Yes I do get a linear power output from the driver circuit which already exists.

My power supply is a 220V AC supply. The driver circuit for the led arrangement gives an output of 35 V and 0.35 A which goes into the led lights. I need to insert a pwm circuitry to the dc output of the driver circuit so that the brightness can be reduced. The led's are already working at...

The driver circuit is a constant current source.

Hi, The driver circuit of the led light I am currently working on gives a dc output of 35V/0.35A. This goes to light the led's. I want to perform pulse width modulation in between these two steps. So I need some circuitry that can take an input of 35v/0.35A and perform PWM on it which then goes...

The led's are simple white led's used in any led lamp.

No it is a completely different thing that is ask for. Google "Pulse Width Modulation"

I am doing a project where I need to control brightness of a led light. according to presence. the brightness can be controlled using pwm but I cannot find a way to do that for high voltage input signals.
