KNX lighting control covers switch actuators for on/off loads, universal dimmers for LED and other dimmable loads, and KNX-DALI gateways that bring DALI drivers and luminaires onto the KNX bus. Push buttons, presence detectors and timers send the commands; the actuators in the distribution board do the switching.
Compare channel count, rated current, load type and mounting (DIN rail or flush), then add the devices to the project planner.
Frequently asked questions
When should I use a DALI gateway instead of KNX dimmers?
For many luminaires, as in offices and hotels, a KNX-DALI gateway controls dozens of DALI drivers over one two-wire DALI line, which is usually simpler than one dimmer channel per circuit. KNX dimmers suit a smaller number of circuits with dimmable loads.
How do I size a switch actuator?
Check the rated current per channel and the load type. LED drivers have high inrush currents, so use actuators rated for capacitive (C) loads and stay within the manufacturer's limits per channel.
Can KNX lighting work with presence detectors?
Yes. KNX presence and motion detectors switch or dim lighting directly, and many also measure daylight for constant light control.
