摘要
为了提高现行船舶号灯在复杂光环境中的可识别性,更好地保障船舶夜航安全,运用色度学及半导体激光器的发光原理,设计了一种新型船舶号灯.选取长度大于等于50 m的机动船的右舷灯和桅灯为实验对象,在三维实体建模软件(Lighttools)环境下建立右舷灯和桅灯的实体模型,并对这2种号灯的半导体激光器光谱区波长、光谱权重、功率、光线数量、光线追迹阈值等参数进行设置,模拟了不同接收距离处灯光的颜色属性.模拟结果表明:半导体激光号灯右舷灯颜色刺激纯度为1;半导体激光号灯中桅灯光色的色品坐标与参考白光(色品坐标为(1/3,1/3))接近,二者均符合《国际海上避碰规则》对号灯颜色属性的要求.
Abstract
In order to improve the recognizability of ship lights in the complex light environment to better protect the navigation safety of the ship at night,a new type of ship lights was designed according to the colorimetry and the emitting principle of semiconductor laser.Starboard light and masthead light of power-driven vessel with the length of no less than 50 m were selected as experimental objects.Starboard light and masthead light solid models were established in the three-dimensional solid modeling software(Lighttools)environment.Both of the lights semiconductor laser spectral region,spectral weight,power,rays to trace,relative ray power threshold and other parameters were set to simulate the color properties at different reception distances.The simulation results show that:the color stimuli purity value of semiconductor laser starboard light is 1;the chromaticity coordinates of the semiconductor laser masthead light are close to the reference white(the chromaticity coordinates is(1/3,1/3));both of them meet the requirements of the International Regulations for Preventing Collisions at Sea for lights color properties.
