Abstract: A system includes a cabinet having an enclosed cavity having a plurality of reflective interior walls that reflect UV radiation and a plurality of UV-emitting LEDs. The plurality of LEDs are arranged on at least four of the reflective interior walls of the enclosed cavity and configured to direct UV radiation into an interior of the cavity.

Abstract: A modular direct current power distribution network includes a first power distribution block including a first housing, a first main power storage device enclosed within the housing, a first plurality of device connection ports in the housing, and at least one first transistor controlling the connection from the first main power storage device to the first plurality of device connection ports, at least one external device, the at least one external device having a power exchange port electrically connected to a device connection port of the first plurality of device connection ports and an individual power storage device electrically connected to the power exchange port, and a first controller configured to sense a load sharing threshold event matching a load sharing threshold, and to modify the state of the at least one first transistor in response to the load sharing threshold condition.

Abstract: Disclosed is a heat-dissipating light-emitting device, including a light-emitting element, a heat-conducting base plate in physical contact with a heat sink, and a driver circuit. The driver circuit and light-emitting element are electrically coupled to each other and electrically isolated from the base plate. The light-emitting device and heat sink may be included in a light fixture. Also disclosed is a method for assembling the light-emitting device.
