1. A method of illuminating a target area according to a composite beam pattern comprising:
- a. identifying one or more factors related to the target area;
b. developing a plurality of individual beam patterns which, when assembled, approximates the composite beam pattern;
c. developing a lighting system comprising a plurality of lighting fixtures each of which produces an output from a plurality of light sources contained therein and which contributes to at least one individual beam pattern and comprises;
i. said plurality of light sources pivotable about at least one axis;
ii. one or more light directing means associated with said plurality of light sources and contained within said lighting fixture and pivotable about at least one axis;
iii. one or more light redirecting means associated with said plurality of light sources and contained within said lighting fixture to provide a first step of redirection of said output from within the lighting fixture; and
iv. one or more light redirecting means associated with said plurality of light source but not contained within said lighting fixture and pivotable about at least one axis and independently pivotable of said light directing means to provide a second step of redirection of said output from outside the lighting fixture; and
d. installing the lighting system at the target area so to produce the composite beam pattern including first and second light redirecting steps.

Abstract
Presented is a design of modular LED lighting fixture whereby the steps of light directing and light redirecting are independent, but cooperative, so to promote a compact fixture design with low effective projected area (EPA), good thermal properties, and a selectable degree of glare control. A lighting system employing a plurality of said fixtures is highly customizable yet has the potential to be pre-aimed and pre-assembled prior to shipping, which reduces the potential for installation error while preserving the customized nature of the fixtures.

11. A lighting fixture comprising:
-
a. a housing having a first end, a second end, a length of body therebetween, an internal space in the body between the first and second ends, and an opening in the body into the internal space; b. a light transmissive device sealed against the opening in the body; c. one or more light sources mounted within the internal space of the body of the housing nearest the first end and at a predetermined angle relative the light transmissive device, each light source producing a light output; d. one or more reflective devices mounted within the internal space of the body of the housing at a predetermined angle relative the light transmissive device and adapted to redirect the light output of the light sources; e. one or more reflective devices mounted proximate the light transmissive device at the second end of the body outside the internal space and adapted to redirect the light output of the light sources; and f. a pivoting device adapted to pivot the one or more reflective devices mounted at the second end of the body about an axis extending transversely through the body of the fixture and nearer the second end of the fixture than the first end. - View Dependent Claims (12, 13, 14, 15, 16)
