Abstract
Systems, methods, and devices for providing a luminaire inductively coupled to a power transmission line include a current transformer containing a plurality of tap points, and a plurality of tap switches that can be coupled to the tap points. The plurality of tap switches are connected to a microcontroller. Further, the systems, methods, and devices include an energy storage device, and LED light source(s). In some instances the current transformer powers the LED light source(s), and in other instances, the current transformer charges the energy storage device and the energy storage device in turn powers the LED light source(s), and in yet other instances, a combination of powering directly from the current transformer or energy storage device may be switched back and forth depending on a variety of parameters.
