PCT No. PCT/NL93/00073 Sec. 371 Date Nov. 19, 1993 Sec. 102(e) Date Nov. 19, 1993 PCT Filed Mar. 26, 1993 PCT Pub. No. WO93/20579 PCT Pub. Date Oct. 14, 1993A meander-shaped low-pressure mercury discharge lamp with cold electrodes (7, 8), in particular for use in an illumination panel for a liquid crystal display. The geometry of the tubular lamp vessel (1) bent into a meander shape is so chosen, for obtaining a good homogeneity of the luminance and a high luminous efficacy, that the length of the discharge path is between 250 and 1000 times the internal diameter of the lamp vessel (1). The internal diameter of the lamp vessel (1) preferably has a value of between 2.0 and 3.5 mm.
