A look inside a TCP branded 2W GU10 LED lamp.
Quite a neat lamp with the front lens retaining ring clipped in flush with the front, but coming out easily. Inside is a typical plastic reflector/lens and a small PCB with three 3030 surface mount LEDs wired in series with the track underneath covering most of the area of the PCB to assist in thermal dissipation. The PCB has an aluminium base that is screwed onto the thermally conductive plastic body of the lamp. The screws also hold the front of the housing to the back which contains a mains voltage buck regulator.
The chip had very hard to read markings on a less than smooth surface, but what I could glean from it SO1213 (date code?) AR81226 (chip code?) AD2431. None of those brought up a buck regulator style of chip on a quick Google search.
