The theory to calculate mean illuminance has been considered, and the calculating methods are almost systematically constructed. But the errors which often occur in the calculation are treated qualitatively, not quantitatively. Here they are precisely examined, and estimated in some formulas, which separate these errors in to two cases: (1) errors in the measuring, and (2) errors in the calculation neglecting higher order component of real illuminance.
Above is confirmed theoretically, and also numerically in a simple experiment. Light distribution is also investigated relating to mean illuminance, but the problems wait for perfect solution in future.
