Vim li cas Glare yog qhov teeb meem zais hauv chaw ua haujlwm teeb pom kev zoo
Taug kev mus rau hauv yuav luag txhua qhov chaw ua haujlwm niaj hnub no thiab koj yuav pom LED vaj huam sib luag teeb nyob rau saum taub hau - tab sis tsis yog txhua lub vaj huam sib luag tsim sib npaug. Qhov sib txawv ntawm cov neeg yuav khoom pom thawj zaug tsis yog qhov ci ntsa iab tab sis kev nplij siab: qee qhov luminaires ua rau mob taub hau thiab kev tshuaj ntsuam xyuas tom qab ob peb teev, thaum lwm tus xav tias tsis muaj zog txawm tias nyob rau hauv tag nrho cov teeb pom kev zoo. Qhov sib txawv ntawd yog ntsuas los ntawm Unified Glare Rating, lossis UGR. Rau ib qho LED vaj huam sib luag teeb destined rau chaw ua hauj lwm teeb pom kev zoo, kev nkag siab UGR yog ib qho tseem ceeb tshaj specification tom qab cov zis photometric yooj yim. Phau ntawv qhia no piav qhia txog UGR txhais li cas, nyeem nws li cas, thiab yuav ua li cas lub npe nrov LED teeb pom kev zoo tsim cov vaj huam sib luag uas sib npaug qis glare nrog kev ua tau zoo thiab kav ntev.
IP65- ntsuas UGR LED vaj huam sib luag teeb los ntawm Luxsky Teeb pom kev zoo - tsim los rau qhov chaw ua haujlwm glare thiab chaw lag luam
UGR txhais li cas thiab Yuav Nyeem Cov Naj Npawb li cas
UGR yog qhov ntsuas ntsuas thoob ntiaj teb (CIE 117) uas kwv yees tias qhov tsis xis nyob ntau npaum li cas lub teeb pom kev teeb pom kev zoo yuav ua rau tus neeg soj ntsuam. Qhov ntsuas tau los ntawm kwv yees li 10 mus rau 30, nrog cov lej qis dua txhais tau tias tsis tshua pom. Hauv kev xyaum, cov phiaj xwm phiaj xwm kom huv si rau qhov tiag - ntiaj teb cov cai:
- UGR Tsawg dua lossis sib npaug rau 16:haum rau kev kos duab chaw ua haujlwm thiab ua haujlwm pom tseeb
- UGR Tsawg dua lossis sib npaug rau 19:lub qab nthab pom zoo rau cov chaw ua haujlwm dav dav thiab cov chav sib tham
- UGR Tsawg dua lossis sib npaug rau 22:txais tau rau thaj chaw muaj thiab kev ncig uas cov ntxaij vab tshaus tsis tshua muaj zog
- UAS > 25:feem ntau glaring rau cov rooj ua haujlwm ruaj khov - feem ntau nyob rau hauv cov laus lossis cov khoom siv tsis zoo
Qhov kev ntsuam xyuas nyob ntawm peb yam: lub luminaire lub luminance, nws qhov loj thiab txoj hauj lwm txheeb ze rau tus saib, thiab qhov ci ntsa iab ntawm ib puag ncig ib puag ncig. Qhov no yog vim li cas lub vaj huam sib luag uas zoo nkaus li zoo rau ntawm chav ua yeeb yam qab nthab tseem tuaj yeem ua tsis tiav hauv qhov chaw ua haujlwm tiag tiag - lub geometry ntawm chav tsev thiab qhov cuam tshuam ntawm phab ntsa thiab cov rooj zaum hloov qhov kawg tshwm sim. Thaum cov lus qhia tshwj xeeb hu rau UGR < 19 LED vaj huam sib luag teeb, lub luminaire yuav tsum tau tsim nrog kev sib sib zog nqus optic tswj, diffusers, los yog micro- prismatic lo ntsiab muag uas ua kom lub luminous nto los ntawm kev ua ib lub teeb duab plaub nyob rau hauv qhov kev pom.
