Frankly, tom qab ntau tshaj li kaum xyoo hauv kev lag luam txawv teb chaws, kuv tau pom ntau tus neeg siv khoom tsuas yog tsom rau tus nqi thiab wattage thaum yuav LED txoj kev teeb. Qhov tshwm sim feem ntau yog ib txoj hlua teeb meem tom qab kev teeb tsa. Thaum ib qho chaw ua lag luam lossis chaw ua haujlwm hauv nroog xaiv cov khoom tsis raug, cov nqi tu, kev tsis txaus siab, thiab cov nqi hluav taws xob tag nrho pib nce. Kaum qhov kev txwv no yog qhov koj xav tau tiag tiag kom paub meej ua ntej tso qhov kev txiav txim.
Ua ntej, luminous efficiency (lm / W). Qhov no yog lub hauv paus taw qhia ntawm lub zog efficiency. Tsim nyog LED txoj kev teeb hnub no feem ntau ncav cuag 130 lm / W lossis siab dua; zoo dua ntaus 150 lm / W. Kev ua tau zoo dua txhais tau tias lub zog tsawg dua rau tib lub teeb ci. Tsis txhob yuam kev los ntawm kev ntsuas wattage ib leeg- qee qhov siab -wattage teeb muaj qhov ua tau zoo thiab xaus rau kev siv hluav taws xob ntau dua.
Qhov thib ob, xav txog qhov luminous flux thiab qhov tseeb illuminance. Luminous flux yog tag nrho cov teeb pom kev zoo, tab sis qhov tseem ceeb tshaj yog qhov illuminance thiab uniformity thaum lub teeb tau teeb tsa ntawm txoj kev. Nug tus neeg muag khoom rau photometric curves thiab teeb pom kev zoo simulation kom paub meej tias txoj kev loj thiab kev sib tshuam yuav ua tau raws li cov qauv tsim. Saib ntawm tus naj npawb flux nkaus xwb tuaj yeem coj koj mus rau cov khoom uas nkim ntau lub teeb.
Thib peb, xim kub. Rau cov chaw ua lag luam thiab kev teeb pom kev zoo, nyob ib ncig ntawm 4000K feem ntau yog qhov tsim nyog tshaj plaws. Tsawg dhau thiab lub teeb zoo li yellowish thiab outdated; siab heev thiab nws ua hnyav thiab nkees. Qee qhov haujlwm xaiv 6000K tsuas yog ua kom txoj kev "zoo li ci dua," tsuas yog hnov cov lus tsis txaus siab los ntawm cov neeg tsav tsheb thiab cov neeg ua haujlwm ruaj ntseg txog qhov muag tsis pom kev.
Plaub, xim rendering Performance index (CRI). Rau txoj kev teeb pom kev zoo, Ra70 lossis siab dua yog pom zoo; thaj chaw uas xav tau cov khoom zoo dua yog qhov zoo dua ntawm Ra80. CRI siab dua ua rau cov cim kev, xim tsheb, thiab cov teeb meem pom tseeb, uas ncaj qha txhim kho hmo ntuj - sijhawm nyab xeeb.
Thib tsib, IP ntsuam xyuas. Sab nraum zoov teeb yuav tsum yog yam tsawg kawg nkaus IP65; Hauv cov chaw ua haujlwm plua plav lossis nag los nag, IP66 yog qhov zoo dua. Kev tiv thaiv tsis txaus cia dej thiab plua plav hauv, thiab lub neej ntev ntawm cov khoom siv poob qis heev.
Thib rau, IK cuam tshuam kev ntsuas ntsuas. Cov teeb pom kev zoo raug teeb tsa raws txoj kev thiab tuaj yeem raug pob zeb, ceg ntoo, lossis kev sib tsoo lub teeb. IK08 lossis siab dua yog qhov kev xaiv zoo dua, tshwj xeeb tshaj yog nyob rau hauv qis ncej lossis ze rau thaj chaw ua haujlwm.
Xya, tsav tsheb zoo. Tus tsav tsheb yog lub plawv ntawm LED txoj kev teeb. Txheeb xyuas qhov input voltage ntau, lub zog muaj zog (xws li 0.95 lossis siab dua), thiab qib tiv thaiv surge. Qhov hluav taws xob hauv cov chaw ua si tuaj yeem tsis ruaj khov; tus neeg tsav tsheb tsis zoo feem ntau ua rau kev ua tsis tiav.
Yim, cua sov dissipation tsim thiab cov ntaub ntawv. Cov teeb pom kev zoo siv kev sib xyaw ua ke ntawm aluminium alloy cua sov dab dej nrog cov thermal tsis tshua muaj zog, uas ua rau lub lumen depreciation qeeb. Kev tswj xyuas hluav taws xob tsis zoo ua rau LED nti kub thiab txo qis kev ua neej thiab kev ua tau zoo. Ib qho khoom vaj khoom tsev sib npaug, feem ntau txhim khu kev qha.
Cuaj, lifespan thiab lumen tu cov ntaub ntawv. Tsis txhob cia li lees txais "50,000 teev" lossis "100,000 teev." Nug rau LM80 cov ntawv xeem thiab TM21 qhov kev kwv yees. Cov khoom lag luam ntseeg tau tuaj yeem khaws lumen depreciation nyob rau hauv ib qho kev pom zoo tom qab tsib mus rau yim xyoo ntawm kev siv ib txwm.
Kaum, ntse tswj compatibility. Ntau qhov haujlwm tam sim no xav tau kev dimming, kev txav chaw, lossis kev saib xyuas tej thaj chaw deb. Paub meej tias cov khoom siv txhawb nqa 0-10V, DALI, lossis wireless raws tu qauv thiab seb lawv tuaj yeem txuas tau zoo rau cov tshuab ntse uas twb muaj lawm lossis tshiab. Yog tias lawv tsis ua, kev hloov kho yav tom ntej yuav nyuaj.
Ntawm cov kaum qhov tsis zoo no, kev ua tau zoo, kev tsav tsheb zoo, kev ntsuas kev tiv thaiv, thiab kev ua kom sov yog qhov tseem ceeb tshaj plaws. Tsawg- cov khoom lag luam pheej yig feem ntau txiav cov ces kaum ntawm cov ntsiab lus no. Peb cov neeg ua lag luam txawv teb chaws paub tias cov neeg siv khoom ntshai loj - qhov ua tsis tiav hauv ib xyoos lossis kev txuag hluav taws xob uas tsis muaj txiaj ntsig.
Thaum yuav khoom, tig kaum cov khoom no mus rau hauv ib daim ntawv teev npe thiab nug tus neeg muag khoom kom muab cov ntaub ntawv thiab cov ntawv ceeb toom rau txhua tus. Nws yog qhov ntseeg tau ntau dua li qhov yooj yim piv cov nqi. Sau cov ntsiab lus tseem ceeb thiab cov ntsiab lus lav kom meej hauv daim ntawv cog lus kom tsis txhob muaj teeb meem tom qab.
Yog koj yogmuab cov LED txoj kev teebrau ib qho chaw ua lag luam lossis ib qhov project txawv teb chaws thiab xav tau kev pab soj ntsuam cov khoom tawm tsam cov kev txwv no -lossis xav pom lawv ua haujlwm li cas hauv cov haujlwm tiag tiag-cia li sib cuag. Kuv tuaj yeem qhia qhov kev xaiv ua tau zoo thiab cov kev tsis zoo uas yuav zam tau. Tau qhov tsis raug, thiab qhov project nyob twj ywm rau hauv av.
