Abstract
A rotary projector light can include a lamp case defining a hollow mounting chamber and having an open front end; a power supply located inside the lamp case, the power supply connected to a power cable adapted to connect to an external power source; a motor located inside the lamp case, the motor electrically connected to the power supply and having a spindle; a positioning seat mounted on the spindle; a plurality of light emitting diode (LED) elements located on the positioning seat, the LED elements electrically connected to the power supply; and a beam-splitting lens cover located on the open front end of the lamp case. The beam-splitting lens cover can have an inner surface with multiple convex lenses directed at multiple refraction angles.

A rotary projector light, comprising:
- a lamp case defining a hollow mounting chamber and having an open front end;
- a power supply located inside the lamp case, the power supply connected to a power cable adapted to connect to an external power source;
- a motor located inside the lamp case, the motor electrically connected to the power supply and having a spindle;
- a positioning seat mounted on the spindle;
- a plurality of light emitting diode (LED) elements located on the positioning seat, the LED elements electrically connected to the power supply;
- and
- a beam-splitting lens cover located on the open front end of the lamp case, the beam-splitting lens cover having an inner surface with multiple convex lenses directed at multiple refraction angles.
A method of projecting multiple colors of light at multiple angles, comprising:
- providing a rotary projector light having a lamp case and a beam-splitting lens cover, the rotary projector light further having a power source and a motor located within the lamp case;
- rotating a plurality of different colored light emitting diode (LED) elements around an axis within the lamp case;
- and
- emitting light from the plurality of different colored LED elements, the light projecting through the beam-splitting lens cover;
- transmitting electrical power from the power source to the motor to rotate the plurality of different colored LED elements;
- and
- transmitting electrical power from the power source to the plurality of different colored LED elements, wherein the beam-splitting lens refracts the light at multiple projection angles;
- further wherein:
- the motor includes a spindle supporting a positioning seat;
- the positioning seat includes a first face, a second face, and a third face;
- a first LED element, a second LED element, and a third LED element are located on the first face, the second face, and the third face, respectively;
- and
- each of the first LED element, the second LED element, and the third LED element is adapted to emit light of a different color.
