Systems, methods, and devices for providing a luminaire inductively coupled to a power transmission line

摘要

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.

主权项

1. An outdoor luminaire comprising:
a housing that is mechanically coupled to a power transmission line; at least one light source coupled to the housing; a current transformer to inductively couple the at least one light source to the power transmission line and comprising at least one tap point; and at least one tap switch coupled to the at least one tap point and controlled by a microcontroller, wherein the at least one light source is dimmed based at least in part on a selective engagement of the at least one tap switch by the microcontroller.
