A Study on the Luminous Efficacy of Solar Radiation in Seoul Area |
| Abstract |
A luminous efficacy, the correlation between ilumination and radiation, is necessary to predict illumination data from radiation data. In this study grobal radiation and grobal illumintion were measured to calculated luminous efficacy according to sky condition. The sky condition was classified by cloud ratio calculated from diffuse radiation and grobal radiation. By analyzing measured data, the luminous efficacy of radiation in Seoul area is 103-136 lm/W under the clear sky, and 116-136 lm/W under the overcast sky during the period of measurement. |
