摘　　要：水下照明设计由于其传播介质的特殊性,在设计和计算时需考虑多方面因素,本设计为水域表面直径23m,水深10m的圆柱形金属桶内水域提供照明,其要点:①照明方式为顶部照明与侧壁照明组合的方式;②光源的选择综合考虑光源的光谱分布和光在水中的衰减等因素,选定顶灯采用400W金卤投光灯,对称配光,窄光束;侧壁照明采用1000W金卤投光灯,对称配光,宽光束;③在均匀度方面,顶部照明在垂直面上的分布比较均匀,侧壁照明靠近水桶边缘的部位均匀度不好。A lot of factors are to be considered for the underwater illumination design and calculation due to its special propagating medium. The design is to provide the illumination for a cylindrical metal barrel inside which is full of water with a diameter of 23m and a depth of 10m. The key design points are discussed which are ① the illumination method is the combination of top illumination with side wall illumination; ② those factors such as the spectral distribution of the light source and the light attenuation in water have been taken into account in combination for the selection of light source and finally the 400W metal halide projecting lamp with symmetrical light and narrow beam has been chosen but for the side wall illumination the 1000W metal halide projecting lamp with symmetrical light and wide beam has been chosen; ③ as to the homogenity the top illumination is well distributed on the vertical plane but the side wall illumination is not well distributed on the location close to the edges of the water barrel.
