Ok guys here are the solution.
After several days of investigating and involve friends and you here too, I found the solution and the cos why this is not working on my version of proteus.
I don't really know what this setup means avtually but changing this from 50m to 1m is working.
Here are the pictures where I found it.
It is in the "System" menu.
Under " Set Animation Options "
There is an option called:
" Timestep per Frame "
The value of this was 50m. I don't know what is the " m " unit for. maybe minute, maybe meter.
When I changed this to 1 the simulation of the light bulb started to blinking.
If I put the frequency of the AC power source from 50Hz to 1KHz the same problem is like before.
The lamp is not shining/blinking.
If somebody have any explanation or suggestion what that setup is meaning pls let me know.
Thank you.
