Lumileds partners with Legrand to accelerate adoption of tunable white LED lighting

Oct. 20, 2018
Lumileds' Luxeon white LEDs will be integrated into Legrand's blanco LED light engines for color-temperature adjustability.
Luxeon LEDs (Image: Lumileds)Lumileds (San Jose, CA) and Legrand, North & Central America (US headquarters, West Hartford, CT) have entered into a partnership aiming to bring to market tunable white lighting that is easy to integrate and install. Under the agreement, Lumileds will provide intelligent light sources (Luxeon-based) through its Matrix platform that are programmed to work with Legrand’s Wattstopper blanco tunable-white logic modules. Lumileds joins existing Legrand partnerships in tunable-white light engines as the exclusive LED array provider. "The lighting industry is beginning the transition from providing only static white light to enabling dynamic end user-selectable color temperature solutions as a subset of what is becoming possible with intelligent and human-centric lighting fixtures and controls," says Steve Barlow, senior vice president and general manager of Lumileds' illumination business. "Our joint commitment is to optimize the customer experience by offering perfect fixture-to-fixture color matching over a wide CCT [correlated color temperature] range through simple, seamless integration of light sources into fixtures that interface with Wattstopper tunable white modules and their lighting controls." The partnership, which combines expertise in LED light sources, drivers, and controls with the blanco intellectual property from Lumenetix, is aimed at providing tunable white-light systems for applications across commercial, healthcare, hospitality, and education market segments. Legrand’s Wattstopper blanco 2 is a two-channel LED light engine providing high-quality light with a tunable range of 3000 K to 5000 K. With a tunable range of 2700 K to 6500 K, blanco 3 is a three-channel LED light engine that adjusts correlated color temperatures precisely along the blackbody locus to replicate natural daylight. blanco logic modules connect to dedicated LED arrays developed by Lumileds high performance Luxeon LED-based matrix platform. Both blanco light engines provide white light with a color rendering index (CRI) and TM-30 fidelity index of at least 90. Both modules also provide flicker-free dimming from 100% to 0.1%. Source:
