Koj tuaj yeem spec tawm lub teeb pom kev zoo rau lub lumen kawg thiab tseem xaus nrog qhov kev poob siab tom qab kev teeb tsa. Kuv tau pom qhov no tshwm sim: lub tsev so tshiab uas nws sab nrauv zoo li patchy vim qee qhov pheej yig fixtures raug xaiv kom txuag tau nyiaj. Ntawm daim ntawv, cov specs saib zoo - siab wattage, tus IP ntsuam xyuas tawm - tab sis lub installation tsis tuav hauv lub ntiaj teb tiag. Tsis tshua muaj kev ua tsis tiav ib qho. Nws yog cov tshuaj tiv thaiv ntawm cov thermal tsim tsis zoo, tsis zoo optics, tsis ncaj ncees lawm mounting nrug, neeg coob coob, tsis muaj kev tiv thaiv ib puag ncig. Cov ntsiab lus no tau ua ke kom txog thaum lub teeb tsis nyeem cov architecture raws li nws tau npaj.
Qhov no tsis yog kev tsis txaus siab txog kev kawm. Lub tsev sib txawv ntawm cov khoom, nplai thiab raug. Cov huab cua ntsev los ntawm ntug dej hiav txwv rusts sai dua hauv nroog cov pa phem hauv av. Ib tug ntxhib limestone nto yuav hnov mob rau grazing lub teeb sib txawv ntawm txhuam stainless. Phab ntsa ntxhua khaub ncaws tsis yog qhov sib hloov tau. Txoj hauv kev zoo tshaj plaws rau kev teeb pom kev tsis sib haum, cov xim hloov thaum ntxov thiab cov nqi khiav lag luam inflated yog kho lawv li ntawd.
Lub neej ntev yog txiav txim siab los ntawm cov khoom siv thiab kev txiav txim siab thermal
Kev ua tsis tiav thaum ntxov tsis tshua muaj tshwm sim. Nyob rau hauv feem ntau ntawm facade teeb pom kev zoo tej yaam num lawv yog ua ke tshwm sim los ntawm tsis zoo thermal tswj thiab tsis zoo cov khoom xaiv. Cov tuag- nrum cov vaj tse uas tsis tshua muaj nqi yuav ntxeem cua sov hauv qhov chaw kaw thiab ua rau cov chips LED thiab cov tsav tsheb ua haujlwm ntawm qhov kub thiab txias (Tj). Cov teeb meem zoo li lumen depreciation thiab xim hloov nrawm thaum Tj nce thiab feem ntau tsis pom ntawm commissioning, ua pom 6 mus rau 24 lub hlis tom qab kev teeb tsa. Yog li ntawd, nws yog ib qho tseem ceeb uas ob qho tib si cov ntaub ntawv thiab thermal tsim yog hais raws li ib tug system los xyuas kom meej lub sij hawm ntev kev ua tau zoo thiab ruaj khov facade illumination.
1.1) Kev xaiv cov khoom raug yog ib qho tseem ceeb tshaj plaws rau kev ua haujlwm ntev hauv cov phiaj xwm teeb pom kev zoo sab nraum zoov
Hauv kev sib piv hauv teb, cov khoom siv nrog 6063 vaj tse khiav txog 6-12℃txias dua ntawm LED hlws ris piv rau qis dua -qib tuag cast equivalents. Qhov ntsuas kub ntawm qhov sib txuas qis txo qis tus nqi lumen depreciation thiab ncua sijhawm rau L70. Yog tias koj xav txheeb xyuas cov neeg siv khoom thov, nug cov ntaub ntawv LM-80 rau pob LED thiab TM-21 ntxiv rau hauv cov ntaub ntawv sib tw. Cov no yog txoj hauv kev lees paub los ua kom L70 lub neej.
Kev xaiv lub lens yog qhov tseem ceeb sib npaug. Optical- qib PMMA lo ntsiab muag (Ntau dua lossis sib npaug li 90% kev xa tawm) khaws cov kab teeb pom kev zoo thiab txo qhov tawg rau cov pob zeb textured thiab carved nyem. Cov iav tempered tsis tu ncua nyiam ua kom lub teeb tawg ntau dua thiab tsim cov chaw kub. Ntawm kev txuag- qhov siab qhov siab, qhov kho qhov muag yog txhua yam uas xav tau kom paub qhov txawv ntawm cov duab puab uas tau nyeem los ntawm kev ntxuav tsis meej.
1.2) PCB rau Vaj Tsev Thermal Design
Thermal tsim yuav tsum pib ntawm PCB thiab pob qib. Siv hlau- tub ntxhais PCBs (MCPCB) nrog txo thermal txoj kev los ntawm LED nti mus rau lub heatsink. Thermal vias nyob rau hauv lub LED solder pads kom sai hloov tshav kub mus rau hauv lub hauv paus phaj. High conductivity thermal roj los yog thermal pads (TIM) ntawm lub interface ntawm lub LED pob thiab lub tsev kom txo tau qhov kev tiv thaiv tiv thaiv thiab tshem tawm cov huab cua sib txawv uas ua rau kom thermal kuj.
