Abstract
An electronic circuit comprises a switching voltage boosting circuit and a current regulating circuit for controlling current flowing through a solid state light source. A control circuit controls the current regulating circuit and the switching voltage boosting circuit to control the magnitude of current flowing through the solid state light source. An error signal produced by the control circuit for controlling the current flowing through the solid state light source may further control the switching voltage boosting circuit.
