Infrared illumination beacons emit a covert signal that is visible at long ranges by night vision equipment. These beacons are used for a variety of purposes including identification of landing zones, roadways, obstructions, aircraft, vehicles, and personnel.
However, beacons experience problems with respect to power management, and use large batteries in order to achieve an effective lifespan. This makes them heavy and harder to deploy in the field. Certain models are powered by smaller batteries which compromise the beam strength and limit usefulness.
Navy researchers have developed a ruggedized, waterproof, illumination beacon designed for field deployment with improved power management. The power management system includes a boost/buck converter to produce an output voltage magnitudes larger than an input voltage. The beacon emits a signal that is visible at long ranges and can operate over an extended period of time.
- Light is projected above and below the beacon
- The control unit provides for several flashing modes and can generate UV, visible and IR light
- Compact – the diameter of the beacon is approximately one inch and has a height of 1/2 inch
- System is powered by a coin cell Li-ion battery easily replaceable or rechargeable when depleted
- Technology Readiness Level: 8 Prototype testing validated range of parts
- US patent 8,531,114 available for license
