Abstract: A power supply includes a casing including a heat-conducting material and having an inner surface and an outer surface. The casing is a one-piece component having a substantially tubular shape. The power supply also includes a circuit board disposed in the casing. The circuit board has a first surface on which one or more circuit components are mounted and a second surface on an opposing side of the first surface. The power supply also includes a first cover disposed over a first opening at a first end portion of the casing on a tubular axis, and a second cover disposed over a second opening at a second end portion of the casing on the tubular axis. The first surface of the circuit board faces the inner surface of the casing.
