A fundamental study on introducing daylight into room by combination of the flat prism daylighting system which is one of the daylighting systems and light transmittance ducts is descried in this paper. Artificial light (simulated to the sun light) was introduced into the light transmittance ducts and illuminance and luminance of the transmitted light were measured and then light transmission efficiency was calculated at several variation length of the light transmittance ducts and incident light angle. As the results of the experiments, for practical design, equations for estimation of light transmission efficiency are proposed regard to variation of length of the light duct and incident light angle.
