Abstract

Abstract A toy lamp comprises a transparent housing cover, a casing containing revolution driving assemblies, a revolving frame to drive a revolving ball into crosswise revolution, a revolving frame crosswise driving assembly, a revolving ball having a plurality of translucent openings from which differently colored light beams are transmitted, a revolving ball lengthwise driving assembly, a power supply unit for a light bulb inside of the revolving ball and a casing base with shockproof function. The revolving ball inside the housing could revolve in both crosswise and lengthwise directions slowly upon supply of electricity and out of a plurality of translucent openings of its ball wall transmit an interlaced moving of the light beams in different colors. It could be used as light source in a paper fancy lantern or utilized alone in alternative.
