| Title: |
Marketplace Illumination Methods and Apparatus |
| Abstract: |
Methods and apparatus for providing illumination in a marketplace. In one
example, radiation comprising variable color light is generated using a
plurality of LEDs. One or more articles in the marketplace are
illuminated with the generated radiation, and the spectral content of the
generated radiation is controllably varied over a period of time so that
a customer of the marketplace perceives a change in color and/or an
illusion of motion associated with the article(s) due to a selective
color interaction between the generated radiation and the article(s).
Examples of marketplaces include, but are not limited to, consumer
environments, work environments, sporting environments, entertainment
environments, retail establishments, restaurants, museums, art galleries
and the like.
