Glare control, horizontal beam containment, and controls in cost-effective LED lighting system retrofits and other applications

A retrofit lighting fixture with improved glare control and horizontal beam containment having a plurality of light sources in a housing, one or more reflective devices to provide said glare control, and one or more light absorbing devices to provide said horizontal beam containment made by a process comprising:

• a. defining a footprint, baseline glare level, and beam spread of an existing lighting fixture having a plurality of light sources in a housing and a visor;
• b. installing said one or more reflective devices on the visor of the existing lighting fixture to eliminate direct viewing of the plurality of light sources and reduce glare over the baseline glare level;
• and
• c. installing said one or more light absorbing devices on the visor or lighting fixture housing of the existing lighting fixture without exceeding said footprint to improve horizontal containment by restricting beam spread in a horizontal plane.

A lighting system having improved glare control and horizontal beam containment or control functionality comprising:

• a. a plurality of light sources;
• b. a plurality of lighting fixture housings each of which contains a subset of the plurality of light sources and an emitting face though which a composite beam from said subsets is emitted towards a target area;
• c. a plurality of visors each of which is attached to a lighting fixture housing;
• d. an elevating structure;
• e. a plurality of armatures adjustable in both horizontal and vertical planes each of which affix a lighting fixture housing to the elevating structure such that the lighting fixture housing and associated visor define a lighting fixture footprint when adjusted in the horizontal and vertical planes;
• f. a reflective device installed on said visor at a position such that direct viewing of the light sources through the emitting face is eliminated at one or more sight lines at the target area;
• g. one or more light absorbing devices installed on said visor or lighting fixture housing at a position to absorb light from the plurality of light sources and cut off the composite beam at a horizontal angle;
• h. a controller adapted to provide a communication upon a user input;
• i. a control device in communication with the controller and adapted to modify an input or output of the plurality of light sources upon a control command;
• and
• j. a communication device in communication with the controller and control device adapted to translate the communication from the controller into the control command for the control device.
