Methods of adjusting one or more components of said lighting fixture about one, two, or three axes are presented whereby the lighting needs of a target area—even one of complex shape—may be addressed and in a manner that promotes compact fixture design with low effective projected area (EPA) without sacrificing transmission efficiency of the light sources. ## Claims ### Claim 1 A method of illuminating a target area with a composite beam pattern comprising: a. defining one or more mounting locations for one or more lighting fixtures relative the target area, each lighting fixture producing an initial beam output from one or more lighting modules mounted thereto; b. allocating one or more portions of the composite beam pattern to each of said lighting modules; and c. modifying the initial beam output of one or more lighting fixtures so to illuminate its allocated portion of the composite beam, wherein the modification comprises: i. adjusting the lighting fixture or at least one lighting module of a lighting fixture relative its mounting location; and ii. adjusting a portion of the lighting module relative to and independently of another portion of the lighting module; d. such that each initial beam output and modified initial beam output of each lighting fixture collectively produce the composite beam pattern. ### Claim 2 (depends on 1) The method of claim 1 wherein the adjusting the lighting fixture or at least one lighting module of a lighting fixture elative its mounting location comprises pivoting about a first pivot axis, and wherein the adjusting a portion of the lighting module relative to and independently of another portion of the lighting module comprises pivoting about a second axis, and wherein the first and second pivot axes are orthogonal. ### Claim 3 (depends on 1) The method of claim 1 wherein the adjusting the at least one module of a lighting fixture relative its mounting location comprises (i) pivoting the lighting module about its mounting location in a first plane and (ii) pivoting the lighting module relative its mounting location in a second plane. ### Claim 4 (depends on 1) The method of claim 1 wherein each lighting module comprises light directing means and light redirecting means, and wherein the adjusting a portion of the lighting module relative to and independently of another portion of the lighting module comprises pivoting the light redirecting means relative the light directing means. ### Claim 5 (depends on 1) The method of claim 1 wherein the independent adjusting a portion of the lighting module relative to another portion of the lighting module comprises pivoting and releasably fixing in position over a range of positions a. set of solid state light sources and independently pivoting and releasably fixing in position over a range of positions a visor for the said set of solid state light sources. ### Claim 6 (depends on 5) The method of claim 5 wherein the set of solid state light sources comprises a linear array. ### Claim 7 (depends on 6) The method of claim 6 wherein the visor comprises a reflective surface substantially parallel to the linear array of light sources. ### Claim 8 (depends on 7) The method of claim 7 wherein the linear array of light sources and the visor pivot around substantially the same axis. ### Claim 9 (depends on 8) The method of claim 8 wherein the module comprises an exterior that is aerodynamic. ### Claim 10 A method of illuminating a target area according to a pre-defined composite beam pattern comprising: a, identifying one or more factors related to a lighting plan for the target area; b. developing a plurality of individual beam patterns which, when assembled, approximates the pre-defined composite beam pattern; c. developing a lighting system comprising a plurality of lighting modular assemblies each of which produces an output which contributes to at least one individual beam pattern and comprises: i. one or more light directing components including plural light sources pivotable about at least one axis; ii. one or more light redirecting components pivotable about at least one axis and independently pivotable relative at least one axis of said light directing components; and d. installing the lighting system at the target area so to produce the composite beam pattern. ### Claim 11 (depends on 10) The method of claim 10 wherein the one or more factors related to a lighting plan for the target area comprises all of: a. size of the target area; b. shape of the target area; c. number and layout of one or more elevating structures to which said one or more lighting modular assemblies are affixed; d. wind loading conditions; e. light level; f. lighting uniformity; and g. color of light. ### Claim 12 (depends on 10) The method of claim 10 wherein said light directing means comprises one or more of: a. a lens; and b. a filter. ### Claim 13 (depends on 10) The method of claim 10 Wherein said light redirecting means comprises one or more of: a. a reflective device; b. a diffuser; and c. light absorbing device. ### Claim 14 A lighting module comprising: a. an enclosure comprising a body having a length and an interior and an opening into said interior wherein the body is pivotable about a first pivot axis extending along the length of the body, the enclosure adapted to receive and positionally affix one or more light sources in its interior such that the one or more light sources project light generally along a first principal axis; b. a structural component pivotably affixed to the enclosure and adapted to receive a reflective surface; c. wherein the structural component is independently pivotable from the body along the first pivot axis. ### Claim 15 (depends on 14) The lighting module of claim 14 further comprising a light transmissive material adapted to seal against the opening of the body of the enclosure. ### Claim 16 (depends on 14) The lighting module of claim 14 wherein the structural component is further adapted to receive a light diffusive member. ### Claim 17 (depends on 14) The lighting module of claim 14 wherein the structural component is adapted to receive plural reflective surfaces. ### Claim 18 (depends on 17) The lighting module of claim 17 wherein plural reflective surfaces includes one or more rails having at least one reflective surface and extending more along the first principal axis of the light sources than transverse to it. ### Claim 19 (depends on 14) The lighting fixture module of claim 14 comprising an exterior that is aerodynamic.
