Sorry I can't let this go you said and I quote. "LED transformers don’t exist LED drivers do though"
Which I took on face value LED transformers do exsit as part of the circuitry of LED drivers
The output of any transformer from a AC supply will always be AC and is only when converted to DC...
Purely from the point of view of the transformer there no difference between a transformer in either a driver built within an LED lamp or a transformer built within a stand alone driver or any other form of LV lighting other than size and transformer configuration I was just making the point...
At the risk of being pedantic LED step down transformer forms part of the driver as per the attached diagram shows, what has intrested me is the method of rectification used being not full rectification you will note the use of only two diodes to form a half bridge effectively producing a DC...
