Light a natural factor, enables us to see our world in vibrant color and striking details. It also acts as an indication of when our body must wake up and sleep. If you acutely discern from sunrise to sunset, the color and intensity of the light fluctuates from warm amber to bright light during the day, and back to warm light at sunset, followed by darkness in the night. The nature set-cycle of light brightness and intensity has an intense influence upon health of living beings as it affects the body’s circadian system. The human body has a 24 hour rhythm that has established sleep/wake patterns, and control of physiological functions such as hunger, temperature and blood pressure. When our body is in sync with the rhythm, we feel energized and stabilized, if not we feel drained and lethargic. The minute we wake up, our body gets introduced to lights and the time we snooze, we switch off all our light resources for getting proper uninterrupted sleep.

A new light ceiling spans the counter hall at Valiant bank at Bahnhofplatz in Bern. But instead of daylight, the large-format ceiling panels are backlit by LED technology from Tridonic. With its Tunable White function, the solution picks up on the dynamic properties of natural light and enables variable light colours to be generated, ranging from warm and neutral white to cold white.

Combining a compact form factor with the latest platform features, the LuxiTune 2.3 tunable white light engine announced by LED Engin, Inc., a leader in high flux density LED products, targets the same track-lighting and small down-lighting applications as its Gen 2.0 products, while delivering the added performance and controllability benefits that were introduced with Gen 3.0. These advances, which include smooth deep dimming to 0.5%, no e-flicker and no visible flicker, also extend to additional control interfaces for DALI, DMX-RDM and Bluetooth Low-Energy (BLE) through daughter cards, that customers can chose to wire into their fixtures.
