ABSTRACT:
A reflective mechanism includes a base fixed on a support member of a stage lamp, a bracket fixed on the base, a mirror frame, and a reflective mirror mounted on the mirror frame. A hollow shaft rotatably extends through an axial hole of the base and includes a fork on an end thereof. The hollow shaft is driven by a first motor mounted on the base to turn about a longitudinal axis of the hollow shaft. The mirror frame includes a pivotal portion pivotally mounted to the fork of the hollow shaft. The pivotal portion of the mirror frame is driven by a second motor to pivot through transmission by an endless cord that extends through the hollow shaft without interfering with rotation of the hollow shaft.
