Kev siv LED teeb pom kev zoo yog loj hlob nyob rau hauv muaj koob meej. Txawm li cas los xij, qee tsev neeg tseem tsis tau txiav txim siab txog kev hloov ntawm lub teeb rau LED. Koj puas suav nrog lawv? Los yog tej zaum koj tau xaiv hloov mus rau LED teeb tab sis tsis paub meej tias nws muaj dab tsi.
Tsis txhob txhawj, txawm li cas los xij. Kab lus no piav qhia vim li cas hloov mus rau LED teeb pom kev zoo yog qhov kev txiav txim siab zoo. Tsis tas li ntawd, cov ntsiab lus ntawm ntau lo lus hais txog LED teeb pom kev zoo yuav raug them. Peb tseem yuav hais txog qee cov lus nug uas nquag nug los ntawm cov neeg siv khoom thawj zaug hauv ntu kawg.
Yog li cia peb mus.
Vim li cas thiaj siv LED hloov?
Lawv muaj lub neej ntev dua thiab tsis muaj mercury ntxiv rau kev siv hluav taws xob ntau dua li ob qho kev xaiv CFL thiab incandescent, uas ua rau muaj kev txuag hluav taws xob tseem ceeb rau koj. Tsis tas li ntawd, LED teeb muaj ntau yam kev xaiv rau qhov ci thiab lub teeb xim (txias vs. sov). Qhov kawg tab sis tsis tsawg kawg, LED qhov muag teev muaj nyob rau hauv ntau hom, ntau thiab tsawg, thiab cov duab.
Terminology
Thaum siv cov teeb pom kev zoo ib txwm muaj, txhua yam tseem ceeb yog qhov wattage, lub hauv paus loj, thiab daim ntawv ntawm lub teeb. Txawm li cas los xij, LED teeb qhov muag teev yog qhov txawv ntawm qhov no.
Cov 4 lub tswv yim no yuav tsum to taub kom meej ua ntej yuav khoom LED teeb:
Brightness
zoo li lub teeb
Xim fidelity
Teeb pom kev zoo
Brightness yog sib npaug rau wattage, txoj cai? Tsis yog. Cov tib neeg feem ntau yuam kev xav tias wattage thiab brightness sib npaug. Txawm hais tias muaj kev sib raug zoo ntawm ob qho tib si hauv cov teeb pom kev zoo, cov khoom sib txawv nrog cov teeb ci LED. Thiab yog vim li cas thiaj li yog qhov kawg siv lub zog tsawg dua li cov teeb ci. Qhov no ua rau wattage-raws li kev sib piv ntawm qhov ci ntawm LED teeb qhov muag tsis pom kev.
Qhov tsuas yog qhov koj yuav tsum tau coj mus rau hauv tus account los txiav txim siab npaum li cas lub teeb lub teeb LED teeb emits yog lumens. Nws qhia meej qhov ci ci ntawm qhov chaw teeb pom kev zoo thiab ua haujlwm raws li chav ntsuas rau qhov ci. Rau kev sib piv, lub teeb incandescent uas siv 60 watts feem ntau tsim 800 lumens.
Luminous tsos
Kelvin nplai yog lwm qhov tseem ceeb tshaj plaws uas koj yuav tsum paub txog. Nws ua haujlwm raws li qhov ntsuas ntsuas rau lub teeb qhov sib txheeb xim kub (CCT). Txheeb xyuas lub teeb ci LED lub teeb qhov nqi kelvin los txiav txim seb nws tawm lub teeb txias dua lossis sov dua. Lub teeb yuav txias dua thiab xiav ntau dua tus lej. Hloov pauv, cov lej qis dua muaj feem cuam tshuam nrog lub teeb pom kev sov dua thiab pom tseeb dua.
Xim raug
Lub peev xwm ntawm lub teeb ci kom pom tseeb cov khoom 'xim yog nyob ntawm nws cov xim raug. Yog raug txhais raws li nyob rau hauv relation mus rau lub hnub thaum peb hais nws.
Rau qhov no, Xim Rendering Index (CRI) yog ua haujlwm. Nws muaj qhov ntsuas 0 txog 100. Muab hais tias cov teeb pom kev zoo no tsim lub teeb sib npaug sib npaug, CRI ntawm 90 thiab siab dua yog suav tias yog qhov zoo tshaj plaws. Peb ntawm LiquidLEDs siv zog los muab koj cov kev paub zoo tshaj plaws ntawm LED, yog li feem ntau ntawm peb lub teeb ci LED muaj CRI 90 ntxiv.
Dimming
Dimming ua pov thawj tias yog ib qho tseem ceeb ntawm kev ua haujlwm thaum nws los txog rau kev ua haujlwm thiab teeb pom kev zoo. Koj tuaj yeem hloov qhov ci ntsa iab kom ua tiav qhov ci ntsa iab zoo tshaj plaws uas xav tau rau kev ua haujlwm lossis kom lav qhov teeb pom kev zoo haum rau lub siab xav thiab ib puag ncig. Dimmable LED teeb pom kev zoo tuaj yeem pab koj txuag hluav taws xob ntau dua.
Thaum feem ntau ntawm LED teeb muaj tam sim no tuaj yeem dim tau, tsis yog txhua tus laus dimmers yuav ua haujlwm tsis zoo nrog lawv. Koj yuav tsum nco ntsoov peb yam no thaum siv cov dimmers qub nrog cov teeb pom kev niaj hnub LED:
Qee cov dimmers qub yuav tsis sib haum nrog cov teeb pom kev tshiab LED. Yog li ntawd, xyuas kom meej tias lub teeb yuav ua hauj lwm nrog koj tam sim no dimmer ua ntej yuav khoom. Feem ntau (yog tias tsis yog tag nrho) cov tuam txhab muab cov npe sib xws uas suav nrog cov npe ntawm txhua hom dimmer thiab cov qauv uas tau kuaj xyuas thiab sib haum nrog LED teeb.
Ua raws li cov chaw tsim khoom cov lus qhia yog xav kom tau txais qhov zoo tshaj plaws illumination kev.
Ib qho dimmer tsis tu ncua tuaj yeem lossis tsis ua haujlwm zoo nrog lub teeb ci LED, txawm tias lawv sib xws. Koj tuaj yeem muaj teeb meem xws li flickering lossis tsis txaus dimming theem yog tias qhov no tshwm sim. Piv txwv li, LED qhov muag teev siv lub zog tsawg dua li cov teeb incandescent. Qhov laj thawj tseem ceeb ntawm vim li cas LED qhov muag teev qee zaus tsis ua haujlwm zoo nrog vintage dimmers ua rau qhov muag teeb yog qhov no.
Nws yog ib qho tseem ceeb uas yuav tau nqis peev pab rau cov dimmers tsis ntev los no uas yog tsim rau cov qij taws teeb thaum hloov mus rau lawv.
