Xam Xaj Kev Sib Raug ZooNruab nrab ntawm Floodlight Installation Qhov siab thiab Beam Angle
Kev sib raug zoo ntawm lub teeb ci ntsa iab qhov siab thiab nws lub kaum sab xis (25 degree, 60 degree, 120 degree, thiab lwm yam) txiav txim siab qhov loj thiab siv ntawm thaj chaw illuminated. Qhov kev sib txuam tseem ceeb no ua kom muaj kev pom zoo rau cov ntawv thov tshwj xeeb, los ntawm cov kis las mus rau lub tsev facades. Kev suav yog nyob ntawm theem pib trigonometry, siv lub kaum sab xis los txiav txim siab qhov sib kis ntawm lub teeb ntawm qhov siab.
Cov kev sib raug zoo tseem ceeb yog muab los ntawm tangent muaj nuj nqi, uas hais txog lub installation qhov siab (H) mus rau lub vojvoog (R) ntawm lub illuminated cheeb tsam:
R=H × tan(θ/2).
Qhov twg:
R=Radius ntawm lub voj voog illuminated (m).
H=Kev teeb tsa qhov siab tshaj ntawm lub hom phiaj nto (m).
θ=Beam kaum sab xis (degree), feem ntau teev raws li lub kaum sab xis ntawm ob lub ntsiab lus uas lub teeb siv zog poob mus rau 50% ntawm lub ncov (ib nrab- lub zog lub kaum ntse ntse).
Cov mis no ua haujlwm rau lub kaum sab xis ntawm lub kaum sab xis (feem ntau hauv cov teeb pom kev zoo). Rau cov kab teeb asymmetric, cais cov suav suav siv rau cov kab rov tav thiab ntsug.
1. 25℃Narrow Beam
Lub teeb dej nyab nrog lub kaum sab xis ntawm 25℃beam mounted ntawm 10m qhov siab:
luas luas=luas=1/25/25 x 12.5 m²
Tag nrho txoj kab uas hla=4.44m. Lub nqaj nqaim no tsom lub teeb hauv thaj chaw me me, zoo tagnrho rau kev nthuav dav cov ntsiab lus ntawm cov vaj tsev lossis cov chij.
2. 60℃Nruab nrab Beam
Ntawm 10m qhov siab nrog 60℃nqaj kaum sab xis:
luas luas=luas=1/2 x 10 x 2=30 m²
Tag nrho txoj kab uas hla=11.54m. Qhov sib npaug sib npaug no haum rau thaj chaw teeb pom kev zoo, xws li chaw nres tsheb lossis chaw thau khoom
3. 120℃Wide Beam
Rau 120℃beam kaum ntawm 10m qhov siab:
luas luas=luas=1/2 x 120=120 cm²
Tag nrho txoj kab uas hla=34.64m. Qhov kev sib kis dav no yog qhov loj rau - thaj chaw teeb pom kev zoo xws li chaw ua si lossis chaw ua haujlwm.
Cov Lus Qhia Txog Kev Thov
Cov kab nqaim nqaim (25 degree): Yuav tsum muaj qhov siab dua mounting kom ua tiav qhov dav dav. Piv txwv li, kom npog thaj tsam 10m txoj kab uas hla, 25℃beam xav tau:
H=R / tan (12.5 degree)=5m / 0.2217 ≈ 22.5m
Qhov no ua rau lawv tsis tsim nyog rau kev teeb tsa qis tab sis zoo heev rau ntev - tsom teeb pom kev deb.
Nruab nrab kab teeb (60 degree): Muaj ntau yam. Mounted ntawm 8m, 60℃beam npog ib txoj kab uas hla 9.23m (R=8 × tan(30 degree) ≈ 4.61m), zoo tagnrho rau khw muag khoom chaw nres tsheb lossis lub tsev perimeters.
Cov kab dav dav (120 degree): Excel ntawm qhov siab qis. Ntawm 5m, lawv npog 17.32m txoj kab uas hla, ua rau lawv muaj txiaj ntsig zoo rau kev teeb pom kev loj, qis - qab nthab qhov chaw xws li warehouses.
Cov ntsiab lus tseem ceeb
Light Intensity: Illuminance (lux) txo qis nrog cov square ntawm kev ncua deb. Lub 120℃beam ntawm 10m ua rau qis peak lux tshaj li 25℃beam ntawm tib qhov siab, txawm tias nws npog ntau thaj chaw.
Lub kaum sab xis: Cov neeg tsim khoom 'beam lub kaum sab xis yuav txawv ntawm ± 5 degree, yog li suav nrog 10% kev nyab xeeb ntawm kev suav.
Mounting Tilt: Yog tias lub teeb pom kev nyab xeeb yog qaij (tsis yog perpendicular rau saum npoo), kho H mus rau txoj kab ntsug ntawm qhov chaw sib tw mus rau thaj chaw lub hom phiaj, tsis yog qhov siab ntawm lub cev.
Los ntawm kev siv cov qauv no, cov neeg tsim khoom tuaj yeem ua tau raws cov kab teeb ci rau qhov siab ntawm kev teeb tsa, ua kom muaj kev tiv thaiv zoo ib yam thiab tsis txhob nkim lub teeb lossis qhov chaw tsaus.
