Color Rendition

Color rendition (also commonly referred to as color rendering) is the effect of light on the color perception of objects. The International Commission on Illumination (CIE) defines color rendering as the "effect of an illuminant on the color appearance of objects by conscious or subconscious comparison with their color appearance under a reference illuminant."

Key concepts in understanding color rendition include:

• Human Color Perception: Mutane suna ganin launi lokacin da haske ya shiga ido kuma ya buge retina, wanda ya ƙunshi cones masu kula da launi waɗanda ke sadarwa da kwakwalwa.
• CIE Color Space: Tsarin lissafi da aka ayyana a shekara ta 1931 don ƙididdige duk launukan da idon ɗan adam na iya gani.
• Spectral Power Distribution (SPD): Bayanin tsayin raƙuman hasken wuta wanda ke yin tasiri sosai ga kamannin muhalli da kwarewar gani.
• Color Attributes: Siffofi na asali ciki har da launi (takamaiman launi), daraja (haske/duhu), da chroma (ƙarfi/jikewa).

For some lighting applications, fidelity is the most important quality. For others, considerations such as saturation, hue, or efficiency may be more important. By understanding and applying the various models of color rendition, we can determine which light sources create optimal viewing conditions for different applications—from retail stores to food processing plants, living rooms to hospital operating rooms.

While each color rendition model offers valid means of evaluating LED characteristics, combining several methods—such as CRI plus TM-30—can provide the most complete reference point for architects and lighting designers.

Luminus LEDs tana da ingantacciyar aiki a kowane ma'auni na nunin launi da inganci, suna ba da mafita ga kusan kowane aikace-aikacen haske mai hankali ga launi.
