Aujourd'hui, de plus en plus de gens pr\u00eatent attention \u00e0 l'indice de rendu des couleurs (IRC), mais peu de gens savent ce qu'est R9. En fait, IRC et R9 sont deux facteurs tr\u00e8s importants lorsque vous choisissez un \u00e9clairage.<\/p>\n\n\n\n

Qu'est-ce que l'IRC R9 ?<\/h2>\n\n\n\n

L'IRC R9 est l'un des \u00e9chantillons de couleur de test (TCS) utilis\u00e9 dans le calcul de l'IRC \u00e9tendu. Cependant, de nombreux fabricants ne rapporteront que l'IRC g\u00e9n\u00e9ral, ce qui n'inclut pas le score IRC R9.<\/p>\n\n\n\n

R9 est un score qui repr\u00e9sente la pr\u00e9cision avec laquelle une source lumineuse reproduit une couleur rouge intense, et R9<\/a> est en fait tr\u00e8s important lorsqu'on parle de la qualit\u00e9 de la lumi\u00e8re LED. En fait, un certain pourcentage de R9 est pr\u00e9sent dans toutes les couleurs qui composent l'IRC, mais la capacit\u00e9 sp\u00e9cifique d'un produit d'\u00e9clairage \u00e0 reproduire fid\u00e8lement le rouge est essentielle \u00e0 la pr\u00e9cision du rendu global des couleurs.<\/p>\n\n\n

Pourquoi l'IRC R9 est-il important\u00a0?<\/h2>\n\n\n\n

CRI R9 est une mesure tr\u00e8s importante, en fait de nombreuses sources lumineuses manqueront de contenu rouge, mais comme R9 n'est pas inclus dans la moyenne calcul\u00e9e par le CRI, il est rarement affich\u00e9.<\/p>\n\n\n\n

Comme le montre le tableau ci-dessous, une source lumineuse peut en fait obtenir d'assez bons r\u00e9sultats avec les 8 premiers \u00e9chantillons de couleurs test\u00e9s, en obtenant de bonnes notes pour R1-R8. Pour la mesure g\u00e9n\u00e9rale de l'IRC Ra, cela signifie qu'une LED dont le rendu des couleurs rouges est m\u00e9diocre peut encore s'en sortir avec un IRC Ra. 80 CRI (Ra)<\/a>.<\/p>\n\n\n

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

Cependant, quand on regarde de pr\u00e8s la valeur R9, on peut voir que les performances lumineuses sont tr\u00e8s m\u00e9diocres, surtout pour le rouge.<\/p>\n\n\n\n

Qu'est-ce qu'une bonne valeur CRI R9\u00a0?<\/h2>\n\n\n\n

La valeur maximale possible de R9 est de 100, mais contrairement au nombre CRI moyen, le jugement de R9 sera un peu diff\u00e9rent.<\/p>\n\n\n\n

Math\u00e9matiquement, R9 est plus difficile \u00e0 obtenir que les autres valeurs R qui composent le calcul de l'IRC, il est plus sensible aux changements spectraux. Par cons\u00e9quent, un score R9 de 50 ou plus serait consid\u00e9r\u00e9 comme "bon", tandis qu'un score R9 de 90 ou plus serait consid\u00e9r\u00e9 comme "excellent".<\/p>\n\n\n\n

En cons\u00e9quence, vous constaterez que la plupart des produits d'\u00e9clairage sur le march\u00e9 sp\u00e9cifient rarement une valeur R9, et m\u00eame si c'est le cas, elle n'est g\u00e9n\u00e9ralement pas sup\u00e9rieure \u00e0 50.<\/p>\n\n\n\n

Pourquoi le rouge est-il si important ?<\/h2>\n\n\n\n

Le rouge est requis dans de nombreuses applications, telles que la photographie, les textiles et la reproduction des tons de peau humaine. Parfois, les objets qui ne nous semblent pas rouges sont en fait des combinaisons de couleurs, y compris le rouge. Par exemple, le teint de la peau est largement affect\u00e9 par la rougeur du sang qui coule sous notre peau.<\/p>\n\n\n\n

Par cons\u00e9quent, le manque de lumi\u00e8re rouge peut rendre les gens p\u00e2les, voire un peu verd\u00e2tres, c'est pourquoi en photographie ou dans d'autres applications telles que la m\u00e9decine, l'aspect esth\u00e9tique est crucial et ne peut souvent pas \u00eatre corrig\u00e9 m\u00eame en post-production et en \u00e9dition num\u00e9rique. .<\/p>\n\n\n\n

L'indice de rendu des couleurs et les valeurs R9 sont deux caract\u00e9ristiques importantes lorsqu'il s'agit de s\u00e9lectionner les bons \u00e9clairages LED pour votre application.<\/p>","protected":false},"excerpt":{"rendered":"
