    Abstract: A lighting fixture, such as a recessed or can type lighting fixture, has an external housing containing a number of LEDs used to provide light. The LEDs are connected to a power supply, and are mounted on a heat sink that includes heat-dissipating fins that are oriented vertically within a vertical portion of an internal flow tube. The internal flow tube may be U-shaped, with entry and exit points on opposite ends of the flow tube. The external housing and flow tube are oriented so as to create a path for air to rise along the heat sink as it is heated then flow back down along the unheated path of the flow tube. An air mover may also be placed in the flow tube to provide further air flow through the flow tube.

    Abstract: The present invention discloses a cathode for an electron gun comprising a base metal mainly composed of nickel and containing one kind of reducing element at least, a metal layer mainly composed of tungsten, tungsten-nickel, or zirconium-tungsten on the upper side of the base metal, and an electron emitting material layer containing alkaline earth metal oxide including barium at least on the upper side of the metal layer. The metal layer is formed by spreading tungsten, tungsten-nickel, or zirconium-tungsten on the base metal and heating it to have particle smaller than that of the base metal, to increase its life cycle under a high current density load by ensuring a diffusion route of reducing element steadily, used for good generation of free radical barium atom.
