摘要

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.

說明書

FIG. 39 illustrates a method of controlling the LED driver systems herein disclosed when a demand response signal is received;

FIG. 40 illustrates a method of controlling the LED driver systems herein disclosed to control and/or power accessories via a bus and/or optional port;

FIG. 41 illustrates a method of controlling the LED driver systems herein disclosed to remotely check the health of emergency backup battery functionality; and

FIG. 42 shows a diagrammatic representation of one embodiment of a computer system within which a set of instructions can execute for causing a device to perform or execute any one or more of the aspects and/or methodologies of the present disclosure.

DETAILED DESCRIPTION

The word “exemplary” is used herein to mean “serving as an example, instance, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

For purposes of this disclosure, a “backup battery” is any battery or other storage device that can be electrically coupled to an LED driver and provide backup LED driving power in the event of a loss of primary power (e.g., AC mains power). Other terms for a backup battery include a ballast or emergency ballast.
