Abstract: A wildlife deterrence aircraft lighting apparatus includes at least one species deterrent LED to provide non-lethal deterrence of avian species (i.e., birds) within a deterrence area in an immediate flight path of an aircraft. The species deterrent LED may be configured to emit mono-colored light at a wavelength within a sensitivity range of a short-wavelength-sensitive (SWS) photoreceptor of at least one avian species and with a light intensity in at least a portion of the deterrence area sufficient to induce an augmented behavioral response. The lighting apparatus may also control the species deterrent LED(s) and aircraft lighting LED(s) independently and may provide voltage control and temperature control to enable the wildlife deterrence function without interfering with the aircraft lighting functions. The lighting apparatus may further be configured to reduce luminous flux loss and to provide thermal management to accommodate both wildlife deterrence and aircraft lighting functions.
Abstract: Wildlife deterrence methods and systems use mono-colored light within a sensitivity range of a short-wavelength-sensitive (SWS) photoreceptor of a species to be deterred, such as an avian species. The mono-colored light may be generated by one or more high brightness mono-colored light emitting diodes (LEDs) and may be within 25 nm of a peak absorption wavelength of the SWS photoreceptor of the species. The mono-colored light is directed to a deterrence area with an intensity sufficient to cause at least a temporary disruption of visual perception in the species to induce an augmented behavioral response in the species resulting in avoidance of the deterrence area. The mono-colored light may also be generated as intermittent pulses having a duration sufficient to keep a pupil of an eye of the species in a continuous unstable state to prevent light adaption by the species.
