20120217897 | COMPACT AND ADJUSTABLE LED LIGHTING APPARATUS, AND METHOD AND SYSTEM FOR OPERATING SUCH LONG-TERM - A lighting system is provided whereby long operating life can be reasonably ensured by taking into account requirements of the application, characteristics of the LEDs, characteristics of the fixture containing said LEDs, the desired number of operating hours, and—via developed relationships—taking an iterative approach to supplying power to the LEDs. Through the envisioned compensation methodology and effective luminaire design, a relatively constant light level can be assured for a predetermined number of operating hours (possibly longer); this is true even if operating conditions change, known behavior of LEDs proves untrue over untested period of time, or some other condition occurs which would otherwise cause end-of-life prematurely and prevent the system from meeting the desired number of operating hours. | 08-30-2012 |
20120307486 | APPARATUS, METHOD, AND SYSTEM FOR INDEPENDENT AIMING AND CUTOFF STEPS IN ILLUMINATING A TARGET AREA - 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. | 12-06-2012 |
20130250556 | APPARATUS, METHOD, AND SYSTEM FOR INDEPENDENT AIMING AND CUTOFF STEPS IN ILLUMINATING A TARGET AREA - 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. | 09-26-2013 |
20140092593 | APPARATUS, METHOD, AND SYSTEM FOR REDUCING THE EFFECTIVE PROJECTED AREA (EPA) OF AN ELEVATED LIGHTING FIXTURE WITHOUT THE USE OF AN EXTERNAL VISOR - A design of lighting fixture is presented whereby the outer glass lens—flat in prior art lighting fixtures—is bowed outward. The design of lighting fixture permits a plurality of LED modules to be contained therein, each with their own visor, without constraining the aiming angle of each due to interference between the outer lens and each individual visor. In this manner, an external visor may be omitted thereby obviating undesirable lighting effects such as uneven lighting while still maintaining a reduced effective projected area (EPA) as compared to prior art lighting fixtures with no external visor and a flat outer glass lens. | 04-03-2014 |