Lub luminaire vaj tse yog ib feem ntawm cov cua sov-dissipation system. Txaus cov hlau loj lossis cov fins yooj yim kom nce qhov chaw. Qhov chaw rau kev txhim kho yog txwv, nyiam conduction rau hauv cov qauv mounting es tsis txhob cua txias ib leeg. Qhov chaw ntawm cov neeg tsav tsheb kuj cuam tshuam rau lub neej ua haujlwm. Tsis txhob kaw cov tsav tsheb hauv cov kab noj hniav yog tias ua tau. Siv cov chaw taws teeb lossis cov tsav tsheb sab nraud lossis tso cov tsav tsheb rau hauv cov qhov cua nkag los tiv thaiv cov neeg tsav tsheb kub los ntawm qhov kub ntawm LED qhov sib txuas.
Xaiv Cov Cuab Yeej Kho Kom Zoo rau Kev Pom Zoo
Tsis yog txhua qhov project xav tau xim, thiab tsis yog txhua qhov xim fixtures tsim cov xim dawb. RGB fixtures tsis muaj ib tug dawb channel feem ntau tawm tsam los ua pastels zoo; RGBW muaj lub siab dawb LED yog li koj tuaj yeem tau txais cov vaj tsev dawb huv thiab cov xim saturated thaum koj xav tau. Rau cov pej xeem plazas lossis kev tshwm sim- tsav facades uas yuav tsum tau muaj ntau yam, RGBW tswj los ntawm DMX512 lossis Art-Net yog txoj hauv kev ntse mus.
Form factor yog huab tais. Linear modules muab rau koj tsis tu ncua, txawm tias ntxuav koj xav tau ntawm cov txuas hniav, podiums lossis qhov siab ntev. Compact nqaim-beam washers yog cov cuab yeej siv rau cornices, qhov rai nthuav tawm lossis cov duab puab. Cia lub architecture txiav txim siab rau tsev neeg fixture, tsis yog lwm txoj kev.
Yuav Ua Li Cas Cov Naj Npawb Stack Up – Ntiaj Teb Tiag Tiag
Kev tiv thaiv qib thiab kev txheeb xyuas cov duab thaij duab yuav tsum yog qhov tseem ceeb hauv kev txiav txim siab thaum txiav txim siab txog kev yuav khoom thiab thuam -cov qauv kev lees paub. IP65 yuav tsum raug suav hais tias yog qhov tsawg kawg nkaus uas yuav tsum tau ua rau sab nrauv facades raug los nag. IP66 raug pom zoo rau qhov chaw nyob hauv ntug dej hiav txwv lossis qhov chaw ntxuav dej yuav tshwm sim. Kev ntsuam xyuas IP yog txhais los ntawm IEC 60529 . Cov haujlwm txhim khu kev qha yuav tsum tsis yog kev tiv thaiv ingress nkaus xwb, tab sis kuj tseem muaj cov ntaub ntawv pov thawj photometric thiab lub neej pov thawj. Nws suav nrog kev thov LM-79 cov ntaub ntawv xeem rau luminaire photometry, thiab LM-80 thiab TM-21 cov ntaub ntawv rau cov pob LED, los txhawb ib qho kev thov ntawm lumen txij nkawm thiab kev pab cuam lub neej.
Xim fidelity yog lwm yam tseem ceeb ntawm architectural facade teeb pom kev zoo. Rau cov teeb pom kev zoo sab hauv, lub hom phiaj CRI ntawm Ntau dua lossis sib npaug rau 80 feem ntau yog txaus. Nyob rau hauv cov ntawv thov uas yuav tsum tau muaj tseeb xim sawv cev ntawm cov ntaub ntawv, qhov yuav tsum tau yuav tsum tau tsa mus rau CRI ntau tshaj los yog sib npaug rau 90. CRI yuav tsum tau augmented nrog IES TM-30 metrics (TM-30-18) kom paub meej ntau yam xim kev ua tau zoo. Cov kev ntsuas zoo li no muab kev nkag siab ntau dua ntawm cov xim zoo nkauj.
Optical and thermal parameters need adjustment for installation geometry and long term maintenance expectations. Choose beam angles based on mounting distance and surface texture Narrow beams (10°-20°) best suited for grazing texture, medium beams (30°-60°) for typical facade washing and very wide beams (>90 degree) rau qhov siab qis qis lossis qhov dav dav. Qhov twg cov luminaires yog offset los ntawm lub façade, asymmetric optics yuav tsum tau teev rau cov teeb pom kev zoo. Thaum kawg, cov ntaub ntawv kev yuav khoom yuav tsum xav tau cov ntaub ntawv pov thawj ntawm kev ua tau zoo thermal thiab ua tau zoo - cov ntsiab lus tau lees paub los xyuas kom meej ntev - lub sij hawm kev ntseeg siab yog kev cog lus tiv thaiv, tsis xav tau.
