Lighting Design approaches for Round-relief Wood Sculpture

Abstract

This research aims to propose guidelines for lighting design approaches for round-relief wood sculptures to enhance the sculptures’ characteristics and make them more prominent and attractive. The study is expected to benefit designers, curators, and related personnel for museum exhibition planning. The criteria and variables were studied according to the guidelines called The Lighting Design Objectives (LiDOs) through lighting simulation using DIALux evo 13 software. 4 lighting simulations were performed under 30 different lighting conditions, and 3 levels of the reflection coefficient of the surface inside the room ( ), totaling 90 results. Moreover, also takes into account the conservation of the exhibits.

The study results found that the two-lamp lighting pattern, key light with fill light, received higher evaluations than the key light alone, especially when the key light from the front with fill light from the side. Additionally, the value of reflection coefficient of the surface ( ) inside the exhibition room is another factor that designers should consider in conjunction with lighting conditions. Furthermore, if the maximum illuminance on the sculpture’s surface ( ) ranges between 200–500 lux, the number of exhibition days or hours should be reduced or should control the annual luminous exposure in vertical ( ) so it does not exceed the conservation standards. However, these approaches ultimately depend on the preferences of designers, curators, and museum personnel as well.
