| 摘要 |
The invention relates to a circuit arrangement in which each circuit component (15) is electrically connected to a conductor track (60) of a flexible conductor track support (6). The flexible conductor track support is arranged, together with the circuit components connected thereto, in a folded configuration inside an interior space (70) of a liquid-tight housing (7). This interior space is filled with a cooling liquid (8), which is not electrically conductive and is contact with all circuit components (15). This enables the circuit arrangement to be provided with a compact design while being relatively small, and all components, including the passive ones, are equally cooled. The invention is provided for use in lamp ballasts.
