A compact self-ballasted fluorescent lamp (50) includes a fluorescent lamp (1) and an operating circuit (2) for operating the fluorescent lamp (1). The operating circuit (2) includes a circuit board (6), a heat-generating part (7) disposed on a first surface (6a) of the circuit board (6) and generating heat while the fluorescent lamp (1) is operated, and a semiconductor part (17) disposed on a second surface (6b) opposed to the first surface (6a). The area where the semiconductor part (17) is disposed is other than the area corresponding to the area of the first surface (6a) where the heat-generating part (7) is disposed. L'invention porte sur une lampe fluorescente à autostabilisation (50) comprenant une lampe fluorescente (1) et un circuit de commande (2) servant à commander la lampe fluorescente (1). Le circuit de commande (2) comprend une carte à circuit imprimé (6), un élément calogène (7) disposé sur une première surface (6a) de la carte à circuit imprimé (6) et produisant de la chaleur quand la lampe fluorescente (1) est allumée, et un élément semi-conducteur (17) disposé sur une seconde surface (6b) opposée à la première surface (6a). La zone où l'élément semi-conducteur (17) est disposé n'est pas la zone de la première surface (6a) où l'élément calogène (7) est disposé.
