ABSTRACT:
An electrode for an external electrode fluorescent lamp. The lamp has intensity striations. The electrode has a periodic non-uniform area sufficient to cause a periodic non-uniformity in the electric field between two electrodes. The non-uniformity of the electric field is sufficient to prevent wandering of the striations. The striations have a range of pitch. The pitch of the area in the electrode is within the range of pitch of the intensity striations. Examples of non-uniform areas include serrated or sinusoidal edges and circumferential slits.
