Abstract
A light fixture with rotatable light source includes a fixed lamp holder, a rotatable lamp holder, a light source assembly, a power source and a transmission mechanism; and the light of the light source assembly has strong and weak changes while rotating with the rotatable lamp holder within the circumferential range of the rotation centerline; the power source and the transmission mechanism are used to drive the rotatable lamp holder to rotate relative to the fixed lamp holder. The light fixture with rotatable light source drives the light source assembly to rotate through the rotatable lamp holder, the light intensity changes during the light source assembly rotates around the center line of rotation. The light fixture will produce a sparkling effect especially suitable for jewelry lighting, so that jewelry is shining at all times.
