Spectroscopic Correlation Analysis ntawm M / P Ratio thiab High Color Rendering Index LED Luminaires
Los ntawm Kevin Rao Kaum Ob Hlis 1, 2025
Kev ntsuam xyuas ntawm spectral tis nyob rau hauv cov khoom siv teeb pom kev zoo yuav tsum muaj kev suav nrog cov tshuaj lom neeg tsis zoo. Qhov M/P piv yog ib qho qhia rau kev ntsuas qhov tsis yog - pom kev lom zem ntawm lub teeb pom kev, thiab nws qhov kev sib raug zoo nrog Xim Rendering Index (CRI) tau dhau los ua qhov tseem ceeb hauv kev ntsuam xyuas.
Lub hauv paus ntsiab lus ntawm kev suav M/P Ratio
Qhov sib piv M / P txhais tau tias yog qhov quotient ntawm melanopic lux faib los ntawm photopic lux. Kev suav yog ua raws li kev ua haujlwm melanopic mel(λ) thiab photopic function V(λ) tau teev tseg hauv CIE S 026 / E: 2018 tus qauv. Kev ntsuas ntsuas yuav tsum ua raws li ISO / CIE 19476: 2014 tus qauv, yuav tsum muaj lub sijhawm ntev ntawm spectral wavelength ntawm 1 nm.
Qhov sib piv M / P ntsuas qhov muaj peev xwm cuam tshuam ntawm lub teeb ci ntawm melatonin suppression. Kev teeb pom kev lag luam tus qauv ANSI/IES TM-18-20 qhia tias M / P piv rau hmo ntuj ua haujlwm teeb pom kev zoo yuav tsum qis dua 0.6.

Spectral yam ntxwv ntawm siab -CRI LEDs
High Colour Rendering Index LEDs ua tiav lawv cov kev ua tau zoo los ntawm ntau-band spectral txhim kho. Ib tug raug CRI 97 LED cov ntaub ntawv peb hluav taws xob peaks ntawm kwv yees li 450 nm, 540 nm, thiab 610 nm. Cov qauv spectral no nce qhov feem ntawm lub zog hluav taws xob hauv 450-480 nm band thaum txhim kho tus nqi R9.
Cov ntaub ntawv ntsuam xyuas qhia tau hais tias ntawm qhov sib txheeb xim kub (CCT) ntawm 3000K, thaum CRI nce ntawm 80 mus rau 95, qhov feem pua ntawm radiant flux hauv 450-480 nm band nce los ntawm 12% mus rau 18%. Cov kab no sib raug rau thaj tsam rhiab heev ntawm kev ua haujlwm melanpic.

Kev soj ntsuam ntawm Engineering Technology Impact
Spectral Design Contradiction
Ua kom tiav CRI siab yuav tsum muaj kev faib tawm txuas ntxiv hauv 600-700 nm band. Cov cuab yeej siv tam sim no txhim kho qhov kev siv zog ntawm cov450nm xiav ntiua kom muaj zog liab phosphors, ua rau kom luv luv - wavelength xiav hluav taws xob. Cov kev ntsuam xyuas qhia tau hais tias rau txhua txhua 10-point nce hauv R9 tus nqi, lub radiant flux ntawm 450 nm nce los ntawm kwv yees li 3.2%.
Biological Effect Optimization Scheme
Siv violet nti excitation tshuab tuaj yeem txo qhov M / P piv. Ua haujlwm 405 nm violet nti nrog tri-phosphors tuaj yeem tswj tau CRI saum 95 thaum txo qis M / P piv rau 0.48. Cov cuab yeej no twb tau siv rau hauv kev kho mob teeb pom kev zoo.
Teeb pom kev zoo tswj lub tswv yim
Cov teeb pom kev ntse ntse dynamically kho cov spectrum raws li circadian rhythms. Hmo ntuj hom txwv qhov kev faib ua feem ntawm 450 nm hluav taws xob kom qis dua 12%, thaum ntxiv illuminance nrog590nm amber LEDs. Qhov system no ua raws li WELL Building Standard L03 clause cov cai.
Application Scenario Guidelines
Chaw ua haujlwm teeb pom kev zoo
Cov chaw ua haujlwm nruab hnub siv cov teeb pom kev zoo nrogCRI siab tshaj 90, nrog M / P ratios tswj nyob rau hauv 0.55-0.65 ntau. Lub rooj sib tham chav teeb pom kev zoo hloov kho spectrum hom: hom kev nthuav qhia txhim kho xim rendering kev ua tau zoo, thaum hmo ntuj lub rooj sib tham hom txo M / P piv.
Kev kho teeb pom kev zoo
Chav tsev neeg mob hmo ntuj teeb pom kev zoo siv cov teeb pom kev tshwj xeeb nrog CRI 80 thiab M / P ratios qis dua 0.4. Kev phais teeb pom kev sib txawv ntawm cov teeb pom kev dav dav dav dav thiab qhov chaw phais teeb pom kev zoo, tom kawg tswj xyuas cov xim zoo nkauj thaum lub teeb pom kev zoo siv qhov chaw qis M / P piv.
Cov qauv teeb pom kev lag luam
Cov chaw ua haujlwm tsis tu ncua siv sijhawm- raws li cov tswv yim teeb pom kev zoo. Thawj ib nrab ntawm hmo ntuj siv siab -CRI teeb pom kev zoo, hloov mus rau qis M/P piv hom tom qab ib tag hmo. Lub illuminance txij nkawm tseem tsis hloov pauv, thaum lub zog spectral faib tau hloov kho raws li qhov kev pab cuam.
FAQ
M/P Ratio Measurement Method
Siv lub spectroradiometer los ntsuas qhov spectral fais fab faib, xam raws li CIE 218-2016 tus qauv. Rau kev ntsuam xyuas sai ntawm qhov chaw, calibrated xiav lub teeb phom sij tuaj yeem siv tau, nrog cov txiaj ntsig tau muab los ntawm kev hloov pauv ntawm 0.82.
Product Specification Labeling Requirements
Cov ntaub ntawv qhia txog cov khoom siv teeb pom kev zoo yuav tsum suav nrog M / P piv tus nqi rau peb CCT cov ntsiab lus: 3000K, 4000K, thiab 5000K. Cov ntaub ntawv xeem yuav tsum tau qhia cov qauv siv thiab ntsuas qhov tsis meej, uas yuav tsum tsawg dua 8%.
Existing System Retrofit Solutions
Yog tsis hloov lub luminaires, txhim kho 475 nm txiav- tawm cov lim dej tuaj yeem txo qhov M / P piv los ntawm 35% -40%. Lim lub teeb poob yog kwv yees li 12%, yuav tsum muaj kev sib txuas ntxiv ntawm cov teeb pom kev zoo tsim tus nqi.
Kev Tshawb Fawb Txog Kev Ua Raws Cai
Lub tsev kho mob teeb pom kev zoo yuav tsum muaj 24-teev melatonin atherosclerosis kev soj ntsuam daim ntawv qhia. Daim ntawv tshaj tawm yuav tsum suav nrog MLT-Kev suav nqi cheeb tsam thiab kev tsom xam lub sijhawm-series, ua raws li Daim Ntawv Ntxiv H ntawm GB 50034-2021.
Yam Khoom Xaiv Kev Txiav Txim Siab
Prioritize compromise solutions with CRI 90-93 and M/P ratios of 0.50-0.55. For special scenarios, use tunable spectrum products with daytime mode CRI >95 thiab hmo ntuj hom M / P<0.45.
