Zusammenfassung:Methods for driving solid state light sources are provided. A method comprises: determining if a first solid state light source load (206) driven by a first drive circuit (212) is illuminated based on a voltage corresponding to the voltage across the first solid state light source load (206) generated in a feedback and control circuit (218); and controlling the first drive circuit (212) based on the voltage corresponding to the voltage across the first solid state light source load (206) by adjusting a reference voltage in the feedback and control circuit (218), when it is determined that the first solid state light source load (206) is not illuminated.
