Bridgelux Launches New “Human Centric” Chip-on-Board LED Arrays by using Gamut Area Index (GAI)

Bridgelux, a leading developer and manufacturer of LED lighting technologies, will debut its new Vero® Décor Series™ Class A Chip-on-Board (CoB) LED array products at the Hong Kong International Lighting Fair 2014. The launch of the Décor Series Class A arrays marks Bridgelux’s new “human-centric” approach to product development and color targeting by using Gamut Area Index (GAI) to measure how light and color appeals to and is perceived by the human brain.

Available through global channels in mid-November, the new Décor Series Class A arrays are the first products to use the full Class A Color specification from the Lighting Research Center (LRC) at Rensselaer Polytechnic Institute and the Alliance for Solid-State Illumination Systems and Technologies (ASSIST).

In research and development since 2002, Class A Color was created at the LRC with funding by ASSIST.  Class A Color redefines high color quality of light. The long-term study examined how people perceive white light sources and what they prefer in terms of color rendering and the white hue or tint of a light source. Bridgelux specifiers and engineers developed prototype lamps based on the Class A Color spectral requirements for the LRC to use in field evaluations.

“Class A Color has been broadly tested and ‘tuned’ to ensure the most pleasing blend of naturalness and vividness based on subjective human perceptions,” said Jean Paul Freyssinier, senior research scientist at the Lighting Research Center. “A majority (75 percent) of those tested from around the world agree that Class A Color light sources provide the best color rendering and optimum saturation levels. It’s consistent lighting that won’t disappoint.”

Distinguished by its human appeal, brightness and natural rendering, Class A colors are inherently more vivid and whites are their whitest due to a broader spectrum of colors and saturation. By achieving a balance of color properties that match how people perceive color, the Bridgelux Décor Series Class A LED arrays not only deliver superior color quality, but provide a better return on investment when compared to traditional halogen and ceramic metal halide bulbs.

Décor Series Class A LEDs consume 30 percent less energy, generate 70 percent less heat, and last 20 times longer than halogen or metal halide light sources.

Lighting has become a critical design feature for high-end retail and commercial spaces, with solid-state LED technologies playing a vital role in helping businesses differentiate and stand out to their customers.  Whether creating ambience in a luxury hotel lobby, showcasing merchandise in a retail store or illuminating museum works of art, Décor Series Class A LED arrays deliver a stunning visual experience by appealing to people’s natural perception of light, helping to drive improved aesthetics, increased visits, customer purchases and revenue per square foot.

“The launch of our Décor Series Class A LED arrays is a game changer for Bridgelux, our customers and the industry,” said Brad Bullington, CEO of Bridgelux. “Light has the power to influence how people behave, what they purchase, their productivity and their mood. Our new human-centric approach harnesses that potential to help our customers create custom light experiences that deliver great aesthetics and a tangible financial impact.”

Traditionally, the lighting industry uses Color Rendering Index (CRI) as a primary measure of light quality; however, CRI only measures color distortion. Gamut Area Index (GAI) measures color saturation and strength to more accurately reflect the holistic effect of light and how a person will perceive color.  Bridgelux Décor Series Class A is engineered at the optimal GAI and CRI combination based on human perception of light.

Bridgelux Vero Décor Series Class A arrays will be available in 4000 K and 3000 K CCT. They’re designed for applications including high-end retail, hospitality, museums and commercial spaces.
