hello,

specifies caracteristics of your buble lamp .. voltage,Watt
you can't use triacs in DC
use a MOSFET to control the buble
How do you want to control the buble , just ON/OFF or graduate control 0 to 100% ( and PWM signal given by your PIC)
 

I wanna use it to dimming DC bulb or LED
using mosfet or transister on GP0 instead of triac

You need a significant change in the schematic and about half the code re-writing are you sure you want to do this?
A PIC with a PWM module would be far better suited to this task, the nearest to the 12F629 would be the 12F683.

Brian.
