System for directional control of light and associated methods

A lighting device for emitting light in selective directions comprising:

• a first light source structure member having an outer surface;
• a first plurality of light sources attached to the outer surface of the light source structure member;
• a controller functionally coupled to the first plurality of light sources;
• a power supply positioned in electrical communication with at least one of the controller and the first plurality of light sources;
• and
• a first optic having a receiving section comprising a receiving surface, an intermediate section, and a concave arcuate emitting section, the concave arcuate emitting section comprising a plurality of triangular prism shaped facets, and the first optic being carried by the first light source structure member;
• wherein the triangular prism shaped facets are defined by a rectangular shaped lower surface proximal to the receiving section and an opposing rectangular shaped upper surface distal to the receiving section and formed at an angle relative to the lower surface;
• wherein at least two edges of the rectangular shaped lower surface are adjoined by edges of a separate triangular prism shaped facet;
• wherein the rectangular shaped upper surfaces are defined by increasing slopes from the optic center;
• wherein the rectangular shaped upper surfaces are configured so as to define the concavity of the concave arcuate emitting section;
• wherein each light source of the first plurality of light sources is positioned such that light emitted thereby is received by the receiving surface, directed through the intermediate section, and emitted through a triangular prism shaped facet of the plurality of triangular prism shaped facets of the first optic;
• wherein each triangular prism shaped facet of the plurality of triangular prism shaped facets is configured to redirect light in a direction unique from the other triangular prism shaped facets of the plurality of triangular prism shaped facets;
• and
• wherein the controller is configured to selectively operate each light source of the first plurality of light sources.
