ON ILLUMINANCE CALCULATION OVER WORKING PLANE IN A ROOM CONTAINING FIXTURES

摘要

This paper describes an approximate calculation of working plane illuminance in a room containing fixtures. For this evaluation, working plane illuminance in a room calculated vary the position of light source. We present results that the approximate values have strinkingly good agreements with the exact values for the average illuminance and illuminance distribution over working plane, and the computation time is much shorter.
