摘要
针对现代飞机驾驶舱照明对均匀性、舒适性要求的提高,以及现有手动亮度调节方式费时、执行效率低的不足,本文提出一种飞机导光板照明亮度自动调节系统,该系统以光照传感器检测环境光照度,根据亮度控制模型计算驾驶舱内各路导光板亮度,并利用PWM脉宽调制技术调节导光板在当前环境光下的亮度,具有功耗低、调光过程光色一致性好等优点,保证驾驶舱照明环境的均匀、舒适,且具有好的视觉工效。
To address the increasing requirement of uniformity and comfort of aircraft cockpit lighting, and resolve the efficiency issue of time-consuming manual dimming, auto-dimming system of light plate illumination for aircraft cockpit has been proposed. The background luminance is measured with light sensors, and based on the light control model and the background luminance, each light plate illumination is computed. Light plate illumination in the current environment light is adjusted by PWM technique. The advantages of the system include low power consumption and good chroma consistency, etc. The uniformity and convenience of aircraft cockpit illumination can be guaranteed, and good visual effect can be provided.
