inserted in parallel with the led light bulb 102 when switch 604 is activated or turned on switch 604 is controlled by mosfet 702 which in turn is controlled by the voltage at common node c to illustrate assume mosfet 702 is off or inactive e g the gate to source voltage vgs of mosfet 702 is below its threshold voltage vt with mosfet 702 off switch 704 is closed which couples bleeder resistor 602 in parallel with light bulb 106 via bridge 600 also assume triac 120 is initially inactive or turned off and as a result no current flows therethrough or through bleeder resistor 602 on the other hand because switch 604 is closed prior to activation of triac 120 triac 120 can draw current through bleeder resistor 602 when triac 120 is first activated as line voltage v 1 increases capacitor 114 integrates charge which in turn increases the voltage across diac 116 eventually this voltage exceeds the diac breakover voltage at which point diac 116 conducts current to the gate of triac 120 during the pulse as described above with the pulse current begins flowing through bleeder resistor 602 and triac 120 bleeder resistor 602 should be sized so that the current flowing triac 120 exceeds a latching current when the diac pulse ends the voltage at common node c within switch circuit 606 continues to increase more particularly as current flows through resistor 704 and into capacitor 710 the voltage on capacitor.
