2024-09-13 14:33:34 dr hab
Xim rendering Performance index (CRI) yog ib qho kev siv feem ntau hauv kev siv tshuab teeb pom kev zoo. Nws yog hais txog qhov ntsuas ntawm qhov degree uas cov xim ntawm ib yam khoom zoo ib yam thaum nws yog illuminated los ntawm lub teeb qhov chaw no thiab thaum nws yog illuminated los ntawm ib tug standard lub teeb qhov chaw (feem ntau siv hnub ci raws li tus qauv teeb qhov chaw), uas yog, li cas. tiag tiag cov xim yog.
1.CRI txhais
Rau cov kws kho teeb pom kev zoo, xim rendering Performance index (CRI) yog ib lo lus siv ntau. Peb feem ntau pom tus nqi CRI hauv cov ntaub ntawv ntawm lub teeb ci, thiab paub tias nws cuam tshuam qhov zoo ntawm lub teeb pom kev zoo ntawm cov xim rendering.
Tab sis nws txhais li cas tiag? Tus nqi CRI pab txiav txim siab seb lub teeb yuav tsum siv li cas hauv lub teeb pom kev zoo. Qhov siab dua tus nqi CRI, qhov zoo dua, tab sis tib neeg puas paub qhov nws ntsuas qhov tseeb thiab ntsuas nws li cas? Piv txwv li, tus nqi CRI ntawm OLIGHT S1MINI yog 90. Cov ntaub ntawv no qhia dab tsi? Lub teeb pom kev zoo ntawm lub tsev cia puav pheej yuav tsum siab tshaj CRI 95. Vim li cas?
Txhawm rau muab nws yooj yim: xim rendering yog ib qho tseem ceeb rau kev ntsuam xyuas lub teeb pom kev zoo, thiab xim rendering Performance index yog ib qho tseem ceeb rau kev ntsuam xyuas cov xim rendering ntawm lub teeb. Nws yog ib qho tseem ceeb rau kev ntsuas cov yam ntxwv xim ntawm cov khoom siv hluav taws xob. Qhov siab dua qhov xim rendering Performance index, qhov zoo dua qhov xim rendering ntawm lub teeb ci. Qhov zoo ntawm cov xim, qhov muaj zog ntawm cov xim rov qab muaj peev xwm ntawm cov khoom.
Lub International Commission on Illumination (CIE) txhais cov xim rendering xws li: cov nyhuv ntawm lub teeb ci ntawm cov xim ntawm cov khoom piv nrog cov qauv siv lub teeb ci.
Hauv lwm lo lus, CRI yog ib qho kev ntsuas ntawm cov xim pom ntawm lub teeb ci piv nrog cov qauv teeb pom kev zoo (xws li lub teeb nruab hnub). CRI yog ib qho kev ntsuas thoob ntiaj teb lees paub thiab tib txoj hauv kev los ntsuas thiab tshaj tawm cov xim rendering ntawm lub teeb ci. txoj kev.
Kev tsim cov qauv CRI metric tsis nyob deb. Lub hom phiaj tseem ceeb ntawm kev tsim cov qauv no yog siv los piav qhia cov xim rendering cov khoom ntawm cov teeb fluorescent uas tau siv dav hauv xyoo 1960s, thiab pab cov neeg siv nkag siab tias cov teeb fluorescent nrog linear spectral faib tuaj yeem siv rau lub sijhawm twg.
2.CRI technology
Txawm hais tias cov xim swatches no tau ua tib zoo teev thiab cov khoom tiag tuaj yeem tsim cov xim ntawm cov swatches no, nws yog ib qho tseem ceeb kom nkag siab tias CRI qhov tseem ceeb tau muab los ntawm kev suav tag nrho thiab tsis tas yuav teeb lub teeb xim tiag tiag nrog lub teeb tiag tiag.
Qhov peb yuav tsum tau ua yog siv qhov ntsuas lub teeb pom kev zoo los sib piv nrog cov spectrum ntawm cov qauv xim uas tau teev tseg, thiab tom qab ntawd muab thiab xam cov nqi CRI los ntawm kev txheeb xyuas lej.
Yog li, qhov ntsuas ntawm CRI tus nqi yog qhov ntau thiab lub hom phiaj. Nws tsis yog ib qho kev ntsuas kev ntsuas (kev ntsuas qhov ntsuas tsuas yog nyob ntawm tus neeg soj ntsuam uas tau kawm los txiav txim seb qhov twg lub teeb muaj xim zoo dua).
Kev sib piv raws li kev pom xim kuj tseem muaj txiaj ntsig, yog tias cov xim kub ntawm ob qho tib si ntsuas lub teeb thiab qhov siv lub teeb ci yuav tsum yog tib yam.
