I am working on another project called electronic level control and have been trying to find a way of switching on the LED using an Opto Isolator. For more than just this project.
It has now become some what of an Obsession now to to get it working.
Attached is the circuit Diagram I used to try and switch on a Lamp just for testing purposes. This Is before I replace it with the LED driver.
Problem I am having is, This does not work.
When I push the switch I get 7 Volts on the gate so I assume the opto is working. However the Light Is not coming on.
When I release the switch the gate voltage goes off so I am assuming it is something to do with the MOSFET
Really would appreciate some help
