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(shuō)明書(shū)

The energy storage device 3108 can include any number of different devices, such as a battery, capacitor, fuel cell, etc. The energy storage device 3108 may include a circuit or indicator (e.g., barcode, flashing LED, etc.) that provides an indication of the energy storage device 3108 type and identification to the energy storage management system 3110. In other instances, the energy storage management system 3110 can determine a type and identify of the energy storage device 3108 via electrical characteristics of the energy storage device 3108 once coupled to the energy storage management system 3110. The controller 3174, 3274 may be programmed or hardwired to control the converters 3170, 3172, 3176 in different charge and discharge modes depending on the type and identification of the energy storage device 3108. The polarity of the energy storage device 3108 is shown as providing a positive voltage to the step down converter 3170 in FIG. 31, however, it could also be oriented to provide a positive voltage to the step up converter 3172, or the coupling to the converters 3170, 3172 could be electronically or mechanically selectable such that the polarity of the energy storage device 3108 relative to the converters 3170 and 3172 is selectable.
