DALI device type 8 (Color control) as stipulated in IEC62386-209:2011 works well with the
tunable white application. The light intensities
and color temperatures of the tunable white LED modules can be programmed easily by an application in
DaliSuites.
Two types of tunable white LED modules are offered, namely
TWstrip linear module, and
TWpuck round module. Each module is soldered with two separate LED strings. One string is
of warm white color LED lamps, which is of 2700K CCT. The other string is of cool white color LED lamps,
which is of 6500K CCT. By adjusting individually the light intensities of those
two LED strings, desired color temperature can then be achieved.
