AI Technical Summary
Existing lighting systems for liquid crystal matrix displays in aircraft cockpits face challenges in achieving uniform backlighting for both daytime and nighttime modes, particularly in maintaining optical quality and compatibility with Night Vision Imaging Systems (NVIS), due to constraints in diode spacing and light diffusion homogeneity.
A lighting system utilizing a main right prism light guide with two independent optical injection pathways, each optimized for daytime and nighttime modes, where the light guide has structured injection windows for each source, allowing for clean lateral injection and optimal placement of diodes without interference, enabling efficient light transmission and homogenous diffusion.
This solution achieves highly compact and efficient lighting with optimized performance for both daytime and nighttime modes, ensuring high-quality light diffusion and reduced luminance loss, while allowing for independent optimization of each mode without compromising the other.
