LED Teeb pom kev zoo: 5 Qhov Tseeb Tseem Ceeb Koj Yuav Tsum Paub
LEDs tsis yog qhov tshiab, tab sis ntau qhov kev xav tsis zoo tseem nyob hauv khw. Cov nram qab no tsib lub ntsiab lus yuav pab koj nkag siab lub ntsiab lus ntawm LED teeb pom kev zoo thiab cov ntsiab lus tseem ceeb los txiav txim siab thaum xaiv.
1. Luminous Efficacy ≠ Brightness; Saib Lumens Per Watt
Cov core metrics rau LEDs yog luminous efficiency (lm/W) -lub teeb emissions ib watt ntawm hluav taws xob noj.
- Standard fluorescent teeb: 50-70lm / W
- Nkag mus-theem LEDs: 80–100 lm/W
- High -Quality LEDs: 130–180 lm/W
Xaus:Rau tib theem ntawm brightness,siab -zoo LEDstxuag tshaj 50% ntawm cov nqi hluav taws xob.
2. Lub neej ntsuas los ntawm L70, Tsis yog "Failure-Kev Ua Haujlwm Dawb"
LEDs tsis dheev hlawv tawm zoo li tsoos filament qhov muag teev; xwb, lawv maj mam dim lub sij hawm. Cov txheej txheem kev lag luam siv L70 metric: tus naj npawb ntawm cov sijhawm ua haujlwm yuav tsum tau ua rau lub teeb pom kev zoo kom degrade mus rau 70% ntawm nws thawj qhov ci ci.
- Tsawg-Quality LEDs: L70 < 10,000 teev
- High-Cov LEDs Zoo: L70 Ntau dua lossis sib npaug li 50,000 teev (Yog tias teeb rau 12 teev hauv ib hnub, lawv tuaj yeem kav ntev dua 11 xyoos.)
3. Xim Rendering Index (CRI) txiav txim siab "Yuav ua li cas zoo saib"
CRI (Ra) ntsuas lub teeb lub peev xwm los tsim cov xim kom raug, nrog rau qhov qhab nia zoo ntawm 100 (xws li lub hnub ci ntuj).
- CRI 80: Haum rau kev lag luam siv dav dav; xim yuav tshwm me ntsis distorted.
- CRI Ntau dua lossis sib npaug li 90: Qhov tseem ceeb rau cov chaw muag khoom, tsev cia puav pheej, thiab chaw kho mob.
- Ua tib zoo saib xyuas tus nqi R9 (liab xim rendering): tus nqi R9> 50 yuav tsum tau txiav txim siab tiag tiag "siab CRI."
4. Thaum tshav kub kub dissipation txiav txim siab ntev
LED chips ua kom sov thaum ua haujlwm; Tsis zoo cua sov dissipation ua rau kom ceev lub teeb degradation, xim hloov, thiab luv luv lifespan.
Yuav ntsuas li cas:
- Yog lub tsev ua los ntawm aluminium alloy(tsis yog yas)?
- Tom qab lub teeb tau qhib rau 30 feeb, kov lub teeb lub cev -Yog hais tias nws hnov kub heev rau kov, nws yuav yog substandard(Qhov kub nce yuav tsum tsawg dua 30 degree).
5. Tus Tsav Tsheb LED yog "Lub Plawv Tsis Pom"
LEDs yog tsawg-voltage DC li; lawv xav tau tus neeg tsav tsheb (lub hwj chim mov) los hloov lub zog AC nkag mus rau hauv qhov tsis tu ncua -DC tam sim no. Tsawg- Cov Tsav Tsheb Zoo: Yooj yim rau flickering, tsis muaj zog txaus, thiab ua tsis tiav ntxov.
High- Cov Tsav Tsheb Zoo:
- PF > 0.9 (High Power Factor)
- Flicker-dawb (Tsis pom muaj banding lossis strobing thaum saib los ntawm lub koob yees duab smartphone)
- Reputable Brands (xws li Meanwell, Philips)
Hauv Summary:
A superior LED fixture combines: High Luminous Efficacy (>130 lm/W) + Ntev Lifespan (L70> 50,000 teev) + High Color Rendering Index (CRI Ntau dua lossis sib npaug rau 90) + Aluminium Alloy Thaum tshav kub kub Dissipation + Tus tsav tsheb tsis tu ncua.
Thaum yuav khoom, tsis txhob tsom mus rau wattage nkaus xwb - txheeb xyuas tsib qhov kev qhia tseem ceeb no kom ntseeg tau tias koj tau txais txiaj ntsig zoo tshaj plaws rau koj cov nyiaj.
Peb muab ntau yam ntawm cov khoom zoo siab - LED teeb pom kev zoo, nrog rau tag nrho cov kev ntsuas tsis tau txhawb nqa los ntawm cov ntawv ceeb toom kuaj tau. Peb txais tos koj los thov cov qauv thiab cov khoom specifications.
