Abstract

The invention relates to a flat gas discharge lamp having a discharge vessel and electrodes, the discharge vessel comprising a base plate (1) and a top plate (7) and having at least one spacer element (8) between base plate (1) and top plate (7). Spacer elements usually disrupt the homogeneity of the luminance distribution on the top plate 7. In order to avoid this, the spacer elements (8) are additionally configured as dielectrically impeded electrodes. For this purpose, each spacer element (8) has an electrically conductive component (9) connected to an electrode or current feed. As a result, the spacer elements (8) are actively involved in the discharge and, consequently, in the production of light.
