| 为了对灯具设计效果进行评价，提出了一种快速评价方法。基于实际灯具光强的实测数据，利用软件仿真来获得受照面的照明效果，从而有效控制误差和降低成本。对单个灯具在自由摆放位置和旋转角度的条件下，利用网格法划分受照面，由光度学理论计算得到受照面的照度分布。依据几何光学独立性，扩展到总体方案的照度分布。将照明效果用照度曲线和图像显示，从而对灯具设计状况获得快速、有效、直观的评价。为使图像更具直观性和有效性，提出了图像颜色随照度变化近似满足人眼gamma特性。以研制的天幕灯为例，证明了该方法的可行性。 |

| A method for the evaluation of the optical design for lamps is proposed.Based on the measured datum of the luminous intensity of the lamps,the method evaluates the by software,so it controls error and reduces the cost effectively.For a single lamp on random position and with random rotation angle,a surface approximation scheme with a rectangular mesh is adopted and the irradiance distribution by the theory of photometry is calculated.According to the independence of the geometrical optics,the result can be extended to the overall scheme.a fast,effective,intuitive evaluation can be made by the illumination curves and picture which show the luminous effect on the surface.Besides,the change of the color on the picture by the irradiance distribution that meets the gamma curve for the human eye approximately is proposed,which may make the picture more intuitive and effective.As an example application,the simulation of a newly designed cyclorama light is presented to prove the feasibility of this method. |
