Nesne aydınlatmasında yeni bir yöntem: Yüzey kromatisite koordinatlarının led tabanlı aydınlatma aracı olarak müzelerde kullanımı

In contemporary museum lighting, the common practice is to choose light sourceswith recommended Color Rendering Indices (CRI) and Color Temperatures (CT)that do not emit harmful wavelengths: ultraviolet and infrared. In addition to CRI andCT, the commonly disregarded component of each light source, the ChromaticityCoordinates (CC), do not exist in any guidelines that are intended to be used bymuseum lighting designers and curators. This thesis aims to create a guideline forthe museum lighting designers by proposing a new lighting method based on therelation between the surface CC of the museum objects and the CC of the lightsources that are proposed to be their illuminators. For this reason, an experimentwas conducted by using the Light-Emitting Diodes (LEDs) and computerized lightingcontrolled systems to test the validity of the proposed method. In the study, theappearances of the colored objects under a D65 reference light source wereevaluated by comparing the created light source with their CC values and threeother LED light sources with CT of 3000, 4200, and 6500 Kelvin that are mainlyused in the museum lighting design applications. The results of the experimentshowed that subjects preferred the appearance of the objects under lights that havesame CC as the object. This thesis contributes to the museum lighting literature bycreating the basis for a guideline for choosing and creating unique light sources forobjects, by using their own physical properties.Keywords: Chromaticity Coordinates, Light Emitting Diodes (LED), MuseumLightingiii
