xam tus nqi ntawm lumens koj xav tau. Muab thaj tsam hauv thaj tsam ib square metres los ntawm qhov zoo nkauj, lossis thaj tsam hauv square feet los ntawm tus hneev taw. ua haujlwm seb koj xav tau pes tsawg qhov muag teev. Faib tus naj npawb ntawm lumens los ntawm tus naj npawb ntawm lumens xa los ntawm txhua lub teeb
Ua li no, koj xam lub teeb pom kev zoo hauv chav li cas?
Rau Ntuj Teeb Yog li, yog tias a chav yog 10 feet dav x 12 feet ntev, ces tus chav thaj tsam yuav yog 120 square feet thiab qhov tsawg kawg nkaus ntawm qhov rais hauv qhov ntawd chav yuav tsum yog 12 square feet. Ib tug peb ko taw los ntawm plaub ko taw qhov rais yuav muab 12 square feet ntawm lub teeb ntuj mus rau chav - dua, qhov xav tau yam tsawg kawg nkaus.
Ntxiv mus, kuv yuav suav lumens rau chav li cas? Lumens yog a ntsuas ntawm brightness, los yog tus nqi ntawm lub teeb emitted ib ob los ntawm ib lub teeb qhov chaw. Yuav kwv yees tus naj npawb ntawm lub lumens koj qhov chaw yuav xav tau , tsuas yog muab cov duab square ntawm koj xwb chav los ntawm tus naj npawb ntawm ko taw tswm ciab yuav tsum tau rau qhov chaw.
Ntxiv mus, kuv yuav xam LED teeb rau ib chav li cas?
- Ntawm no yog yuav txiav txim siab pes tsawg LED Lumens koj yuav xav tau kom teeb pom kev zoo rau koj qhov chaw.
- Txoj Kev tawg- Lub teeb Muaj pes tsawg lub teeb txaus?
- Txiav txim siab Room Square Footage. Muab qhov ntev lub sij hawm qhov dav ntawm chav tsev kom tau chav Square Footage.
- Txiav txim taws tswm ciab los ntawm chav tsev lossis chav tsev hom phiaj.
- Cov ntsiab lus ceev.
Koj yuav ua li cas thiaj pom lub ntuj kaj nyob hauv chav tsaus?
Tsom iav tsom iav qhov rai los yog lub qhov rooj iav kom ua tau zoo tshaj lub teeb ntuj hauv koj chav . Tswv yim: Yuav cov rooj tog nrog iav panels los yog mirrored accents.

Koj xam xam lux thiab lumens li cas?
1 lx = 1 lm/mm2. 1 Lumen ib Square Meter: Lumen ib square meter sib npaug rau Lux (SI unit). Kev ntsuas tus naj npawb ntawm Lumens poob ntawm thaj tsam ntawm ib square meter, lub ntsiab lus ntawm Lux
Dab tsi yog qib pom kev teeb pom kev zoo rau kev ua haujlwm hauv chaw ua haujlwm?
Lub teeb pom kev sab nraum zoov yog kwv yees li 10000 lux nyob rau hnub pom tseeb. Hauv ib lub tsev hauv cheeb tsam ze rau ntawm lub qhov rais, lub teeb ci tuaj yeem txo qis mus rau kwv yees li 1000 lux. Hauv nruab nrab cheeb tsam nws yuav qis li 25 - 50 lux. Sab hauv tsev teeb theem. Kev Ua Haujlwm Teeb pom kev zoo (lx, lumen / m2) Kev ua haujlwm yooj yim 250 Chav Chav 300
Koj xam xam qhov nruab nrab qhov pom kev li cas?
Qhov nruab nrab qhov ci ntsa iab a = ntev ntawm chav nyob hauv meters; b = dav ntawm cheeb tsam hauv meters; h = nrug deb ntawm qhov nruab nrab ntawm cov teeb pom kev zoo thiab lub dav hlau uas koj yuav tsum ntsuas lub teeb pom kev zoo (piv txwv li qhov siab ntawm cov teeb pom kev zoo 2.80 m, qhov chaw ua haujlwm ntawm qhov siab 0.8 m, h = 2.80 txog 0.8 = 2)
Yuav ua li cas lux qib xam rau txoj kev teeb pom kev zoo?
Qhov Nruab Nrab Lux Qib ntawm Txoj Kev Teeb yog ntsuas los ntawm 9 point method. Ua ob qhov sib npaug sib npaug nruab nrab ntawm ob txoj kev teeb pom kev. Peb muaj 3 ntsiab lus P1, P2 thiab P3 nyob rau hauv lub teeb ncej ces P4 & P7 yog cov ntsiab lus opposite ncej 1 los yog Point P3 tib yam muaj feem xyuam rau P6 thiab P9 rau ncej 2
