Abstract:
A current holding circuit for a bidirectional triode thyristor (TRIAC) dimmer and a linear dimming driving circuit are provided. The current holding circuit for a TRIAC dimmer is a resistance and capacitance (RC) circuit including a first resistor and a first capacitor connected in series. The RC circuit is connected in parallel with any one of rectifying diodes of a rectifying bridge in the linear dimming driving circuit. The linear dimming driving circuit includes an overcurrent protecting circuit, a rectifying bridge including four rectifying diodes connected, the RC circuit, a surge suppressing circuit configured to absorb a high surge voltage of an input voltage, a filtering circuit, a linear constant-current circuit, and a flicker eliminating circuit configured to eliminate flicker caused by an asymmetrical current of a light emitting diode (LED) load due to the RC circuit.
