Abstract
Proposed is a driver circuit for a lighting device which caters for both a control method using an electronic control signal and a manual control signal. The driver circuit has a power control circuit and a selection circuit. The selection circuit is configured to control the power control circuit so that a manual control signal is either employed or disregarded. In this way, the power control circuit may be controlled to set the output power of the driver circuit according to either the manual control signal or an electronic control signal. Specifically, the electronic control signal is prioritized over the manual control signal when the electronic control signal is valid.
