The Luminaire Luminance Uniformity Apparatus was designed to facilitate human factors investigations of perceived luminance uniformity of luminaire apertures, with the goal of developing luminance uniformity metrics tailored to this application. This presentation outlines the design and key features of the apparatus. This new apparatus will enable new research on perceived luminance uniformity through automated user-control of the distance between an LED array and optical material, manual selection of optical materials, and an automated system that rapidly obtains precise luminance measurements with multiple devices and methods.
