ABSTRACT:
An incandescent heating unit uses a low wattage incandescent light bulb to warm the occupant of a metal chair. The light bulb generates heat which is absorbed by the metal and radiated to the occupant. A dispersion disk spaced between the bulb and the chair prevents the formation of a hot spot in the portion of the chair nearest the bulb.
