Abstract: A direct-current short-arc xenon lamp is mounted in prefocused relationship with either a parabolic or an ellipsoidal reflector so that the optical axis of the reflector is aligned with the longitudinal axis of the lamp. The spacing between the lamp electrodes is smaller than that used heretofore and the focal point of the reflector is located at a predetermined position along the arc path. The lamp is rated and operated at a predetermined current within a range of from 70 to 200 amperes and the electrodes are spaced from 4.6 to 7.0 millimeters apart, depending upon the particular operating-current rating of the lamp. When the lamp is operated in a horizontal position, a magnet located adjacent the lamp and outside of the reflector is used to prevent upward bowing of the arc. In the case of a movie projection system, the shorter and more intense arc increases the screen lumens and decreases the power (watts) consumed by the lamp.

Abstract translation: 直流短弧氙气灯以抛物线或椭球反射器以预聚焦的关系安装，使得反射器的光轴与灯的纵向轴线对准。 灯电极之间的间隔小于迄今使用的间隔，并且反射器的焦点位于沿着弧形路径的预定位置。 灯的额定和工作在70至200安培的范围内的预定电流，并且电极间隔4.6至7.0毫米，这取决于灯的特定工作电流额定值。 当灯在水平位置操作时，使用位于灯附近并且位于反射器外侧的磁体来防止电弧向上弯曲。 在电影投影系统的情况下，更短和更强烈的电弧增加了屏幕流明并降低了灯消耗的功率（瓦​​特）。
