Saving energy in the living life is a pressing need today when the restriction on the earth environment is strict with energy consumption. We examine a lighting environment at the present residence from the illuminance and lighting method. As a result, we show that EL (Elector luminescent) and LED (Light Emitting Diode) has a possibility to become a source of light which is abundant and energy conservation in the next generation.doi:10.2978/jsas.13.72 fatcat:5on5273s2fdw7mzj2qz5qcezlq
