LED xim rendering index

Ntau thiab ntau tus neeg nyob rau hauv kev xaiv ntawm lub teeb thiabteeb, lub tswv yim ntawm cov xim rendering Performance index rau hauv cov txheej txheem xaiv.

Raws li lub ntsiab lus ntawm "Tswj Teeb pom kev zoo tsim qauv", xim rendering yog hais txog lub teeb ci piv nrog cov qauv siv teeb pom kev zoo, lub teeb ci nthuav qhia cov yam ntxwv ntawm cov xim ntawm cov khoom.Xim rendering Performance index yog ib qho kev ntsuas ntawm cov xim rendering ntawm lub teeb qhov chaw, qhia raws li cov degree ntawm conformity ntawm cov xim ntawm cov khoom nyob rau hauv lub ntsuas lub teeb qhov chaw thiab cov xim ntawm cov khoom nyob rau hauv lub reference standard light source.

Lub International Commission on Illumination (CIE) tau teeb tsa cov xim rendering Performance index ntawm lub hnub ci ntawm 100, thiab teev 15 xim kuaj, siv R1 ~ R15 los qhia cov zaub Performance index ntawm 15 xim raws li.Yuav kom qhia tau qhov tseeb xim ntawm cov khoom yuav tsum tau siv lub siab xim rendering Performance index (Ra) ntawm lub teeb qhov chaw, nws tus nqi yog ze rau 100, qhov zoo tshaj plaws xim rendering.

General xim rendering Performance index, coj R1 ~ R8 hom qauv xim rendering Performance index ntawm tus nqi nruab nrab, kaw li Ra, characterizing lub teeb qhov chaw xim rendering.Tshwj xeeb xim rendering Performance index xaiv R9 ~ R15 hom qauv xim qauv ntawm cov xim rendering Performance index, kaw li Ri.

Feem ntau peb hais tias cov xim rendering Performance index feem ntau yog hais txog cov xim rendering Performance index, uas yog, tus nqi ntawm Ra, raws li cov "Tsev teeb pom kev zoo tsim qauv," cov kev cai ntawm Ra yam tsawg kawg nkaus ntawm 80, tab sis los ntawm ib tug kev taw qhia ntawm saib, peb kuj xav xav txog qhov tshwj xeeb xim rendering Performance index.

Ntawm lawv, qhov tshwj xeeb xim rendering Performance index R9 yog lub peev xwm los tso saib saturated liab, thaum muasLED teebthiabteebyuav tsum tau them tshwj xeeb rau tus nqi ntawm R9.Qhov siab dua tus nqi ntawm R9, qhov tseeb ntau xim ntawm txiv hmab txiv ntoo, paj, nqaij, thiab lwm yam. Txo.Yog tias lub teeb liab ploj lawm hauv lub teeb, nws yuav cuam tshuam rau qhov zoo ntawm lub teeb pom kev zoo.Yog li tsuas yog thaum Ra thiab R9 muaj nuj nqis siab nyob rau tib lub sijhawm, cov xim rendering siab ntawmLED teebtuaj yeem lav.

Xa mus rau lub teb chaws specification, thaum Ra ≥ 80 thiab R9 ≥ 0 ntawm lub teeb, nws muaj peev xwm ua tau raws li cov xim rendering Performance index xav tau rau kev ua ub no txhua hnub.

Nws yuav tsum tau muab sau tseg tias ntauLED teebntawm kev ua lag luam tam sim no muag nrog qhov tsis zoo R9 qhov tseem ceeb, yog li koj yuav tsum ua tib zoo tshuaj xyuas covteebxaiv.Tsis tas li ntawd, yog tias cov xim rendering Performance index xav tau siab, koj tuaj yeem xaiv Ra ≥ 90, R9 ≥ 70 teeb.

Lub teeb pom kev tsis tshua muaj xim rendering Performance index yuav cuam tshuam rau peb ob lub qhov muag ntawm cov khoom xim pom, ua rau muaj kev poob qis lossis poob qis hauv kev paub xim xim, mus sij hawm ntev hauv cov xim tsis zoo rendering teeb pom kev zoo, tib neeg lub qhov muag lub khob hliav qab ntawm tes yuav raug txo, yooj yim. ua kom pom kev qaug zog, thiab tseem ua rau myopia.

Yog li ntawd, xaiv lub teeb nrog lub siab xim rendering Performance index tuaj yeem tiv thaiv peb lub qhov muag thiab coj peb lub teeb pom kev zoo dua thaum txhim kho cov xim luam ntawm cov khoom.
