Abstract
A lamp has a transparent glass container in which a clear liquid having a plurality of colored lustrous foil fragments floating in the liquid is contained, and a frosted shade covering the glass container with a clearance left between them. Light projected by the lamp on the floating lustrous foil fragments is refracted onto the frosted shade to show dynamically changeful luster and shadow on the frosted shade, creating novel and unique decorative effect. The glass container and the frosted shade may be of any shape and may have different wall thickness at different locations to enhance the decorative effect of the lamp.
Claims8
A lamp showing dynamically changeful luster and shadow, comprising a base in which a light-emitting means is mounted, a transparent glass container connected to a top of said base for containing a low-boiling-point clear liquid and a plurality of differently colored lustrous foil fragments floating in said clear liquid, and a thin shell of frosted shade that is light-penetrable and vision-impenetrable and covers an outer surface of said transparent glass container with a predetermined clearance left between said shade and said glass container;
- said light-emitting means projecting hot light upward and therefore heating a bottom of said transparent glass container to cause said clear liquid to convect in said glass container and bring said lustrous foil fragments floating in said clear liquid to move up and down in said glass container, light projected by said light-emitting means onto said differently colored lustrous foil fragments being refracted to produce colored rays of light that penetrate said transparent glass container and project on said frosted shade and therefore forming dynamically changeful luster and shadow on said frosted shade that can be viewed from outside of said frosted shade.
