Abstract:
1. A reflective mechanism for a stage lamp, the stage lamp including a body and a support member mounted on the body, the reflective mechanism comprising: a base fixed on the support member, the base including an axial hole; a first motor mounted to the base, the first motor including an output shaft with a first gear; a first transmission device including a hollow shaft rotatably extending through the axial hole of the base and a first driven gear mounted on the hollow shaft to turn therewith, the first driven gear being meshed with and driven by the first gear, the hollow shaft further including a fork on an end thereof; a bracket including a bottom fixed on the base and a wall extending from the bottom; a second motor mounted on the wall of the bracket, the second motor including an output shaft with a second gear; a second transmission device including an endless cord and a second driven gear meshed with the second gear, the second driven gear including a pulley extending from a side thereof; a mirror frame including a bottom plate and a pivotal portion, the pivotal portion being pivotally mounted to the fork of the hollow shaft, the endless cord being wound around the pulley and the pivotal portion of the mirror frame, allowing joint rotation of the mirror frame and the second driven gear, the endless cord extending through the hollow shaft without interfering with rotation of the hollow shaft; and a reflective mirror mounted on the bottom plate of the mirror frame to turn therewith; wherein when the first motor turns, the mirror frame together with reflective mirror rotates about a longitudinal axis of the hollow shaft; and wherein when the second motor turns, the mirror frame together with the reflective mirror pivots about a pivotal axis of the pivotal portion.
