Abstract: Tips for electrodes that are adapted to be applied to a ceramic halide lamp are formed by backwinding tungsten wire into a coil onto a tungsten shank. The outer diameter of the coil of tungsten wire is maintained sufficiently small so that the electrode tips can be inserted through openings in the legs of the electric arc tube of the ceramic halide lamp and the tungsten coil positioned within the hollow interior of the electric arc tube.

Abstract: Discharge tubes for a lamp include a body portion with a first end, a second end, and a tubular member defining an interior area. The tubular member extends along an elongated axis between the first end and the second end. The discharge tube includes a first end portion provided at the first end of the body portion. The first end portion includes a first tapered portion that is tapered in a direction extending substantially perpendicular from the elongated axis. The first tapered portion includes an interior surface facing the interior area. The tapered portion spans between a maximum extent in the direction of the elongated axis and a minimum extent in the direction of the elongated axis.

Abstract: A metal halide high intensity discharge lamp having an arc tube assembly including a pair of discharge electrodes and a pair of starting electrodes. Each starting electrode is adjacent a respective discharge electrode. During starting, the lamp makes the glow discharge to arc discharge transition in a substantially shorter time than a lamp with a single starting electrode, and exhibits a substantially improved lumen maintenance.
