摘要： An improved metal-halide arc discharge lamp includes an arc tube having a substantially cylindrical body surrounded laterally by a substantially cylindrical heat-conserving sleeve within an evacuated outer envelope. The ratio of the outer radius of the arc tube divided by the inner radius of the sleeve falls within an optimum range of approximately 0.54 to approximately 0.68, and preferably within a range of approximately 0.60 to approximately 0.63. A lamp constructed in accordance with the invention exhibits improved luminous efficacy and color rendering in comparison to prior art counterparts. The improved performance is believed to be attributable to the more nearly isothermal operation of the arc tube for a given wall loading.
摘要翻译：改进的金属卤化物电弧放电灯包括具有基本上圆柱形的主体的电弧管，所述圆筒体由抽空的外封套内的大致圆筒形的保温套筒横向包围。电弧管的外径除以套筒的内半径的比率落在约0.54至约0.68的最佳范围内，优选在约0.60至约0.63的范围内。与现有技术相比，根据本发明构造的灯显示出改进的发光效率和显色性。据信，改进的性能可归因于给定壁装载的电弧管的近等温操作。

摘要： An arc tube for horizontal operation and arc discharge lamp employing same wherein the arc tube has devices in each end for suppressing crystalline deposit penetration into the arc tube press seals along the shanks of the main electrodes. Experimental evidence shows that crystalline penetration into a press seal weakens the press seal and is the likely cause of an occasional arc tube burst during lamp operation, a problem well known in the art. In a preferred embodiment, a starting electrode is mounted above the main electrode in each end of the operationally positioned arc tube. So placed, each starting electrode is upstream in the convective flow of the gaseous fill within the arc tube. Each starting electrode may be electrically coupled with the lamp's circuit or electrically isolated therefrom without substantially affecting the starting electrode's ability to suppress crystalline penetration of the press seal about the base of the adjacent main electrode. In a lamp in accordance with the invention, the probability of an arc tube burst during lamp operation has been substantially reduced and, consequently, the need for employment of protective measures or containment devices has been substantially reduced.
摘要翻译：用于水平操作的电弧管和使用其的电弧放电灯，其中电弧管在每个端部具有用于抑制结晶沉积物渗透到电弧管中的装置，沿着主电极的柄压紧密封。实验证据表明，结晶渗透到压力密封件中减弱了压力密封，并且是灯操作期间偶尔的电弧管爆裂的可能原因，这是本领域公知的问题。在优选实施例中，在操作定位的电弧管的每个端部中，在主电极上方安装起始电极。如此放置，每个起始电极在电弧管内的气态填充物的对流中是上游的。每个起始电极可以与灯的电路电耦合或与其电隔离，而基本上不影响起始电极抑制压密封围绕相邻主电极的基部的晶体渗透的能力。在根据本发明的灯中，在灯操作期间电弧管爆裂的可能性已经大大降低，因此，使用保护措施或容纳装置的需要已经大大减少。