Piv txwv li, sim los sib piv cov tsos ntawm ob zoo tib yam xim swatches illuminated los ntawm ib tug sov dawb lub teeb qhov chaw nrog ib tug xim kub ntawm 2900K thiab ib tug txias dawb lub teeb qhov chaw (hnub ci) nrog ib tug xim kub ntawm 5600K yog ib tug tag nrho nkim sij hawm.
Lawv yuav tsum saib txawv, yog li qhov sib txheeb xim kub (CCT) ntawm qhov ntsuas lub teeb yog xam los ntawm spectrum ntawm lub teeb ci. Thaum koj muaj qhov xim kub no, lwm qhov siv lub teeb ci ntawm tib xim kub tuaj yeem tsim ua lej.
Rau qhov ntsuas lub teeb pom kev zoo nrog cov xim kub qis dua 5000K, qhov siv lub teeb pom kev yog lub cev dub (Planck) radiator, thiab rau qhov ntsuas lub teeb nrog xim kub siab tshaj 5000K, qhov siv lub teeb ci yog CIE tus qauv illuminant D.
Kev xaiv tuaj yeem muab cov spectrum ntawm qhov siv lub teeb pom kev zoo nrog txhua tus qauv xim los tsim cov txheej txheem ntawm cov ntsiab lus siv xim zoo tagnrho (cov ntsiab lus xim luv).
Tib yam muaj tseeb rau lub teeb qhov chaw nyob rau hauv kev sim. Lub spectrum ntawm lub teeb ci nyob rau hauv kev sim yog ua ke nrog txhua tus qauv xim kom tau txais lwm cov ntsiab lus xim. Yog tias cov xim taw tes nyob rau hauv qhov ntsuas qhov teeb pom kev zoo sib haum rau cov xim taw tes hauv qab qhov siv lub teeb pom kev zoo, peb xav txog lawv cov xim rendering zog kom zoo ib yam thiab teem lawv tus nqi CRI rau 100.
Nyob rau hauv daim ntawv qhia xim, qhov deb ntawm cov xim taw tes nyob rau hauv qhov ntsuas lub teeb yog los ntawm qhov zoo tagnrho txoj hauj lwm, cov xim rendering zuj zus thiab qis dua tus nqi CRI.
Xam cov xim hloov ntawm 8 khub ntawm cov qauv xim sib cais, thiab tom qab ntawd suav 8 qhov tshwj xeeb xim rendering indexes (CRI tus nqi ntawm lub teeb ci rau qee yam xim qauv hu ua qhov tshwj xeeb xim rendering Performance index), thiab tom qab ntawd coj lawv cov lej lej, yog li tus nqi tau txais yog CRI tus nqi.
Tus nqi CRI ntawm 100 txhais tau hais tias tsis muaj xim sib txawv ntawm ib khub ntawm cov qauv xim hauv yim khub ntawm cov qauv xim hauv qab qhov ntsuas lub teeb thiab qhov siv lub teeb ci.
3.Dab tsi yog qhov xim rendering Performance index ntawm LED teeb nyob ntawm?
Cov xim rendering Performance index ntawm LED teeb tsuas yog nyob ntawm qhov zoo thiab qhov sib piv ntawm phosphorus. Qhov zoo thiab qhov sib piv ntawm phosphors muaj qhov cuam tshuam tseem ceeb ntawm cov xim rendering Performance index ntawm LED teeb. Cov phosphors zoo tuaj yeem muab cov xim kub zoo sib xws thiab cov xim me me ntawm qhov kub thiab txias, yog li txhim kho cov xim rendering Performance index. 12
Kev tsav tsheb tam sim no tseem yuav cuam tshuam cov xim rendering Performance index ntawm LED teeb. Kev tsav tsheb loj dua tam sim no yuav ua rau cov xim kub txav mus rau cov xim kub dua, yog li txo cov xim rendering Performance index.
Lub tshav kub dissipation system ntawm LED kuj muaj qee yam cuam tshuam rau cov xim rendering Performance index. Ib qho kev txhim khu kev qha tshav kub dissipation tuaj yeem ua kom muaj kev ruaj ntseg ntawm LED teeb thiab txo lub teeb attenuation thiab xim rendering Performance index poob los ntawm kub nce.
Kev faib tawm spectral ntawm lub teeb ci yog qhov tseem ceeb hauv kev txiav txim siab xim rendering Performance index. Qhov kev faib ua feem thiab kev siv ntawm ntau yam xim muaj nyob rau hauv spectrum ncaj qha cuam tshuam rau cov xim rendering Performance index. Qhov dav ntawm qhov spectral faib, qhov siab dua cov xim rendering Performance index, thiab ntau qhov tseeb ntawm cov xim.
