    摘要： A high intensity discharge lamp, in certain embodiments, includes a uniquely shaped shoulder and dimensions selected to reduce stress and associated cracking. The uniquely shaped shoulder has a variable diameter, such as, e.g., a cup-shaped geometry, a curved funnel-shaped geometry, or a conical-shaped geometry. The selected or optimized dimensions may include a tip-to-neck distance, a tip-to-wall distance, and an internal diameter of the lamp. The selected or optimized dimensions also may include a uniform wall thickness, an arc gap distance, and an electrode thickness. These dimensions and shapes are selected to reduce undesirably high maximum stresses and temperatures in the lamp. As a result, the lamp is able to provide higher performance with a longer life due to a decreased risk of stress cracking during rapid start up and steady state operation.

    摘要翻译： 在某些实施例中，高强度放电灯包括唯一成形的肩部和选定的尺寸以减少应力和相关的开裂。 独特形状的肩部具有可变的直径，例如杯形几何形状，弯曲的漏斗状几何形状或锥形几何形状。 所选择的或优化的尺寸可以包括灯头到灯头的距离，灯头到墙壁的距离和灯的内径。 所选择的或优化的尺寸也可以包括均匀的壁厚，电弧间隙距离和电极厚度。 选择这些尺寸和形状以减少灯中不希望有的高的最大应力和温度。 因此，由于在快速启动和稳态操作期间应力开裂的风险降低，灯具能够提供更长的使用寿命。
