PIR LED lamp teardown. (With schematic.)

The LED lamps with PIR (Passive Infra Red) detectors in them seem to have become a common thing. So I thought it was time to buy a recent model and take it to bits. This one was surprisingly modular with three distinct PCBs one of which had two sections of circuitry on it.
