Puas yog LED Teeb Txuag 90% Ntau Lub Zog Tshaj CFLs? Nov yog 5 Qhov Tseeb Koj Yuav Tsum Paub
LED teeb pom kev zoo tau siv dav rau ntau xyoo, tab sis ntau tus neeg yuav khoom tseem muaj lus nug: Dab tsi ua rau lawv zoo dua rau lub zog- txuag teeb (CFLs)? Thiab vim li cas lawv cov nqi sib txawv li ntawd? Niaj hnub no, peb yuav txiav ncaj nraim rau qhov tseem ceeb los pab koj kom paub meej cov ntsiab lus tseeb txog LED teeb pom kev zoo.
1. Kev txuag hluav taws xob tsis yog "90%,"Tab sis 50-80%
Nws feem ntau tau thov nyob rau hauv kev ua lag luam tias "LEDs txuag 90% ntau zog dua li cov qij ib txwm"-tab sis daim duab no siv tshwj xeeb thaum piv rau qhov muag teev. Thaum piv rau lub zog- txuag teeb (CFLs), LEDs feem ntau txuag ntawm 50% thiab 80% ntawm lub zog. Piv txwv li:
- Incab qhov muag teev: 60W → Ib qho kev hloov pauv LED tsuas yog 6-8W (txuag kwv yees . 85%)
- Zog-Txuag Teeb (CFL): 15W → Kev hloov pauv LED tsuas yog 8-10W (txuag kwv yees. 40-50%)
Cov ntsiab lus: LEDs yog lub zog ntau dua -ntau dua li CFLs, tab sis tsis txhob raug dag los ntawm cov lej uas tsis muaj tseeb.
2. 5–10 Lub Sij Hawm Ntev Ntev -Tab sis Them rau Thaum Tshav Kub Dissipation
Theoretical lifespan ntawm ib tug LED tautshaj 50,000 teev;Yog tias siv 10 teev ib hnub, nws tuaj yeem kav ze li 14 xyoo. Txawm li cas los xij, qhov kev ua neej ntev no muaj feem cuam tshuam nrog kev ua kom sov zoo. Tsis zoo- LEDs tsis zoo raug kev txom nyem los ntawm kev tswj cua sov tsis txaus, ua rau qhov kub thiab txias ntawm LED chips nce siab heev, uas tuaj yeem ua rau lawv lub neej luv mus rau ob peb txhiab teev xwb. Thaum yuav khoom, nrhiavaluminium heat sinks thiab LED chips los ntawm cov npe nrov (xws li Lumileds, OSRAM, lossis Epistar).
3. Luminous Efficacy: Saib lm/W, Tsis Wattage
Wattage (W) qhia txog kev siv hluav taws xob, thaum lub teeb ci yog ntsuas hauvlumens (lm).High - LEDs zoo tuaj yeem ua tiav qhov kev ua tau zoo ntawm luminous130-180 lm / W,whereas lub zog-txuag teeb (CFLs) feem ntau nyob ntawm tsuas yog 50–70 lm/W. Piv txwv li:
- Yuav kom ua tiav qhov ci ci ntawm 800 lumens: A CFL xav tau 12-15W, thaum lub LED tsuas yog 5-7W.
- Thaum ua kev yuav khoom, ncaj qha piv cov lumens -ib -watt (lm/W) tus nqi; tus naj npawb siab dua, cov tshuab thev naus laus zis ntau dua.
4. Xim Rendering Index (CRI): 80 Yog "Passable," 90 thiab saum toj no yog "Professional Qib"
Qhov siab dua CRI, qhov tseeb thiab qhov tseeb ntawm cov khoom tshwm sim.
- CRI 80:Txaus rau kev siv sab hauv tsev.
- CRI 85–88:Khw muag khoom, tos txais qhua, chav ua yeeb yam - xa cov xim zoo nkauj dua.
- CRI 90+:Tsev khaws puav pheej, kev yees duab, siab -qhov chaw ua lag luam kawg-kev tshaj lij- qib kev ua haujlwm.
Rau cov khw muag khaub ncaws, kos duab kos duab, thiab cov txee tshuaj pleev ib ce, aCRI ntau dua lossis sib npaug rau 90 ua ke nrog tus nqi R9 (Red Rendering)> 50yog qhov tseem ceeb heev; txwv tsis pub, liab tones yuav tshwm dull lossis greyish.
5. Flicker: Qhov Tsis Pom Kev Noj Qab Haus Huv Hazard
Tsawg-cov teeb pom kev zoo LED feem ntau raug kev txom nyem los ntawm flickering hnyav. Txawm hais tias qhov flicker no tuaj yeem tsis pom qhov muag liab qab, qhov ntev ntev tuaj yeem pomua rau qhov muag strain, mob taub hau, thiab txo concentration.Thaum yuav khoom, insist rau"flicker{0}}free" tsav tsheb,los yog xyuas kom meej tias cov khoom tau dhau IEEE 1789 tus qauv xeem. Txhawm rau tshawb xyuas flicker koj tus kheej, taw tes koj lub koob yees duab smartphone ntawm lub teeb pom kev zoo; Yog tias koj saib cov hlua khi los yog kab txaij ntawm koj lub vijtsam, nws qhia tias flickering loj heev.
Hauv Summary
Thaum muas LED teeb, tsis txhob tsom rau tus nqi nkaus xwb. Nco ntsoov nug txog plaub qhov tshwj xeeb tseem ceeb:Luminous Efficacy (lm/W), Xim Rendering Index (CRI/R9), Flicker -kev ua haujlwm pub dawb, thiab Thermal Management design.Cov plaub yam no txiav txim siab qhov ua tau zoo thiab rov qab los ntawm kev nqis peev ntawm lub teeb pom kev zoo.
Nyob rau hauv kev xav tau ntawm LED teeb pom kev zoo nrog lub siab luminous efficiency, superior xim rendering, thiab flicker - ua haujlwm dawb?
Peb muab cov ntaub ntawv IES thiab 5 xyoo lav. Koj tuaj yeem thov cov qauv rau kev sim.
