| Abstract: |
A lamp having a moving luminous aesthetic effect made up of a luminous incandescent source directed through a transparent container above the luminous source and being filled with a liquid mixture of trichloroethylene and dichloroethylene having dispersed therein a plurality of platelets adapted to float in the liquid, each of the platelets having at least one reflecting surface thereon.

I claim:
1. A lamp with changing luminous effects comprising means to provide heat and light and a transparent container located adjacent said means to provide heat and light; said container being filled with a mixture of liquids, the density of the liquid mixture varying with the temperature of said means to provide heat, the liquid mixture having metallized platelets dispersed therein which have a thickness which, related to the surface thereof and to the density of the liquid mixture at room temperature, is such that said platelets float on said liquid at room temperature, but do not float when said liquid has been heated by said heating means; the platelets each having at least one face which has been polished to reflect the rays emitted by the means to provide light; the means to provide heat and light generating a movement of the platelets within the liquid and sparkling of the luminous rays, due to the reflection produced by the polished faces of said platelets, the motion of the platelets resulting from convection currents in the liquid mixture and variation in density in the liquid due to the heating effect of said means to provide heat.
