Abstract
A lighting fixture is presented comprising a plurality of modular apparatuses wherein each modular apparatus comprises one or more light sources and one or more light directing or light redirecting devices. 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.
Claims19
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.
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.
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.
