Color temperature of cold white LED
Color temperature of warm white LED
The specified color temperature of the respective LED must be
entered here.
Color mapping for cold white
Color mapping for warm white
Enables the color matching of the respective LED.
In Tunable White mode, the LEDs for cold and warm
white are coupled, so when using color mapping, make
sure that the maximum output of a channel or the
entire device is not exceeded at any time.
Function of color mapping
Here it can be specified which PWM values are output by the
dimming outputs for cold or warm white, when the dimming
channel has reached a certain color temperature. The following
options are available:
-
Linear
-
Logarithmic
-
User defined
-
Gamma
Gamma correction according to the formula:
Gamma is adjustable via parameter from 1.00 to 5.00
-
DALI
Function based on DALI with the formula:
Output of cold white LED at x%
Output of warm white LED at x%
For the "Linear", "Logarithmic" and "User defined" dimming
curves, these values determine the PWM values of a dimming
output at the specified dimming value. Values between the spec-
ified points are calculated and output linearly. As an example, a
dimming output with dimming curve "Logarithmic" behaves ac-
cording to the following graph:
The output values are fixed for the "Linear" and "Logarithmic"
dimming curves, and can be freely configured for the "User-de-
fined" curves.
If a dimming value of 0% is reached, the channel always
switches off.
Adjustment of cold white LED
Adjustment of warm white LED
The PWM value of the color temperature calculated by the dim-
ming curve is additionally scaled with this value.
State object color temperature of cold white LED
State object color temperature of warm white LED
When activated, the following objects become visible:

These objects transmit the parameterized color temperatures of
the cold and warm white LEDs once when the device is started.
The values are also available for read requests.
