Abstract: The disclosure has described a sub-miniature arc lamp and a method to make a sub-miniature arc lamp. An embodiment of the sub-miniature arc lamp includes a sapphire body having a first end and a second end, the first end being coupled to a first cap and the second end being coupled to a second cap to define a sealed envelope, wherein a first electrode being mounted in the first cap and a second electrode being mounted in the second cap are enclosed within the envelope. Other embodiments are described and claimed.

Abstract: A method and an apparatus for cooling an arc lamp have been disclosed. In one embodiment, the arc lamp assembly includes an arc lamp, a first heat sink coupled to an anode of the arc lamp, and a thermally conductive ring surrounding a first part of the outer surface of a reflector body of the arc lamp to thermally couple the reflector body to the first heat sink. Other embodiments have been described and claimed.

Abstract: An arc lamp with a filter mounted internally has been disclosed. The arc lamp includes an anode, a cathode, a body defining a cavity, wherein the anode and the cathode are inside the cavity, and a filter mounted within the cavity. Other embodiments are claimed and described.

Abstract: A low profile module and frame assembly for arc lamps has been disclosed. In one embodiment, the arc lamp assembly includes an arc lamp, a first cooling fan coupled to a back of the arc lamp closer to a first side of the arc lamp, and a second cooling fan coupled laterally to the first cooling fan and to the back of the arc lamp closer to a second side of the arc lamp, the first side being opposite to the second side. Other embodiments have been described and claimed.

Abstract: An arc lamp having window flange with slots has been disclosed. The arc lamp may include a reflector body having a circular rim at one end to define an opening, the circular rim having an outer diameter and an inner diameter and a window flange including a surface having a first end and a second end, the first end defining a circle having a diameter larger than the inner diameter of the circular rim of the reflector body, and the surface being brazed to the circular rim along at least a portion of the first end, wherein the window flange further includes a second surface extending from the first end of the first surface to define a plurality of slots. The arc lamp may further include a window mounted to the window flange near the second end of the window flange.
