Yog tias koj puas tau yuav lub teeb thiab xav paub qhov txawv ntawm lumens thiab lux, tej zaum koj tseem xav txog nws niaj hnub no. Raws li cov teeb pom kev zoo tau nrov dua vim tias muaj kev siv thev naus laus zis ntau ntxiv, thiab raws li cov ntxaij vab tshaus projector coj peb cov chaw ua yeeb yam hauv tsev, ob peb tus neeg nkag siab qhov tseem ceeb ntawm cov ntsuas no. Txhawm rau pab koj nkag siab lawv txoj kev sib raug zoo, peb tau txhais lawv ib sab.
Lux yog dab tsi?
Kev ntsuas teeb pom kev zoo yog hu ua lux unit (cim: lx). Ib qhov chaw yuav raug teeb pom kev zoo, xws li lub hnub ci lossis teeb pom kev zoo.
Ntau lub teeb tawm tsam qhov chaw ze dua nws mus rau lub teeb ci. Tus lej lux yuav nce raws li qhov tshwm sim.
Vim nws cov qib siab ntawm qhov sib txawv, lux ratings feem ntau suav nrog cov kev cai. "500lx ntawm 2m nrug" yog ib qho piv txwv ntawm qhov no.
Cov neeg siv khoom tuaj yeem siv nws los ntsuas seb lub teeb pom kev zoo li cas ntawm qhov muag liab qab. Qhov no yog vim li cas lumens tsuas yog cuam tshuam rau qhov tseeb ntawm lub teeb uas tsim tawm.
Lumens yog dab tsi?
Lub lumen yog ib chav ntsuas rau lub teeb siv, thiab lo lus yog muab los ntawm Latin lumen, uas txhais tau tias "lub teeb." Kev sib piv cov teeb pom kev zoo thoob plaws qhov chaw sib txawv yog ib qho kev coj ua hauv kev tsim teeb pom kev zoo.
Qhov ci ntsa iab ntawm qhov muag teev yog nquag teev siv cov kev ntsuas lumen. Tsis tas li ntawd, nws ntsuas cov cuab yeej teeb pom kev zoo thiab cov teeb pom kev zoo.
Txij li thaum lub teeb lub zog radiates los ntawm ib qhov chaw nyob rau hauv tag nrho cov kev taw qhia, ib tug lumen yog ib tug tiag tiag lub cev chav tsev ntawm kev ntsuas uas yog haum rau muab piv rau ntau yam teeb thiab teeb pom kev zoo systems. Nws kuj yog qhov hloov pauv tsawg dua li lux.
Lumens muab qhov ntsuas tseeb dua ntawm qhov koj tau txais ntau npaum li cas. Kev nyeem lumen tso cai rau kev sib piv zoo dua ntawm hom teeb pom kev zoo. Lux tsis muaj tus qauv zoo li no, vim tias nws tso siab rau kev nkag siab txog kev xav. Yog li nws yuav hloov tau nyob ntawm tej yam xws li lub wavelength ntawm lub teeb.
Muaj pes tsawg Lumens nyob hauv ib lub Lux?
Yog xav paub ntxiv qhov tseem ceeb, koj tuaj yeem suav qhov sib piv siv lub tshuab xam zauv lux vs. lumen.
Raws li ib qho piv txwv, xav tias koj muaj lub teeb pom kev zoo nrog lub lumen tshwj xeeb. Tus lej ntawm lux yuav yog dab tsi? Ib lub lux yog sib npaug rau ib lub teeb rau ib square meter.
Rau kev sib piv, kwv yees li 10,000 lx yog lub teeb ci ntawm qhov tsis ncaj qha tshav ntuj. Nyob rau hnub huab cua, tus nqi yuav qis li 1000 lx, thaum nyob rau hauv tshav ntuj ncaj qha, nws yuav ncav cuag 100,000 lx.
Thaum twg siv Lux vs Lumens?
Qhov kev piav qhia yooj yim tshaj plaws yog tias koj ntsuas lub teeb los ntawm qhov chaw, koj ntsuas nws hauv lumens, tab sis yog tias koj ntsuas ntau npaum li cas ntawm lub teeb mus txog qhov chaw, koj ntsuas nws hauv lux. Yog li ntawd, nws muaj kev ruaj ntseg hais tias ib tug tsis tuaj yeem nyob tsis muaj lwm tus, tab sis nyob ntawm koj cov ntaub ntawv siv, ib qho tseem ceeb dua li lwm tus. Txhawm rau qhia tias ob qho tib si tshwm sim li cas ntawm ib sab hauv tib qhov chaw, peb tau suav nrog cov piv txwv zoo tshaj plaws ntawm lub tsev ua yeeb yam hauv qab no.
Lux vs Lumens Projector Piv txwv
Xav tias koj tab tom yuav ib lub vijtsam dawb ua ke nrog lub projector. Tom ntej no, koj yuav tsum paub seb muaj pes tsawg lumens lub projector tsim. Cov duab yuav ci dua qhov ntau lumens muaj.
Paub tias tuaj yeem pab tau, nyob ntawm koj cov ntaub ntawv siv. Vim yog qhov siv ntawm ntuj teeb pom kev zoo, sab nraum zoov projectors yuav tsum tsim ntau lumens ntau dua li sab hauv. Qhov ntawd muaj ntau yam txaus los ua kom cov kev teeb tsa hloov tau yooj yim dua.
Piv txwv li, qhov ntsuas lux "1000lx ntawm 2m" pab txiav txim siab qhov kev tso kawm zoo tshaj plaws. Piv txwv tias koj muaj qhov chaw nyob hauv koj chav nyob rau 120 "qhov projection, nws muaj peev xwm hais tias koj chav tsev ci ntsa iab heev thiab lub projector tsis tsim cov lumens txaus kom mus txog rau sab nraud ntawm chav tsev.
Yuav Ua Li Cas Ntsuas Lux vs Lumens
Lumens piv rau lux yog ib qho yooj yim los ntsuas. Txawm hais tias muaj ob peb lub lux thiab lumen meters muaj, kev yuav lub teeb pom kev zoo yog txoj hauv kev zoo tshaj plaws.
Thaum qee lub teeb ntsuas ntsuas tau ntsuas ob qho tib si lux thiab lumens, ob peb tau qhia meej los ntsuas lumens. Thaum lub sijhawm ntawd, koj yuav tsum paub txog qhov koj ntsuas tau txhawm rau txhawm rau tshuaj xyuas qhov cuam tshuam. Txhawm rau kom tau txais qhov ntsuas lux, koj tuaj yeem hloov pauv siv lub lumens rau daim ntawv nrug.
Yog tias koj muaj teeb meem suav nrog lumens, ntsuas qhov tseeb ntawm lub teeb hauv chav tsev yog txoj hauv kev zoo kom tau txais cov lej tseeb. Rau kev sib piv, koj yuav tsum muaj lub projector ntawm tes yog tias koj tab tom txiav txim siab yuav ib qho, yog li koj tuaj yeem txiav txim siab sai npaum li cas rau koj.
