It is a commonplace for interior design to add luminaires onto lighting design. To inquire about alternatives, this research embarked on an alleged lamp-less lighting design expedition. The rationale for such an exploration is to keep up with the ongoing global research heat on OLED studies-even though the emitted high brightness is the underdog among light sources in terms of energy efficiency. Under such a scenario, this study collected and employed OLED lamp samples with distinguishable photometric and colorimetric parameters on a 3D interior space for DIALux EVO calculation and ray tracing effects. It is observable from these design tests, that OLED mini-meter thin panels can be integrated into interior constituent elements to come up with flexible and brand new lighting ambiences.
