HAUJ LWM NTAWM LUB CHAW UA HAUJ LWM?

Chaw nres tsheb teeb pom kev zoo yog hais txog cov teeb pom kev sab nraum zoov uas muab teeb pom kev zoo rau cov chaw nres tsheb, txoj hauv kev, txoj kev thiab cov neeg taug kev taug kev. Feem ntau ntawm cov chaw nres tsheb yog mounted rau cov ncej kom npog thaj tsam loj teeb pom kev zoo. Kev xav tau rau ntau qhov chaw teeb pom kev zoo sib txawv ntawm ib leeg. Chaw nres tsheb lub teeb yuav tsum ua kom xis nyob yam tsis ua rau qhov muag. Kev Paub Txog Qhov Kev Pabcuam Ntawm Qhov Chaw Nres Tsheb yog qhov tseem ceeb rau qhov chaw ua haujlwm nyab xeeb rau cov neeg siv khoom lossis cov neeg ua haujlwm. Thaum ua haujlwm hauv qhov chaw nres tsheb, muaj kev pheej hmoo ntawm kev phom sij lossis teeb meem kev nyab xeeb hauv qhov chaw nres tsheb. Yog li ntawd, nws yog ib qho tseem ceeb heev kom muaj teeb pom kev zoo hauv cheeb tsam no.

Hom Lens yog Transmissive Optical Device uas cuam tshuam rau lub teeb pom kev ntawm lub teeb los ntawm kev cuam tshuam. Lub lens yooj yim muaj xws li ib qho khoom siv, thaum lub lens compound muaj ob peb lo ntsiab muag yooj yim feem ntau yog ib qho axis ntev. Optics lens yog qhov tseem ceeb hauv txhua qhov chaw nres tsheb teeb tsim. LED lo ntsiab muag tuaj nyob rau hauv ntau yam duab thiab ntau thiab tsawg, xws li puag ncig, square thiab hexagonal. Cov ntaub ntawv lo ntsiab muag muaj xws li yas thiab silicone. Yog li ntawd ib txhia yog nruj thiab ib txhia yog hloov tau. Hom 3 LED lo ntsiab muag yog tsim los siv nrog ib leeg lossis ntau yam LEDS rau qhov chaw nres tsheb teeb pom kev zoo. Lawv zaum dhau ntawm LEDs los tsim cov teeb pom kev zoo uas xav tau. Ntau yam khoom ntawm hom 3 lo ntsiab muag ua kom muaj kev tswj xyuas meej ntawm cov kab teeb ntawm lub teeb. LED hom 3 lo ntsiab muag tuaj yeem muab qhov zoo nkauj zoo nkauj los ntawm kev npog cov khoom siv hauv LED. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias optics nrog zoo tib yam saib lub kaum ntse ntse tuaj yeem sib txawv ntau hauv kev siv thiab qhov zoo ntawm cov nqaj nyob ntawm qhov emitters ntawm qhov tsim kho qhov muag.

Mounting qhov siab rauqhov chaw nres tsheb teebtuaj yeem nyob ntawm 12 taw mus rau 20 ko taw, tab sis qee zaum, cov ncej tuaj yeem nce mus txog 35 ko taw. Qhov loj ntawm qhov chaw nres tsheb txiav txim siab qhov siab pom zoo ntawm kojncej teeb. 

Nws raug pom zoo kom muaj 2 LED Chaw nres tsheb teeb lub taub hau ntawm 20, 000 lumens txhua ntawm li 15-20 ko taw siab ntawm txhua tus ncej. Muab cov ncej sib nrug li 20 feet. Qhov no yog qhov nruab nrab teeb pom kev zoo. Txawm li cas los xij, nrog rau qhov chaw nres tsheb sib txawv, koj tuaj yeem txiav txim siab seb lub teeb uas koj xav tau rau koj qhov chaw nres tsheb, los ntawm kev tsom mus rau cov taws tswm ciab rau hauv av thiab sib xws. Footcandle ntsuas tus nqi ntawm lub teeb uas ncav cuag thaj chaw. Lub teeb uniformity yog qhia raws li qhov piv ntawm qhov siab tshaj plaws- mus rau yam tsawg kawg nkaus illumination theem. Tam sim no, cov lus pom zoo tshaj plaws rau feem ntau cov chaw nres tsheb sab nraum zoov yog 3: 1. Yeej, thaum lub teeb pom kev tsis sib xws, nws yog vim qhov chaw nruab nrab ntawm cov khoom siv. Feem ntau, lwm yam nta, xws li ntoo cuam tshuam rau qhov sib xws.

