Abstract
A repetitive lighting fixture will alternate between at least two different illuminated images projected in a desired direction. The fixture includes edge-lit flat panels that are configured and/or overlayed to reproduce one or more desired images. Each panel is made of light-transmissive material, which optionally may contain colorant. Each edge-lit flat panel contains optics coupled with a second planar surface of the panel. The optics are arranged to define a desired shape of an image and are configured so as to cause light distributed within the panel to exit a first planar surface of the panel. Each panel has its own light source that projects light into a light transmitting edge of the panel. The panel's light source can include light emitting diodes (LED) that only or selectively illuminate the specific optics of that panel.
