Apparatus, method, and system for a multi-part visoring and optic system for enhanced beam control
First Claim
1. A lighting fixture for precision lighting comprising:
- a. a housing comprising;
i. an interior space;
ii. an opening;
iii. a light transmissive material over the opening to at least substantially seal the interior space;
b. internal light control in the interior space of the housing comprising;
i. an array of densely packed LED light sources mounted on an LED mounting substrate having a substantially planar surface;
ii. an optic on each LED light source to produce a preliminary light output beam pattern from individual light source output beam patterns wherein the optic comprises;
1. an emitting face formed from a substantially thin sheet of optical quality silicone-based material; and
2. a holder to removably clamp and closely position the sheet over a subset of the LED light sources;
iii. an internal visor at or near at least some of the LED light sources to selectively redirect a portion of the preliminary light output beam patterns;
iv. so that a composite light output is directed out of the opening and light transmissive material of the housing from the plurality of individual redirected LED light sources outputs;
c. external light control on the housing outside the interior space comprising;
i. an external visor at or near the opening having;
1. at least a first surface that is extendable at least partially into the composite light output from the housing and has selectable;
a. reflectivity to control incident light from the composite light output;
b. pivotability relative to the housing to selectively adjust cutoff of the composite light output from the housing;
2. at least a second surface outside the composite light output from the housing; and
d. an adjustable armature to selectively aim the housing in space so to collectively provide precision lighting.

Abstract
Precision lighting design is a subcategory of lighting design which benefits from a concerted, synergistic effort to improve beam control; sports lighting is one such example. Beam control is improved when all light directing and redirecting devices are considered together, and insomuch that adverse lighting effects are best avoided when considering how all the lighting fixtures in an array interact with one another. To that end, envisioned is a multi-part visoring (i.e., light redirecting) and optic (i.e., light directing) system designed with consideration towards how a fixture lives in a mounted space—how its photometric and physical presence affects other fixtures in or proximate said space—while demonstrating improved beam control over that which is available to general purpose (e.g., indoor residential) lighting.

11. A method of illuminating a target area or space with precision lighting fixtures comprising:
-
a. elevating a plurality of aimed arrays of lighting fixtures on support structures at different locations relative to the target area or space, each lighting fixture comprising a plurality of densely packed LED light sources sealed in a housing with a light transmissive material; b. controlling light and glare at each lighting fixture for a given location and elevation and aiming direction of each lighting fixture relative to the target area of space by; i. producing preliminary light output beam patterns from each LED light source by positioning an optic relative the LED light sources; ii. selectively redirecting a portion of the preliminary light output beam patterns within the sealed housing by positioning a visor in the housing relative to the LED light sources to produce a composite light output which is directed out of the light transmissive material of the housing; iii. selectively redirecting a portion of the composite light output outside the sealed housing with a first stationary surface of an external visor; and iv. selectively cutting off the composite light output outside the sealed housing with a first pivotable surface of the external visor that at least partially extends into a portion of composite light output. - View Dependent Claims (12, 13, 14, 15, 16)
