Title: The Innovative Contributions of Alexander J Houghton
Introduction
Alexander J Houghton, an accomplished inventor based in Annandale, VA, has made significant strides in the field of vessel navigation lights. With a notable portfolio comprising three patents, Houghton has demonstrated his commitment to enhancing maritime safety through innovative optical solutions.
Latest Patents
Houghton's latest patents focus on advanced optical elements for vessel navigation lights. These innovations provide improved and cost-effective methods for achieving uniform luminous intensity over a sharply defined horizontal arc of visibility, as well as satisfactory vertical visibility. The patents disclose systems for projecting light from diffuse sources or arrays of point sources, offering precisely defined horizontal and vertical arcs. The two geometric configurations presented—symmetrical and asymmetrical compound parabolic concentrators—can be constructed as either reflective cavities or refractive dielectrics. This versatility yields four distinct designs capable of ensuring uniform illumination across various horizontal arcs. Moreover, the patents detail three modes for diffuse light projection, further refining vertical visibility. Importantly, Houghton’s optical elements meet the stringent visibility requirements established by the Final Act of the International Conference on Revision of the International Regulations for Preventing Collisions at Sea, 1972 (72 COLREGS), as well as the International Rules of Navigation Act of 1977, 33 U.S.C. 1601, all while maintaining an emphasis on economy.
