Qhov teeb meem ntawm chav kawm teeb pom kev zoo hauv tsev kawm theem pib thiab theem nrab hauv kuv lub tebchaws
Tam sim no, feem ntau ntawm cov chav kawm teeb pom kev zoo hauv cov tsev kawm theem qis thiab nruab nrab hauv peb lub tebchaws siv cov raj fluorescent los ua lub teeb, lossis siv ncaj qha rau txoj kev ntawm" tube brackets (suav nrog cov khoom siv hluav taws xob) + cov raj raug [GG ] quot;, los yog siv" teeb (daim phiaj teeb vaj huam sib luag/blackboard teeb) )+Fluorescent raj teeb qhov chaw" txoj hauv kev los xaus qhov yooj yim teeb pom kev zoo thiab blackboard teeb pom kev hauv chav kawm
Hom teeb pom kev zoo no feem ntau muaj teeb meem hauv qab no:
1) Lub rooj illuminance yog dav tsis muaj. Raws li kev soj ntsuam teeb pom kev zoo ntawm 99 lub tsev kawm ntawv hauv rau thaj tsam ntawm peb lub teb chaws, qhov ntsuas qhov pom ntawm cov chav kawm feem ntau yog nruab nrab ntawm 200lx thiab 300lx, cov teeb pom kev zoo sib xws yog 232lx, thiab qhov tseeb illuminance thiab kev npaj illuminance yog ob qho tib si qis.
2) Lub teeb pom kev zoo ntawm lub teeb pom kev zoo yog qhov tsis zoo. Feem ntau, cov raj fluorescent (los yog nrog cov reflectors) yog siv los ua cov teeb dub. Sab saum toj ntawm lub blackboard yog ci heev, uas ua rau nws yooj yim rau cov tub ntxhais kawm paub qhov txawv ntawm cov xim dawb chalk nyob rau sab sauv ntawm lub blackboard, thaum lub hauv qab yog tsaus heev thiab tsis muaj illumination, thiab cov tub ntxhais kawm ntawv tsis pom cov ntsiab lus sau. .
3) Glare yog pom tseeb yooj yim los cuam tshuam qhov muag. Lub teeb pom kev dav dav ntawm chav kawm siv lub teeb lub raj bracket + fluorescent tube txoj kev. Lub teeb qhov chaw raug nthuav tawm. Cov tub ntxhais kawm tsuas pom qhov teeb pom kev ncaj qha thiab lawv qhov muag raug cuam tshuam. Kev siv cov grille teeb vaj huam sib luag yuav zoo dua, tab sis nws tseem tsis tuaj yeem tiv thaiv tag nrho. Yog tias lub teeb pom kev dub ncaj qha siv lub raj fluorescent, cov tub ntxhais kawm thiab cov kws qhia ntawv yuav raug cuam tshuam los ntawm qhov ci ntsa iab, uas yuav cuam tshuam rau kev kawm lub zog. Yog hais tias lub reflector ntxiv, txawm hais tias qhov ci ntsa iab tuaj yeem tiv thaiv los ntawm cov tub ntxhais kawm, qhov cuam tshuam ntawm qhov ci ntsa iab yuav ua rau cov kws qhia ntawv hnyav dua.
4) Cov xim kub kub tuaj yeem ua rau pom kev qaug zog. Ntau chav kawm tseem siv cov raj fluorescent nrog cov xim kub ntawm 6500K. Cov kev tshawb fawb tau pom tias txawm hais tias qhov kub thiab txias teeb pom kev zoo tuaj yeem ua rau tib neeg saib xyuas thiab ceev faj ua ntej, qhov ntev ntawm cov xim kub kub teeb pom kev zoo tuaj yeem ua rau pom kev qaug zog thiab ua rau lub hlwb qaug zog. Yog li ntawd, cov txiaj ntsig ntawm kev rov qab mus ntev tsis zoo, thiab nws tuaj yeem ua rau muaj kev xav tsis zoo xws li kev ntxhov siab thiab kev qias neeg tshwm sim hauv lub siab.
2. Kev siv LED blackboard lub teeb ntse teeb pom kev zoo
1) Thaum tag nrho cov luminous flux ntawm txhua lub teeb vaj huam sib luag ntawm peb-dimensional teeb pom kev zoo LED blackboard teeb vaj huam sib luag yog 3000lm, illuminance persistence tus nqi (kev tu coefficient yog 0.8) nyob rau hauv 0.75m kab rov tav dav hlau (qhov siab ntawm chav kawm ntawv lub rooj) 7. 0m X 5. 6m ntawm cov tub ntxhais kawm lub rooj cheeb tsam 336lx, illuminance uniformity tuaj yeem ua tiav 0.82. Lub teeb pom kev zoo peb sab LED teeb vaj huam sib luag nrog sab-emitting thiab rov qab-emitting teeb pom kev zoo muaj ib qho zoo heev embodiment nyob rau hauv ua kom lub uniformity ntawm peb-dimensional qhov chaw teeb pom kev zoo thiab txo qhov chaw glare nyhuv.
2) Tom qab simulation tsom xam, peb-dimensional teeb pom kev zoo LED blackboard teeb vaj huam sib luag yog zoo heev nyob rau hauv ntxiv cov uniformity ntawm peb-dimensional teeb pom kev zoo. Raws li lub hauv paus no, nws tau tshaj tawm cov teeb pom kev zoo ntawm LED teeb pom kev zoo, ua ke nrog LED blackboard teeb thiab cov kev tswj xyuas ntse los tsim lub teeb pom kev zoo ntawm LED, thiab sim cov cuab yeej hauv chav kawm uas ua raws li qhov xwm txheej. Thaum lub teeb pom kev zoo raug hloov kho rau hom kev qhia ib txwm muaj, lub teeb pom kev dub thiab lub teeb pom kev zoo ntawm LED vaj huam sib luag tau teeb ua ke, thiab xim kub hloov kho rau 4000K. Raws li cov txiaj ntsig tau los ntawm Dialux scene teeb pom kev zoo simulation, LED blackboard lub teeb ntse teeb pom kev zoo tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm txhua tus qauv illuminance thiab uniformity ntawm chav kawm teeb pom kev zoo.
Raws li qhov chaw uas cov tub ntxhais kawm nyob thiab kawm tau ntev, ib puag ncig lub teeb pom kev zoo ua lub luag haujlwm zoo los txhawb kev loj hlob ntawm cov tub ntxhais kawm theem pib thiab theem nrab. Peb txoj kev npaj lub teeb pom kev zoo, kev npaj cov khoom lag luam sib luag thiab cov phiaj xwm ntse LED tau xaus qhov kev txhim kho cov teeb pom kev zoo hauv chav kawm. Tom qab siv tau thiab ua pov thawj hauv qee qhov kev sim hauv chav kawm, nws yog qhov tseeb tias lub teeb pom kev zoo ntawm LED blackboard lub teeb npaj los ntawm tus sau tau txhim kho kev qhia zoo, tus kws qhia ntawv thiab cov tub ntxhais kawm pom kev paub, cov tub ntxhais kawm rov qab, thiab txo qis kev siv hluav taws xob.
