Nu er flere og flere mennesker opm\u00e6rksomme p\u00e5 farvegengivelsesindekset (CRI), men de f\u00e6rreste ved, hvad R9 er. Faktisk er CRI og R9 to meget vigtige faktorer, n\u00e5r du v\u00e6lger belysning.<\/p>\n\n\n\n

Hvad er CRI R9?<\/h2>\n\n\n\n

CRI R9 er en af testfarvepr\u00f8verne (TCS), der bruges til beregning af udvidet CRI. Mange producenter vil dog kun rapportere generel CRI, som ikke inkluderer CRI R9-score.<\/p>\n\n\n\n

R9 er en score, der angiver, hvor n\u00f8jagtigt en lyskilde gengiver en st\u00e6rk r\u00f8d farve, og R9<\/a> er faktisk meget vigtig, n\u00e5r man taler om LED-lyskvalitet. Faktisk findes der en vis procentdel R9 i alle farver, der udg\u00f8r CRI-v\u00e6rdien, men et belysningsprodukts specifikke evne til n\u00f8jagtigt at gengive r\u00f8dt er afg\u00f8rende for den n\u00f8jagtige generelle farvegengivelse.<\/p>\n\n\n

Hvorfor er CRI R9 vigtig?<\/h2>\n\n\n\n

CRI R9 er en meget vigtig metrik, faktisk vil mange lyskilder mangle r\u00f8dt indhold, men da R9 ikke indg\u00e5r i gennemsnittet beregnet af CRI, vises det sj\u00e6ldent.<\/p>\n\n\n\n

Som det fremg\u00e5r af nedenst\u00e5ende diagram, kan en lyskilde faktisk klare sig ganske godt med de f\u00f8rste 8 testfarvepr\u00f8ver, idet den scorer ganske godt for R1-R8. For den generelle CRI Ra-metrik betyder dette, at en LED med d\u00e5rlig r\u00f8d farvegengivelse stadig kan klare sig med en 80 CRI-v\u00e6rdi (Ra)<\/a>.<\/p>\n\n\n

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

Men n\u00e5r vi ser n\u00e6rmere p\u00e5 R9-v\u00e6rdien, kan vi se, at lysydelsen er meget d\u00e5rlig, is\u00e6r for den r\u00f8de.<\/p>\n\n\n\n

Hvad er en god CRI R9 v\u00e6rdi?<\/h2>\n\n\n\n

Den maksimalt mulige v\u00e6rdi af R9 er 100, men i mods\u00e6tning til det gennemsnitlige CRI-tal vil bed\u00f8mmelsen af R9 v\u00e6re lidt anderledes.<\/p>\n\n\n\n

Matematisk er R9 sv\u00e6rere at score h\u00f8jt end de andre R-v\u00e6rdier, der udg\u00f8r CRI-beregningen, den er mere f\u00f8lsom overfor spektrale \u00e6ndringer. Derfor ville en R9-score p\u00e5 50 eller derover blive betragtet som "god", mens en R9-score p\u00e5 90 eller derover ville blive betragtet som "fremragende".<\/p>\n\n\n\n

Som et resultat vil du opdage, at de fleste belysningsprodukter p\u00e5 markedet sj\u00e6ldent angiver en R9-v\u00e6rdi, og selvom den g\u00f8r det, er den normalt ikke h\u00f8jere end 50.<\/p>\n\n\n\n

Hvorfor er r\u00f8d s\u00e5 vigtig?<\/h2>\n\n\n\n

R\u00f8d er p\u00e5kr\u00e6vet i mange applikationer, s\u00e5som fotografering, tekstiler og gengivelse af menneskelige hudtoner. Nogle gange er genstande, der ikke ser r\u00f8de ud for os, faktisk kombinationer af farver, inklusive r\u00f8d. For eksempel er hudtonen i h\u00f8j grad p\u00e5virket af r\u00f8dmen af blodet, der str\u00f8mmer under vores hud.<\/p>\n\n\n\n

Derfor kan manglen p\u00e5 r\u00f8dt lys f\u00e5 folk til at se blege ud, endda lidt gr\u00f8nlige, s\u00e5 det er i fotografering eller andre applikationer som medicin, det \u00e6stetiske udseende er afg\u00f8rende, og mange gange kan det ikke rettes selv i efterproduktion og digital redigering .<\/p>\n\n\n\n

Farvegengivelsesindekset og R9-v\u00e6rdierne er to vigtige funktioner, n\u00e5r det kommer til at v\u00e6lge de rigtige LED-lys til din applikation.<\/p>","protected":false},"excerpt":{"rendered":"
