Qhov nruab nrab qhov pom kev

1. a = ntev ntawm chav nyob hauv meters;
2. b = dav ntawm cheeb tsam hauv meters;
3. 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 L_LF) 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:

1. Tus naj npawb ntawm kab nrog teeb pom kev zoo = 4.
2. Tus naj npawb ntawm teeb pom kev zoo hauv txhua kab = 5.
3. Axial nrug nruab nrab ntawm fixtures = 4.0 meter.
4. Kev ncua deb nruab nrab ntawm cov khoom siv = 2.5 meter.
5. Yuav tsum muaj tag nrho cov teeb tsa = 21.
