Abstract

A light emitting apparatus includes a first stepper motor, a mounting frame, a second stepper motor, at least one reflector, and a light source. The first stepper motor has a first rotor and a first output shaft coupled to and driven by the first rotor. The frame is fixed to and rotates together with the first output shaft. The second stepper motor has a second rotor and a second output shaft coupled to and driven by the second rotor. The second stepper motor is mounted on the mounting frame such that the second output shaft is transverse to the first output shaft and is rotatable relative to the mounting frame. The reflector is fixed to and rotates with the second output shaft, and has a light reflecting surface and a plurality of differently colored reflecting facets disposed around an axis of the second output shaft and on the reflecting surface. The light source is radially spaced from the first output shaft such that light emitted by the light source is reflected by the light reflecting surface of the reflector when the mounting frame is turned stepwise by the first output shaft so as to move the reflector on a route of the emitted light.
