Abstract
A plurality of light sources are arranged with a light-guide structure such that light emitted by the sources propagates longitudinally through the light-guide structure. The light-guide structure scatters and/or redirects the emitted light and outputs the scattered and/or redirected light laterally. A controller is configured to dynamically correlate the light emitted from the plurality of light sources and to dynamically tune intensity of the light emitted from the plurality of light sources. The result is a dynamic light effect that appears to the observer as moving light.
Claims20
A method, comprising:
- dynamically tuning light intensity from a plurality of correlated light sources;
- and
- emitting the dynamically tuned light intensities longitudinally into a light-guide structure which is configured to scatter and/or redirect the emitted light and to output the scattered and/or redirected light laterally.
An apparatus comprising:
- a plurality of light sources;
- a light-guide structure disposed to longitudinally propagate light emitted by the plurality of light sources through at least a portion of the light-guide structure, and configured to scatter and/or re-direct the emitted light and to output the scattered and/or re-directed light laterally through the light-guide structure;
- and
- a controller configured to dynamically correlate the light emitted from the plurality of light sources and to dynamically tune intensity of the light emitted from the plurality of light sources.
