Through the knowledge of luminous efficiency of solar radiation it is possible to derive the values of illumination from the known values of solar radiation. This is important in view of the scarcity of luminous data and easy availability of radiation data. In this paper the author presents the computed results of luminous efficiency for the direct component of solar radiation over varied solar altitudes and atmospheric turbidity conditions.
This will enable the computation of the externally reflected daylight in buildings which is considerable in tropics. The luminous efficiency of diffuse radiation will be dealt with in a later paper.
