Abstract: This invention relates to a fluorescent lamp with a discharge vessel enclosing a discharge path and containing a gas fill. The gas fill may be by excited by a discharge arc. The discharge vessel has at least two sections located adjacent to each other. There are bypass means for providing a bypass path for the gas discharge during a startup of the lamp between the two adjacent sections of the discharge vessel. The bypass path results in a short-cut across the impedance of a portion of the discharge path. A method for starting a discharge arc of the fluorescent lamp is also disclosed. In the method, a voltage is applied between two electrodes across the discharge path, and a bypass path is provided between two ends of a bypassed part of the discharge path. The discharge path is divided into a bypassed part and a remaining part. The combined impedance of the bypass path and the associated bypassed part is selected to be lower than the impedance of the associated bypassed part, and thereby a relatively increased voltage is provided across the remaining part. The gas fill is excited in the remaining part of the discharge path with the help of the increased voltage. Thereafter the impedance of the remaining part is lowered and the voltage across the bypassed part is increased. Finally, the gas fill is excited in the bypassed part by the relatively increased voltage across the bypassed part.

Abstract translation: 本发明涉及具有放电容器的荧光灯，放电容器包围放电路径并且包含气体填充物。 气体填充可以通过放电电弧激发。 放电容器具有彼此相邻的至少两个部分。 存在用于在放电容器的两个相邻部分之间的灯起动期间为气体放电提供旁通路径的旁路装置。 旁路路径导致跨过放电路径的一部分的阻抗的短路。 还公开了一种用于启动荧光灯的放电电弧的方法。 在该方法中，在放电路径之间的两个电极之间施加电压，并且在放电路径的旁路部分的两端之间设置旁路。 放电路径分为旁路部分和剩余部分。 选择旁路路径和相关的旁路部分的组合阻抗低于相关绕组部分的阻抗，从而在剩余部分两端提供相对增加的电压。 借助于增加的电压，气体填充物在放电路径的剩余部分被激发。 此后，剩余部分的阻抗降低，旁路部分的电压增加。 最后，通过旁路部分的相对增加的电压，在旁路部分中激发气体填充。
