Why Choose KNX Smart Lighting?

The KNX smart lighting goes well beyond simple on/off. It creates personalised lighting ambiences that adapt to your activities, the time of day and natural light. The result? Optimal visual comfort and significant energy savings.

LED Dimming

0-100% progressive and silent

Scenarios

Pre-programmed ambiences

Automation

Presence, schedule, brightness

KNX Lighting Features

Dimmable LED Control

The intensity dimming is at the heart of smart lighting. KNX enables LED dimming from 0 to 100% progressively and without flicker thanks to dedicated dimmer actuators.

0-100% Dimming

Progressive and smooth

Level Memory

Recall of last used level

LED Compatible

All types of dimmable LEDs

DALI Interface

For professional lighting

RGB and Tunable White

Colour and temperature variation

Soft Start/Stop

Progressive on/off

Lighting Scenarios

The lighting scenarios enable the creation of predefined ambiences activatable in one click:

"Dinner" Scenario

  • • Table pendant: 60% (2700K)
  • • Kitchen spots: 30%
  • • LED strip: 20% ambience
  • • Indirect lighting: active

"Reading" Scenario

  • • Reading lamp: 100% (4000K)
  • • Ceiling light: 40%
  • • Other sources: off
  • • Focus on reading zone

Presence Detection

The KNX presence detectors automate lighting according to actual room occupancy. This is the most important source of savings:

  • Hallways: automatic lighting on passage
  • WC/Bathroom: switch off after time delay
  • Office: maintained if presence detected
  • Staircase: zone-guided lighting

Circadian Lighting (Human Centric Lighting)

What is Circadian Lighting?

Circadian lighting automatically adapts the colour temperature according to the time to respect your biological rhythm:

  • Morning: Cool light (5000-6500K) for waking
  • Day: Neutral light (4000K) for concentration
  • Evening: Warm light (2700-3000K) for relaxation
  • Night: Very warm light (2200K) without sleep disturbance

KNX-DALI Integration

For demanding projects, the KNX-DALI association offers the best of both worlds:

  • DALI: Specialised lighting protocol (fine dimming, individual addressing)
  • KNX: Global orchestration (scenarios, multifunction integration)
  • KNX-DALI gateway: Interface between the two protocols

Smart Lighting Budget

Estimate for 150m² House

  • Dimmer actuators (8 circuits): €800 - €1,200
  • Presence detectors (6 rooms): €600 - €900
  • Scenario switches: €400 - €800
  • Brightness sensor: €100 - €200
  • ETS programming: €500 - €1,000
  • Total: €2,400 - €4,100

Typical ROI: 4-6 years thanks to energy savings (40-60%)

Frequently Asked Questions (FAQ)

What savings can be achieved with KNX smart lighting?

KNX smart lighting enables savings of 40 to 60% thanks to presence detection, dimming according to natural light and automatic switch-off of unoccupied rooms.

What is KNX circadian lighting?

Circadian lighting automatically adapts the colour temperature (from 2700K warm to 6500K cool) according to the time to respect your biological rhythm and improve sleep.

Is KNX compatible with DALI LEDs?

Yes, KNX interfaces perfectly with the DALI protocol via dedicated gateways. DALI manages fine LED dimming while KNX orchestrates global scenarios.

How do you create lighting scenarios with KNX?

Scenarios are programmed via the ETS software. A simple button can activate a complete ambience: intensity, colour and distribution of lighting in several rooms simultaneously.

Conclusion

The KNX smart lighting transforms the way you experience light. From personalised scenarios to substantial savings, including circadian lighting for your wellbeing, the possibilities are endless to create the perfect ambience in every room.
