Portable aircraft landing zone lighting apparatus and system
Lightweight and man-portable lights may be used to provide a rapid and deployable aircraft landing zone illumination solution. The lights may produce a combination of visible and infrared (IR) light. The lights may be mounted using stakes or concrete anchors, or they can be left unmounted on the ground for easy and rapid deployment. The light may include five types of visible light-emitting diodes (LEDs)—white (W), yellow (Y), green (G), red (R), and blue (B)—and infrared (IR) LEDs. The LEDs (visible and IR) can be controllable between different intensities. The light may include built-in wireless communication capabilities. A number of lights may be positioned and then operated together for landing zone and emergency lighting solutions.
1. A portable light comprising:
a housing including
a lighting shelf including a plurality of illumination sources including visible light emitting illumination sources and infrared (IR) emitting illumination sources,
an interior cylindrical reflector including a plurality of curvatures to focus light from the illumination sources in a hemispherical illumination pattern,
an antenna,
a modem connected to the antenna,
a controller connected to the modem and the plurality of illumination sources,
a non-transitory memory storing instructions that, when executed by the controller, cause the controller to
wirelessly pair with a remote controller via the modem,
wirelessly pair with another portable light via the modem,
select one or more illumination sources in response to a user command received from the remote controller via the modem, and
a battery compartment electrically connected to the modem, the controller, and the plurality of illumination sources;
a transparent cover covering the lighting shelf; and
a base attached to the housing.
2. The portable light of claim 1 , wherein the housing further comprises one or more input devices.
3. The portable light of claim 1 , wherein the illumination sources comprise light-emitting diodes (LEDs).
4. The portable light of claim 1 , wherein the plurality of visible light emitting sources emit light in wavelengths corresponding to colors selected from white, yellow, green, red, and blue.
5. The portable light of claim 1 , wherein the plurality of IR light emitting sources emit IR in the 840-940 nm range compatible with night vision devices.
6. The portable light of claim 1 , wherein the memory further stores instructions that, when executed by the controller, cause the controller to cause the selected illumination sources to emit light at an intensity selected from a plurality of available intensities.
7. The portable light of claim 1 , wherein the memory further stores instructions that, when executed by the controller, cause the controller to render the light inoperable.
8. The portable light of claim 1 , wherein the memory further stores instructions that, when executed by the controller, cause the controller to cause the selected illumination sources to emit light in compliance with at least one of NATO STANAG (Standardization Agreement), NAVAIR (Naval Air Systems Command) EAF (Engineering and Acquisition Framework) UFC360 (Unified Facilities Criteria, 360 degrees), UFC-3-260-1, and FAA AC Federal Aviation Administration Advisory Circular) 150/5345-50B.
9. The portable light of claim 1 , wherein the modem is configured to transmit and receive encrypted wireless signals.
10. The portable light of claim 1 , wherein the modem is configured to transmit and receive encrypted wireless signals according to AES (Advanced Encryption Standard) 127-Bit Encryption.
11. The portable light of claim 1 , wherein the memory further stores instructions that, when executed by the controller, cause the controller to cause the selected illumination sources to emit light in one of a selected steady-on mode and a flashing mode.
12. The portable light of claim 1 , further comprising an interior cylindrical reflector including a plurality of curvatures to focus light from the illumination sources in an omnidirectional outwards direction.
13. The portable light of claim 1 , wherein the interior cylindrical reflector focuses a majority of the light from 0 degrees to 15 degrees.
14. The portable light of claim 1 , wherein the base includes a plurality of mounting holes.
15. The portable light of claim 1 , wherein the base and the housing include matching threading adapted to enable exchanging the base with another base.
16. The portable light of claim 1 , wherein the base includes solar panels.
