Xim kub yog qhov tseem ceeb thaum txiav txim siab yuav LED teeb. Kab lus no yuav qhia koj tias qhov kub thiab txias yog li cas thiab xaiv qhov zoo rau koj lub teeb LED.
1. Xim kub yog dab tsi?
Xim kub (CCT) sawv cev rau cov xim ntawm lub teeb los ntawm cov khoom teeb pom kev zoo, piav txog qhov sov (daj tsos) lossis txias (xiav tsos) xim ntawm lub teeb ci. CCT yog ntsuas nyob rau hauv units ntawm Kelvin, nrog cov zauv ntau dua qhia bluer los yog "cooler" hues xws li fluorescent hlab siv nyob rau hauv industrial chaw (3100K txog 4500K), qis tus lej qhia cov txiv kab ntxwv, yellower, txias xim ntawm qub incandescent teeb mos, "sov. " tone teeb (2000K txog 3000K).
Piav qhia txog seb lub hnub ci ua haujlwm li cas, lub hnub hloov xim txhua hnub, ntsuas hauv degrees Kelvin. Kev nyeem ntawv ib nrab hnub yuav yog 6000K, lossis lub ci xiav-dawb, thaum lub hnub poob qhov kub thiab txias yuav poob qis dua 3000K rau lub teeb ci ntsa iab heev.
Correlated Xim Kub (CCT)
Cov txheej txheem "blackbody" txhais ntawm cov xim kub thaum xub thawj siv rau cov qhov muag teev teeb pom kev zoo vim tias cov txheej txheem thermal tawg lawv tsim lub teeb zoo ib yam li blackbody radiators. Txawm li cas los xij, cov thev naus laus zis tshiab tshiab xws li cov teeb fluorescent thiab LEDs tsis tsim lub teeb tib yam, yog li yuav tsum muaj ib txoj hauv kev los ntsuas lawv cov teeb pom kev zoo ntawm tib qhov ntsuas uas txhua tus neeg siv tau. Yog li ntawd, cov teeb pom kev zoo no tau muab qhov kev ntsuas hloov kho hu ua correlated xim kub, uas muab tso rau hauv tib qhov kev sib piv ntawm cov teeb pom kev zoo.
Vim li cas CCT mus ntawm "sov" (daj) mus rau "txias" (xiav) thaum qhov tseeb qhov kub ntawm qhov qis mus rau qhov siab? Qhov tsis txaus ntseeg no tsis yog tsuas yog nyob rau hauv kev yees duab xwb, tab sis txhua qhov chaw ntawm cov xim teeb pom kev zoo tau hais. "Txias" yog txuam nrog cov xim xiav tsuas yog vim tib neeg lub hlwb koom nrog cov khoom txias xws li daus. Ntawm qhov tod tes, peb nyiam koom nrog "kev sov siab" nrog cov xim ntawm cov nplaim taws lossis lub ntsiab lus sov so zoo li lub chaw pw hav zoov.
Cia peb ua piv txwv ntawm cov nplaim xiav (uas kub kub dua li cov nplaim liab lossis daj) suav tias yog qhov kub tshaj plaws. Nws ua rau peb nco tias vim li cas "xiav xiav" thiab "liab kub" zoo ib yam li Kelvin tus lej nyob rau hauv cov lus qhia.
CRI, tseem hu ua Xim Rendering Index, yog ib qho tseem ceeb illuminance specification uas kwv yees lub peev xwm ntawm lub teeb ci kom pom tseeb xim ntawm cov khoom nws illuminates. Hauv cov ntawv thov xim tseem ceeb xws li chav ua haujlwm thiab kev kho kom zoo nkauj, qhov chaw teeb pom kev zoo yuav tsum muaj qhov ntsuas xim siab.
100 yog qhov siab tshaj plaws "cov qhab nia" rau kev muaj xim zoo heev, nthuav tawm dab tsi tuaj yeem pom hauv lub hnub ci ci. Yog li txhua yam teeb pom kev zoo tuaj yeem pom xim.
