ABSTRACT:
Light processing apparatus creates visual effects with light from a light source. An input bundle of flexible fibre optic light guides receives light from the light source. A reconfiguration plate reconfigures the output ends of the light guides into a plurality of separated input zones of selected shape. A filter having colored areas shaped to correlate with the input zones filters the light. An output bundle of flexible fibre optic light guides distributes the light transmitted through the filter. A configuring plate configures the input ends of the output bundle of light guides into output zones which correlate with the input zones. The filter may be a rotatable color wheel or a computer-controlled liquid crystal display. When the filter is activated, the colored areas change colors, thereby creating various visual effects, such as painting with light. The light processing apparatus can be incorporated into a sign or other lighting product having a display panel or other device for displaying the visual effects.
