Abstract (en)
[origin: WO2010081571A2] The invention relates to a detector circuit for controlling a fluorescent lamp, wherein actuation of at least one fluorescent lamp occurs depending on a first signal at a first input and depending on a second signal at a second input, in particular by means of a half-bridge inverter if the first signal and the second signal are each greater than a first prescribed voltage and less than a second prescribed voltage. The invention further relates to a ballast and to a method for actuating the at least one fluorescent lamp.
