Error Analysis and Improvement of Luminous Flux Calculation with Sphere-band Method
Xu Haihan
Abstract：After getting the luminous intensity distributions of a lighting source by a goniophotometer system , the total and/or partial luminous flux are usually calculated by sphere-band method.Because of the particularity of spherical coordinate , this method is different from that of plane-coordinate system .The difference and calculation error of this method is analyzed and an improved method is proposed in this paper .
