OSRAM LAUNCHES DIGITAL TUNABLE WHITE SYSTEM
20.Feb
2019

Wilmington, Mass. – Osram, a leading global lighting and technology company, today announced the launch of a digital tunable white (TW) system based on DALI-2 designed for human centric lighting (HCL) applications in educational, commercial office and healthcare settings. The system consists of an OPTOTRONIC® Tunable White two-channel Programmable LED Driver, OSRAM Tunable White Wallstation, PrevaLED® Tunable White Light Engine, and optional OSRAM Control Power Pack. The TW Wallstation sends preset scene commands to the OPTOTRONIC TW LED Driver, which is preprogrammed to specific Correlated Color Temperatures (CCT) between 2700K-6500K and light intensities between 1-100 percent. Wallstation lighting scenes can be reprogrammed by the end user, offering the flexibility that some customers require. The PrevaLED TW Light Engine is recommended as part of this solution for optimal performance, however, the OPTOTRONIC TW LED Driver also can be paired with third-party tunable white light engines. The TW System can be used as a standalone system or as part of a connected solution.

 


HCL brings daylight indoors by reproducing the natural hues and brightness of nature. This dynamic natural light positively impacts human wellbeing by helping to regulate our circadian rhythm, which is our 24 hour sleep-wake cycle. Every day, the human body’s circadian rhythm is reset by exposure to light. However, irregular exposure to daylight can lead to adverse health effects including depression, sleep disorders, obesity, fatigue, and other issues. HCL technology such as Osram’s TW system mimics the natural daylight cycle, making it ideally suited for classrooms where student focus is important, offices where concentration is important, and skilled nursing or hospital patient rooms where occupants may experience sleep cycle issues and other health-related problems.

“Human centric lighting can benefit human health and wellbeing but often tunable white solutions compromise on light quality and can be difficult to install, commission and use,” said Naveen Tumula, product group marketing manager, Osram Digital Systems, Americas region. “For those environments that need a centrally managed, connected solution, this tunable white system is compatible with light management systems capable of communicating via DALI-2 for type 8 devices. It is also easy to implement as a standalone solution.”

Digital-based systems ensure consistent light quality regardless of the size of the space. Analog-based systems can have a variation in lighting quality from fixture to fixture due to signal inconsistency, whereas digital control ensures high quality, consistent light levels across luminaires. The Osram digital TW System leverages DALI-2 standardized commands for color tuning.
