ABSTRACT: The invention relates to an electrical device for igniting and supplying a low-pressure mercury vapour discharge lamp (11) which is provided with two preheat- able electrodes (12,13). A series arrangement (12, 4, 14, 13) comprising the two electrodes (12, 13), a PTC resistor (14) and a second winding (4) of a transformer fed back negatively with respect to a first winding (3) thereof is connected to a connection point of the first transforming winding. According to the invention, this series arrangement (12, 4, 14, 13) is further connected to a second connection point of the first transformer winding (3), Thus, the electrical device may readily ignite and supply the lamp whilst also results in that the electrical device being capable of withstanding the situation which arises should the lamp fail to ignite even though the lamp electrodes (12, 13) are uninter- rupted.
