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

The system 3002 or the optional port 3050 can include at least three I/Os: a high voltage I/O 3046 (e.g., 5-50V), a low voltage I/O 3048 (e.g., 5V), and a data I/O 3052. These three I/Os can be part of the bus 3060. While the optional port 3050 is here shown with three channels, the optional port 3050 and the corresponding bus 3060 can also have two channels. However, these channels can be implemented with any number of physical arrangement of leads, wires, or electrical connections. For instance, a power channel and a data channel could be implemented on a single physical lead where the data was superimposed on the power signal. At the same time, a second physical lead may be needed to conduct the ground signal for the power lead. Alternatively, a power channel can be implemented as one, two, three, or more physical leads each carrying one or more different voltages (e.g., one carrying high and one carrying low voltage).

FIG. 33 illustrates one exemplary embodiment of the bus and energy storage management system. In this example, the bus comprises six channels: low voltage (e.g., 5V), high voltage (e.g., 5V-50V), data, interrupt, clock, and ground. The optional port 3350 provides an interface between the system 3302 and regions of the bus external to the system 3302. However, in other embodiments, the port 3350 may not be needed, where the energy storage management system 3310 is part of the system 3302. The energy storage management system 3310 may include I/Os for the bus to continue on to an accessory 3314 (e.g., a WiFi access point, an environmental sensor, etc.).
