  • Patent number: 10344948
    Abstract: There is a category of situations which may have previously been considered direct replacement but in fact takes on many elements of a true retrofit; namely, replacing existing LED lighting systems (which they themselves were retrofits) with different LED lighting systems that (i) overcome a deficiency or inadequacy of the existing LED lighting system retrofit, (ii) adds a functionality to the existing LED lighting system retrofit, or (iii) reestablishes functionality that would otherwise be lost with the existing LED lighting system retrofit. Discussed herein are means to provide improved glare control, horizontal beam containment, playability and control functionality for interfacing with third party controls in these so-called retrofit-of-a-retrofit, or “upgrade” situations.

  • Patent number: 10337693
    Abstract: 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.

  • Publication number: 20170006677
    Abstract: The present invention generally relates to the field of large area lighting, such as lighting for sport venues. More specifically, some embodiments of the present invention relate to controlling solid state illumination for various applications including sports lighting, architectural lighting, security lighting, parking, general area, interior, larger area and others. Embodiments according to aspects of the current invention monitor lighting circuits with regard to voltage and current, compare readings with stored models, characterize lighting circuits with regard to stored models for voltage and current, and control lighting circuits in accordance with desirable outcomes.

  • Patent number: 8537021
    Abstract: Apparatus, methods, and systems for providing comprehensive control and monitoring of an electrical system are presented. The envisioned invention according to at least one aspect provides for control and monitoring functions that include main circuit level functions and sub-circuit level functions. The control and monitoring function further provides for communication with a remote central control center to send commands to and receive data from the main circuit control and/or sub-circuit(s). Information from the monitoring function may be used to alter the operation of the system, aid in diagnostic response, and ultimately, improve the safety and reliability of the electrical system.
