Abstract
Lighting methods and systems to enhance the browsing behaviors of shoppers in a manner intended to be primarily subconscious include illumination of a targeted area, such as a typical retail display, with a tunable spectrum lamp that slowly cycles through different illumination spectra such that color rendering of illuminated target is deliberately varied for subtle arousal of the visual senses. The illumination spectra, and the rates at which spectral conditions are changed, are both chosen as such that multi-colored objects in the targeted area change in appearance in a barely noticeable way, such that shoppers may find their visual attention redirected, seemingly at random, to a wider variety of products on display. Color spectrum changes also may be controlled in coordination with predefined packaging colors to create quasi-animation effects.
