Abstract: An apparatus and method for producing specified output intensity distribution requirements from a single LED source, wherein the apparatus includes a single LED source and a cover, including a lens, that captures and controls the non-collimated light of the LED source and limits its spread vertically and horizontally as well as producing intensity variations within the output pattern. In one aspect of the invention, the lens is on the same order of size as the LED source, the cover has an exposed surface area several times larger than the area of the lens and is primarily configured to have retroreflective properties.

Abstract: A radiant energy redirecting apparatus, method, and system. In one aspect, it comprises two radiant energy distribution surfaces, each surface comprised of a multiplicity of equivalently shaped linear distribution elements, where each surface acts to distribute radiant energy in orthogonal directions, and where each surface is comprised of refractive or total internal reflection elements, or a combination thereof, for the purpose of efficiently directing pseudo-collimated radiant energy into a generally rectangular-shaped output distribution in angle space.

Abstract: An apparatus and method for controlling light from a non-rectangular light source. The apparatus and method relate to using a light guide of a single piece of light-transmissive material having a plurality of external surfaces. One external surface is shaped to collect and substantially collimate light from the light source into the interior of the light guide. At least one external surface is shaped to internally control and direct light such that it issues from the light guide in a substantially rectangular pattern and with substantially total internal reflection. The light guide can be used to create a single controlled beam pattern. In another aspect, one light guide could be adapted to issue two controlled beam patterns. Still further, two light guides could be mounted in a common housing and used to generate two beam patterns. One exemplary application of two beam patterns is a bow light for marine vessels.