Kev tiv thaiv corrosion yog cov qauv, tsis yog tshuaj pleev ib ce
Cov neeg siv khoom feem ntau pom txheej txheej ua tiav kov. Nyob rau hauv ib cheeb tsam ntawm ntug dej hiav txwv los yog kev lag luam ib puag ncig, txheej txheej tsis zoo yog qhov pib ua tsis tiav. Housings hmoov coated nrog corrosion tiv thaiv raws li ISO 12944 corrosivity pawg (xaiv C3-C5M raws li tsim nyog). Electrostatic hmoov txheej. A4 Stainless Fasteners & Sealed Cable Glands. Hauv ib qho kev teeb tsa ntawm ntug dej hiav txwv peb tau ua raws li, cov chav tsev coated zoo khaws lub Hoobkas ua tiav tom qab tsib lub caij ntuj no, thaum pheej yig dua cov xim pleev xim rau hauv 18 lub hlis.
Kev Pabcuam thiab Kev Pabcuam - luv luv, cov npe ua haujlwm
Ua ntej yuav tag nrho, ua 2-4 m ntawm -mock site- rau ntawm lub façade tiag tiag los xyuas qhov sib nrug, qaij, nqaj sib tshooj thiab kev tswj lub ntsej muag. Ua qhov kawg kev yuav khoom raws li cov ntaub ntawv ntsuas ntsuas thiab thuam- pom zoo. Ua ib nqe lus luv luv ua haujlwm: Xa LM-79 daim ntawv qhia txog duab thiab LM-80 + TM-21 LED lub neej cov ntaub ntawv nrog kev sib tw kom tso cai rau kev txheeb xyuas tus kheej ntawm kev saib xyuas lumen thiab kev thov rau lub neej. Tsim kom muaj kev nkag mus rau tus neeg tsav tsheb (qhov chaw taws teeb lossis qhov chaw pabcuam sab hauv) thiab yuav tsum tau xa cov khoom siv seem (tsav tsheb, lo ntsiab muag, gaskets) nrog cov txheej txheem hloov pauv thiab lub sijhawm teb.
Khaws ib qho yooj yim tab sis ua tiav kev saib xyuas rau kev saib xyuas tsis tu ncua los sau cov ntaub ntawv ntxuav lub ntsej muag, kev tshuaj xyuas tus neeg tsav tsheb, kho thiab kho kom raug. Pom zoo kom ntxuav txhua txhua 3 lub hlis nyob rau hauv ib puag ncig muaj kuab paug los yog ntug hiav txwv nroog thiab txhua txhua 6 lub hlis nyob rau hauv qhov chaw muaj kuab paug tsawg. Teem sijhawm xim thiab kev kuaj pom duab (lux / tsis sib xws) tom qab commissioning, ntawm 6 lub hlis tom qab ntawd txhua xyoo. Rau RGB / RGBW systems, ib ntus xyuas Δu′v′ tawm tsam cov nplais siv los saib xyuas cov xim hloov. Thaum kawg, cov ntaub ntawv lees paub (lub hom phiaj lux, qhov sib piv sib piv, Tc txwv, tso cai rau lub ntsej muag), thiab xav tau raws li - tsim cov ntawv ceeb toom photometric thiab commissioning cov ntaub ntawv rau qhov kawg kos npe - tawm.
Kev xav zaum kawg
Lub teeb pom kev zoo ntawm lub ntsej muag yog los ntawm kev qhuab qhia kev xaiv: cov ntaub ntawv zoo, lub tswv yim zoo thermal, txoj cai optics rau saum npoo, validated nrog mock-ups thiab LM-79/LM-80 cov ntaub ntawv. Tshem tawm ib qho ntawm cov kauj ruam thiab qhov spec hloov mus rau hauv kev twv txiaj - ib qho uas feem ntau ua rau tsis zoo ib yam, hloov xim thaum ntxov thiab zam tsis tau cov nqi kho. Saib lub luminaire raws li ib qho system (PCB → TIM → vaj tsev → tsav tsheb → tswj ) thiab hais kom cov ntaub ntawv kuaj xyuas qhov tseeb thiab ntawm qhov chaw mock up sign off ua ntej yuav tag nrho.
Thaum koj mus rau qhov kev sib tw lossis koj tab tom tshuaj xyuas cov khoom xa tuaj, tig cov ntsiab lus no rau hauv cov qauv kev lees paub: cov chav kawm IP thiab txheej txheej, LM-79/LM-80/TM-21 deliverables, Tc/thermal test results at ambient ambient, mock-up meter reading and warranty language that covers drivers and ingress seals. Cov kev xav tau no tiv thaiv kev xav tsim nrog rau tus tswv cov peev nyiaj mus sij hawm ntev.
