Both non-integrated type and integrated type exist in luminaires with LED or OLED. Since "Flux-unit method" in our previous report was applicable to only non-integrated type, we improved this method to adapt to integrated type by using calculation process of room's total luminaire luminous flux. Therefore, "Flux-unit method" with luminaire luminous flux has become a simple lighting design method that adapts to almost main lamps and luminaires used in the residential building. In this study, trial designs with this method were also executed.
