COMPACT LOW-PRESSURE MERCURY VAPOR DISCHARGE LAMP FOR ILLUMINATION OF A DISPLAY DEVICE

摘要

A compact low-pressure mercury vapor discharge lamp for illumination of a display device has a dual-shaped lamp part comprising first, second and third tubular portions (11, 12, 13). The second and third tubular portions are arranged in line with each other and alongside the first tubular portion. A first end portion (11 a) of the first tubular portion and a first end portion (12a) of the second tubular portion are interconnected via a first tubular interconnection means (14). A second end portion (11 b) of the first tubular portion and a first end portion (13 a) of the third tubular portion are interconnected via a second tubular interconnection means. A second end portion (12b) of the second tubular portion and a second end portion (I 3b) of the third tubular portion face each other. First and second electrodes (22, 23) extending in radial direction are provided in the vicinity of the second end portion of the second tubular portion or of the third tubular portion, respectively.
