Abstract
a lighting fixture includes a power input configured to be coupled to a power source, a power output configured to be coupled to an external load and a lighting device, such as a light emitting diode (LED) device, coupled to the power input and configured to provide illumination. The lighting fixture further includes a protection circuit coupled between the power input and the power output and configured to detect a condition of a power source coupled to the power input and to control power transmission between the power input and the power output responsive to the detected condition. The power output may be configured to support daisy-chain connection of the lighting fixture to at least one other lighting fixture, and the protection circuit may be configured to control power transmission to the at least one other lighting fixture responsive to the detected condition.