Hom ncej koj siv ntawm koj qhov chaw nres tsheb kuj tseem yuav txiav txim seb lub teeb uas koj siv ntawm koj qhov chaw nres tsheb. Mounting qhov siab rau qhov chaw nres tsheb tuaj yeem nyob ntawm 12feet mus rau 20 ko taw, tab sis qee zaum, cov ncej tuaj yeem mus siab li 35 feet. Qhov loj ntawm qhov chaw nres tsheb txiav txim siab qhov siab ntawm koj tus ncej. Rau thaj tsam loj dua, cov ncej siab yog nyiam, thiab rov ua dua. Thaum koj txiav txim siab qhov siab ntawm tus ncej siv, ces koj tuaj yeem txiav txim siab ntawm qhov sib nrug ntawm koj cov khoom siv. Txoj cai ntawm tus ntiv tes xoo raws li qhov no yog kev txhawj xeeb yog: qhov siab dua qhov siab, qhov tsawg dua tus ncej koj xav tau.

i. Tsis yog, tsim kom muaj cov qauv zoo sib xws. Tej zaum lawv yuav ci dua tab sis tsis tas li ntau thaj chaw

Kev siv cov teeb pom kev zoo LED tsis npog ntau qhov chaw es; LED fixtures pab koj tsim ib qho kev teeb tsa rau koj qhov chaw nres tsheb uas muab lub teeb pom kev zoo. LED teeb pom kev zoo muaj cov qauv uas thaum tso rau ntawm ib qho khoom lossis qhov chaw txhais tau tias lub teeb tawg ntawm lub teeb pom kev zoo li cas. Nws yog txiav txim los ntawm qhov taw tes ntawm qhov uas 50 feem pua ​​​​ntawm cov khoom siv luminous siv tau ntsib. Cov kev faib tawm no yog qhov kev xaiv zoo tshaj plaws rau qhov chaw nres tsheb teeb pom kev zoo. 5 hom kev faib tawm txawv yog- Hom I, Hom II, Hom III, Hom IV thiab Hom V lub teeb faib.

Lub Teeb Txawv Distributions

Hom I qauv muab lub teeb dav, sib luag rau cov khoom siv nyob rau hauv nruab nrab ntawm txoj kev taug kev.

Hom II lub teeb fixtures muaj qhov sib faib qis me ntsis thiab yog npaj rau kev teeb tsa qhov twg cov khoom siv tau muab tso rau ntawm sab ntawm txoj kev lossis txoj kev teeb pom kev zoo. Kuj pom Txoj Kev Teeb Pom Kev mount thiab thaiv cov ntaub ntawv ntawm no

Hom III lub teeb faib miv lub teeb txog 2.75 npaug dav dua li qhov siab ntawm qhov teeb tsa.

Hom IV lub teeb faib fixtures tseem hu ua asymmetrical fixtures. Zoo li hom III, cov teeb pom kev zoo no cam khwb cia lub teeb 2.75 dav dua lawv qhov siab tab sis tsim cov qauv sib npaug ntau dua uas thawb lub teeb tawm sab nraud, nrog lub teeb me ntsis poob qab lub teeb.

Hom V lub teeb faib fixtures yog omnidirectional fixtures. Lawv faib lub teeb nyob rau hauv ib tug niaj hnub los yog lub voj voog nyob ib ncig ntawm lub fixture.

