xim.
Qee qhov yuav tso cai rau kev tswj hwm qhov kub ntawm cov xim dawb lossis txawm tias ob qho tib si xim kub thiab RGB hues.
Input Voltage & Fais fab mov
LED strips feem ntau yog teeb tsa ua haujlwm ntawm 12V lossis 24V DC.Thaum khiav tawm ntawm tus qauv mains muab lub zog hluav taws xob (xws li lub qhov hluav taws xob hauv tsev) ntawm 120/240V AC, lub zog yuav tsum tau hloov mus rau qhov tsim nyog qis voltage DC teeb liab.Qhov no yog feem ntau thiab tsuas yog ua tiav siv DC fais fab mov.
Xyuas kom tseeb tias koj lub hwj chim muaj txausmuaj peev xwmlos txhawb cov LED strips.Txhua lub DC fais fab mov yuav sau nws qhov siab tshaj plaws tam sim no (hauv Amps) lossis lub zog (hauv Watts).Txiav txim siab tag nrho lub zog kos ntawm LED sawb siv cov qauv hauv qab no:
● Fais fab = LED zog (ib ft) x LED sawb ntev (hauv ft)
Piv txwv scenario txuas 5 ft ntawm LED sawb qhov twg LED sawb fais fab noj yog 4 Watts ib ko taw:
● Fais fab = 4 Watts ib ft x 5 ft =20 Watts
Lub zog kos ib ko taw (los yog ' meter ') yog yuav luag ib txwm teev nyob rau hauv daim ntawv qhia LED strip.
Tsis paub meej tias koj yuav tsum xaiv ntawm 12V thiab 24V?Tag nrho lwm yam sib npaug, 24V feem ntau yog koj thawj koom ruam zoo tshaj.
