摘要： Ballasts and LED drivers are presented for powering at least one light source, in which a shunt circuit provides a high impedance to allow operation of the light source when the AC input power exceeds a power threshold value, and provides a low impedance when the AC input power is below the power threshold value to prevent an output power stage from providing power to the light source.

摘要： A ballast or drive circuit is located between a dimmer switch and at least one light source or lamp. The ballast includes an electromagnetic interference (EMI) filter operatively disposed between the dimmer switch and the at least one lamp. The EMI filter includes an inductor. A low pass filter, preferably an inductor, is serially connected to the inductor of the EMI filter and situated between the dimmer switch and EMI filter for addressing currency ringing, reducing high current peaks, and decreasing flickering that would otherwise result with multiple light sources when the lamp is turned on.
