A lamp base assembly with electronic ballast for energy-saving lamp includes a housing (22), a lamp cap (21) and an electronic ballast (24) with transistors (23) provided within the housing. A transistor heat-diffusing means surrounding each transistor is provided within the lamp base, for enhancing the heat transfer from the transistors to the housing or the lamp cap, so that the heat generated from the transistors could be transferred out of the lamp base assembly. Thus, the heat-diffusing ability of the transistors is improved, and the working temperature of the transistors could be kept within a safe scope, so that the lifetime of the energy-saving lamp is guaranteed.
L'invention concerne un ensemble culot de lampe à ballast électronique pour une lampe à économie d'énergie. L'ensemble culot de lampe selon l'invention comprend un boîtier, un culot de lampe et un ballast électronique, des transistors étant placés à l'intérieur du boîtier. Le culot de lampe comprend un moyen diffuseur de chaleur entourant chaque transistor afin d'améliorer le transfert de chaleur des transistors vers le boîtier ou le culot de lampe, de sorte que la chaleur générée par les transistors peut être transférée hors de l'ensemble culot de lampe. On améliore ainsi la capacité des transistors à diffuser la chaleur, ce qui permet de maintenir la température de service des transistors à l'intérieur d'une plage sûre et donc de garantir la durée de vie de la lampe à économie d'énergie.
