摘要:
Lighting applications which are particularly difficult to light because of “non-standard” target area characteristics or the like would benefit from advancements in lighting design. That being said, conventional wisdom in lighting design has reached a point of diminishing returns in terms of beam control. Envisioned is an LED lighting system designed for precision lighting insomuch that—as compared to state-of-the-art LED lighting fixtures—sharpness of cutoff is improved while in at least some cases simultaneously allowing a steeper cutoff without undesirable beam shift. Furthermore, overall beam dimensions can be tailored fixture-to-fixture for an application without replacing an entire optic system or designing an entirely new fixture, and control of intensity distribution is improved (e.g., by avoiding striations at the edge of beam patterns). Said envisioned LED lighting system employs a number of materials not used in conventional LED lighting systems in novel ways to achieve the aforementioned.

As lighting systems age the need for retrofits—namely where newer lighting technology is used to replace older or different technology, but where a direct replacement is not possible without some kind of modification to the rest of the lighting system—increases. The residential lighting retrofit market is well established with a one-for-one light source replacement approach that is widely embraced; for example, a table lamp with a failed incandescent bulb can be readily replaced with an LED bulb despite the disparate power requirements because of the onboard driver system, and this avoids having to modify the lamp itself, the outlet, incoming power, etc. No such solution exists for specialized lighting systems such as sports and wide area lighting systems. The present invention is directed to such a solution, and one which is cost effective, easy to implement, and customizable to meet the varying site requirements of such specialized systems.
摘要:
Apparatus, method, and system for improving visibility of objects against a background. Background luminance is monitored for an event or condition. Upon sensing of the event or condition, uplighting is provided for one or more areas above a target area at a time and in a manner which increases visibility of the object against the background. In one example, the objects are sports balls and the background is sky, stadium, or sports field. Time and manner can include detection of an event indicative of a ball being in play or transition between daylight and nighttime, manner can include amount, color, or direction of up light.
摘要:
An apparatus, method and system for controlling one or multiple lighting sources such as those powered by driver circuits or voltage splitting methods, to provide an alternative current path around a failed lighting source when one or more individual lighting sources fail.
摘要:
An apparatus, system, and method for solid state lighting is envisioned which, according to aspects of the invention, provides primary event and/or utility lighting during normal power conditions, and which, during periods of interrupted power, provides uninterrupted event lighting for a desired duration, provides a gradual transition from event lighting levels to utility lighting levels, and provides a gradual transition from utility lighting levels to emergency lighting levels.
摘要:
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.
摘要:
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.
