Ac led dimmer

I used the incandescent lamp dimmer circuit for dimming ac led bulb.But it doesn't turn off and on completely.Flickering also happening.A resistor was placed across output(bulb) but it gets hot and melt.I tried solid state relay (g3mb 202p) and blinking was done successfully in led bulb through arduino.But using pwm causes flickering.So is there any combined circuit of MOSFET and SSR for ac led dimmer using arduino?The MOSFET dimmer circuit is attached along with this.

    Have you tried a small capacitor in series with the resistor?

    Ya.I tried.Also I used a SSR in series with input ac supply.but here only proper blinking of led bulb is done,but it can't fade.I give blink program to SSR and fade to MOSFET part.The output was blinking with fading.
