In the underwater attenuation environment, it is hard to achieve high uniformity in a long illumination range for the optical designed based on a certain illumination distance. This paper proposes an optical design method of multi-regional illumination in seawater, which makes the different areas be illuminated with different luminous fluxes at different distances to expand the distance range of uniform illumination. In the lighting design example of this paper, this paper realizes high illumination uniformity lighting from 1 to 10 meters. The illumination uniformity is defined as the ratio of the minimum illuminance value to the average illuminance value. Compared with the traditional design method, the illumination uniformity of this method in the lighting distance exceeds 0.7, while the minimum illumination uniformity is less than 0.4 in the traditional illumination system..
