LED vs Halogen Lub Teeb: Dab tsi yog Qhov Zoo Tshaj?

Ob lub LED (Lub Teeb Emitting Diode) thiab halogen lub teeb qhov muag teev yog cov qauv teeb pom kev zoo siv rau sab nraum zoov, kev lag luam, thiab thaj chaw teeb pom kev zoo, thiab lwm yam kev siv.

LED teeb yog tsim los ntawm semiconductor chips uas tsim lub teeb thaum muaj hluav taws xob tam sim no ntws los ntawm lawv, thaum lub teeb halogen muaj tungsten filament encased nyob rau hauv ib lub hnab ntawv me me quartz uas muaj roj halogen.

Qhov sib txawv tseem ceeb ntawm halogen thiab LED (lub teeb-emitting diode) teeb yuav tau tham hauv nqe lus no.

Cov neeg nyeem yuav xaiv ntawm LED thiab halogen teeb pom kev zoo rau ntau yam kev siv los ntawm kev paub txog cov kev sib txawv no.

Vim lawv txoj kev sib txawv ntawm kev tsim lub teeb, LED teeb siv ntau lub zog tsawg duahalogen teeb.

Vim tias nws cov filament tsis zoo-raws li thev naus laus zis, halogen teeb tsim hluav taws xob ntau dua li lub teeb, whereas LEDs hloov feem pua ntawm hluav taws xob ntau dua rau hauv lub teeb pom kev.

Lub Tsev Haujlwm Saib Xyuas Kev Ruaj Ntseg Hauv Teb Chaws Asmeskas tau hais tias LED qhov muag teev tuaj yeem txuag tau txog 80% ntawm kev siv hluav taws xob thaum piv rau cov teeb pom kev zoo halogen incandescent.

Yog li ntawd lawv yog ib qho kev xaiv zoo tshaj plaws rau kev siv teeb pom kev zoo.

Wattage LED teeb tuaj yeem tsim teeb pom kev zoo ntawm qib sib npaug lossis ntau dua li cov teeb halogen, txawm hais tias lawv feem ntau muaj qhov ntsuas qis dua.

Qhov no yog vim qhov tseeb tias LEDs siv lub zog tsawg dua thiab ua haujlwm ntawm qhov kub thiab txias los tsim lub teeb.

Qhov ua tau zoo ntawm LED thev naus laus zis hauv cov ntsiab lus ntawm watts tau pom los ntawm qhov tseeb tias 10-watt LED teeb tuaj yeem tsim qhov ci ci tib yam li 60-watt halogen teeb.

LED teeb feem ntau kav ntev txog 25 npaug ntev dua li lub teeb halogen, uas yog qhov sib txawv tseem ceeb hauv kev ua neej ntev.

Qhov no feem ntau yog vim tias cov teeb ci LED tsis muaj qhov muag muag zoo li cov teeb halogen ua, uas tuaj yeem tawg lossis tawg nrog lub sijhawm.

LED teeb qhov muag teev tuaj yeem ua haujlwm rau kaum tawm txhiab teev, uas txo qis qhov xav tau kev hloov lub teeb ntau zaus thiab cov nqi kho mob ntsig txog.

Thaum siv, halogen teeb ua kom muaj cua sov ntau, tab sis LED qhov muag teeb ua kom tsawg.

Qhov no yog vim qhov tseeb tias LEDs tsim lub teeb los ntawm cov txheej txheem hu ua electroluminescence, uas ncaj qha hloov hluav taws xob hluav taws xob rau hauv lub teeb yam tsis muaj cua sov ntxiv.

Halogen teeb, ntawm qhov tod tes, tsim lub teeb los ntawm kev tiv thaiv cua sov ntawm tungsten filament.

Yog li ntawd, ib qho tseem ceeb ntawm cov hluav taws xob hluav taws xob tau hloov mus rau hauv thermal zog.

Whereas halogen teeb yuav tsum tau tshwj xeeb dimmer hloov mus rau dim, LED teeb yog ib txwm dimmable, ua rau cov neeg siv hloov lub brightness theem kom haum lawv saj.

Qhov no yog vim LEDs 's du thiab zoo dimming muaj peev xwm, uas tso cai rau lawv hloov cov teeb pom kev zoo uas lawv tawm los ntawm qhov sib txawv ntawm qhov tam sim no ntws los ntawm lawv.

Piv txwv li, thaum lub teeb halogen siv nrog mismatched dimmer keyboards, lawv yuav flicker los yog ua tsis tau zoo thaum dimmed.

Tshooj lus no tshawb txog qhov sib txheeb qhov ci ci ntawm LED thiabhalogen teeb, saib tej yam xws li sib xws, xim rendering, lub teeb dispersion, thiab luminous efficiency.

Koj tuaj yeem kawm paub ntau ntxiv txog txhua qhov teeb pom kev zoo ntawm cov teeb pom kev zoo thiab qhov tsim nyog rau ntau yam teeb pom kev zoo los ntawm kev hais txog qhov txawv ntawm qhov ci ntawm lawv.

Piv nrog rau cov teeb halogen, LED teeb muaj qhov ua tau zoo luminous, uas txhais tau hais tias lawv emit ntau lumens ntawm lub teeb ib watt ntawm lub zog siv.

Qhov no tau piav qhia los ntawm LED thev naus laus zis qhov tshwj xeeb muaj peev xwm hloov hluav taws xob hluav taws xob mus rau qhov pom kev pom.

Halogen teeb muaj qhov ua tau zoo ntawm 10 mus rau 35 lumens ib watt, tab sis LED luminaires feem ntau muaj 70 mus rau 120 lumens ib watt, raws li Illuminating Engineering Society (IES).

Thaum lub teeb halogen tso lub teeb nyob rau hauv tag nrho cov lus qhia, LED teeb feem ntau muaj ntau lub teeb qhia kev faib tawm, muab cov neeg siv ntau tswj kev taw qhia thiab qhov siab ntawm lub teeb beam.

Rau cov ntawv thov xws li cov teeb pom kev zoo lossis cov teeb pom kev zoo, qhov chaw pom tseeb ntawm cov cheeb tsam tshwj xeeb yog qhov tsim nyog, LED teeb pom kev zoo yog qhov zoo.

Xim Rendering LED teeb feem ntau yog qhov tseeb thiab muaj zog ntawm cov xim vim tias lawv muaj ntau dua Xim Rendering Index (CRI) dua li lub teeb halogen.

Cov txiaj ntsig CRI siab dua qhia tias muaj peev xwm ua kom muaj xim ntau dua. Lub CRI piv lub teeb ci xim rendering raug rau cov hnub ci ntuj.

For settings like art galleries, shop displays, and photography studios where color accuracy is crucial, LED lights with high CRI values (>90) raug pom zoo.
