An Approach to Control the Illuminance Distribution on Vertical Display Surfaces

Abstract

In museum exhibition halls, two-dimensional artworks are displayed usually on vertical surfaces. The uniformity of illuminance distribution in the exhibition area is significant. The control of the illuminance distribution depends on the dimensions of the exhibition hall, the size and location of the exhibition area, and the type, luminous intensity distribution, and position of the luminaire. This study aims to identify the optimal conditions to acquire the targeted illuminance uniformity. For this purpose, sixteen situations were composed concerning four different heights of the exhibition hall and four exhibition areas of various sizes. The luminaires used in the investigation were small and linear with symmetrical and asymmetrical luminous intensity distributions. The position of each luminaire was arranged in the mentioned sixteen situations to obtain optimum conditions. The comparison of the results referred to the energy consumption.
