Abstract:
In various embodiments, a circuit arrangement for operating a series circuit of a first and a second low-pressure gas-discharge lamp is provided, which may include an input with a first and a second input connection for application of a supply voltage; an output with a first arrangement, which has a first and a second connection pair for connection of the first lamp, and a second arrangement, which has a first and a second connection pair for connection of the second lamp, wherein a first connection of the second pair of the first arrangement is coupled to a first connection of the first pair of the second arrangement; a resonant circuit; and a capacitive voltage divider, which has a first capacitor, which is coupled in parallel with the first arrangement, and a second capacitor, which is coupled in parallel with the second arrangement.
