HIGH INTENSITY DISCHARGE ARC TUBE AND ASSOCIATED LAMP ASSEMBLY
摘要
<p>The discharge light source includes an arc tube with a discharge chamber having a predetermined location for a metal halide dose or salt pool that minimizes the impact on the light emitted from the light source. The discharge chamber is preferably asymmetric about a second axis that is perpendicular to a longitudinal axis. In one embodiment, the discharge chamber preferably includes first and second generally spheroidal portions of different diameters spaced along the longitudinal axis. The arc tube has different wall thicknesses in yet another arrangement. In a further exemplary embodiment, a portion of a wall that forms the discharge chamber includes a generally concave surface. These features may be used individually or in combination.</p>
