摘要(Abstract):

为保障全天候的安全飞行,飞机驾驶舱指示灯的亮度需随外部环境的变化而改变,使其上的信息在所有情况下能够被迅速识别且不会干扰飞行员。本文调研民用飞机相关的国内外行业标准与各机型的驾驶舱指示灯光性能需求,通过发光二极管(Light Emitting Diode, LED)特性分析比较了不同的调光方式、通过指示灯样件的光性能测试得出模拟调光的应用方法,为后续新机型指示灯的调光设计以及指示灯产品的国产化研制提供参考依据。
In order to ensure the flight safety under all kinds of illumination conditions, the luminance of the indicators in the aircraft cockpit needs to change with the change of external environment, which could make the pilot recognize the indicators' information as quickly as possible and would not influence the vision of the pilot. This paper refered to the domestic and international standards related to civil aviation and the parameters of the existing aircrafts. It compared different dimming control methods according to the characteristic of LED. The conclusion of analog dimming control application technique was based on the experiments of indicator samples. It provides reference for the indicator dimming control design in the new types of aircrafts and the development of localized indicators.
