Abstract
A night vision compatible edge-light is disclosed. The edge-light may include high efficiency white LEDs alternated with filtered multi-die or compact clustered color LEDs to provide a dual-mode configuration. For example, the filtered color LED modules may be energized in order to provide a night vision compatible mode of operation. That is, the filtered color LED modules may provide illumination so that the display is not only visible to unaided eyes, but also compatible with night vision equipment (e.g., night vision goggles) without adversely affecting the operation of the night vision equipment. On the other hand, the unfiltered white LED modules may be energized to provide illumination suitable for relatively bright operation conditions (e.g., in daylight or when sufficient ambient lights are available). Furthermore, both the white LEDs and the color LEDs may be energized simultaneously to enhance the day mode if so desired.
