But so far away from the perfect sense of using the perfectly well established and perfectly descriptive and perfectly satisfactory term "power supply" as to be another perfectly bonkers example of the perfectly ridiculous compulsion people seem to have to coin new terms, or corrupt the meaning of existing ones.
Come on now, that is very unfair to the capacitors, transistors, resistors and other components inside the box.
And not all SMPS have a transformer. some of the really cheap and crappy ones avoid the cost of a transformer, after all does it matter if one side of the output is connected to the Neutral of the input. Live is chopped via a transistor and capacitive coupled to the other side of the output.
It is only a few inches of cable from the "SPMS" to the lamp which could have been a 230 volt with Live and Neutral connected directly to it so if one side is connected to Neutral it is no more hazardous than a 230 volt lamp would be.
I am being sarcastic but there are such devices on sale made by and sold by people who trade un-ethically and have no regard for the people to whom they are selling.

Or you could take the view that a transformer is an electrical device that transfers energy between two or more circuits through electromagnetic induction, and that the Oxford dictionary definition is wrong.

One could take that view, and the minds of most of us 'oldies' probably do. However, the moment we start saying that dictionaries, particularly the Oxford dictionary, are 'wrong', it is not obvious what we can then regard as the official determinant of 'right' as far as the meaning of words is concerned.
An old definition of a television set which explained how it worked rather than merely what it does would contain references to valves and cathode ray tubes which would lead to the same argument from winston about what he watches.
"It's not a television!" without considering what tele-vision actually means.
You've mentioned that before. ... But have you seen this: http://en.wikipedia.org/wiki/Lamp ?
Lamp (electrical component), a replaceable component that produces light, such as: .....
Light fixture, or luminaire, often colloquially known as a lamp

You have cited just two of the seven items in the Wikipedia's list of the meanings of 'lamp' (in the context of Lighting). Had the Wikipedia existed 30 years (or whatever) the list would have been much the same, but with that one 'electrical component' definition not being there. In those days (and for decades/centuries/millenia prior to that), a lamp was an item which used oil, gas, a 'light bulb', tube or whatever to produce light - and that was a very well-established proper meaning, in no way 'colloquial'.
IMO, the fact that ambiguity has resulted from the "corruption of the (prior, and very well-established) meaning of existing words" seems to become pretty apparent when someone walks into a shop and asks for "a lamp for their lamp".
That's fine for determining the terminology/jargon to be used by specialists within an industry, but it's of little use to the general public, who one can't blame for relying on standard English dictionaries.
