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.
The invention claimed is: 1. 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 fixture including: at least one first white LED characterized by a first spectrum
The invention claimed is: 1. 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 fixture including: at least one first white LED characterized by a first spectrum having a first color temperature, the at least one first white LED including a first phosphor, the at least one first white LED generating at least one first wavelength that is converted by the first phosphor to provide the first spectrum; and at least one second white LED characterized by a second spectrum having a second color temperature different than the first color temperature, the at least one second white LED including a second phosphor, the at least one second white LED generating at least one second wavelength that is converted by the second phosphor to provide the second spectrum, wherein the at least one LED-based light fixture is configured such that radiation comprising essentially white light based at least on the first spectrum and/or the second spectrum, when generated by the at least one LED-based light fixture, 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 first white LED and the at least one second white LED and configured to control the at least one first white LED and the at least one second white LED so as to dynamically vary over time a third color temperature of the essentially white light. 2. The system of claim 1, wherein the marketplace comprises an environment configured for the provision of personal grooming or beauty-related goods or services. 3. The system of claim 1, wherein the at least one controller is configured to dynamically vary the third color temperature of the essentially white light so as to simulate at least one indoor lighting condition. 4. The system of claim 1, wherein the at least one controller is configured to dynamically vary the third color temperature of the essentially white light so as to simulate at least one outdoor lighting condition. 5. The system of claim 1, wherein the at least one article comprises a food item. 6. The system of claim 1, wherein the at least one article comprises an article of jewelry. 7. The system of claim 1, wherein the at least one article comprises an article of clothing. 8. The system of claim 1, wherein the at least one article comprises an article of furniture. 9. The system of claim 1, wherein the at least one article comprises an automobile. 10. The system of claim 1, wherein the at least one article comprises an item of home décor. 11. The system of claim 1, wherein the at least one article comprises a cosmetic item. 12. The system of claim 1, wherein the at least one article comprises a still graphic image. 13. The system of claim 12, wherein the at least one article comprises one of a photograph, a slide, and a painting. 14. The system of claim 1, wherein the marketplace comprises a dressing room and wherein the article is disposed in the dressing room. 15. The system of claim 1, wherein the marketplace comprises a display case and wherein the article is disposed in the display case. 16. The system of claim 1, wherein the at least one controller is configured to dynamically vary the third color temperature of the essentially white light in response to at least one sensed condition. 17. The system of claim 16, further comprising at least one sensor coupled to the at least one controller to detect the at least one sensed condition. 18. The system of claim 1, wherein the at least one controller is configured to dynamically vary the third color temperature of the essentially white light in response to at least one action of a person in the vicinity of the at least one article. 19. The system of claim 18, further comprising at least one user interface coupled to the at least one controller and configured to allow the person in the vicinity of the at least one article to dynamically vary the third color temperature of the essentially white light. 20. The system of claim 1, wherein the at least one LED-based light fixture comprises a first LED-based light fixture and a second LED-based light fixture, the first LED-based light fixture and the second LED-based light fixture constituting a networked lighting system and each being configured to be controlled by at least one network control signal. 21. The system of claim 1, wherein the at least one article comprises a first article and a second article, wherein the at least one LED-based light fixture comprises a first LED-based light fixture and a second LED-based light fixture, and wherein the first LED-based light fixture is arranged to illuminate the first article and the second LED-based light fixture is arranged to illuminate the second article. 22. The system of claim 1, wherein the at least one controller is configured to control at least one of a UV component and an JR component of the essentially white light. 23. The system of claim 1, wherein the at least one controller comprises at least one addressable controller configured to receive and process lighting instructions that are formatted as at least one network control signal, the at least one addressable controller configured to dynamically vary the third color temperature of the essentially white light in response to the at least one network control signal. 24. 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 on LED-based light fixture including: at least one first white LED characterized by a first spectrum having a first color temperature; and at least one second white LED characterized by a second spectrum having a second color temperature different than the first color temperature, wherein the at least one LED-based light fixture is configured such that radiation comprising essentially white light based at least on the first spectrum and/or the second spectrum, when generated by the at least one LED-based light fixture, 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 first white LED and the at least one second white LED and configured to control the at least one first white LED and the at least one second white LED so as to dynamically vary over time a third color temperature of the essentially white light in response to at least one sensed condition. 25. The system of claim 24, wherein the at least one controller is at least partially included in the at least one LED-based light fixture. 26.
