Remote Lighting Flood Light with Double Fresnel Light Shaping Luminaire

Because of their restricted placement and imperfect design, existing overhead floodlights create uneven illumination across the flight decks of Air Capable Ships (ACS). To address the U.S. Navy need for improved deck light distribution, Physical Optics Corporation (POC) proposes to develop a new Remote Source Lighting Overhead Flood Light (RESLOF) system, in which the luminaire is switchable between visible light and night vision lighting. In the luminaire, the light is coupled from a xenon lamp to a fiber bundle. The fiber bundle delivers light to a luminaire, which has a nonimaging collimator and special Fresnel structures, which tailor the output, evenly illuminating the flight deck. The RESLOF luminaire, because it is transparent at radar wavelengths, has no radar signature, and it does not require periodic maintenance. In Phase I, POC will develop and test a preliminary RESLOF system to demonstrate the feasibility of the RESLOF approach and produce a design for Phase II implementation that will meet Navy light distribution specifications. In Phase II, an engineering prototype will be developed and tested in a realistic ACS deck illumination scenario.
