Hluav taws kub ceev teeb pom kev zoo illumination yuav tsum
Hluav taws kub ceev teeb pom kev zoo qhov yuav tsum tau muaj_Kev ntsuas teeb pom kev kub ceev
Hluav taws kub ceev teeb pom kev zoo luminaires illuminance yuav tsum:
① Kev khiav tawm hauv av yuav tsum tsis pub tsawg dua 0.5 lx yam tsawg kawg nkaus ntawm lub teeb pom kev;
② qhov tsawg kawg nkaus ntawm qhov teeb pom kev hauv av hauv qhov chaw muaj neeg coob yuav tsum tsis txhob tsawg dua 1.0 lx;
③ Qhov tsawg kawg nkaus ntawm lub teeb pom kev hauv pem teb hauv lub stairwell yuav tsum tsis pub tsawg dua 5.0 lx;
④ Lub teeb pom kev khiav tawm hluav taws tau teeb tsa hauv qhov chaw khiav tawm, stairwells, cov pa luam yeeb hauv pem hauv ntej, cov chaw pej xeem thiab lwm qhov chaw ntawm kev khiav tawm hluav taws ua haujlwm, qhov tsawg kawg nkaus illumination tus nqi yuav tsum tsis pub tsawg dua 5.0 lx
⑤ Cov teeb pom kev kub ceev hauv chav tswj hluav taws, chav hluav taws kub twj tso kua mis, chav tsim hluav taws xob tus kheej, chav faib hluav taws xob, chav pa taws thiab pa taws thiab lwm chav uas tseem yuav tsum tau ua haujlwm ib txwm nyob hauv qhov hluav taws kub tseem yuav ua kom lub teeb pom kev zoo ntawm lub teeb pom kev zoo.
Qhov nruab nrab illuminance xam mis:
Txoj kev siv cov khoom siv: Eav=φ (tus kheej luminous flux) * N (tus lej) * CU (qhov chaw siv qhov khoom) * MK (qhov tseem ceeb tu) / S (chaw)
Qhov kev siv qhov chaw feem ntau yog siv li {{0}}.3~0.4, thiab qhov kev saib xyuas feem ntau yog coj li {0.7~0.8;
Chav tsev muaj peev xwm txoj kev: W (chaw illuminated cheeb tsam xav tau lub zog)=P (tag nrho cov teeb lub zog) / S (illuminated cheeb tsam)
Conversion: N (ntau lub teeb) {{0}} E (yuav tsum tau illuminance) * A (chav cheeb tsam) * φ0 (unit cheeb tsam ib LX luminous flux) * C1 (correction coefficient) * C2 ( kho coefficient) / φ (tus kheej lub teeb luminous flux)
Point los ntawm point xam txoj kev: ntau complex, tsis teev.
Kev kawm dav dav illuminance yog 100Lux, tab sis lub teeb pom kev zoo xav tau rau kev nyeem ntawv yog 600Lux, yog li nws yog qhov zoo tshaj plaws los siv lub rooj teeb ua teeb pom kev hauv zos.
Sab hauv tsuas pom cov qauv ntawm tib neeg lub ntsej muag, illuminance rau 20LX, ua si chess thiab phaib illuminance rau 150LX, nyeem ib tug tshiab txog 250LX, uas yog, 25 watts ntawm incandescent teeb deb ntawm phau ntawv 30-50 centimeters, sau txog 500LX , uas yog, 40 watts ntawm incandescent teeb nyob deb ntawm phau ntawv 30-50 centimeters, saib TV txog 30LX, nrog ib tug 3-watt teeb sab nraum cov kab pom ntawm kab.
Tswj lub teeb pom kev zoo, txhim kho kev ua haujlwm ntawm kev ua haujlwm thiab kev kawm muaj txiaj ntsig zoo; nyob rau hauv lub zog heev los yog tsaus nti irradiation ua hauj lwm thiab kawm, lub qhov muag yog teeb meem.
Qhov loj ntawm illumination siv los ntawm tib lub teeb
1). Muaj feem xyuam rau hom teeb, lub teeb efficiency thiab lub teeb faib nkhaus.
2). Nrog lub teeb dai qhov siab. Qhov siab dua qhov kev ncua, qhov ntau pom lub teeb flux, qhov kev siv ntau dua.
3). Muaj feem xyuam rau thaj tsam thiab cov duab ntawm chav tsev. Qhov loj dua qhov chaw ntawm chav tsev, thiab qhov ze dua rau ib lub square, qhov kev siv ntau dua yuav yog vim qhov nce ntawm lub teeb ncaj qha flux.
4). Nws muaj feem xyuam rau cov xim thiab kev huv ntawm cov phab ntsa, qab nthab thiab cov plag tsev. Qhov sib zog ntawm cov xim thiab qhov huv ntawm qhov chaw, qhov ntau lub teeb flux yog reflected thiab yog li qhov kev siv ntau dua.
