KNX (linear) curve
Selecting the KNX (linear) curve in the gateway maps the brightness value received by the KNX directly
to the lamp power (Y value). There is no linear transformation.
The KNX brightness value received by the gateway is mapped directly to the lamp power. The logarithmic
dimming curve calculates the DALI value, so that for the KNX there is linear mapping between the KNX
value and the lamp power.
KNX value (A) = Luminous flux (B)
– log. Calculation ->
