Thaum mus yuav cov teeb pom kev nyab xeeb, ntau tus neeg siv khoom thawj lo lus nug feem ntau yog, "Lub teeb no tuaj yeem ncav cuag li cas?" Thaum lo lus nug zoo li yooj yim, cov lus teb tsis ncaj ncees. Ob qhov sib txawv200W dej nyab teebtuaj yeem ua tau cov txiaj ntsig sib txawv: ib tus tuaj yeem tsim cov kab teeb pom kev meej tshaj 100 meters, thaum lwm qhov kev tawm tsam kom ncav cuag 50 meters, ua rau cov nqaj tsis muaj zog, diffused beam. Dab tsi ua rau qhov sib txawv no? Qhov kev ncua deb tsis yog txiav txim los ntawm ib qho parameter; es, nws yog qhov tshwm sim ntawm kev sib cuam tshuam ntawm cov khoom xws li lumens, beam angle, mounting height, thiab optical design. Kab lus no rhuav tshem cov kev hloov pauv no los pab koj txiav txim siab seb lub teeb dej nyab tshwj xeeb puas tau raws li koj qhov kev xav tau teeb pom kev zoo.
Cov Ntsiab Lus Tseem Ceeb Txiav Txim Qhov Kev ncua deb
Qhov kev ncua deb tsis tuaj yeem xam raws li wattage ib leeg; Koj yuav tsum xav txog kev sib xyaw ua ke ntawm cov ntsuas hauv qab no:
Lumens: Qhov no sawv cev rau qhov tseeb luminous flux (lub teeb tso zis) ntawm lub fixture. Wattage qhia tias siv zog, tsis ci ntsa iab. Ob lub teeb nrog tib qhov kev ntsuas 200W-tab sis siv cov chips sib txawv thiab kev teeb tsa tsav tsheb- tuaj yeem sib txawv hauv lumen tso zis ntau dua 30%.
Beam Angle: Lub kaum sab xis nqaim kom pom lub teeb, txuas ntxiv qhov kev ncua deb; lub kaum sab xis dav npog thaj tsam loj dua tab sis txo cov nqaj lub zog nkag mus. Qhov no yog vim li cas nqaim - lub kaum ntse ntse dej nyab feem ntau hu ua "searchlight-style" fixtures.
Reflector / Lens Tsim: Nrog tib lub teeb ci LED, ua ke nrog lub teeb pom kev zoo parabolic piv rau lub lens tiaj tus qauv tuaj yeem ua rau muaj qhov sib txawv tseem ceeb hauv qhov projection deb. Kev tsim kho qhov muag zoo tshaj plaws zoo sib sau ua ke lub teeb tawg mus rau hauv lub teeb tsom, muaj zog.
Mounting Qhov siab thiab lub kaum sab xis: Ib txoj hauj lwm mounting ntau dua theoretically tsub kom lub vojvoog npog; Txawm li cas los xij, yog tias lub kaum sab xis tsis raug kho kom raug, txawm tias lub teeb muaj zog tuaj yeem ua rau tsis pom lub hom phiaj.
Environmental Factors: Smog, plua plav, thiab av noo attenuate light. Yog li ntawd, qhov sib txawv ntawm cov ntaub ntawv kuaj sim thiab qhov tseeb ntawm - qhov ua tau zoo ntawm qhov chaw feem ntau loj dua li qhov xav tau.
Kwv yees Illumination Range rau Floodlights ntawm Ntau Wattages
Cov kab hauv qab no ua raws li cov lus qhia raws li tus qauv luminous efficiency (kwv yees . 130-150 lm/W) thiab nruab nrab beam kaum sab xis (nyob ib ncig ntawm 60℃). Lawv tsuas yog npaj rau kev ntsuam xyuas ua ntej thaum xaiv cov khoom; Kev ua tau zoo tiag tiag yuav tsum tau txheeb xyuas cov ntaub ntawv ntsuas:
Nyob ib ncig ntawm 50W: Haum rau me me - thaj tsam teeb pom kev zoo nrog thaj tsam ntawm kwv yees li 20-30 meters; feem ntau yog siv rau lub tshav puam thiab cov chaw cia khoom me me.
