How LEDs Are Changing the Retail World (IEEE – The Institute)


The technology is influencing purchasing decisions

Let’s begin at the store’s windows and entrance, where the decision to stop in or move on is often made. The ability to adjust from warmer to cooler shades of white, referred to as color tuning—along with precise light distribution—allows the retailer to create an inviting space that appeals to the shopper’s sense of comfort, safety, and familiarity. Once inside, LEDs’ plethora of physical configurations, including recessed lighting, track lighting, and wall lighting, allow the presentation of a variety of inviting environments in different parts of the store. By illuminating the merchandise, accent lighting—combined with lower levels of surrounding light—can encourage shoppers to linger at certain shelves and racks. The positioning of lights above the aisle ends helps drive customers through the store and discourages bottlenecks.

Whether it’s a red tomato, a bright blue sweater, or a sparkling piece of jewelry, LEDs’ color-tuning capability provides retailers with flexibility in optimizing the appearance of their offerings. A cooler white light approximating daylight could enhance the sparkle factor of cut gemstones, for example, while a warmer white light could make the reds, oranges, and yellows of a floral display really pop. For food in particular, LEDs can help increase shelf life and enhance appearance. Exposure to ultraviolet and infrared radiation can result in degradation of food’s appearance and nutritional value; LEDs used for general illumination contain no ultraviolet or infrared in their output.
