摘要： An electric lamp having a coiled filament and at least one intermediate filament support which effectively restrains the filament from excessive swaying or sagging whereby premature lamp failure because of electrical shorting of the filament or thermal shocking of the glass envelope is substantially reduced. The intermediate filament support includes at least one flat segment interposed between two adjacent turns of the outermost coil of the filament. The maximum thickness of the flat segment is less than the winding separation of adjacent turns of the outermost coil. In preferred embodiments of the invention, the intermediate support encloses but does not grasp the filament so that no coil of the filament, inner or outer, is distended in the process of closing the support about the filament. A support in accordance with the invention effectively restrains filament movement in directions along and normal to the filamentary axis. The invention may be employed, singly or in multiples, in any incandescent lamp or any lamp employing an incandescent filament and is particularly appropriate for filaments designed to operate at relatively high voltages as is the situation in many European applications.
摘要翻译：一种具有螺旋丝和至少一个中间细丝支撑的电灯，其有效地限制细丝过度摇摆或下垂，从而大大减少了由于灯的电短路或玻璃外壳的热冲击引起的过早的灯故障。中间丝线支撑件包括至少一个插入在灯丝的最外面线圈的两个相邻匝之间的平坦段。平坦段的最大厚度小于最外面线圈的相邻匝的绕组间隔。在本发明的优选实施例中，中间支撑件包围但不抓住灯丝，使得在围绕灯丝关闭支撑件的过程中，内部或外部的细丝的线圈不会膨胀。根据本发明的支撑件有效地抑制沿着和垂直于丝状轴线的方向上的细丝运动。本发明可以在任何白炽灯或使用白炽灯丝的任何灯中单独或多次地使用，并且特别适用于设计为在较高电压下工作的灯丝，如在许多欧洲应用中的情况。
