Kev suav ntawm Illumination Intensity rau Clean Room Engineering
Txoj kev no yog siv los xam qhov nruab nrab illuminance
(Luminous flux of light source) (CU) (MF) Illumination area
Haum rau sab hauv tsev thiab kev ua kis las teeb pom kev zoo
Kev siv coefficient: feem ntau {{0}}.4 rau kev siv sab hauv tsev thiab 0.3 rau kev siv kis las
1. Illumination faib cov teeb
2. Luminaire efficiency
3. Tus txheeb ze txoj hauj lwm ntawm lub teeb nyob rau hauv lub illuminated cheeb tsam
4. Reflected lub teeb nyob rau hauv ib puag ncig
Kev saib xyuas coefficient MF{{0}}}(LLD) X (LDD) feem ntau yog siv li 0.7-0.8
Piv txwv 1:
Sab hauv teeb pom kev zoo, 4 × 5 meter chav, siv 3 × 9 teeb ntawm 36W daim phiaj teeb
Qhov nruab nrab illuminance=tag nrho cov luminous flux ntawm lub teeb qhov chaw × CU × MF/Area
{{0}}(2500 × 3 × 9) × xoom taw tes plaub × 0.8 ÷ 4 ÷ 5
=1080 Lux
Xaus: Qhov nruab nrab illumination yog siab dua 1000Lux
Piv txwv 2:
Gymnasium teeb pom kev zoo, 20 × A 40 meter teb,
60 teeb ntawm POWRSPOT 1000W hlau halide teeb siv
Qhov nruab nrab illuminance=tag nrho cov luminous flux ntawm lub teeb qhov chaw × CU × MF/Area
{{0}}(105000 × 60) × zero point peb × 0.8 ÷ 20 ÷ 40
=1890 Lux
Xaus: Qhov nruab nrab kab rov tav illumination yog siab dua 1500Lux
Vertical illumination saum 1000Lux (nyob ntawm qhov chaw teeb tsa)
