Standardljusmiljöer

Standardljusmiljöer, often translated as standard lighting environments or standard light conditions, refers to defined sets of spectral power distributions for light sources. These are crucial in fields like colorimetry, photography, and industrial inspection where consistent and reproducible color perception is paramount. The most widely recognized standard lighting environments are established by the International Commission on Illumination (CIE). These standards provide a common reference point, allowing for objective comparison and measurement of how objects appear under specific lighting conditions. Without these standards, the color of an object could vary significantly depending on the light source used for observation, leading to discrepancies and potential errors. For example, a color that appears a certain shade under daylight might look different under artificial light. CIE illuminants, such as CIE Illuminant D65 (representing average daylight) and CIE Illuminant A (representing incandescent lamps), are examples of these standard lighting environments. Each illuminant has a specific spectral power distribution that characterizes its spectral composition. The use of these standardized environments ensures that color measurements and reproductions are consistent and comparable across different locations and times. This standardization is fundamental for industries that rely on accurate color reproduction, including textiles, printing, and digital imaging.
