Abstract: PROBLEM TO BE SOLVED: To manufacture a ceramic arc tube with airtightness and optical transmission improved.
SOLUTION: A method of making a fritless seal in a ceramic arc tube body includes the steps of: (a) inserting a feedthrough made of niobium or a niobium alloy into an opening in the ceramic arc tube body; (b) heating the arc tube body to a first temperature in inert gas to at least partially sinter the arc tube body, the inert gas being selected from a group of argon, neon, krypton, xenon and mixtures thereof; and (c) further sintering the arc tube body by heating to a second temperature higher than the first temperature in a hydrogen atmosphere to form an airtight seal between the feedthrough and the ceramic arc tube body.

Abstract: A fluted feed-through for a discharge lamp includes a fluted ceramic core wi th plural channels and plural individual molybdenum or tungsten wires running i n different ones of the plural channels. The wires are twisted together at the ends of the feed-through. The feed-through is insertable into a capillary tube of a ceramic discharge lamp. The wires of the feed-through have a different thermal coefficient of expansion than the ceramic discharge lamp. The wires are thin enough so that the absolute magnitude of the thermal coefficients of expansion is sufficiently small to prevent seal cracks and leaking.
