Abstract
A multiple image LED projector comprises an array of LED elements directing light beams through a multi-frame image film focused by an array of lenses onto the same position on a projection surface. By lighting the LEDs in sequence, a slide show or animation sequence is projected onto the projection surface. The sequence can be played in reverse, or in different order of images for different effects.
