Dab tsi wattage ntawm LED Stadium Teeb pom kev zoopuas tsim nyog?
Taw qhia
Lub evolution ntawm cov chaw ua si illumination tau profoundly zoo li tus LED (Light Emitting Diode) technology. Niaj hnubLED chaw ntau pob teebsawv cev rau kev hloov pauv, muab kev ua haujlwm zoo dua qub, kev tswj kho qhov muag, kev ua haujlwm ntev, thiab kev tsim qauv yooj yim piv rau cov teeb pom kev zoo xws li hlau halide. Tsab ntawv xov xwm no muab cov kev qhia tob tob rau hauv cov ntsiab lus tseem ceeb engineering, kev ntsuas kev ua tau zoo, thiab cov qauv tsim tshiab uas txhais cov tiam tam sim no ntawm siab -kev ua tau zooLED chaw ntau pob teeb pom kev zoo cov kev daws teeb meem, kos cov kev pom los ntawm kev nce qib patented tsis ntev los no. Ua raws li EEAT (Kev Paub, Kev Txawj Ntse, Kev Tso Cai, Trustworthiness), qhov kev tshuaj ntsuam no suav nrog cov ntaub ntawv siv tswv yim engineering, kev siv rau cov qauv kev lag luam, thiab cov pov thawj-raws li kev ntsuam xyuas ntawm cov thev naus laus zis tseem ceeb xws li thermal tswj systems, glare tswj optics, thiab modular installation architectures.
Dab tsi yog Cov Txheej Txheem Kev Tswj Xyuas Thermal Advanced nyob rau niaj hnub LED chaw ntau pob teeb?
Kev siv hluav taws xob zoo yog qhov tseem ceeb tshaj plaws uas txiav txim siab qhov kev ua tau zoo, kev ua haujlwm zoo, thiab lub neej ntevLED chaw ntau pob teeb. Kev sib tshuam kub ntau dhau ua rau lub lumen depreciation thiab tuaj yeem ua rau muaj kev puas tsuaj loj. Cov qauv tsim niaj hnub tau txav mus dhau qhov yooj yim extruded aluminium heatsinks kom sib xyaw ua ke, ntau yam -faceted thermal txoj kev.
Tsis ntev los no patents, xws li CN 221483554 U thiab CN 223049977 U, qhia txog ob lub tswv yim tseem ceeb. Thawj tus neeg ua haujlwm antshiab aluminium welded heatsink. Txoj kev no tsim cov qauv monolithic nrog cov thermal conductivity siab (kwv yees . 229 W/m·K), qhov hnyav, thiab optimized fin geometry rau kev txhim kho natural convection. Lub tswv yim thib ob, ua piv txwv hauv patent CN 223049977 U, yogkev sib cais ntawm lub cev ntawm cov khoom cua sov. Los ntawm kev cais lub siab -kub LED module los ntawm chav tsev fais fab mov, txhua yam tuaj yeem ua kom txias dua, tiv thaiv thermal saturation thiab ua kom yooj yim txij nkawm.
Ib txoj hauv kev zoo tshaj plaws yog nthuav dav hauv patent CN 117810351 A, uas qhia txogdirect-txuas, (thermally & electronicly cais) architecture. Qhov kev tsim no tshem tawm cov tsoos insulating txheej thiab thermal interface cov ntaub ntawv zoo li roj. Xwb, LED nti lub thermal ncoo yog ncaj qha soldered los ntawm ib tug ntawm ib tug saj zawg zog Circuit Court board mus rau lub heatsink los yog ib tug tshwj xeeb thermal choj (xws li, ib tug tooj liab plug los yog ib tug plated txheej). Qhov no ua rau luv luv txoj kev thermal, txo cov thermal kuj, thiab txo qhov kev pheej hmoo ntawm TIM degradation dhau sijhawm.

Yuav Ua Li Cas Optical Systems Ua Tau Zoo Tshaj Plaws -Qib Illumination thiab Glare Control?
Optical design ntawm ibLED chaw ntau pob teebyuav tsum ua kom tau raws li cov qauv kev ua haujlwm nruj rau kab rov tav thiab ntsug illuminance, uniformity, thiab, tseem ceeb heev, glare tswj. Kev tswj tsis tau lub ntsej muag ( ntsuas raws li Kev Sib Koom Siab Glare Rating - UGR) cuam tshuam kev ua kis las ncaws pob thiab cov neeg saib.
Advanced systems siv cov txheej txheem kho qhov muag. Raws li pom nyob rau hauv patent CN 221483554 U, ib txwm high -end module integrates athawj silicone lensrau precise beam shaping, aSecondary reflector(feem ntau yog PC lub tshuab nqus tsev aluminium-coated reflector khob) txhawm rau txhim kho lub teeb thiab kev ua haujlwm, thiab thaum kawg,tshwj xeeb glare ntaub thaiv npog los yog visor. Qhov no multi-theem tswj tso cai rau kev txiav ntse-tawm cov ces kaum, txo lub teeb ci thiab coj teeb pom kev ncaj qha mus rau qhov chaw ua si.
