This circuit needs revision...

I think that's what @smdhupkar is hoping someone will provide :-)

Your circuit is configured wrong. Search on bridge rectifier and compare it.

Actually better to search on full-wave bridge rectifier. Not all circuit on EC are correct!

Yes actually I need help to improve this circuit

Here is a circuit to play with. Read a bit more and keep on experimenting, http://everycircuit.com/circuit/6271774206984192

If you want to correct your own circuit - remove bottom connection to the load, move earth connection from 50Hz to cathode (bar end) of LED, flip bottom two diodes, connect bottom of load to junction of two diode anodes.

A more economic design you get by removing the three useless diodes from your rectifier (which is probably meant to be used as two way rectifier bridge but incorrectly connected)
