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.

This invention takes the idea of portable lighting and standardizes the form factor by using already developed standard low wattage AC light bulbs such as LED and CFL and standard AC light bulb sockets embedded in the design.

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.
