Marketplace illumination methods and apparatus
First Claim
1. A method of providing illumination in a marketplace, comprising:
- a) illuminating at least one article in the marketplace with variable color light from a plurality of LEDs, the marketplace comprising a consumer environment configured for the sale or purchase of goods or services, the plurality of LEDs comprising a first LED providing a first output having a first spectrum and a second LED providing a second output having a second spectrum, the first spectrum being different than the second spectrum; and
b) independently controlling at least one of the first output and the second output so as to vary a spectral content of the variable color light,wherein the step b) comprises dynamically varying over a period of time at least one of the first output and the second output, whereby the spectral content of the variable color light varies over the period of time in response to at least one action of a person in a vicinity of the at least one article.

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.

8. A method of providing illumination in a marketplace, comprising:
-
a) illuminating at least one article in the marketplace with variable color light from a plurality of LEDs, the marketplace comprising a consumer environment configured for the sale or purchase of goods or services, the plurality of LEDs comprising a first LED providing a first output having a first spectrum and a second LED providing a second output having a second spectrum, the first spectrum being different than the second spectrum; and b) independently controlling at least one of the first output and the second output so as to vary a spectral content of the variable color light, wherein the step b) comprises a step of independently controlling at least one of the first output and the second output (i) in response to at least one sensed condition, (ii) based on a time of day, or (iii) based on ambient light in a vicinity of the at least one article. - View Dependent Claims (9, 10, 11)

12. A method of providing illumination in a marketplace, comprising:
-
a) illuminating at least one article in the marketplace with variable color light from a plurality of LEDs, the marketplace comprising a consumer environment configured for the sale or purchase of goods or services, the plurality of LEDs comprising a first LED providing a first output having a first spectrum and a second LED providing a second output having a second spectrum, the first spectrum being different than the second spectrum; and b) independently controlling at least one of the first output and the second output so as to vary a spectral content of the variable color light, wherein the step b) comprises a step of independently controlling at least one of the first output and the second output in response to at least one action of a customer viewing the at least one article. - View Dependent Claims (13, 14)
