Is there a way to reduce the number of addresses required for managing an RGB or RGBW LED module?

Technical Application Knowledge: From practice, for practice

A DALI controller can manage up to 128 DALI addresses. With this in mind, it was even more regrettable that four DALI addresses were required to manage a single RGBW LED module.
For this reason, the DALI Alliance has now released a new operating mode that minimizes the number of DALI addresses necessary to manage the multi-channel LED load – and INVENTRONICS has already implemented this new feature called DT8-RGBW in its new OTi DALI 50/220-240/ 24 4CH DT6/8 G3, OTi DALI 80/220-240/ 24 4CH DT6/8 G3 and OTi DALI 210/220-240/24 4 CH DT6/8 P drivers!

With this DT8 RGBW operating mode, one single  DALI address is sufficient to control 3 channels (as with RGB product) or 4 channels (as with RGBW). Thus, the installer can save up to 75% of the addresses and later use them for other parts of the lighting installation.

Furthermore, the DT8 RGBW profile allows the user to independently manage each  output channel; each of these channels can be controlled in the 0.1% to 100% range.

Thus, all the light scenarios that a customer wants to create can be defined with the least possible complexity.

DT8 RGBW can be activated as follows:

  • via Tuner4Tronic (T4T), the free programming tool used to fix all the parameters in our DALI drivers;
  • via DALI MAGIC, the controller for uploading the configuration previously prepared in the T4T environment into the driver.

The same operating mode will soon also be available for the new OTi DALI 100/220-240/24 4 CH DT6/8 P.

Thus, outdoor applications (facade lighting,..) can also benefit from this new operating mode and the number of controllers usually required in a DALI network can be significantly reduced.
