Qhov nruab nrab qhov pom kev
- a = ntev ntawm chav nyob hauv meters;
- b = dav ntawm cheeb tsam hauv meters;
- h = nrug nyob rau hauv meters ntawm lub teeb fixtures thiab lub dav hlau uas koj yuav tsum ntsuas illuminance (piv txwv li qhov siab ntawm teeb pom kev zoo 2.80 m, worktop ntawm qhov siab 0.8 m, h = 2.80 txog 0.8 = 2).
Ib yam li ntawd, nws yog nug, koj ua li cas xam illuminance?
Cov mis E = F x UF x MF / A rau teeb pom kev zoo E (qee zaum qhia tau tias yog kuv), tus nqi nruab nrab lumens los ntawm lub teeb pom kev F (qee zaum L.l), coefficient ntawm kev siv UF (lossis C.ua) thiab lub teeb pom kev zoo txij nkawm MF (lossis LLF) thiab thaj tsam ib lub teeb A.
Tom qab ntawd, lo lus nug yog, Lux qib xam yog dab tsi? Cov Muab xam los ntawm LUX qib hauv ib chav The LUX qib hauv ib chav yog xam los ntawm cov qauv hauv qab no. E( LUX ) = F(lm) x UF x MF / A. Where. E yog lub LUX qib ua tiav. F yog qhov nruab nrab lumens tus nqi tsim lub teeb ci.
Tom qab ntawd, lo lus nug yog, qhov nruab nrab qhov pom kev zoo yog dab tsi?
' Qhov nruab nrab qhov pom kev yog 'The teeb pom kev zoo nruab nrab ntawm ib cheeb tsam tshwj xeeb. Hauv kev xyaum, qhov no tuaj yeem muab tau los ntawm ib qho nruab nrab ntawm qhov pom kev ntawm tus lej sawv cev fo cov ntsiab lus ntawm qhov chaw, lossis los ntawm tag nrho cov teeb pom kev zoo poob rau ntawm qhov chaw faib los ntawm tag nrho cheeb tsam ntawm qhov chaw '
Muaj pes tsawg luminaires kuv xav tau lub tshuab xam zauv?
Txog tam sim no, peb tau suav cov hauv qab no:
- Tus naj npawb ntawm kab nrog teeb pom kev zoo = 4.
- Tus naj npawb ntawm teeb pom kev zoo hauv txhua kab = 5.
- Axial nrug nruab nrab ntawm fixtures = 4.0 meter.
- Kev ncua deb nruab nrab ntawm cov khoom siv = 2.5 meter.
- Yuav tsum muaj tag nrho cov teeb tsa = 21.
Pom zoo:
Koj ua li cas xam cov teeb pom kev hauv chav?
Teeb pom kev zoo - Cov ntsiab lus xam cov lumens koj xav tau. Muab cov cheeb tsam hauv square metres los ntawm lux, lossis thaj tsam hauv square feet los ntawm footcandles. ua hauj lwm seb muaj pes tsawg qhov muag teev koj xav tau. Faib tus naj npawb ntawm lumens los ntawm tus naj npawb ntawm lumens xa los ntawm txhua lub teeb
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
Koj puas tuaj yeem nruab nruab nrab qhov ntsuas phoo?
Koj tseem tuaj yeem kaw lub qhov rooj tom qab kom yooj yim kom cov menyuam yaus nyob hauv tsheb. Txhawm rau hloov koj lub tsheb mus rau lub qhov rooj xauv nruab nrab koj xav tau pob khoom, uas koj tuaj yeem npaj tau yuav los ntawm lub khw khoom siv tsheb. Nws kuj tseem tuaj yeem siv rau yuav luag txhua tus qauv ntawm lub tsheb, tab sis koj yuav tsum txheeb xyuas nrog koj tus neeg muag khoom ua ntej yog tias koj lub tsheb tsis haum
Koj xam xam qhov chaw txav chaw nyob li cas?
Txhawm rau txiav txim siab qhov hloov chaw ntawm qhov chaw nres nkoj, peb tsuas yog muab thaj tsam hla ntu los ntawm qhov ntev ntawm qhov chaw nres nkoj (uas peb tau txiav txim siab ua 12 "hauv qhov piv txwv no.) Displaced Volume = 9.61625 X 12 = 115.395 cu.in
Qhov kev tuav pov hwm cov tswv tsev ntau npaum li cas ntawm qhov nruab nrab?
Qhov nruab nrab txhua xyoo kev tuav pov hwm cov tswv tsev yog nyob ib ncig ntawm $ 1,200, tab sis cov nqi sib txawv ntawm lub xeev mus rau lub xeev thiab ib lub tsev rau ib lub tsev
