Índice de Reproducción Cromático

IRC o CRI, Chromatic Reproduction Index

Es un coeficiente que se utiliza para medir la calidad de una fuente lumínica creada por el hombre respecto a una ideal, el sol. Si el CRI de un artefacto de iluminación es alto (tiende al 100%) reproducirá bien los colores; siendo similar al efecto de la luz del sol.

Los LED de colores tienen CRI bajo, pues iluminan solo en su espectro cromático.

Es la combinación de los diferentes LED que «Simula» los colores ante nuestra retina.

Por más que mezclemos verde con rojo para lograr amarillo, un objeto amarillo no se verá así si está iluminado solo por esa luz. Si el amarillo es puro (es decir que no tiene pigmentación verde o roja por ejemplo en su pintura) el objeto deberá verse negro.

Tecnología de Lámparas

Se busca un CRI o IRC elevado en aplicaciones donde son importantes los colores, por ejemplo para pintar, fotografía y cine. Aunque para los últimos dos se suela tonalizar aplicando filtros o con LED de color.

6000°k - 5000°k - 4000°k - 3000°k - 2000°k

La temperatura de color se mide en grados Kelvin y se refiere a las distintas tonalidades que puede tener una luz. Las más comunes son estas tres: Luz cálida. Se trata de luces amarillentas y su temperatura de color está por debajo de los 3300K, aunque las más cálidas y habituales están entre 2700 – 2800K
