New generation of Tunable White system (SELV) with high colour consistency

Second generation Tunable White systems consist of two to six linear or area LED modules and corresponding DALI DT8 LED drivers. They cover the entire colour temperature spectrum from 2,700 to 6,500 K, have an extended dimming range and together with appropriate control components, provide the hardware basis for human centric lighting.

The new system generation with Tunable White (TW) offers even better light quality (CRI>90 and MacAdam 3) with high visual comfort and are also SELV customized. With calibrated kits from Tridonic a the light will have a homogenous apparence over the entire lifetime without any shifts in the consistency of luminous flux or coulour temperature. The system can be dimmed from 100 to 3 percent, exclusively via amplitude modulation. There is therefore no dimming flicker. The integrated DALI interface DT8 enables the kit to be easily connected to central light management systems.

The colour temperature can be infinitely adjusted between 2,700 and 6,500 K via a sophisticated calibration algorithm in all the possible combinations. This means that the natural changes in daylight can be simulated and matched precisely to the lighting task. The driver is equipped with colourSWITCH and switchDIM so the colour temperature and dimming level can be easily changed using two buttons. This is also possible from a momentary-action switch or smartphone via basicDIM Wireless.
This combination is of great benefit for offices, shops, educational establishments and medical facilities because the right light can be produced for any particular lighting application and enhance the well-being of users.
