Professional Terminology Hais txog LED Teeb

UGR (Unified Glare Rating):Lub International Commission on Illumination (CIE) yog siv los ntsuas cov kev puas siab puas ntsws tsis zoo ntawm cov ntsiab lus teb rau qhov tsis xis nyob los ntawm lub teeb tawm los ntawm cov khoom siv teeb pom kev zoo nyob rau sab hauv tsev pom.

Lumen: Nws yog ib chav tsev ntawm luminous flux. Physics yog txhais raws li ib tug tswm ciab (cd, Candela, chav tsev ntawm luminous siv, sib npaug rau lub luminous siv ntawm ib tug zoo tib yam tswm ciab) ntawm ib lub kaum ntse ntse (ib chav tsev pob nrog ib lub vojvoog ntawm 1 meter, ib lub pob sib xws rau 1 square meter pob. cap) Lub kaum sab xis sawv cev los ntawm lub khob hliav qab sib haum rau tag nrho cov luminous flux generated ntawm lub kaum sab xis ntawm nruab nrab ntu (kwv yees li 65 °). Feem ntau hais lus, Ntau lumens txhais tau tias ntau lub teeb tso zis.

Xim Index:Cov xim rendering peev xwm ntawm lub teeb ci rau ib yam khoom yog hu ua xim rendering, uas yog piv nrog cov tsos ntawm cov khoom nyob rau hauv tib xim kub los yog siv lub teeb qhov chaw (incandescent teeb los yog painting lub teeb). yog 100, tab sis muaj ntau ntau yam ntawm incandescent teeb nyob rau hauv lub neej tiag tiag thiab lawv daim ntawv thov yog txawv, yog li lawv Ra qhov tseem ceeb tsis zoo ib yam nkaus, nws tsuas yog hais tias yuav tsum nyob ze rau 100, uas yog lub teeb nrog cov xim rendering zoo tshaj plaws. .

SMD LED teeb: SMD LED txhais tau tias nto mount lub teeb-emitting diode. Cov no yog cov compact, muaj zog dua, thiab kav ntev tshaj li cov laus tiam ntawm LEDs.Lub teeb ntawm Getled teeb pom kev zoo yuav luag ib txwm muaj qhov tseeb SMD LEDs.