Nyob ib ncig ntawm 100W: Muaj ntau yam ntawm kwv yees li 40-50 meters; haum rau me me - mus rau - chaw nres tsheb nruab nrab thiab cov tsev hais plaub ntaus pob.
Nyob ib ncig ntawm 200W: Muaj peev xwm npog 60-80 meters; feem ntau pom nyob rau hauv cov pej xeem loj squares, thaj chaw Hoobkas, thiab sab nraum zoov freight yards.
400W thiab siab dua: Feem ntau yog siv rau loj- nplai, siab- mast teeb pom kev zoo xws li chaw ntau pob, chaw nres nkoj, thiab qhov chaw mining. Kev siv tau zoo tuaj yeem ncav cuag 100 meters lossis ntau dua, txawm hais tias qhov no feem ntau yuav tsum tau nqaim beam kaum sab xis thiab siab - mast mounting.
Nws yuav tsum tau muab sau tseg tias cov nuj nqis no sawv cev rau kev lag luam siv ntau yam. Cov kev hloov pauv tseem ceeb hauv kev ua tau zoo luminous thiab kev tsim kho qhov muag muaj nyob ntawm cov tuam txhab, lub ntsiab lus tib lub wattage tsis tau lees tias tib lub teeb pom kev zoo.
Beam Angle: Ntsuas qhov nrug thiab thaj chaw npog
Qhov zoo tshaj plaws no feem ntau saib xyuas los ntawm cov neeg siv khoom, tab sis nws yog qhov tseem ceeb thaum xaiv lub teeb.
Lub kaum sab xis nqaim (piv txwv li, 10℃-30 degree) mloog zoo rau lub teeb nyob rau hauv ib qho chaw me me, ua rau muaj kev cuam tshuam ntau dua thiab ua kom pom tseeb. Lawv zoo tagnrho rau cov ntawv thov uas xav tau ntev - qhov projection ntev, xws li ntauwd cranes, kev soj ntsuam ciam teb, thiab siab -mast teeb pom kev zoo hauv thaj chaw mining. Txawm li cas los xij, qhov tsis zoo yog txwv kev pab; ib lub teeb tawm tsam kom pom qhov chaw loj tag nrho.
Lub kaum sab xis dav (piv txwv li, 90℃-120 degree) muab cov yam ntxwv sib txawv: qhov dav dav haum rau cov chaw nres tsheb thiab cov chaw pej xeem uas nyiam qhov teeb pom kev zoo ntev dua -kev nkag mus, txawm hais tias qhov cuam tshuam tau zoo raug txo qis.
Hauv cov haujlwm tiag tiag, kev sib xyaw- lub kaum sab xis feem ntau yog ua haujlwm- piv txwv li, siv dav - lub teeb lub kaum sab xis hauv qhov chaw rau kev pom dav dav thaum siv nqaim - lub kaum sab xis ntawm ob sab los txhawb qhov ci ntawm qhov deb. Cov tswv yim no ua kom muaj kev sib haum xeeb yam tsis muaj kev cuam tshuam cuam tshuam.
Yuav Ua Li Cas Xaiv Lub Teeb Raws Li Qhov Tseeb
Ua ntej xaiv lub teeb, nws yog ib qho tsim nyog yuav tsum tau qhia txog peb yam tseem ceeb thiab sab laj txog cov kev qhia tshwj xeeb:
Qhov chaw thiab cov duab: Puas yog qhov chaw ntev thiab nqaim, lossis qhov dav, qhib square? Ntev, nqaim qhov chaw (xws li khiav lem lossis wharf frontages) yog qhov zoo dua rau kev sib xyaw ua ke ntawm siab -wattage teeb nrog cov kab nqaim, qhov chaw square tau txais txiaj ntsig los ntawm cov kab teeb dav dav rau kev teeb pom kev zoo dua.
