Tunable White light gives you the option of setting the colour temperature of white light to any value.
With the right colour temperature and illumination it is possible to feel comfortable despite artificial lighting whether you are working in an office, studying at university or recovering in hospital. The “Tunable White” solution simulates natural daylight and can adapt to personal requirements. For example, the well-being of patients in healthcare facilities is improved and the healing process is accelerated. Students and office workers also benefit from this lighting system as they are able to concentrate for longer and are more productive.
Tunable white provides a great way to optimise the colour temperature of LED lighting. It operates via a KNX/ DALI gateway and compatible DALI drivers, but they must meet the DALI DT 8 driver specification.
Tunable white enables the lamp’s colour to be set and/or changed to suit the mood. This has been shown to affect the body’s circadian rhythms – the body’s natural time clock that tells you when to sleep, wake and relax.
DALI Gateway introduces control of DALI ballasts and fittings that are Device Type 8. This allows control of the colour temperature making it possible to create human centric lighting based on the time of the day and room requirements. Colour temperature has a direct impact on our bio-rhythms so by controlling it as part of an intelligent lighting systems it is possible to influence the mood and behaviour of those in the room.
Via KNX the Gateway can change the colour temperature of DALI groups or individual addresses, or the integrated timer can be used to fully automate the system.
It is also possible to link the colour temperature with the brightness value making it possible to mimic the dimming characteristic of more traditional light sources such as incandescent. Colour temperature can also be linked to scenes or sequences taking the creation of lighting effects to another level.
Using KNX/Dali gateways to support a full DALI installation of 64 devices and the possibility to mix individual and grouped DALI commands, the gateway is very flexible and suited to both residential and commercial projects.
