Abstract: A thermoelectric ornamental assembly for generating thermoelectric energy in a body adornment like a ring. The assembly uses a thermoelectric effect to generate an applied temperature gradient between an inner layer and an outer layer of the ring. The inner layer both receives and transmits a thermal current away from the skin. The outer layer receives the thermal current.

A thermoelectric layer is sandwiched between the outer and inner layer. The thermoelectric layer includes a substrate portion that supports variably doped semiconductors for creating a difference in conductivity so that the charge carriers can diffuse and create a voltage across the thermoelectric portion. The voltage produces a light visible through a transparent area of the ring.

Abstract: A standard table lamp requires an electrical outlet to supply alternating current (AC) and illuminate a standard AC light bulb, including new technology, low wattage AC light bulbs such as a 7 Watt LED or a 7 Watt CFL.
