Ua ntej, xaiv lumen / watt siab yaorong LED teeb pom kev zoo fixtures
Luminous flux, uas yog tag nrho cov nyiaj pom ntawm lub teeb emitted los ntawm lub teeb qhov chaw nyob rau hauv chav tsev lub sij hawm, chav tsev: lumens (Lm). luminescent efficiency yog hais txog lub teeb lub zog (feem ntau hu ua luminous flux) emitted los ntawm lub teeb qhov chaw ib W ntawm hluav taws xob fais fab. Unit: lumen/watt (Lm/W). Nws yog hais txog qhov ua tau zoo ntawm cov teeb pom kev zoo ntawm lub teeb ua tiav LED txoj kev teeb.Raws li qhov ntsuas hluav taws xob, tag nrho cov luminous flux tawm los ntawm LED teeb muab faib los ntawm tag nrho lub zog noj ntawm LED teeb, uas yog, kev ua haujlwm zoo ntawm LED teeb. , qhia los ntawm lumens / watt, tus nqi siab dua, qhov zoo ntawm cov teeb pom kev zoo, kev txuag hluav taws xob ntau dua.Raws li tib lub zog, cov teeb thiab cov teeb ci nrog kev ua haujlwm siab luminous, loj luminous flux, muaj zog thiab txuag hluav taws xob ntau! Lub 3W LED teeb yog siab dua 18W CFLs.Thiab qhov ntawd yog li yim npaug ntawm qhov piv ntawm 40W incandescent noob.
Ob, xaiv cov xim rendering Performance index ntawm cov khoom siab
Xim rendering yog hais txog cov xim ntawm cov khoom nyob rau hauv lub teeb irradiation thiab qhov tseeb xim ntawm qhov degree ntawm qhov sib thooj.Qhov loj dua qhov xim rendering Performance index "Ra" tus nqi yog, qhov ze ntawm cov xim ntawm cov khoom yog rau cov xim tiag tiag.Nws yog feem ntau ntseeg hais tias: 80 ~ 100, zoo heev xim rendering; 50 ~ 79, xim rendering yog dav: <50, xim rendering yog pluag.yaorong LED teeb fixtures nrog siab xim rendering Performance index yuav tsum tau xaiv.
Thib peb, kev xaiv lub teeb ci xim kub raws li tus kheej nyiam
Nws chav xim kub yog Kelvin (K), xim kub ntawm lub teeb liab qhov chaw yog li 800K ~ 900K, xim kub ntawm cov xim daj thiab dawb lub teeb yog li 3000K, xim kub ntawm lub teeb dawb yog li 5500K , xim kub ntawm lub teeb xiav lub teeb yog li ntawm 8000K ~ 12000K.Qhov kev xaiv ntawm lub teeb ci xim kub nyob ntawm txhua tus neeg nyiam, qee cov neeg nyiam xim sov, yog li 3000K xim kub teeb yog haum rau nws, xws li hnub ci xim ntawm 5000K ~ 6500K xim kub lub teeb tuaj yeem ua tau raws li qhov yuav tsum tau ua, zoo li cov xim txias, xaiv 8000K ~ 12000K yaorong LED teeb pom kev zoo.
