Thaum muaj coob tus neeg nug txog tus nqi, lawv thawj lo lus nug feem ntau yog, "Dab tsi yog qhov wattage ntawm koj lub teeb kis las kis las?" Tsis tshua muaj lawv nug txog lub kaum sab xis ua ntej. Txawm li cas los xij, hauv cov haujlwm tiag tiag, xaiv lub kaum sab xis tsis ncaj ncees ua rau mob taub hau ntau dua li xaiv cov wattage tsis txaus: koj tuaj yeem ua tiav qhov ci ntsa iab, tab sis qhov chaw xaus nrog lub teeb pom kev tsis sib xws (ci thiab tsaus nti), cov neeg ua si tau dazzled los ntawm glare, thiab cov neeg nyob ze yws txog lub teeb muaj kuab paug. Tsis muaj ib qho "zoo tshaj beam kaum" rauteeb pom kev hauv chaw ntau pob; muaj tsuas yog lub kaum sab xis uas yog "tsim nyog rau qhov tshwj xeeb teb, mounting qhov siab, thiab luminaire txoj hauj lwm." Hauv qab no, peb piav qhia txog yam tseem ceeb uas yuav tsum tau xav txog thaum lub sijhawm xaiv.
Dab tsi yog beam angle?
Beam lub kaum sab xis yog hais txog lub kaum sab xis tsim los ntawm lub teeb tawm los ntawm lub teeb pom kev zoo uas qhov luminous siv tau poob mus rau 50% ntawm nws cov nqi siab tshaj. Lub kaum sab xis me me txhais tau hais tias lub teeb muaj ntau dua thiab mus ntxiv; lub kaum sab xis loj dua txhais tau tias lub teeb tawg ntau dua, npog thaj tsam dav dua tab sis ua rau qis qis hauv nruab nrab.
Kev lag luam kuj feem ntau siv NEMA kev faib tawm los piav txog cov kab teeb:
NEMA 1–2: Approx. 10℃-29℃(ntxiv- nqaim rau nqaim)
NEMA 3–4: Approx . 29℃-70℃(nruab nrab beam)
NEMA 5-7: Tshaj 70℃(nqaj nqaj)
Thaum tshuaj xyuas cov luminaire specifications, nco ntsoov qhov txawv ntawm "beam angle" (50% siv) thiab "field angle" (10% siv). Lub kaum sab xis feem ntau yog dav dua li lub kaum sab xis ntawm lub nqaj, qhov tseem ceeb uas cuam tshuam ncaj qha rau kev tswj lub teeb ci.
Kev sib raug zoo ntawm beam angle, mounting qhov siab, thiab projection nrug
Qhov pib taw tes rau xaiv lub kaum sab xis yog qhov projection nrug. Nov yog ib txoj kev kwv yees yooj yim:
Lub teeb chaw txoj kab uas hla ≈ 2 × Projection nrug × tan (Beam kaum / 2)
Piv txwv li: Yog hais tias lub fixture yog 30 meters los ntawm lub hom phiaj taw tes nrog ib tug 30℃beam kaum sab xis, qhov chaw txoj kab uas hla yog kwv yees li 16 meters; Nyob rau tib qhov deb, lub kaum sab xis ntawm 60℃ua rau qhov chaw txoj kab uas hla ntawm kwv yees li 35 meters.
Cov qauv no tsuas yog muab kev kwv yees ntxhib xwb; Nyob rau hauv kev muaj tiag, ib tug yuav tsum tau account rau lub elliptical zoo ntawm lub teeb qhov chaw tshwm sim los ntawm lub fixture lub qaij lub kaum sab xis, nrog rau cov overlapping ntawm lub teeb me ntsis. Txawm li cas los xij, nws ua haujlwm raws li txoj cai ceev ntawm tus ntiv tes xoo: xaiv lub kaum sab xis nqaim rau qhov ntev thiab qhov dav dav rau qhov luv luv.
