Abstract
A decorative lamp with illuminated color changeable column generally includes a base for supporting the lamp on a surface, a translucent column having a first end extending upwardly from the base and a second end opposite the first end, an electrical light socket connected to the second end of the translucent column for removably connecting an electric light bulb thereto and electronic circuitry for operating the lamp. The base of the lamp contains at least one light emitting device therein and the first end of the translucent column is connected to the base adjacent the light emitting device. The translucent column includes at least one fiber optic strand extending from the first end to the second end of the column so that light emitted from the light emitting device is transmitted along a length of the optic strand and is visible through the translucent column.
