A significant reduction in thermal energy loss along the legs or ends of the arctubes in a CMH lamp is achieved in the present invention. The diameter of a mandrel ( ) is significantly reduced for CMH lamps. Either a single overwind ( ) or multiple overwind layers ( ) are used. Since the thermal conductivity of the mandrel greatly exceeds that of the overwind, the axial thermal conductivity will scale like the cross sectional area of the mandrel alone.

A discharge lamp including an arc tube having an elongated body enclosing a discharge chamber. The discharge chamber receiving first and second electrodes therein for forming an arc discharge in the discharge chamber. The lamp also including an outer envelope having an envelope cavity therein. A support member is received in the envelope cavity for supporting the arc tube. A containment member extends from the support member and is received around at least a portion of the elongated body of the arc tube. Additionally, a method of manufacturing a discharge lamp is disclosed.

Arc chambers for discharge lamps, such as ceramic metal halide lamps, have ends, where the electrodes for the arc chambers are introduced, that are configured such that, when the arc chambers are arranged vertically, the metal halide additives in the arc chambers will accumulate substantially only on the inner surfaces of the ends, which can have closure walls that are thicker than the thickness of the walls of the body portions of the arc chambers. The ends can be further configured such that the metal halides are deposited substantially uniformly in a thin layer over the ends of the arc chambers. The ends can also be configured in a manner that no sharp edges are provided at the ends of the arc chambers so that corrosive effects to the arc chamber resulting from localized temperature variations are minimized.

A lamp includes a discharge sustaining fill which includes cesium halide, one of indium halide and thallium halide, optionally gadolinium halide and a rare earth halide component selected from dysprosium halide, holmium halide, thulium halide, and neodymium halide. In operation without a jacket, the lamp may have a color temperature of from 7,000K to 14,000K and a color rendering index of at least 70 when operated at an arc wall loading in excess of about 2 W/mm.

An electrode assembly for a discharge lamp, particularly a ceramic metal halide (CMH) lamp, having a ceramic body defining a discharge chamber and at least one leg having an opening therethrough. An electrode assembly is received at least in part in the body, preferably including a niobium mandrel, a molybdenum mandrel, and a molybdenum overwind received over the mandrel. A tungsten portion is then joined to the molybdenum composite. Adjacent turns of the overwind are spaced by a gap to facilitate receipt of an associated seal material on the overwind and the molybdenum mandrel. The gap is approximately 10% to 50% of the dimension between adjacent turns of the overwind relative to a diameter of the overwind.