Reference ranges for beam angles by sport
Cov duab hauv qab no yog cov lus qhia txog kev ua kis las; Qhov kawg specifications yuav tsum yog raws li illuminance simulations (piv txwv li, DIALux los yog AGi32):
Ncaws pob thiab rugby teb (ncej qhov siab 20-35m):Feem ntau 15℃-40 degree; kev sib xyaw ntawm beam kaum feem ntau yog siv.
Baseball thiab softball teb:25℃-45℃rau infield; cov kaum sab xis rau qhov chaw tawm thiab siab - pob zones.
Tennis courts (nce siab 8-12m):Feem ntau 40℃-70 degree, lossis asymmetrical teeb faib.
Sab nraum zoov basketball tsev hais plaub (ncej qhov siab 8-12m):Feem ntau 50℃-80 degree.
Cov chaw ua si sab hauv tsev thiab cov tsev hais plaub ntaus pob (qhov siab 7-12m):Feem ntau 60℃-110 degree; qhov tseem ceeb yog uniformity thiab qis glare.
Track thiab teb arenas:Lub kaum ntse ntse rau qhov chaw khiav; nqaim- lub kaum sab xis yuav siv tau rau kev dhia thiab ntuav ntu.
Yuav ua li cas ncej layout cuam tshuam beam kaum xaiv
Rau txhua qhov chaw, qhov chaw ntawm lub teeb ncej dictates lub configuration ntawm beam angles.
Plaub -pob layout:Qhov kev ncua deb mus rau qhov chaw nruab nrab yog qhov tseem ceeb, yuav tsum tau nqaim nqaim rau qhov ntev - qhov projection, ntxiv los ntawm cov kab nruab nrab rau thaj tsam ze ntawm cov ces kaum.
Sab -mounted layout:Qhov kev ncua deb ntawm lub teb yog luv luv thiab sib npaug; nruab nrab beam kaum sab xis predominate, ntxiv los ntawm ob peb nqaim- lub kaum sab xis rau qhov chaw nruab nrab.
Surround layout (loj stadiums): Ib tug ncej feem ntau nqa ib qho sib xyaw ntawm cov kab teeb kom npog ze, nruab nrab, thiab thaj tsam deb.
Cov kev paub dhau los qhia tias tsis txhob siv lub kaum sab xis ntawm lub kaum sab xis ntawm tag nrho tus ncej; sib xyaw cov ces kaum sib txawv ua rau smoother, ntau yam illuminance nkhaus.
Pros and Cons of Narrow vs. Wide Beam Angles
Lub kaum sab xis nqaim (kwv yees . 10℃-30 degree)
Pros: Ntev mus deb, siab nruab nrab luminous siv (tsim rau ntev - ntau qhov projection los ntawm siab masts); Lub teeb pom kev zoo nrog lub teeb me me.
Cons: me me lub teeb qhov chaw, yuav tsum tau ntxiv fixtures rau tag nrho cov kev pab them nqi; me ntsis deviations nyob rau hauv aiming lub kaum sab xis ua rau pom pom hotspots thiab tsaus ntuj.
Lub kaum sab xis dav (kwv yees . 60℃lossis siab dua)
Pros: cheeb tsam loj, lub teeb hloov pauv, thiab yooj yim dua kom ua tiav qhov sib xws; haum rau qis mounting qhov siab.
Cons: txwv pov tseg (khoom luminous flux yog siv rau siab masts); nquag ua rau lub teeb nchuav, cuam tshuam rau ib puag ncig ib puag ncig.
Nruab nrab Beam Lub kaum sab xis (kwv yees . 30}℃-60℃): Strikes qhov sib npaug ntawm ob thiab yog qhov kev xaiv tseem ceeb rau feem ntau me me - mus rau - nruab nrab - qhov chaw loj.
Kev sib raug zoo ntawm Beam Angle, Glare, thiab Spill Light
Kev ua kis las teeb pom kev zoo tsis yog tsuas yog hais txog qib illuminance; qhov pom kev nplij siab ntawm cov players thiab cov neeg saib yog qhov tseem ceeb sib npaug.
