Rau cov tub ntxhais kawm, lub teeb yog qhov tseem ceeb rau kev txiav txim siab. Koj tuaj yeem pom tias nws nyuaj rau mloog koj cov kev tshawb fawb yog tias lub teeb pom kev tsis zoo. Txhua yam koj yuav tsum paub txog kev kawm thiab LED lub teeb xim yog them rau hauv kab lus no.
Dab tsi xim LED teeb yog qhov zoo rau kev kawm, ces? Yooj yim hais, ntuj dawb LED lub teeb yog qhov kev xaiv zoo tshaj plaws vim nws feem ntau yuav luag zoo li lub hnub ci ntuj.
Tshawb nrhiav seb qhov zoo tshaj plaws xim kub thiab xim rendering Performance index rau kev kawm yog li cas thiab yuav ua li cas ambient teeb pom kev zoo cuam tshuam rau txoj kev kawm los ntawm kev nyeem ntawv kom paub seb vim li cas lub teeb pom kev zoo yog qhov tseem ceeb rau kev kawm thawj zaug.
Vim li cas thiaj muaj teeb pom kev zoo tseem ceeb rau kev kawm?
Txhawm rau tiv thaiv qhov muag qaug zog, koj xav tau kev teeb pom kev txaus. Nov yog qee qhov taw qhia los pab koj nyob hauv txoj kev:
Xyuas kom tseeb tias lub teeb tsis yog los ntawm ib qho kev taw qhia nkaus xwb. Koj yuav tiv thaiv tau qhov ntxoov ntxoo li ntawd.
Rau kev kawm, xaiv tej yam ntuj tso dawb LED teeb. Cov teeb pom kev zoo no zoo ib yam li nruab hnub nrig (ntxiv rau qhov no hauv ntu tom ntej)
Qhov kub xim twg yog qhov zoo tshaj plaws rau kev kawm?
Nws zoo nkaus li tias lub teeb uas zoo ib yam li nruab hnub nrig yuav tsum yog qhov zoo tshaj plaws rau kev kawm. Nov yog thaum nkag siab xim kub ua qhov tseem ceeb.
Xim kub, uas tau qhia hauv Kelvin (K), yog ib qho tseem ceeb uas yuav tsum tau coj mus rau hauv tus account thaum yuav khoom LED teeb rau kev kawm. Lub teeb qhov chaw xim kub qhia qhov xim ntawm nws lub teeb dawb. Lub teeb txias muaj xim kub, thaum lub teeb sov muaj xim kub.
Cia peb siv ib qho piv txwv los pab peb nkag siab. tswm ciab muaj qhov sov so ci thiab muaj xim kub txog li 1800K. Qhov ci ntsa iab tshaj plaws ntawm lub spectrum yog nruab hnub nrig rau hnub ci ntsa iab. Cov xim kub ntawm xws li lub teeb yog nyob ib ncig ntawm 6500K.
Sov dawb LEDs muaj xim kub ntawm roughly 2700 K, thaum ultra sov dawb LEDs muaj xim kub txog li 2200 K. Sov dawb LEDs yog siv nyob rau hauv teeb pom kev zoo. Whereas, nyob rau hauv cov ntaub ntawv koj tab tom nrhiav rau ntuj dawb LED qhov muag teev (lub teeb ci uas yog qhov ze tshaj plaws rau lub teeb ntuj), xyuas kom tseeb tias cov xim kub tus nqi ntawm cov khoom lag luam yog kwv yees li 4000K.
Yog li, rau kev kawm, peb qhia tias koj xaiv qhov xim kub ntawm kwv yees li 4000K. Hauv qhov tseeb, qhov no txhais tau hais tias koj yuav tsum siv cov teeb pom kev zoo dawb LED rau koj qhov chaw kawm.
Xyuas kom tseeb tias cov xim rendering Performance index (CRI) yog qhov tsim nyog ntxiv rau kom paub tseeb tias cov xim kub tsim nyog rau kev kawm.
Dab tsi yog Qhov Zoo Tshaj Plaws Rendering Index (CRI) rau Kev Kawm?
Yuav pib nrog, cia peb txhais cov xim rendering Performance index yog dab tsi.
Yuav ua li cas yog lub teeb rov tsim cov xim ntawm cov khoom nws illuminates yog txiav txim los ntawm cov xim rendering Performance index (CRI). CRI ntsuas ntawm qhov ntsuas ntawm 0 mus rau 100. Txhua lub teeb uas nyeem 90 lossis siab dua yog hais tias yog qhov zoo. Ntawm qhov tod tes, yog tias kev nyeem ntawv yog 80 lossis qis dua, lub teeb yuav tsis zoo.
CRI90 ntxiv rau LED qhov muag teev muaj qhov zoo ntawm tsis tsim lub teeb xiav (uas tuaj yeem ua rau muaj kev phom sij heev). Cov qij qis qis, ntawm qhov tod tes, tuaj yeem tsim lub teeb xiav thiab yuav tsum zam. Ntxiv mus, CRI90 ntxiv rau LED teeb tsim cov teeb pom kev zoo tshaj plaws uas tsis muaj qhov ci, ua rau lawv zoo tagnrho rau kev kawm.
Peb tsis ntseeg txog kev txi lub teeb zoo, yog li feem ntau ntawm cov qij LED koj yuav pom ntawm peb lub vev xaib muaj CRI ntawm 90 lossis siab dua.
Ambient Teeb pom kev cuam tshuam li cas rau kev kawm?
Cov kws tshawb fawb los ntawm London City University thiab Lund University tau tshawb pom tias thaum lub teeb pom kev zoo siab dua, cov tub ntxhais kawm ua tau zoo dua. Cov tub ntxhais kawm ntawv, uas muaj hnub nyoog 8 txog 9 xyoos, ua tau zoo heev hauv kev sau ntawv, nyeem ntawv, thiab lej hauv chav kawm nrog peb zaug ntawm lub teeb ci ntawm lub qab nthab thiab phab ntsa.
Kev Kawm Tseem Ceeb:
Qhov zoo tshaj plaws LED teeb rau kev kawm yog ntuj dawb vim lawv zoo li ntuj tshav ntuj.
CRI90 ntxiv rau LED qhov muag teev yog qhov kev xaiv zoo tshaj plaws vim lawv tsim cov teeb pom kev zoo tshaj plaws.
Xyuas kom muaj teeb pom kev zoo txaus kom koj tuaj yeem ua tau zoo dua.
