Minimalist LED bulb/lamp (with schematic)

This is a very simple LED lamp designed for decorative, sign and festoon use. It has one of the lowest component counts I've seen, and uses the higher voltage multi-chip LEDs to allow a very basic resistive current limiter.

Each of the four LEDs has six LED chips in it to give the equivalent of a 24 LED string. If they'd used the 12 chip version of the LEDs it would have increased the efficiency, and a very low value capacitor could have been used to remove the slight 100/120Hz flicker.

The low power and minimalist circuitry means that these lamps should be extremely reliable.

Although designed for 220-240V use, the lamps should work on 100V upwards at lower intensity.
