Osram Launches Digital Tunable White System

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.
