Taesu Kim, a Ph.D. student of Color lab, delivered an online presentation entitled as, “Bus Interior Lighting Design Using Detachable Ceiling Light Module” at the 2020 Fall International Conference of Korea Society of Design Studies(KSDS). This study introduced the use of scale mockups to prototype the lighting design quickly but much more realistic than drawings or 3D simulated renderings. He proposed ten concepts about emotional ceiling light optimized for the premium bus. Thankfully, both Dr.Kyungah Choi and Dr.Kyeong Ah Jeong have helped the research process with their expertise in emotional lighting.
