摘要:
Disclosed herein are apparatus, methods, and systems for deriving composite beams from a plurality of light sources such as LEDs. Optical units comprising a plurality of light sources, each source having an associated optic which is individually positionable, 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, methods, and systems of lighting herein make it possible to widely vary the types of beams from an available fixture using a small number of optics and fixtures. In some cases, by using a combination of individual beam patterns from the same or different types of light sources, a small set of individual optics may 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.

An apparatus, method, or system of lighting units comprising a plurality of lighting elements, such as one or more LEDs, each element having an associated optic which is individually positionable. 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.

Apparatus, methods, and systems for a novel approach to on-site evaluation and demonstration of illumination schemes to fit the unique needs of a defined area or object. The system provides a versatile method of producing a wide range of illumination schemes from a limited number of components and allows for optional add-on features or replaceable modules to simulate various lighting characteristics from various types of lighting fixtures, including commercially available fixtures or custom fixtures. Methods of wireless control described herein help to achieve the purpose of the mobile lighting evaluation system in that a system operator may evaluate and/or demonstrate illumination schemes from a convenient remote location.

The invention is directed to a method, apparatus, and system of illuminating a target area and space by providing continuous substantially controlled, concentrated, and aimed light downwardly towards the target area from an elevated position and providing temporary uplight relative to the target area upon a triggering event or condition. The triggering event or condition can be automatically sensed or manually initiated. Examples of automatic sensing include but are not limited to evaluating a sound, an image, or movement of an object. The uplight can be supplied by solid state light sources driven at or above rated operating power for a limited periods of time (e.g. 5-10 seconds for a triggering event in a baseball or football game), to save energy as compared to operating them continuously.

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.
