| 摘要 |
An apparatus, method, or system of lighting units comprising a plurality of individually positionable lighting elements, such as one or more LEDs, each element optionally having an associated optic. In embodiments of the present invention, one or more optics are developed using optimization techniques that allow for lighting different target areas in an effective manner by rotating or otherwise positioning the reflectors, refractive lenses, TIR lenses, or other lens types to create a composite beam. The apparatus, method, or system of lighting herein makes it possible to widely vary the types of beams from an available fixture using a small number of inventoried optics and fixtures. In some cases, by using a combination of individual beam patterns, a small set of individual optics would be sufficient to create a majority of the typical and specialized composite beams needed to meet the needs of most lighting projects and target areas. |