Tshaj UGR: IP, CRI, thiab xim kub
Glare tsuas yog ib qho ntawm plaub qhov tshwj xeeb uas txiav txim siab seb lub teeb vaj huam sib luag puas haum rau nws ib puag ncig. Kev tiv thaiv yog qhov thib ob: IP65- ntsuas LED vaj huam sib luag lub teeb yog kaw nrog plua plav thiab dej dav hlau, ua rau nws muaj kev cia siab rau cov chav ua noj, chav dej, ntxhua khaub ncaws, npog cov kev taug kev, thiab lwm qhov chaw ntub dej uas tus qauv IP20 vaj huam sib luag yuav ua tsis tiav ntxov. Qhov thib peb yog xim rendering: rau cov chaw ua haujlwm, CRI (Color Rendering Index) ntawm 80 yog qhov tsawg kawg nkaus kev cai lij choj hauv ntau lub khw, thaum 90+ tau nce ntxiv rau cov qauv tsim, chaw kho mob, thiab chav ua yeeb yam uas muaj xim tiag tiag. Plaub yog sib txheeb xim kub - 4000K nruab nrab dawb tseem yog qhov chaw ua haujlwm, thaum 5000K haum rau kev lag luam thiab 3000K tsim kom muaj cua sov, ntau qhov chaw so hauv chaw tos txais thiab lounges.
Ib Daim Ntawv Qhia Txog Kev Xaiv Rau Cov Pab Pawg Muag Khoom
Thaum ntsuam xyuas lub teeb ci LED vaj huam sib luag rau lub teeb pom kev hauv chaw ua haujlwm, ua haujlwm los ntawm daim ntawv teev npe luv luv es tsis yog piv cov wattage ib leeg - thiab thaum shortlisting LED vaj huam sib luag teeb rau lub teeb pom kev hauv chaw ua haujlwm, thov cov ntaub ntawv pov thawj photometric es tsis yog kev lag luam thov:
- Paub meej tias tus nqi UGR yog teev rau qhov siab mounting qhov siab - UGR < 19 ntsuas ntawm 3 meters yuav tsis tuav ntawm 2.4 meters
- Tshawb xyuas kev tiv thaiv kev tiv thaiv ib puag ncig tiag: IP44 rau kev siv sab hauv tsev, IP65 rau thaj chaw ntub dej lossis plua plav
- Tshawb xyuas cov neeg tsav tsheb zoo thiab flicker: siab- cov neeg tsav tsheb zoo tshem tawm cov flicker pom, tiv thaiv cov neeg ua haujlwm kev nplij siab thiab txo qhov muag pom
- Daim ntawv pov thawj kev thov: UL / ETL / CE cov cim thiab LM-79 daim ntawv qhia txog duab qhia tias cov duab tau raug txheeb xyuas ntawm nws tus kheej
- Nug txog kev lees paub thiab kev saib xyuas lumen - ib lub chaw tsim khoom muaj npe yuav ua rau L70 kev ntsuas lub neej ntawm 50,000 teev lossis ntau dua
Rau siab -zoo, muaj ntawv pov thawj cov kev daws teeb meem, tshawb xyuas qhovLED vaj huam sib luag teebNtau yam los ntawm Luxsky Teeb pom kev zoo, UL ETL tau ntawv pov thawj LED teeb pom kev zoo hauv Shenzhen.
Xaus
Xaiv lub chaw ua haujlwm LED vaj huam sib luag lub teeb tsis yog ib qho teeb meem ntawm kev xaiv qhov ci ntsa iab ntawm tus nqi qis tshaj. UGR txiav txim siab seb cov neeg nyob hauv qhov chaw nyob zoo li cas, qhov kev ntsuam xyuas IP txiav txim siab seb qhov khoom puas muaj sia nyob nws ib puag ncig, thiab CRI ntxiv rau xim kub txiav txim seb qhov chaw zoo li cas. Los ntawm kev qhia tag nrho plaub qhov tsis zoo - thiab ua haujlwm nrog lub chaw tsim khoom teeb pom kev zoo LED uas tshaj tawm cov ntaub ntawv pov thawj photometric - cov neeg yuav khoom zam ob qho kev ua tsis tiav ntawm lub chaw ua haujlwm teeb pom kev zoo: kev teeb tsa uas tsis pom kev, thiab kev teeb tsa ua tsis tiav ntxov.