Yog tias lub kaum sab xis dav dav thiab qhov kev sib tw yog tsom rau ntawm lub kaum sab xis, lub teeb tuaj yeem nkag mus rau cov neeg ua si qhov kev pom tau yooj yim, uas ua rau muaj kev ntsuas siab glare (GR).
Yog tias lub kaum sab xis nqaim dhau thiab lub hom phiaj lub kaum ntse ntse dhau, qhov kev xav tawm ntawm lub pob saum npoo tuaj yeem tshwm sim, cuam tshuam kev taug qab ntawm siab - cov pob trajectory.
Thaum tswj tau tawm - qhov chaw teeb pom kev zoo yog qhov tsim nyog, nqaim - nqaj teeb txuas nrog baffles lossis louvers raug pom zoo.
Yog tias qhov chaw nyob ib sab ntawm thaj chaw nyob lossis txoj kev, qhov kev xaiv ntawm lub kaum sab xis yuav tsum tau txiav txim siab nrog rau qhov yuav tsum tau ua kom pom lub teeb pom kev zoo, tsis yog tsom tshwj xeeb rau ntawm - thaj chaw teeb pom kev zoo.
Common Pitfalls hauv Beam Angle Xaiv
Tsom ntsoov rau ntawm lub kaum sab xis ntawm daim duab thaum tsis quav ntsej txog lub teeb faib nkhaus: Ob lub teeb uas sau tias "30 degree" tuaj yeem tsim cov qauv teeb pom kev sib txawv vim qhov txawv ntawm qhov muag pom; ib txwm sab laj cov ntaub ntawv IES.
Siv ib lub kaum sab xis thoob plaws:Standardizing txhua lub teeb rau ib lub kaum sab xis rau kev yuav khoom yooj yim feem ntau ua rau nws nyuaj kom ua tau raws li cov qauv kev sib xws thoob plaws hauv nruab nrab thiab cov npoo ntawm qhov chaw.
Overlooking fixture qaij lub kaum sab xis:Beam angles thiab installation qaij lub kaum sab xis yog tsim los ua haujlwm hauv tandem; hloov lub kaum sab xis yam tsis rov- simulating lub teeb pom kev zoo feem ntau tau txais txiaj ntsig uas poob qis ntawm qhov kev cia siab.
Ua tsis tiav rau kev hloov kho yav tom ntej:Qee qhov haujlwm xav tau kev hloov pauv ntawm kev cob qhia thiab kev sib tw hom; Nws yog qhov zoo tshaj plaws los xaiv cov khoom siv nrog cov lo ntsiab muag sib hloov lossis kho lub teeb lub kaum sab xis.
Cov ntsiab lus
Lub hauv paus ntsiab lus tseem ceeb rau kev xaiv lub kaum sab xis ntawm qhov chaw ua si kis las muaj xws li:
Ntau txoj haujlwm mounting thiab qhov projection ntev dua yuav tsum tau nqaim beam kaum sab xis; qis mounting txoj hauj lwm thiab luv luv nrug yuav tsum wider beam kaum.
Cov kis las sib txawv thiab kev teeb tsa ncej hu rau qhov sib txawv ntawm kev sib txuas ntawm lub kaum sab xis.
Rau qhov chaw loj, kev sib xyaw ntawm lub kaum sab xis yog pom zoo es tsis txhob cia siab rau ib lub kaum ntse ntse.
Beam xaiv lub kaum sab xis yuav tsum sib npaug sib npaug, tswj qhov ci ntsa iab, thiab lub teeb tawg; brightness yuav tsum tsis yog ib qho tseem ceeb.
Cov qauv tsim kawg yuav tsum raug txheeb xyuas siv cov teeb pom kev zoo simulation software ua ntej mus rau ntawm -qhov chaw aiming thiab kho.
Raws li cov ntaub ntawv no, peb cov engineers yuav muab cov lus pom zoo ntawm lub kaum sab xis thiab cov phiaj xwm teeb pom kev zoo, kom ntseeg tau tias koj cov peev nyiaj siv tau zoo. Thov tso lus los yog xa ib qho kev nug, thiab peb yuav tau rov qab rau koj sai li sai tau.