Tsis tas li ntawd, niaj hnub fixtures yog tsim raumodularity thiab adaptability. Tib lub tshuab kho qhov muag tuaj yeem haum nrog qhov sib txawv nruab nrab optics lossis cov ntaub thaiv npog kom ua tau raws li qhov yuav tsum tau muaj ntawm ntau yam kev ua kis las- los ntawm qhov dav, cov kev pabcuam zoo ib yam xav tau rau kev ncaws pob mus rau qhov tshwj xeeb ntsug illuminance xav tau rau kev tshaj tawm hauv TV hauv kev ntaus pob tesniv lossis ntaus pob.

Dab tsi yog qhov tseem ceeb rau kev teeb tsa, kav ntev, thiab ntse nta?
Kev ua haujlwm ntawmsiab -kev ua tau zoo LED chaw ntau pob teeb pom kev zoo fixturestsuas yog paub los ntawm kev txhim kho ruaj khov thiab ntev - lub sij hawm durability. Patents qhia txog kev tsom mus rauntau yam mounting systems. Cov qauv tsim feem ntau muaj ob txoj kev xaiv: aU-shaped adjustable bracketrau ruaj ncej mounting nrog 360℃kab rov tav thiab meej ntsug hloov, thiab ib tugrotating puag (yoke)rau phab ntsa los yog kaum mounting. Qhov kev hloov pauv no ua kom ntseeg tau tias tib lub luminaire tuaj yeem xa mus rau hauv ntau qhov chaw, los ntawm cov ncej nyob ib leeg mus rau cov kab pheeb suab- mounted installation nyob rau hauv tsev arenas.
Durability yog hais los ntawmKev tiv thaiv ingress (IP65 lossis siab dua)tiv taus plua plav thiab dej dav hlau,corrosion-cov ntaub ntawv tiv taus(piv txwv li, hmoov-coated aluminium, stainless hlau hardware), thiabrobust thermal tsimuas ua kom ruaj khov ua haujlwm thoob plaws qhov kub thiab txias (-40℃rau +50℃yog qhov ntau). Kev sib cais ntawm covtsav tsheb (power supply)los ntawm LED module, raws li tau hais tseg hauv ntau daim ntawv pov thawj, tsis yog tsuas yog pab ua kom txias xwb tab sis kuj ua kom yooj yim txij nkawm- tus tsav tsheb ua tsis tau zoo tuaj yeem hloov pauv yam tsis tau rhuav tshem tag nrho cov khoom siv kho qhov muag.
Lub neej yav tom ntej nyob hauvtxuas thiab ntse systems. Niaj hnubLED chaw ntau pob teeb systems yog nceDALI (Digital Addressable Lighting Interface)los yogwirelessly enabled, tso cai rau kev tswj hwm hauv nruab nrab, dimming, teem sijhawm, thiab cov teeb pom kev zoo dynamic (xws li kev sib koom ua keRGBW xim sib xyawrau cov xwm txheej lom zem raws li tau sau tseg hauv CN 221483554 U). Embedded sensors tuaj yeem muab cov ntaub ntawv ntawm kev siv hluav taws xob, sijhawm ua haujlwm, thiab txawm tias tiag tiag - lub sijhawm saib xyuas kev noj qab haus huv, ua kom muaj kev saib xyuas zoo.
Kev Lag Luam Kev Sib Tw thiab cov kev daws teeb meem
Kev Sib Tw 1: Kev nqis peev siab pib thiab ua kom pom tseeb ROI.
Kev daws:Ua ib daim ntawv qhia ntxaws txog Kev Ntsuas Tus Nqi Them Lub Neej (LCCA). Thaum tus nqi upfront ntawm kev tshaj lijLED chaw ntau pob teeb pom kev zoo fixturesyog siab dua, ROI tau paub los ntawm kev txuag hluav taws xob (feem ntau 50-70%), txo kev txij nkawm (ntev lub neej ntev, kho modular), thiab qis qis qis hauv cov chaw sab hauv tsev. Kev them nyiaj rov qab siv hluav taws xob thiab tsoomfwv kev txhawb siab rau kev hloov kho hluav taws xob tuaj yeem txhim kho kev muaj peev xwm nyiaj txiag ntxiv.
Kev Sib Tw 2: Lub Rooj Sib Tham Sib Tham Sib Tham thiab Txhim Kho Kev Ua Si Ncaws Pob Ntaus Pob.
Kev daws:Koom nrog cov tsim teeb pom kev zoo thiab cov chaw tsim khoom thaum ntxov hauv qhov project. Qhia fixtures nrogadjustable optics thiab meej aiming peev xwm. Xyuas kom tseeb tias cov qauv tsim tau raug lees paub los ntawm kev simulation software (xws li Dialux, Relux) tiv thaiv cov qauv tsim (FIFA, IES RP-6, EN 12193) ua ntej kev teeb tsa.
Kev Sib Tw 3: Ua kom ruaj khov ntev -Lub Sijhawm Ua Haujlwm thiab Xim Zoo ib yam.
Kev daws:Xaiv cov khoom siv los ntawm cov tuam txhab muaj npe nrov uas muab cov ncauj lus kom ntxawsLM-80 (LED lumen kho)thiabTM-21 (kwv yees lub neej)qhia. Saib rau kev lees paub uas tsis yog tsuas yog cov khoom siv xwb tab sis kuj lav qhov tsawg kawg nkaus lumen tso zis (piv txwv li, L70> 100,000 teev) thiab xim hloov siab ntev ntev. Kev tsim thermal tsim nyog, raws li tau hais tseg, yog qhov tseem ceeb los ua kom tau raws li cov kev lees paub no.
