Abstract
Abstract A decorative light source consisting of a group of incandescent bulbs covered by a suspended translucent plastic dome. Each of the incandescent bulbs is controlled by an independent blinker switch, so that the flashing of the lamps is in random order. The suspended plastic dome is fastened by a fine piece of thread from above. The dome is consequently set in a spinning motion by the thermal air currents generated by the heat of the flashing lamps, resulting in the projecting of random non-repetitive color patterns on the walls and ceiling of the room in which the lights are located.

Claim 1
Independent Claim
153 words
A decorative light source which projects random moving light patterns on nearby walls and on the ceiling, consisting of a group of colored incandescent light bulbs mounted in mating lamp sockets, with a translucent plastic dome suspended by a thread directly above the mounted light bulbs, with each light bulb independently controlled by a flasher unit such that all bulbs flash in random sequence when the lamp sockets are connected to a common source of electricity, in which the lamp sockets are mounted in the upper surface of a base structure, with a vertical rod which is mounted to the base structure suspending the plastic dome directly above the lamp sockets, such that the projected light patterns emitted on the walls and on the ceiling are varied by the pendulum-like rotation of the translucent plastic dome, with the rotation of the dome and the projected light patterns being automatically periodically reversed in direction.
