Abstract
Within harsh environment areas, Naval vessels require illumination. Incandescent based Symbol 48.2 explosion-proof fixtures are rated to operate in these spaces but are inefficient, resulting in unsafe fixture surface temperatures and unnecessarily high energy consumption. Under such extreme operating conditions, the lamps in the fixtures fail frequently, leading to high maintenance costs. Producing and qualifying lower wattage, cooler operating and longer lasting explosion-proof fixtures will dramatically reduce maintenance costs and electrical usage. Starting with the proven line of Energy Focus SSL shipboard lighting systems, we propose to develop the necessary architecture, design and construction criteria to build prototype Symbol 48.2 type explosion-proof fixtures. This will be done using advanced thermal modeling, unique SSL protection strategies, and with a robust custom driver architecture. Functioning explosion-proof SSL fixtures will be constructed, tested and have their lighting and life performance evaluated. Final engineering optimization will take place in preparation for manufacturing the field-test units.
