(i) one of a motor, time movement, or magnetic-unit and magnetic-coil set, and (ii) one of a controller, IC, or a sensor, to control turn-on and turn-off the more than one LED,

wherein the moving device causes at least one of (a) at least one of the LEDs, (b) the image-carrier or a holder having a plurality of image carriers, and (c) a projection lens or holder having a plurality of optics lenses to move, rotate, swing, wave, shake, spin, or change position to cause said big size projected image and/or lighted-patterns to move, wave, rotate, spin and/or changing position, color, focus, or brightness functions.

2. The LED outdoor light for projecting images or patterns as claimed in claim 1, wherein the light beams emitted by the at least one of the LEDs to pass through a printed window, film, slide, opening, cut-out, stencil, or display-unit of the image carrier to form shaped or tiny-image light beams, which are emitted to the projection lens to form a wider viewing angle projected image.

3. The LED outdoor light for projecting images or patterns as claimed in claim 1, wherein the projection-assembly fits into an LED plug-in night light.

4. The LED outdoor light for projecting images or patterns as claimed in claim 1, wherein the projection-assembly fits into the LED bulb.

5. The LED outdoor light for projecting images or patterns as claimed in claim 1, wherein the motor has a gear set to change a high motor speed to a desired lower speed to rotate at least one of the image carrier, the projection lens and the projection assembly.

6. The LED outdoor light for projecting images or patterns as claimed in claim 1, wherein the movement has a desired rotational speed and the image carrier is one of a fixed, replaceable, detachable, movable unit that fits within a slot, opening or receiving space in the LED outdoor light body.
