Lamp with decorative element when illuminated

Abstract

A lamp apparatus includes a pair of concentrically positioned lamp shades and a light source positioned centrally within an inner one of the lamp shades. The lamp shades are bell shaped so as to direct light from the light source downwardly without passing through either one of the lamp shades. The outer one of the lamp shades is formed of a transparent glass or plastic with a thin film optical coating of randomly variable thickness on its inner surface. The inner one of the lamp shades is formed of a translucent glass or plastic. Standard lamp hardware is used to assembly the apparatus into a functional lamp assembly. When the light source is not illuminated, the outer shade appears as a metallic or chrome color, and when it is illuminated, the outer shade appears transparent and the inner shade appears to have a rainbow colored effect. Downward directed light is not colored.
