照度计算参数的确定

Parameter Determination in Illuminance Calculation

给出了照度计算中水平角、垂直角和高度的通用计算公式，证明了该组公式对仰角安装、俯角安装及水平角安装都是适用的．

General calculating formulas of the horizontal angle,vertical angle and height in the illuminance calculation are given in this paper.It is shown that the erecting of the lamp without elevation angle is a special example of the lamp erecting with elevation angle.
