White LED platform eases colour tuning for human centric lighting
Combining the needs of many tuning technologies, including dim to warm and dynamic tuning for human centric lighting, the Luxeon Fusion addresses colour temperatures from 1,800K to 10,000K with high colour-rendering index (CRI) (over the 90 to 95% of range) and high colour fidelity. When lighting hospitals, restaurants, offices or retail venues, designers often wish to adjust colour temperature on-site or program it to adjust light levels throughout the day to complement a changing ambient environment. The Luxeon Fusion is easily integrated with a variety of wired and wireless (e.g. Digital Addressable Lighting Interface (DALI), Digital Multiplex (DMX), Wi-Fi) approaches for on-demand tuning.
The first implementation of Luxeon Fusion involves modules for downlights, spotlights, troffers and linear applications. “We boosted LED utilization by 25 to 100 percent over standard two-LED or three-LED solutions, and achieve consistent light output over the tuning range – something customers value and other color tuning systems struggled to deliver,” commented Greg Tashjian, Senior Director of R&D at Lumileds.
A fixture offered with CCTs (correlated color temperature) of 2700K, 3500K and 5000K colour temperatures, each with specific light engines and SKUs can now utilize one engine for all the fixtures and CCT can be set later, even after fixture installation. Another use involves high-impact retail environments, where companies select a signature CCT and brand all stores worldwide with one color tone.
