Abstract
A metal vapor arc lamp comprises an alumina ceramic arc tube having an end closed by an apertured ceramic plug sealed by sealing frit. A metal lead wire extending through the aperture is also sealed therein by sealing frit and supports an electrode within the arc tube. A cross wire attached to the inlead immediately above the plug forms a wick equalizing the distribution of sealing frit between the plug seal and the inlead seal and also serves as a hanger for supporting the plug and electrode assembly in the arc tube during sealing.
