Abstract: A lighting system comprises an excitor which drives at least one reactor. The reactor is an under-damped resonant circuit that includes a network of lighting elements in a reactive string and reactive components distributed among the lighting elements. These reactive components can regulate individual lighting elements. The lighting elements emit an AC luminous waveform which comprises a first phase and a second phase. Selected lighting elements can be modulated by a datastream. The modulated light moves through free-space to a receiving device.

Abstract: A power supply device includes a capacitance partition, a control partition, a power switching partition, a thermal conduction partition, and a magnetic partition. The thermal conduction partition includes electrical connections to connect other partitions. The thermal conduction partition provides for magnetic shielding of the magnetic partition and thermal dissipation in a substantially orthogonal direction to the electrical connections. The layering arrangement allows automated production and/or testing.
