Lub teeb ci LED muaj xws li:
Brightness L: lub luminous flux ntawm lub cev luminous nyob rau hauv ib qho kev taw qhia, chav tsev lub kaum ntse ntse, chav tsev.Unit: Nit(cd/㎡).
Luminous flux φ: tag nrho lub teeb emitted los ntawm lub cev luminous ib ob.Chav tsev: Lumens (Lm), uas qhia tias lub teeb ntau npaum li cas cov khoom luminous emits.Lub teeb ntau dua qhov teeb pom kev zoo, qhov ntau dua ntawm lumens.
Tom qab ntawd: qhov ntau dua cov lumens, qhov ntau dua qhov luminous flux, thiab qhov ci ntawm lub teeb ntau dua.
2. wavelength
LEDs nrog tib lub wavelength muaj tib xim.Nws yog ib qho nyuaj rau cov tuam txhab uas tsis muaj LED spectrophotometers los tsim cov khoom nrog cov xim ntshiab.
3. Xim kub
Xim kub yog ib chav ntsuas ntsuas uas txheeb xyuas cov xim ntawm lub teeb, qhia hauv K tus nqi.Lub teeb daj yog "qis dua 3300k", lub teeb dawb yog "siab dua 5300k", thiab muaj xim nruab nrab "3300k-5300k".
Cov neeg siv khoom tuaj yeem xaiv lub teeb pom kev zoo nrog cov xim kub uas tsim nyog raws li lawv tus kheej nyiam, kev thov ib puag ncig, thiab cov teeb pom kev zoo thiab qhov chaw uas lawv xav tau los tsim.
