Puas yog lub teeb LED uas muaj xim siab tseem ceeb?

Thaum xaiv cov teeb LED, ntau tus neeg feem ntau tsom mus rau qhov ci ntsa iab, qhov kub ntawm xim, thiab qhov ntsuas dej tsis nkag, tab sis feem ntau tsis quav ntsej txog qhov tseem ceeb - qhov ntsuas xim (CRI). Ib txhia neeg xav tias "yog tias nws tuaj yeem tso tawm lub teeb thiab ci txaus, nws zoo txaus", thaum lwm tus sib cav seb qhov CRI siab puas yog kev nkim nyiaj. Qhov tseeb, qhov ntsuas xim ncaj qha txiav txim siab "lub peev xwm rov ua dua" ntawm lub teeb. Txawm hais tias nws yog rau kev kho kom zoo nkauj hauv tsev, kev tso saib kev lag luam, lossis cov xwm txheej kev tshaj lij, qhov tseem ceeb ntawmCov teeb ci LED siab CRIntau tshaj qhov xav tau. Tsab xov xwm no yuav teb cov lus nug tseem ceeb "Puas yog CRI siab LED teeb strip tseem ceeb?" los ntawm qhov ntev xws li lub tswv yim, qhov tseem ceeb, kev hloov kho qhov chaw, thiab cov txheej txheem xaiv, pab koj zam kev yuav khoom yuam kev thiab xaiv cov teeb pom kev zoo uas ua tau raws li koj cov kev xav tau hloov kho.

1. Cov xim rendering index (CRI) ntawm cov teeb LED yog dab tsi?
1.1 Lub Ntsiab Lus Txhais ntawm Cov Xim Rendering Index
Xim Rendering Index (CRI), tseem hu ua Xim Rendering Index, yog qhov ntsuas tseem ceeb rau kev ntsuam xyuas lub peev xwm ntawm lub teeb pom kev zoo los sawv cev rau cov xim tiag tiag ntawm cov khoom. Nws ntsuas raws li lub teeb ntuj (nrog CRI ntawm 100 suav tias yog tus qauv siv), thiab tus nqi yog txij li 0 txog 100. Tus nqi ze rau 100, qib siab dua ntawm kev tsim xim los ntawm lub teeb, thiab xim ntawm cov khoom nyob rau hauv lub teeb nyob ze rau lub xeev tiag tiag nyob rau hauv lub teeb ntuj; ntawm qhov tod tes, tus nqi qis dua, qhov xim distortion thiab xim sib txawv ntau dua, thiab cov khoom yuav zoo li tsis ci thiab tsis tob.

1.2 Lub Txhais ntawm High Color Rendering Index (Tus Qauv Kev Lag Luam)
Hauv kev lag luam, feem ntau siv cov ntsuas xim (Ra) los txiav txim siab. Raws li cov xwm txheej ntawm daim ntawv thov, nws muab faib ua peb qib, thiab lawv sib txawv ntawm "xim zoo tib yam" thiab "xim siab":
●- Xim rendering li qub: Ra< 80. Cov xim tsis zoo, thiab muaj qhov sib txawv ntawm cov xim thiab kev cuam tshuam. Nws feem ntau yog siv rau lub teeb pom kev ib ntus uas tsis xav tau cov teebmeem pom (xws li cov tsev rau khoom, txoj kev hauv tsev).
●- Nruab Nrab Mus Rau Siab Xim Rendering: 80 ≤ Ra<90. Qhov kev tsim xim zoo li qub, tsim nyog rau cov kev xav tau teeb pom kev zoo dav dav nrog cov xim tsawg (xws li txoj kev hauv tsev, chav cia khoom);
●Kev ua kom xim zoo: Ra ≥ 90. Kev ua kom xim zoo heev, muaj peev xwm ua kom pom tseeb cov xim qub ntawm cov khoom. Nws yog qhov kev xaiv zoo tshaj plaws rau hauv tsev, chaw ua lag luam thiab chaw ua haujlwm. Ntawm lawv, Ra ≥ 95 yog kev ua kom xim zoo heev, uas tuaj yeem ua tau raws li qhov xav tau siab heev rau kev ua kom xim raug hauv qee qhov xwm txheej.

1.3 Kev nkag siab yuam kev: Xim Rendering Index ≠ Qhov kaj / Kub ntawm xim
Coob leej ntau tus neeg siv feem ntau tsis meej pem txog qhov ntsuas xim nrog qhov ci ntsa iab (lumens) thiab qhov kub xim (K tus nqi). Qhov tseeb, peb yam no yog ywj pheej kiag li thiab tsis cuam tshuam rau ib leeg:
●- Qhov Ci: Qhov no txiav txim seb lub teeb puas "ci txaus". Tus nqi lumen siab dua, lub teeb yuav muaj zog dua.
●- Kub Xim: Txheeb xyuas qhov xwm txheej "txias/sov", xws li 3000K lub teeb sov, 4000K lub teeb nruab nrab, thiab 6000K lub teeb txias;
●- Xim Rendering Index: Qhov no txiav txim siab seb lub teeb pom kev zoo puas "yog" hauv nws lub teeb. Txawm hais tias qib ci ntsa iab lossis qhov kub ntawm xim li cas los xij, Xim Rendering Index siab ua kom cov xim ntawm cov khoom raug tsim tawm raws li qhov tseeb.
Piv txwv yooj yim: Rau tib lub teeb LED sov so 500 lumen, 3000K, ib lub teeb ci ib txwm nrog Ra = 70 yuav ua rau cov khaub ncaws liab zoo li txiv kab ntxwv me ntsis, thaum lub teeb ci xim siab nrog Ra = 95 tuaj yeem ua kom cov xim liab qub ntawm cov khaub ncaws zoo li qub. Qhov no yog lub luag haujlwm tseem ceeb ntawm Color Rendering Index.

II. Cov Lus Teb Tseem Ceeb: Cov teeb LED uas muaj xim zoo heev yog qhov tseem ceeb heev!
Txawm yog siv rau hauv tsev txhua hnub, kev tso saib ua lag luam, lossis kev teeb tsa kev tshaj lij, qhov tseem ceeb ntawm cov teeb LED uas muaj xim siab yog nyob rau hauv peb yam tseem ceeb ntawm "ua kom muaj tiag, txhim kho kev paub, thiab zam kev pheej hmoo". Tshwj xeeb tshaj yog rau cov xwm txheej uas hais txog cov qauv thiab cov teebmeem pom, cov xim siab tsis yog tsuas yog "kev xaiv" tab sis yog "yuav tsum muaj".
