<p>A low-pressure mercury discharge lamp according to the invention is provided with a discharge vessel (1) which encloses a discharge space (2) in a gastight manner and in which a filling comprising mercury is accommodated. The lamp is in addition provided with means (3a, 3b) for maintaining an electric discharge in the discharge space. The discharge vessel is provided with a luminescent layer (5). The lamp generates light during operation with a spectrum which is substantially composed of radiation in a first wavelength region from 590 to 630 nm, in a second wavelength region from 520 to 565 nm, and in a third wavelength region from 430 to 490 nm. The radiation in a wavelength interval from 590 to 600 nm accounts for at least 25 % of the power of the radiation in the entire first wavelength region. As a result, the lamp is an attractive proposition for applications where a mediocre color rendering can suffice.</p> |
