The heat source is formed as an essentially flat sheet on the side of the lamp opposite the display, with the heat source connected is series with a PTC type temperature sensor. In order to achieve a uniform and rapid establishment of the optimum operating temperature of the fluorescent lamp, the heat source is formed by a temperature-controlled foil-type heating element.
