ASDA LED lamp.

A look at the insides of an ASDA branded LED lamp. I noticed they seemed to be clearing out their stock of certain ranges and doing the same with the overpriced Duracell branded lamps too.
First surprise was the thickness of the plastic LED cover. So thick and solid that I thought it was glass with a protective coating. Perhaps that's part of the heat dissipation system? The cover was removed (with extreme force) to reveal a universal potted module inside with the array of LEDs mounted on a mtal core PCB which was then mounted on a stepped aluminium plate and then an aluminium shell that contained the circuitry potted in an easily removed white rubbery heat transfer compound. The only components protruding from the module were the capacitor and fuse. Presumably to keep the electrolytic capacitor away from the heat and also to allow the module to be used in a wide range of narrow bases.
The circuitry looks like a buck regulator and uses a chip with the following three numbers on it:- TCP1213 (possibly a manufacturer and date code)
CDO8617
TnD3221
I couldn't find any data on the chip online. I presume it may be a standard regulator chip but with custom markings.
Actually quite a neat lamp.
