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.

1. A lighting fixture, comprising: a first edge-lit flat panel, a second edge-lit flat panel overlaid the first edge-lit flat panel, and a third edge-lit flat panel disposed in viewing alignment with the first edge-lit flat panel,each edge-lit flat panel formed of a light-transmissive material and including a first planar surface, a second planar surface opposite and separated from the first planar surface, and optics coupled with the second planar surface;wherein the optics of the first edge-lit flat panel are arranged to form a desired shape of an image of the first edge-lit flat panel and configured to reflect light distributed within the first edge-lit flat panel through its first planar surface, andwherein the optics of the second edge-lit flat panel are arranged to form a desired shape of an image of the second edge-lit flat panel and configured to reflect light distributed within the second edge-lit flat panel through its first planar surface, andwherein the optics of the third edge-lit flat panel are arranged to form a desired shape of an image of the third edge-lit flat panel and configured to reflect light distributed within the third edge-lit flat panel through its first planar surface; wherein: the optics of the first edge-lit flat panel defines less than a complete first image;the optics of the third edge-lit flat panel defines less than a complete first image;and the image formed by the optics of the first edge-lit flat panel when combined with the image formed by the optics of the third edge-lit flat panel defines a complete first image; and wherein:the optics of the first edge-lit flat panel define less than a complete second image;the optics of the second edge-lit flat panel define less than a complete second image;and the image formed by the optics of the first edge-lit fiat panel when combined with the image formed by the optics of the second edge-lit flat panel defines a complete second image;the complete first image and the complete second image being different. 2. The lighting fixture of claim 1, wherein when supplied with power said fixture is capable of serially projecting the complete first image and the complete second image. 3. The lighting fixture of claim 1, further comprising a light source coupled with each of the first edge-lit flat panel, the second edge-lit flat panel, and the third edge-lit flat panel. 4. The lighting fixture of claim 3, wherein the light source is configured and disposed to only illuminate or selectively illuminate the first and third edge-lit flat panels or the first and second edge-lit flat panels. 5. The lighting fixture of claim 3, wherein said light source includes a strip of PCB containing light emitting diodes.
