FIG. 17 illustrates another embodiment of an integrated dimming LED driver and battery backup system between an AC mains and a set of one or more LED lights. FIG. 17 illustrates how the bus 1760 may include a data channel (dashed) and a power channel (solid), where either or both channels can carry one or more signals. For instance, the power channel can include a high and low voltage signal (e.g., via separate physical lines).
FIG. 18 illustrates another embodiment of an integrated dimming LED driver and battery backup system between an AC mains and a set of one or more LED lights. In this illustration, each of the voltage regulator circuit 1807, the voltage to current converter 1816, and the energy storage management system 1810 can have direct communication or data channels between each of these three components. This is another way to implement a bus 1860. Compare this with FIG. 19, where the communication or data channels pass through the voltage to current converter 1916. For instance, an instruction from the master controller 1990, if arranged in the voltage regulator circuit 1990, passes along the bus 1960 and through the voltage to current converter 1916 to reach the energy storage management system 1910.
