Abstract (en)
[origin: US6304028B1] A discharge lamp (1) having an electrically conducting screen (12, 13) which at least partially surrounds the discharge vessel (2). The electrodes (3-5) are separated from the interior of the discharge vessel (2) by a dielectric barrier (6-8). Moreover, this screen (12, 13) is electrically separated from the electrodes (3-5) by a dielectric (2). In order largely to prevent the electric power fed to the lamp electrodes (3-5) during operation from being capacitatively coupled to the electrically conducting screen (12, 13), the thickness dB and the dielectric constant ∈D of the dielectric (2), as well as the thickness dB and the dielectric constant ∈D of the barrier (6-8), which separates the electrodes (3-5) from the gas filling, are specifically mutually coordinated such that the following relationship is fulfilled:
