    • A new and useful lighting system is provided, that is particularly useful as a lighting system for a deck (e.g. a ship deck), where pilots taking off from or landing on the deck often use night vision goggles. In addition, a new and useful optical projection structure for a portion of the lighting system is provided. The lighting system comprises at least a pair of lighting subsystems that project light to a volume space with different spatial distributions. One subsystem projects light to the volume space with a predetermined spatial distribution, and the other lighting subsystem projects light to the volume space with a different spatial distribution, in a manner that effectively supplements the projected light from the first subsystem, so as to provide a lighting system that effectively illuminates the entire volume space. Moreover, the system is designed to be particularly compatible with the optical capabilities of night vision goggles. The system is designed to substantially filter out light in a predetermined wavelength band that is “out of band” of night vision goggles (i.e. the wavelength band at which light vision goggles operate), so that the projected light effectively illuminates the deck, and does not interfere with the vision of pilots who are using night vision goggles. The new optical projection structure is particularly useful in projecting light from a source (e.g. an array of light emitting diodes [“LEDs”]) to a volume space, while minimizing the overall size of the projection structure, and maintaining good projection efficiency.
    • 提供了一种新的和有用的照明系统,其特别用作用于甲板(例如船甲板)的照明系统,其中从甲板起飞或着陆的飞行员经常使用夜视镜。 此外,提供了一种用于照明系统的一部分的新的和有用的光学投影结构。 照明系统包括至少一对将光照射到具有不同空间分布的体积空间的照明子系统。 一个子系统以预定的空间分布将光投射到体积空间,而另一个照明子系统以有效地补充来自第一子系统的投射光的方式将具有不同空间分布的光投射到体积空间,以便提供 照明系统有效照亮整个音量空间。 此外,该系统被设计为与夜视镜的光学能力特别兼容。 该系统被设计为基本上过滤掉在夜视镜(即,光视觉护目镜操作的波长带)的“带外”的预定波长带中的光,使得投射的光有效地照射甲板,并且 不妨碍使用夜视镜的飞行员的视野。 新的光学投影结构特别可用于将来自源(例如发光二极管阵列(“LED”])的光投射到体积空间,同时最小化投影结构的总体尺寸,并保持良好的投影效率。
