EXPERIMENTAL EXAMINATION AND SIMULATION OF A LED INTERIOR LIGHTING SPA

摘要

The image-luminance measurements and simulations on an experimental LED interior lighting space were performed and compared. The luminances at some selected points measured by the image luminance measurement device (ILMD) are close to those measured by a spectroradiometer with mean deviation less than -3 %. While the luminances obtained by the simulation are less accurate than those by ILMD. The background luminance (Lb) calculated on whole luminance image are close to those obtained by an illuminance meter. The difference of unified glare rating (UGR) obtained by simulation and by ILMD is averagely within 0,4, and the Pearson's correlation between these two UGR is 0,89.
