Design and simulation of hollow rotating lamp frame for stage

According to the functional requirements for the hollow rotating lamp frame on the stage, its working principle is analyzed in the paper. The overall structure design is determined. The structure designs for body parts, connecting parts, power supply, hanger and rotating parts composed to the lamp frame are completed. The theory analysis and calculation to the power of rotating part are finished so as to select the transmission way of the power and the drive device. In terms of the principle of electric slip ring, a kind of device getting the electricity is designed, which has compact structure and high safety performance. 3D solid model of the rotating lamp frame is established by using Pro/E 3D design software.