Kev teeb tsa qhov siab txwv: High-mast installations tso cai rau siab -wattage, nqaim{2}} lub teeb lub kaum ntse ntse kom ua tiav qhov ntev - thaj tsam. Hloov pauv, yog tias qhov siab ntawm kev teeb tsa yog txwv (piv txwv li, mounting ntawm phab ntsa lossis qis brackets), nrhiav cov wattage siab yog qhov tsis muaj txiaj ntsig; Hloov chaw, qhov tseem ceeb yuav tsum tau muab rau beam angle thiab optical efficiency.
Illuminance uniformity tseev kom muaj: Kev ruaj ntseg thiab kev soj ntsuam cov xwm txheej feem ntau xav tau teeb pom kev zoo ib yam tsis pom qhov tsaus ntuj. Nyob rau hauv qhov sib piv, ntev - teeb ceeb toom teeb pom kev zoo (xws li rau ntauwd cranes lossis siab -altitude operations) ua qhov tseem ceeb rau kev pom ntawm qhov deb tshaj plaws, ua rau cov kev xav tau sib xws kuj qis dua.
Cov teeb meem tshwm sim thaum yuav khoom
Tsom ntsoov rau wattage thaum tsis quav ntsej lumens: Raws li tau hais dhau los, cov wattage siab tsis sib npaug rau qhov ci ntsa iab; ib txwm txheeb xyuas qhov tseeb luminous efficiency (lm/W).
Overlooking lumen depreciation: Qee tus nqi qis- cov khoom lag luam tus nqi yuav tshwm sim thaum pib tab sis raug kev txom nyem los ntawm kev tswj xyuas tsis zoo. Tom qab rau lub hlis ntawm kev siv, qhov tseem ceeb lumen depreciation tshwm sim, drastic txo qhov zoo illumination ntau yam.
Kev ua yuam kev cov ntaub ntawv hauv chav kuaj rau qhov tiag- kev ua haujlwm hauv ntiaj teb: Cov neeg tsim khoom 'illumination range specifications feem ntau yog raws li cov xwm txheej zoo. Hauv cov phiaj xwm tiag tiag, cov npoo kev nyab xeeb yuav tsum tau muab tso rau hauv, tshwj xeeb tshaj yog rau cov chaw lag luam uas muaj smog lossis plua plav.
Xaiv lub kaum sab xis tsis ncaj ncees lawm: Hais txog kev lag luam - tawm ntawm qhov nqaim thiab dav - yog tias qhov kev xav tau ntawm qhov chaw tsis tau hais meej meej thaum lub sij hawm xaiv, nrhiav kev ncav cuag tsis txaus lossis tsis sib xws tom qab kev teeb tsa ua rau cov nqi rov ua haujlwm siab.
Cov ntsiab lus
Lo lus nug ntawm "yuav ua li cas deb lub teeb ci tuaj yeem ci" tsis tuaj yeem teb nrog ib daim duab; Nws yog qhov tshwm sim ntawm kev sib cuam tshuam ntawm lumen tso zis, beam kaum sab xis, kho qhov muag tsim, thiab teeb tsa kev teeb tsa. Es tsis txhob kho ib leeg ntawm wattage thaum xaiv, ua ntej qhia qhov chaw ntawm qhov chaw, qhov siab qhov siab, thiab cov kev xav tau sib xws. Tom qab ntawd, sib phim cov khoom raws li cov ntaub ntawv muaj txiaj ntsig zoo. Txoj hauv kev no yuav pab kom tsis txhob muaj qhov tsis txaus ntseeg uas koj them tus nqi them rau lub teeb uas tsis ncav cuag thaj chaw lub hom phiaj lossis muab qhov ci txaus tab sis tsis txaus.
Yog tias koj tab tom xaiv cov teeb pom kev zoo rau ib qhov project tshwj xeeb thiab tsis paub meej txog qhov tsim nyog wattage lossis beam lub kaum sab xis, thov koj xav qhia rau peb lub vev xaib qhov ntev, qhov siab, thiab teeb pom kev zoo nrog peb. Raws li cov kev txwv no, peb tuaj yeem muab cov lus pom zoo ntawm cov khoom lag luam ua ntej thiab suav cov teeb pom kev zoo, nrog rau cov ntaub ntawv ntsuas tiag tiag rau koj siv. Koj tuaj yeem tiv tauj peb nrog koj cov lus nug txhua lub sijhawm.
