Patent number: 11337286Abstract: Techniques are described for a lighting system in which light sources are controllable using signals sent over a wireless mesh network. During a commissioning process, a user interface (UI) may present a representation of nodes (e.g., light sources, sensors, controllers, etc.) that are broadcasting a wireless advertising signal. In response to a selection of a particular node, a wireless message may be sent to instruct the selected node to provide a visual indication of its presence, such as a flashing light. The visual indication may enable a user to discern the physical location of the node, such that each node may be added to the mesh network and, in some instances, to a group of nodes. The UI may also enable the definition of scenes, where each scene describes the brightness level or other operating characteristics of particular light source(s) and/or group(s) of light sources when the scene is active.Type: GrantFiled: August 21, 2020Date of Patent: May 17, 2022Assignee: iLumisys, Inc.Inventors: James M. Amrine, Daniel J. Hollenkamp, John Ivey, Francis Palazzolo, Scott Rundell, James R. Scapa

Patent number: 7712918Abstract: A fluorescent light tube retrofit with light emitting diodes (LEDs) that evenly distribute light to avoid bright spots is disclosed. One tube in the form of a conventional fluorescent tube includes two LEDs mounted to the tube on opposite sides of a single circumference of the tube. The LEDs can face the center of the tube, or the LEDs can be offset facing relative to the center of the tube. A reflecting surface can be disposed inside the tube to reflect light evenly toward an arc of the tube. Alternatively, at least one LED can be oriented to direct light into a light pipe that curves around the interior of the tube.Type: GrantFiled: December 21, 2007Date of Patent: May 11, 2010Assignee: Altair Engineering , Inc.Inventors: Dennis Siemiet, John Ivey, Francis Palazzolo
