Aircraft Exterior Light Warning Foldable Wing Tip Movement

The patent employs distinct color changes in the light output to indicate different wing tip states and movements. The system uses at least two different colors to represent folded and extended positions, and changes color dynamically during movement transitions. This color-coding approach makes the wing tip movement clearly visible and distinguishable from other aircraft lighting signals, directly addressing the information communication problem while enhancing safety.

The patent implements periodic light flashing patterns to indicate wing tip movement. During transitions between folded and extended positions, the light emits periodic flashes that draw attention to the changing wing span. This periodic action creates a distinctive visual signal that effectively communicates movement to ground personnel and other aircraft, resolving the information loss issue without compromising safety.

The system uses unique color combinations and transitions that are distinct from standard navigation (red/green/white) and anti-collision (white strobe) lighting. By employing non-traditional colors or specific color transition sequences, the wing tip movement indicator creates a visually distinguishable signal that prevents confusion with other aircraft lights while maintaining high visibility for safety.

The patent uses specific periodic flashing patterns at characteristic frequencies to indicate wing tip movement. These periodic patterns are distinct from the continuous or different-frequency patterns of other aircraft lighting systems. The periodic action creates a recognizable rhythm that helps observers differentiate the wing tip indicator from other lights, preventing information confusion while enhancing safety through attention-drawing signals.
