Thaum xaiv qhov muag - tiv thaiv LED teeb, koj yuav tsum tsom mus rau cov cim tseem ceeb xws li lub teeb pom kev zoo, kev tswj flicker, teeb xiav teeb pom kev zoo, xim rendering thiab lub teeb xis nyob. Hauv qab no yog daim ntawv qhia kev yuav khoom:
I. Cov qauv tseem ceeb ntawm qhov muag - tiv thaiv LED teeb
1. Tsis muaj flicker (Qhov tseem ceeb Factor !)
Hazard: Flicker tuaj yeem ua rau pom kev qaug zog thiab mob taub hau, tshwj xeeb tshaj yog rau cov menyuam yaus thiab cov neeg rhiab heev.
Kev kuaj xyuas txoj kev:
Taw tes lub koob yees duab lub xov tooj ntawm lub teeb, thiab yog tias muaj ripples ntawm qhov screen, muaj flicker.
Choose products marked "no visible flicker" or "high-frequency dimming (>3125 Hz).
Cov cuab yeej siv tau pom zoo: DC fais fab mov (DC) lossis siab - cov khoom siv hluav taws xob tsis tu ncua tam sim no.
2. Tsawg xiav teeb phom sij (RG0 qib)
Hazard: luv-yoj xiav lub teeb (400-450nm) yuav ua rau lub retina puas.
Ntawv pov thawj standard:
RG0 (tsis muaj teeb meem xiav xiav) lossis RG1 (tsawg txaus ntshai) hauv IEC 62471 ntawv pov thawj.
Xaiv lub teeb sov sov nrog cov xim kub tsawg dua lossis sib npaug li 4000K (tsawg feem ntawm lub teeb xiav).
3. High colour rendering Performance index (CRI Ntau dua lossis sib npaug rau 95)
Muaj nuj nqi: rov kho qhov tseeb xim ntawm cov khoom thiab txo lub nra ntawm lub qhov muag hloov mus rau xim sib txawv.
Txheem:
Ordinary LEDs muaj CRI ntau dua los yog sib npaug rau 80, thiab qhov muag tiv thaiv teeb yuav tsum tau aCRI ntau dua lossis sib npaug rau 95(xws li Ra95).
Cov kev xav tau tshwj xeeb (xws li pleev xim) tuaj yeem xaivR9＞90(liab xim rendering index).
4. Kho xim kub (2700K ~ 5000K)
Pom zoo scenarios:
Kev nyeem ntawv / kawm: 4000K lub teeb nruab nrab (sib npaug concentration thiab kev nplij siab).
Hmo ntuj so: 2700K ~ 3000K sov lub teeb daj (txo melatonin suppression).
5. Illumination uniformity (AA lossis A qib)
Lub teb chaws tus qauv (GB/T 9473-2017):
Qib AA: illumination Ntau dua lossis sib npaug rau 500lx, uniformity Tsawg dua lossis sib npaug rau 3.
Qib A: Lub teeb pom kev zoo dua lossis sib npaug ntawm 300lx, uniformity Tsawg dua lossis sib npaug rau 3.
