DCockpit Lighting System Design and Analysis

本文是驾驶舱照明多年设计经验的总结。概括驾驶舱照明设计的重要性,明确驾驶舱照明的目的。通过对白光、红光、蓝白光特性分析,结合飞机使用需求,确定驾驶舱照明光色。对先进民机驾驶舱灯具配置分析,强调设计人员在进行灯具配置时需要考虑的多种因素。最后从调光控制方式选择,晶体调光控制和PWM调光控制原理设计以及防舱内眩光几个方面进行阐述。给新进入这个领域的设计人员有个系统的认识,以缩短设计人员入门的时间,提供工作效率。

This paper illustrates the importance and the purpose of the cockpit lighting system design. By analyzing the characteristics of the white light, the red light and the blue-white light, while integrating the requirements of the aircraft, the color of cockpit lighting system can be determined. This paper also analyzes the configuration of the cockpit lights on modern civil aircraft and emphasizes the factors which should be taken into account. In the end, this paper presents some aspects including the ways of dimming control, the principles of crystal dimming control and PWM dimming control, as well as the methods of anti glare, which gives an overview to the new designers in this area thereby enhancing the efficiency.
