摘　　要：为提高船舶号灯在复杂光环境下的可识别性,选择半导体激光器作为号灯的光源,设计出一种新型船舶号灯。该号灯光束能量集中,容易获得符合《国际海上避碰规则》要求的发光强度和可见距离;通过设计合理的阵列结构,使其能够获得符合《国际海上避碰规则》要求的水平光弧和垂直光弧。在三维实体建模软件(Lighttools)环境下,模拟透射率为0.8时大气散射对新型号灯左舷灯光束传播的影响。结果表明:大气散射能使号灯光束展宽,并使光束内光强分布更加均匀。In order to improve the identifiability of ship navigation lights in complex light environments, a new type of ship navigation lights with semiconductor laser source is designed. The energy of the light beam is concentrated, which makes the luminous intensity and computed visibility easily meet the requirements of International Regulations for Preventing Collisions at Sea. By designing a proper array structure, the new ship lights can meet the requirements of the same regulation about horizontal and vertical light showing arcs. The influence of the atmospheric scattering to the propagation of port side light beam was simulated in the three-dimensional solid modeling software （Lighttools） environment for the circumstance of atmospheric transmittance 0. 8. The simulation results show that atmospheric scattering can broaden the light beam and make intensity distribution of the beam more uniform.
