METHODS AND APPARATUS FOR GENERATING AND MODULATING WHITE LIGHT ILLUMINATION CONDITIONS
First Claim
1. A method of providing illumination in a marketplace, comprising:
- a) generating radiation using a plurality of LEDs including at least one white LED, the radiation comprising essentially white light and having an adjustable spectral content;
b) illuminating at least one article in the marketplace with the generated radiation, the marketplace comprising a consumer environment configured for the sale or purchase of goods or services; and
c) controlling the spectral content of the generated radiation.

Abstract
Methods and apparatus for generating and modulating white light illumination conditions. Examples of applications in which such methods and apparatus may be implemented include retail environments (e.g., food, clothing, jewelry, paint, furniture, fabrics, etc.) or service environments (e.g., cosmetics, hair and beauty salons and spas, photography, etc.) where visible aspects of the products/services being offered are significant in attracting sales of the products/services. Other applications include theatre and cinema, medical and dental implementations, as well as vehicle-based (automotive) implementations. In another example, a personal grooming apparatus includes one or more light sources disposed in proximity to a mirror and configured to generate variable color light, including essentially white light, whose color temperature may be controlled by a user.

12. An illumination system for a marketplace that comprises a consumer environment configured for the sale or purchase of goods or services, the system comprising:
-
at least one LED-based light source including at least one white LED and configured such that radiation comprising essentially white light, when generated by the source, impinges on at least one article disposed within the consumer environment for sale to a purchaser; and
at least one controller coupled to the at least one LED-based light source and configured to control a spectral content of the radiation. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36)
