Heesoo Kim (김희수) and Byeongjin Kim (김병진) presented a paper entitled “Lighting Cube: A Lighting Experiment Unit for Product Lighting Design Exploration,” at the 2025 Annual Autumn Conference of the Korean Institute of Illumination and Electrical Installation Engineers (한국조명·전기설비학회), held in Buyeo (부여). The study introduced the Lighting Cube, a compact experimental unit developed to evaluate the aesthetic harmony between light and object color. By providing a controlled and repeatable environment, the Lighting Cube enables designers and researchers to systematically explore light–color interactions in product design. The presentation was well received by attendees, who commented it as a new and promising approach to conducting lighting experiments and expressed strong interest in future studies utilizing the Lighting Cube.

Abstract

We introduced the Lighting Cube, a compact experimental unit developed to evaluate the aesthetic harmony between light and object color in product design. The cube, built with a modular acrylic structure and equipped with RGBW LEDs, was designed with three key considerations: morphological validity, optical reproducibility, and experimental convenience. It provides a controlled and repeatable environment that enables designers and researchers to systematically explore light–color interactions and assess aesthetic harmony under various lighting and material conditions. Beyond serving as a research tool, the Lighting Cube offers a practical platform for product designers to experiment with lighting scenarios and develop design guidelines for achieving color–light harmony.
