Title:
FANTASY LAMP COMPRISING A LIGHT-PERMEABLE, LIQUID-CONTAINING HOLLOW CHAMBER AND A MULTITURN DRIVE FOR SAID HOLLOW CHAMBER
Document Type and Number:
WIPO Patent Application WO2002085069
Kind Code:
A3
Abstract:
The invention relates to a fantasy lamp comprising a light-permeable, narrow and hollow chamber (15) receiving at least two immiscible liquids, the rear side thereof being illuminated. Said hollow chamber comprises wall sections (13, 14) arranged at a short distance from each other, and can be rotated about an essentially horizontal axis (10), when the wall sections are essentially vertically aligned. At least one of the liquids is coloured. An electromotive drive (4) mounted in a chassis (1) is provided for rotating the hollow chamber (9). The hollow chamber (15) forms part of a hood (9) and the drive (4) co-operates with a radial outer region (18) of the hood (9). Particularly aesthetic effects can be achieved by one such fantasy lamp, by means of the liquids, when the hollow chamber is slowly rotated about the essentially horizontal axis. Said lamp has a simple structure and can be mass-produced in an economically acceptable manner.
