LED Teeb pom kev zoo: Txhua tus neeg yuav khoom yuav tsum paub hauv 5 feeb
LED technology tau matured. Tab sis ntau tus neeg yuav khoom tseem txiav txim siab teeb los ntawm wattage ib leeg. Qhov ntawd zoo li yuav lub tsheb los ntawm saib tsuas yog cov roj tank loj. Nov yog qhov tseem ceeb.
1. Lumens, Tsis Watts
- Watts =siv zog
- Lumens =lub teeb tso zis
A 10W LED can easily replace a 40W fluorescent tube. Always compare lumens per watt (lm/W). Good LEDs: 130–180 lm/W. Excellent: >200 lm/w.
2. Lifespan: L70 yog tus lej tiag
Cov neeg tsim khoom thov "50,000 teev." Tab sis qhov ntawd txhais li cas?
Nrhiav L70 - teev kom txog thaum lub teeb tso zis poob rau 70% ntawm thawj zaug.
- Pheej yig LEDs: L70 ntawm 15,000-25,000 teev
- LEDs zoo: L70 ntawm 50, 000+ teev
Hauv cov ntsiab lus tiag: 12 teev / hnub ua haujlwm → 50,000 teev=11+ xyoo.
3. CRI (Color Rendering Index) – Lub Tuam Txhab Muag Khoom Muag
- CRI 80:standard, zoo rau warehouses
- CRI 85–88:zoo rau chaw ua haujlwm, tsev kawm ntawv
- CRI 90+:qhov tseem ceeb rau khw muag khoom, chaw ua yeeb yam, tsev so
- High CRI ua rau cov khoom zoo dua. Rau lub khw muag khaub ncaws, kev kho dua tshiab los ntawm CRI 80 mus rau CRI 90 tuaj yeem nce kev hloov pauv ncaj qha.
Tsis txhob hnov qab R9(liab rendering). Ntau 80 CRI teeb muaj R9 < 10 - liab zoo li xim av. Zoo siab -CRI teeb muaj R9> 50.
4. Flicker – Tus neeg tsis txaus siab uas ntsiag to
Flicker ua rau qhov muag mob, mob taub hau, thiab txawm qaug dab peg hauv cov tib neeg rhiab heev.
- Cov tsav tsheb tsis zoo: flicker index> 0.1
- Cov tsav tsheb zoo: flicker index <0.02, IEEE 1789 ua raws
Kuaj nrog lub koob yees duab smartphone - yog tias koj pom cov hlua khi, nws yog flickering.
5. Kub=yeeb ncuab
LEDs tsim hluav taws xob tsawg dua li qub thev naus laus zis, tab sis cua sov tseem tua lawv.
- Kev sib tshuam kub> 85℃→ lifespan plummets
- Cov teeb pom kev zoo siv cov tuab aluminium vaj tse thiab cov txheej txheem thermal kom zoo
Lub teeb yuag yas LED yuav zoo li txias, tab sis qhov ntawd txhais tau hais tias cua sov yog nyob rau hauv - thaum ntxov tsis ua hauj lwm lav.
6. Cov ntaub ntawv pov thawj
Yam tsawg kawg nkaus: CE, RoHS. Rau North America: UL lossis ETL. Rau sab nraum zoov: IP65 lossis siab dua.
Nug cov ntawv xeem (IES LM-79, LM-80). Yog tias tus neeg muag khoom tsis tuaj yeem muab rau lawv, taug kev mus.
Daim ntawv teev npe ceev ua ntej yuav
| Feature | Yuav nrhiav dab tsi |
|---|---|
| Kev ua tau zoo | Ntau tshaj lossis sib npaug li 130 lm / W |
| L70 | Ntau dua lossis sib npaug li 50,000 teev |
| CRI | Ntau dua lossis sib npaug rau 80 (Ntau dua lossis sib npaug rau 90 rau kev muag khoom / tsev kho mob) |
| R9 | Ntau dua lossis sib npaug rau 50 rau siab CRI |
| Flicker | Ua raws li IEEE 1789 |
| Warranty | Ntau dua lossis sib npaug li 5 xyoos |
| Tshaj tawm | IES LM-79 muaj |
Kab hauv qab
LEDs yog cov khoom lag luam - tab sis tsis yog txhua qhov sib npaug. Them 20% ntau dua rau qhov zoo tiag tiag txuag koj 100% ntawm kev mob taub hau (thiab cov nqi hloov pauv) tom qab.
Xaiv qhov ua tau zoo, xim zoo, thiab thermal tsim. Koj ob lub qhov muag - thiab koj daim nqi hluav taws xob - yuav ua tsaug rau koj.
