1. Xaiv LED teeb pom kev zoo nrog lumens / watt qhov siab
Luminous flux, uas yog, tag nrho cov pom lub teeb emitted los ntawm lub teeb qhov chaw ib lub sij hawm, nyob rau hauv lumens (Lm). Luminous efficiency, uas yog, lub teeb lub zog (feem ntau hu ua luminous flux) generated los ntawm lub teeb qhov chaw ib W ntawm hluav taws xob fais fab, chav tsev: lumens / watt (Lm / w)
Lub luminous efficiency ntawm LED teeb yog hais txog lub luminous efficiency ntawm ib tug tiav lawm LED txoj kev teeb. Raws li qhov ntsuas hluav taws xob, tag nrho cov luminous flux tawm los ntawm LED teeb yog muab faib los ntawm tag nrho lub zog noj ntawm LED teeb, uas yog tag nrho cov luminous efficiency ntawm LED teeb, qhia nyob rau hauv lumens / watt. Qhov siab dua tus nqi, lub zog txuag cov nyhuv ntawm lub teeb. Qhov zoo dua, lub zog txuag ntau dua. Nyob rau hauv tib lub hwj chim, lub teeb nrog high luminous efficiency muaj loj luminous flux, uas yog brighter thiab ntau zog-txuag! Lub 3W LED qhov muag teev yog siab tshaj 18W lub zog txuag teeb. Thiab qhov piv yog kwv yees li 8 npaug ntawm 40W incandescent teeb.
2. Xaiv cov khoom uas muaj cov xim rendering siab
Xim rendering yog hais txog qhov ze ntawm cov xim ntawm ib yam khoom nyob rau hauv lub illumination ntawm lub teeb mus rau qhov tseeb xim. Qhov loj dua qhov xim rendering Performance index "Ra" tus nqi, qhov ze ntawm cov xim ntawm cov khoom yog rau cov xim tiag. Feem ntau suav hais tias: 80-100, zoo heev xim rendering; 50-79, general xim rendering:<50, poor="" color="" rendering.="" led="" lighting="" fixtures="" with="" high="" color="" rendering="" index="" should="" be="">
3. Cov xim kub ntawm lub teeb ci yog xaiv raws li tus kheej nyiam
Chav tsev ntawm cov xim kub yog Kelvin (K), xim kub ntawm lub teeb liab qhov chaw yog li 800K-900K, xim kub ntawm daj-dawb lub teeb yog li ntawm 3000K, xim kub ntawm lub teeb dawb yog hais txog 5500K, thiab xim kub ntawm lub teeb xiav lub teeb yog 8000K-12000K. Cov xim kub ntawm lub teeb ci yog xaiv raws li txhua tus neeg nyiam. Qee cov neeg nyiam cov xim sov, yog li lub teeb uas muaj xim kub ntawm ib ncig ntawm 3000K yog qhov haum rau nws. Cov uas nyiam hnub ci xim tuaj yeem ua tau raws li lawv cov kev xav tau nrog cov xim kub ntawm 5000K-6500K. Cov uas nyiam cov xim txias tuaj yeem xaiv 8000K ~ 12000K LED teeb pom kev zoo.
4. Qhov me me ntawm qhov luminous lwj, qhov zoo dua, qhov loj dua qhov luminous flux, qhov zoo dua
Lub teeb lwj: Lub luminous flux ntawm lub teeb ci maj mam txo qis rau cov txheej txheem ntawm kev qaug zog, uas yog, cov txheej txheem ntawm maj mam txo qis ntawm qhov ci ntawm lub teeb tom qab siv lub sijhawm.
Luminous flux txij nkawm tus nqi: lub teeb yog teeb nyob rau hauv cov xwm txheej, lub luminous flux ntsuas 100 teev tom qab lub teeb yog lit raws li tus nqi pib, thiab qhov piv ntawm qhov ntsuas luminous flux tom qab 2000 teev ntawm re-ignition, qhia raws li feem pua ( tsis tsawg tshaj li 80 feem pua), Raws li lub tswv yim teeb pom kev zoo los ntsuas lub teeb lwj.
Cov lus piav qhia nrov yog tias qhov ci ntawm lub teeb yuav txo qis tom qab siv nws rau lub sijhawm. Rau qhov sib txawv ntawm cov teeb pom kev zoo, qhov siab dua qhov luminous flux tu tus nqi nyob rau tib lub sij hawm teev, qhov me me lub teeb attenuation ntawm lub teeb qhov chaw.
