This paper proposes a novel approach to spatial illumination calculation by experiments. Existing researches on illumination calculations have these problems such as large errors in the calculation of optical metrics, and there are great limitations in the spatial form and layout of devices. In order to solve these problems, based on the light distribution curve and the law of Lambertian reflectance, the spatial illumination can be obtained, and the mathematical model of a complex spatial light environment with more accurate calculation results and wider application range was established and implemented by MATLAB. Finally, it is used in the illumination calculation simulation of different spatial models. After calculation, the average illumination intensity calculation of space work surface is compared with that of DIALux results. The error is within ±3%, the distribution of plane illumination curves is basically the same, and the solution to the circular bottom surface space, the unequal height of the bottom spatial light environment cannot directly describe the problem.