Qhov chaw nres tsheb ntau tshaj plaws yog T3, luv luv rau Hom III yog tus qauv defacto uas tau nyob ib puag ncig ntau xyoo. Nyob rau hauv lub teeb hom kab ntawv hauv qab no, 140 degrees dav thiab 90 degrees rau pem hauv ntej, ntawm 20 ko taw siab uas yog hais txog 46 ko taw dav thiab 28 ko taw rau pem hauv ntej.

Lub teeb 300 watt, uas tshwm sim rau NextGen II 300 watt, ntawm 30 feet siab zoo li peb muaj hauv qab no. Cov lej nyob rau hauv lub voj voog yog cov footcandles. Nco ntsoov tias 150 watt ntawm tib qhov kev ua tau zoo yuav yog ib nrab ntawm tus lej no. Lub teeb ntawm ib nrab qhov siab, 15 ko taw, yuav yog ib nrab ntawm qhov kev pabcuam no.

 

Koj tuaj yeem pom qhov twg footcandles poob. Qhov no yuav pab peb txiav txim siab seb qhov twg yuav xav tau lub teeb tom ntej. Hauv qhov piv txwv saum toj no, 30 ko taw siab, koj tuaj yeem pom koj yuav xav tau lub teeb tom ntej txog 30 ko taw kom tswj tau ib qho txawm 8feet tswm ciab raws qhov ncab. Yog tias koj tsis mloog qhov chaw tsaus nti hauv nruab nrab, koj tuaj yeem mus 40-50 ko taw deb tab sis nws txhais tau tias koj yuav mus ntawm 7fc mus rau 2fc thiab rov qab mus rau 7. Qhov zoo rau rov qab ntau ntau, koj tsis heev uniform kom haum chaw nres tsheb teeb pom kev zoo.

Ib cheeb tsam chaw nres tsheb yog xam los ntawm kev sib npaug ntawm qhov chaw nres tsheb qhov square footage los ntawm qhov yuav tsum tau ua footcandle. Piv txwv li, qhov chaw nres tsheb ntawm 100 square feet, uas xav tau 20 footcandles, yuav xav tau 2, 000 lumens.

Koj yuav tsum tau them sai sai rau wattage lumens thiab footcandles. LED teeb muab ntau lumen tso zis ib watt. Rau kev teeb pom kev zoo, qhov no yog qhov tseem ceeb. Yog tias koj xav kom lub teeb npog 15 mus rau 20 ko taw nws yog qhov zoo tshaj los nrhiav 16000-20000 lumens. Ntawm qhov tod tes, yog tias koj xav npog 20 mus rau 30 ko taw, 40000 lumen teeb yog qhov kev xaiv zoo tshaj plaws. Yog li ntawd, thaum nrhiav LED qhov chaw nres tsheb teeb, koj lub hom phiaj yuav tsum yog ntawm lumens. Lub ci ci ntawm LEDs yog txiav txim siab los ntawm lumens. Lumen yog ib chav ntsuas ntawm qhov ci ci uas muab los ntawm lub teeb thaum lub watt yog qhov ntsuas ntawm lub zog npaum li cas lub teeb kos.

Footcandles yog chav ntsuas feem ntau siv los xam cov teeb pom kev hauv qhov chaw sab nraum zoov. Ib tug ko taw-teeb tswm ciab tuaj yeem txhais tau tias yog qhov luminance ntawm ib qho square feet ntawm qhov chaw teeb pom kev zoo. Yog li, nws yog ib qho kev ntsuas ntawm lub teeb uas ncav cuag thaj tsam ntawm qhov chaw. Los ntawm lub teeb taws tswm ciab, lub teeb poob ntawm ib square feet ntawm cheeb tsam sib npaug ib lumen ib square feet. Lub activeness ntawm ib cheeb tsam yog lub ntsiab determinant rau lub teeb txaus. Cov kws paub txog teeb pom kev zoo pom zoo kom pom qhov tsawg kawg nkaus ntawm 1 fc thoob plaws thaj chaw uas xav tau thiab 2 txog 4 fc yog qhov tsim nyog rau kev thov rov hais dua thiab pom kev pom zoo.
