Illuminance xam xam Brightness xam
Qhov tseeb illuminance xam yog ib qho teeb meem nyuaj heev. Nws lub ntsiab yog kev hloov ntawm luminous flux. Nws suav nrog kev suav cov ntsiab lus teeb pom kev zoo, suav cov teeb pom kev ntawm qhov chaw, suav cov teeb pom kev ncaj qha, suav cov teeb pom kev tsis ncaj, thiab lwm yam.

Ntawm no peb tsom mus rau kev suav ntawm qhov nruab nrab illuminance. Lub tswv yim ntawm kev saib xyuas zoo yuav raug siv nyob rau hauv qhov nruab nrab illuminance. Lub tswv yim no kuj yooj yim to taub, uas yog, nrog kev siv cov teeb, lawv cov luminous flux yuav maj mam txo. Qib ntawm qhov kev saib xyuas no feem ntau cuam tshuam nrog cov hauv qab no.

Lub degree ntawm lub teeb lwj ntawm lub teeb pom kev zoo, vim hais tias nyob rau hauv tus txheej txheem ntawm kev siv, lub teeb lwj ntawm lub teeb pom kev zoo tshwm sim, thiab nws yuav tsis ci li thaum pib. Yog hais tias nws tsuas yog xam raws li thawj luminous flux, ces thaum lub brightness ntawm lub teeb txo, lub illuminance yuav tsis txaus.

Tsis tas li ntawd, lub teeb pom kev zoo ntawm lub teeb pom kev zoo yuav raug saib xyuas, thiab qhov cuam tshuam ntawm cov ntaub so ntswg yog pom tseeb dua. Qhov no kuj yooj yim to taub. Plua plav, thiab lwm yam yuav khaws cia rau ntawm lub teeb nyob rau lub sijhawm, uas tseem yuav cuam tshuam lub teeb pom kev zoo ntawm lub teeb, thiab ib txwm cuam tshuam rau lub teeb pom kev zoo. , yog li nws kuj yog ib qho parameter uas cuam tshuam rau kev saib xyuas. Cov nyhuv ntawm kev ntxuav lub teeb ib xyoos ib zaug lossis ob peb zaug sib txawv.

Nws kuj suav nrog qib ntawm kev ua qias tuaj ib puag ncig, uas kuj yooj yim to taub. Cov chaw uas muaj plua plav ntau yuav cuam tshuam rau lub teeb pom kev zoo ntawm cov teeb. Nws kuj suav nrog tus nqi thiab qib ntawm kev laus ntawm cov khoom siv hauv lub luminaire. Kuj tseem muaj ntau yam uas cuam tshuam rau kev saib xyuas ntawm lub teeb, xws li IP theem ntawm cov teeb thiab teeb. Nws yog ib qho yooj yim to taub tias yog tias qhov chaw nyob sab hauv tsev yog huv si thiab qhov zoo ntawm lub teeb lub teeb qhov chaw yog qhov zoo, qhov kev saib xyuas ntawm lub teeb tuaj yeem teeb tsa siab dua. Yog li ntawd, cov teeb pom kev zoo ntawm txoj kev dav dav zuj zus, thiab kev saib xyuas qhov tseem ceeb yog qis dua. Feem ntau, tus nqi ntawm qhov kev saib xyuas yog nyob ib puag ncig {{0}}.6, thaum qhov kev saib xyuas ntawm lub Hoobkas teeb pom kev zoo siab dua, feem ntau nyob ib puag ncig 0.7. Lub teeb pom kev hauv tsev feem ntau muaj qhov chaw nyob sab hauv tsev zoo dua, thiab qhov kev saib xyuas feem ntau yog nyob ib ncig ntawm 0.7-0.8.

Qhov kev saib xyuas feem ntau yog sawv cev los ntawm tsab ntawv Askiv loj K.

Thaum xam illuminance, ib qho parameter feem ntau yog siv, kev siv coefficient. Kev siv qhov tseem ceeb yog feem ntau cuam tshuam nrog qhov loj ntawm qhov chaw teeb pom kev zoo thiab cov khoom siv ntawm phab ntsa. Piv txwv li, yog tias qhov kev cuam tshuam ntawm lub qab nthab, phab ntsa, thiab hauv pem teb yog siab dua, tus nqi ntawm kev siv lub ntuj yuav ntau dua. Thaum xam kom raug lub teeb pom kev zoo, cov tuam txhab tsim khoom lag luam yuav muab lub rooj rau kev nug txog tus nqi ntawm kev siv coefficient. Kev siv coefficient feem ntau yog sawv cev los ntawm Askiv tus lej K.

Tus qauv dav dav rau xam qhov nruab nrab illuminance yog

Nruab nrab illuminance=luminous flux ntawm lub teeb * naj npawb ntawm cov teeb * txij nkawm yam * utilization factor / cheeb tsam

Hom kev xam qhov nruab nrab illuminance no feem ntau hu ua txoj kev lumen. Tsis tas li vim yog siv cov txiaj ntsig coefficient, nws tuaj yeem hu ua txoj kev coefficient.

Lwm txoj hauv kev yog tias cov chaw tsim khoom teeb yuav muab ib daim duab qhia txog tus naj npawb ntawm cov teeb raws li daim duab. Tus nqi siv ntawm qhov illuminance ntawm daim duab no feem ntau yog 100lx, uas yog tsim rau cov teeb pom kev zoo.

Peb kuj tau pom tias qhov no yog xam qhov nruab nrab illuminance, uas yog ib qho yooj yim xam. Xav txog cov yam ntxwv ntawm lub teeb pom kev zoo ntawm lub teeb ci thiab qhov hloov pauv ntawm qhov chaw ua haujlwm, qhov tseeb, lub teeb pom kev ntawm ib qho chaw, qhov sib txawv illuminance ntawm lub teeb qhov chaw thiab qhov chaw teeb pom kev zoo, qhov kev suav yog qhov nyuaj heev, tus nqi pes tsawg. feem ntau yog deviates los ntawm qhov nruab nrab illuminance nyob rau hauv ib tug tej yam ntau yam, uas yog hais tias, qhov nruab nrab illuminance tsuas yog qhia txog cov xwm txheej ntawm qhov chaw ua hauj lwm, thiab tsis sawv cev rau lub illuminance ntawm ib tug tshwj xeeb point.

Kev suav Brightness

Kev ci ntsa iab yog ib qho tseem ceeb cuam tshuam ncaj qha rau tib neeg txoj kev xav, tab sis vim li cas peb cov teeb pom kev dav dav piav qhia txog qhov pom kev zoo tshaj plaws yam tsis tau hais txog qhov ci? Tus nqi cuam tshuam nrog lub kaum sab xis ntawm tus neeg, qhov kev ncua deb, qhov kev xav ntawm qhov chaw ua haujlwm, thiab lwm yam. Muaj ntau qhov tsis paub tseeb. Kev suav ntawm illuminance yog qhov yooj yim kom muaj nuj nqis. Yog li feem ntau muab qhov illuminance.

Kev suav ntawm luminance yog qhov nyuaj dua. Txhawm rau xam cov luminance kom raug, kev siv computer-pab suav feem ntau yog siv tam sim no, thiab cov kev paub tsis zoo yog cov tswv yim los ntawm cov qauv software tsim nyog kom tau txais qhov tseeb luminance tus nqi.
