摘要：
A control circuit for use in a ballast (100) configured for powering a first lamp set and a second lamp set. The second lamp set is operated via a controller (122B) and a second lamp driver circuit (120B). The controller (122B) enables the second lamp driver circuit (120B) as a function of a monitored value corresponding to a current through a lamp of the second lamp set. The control circuit (170) includes first (172) and second input terminals (174) for selectively connecting to the power supply. The control circuit (170) reduces the monitored value as a function of a connection state of the first (172) and second input terminals (174) of the control circuit (170) to the power supply. Thus, the control circuit (170) causes the controller (122B) to selectively operate the second lamp driver circuit (120B) in order to energize the second lamp set in combination with the first lamp set.
