Ua ntej coj koj los txiav txim siab teeb pom kev zoo, peb xav tias nws tseem ceeb heev kom nkag siab qhov txawv ntawm LED teeb thiab cov teeb halogen txheem.
LED: nws siv lub teeb-emitting diodes kom emit lub teeb. Lub hauv paus ntsiab lus ntawm lub teeb emission yog qhov ncaj qha hloov hluav taws xob rau lub teeb, uas yog lub teeb txias.
Halogen: nws siv tungsten filaments kom emit lub teeb. Lub hauv paus ntsiab lus ntawm luminescence yog hloov dua siab tshiab ntawm hluav taws xob-kub-lub teeb lub zog, uas yog lub teeb ci incandescent.
Kev siv hluav taws xob & Kev siv hluav taws xob
Piv nrog LED, halogens siv zog ntau dua. Yog tias koj xav ntsuas cov teeb pom kev zoo los ntawm txhua qhov teeb pom kev zoo, ces kev hais lus, lub teeb halogen yuav tsim 2,700 lumens, uas txhais tau tias yog 30 watts.
Ntawm qhov tod tes, thaum siv tib lub zog 30 watts, LED teeb lub teeb yuav tsim txog 4,500 lumens. Thaum lub wattage siv zoo ib yam, cov lumens uas tsim los ntawm LED teeb yuav siab dua li ntawm lub teeb halogen, yog li cov teeb pom kev zoo ntawm LED teeb yuav siab dua li ntawm lub teeb halogen; Thaum cov lumens xav tau zoo ib yam, lub wattage ntawm LED teeb yuav qis dua li ntawm lub teeb halogen, yog li lub zog noj ntawm LED teeb yuav qis dua li ntawm lub teeb halogen.
Kev ua neej nyob
LED teeb muaj lub neej nyob ruaj khov, tuaj yeem nce 50,000--80,000 teev. Qhov ntawd yog sib npaug rau ib ncig ntawm 13 xyoo.
Halogen teeb tau cuam tshuam los ntawm nws cov txheej txheem tsim khoom, lub neej expectancy yog qis dua li ntawm LEDs, tsuas yog 3500-3600 teev, uas yog sib npaug rau 1 xyoo.
CCT (xim kub) los yog CRI (Color Rendering Index)
Lub CRI ntawm Halogen teeb yog 100, thiab nws zoo ib yam rau lub teeb nruab hnub. Nrog rau kev txhim kho txuas ntxiv ntawm thev naus laus zis, CRI ntu ntawm LED yuav raug txhim kho tsis tu ncua, thiab twb tau siab CRI thiab siab luminous efficiency teeb hlaws uas tuaj yeem ua tiav ntau dua 95. Feem ntau, CRI ntawm LED yog nyob ib ncig ntawm 80, thiab uas muaj mus txog peb cov kev xav tau rau cov teeb pom kev zoo.
Qhov tseeb, qhov tseem ceeb yog CCT, tsis yog CRI. Thaum CRI nce mus txog ib qho nqi, nws tuaj yeem ua tau raws li peb cov kev cai rau cov teeb. Tab sis CCT yuav cuam tshuam rau lub teeb ncaj qha. Halogen teeb feem ntau tsuas muaj ib qho xim kub, xim kub yog li 2700K, thiab lub teeb yog daj. LED tuaj yeem xaiv ntawm qhov xav tau hauv 3000-6500K. Hauv kev sib piv, LEDs tau xaiv ntau dua thiab hloov tau yooj yim dua.
Lub teeb faib
Lub teeb faib ntawm lub teeb feem ntau yog nyob rau hauv nws beam kaum sab xis. Qhov loj dua lub kaum sab xis ntawm lub teeb nrog tib lub zog, qhov me dua qhov nruab nrab lub teeb siv, thiab qhov loj dua qhov pom ntawm qhov chaw, qhov chaw yuav softer; ntawm qhov tsis sib xws, qhov me me ntawm lub nqaj kaum sab xis, qhov loj dua qhov nruab nrab lub teeb siv, tab sis qhov me me ntawm qhov pom ntawm qhov pom, qhov chaw teeb pom kev nyuaj dua.
Lub teeb faib lub kaum sab xis ntawm lub teeb halogen yog qhov me me, thiab qhov sib txawv yog 10 degrees, 24 degrees, thiab 38 degrees. Lub teeb LED siv lub lens tswj lub teeb beam lub kaum sab xis, yog li nws lub teeb faib tau zoo xaiv. Los ntawm 15 degrees mus rau 120 degrees, muaj ntau txoj kev xaiv.
