Abstract:
An LED light device includes an LED night light or LED bulb having a moving projection image. The movement effect is obtained by (1) causing LEDs to illuminate with a time difference, (2) using a magnetic field force to cause a film, opening, printed piece, or slide to move, shake, spin, rotate, or vibrate, or (3) using a motor or movement to cause the film/opening/printed piece/slide or a projection-lens to move, shake, spin, rotate, or vibrate. Light beams from an LED light source pass through the film/opening/printed piece/slide and then through a projection lens that causes a tiny lighted image to become a bigger or more colorful moving projected image having a wider viewing angle.
