Wat is CRI R9?<\/h2>\n\n\n\n

CRI R9 is een van de testkleurstalen (TCS) die worden gebruikt bij de berekening van uitgebreide CRI. Veel fabrikanten zullen echter alleen algemene CRI rapporteren, waarin de CRI R9-score niet is opgenomen.<\/p>\n\n\n\n

R9 is een score die aangeeft hoe nauwkeurig een lichtbron een sterke rode kleur reproduceert, en R9<\/a> is eigenlijk heel belangrijk bij het bespreken van LED-lichtkwaliteit. In feite wordt een bepaald percentage van R9 aangetroffen in alle kleuren waaruit de CRI-waarde bestaat, maar het specifieke vermogen van een verlichtingsproduct om rood nauwkeurig te reproduceren, is van cruciaal belang voor een nauwkeurige algehele kleurweergave.<\/p>\n\n\n

Waarom is CRI R9 belangrijk?<\/h2>\n\n\n\n

CRI R9 is een zeer belangrijke statistiek, in feite zullen veel lichtbronnen geen rood gehalte hebben, maar aangezien R9 niet is opgenomen in het gemiddelde dat door de CRI wordt berekend, wordt het zelden weergegeven.<\/p>\n\n\n\n

Zoals de onderstaande grafiek laat zien, kan een lichtbron eigenlijk best goed presteren met de eerste 8 testkleurmonsters, en scoort vrij goed voor R1-R8. Voor de algemene CRI Ra-metriek betekent dit dat een LED met slechte rode kleurweergave nog steeds kan volstaan met een 80 CRI (Ra)-classificatie<\/a>.<\/p>\n\n\n

\n
\"\"<\/figure>\n<\/div>\n\n\n

Als we echter goed naar de R9-waarde kijken, zien we dat de lichtprestaties erg slecht zijn, vooral voor de rode.<\/p>\n\n\n\n

Wat is een goede CRI R9-waarde?<\/h2>\n\n\n\n

De maximaal mogelijke waarde van R9 is 100, maar in tegenstelling tot het gemiddelde CRI-getal, zal het oordeel van R9 een beetje anders zijn.<\/p>\n\n\n\n

Wiskundig gezien is R9 moeilijker hoog te scoren dan de andere R-waarden die deel uitmaken van de CRI-berekening, het is gevoeliger voor spectrale veranderingen. Daarom wordt een R9-score van 50 of hoger als "goed" beschouwd, terwijl een R9-score van 90 of hoger als "uitstekend" wordt beschouwd.<\/p>\n\n\n\n

Als gevolg hiervan zult u merken dat de meeste verlichtingsproducten op de markt zelden een R9-waarde specificeren, en zelfs als dat zo is, is deze meestal niet hoger dan 50.<\/p>\n\n\n\n

Waarom is rood zo belangrijk?<\/h2>\n\n\n\n

Rood is vereist in veel toepassingen, zoals fotografie, textiel en reproductie van menselijke huidtinten. Soms zijn objecten die er voor ons niet rood uitzien eigenlijk combinaties van kleuren, waaronder rood. De huidskleur wordt bijvoorbeeld grotendeels be\u00efnvloed door de roodheid van het bloed dat onder onze huid stroomt.<\/p>\n\n\n\n

Daarom kan het gebrek aan rood licht ervoor zorgen dat mensen bleek, zelfs een beetje groenachtig lijken, dus het is in fotografie of andere toepassingen zoals medicijnen, het esthetische uiterlijk is cruciaal en kan vaak niet worden gecorrigeerd, zelfs niet bij postproductie en digitale bewerking .<\/p>\n\n\n\n

De Color Rendering Index en R9-waarden zijn twee belangrijke kenmerken als het gaat om het selecteren van de juiste LED-verlichting voor uw toepassing.<\/p>","protected":false},"excerpt":{"rendered":"
