Abstract: An LED lighting assembly includes, according to various implementations, mechanisms for protecting the LED lights from voltage or current surges, including hardware that absorbs the strike voltage and hardware that provides a bypass path. The provision of a bypass path in the event of the failure of one or LED lights in an LED string allows the string to be, in effect, “turned off” in order to protect the remaining LED lights, thereby allowing the healthy LED lights to stay lit.

Abstract: A harmonics correction circuit is implemented as an independent device (such as a SiP or ASIC), and includes (1) a first node, (2) a second node, (3) a first current path extending from the first node to the second node, (4) a second current extending from the first node to ground, (5) a third current path extending from the first node to the second node, (6) a sense resistor electrically connected to the second node and to ground, (7) a differential circuit (e.g., a differential amplifier or other type of operational amplifier (“op-amp”)) that has a first input, a second input, and an output, (8) a transistor comprising a gate that is electrically connected to the output of the differential circuit, a drain that is electrically connected to the third current path, and a source that is electrically connected along the third current path.
