Patent number: 11177687Abstract: This disclosure describes systems, methods, and apparatus for a combined LED driver and emergency backup battery system. The LED driver can include current regulation circuitry as well as a bus enabling charging and discharging of an energy storage device from and to the bus. A master controller can control charging and discharging of the energy storage device via a controller of an energy storage management system, and also communicate with the current regulation circuitry to control a balance of power between an AC mains, the energy storage device, and driving of an LED light source. Accessories may be coupled to the bus and receive low voltage power from the bus and optionally receive commands from the master controller and provide sensed data back to the controller. A wireless network interface to the master controller can enable system states based on electrical power company indications and instructions.Type: GrantFiled: May 8, 2019Date of Patent: November 16, 2021Assignee: LEDVANCE LLCInventors: Anthony Catalano, Steven S.

Patent number: 9326346Abstract: Thermally managing at least one light-emitting diode (LED) receiving an operating current and/or an operating voltage and being operable at an operating temperature includes determining a current thermal operating point of the LED, obtaining a thermal operating range of the LED, and calculating a new operating point of the LED based on the current thermal operating point and the thermal operating range, wherein the new operating point is within the thermal operating range. A control signal is generated that adjusts power delivered to the LED to cause the LED to operate at the new operating point. Detection of the operating temperature of the LED may be based on the magnitude of a current pulse superimposed on the operating current provided to the LED and the magnitude of the voltage pulse across the LED resulting from the applied current pulse superimposed on the operating current.Type: GrantFiled: June 11, 2015Date of Patent: April 26, 2016Assignee: TerraLUX, Inc.Inventors: Anthony W.

Patent number: 8950760Abstract: A mobile and adjustable dolly having an adjustable āVā shaped dolly frame. The dolly frame comprises first and second pivotal frame members rotationally coupled to a central support frame member forming a āVā shape. The central support frame member comprises a series of angle maintaining features for securing each frame member at any of a plurality of angled configurations. A distal caster, having a wheel rotation disposed therewith, is assembled to a distal end of each frame member and a central caster is assembled to a pivotal region of the dolly frame. A vehicle support subassembly is disposed upon and extends upward from the each respective frame member. An elongated handle assembly extends from the central caster. The elongated handle assembly further comprises a wheel chock, which removably engages with the central wheel when subjected to the weight of the elongated handle assembly.Type: GrantFiled: February 14, 2014Date of Patent: February 10, 2015Inventor: Steven S.
